Java Applications and GPS Enabled
Some Java applications can make use of your phones GPS feature to determine the approximate geographical location of your phone. (See GPS (Global Positioning System) Enabled on page 108 for more information on the GPS feature.) However, for privacy reasons, you may not always want Java applications to access the location of your phone. Your phone protects your privacy by giving you the option to block all or some Java applications from accessing the location of your phone.

Enhancing GPS Performance
Sometimes the GPS feature of your phone may be unable to complete a location calculation successfully. If this happens when you are making an emergency call, the location of the nearest cell tower in contact with your phone is made available to the appropriate emergency response center if the center has the capability to receive such information. If this happens when you are trying to view your location on the phones display, you will see a message indicating that your phone cannot access satellites.
GPS (Global Positioning System) Enabled To improve accuracy and increase your chances of a successful calculation, do the following while your phone is determining your approximate location: Stay in the open. The GPS feature works best where there is nothing between your phone and a large amount of open sky. If possible, go outside, away from tall buildings and foliage. While performance in a building is improved by moving closer to windows, glass with certain sun shielding films may block satellite signals. Extend your phone antenna. Hold your phone to enhance reception. Signals from GPS satellites are transmitted to your GPS antenna, which is in your phone antenna. Hold your phone away from your body, giving the antenna clear access to satellite signals. Do not cover the antenna area with your fingers or anything else.

GPS antenna

Updating Satellite Almanac Data Stand still. If possible, stand still until your phone is finished determining your location. Moving your phone at a walking pace while your phone is calculating your approximate location may substantially decrease GPS performance. In a car. When using the GPS Enabled feature in a car, position your phone so that the GPS antenna has good access to GPS signals through the cars windows. Typically, the GPS antenna has best access to GPS signals in a car when placed near a window. Note: Although moving your phone at a walking pace decreases GPS performance, moving it at the speed of a moving car does not. Stay in network coverage. Depending on who your service provider is, the network will provide your phone with information that helps determine your location more quickly and accurately. The United States government maintains an almanac of data about where GPS satellites are as they orbit the Earth. This information is available to your phone. Keeping your satellite almanac up to date helps your phone determine your location more quickly. The almanac contains information about the location of satellites, their operational status, and other satellite information. Keeping this information updated enhances the performance of your GPS feature. In most cases, your phone will be able to get a fix in strong satellite signal conditions with outdated almanac data, but it may take longer. Note: When you make an emergency call, your phone does not rely upon the almanac to determine your location. If your satellite almanac data is out of date, your phone may prompt you to update it. Follow the instructions that appear on the phones display. You may be asked to go to a web site or call a customer care number.

Two-way radio operation

Your radio product has been designed and tested to comply with national and international standards and guidelines regarding human exposure to RF electromagnetic energy, when operated in the two-way mode (at the face, or at the abdomen when using an audio accessory) at usage factors of up to 50% talk/50% listen. Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time or less, is important because this radio generates measurable RF energy only when transmitting (in terms of measuring for standards compliance).
ALL MODELS WITH FCC ID AZ489FT5844 MEET THE GOVERNMENTS REQUIREMENTS FOR EXPOSURE TO RADIO WAVES. Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.1 Tests for SAR are conducted using standard operating positions reviewed by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a phone model is available for sale to the public, it must be tested and certified to the FCC that is does not exceed the limit established by the government-adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. The highest SAR value for this model phone when tested for use at the ear is 1.05 W/kg and when tested on the body, as described in this user guide, is 1.15 W/kg during packet data transmission. (Body-worn measurements differ among phone models, depending upon available accessories and FCC requirements.)2 While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement for safe exposure. The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model phone is on file with the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid after searching on FCC ID AZ489FT5844.

Organization

Reasons for Considering iDEN
Traditional PTT radio communications in corporate and municipal environments was limited by the number of radios and Federal Communication Commission (FCC) licensing. These restrictions limited the coverage area, contact outside the assigned, licensed mobile units, and provided little privacy. The iDEN system: Removes end-user FCC licensing requirements Opens communication to other subscriber corporations and all telephones1 Increases the coverage area Allows private and group calling Optimizes RF resources Improves quality with higher frequencies and digital technology Because of the finite availability of the Radio Frequency (RF) spectrum and a need to optimize this resource, iDEN technology increases the efficiency of a single 25 KHz RF carrier by applying up to six times the traffic of an AMPS Cellular carrier. In addition to the increased channel efficiency, an iDEN system may be deployed to support communications outside the providers network (roaming). The telephonestyle interconnect capability allows users to roam seamlessly throughout linked service areas. A user may place and receive calls as if the Mobile Station (MS) is on its home system. This also allows the service provider to offer an integrated service that includes: Messaging (Short Message Service) Private, Two-way & Group Call Cellular Telephony Service Voice Mail Data Networking (Intranet, Virtual Private Network (VPN), Internet). Since the iDEN system uses digital technology, it provides clear voice quality, interference is reduced and voice quality is enhanced. As the wireless industry grows, subscribers are seeking more services and increased functionality from a single service provider. With iDEN systems, these services and system outgrowth can easily and quickly be provisioned and made available to the end user because the radio link reduces installation time and cost when compared to land-based approaches.
To support the growing need for emerging telecommunications services, iDEN systems are organized into different levels or areas. These areas are based on geographical areas of decreasing size. The areas are: Global Region Domain Service Area Location Area Cell

Introduction 1-4 68P81095E55-E August 08, 2000
A Fleet is a logical organization of people and/or systems (users) that require mobility. In the broadest terms, a fleet is a subscriber. A subscriber can be: An individual A business An agency A government or municipal department An extended family Any functional organization with members that communicate with each other. The iDEN system provides fleet-based communications with Dispatch call processing (half-duplex mode). Half-duplex mode is also called Push-to-Talk (PTT) because a button is pushed when transmitting (talking) and the same button is released when receiving (listening).

TalkGroup

Each fleet may contain subsets of localized communication. Like lines a multiline telephone each MS may be linked to a talkgroup that includes other fleet members. Individuals or groups may be selected to share in resources to engage in conversation. Large groups can be defined and users may subscribe to memberships in the group. The number of groups and members is flexible. Groups are tailored to fleets and marketing plans. How fleets and talkgroups in the fleets are organized in provisioned in the Dispatch call processing databases.
Users are individuals with network devices (radios, phones and similar devices). Users must be provisioned before they may use the system.

Advantages

The iDEN network products provide several important advantages in wireless communication. Broad capabilities and adaptive design provides: Flexible, multi-national, network scaling Efficient RF Channel usage in several spectrum bandwidths Circuit-switched (dial-up) and Packet-data (IP) digital data networking Dispatch capability for Private, Local and Wide Area Group calling Clear GSM cellular subscriber services Alphanumeric Messaging (Short Messaging Service) Reliable digital communication technology Fully Featured, compact portable devices (Mobile Stations)

Network Scalability

By combining industry standards with modular design elements, iDEN technology provides progressive, manageable, implementation, migration and outgrowth. With consistent design standards and software upgrades, new technologies and enhancements can be implemented on the network that minimize the need for new hardware. The segmentation of tasks and functions to common hardware standards and remotely upgradable software modules allows the implementation of new technologies within the existing infrastructure. By reducing the amount of major changes, the network can be expanded and adapted as demand dictates. As the demands of the market increase, iDEN technology is continuing to provide expandable hardware enhancements and inventive software upgrades that improve reliability and service quality. The development of new technologies is being based on the same principles and standards so migration is structured and more easily managed. This philosophy allows forecasting and capacity planning to adapt to the latest improvements while utilizing existing technology.

Time-Of-Day Processing

Introduction August 08, 2000 68P81095E55-E 1-9
Data Communication Improvements
Data communications handling changes simplify MS configuration, increase capacity, reduce data stream volume and improve routing failure recovery. The improvement to data comminations include: Packet data bootstrap download to simplify re-configuration of MS without a PC or direct cable connection An increase in Mobile Data Gateway (MDG) to increase MDG capacity from 5,000 users to 15,000 users with a software change Packet Data Header Compression to reduce the amount of data transmitted on-air with IP header compression. (This requires IP header compression be enabled on mobile during dial-up data networking) Mobile Internet Protocol (IP) Home Agent Redundancy to help maintain a data link if the master home agent fails by copying binding and routing information to an assigned standby router.

Dispatch Communications

Significant changes in Dispatch Call Processing have been introduced to improve capacity, increase fleet size, allow cross fleet dispatch calls, and to reduce audio degradation (dragging). Cross Fleet Dispatch calling a new identification scheme increases the number of subscribers in a fleet and allow dispatch calls between different fleets. New Dispatch Application Processor (DAP) hardware a new version of the dispatch switch controller and upgrade kits to convert exiting DAPs to the more powerful configuration. Home Location Register Portability SR 8.0 improvements allow the HLR to be on any T-DAP not a dedicated DAP. Private Call Hang Time a new dispatch call parameter to better define call tear down and re-selection when a mobile travels across cell boundaries.
Enhanced Base The Enhanced Base Transceiver System (EBTS) has been expanded and upgraded to Transceiver Station increase frequency range, reduce recovery time and improve alarm and error Improvements reporting Introduction of 821-825 MHz spectrum capabilities Dynamic adjustment of Transmit power on Base Radio Recovery or switchover to redundant control channel Base Radios iDEN Monitor Unit (iMU) Alarm Module Control improvements in monitoring and reporting of EBTS activity. These changes are discussed in greater detail as required throughout this document. Network Management Changes to the hardware and software of the Operations and Maintenance Center (OMC) vastly improve Network Management. These changes are driven by the phasing out of production of the S1000 and OMC 3000 workstations by the supplier. These computers are going out of production so new hardware is being introduced to act as OMC. The changes include: Introduction of the OMC 3500 platform The ability to control multiple frequency bands on one OMC The ability to network OMCs

RF Distribution System

Site Timing Reference
iDEN System 2-4 68P81095E55-E August 08, 2000

LAN Interface

Each EBTS component is monitored and communicates with each other directly or over a LAN. The LAN interface is the path for traffic flow. The LAN also supports the Alarm and Messaging monitoring functions (iMU or BMR/EAS). Operations and Maintenance uses the iMU and the LAN to access the cell site. The LAN is a thinwire, coaxial Ethernet (10base2) that runs Carrier Sense Multiple Access/Collision Detect (CSMA/CD) protocol. This allows the BRs and the iSC to access each other as time and traffic requires with a minimum of control overhead. BR Antennas Antennas will vary with each installation. Each EBTS cell requires has a minimum of one antenna for the radiation and reception of the RF energy that is the Radio Link. There is usually more than one antenna or branched antennas (Diversity Antennas).
Functional Characteristics
The EBTS can be configured to support multiple RF frequencies in a omnidirectional or sectored configuration. Major functions of the EBTS are: Maintenance of the radio link Radio link formatting, coding, timing, error control & framing Timing control supervision to subscriber units (time advance) Radio link quality measurements Signal Quality Estimate (SQE) Recognition and separation of traffic (Interconnect, Dispatch, Circuit Data or Packet Data) Site-to-site frame synchronization Interface conversion - radio link to DS0 Switching functions between base transceivers Operation, maintenance, and administration of Radio Link equipment The EBTS also relieves the network from the lower level site control functions. This helps isolate the central network functions and the RF radio link. Because the EBTS performs most control functions, the number of network messages is minimized. This results in a shorter call setup time and decreased link control overhead. Radio Link Maintenance The basic wireless radio link is a 64 kbs digital baseband signal subdivided into 6 timeslots. Each timeslot at the cell site is a radio link. The MS constantly analyzes the quality of the radio link. When the MS and the FNE determine that a better signal exists and the MSs radio link is processed accordingly.Some of the radio link functions the EBTS is responsible for include: Channel disconnect and failure Trolling contact, position update, and identification of the MS Handover changing to a cell site with a better signal Cell selection choosing a cell to host the MS Disconnect and re-connect

Processing Equipment and Field Replaceable Unit (FRU) level failure reporting Environmental Communication Quality of service data File available Test results available State change events Fault management enables the system operator to detect and respond to network element faults within the system. The OMC provides fault management by using Network Management agents that are resident on the various network elements to pass events to the OMC. The events are reported and identified by priority level. The system operators are able to filter the reporting of events based on priority (severity). For example, if a power amplifier fails on a BR, the BR will send an event message to OMC indicating a failure exists. The system operator can then send a technician. Alarms and Events are stored on the OMC for future reference. If a higher order management Network Maintenance Computer (NMC), is connected to the OMC through a LAN, the event stream can be directed to the NMC for correlation with other events not reported to the OMC. Performance Management The performance management function controls the collection and presentation of metrics to the system operator. These statistics files are stored in a database on the OMC for the creation of reports. There are several generic reports that can be selected for local analysis. The statistics files can be transferred to a higher order manager such as an NMC. Metrics are gathered in four broad categories: Call Processing System Performance Metrics Link Layer Communications Metrics Meta-management Metrics. Call Processing metrics are concerned with the number, duration and quality of calls placed by the end-user for the various types of services available on the network. System Performance metrics relate to service-oriented status and events such as availability and outage impact. The Link Layer Communications metrics provide information on the functional operation of the radio links as discussed in Fault Management of this section. The Meta-management statistics help the system operators control the impact of the management system on the call processing system. Configuration Management Configuration Management is monitoring and control of system and subsystem components for state, software release, and components. The system configuration databases of the DAP, EBTS, BSC, MDG and APDs are downloaded from the OMC. These databases change as the physical configuration of the network expands to accommodate growth. This configuration management relates to:

The authentication key (Ki) is an identification of the algorithm the MS uses to create signature numbers from random numbers. The Random Number is part of the table used to authenticate the MS. This is discussed in greater detail in Authentication previously in this chapter. The Signature Number is part of the table used to authenticate the MS. This is discussed in greater detail in Authentication previously in this chapter. The TMSI is a dynamic interconnect call processing, temporary ID that is used to identify an MS while it is active. This parameter minimizes broadcasting the more critical IMSI over the air. The IMSI is only transmitted when the MS initially roams onto a system and registers. The system assigns a TMSI for the MS immediately that is used to identify the MS until it roams out of the system. A new TMSI is assigned to the MS each time it changes its location area with the VLR.

Random Number

Signature Number
Temporary Mobile Station Identifier
Dispatch Identifiers Several parameters are unique to dispatch call processing. The parameters used to define access and services are: Urban ID Urban ID Fleet ID Group ID Fleet Member ID
The Urban Identifier applies to Software Release 8.0 and above. This ID is used to define the home region (market) of the MS. Motorola assigns Urban ID to markets and regions. Introduction of this ID allows an MS to roam outside the home region and maintain a unique identifier that may be used to control service and permit interregion and cross-fleet dispatch calling (Horizontal Dispatch). A Fleet ID is a number that is assigned by the service provider to distinguish major subscribers (corporate or municipal entities). This defines the largest functional unit of a dispatch call. Individual users are members of fleets. With SR 8.0 the fleet ID may be re-used in different Urban ID areas (regions).
Operating Characteristics

Fleet ID

Talk Group ID
A Talk Group ID (Group ID) is a provider defined number that defines a functional subset of a fleet. The type and number of groups in a fleet will vary with the organization and requirements of each fleet. Each group has a dispatcher (user 0) that is assigned as a logical control point for all dispatch communication. A Fleet Member ID (Member ID) is a number assigned by the provider to uniquely designate an MS. The ID is used to indicate a specific MS during dispatch calls, such as the originator or target MS during a Private Call. It is also used to indicate the specific MS transmitting in the PTT-ID service. Ultimately access and service are designated by Fleet Member ID. Each EBTS on the iDEN system has unique identifiers to coordinate the activity and maintain the integrity of the Radio Link. A list of Site specific parameter values is transmitted on the BCCH by each iDEN cell to MSs on that cell. These values are read and used by each MS as it executes its link control procedures (Chapter D, Handover).

Figure 4-6 Dispatch Call Setup

DGC REQUEST DGC PROCESSING DGC PAGING REQUEST DGC PAGING RESPONSE DGC GRANT INITIATOR DGC GRANT TARGET Three types of Dispatch Group Calls (DGC): Local Area Call - communications between MS in the Home or Local service area. Selected Area Call - communications between a caller and a group in a different service areas. Wide Area Call - communications between a caller and a group anywhere in the network.
If no servers are available at the callers site, the call is queued. If a server is available at the callers site but not at other sites, those sites are included into the call as servers become available. Pages will be sent out only in those Location Areas where active group members are registered (provisioned). Once an MS responds to the page, only those cells with active MSs will have voice channels assigned. After each transmission, the FNE maintains the call for the pre-defined hang time. If the hang time expires, the channels are disconnected and the call is torn down. The types of Dispatch Group Calls that define the extent of the area of the call are: Wide Area, Local Service Area, and Selected Service Area Dispatch Group Calls.
Dispatch Call Processing August 08, 2000 68P81095E55-E 4-9
Local Service Area A Local Area Group call is a voice multicast to members of the fleets group in the Dispatch Group callers service area, the group dispatcher, and members of the group in the Call dispatchers service area (Figure 4-7). Once a group is selected and a Group Call is initiated, all members of the group will be activated on the group call (Table 4-2). Figure 4-7 Local Area Group Calling

Interconnect Call Processing 5-6 68P81095E55-E August 08, 2000

Interconnect Call Types

Mobile Stations on the iDEN system can complete Interconnect Call with other providers networks in three basic ways: Mobile to other network (PSTN) Other Network (PSTN) to Mobile Mobile to Mobile Mobile to Other Network On MS power-up, number entry, and call initiation, the MS sends a service request to the EBTS. The EBTS/BSC/HLR identifies an Interconnect call and routes the request to the MSC through the BSC. When the MSC receives the service request, it queries the HLR and VLR for service access, service availability and MS authentication. When authentication of the MS is complete, the BSC cross connects the RF channel to the land-based circuit as soon as it is assigned by the MSC. The MSC assigns the trunk according to the provisioning of the networks. The MSC then connects the BSC land circuit to the PSTN trunk. When the connect to the PSTN is complete, the remote PSTN will request that the local MSC transmit the dialed digits for the call. The remote PSTN will verify service and the called party and send a cut through supervision (the called party answering or a supervisory tone like a busy signal). The MSC will send a connect message to the MS that allows the MS to receive and transmit voice frames completing the call connection. Other Network To Mobile When an incoming call is received at the MSC in SS7 protocol, a channel to the remote PSTN is allocated and the DTMF digits (dialed number) is received by the MSC. The MSC will query the HLR and VLR databases to verify the dialed number exists and to alias the dialed number to the MS (IMSI or TMSI). The MSC will locate the MS using the Interconnect Location Area (ILA) in the VLR to page the MS. The ILA is used by the BSC to route the call to the most likely set of EBTSs using Radio Link Protocol (RLP). The MSC will wait for the MS to respond to the page. If the MS or resources are unavailable, the MSC will generate the appropriate status return to the remote PSTN (busy or out-of-service). If the MS and resources are available, the MSC will connect the external trunk to the controlling BSC. The BSC will connect the PCM/ SS7 link with the appropriate EBTS span line (T1). The EBTS will establish the radio link, allocate a radio channel and transmit a hail (ring the phone). When the user responds, the BSC/XCDR converts the PCM voice packets to the VSLEP packets used by the radio link. The DAC and BSC completes the cross connect between the radio link and the other provider land-line to complete connection of the call. The MSC may also route the call to the Voice Mail system or to Call Forwarding if the service is provisioned for the MS and the MS is eligible for the re-route.

Inter-System Mobility

For truly mobile computing the iDEN system provides Packet Data remote system usage and roaming. Roaming uses the Home Agent and a Foreign Agent. Each of these is an MDG sub-system that serves an iDEN network. Each agent (MDG) contains a table of the addresses of all the roaming partner/remote MDGs (a virtual network). Each MDG has a Home Agent that lists the packet data services and remote location of the MS. The remote location is the care-of-address that is also the address of the remote MDG. The local MDG (home agent) forwards data to the remote MDG Foreign Agent) while the MS is away from home. This MS mobility binding has contains the IP address, the foreign agents address (care-of-address) and time variable. As long as the mobile does not register in another system, the data will be forwarded to the Foreign Agent (remote MDG). A Foreign Agent is an MDG on the visited network that coordinates the routing of data when an MS roams. The remote system will contact the home system to verify registration, authentication and services. If allowed, the home system will transfer this information to the remote system. The Foreign Agent (MDG) will add the traveling MS to a visitor list and accepts data packets for the local (home) system. Like home system routing, the visited system will locate and route the data packet to the roaming MS. The home MDG will send all data to the visited MDG that in-turn, will route the packet to the remote iDEN system. All roaming system partners are part of a virtual network defined in both systems MDGs.
Packet Data Networking 6-4 68P81095E55-E August 08, 2000

Packet Data Flow

The Packet Data network link is dynamic. The actual data rate and flow will depend on the traffic on the system. As the traffic on the system and the integrity of the radio link changes the radio link can adapt to the optimum date flow rate. To optimize performance and resources the iDEN system uses three principles to control the On-Air interface. Dynamic Channel Allocation Adaptive Rate Modulation Queued Continuous Reservation ALOHA

Specifications

During Circuit Switch (dial-up) data networking, the iDEN system uses: Radio Link Protocol (RLP) Full-Duplex Single rate: 4,800 bits-per-second (4.8 kbs) with 6 users per RF carrier 9900 bits-per-second (9600 baud) with 3 users per RF carrier Flow Control: X-ON / X-OFF or DTS / CTS Error Control: Forward Error Correction Coding (FEC) Selective Retransmission of uncorrectable blocks (selective ARQ)
Circuit Switched Data is a dial-up networking function of the iDEN system. An MS acts as a transport carrier with a compatible modem and a laptop computer or compatible Data Terminal Equipment (DTE). Any mobile connected computing device that is compatible with iDEN equipment may be used to create mobile computing. When a mobile/laptop is engaged in Circuit Switched networking it exists as a dial-up networked device. The mobile computing devices use Transmission Control Protocol/Internet Protocol (TCP/IP), Point-to-Point Protocol (PPP), and Serial Line Interface Protocol (SLIP). The devices on the system must be configured for these parameters. With the introduction of Software Release 8.0, the routing information (IP Header) is compressed to reduce traffic overhead. The computing devices must be configured to de-compress the header for proper processing. An MS may establish a dial-up network connection between itself and fixed end hosts using Interconnect Call Processing procedures.

InterWorking Function

The InterWorking Function (IWF) is a MSC-based optional processor that converts data between PCM standards to the radio link standards used by the iDEN system. The Radio link is converted to PCM and applied to the IWF links (trunks) on outbound links. The IWF also has a modem pool that allows other networks to access the iDEN system for inbound circuit switch data like: Dial-up access to the iDEN system Facsimile (FAX) service (Class 2, Group 3) Teletype (TTY) using Bell 103 compatible modems Non-transparent data services at 9600 bits-per-second (baud). On the inbound link, the IWF translates PCM to the radio link.

The difficulty with isochronous hierarchical timing is that each element in the path introduces a delay. There is also a delay introduced by the propagation time between the elements. With digital switches, this creates a timing problem that requires more hardware and software. The different delay times causes the payload synchronization to be out of step between source and destination elements. The result is that the payload (T1 or E1 frames) become unusable.
Network Planning August 08, 2000 68P81095E55 A-1

Pleisiochronous Timing

To reduce the cost and complexity network timing the iDEN system uses locally recovered timing. Locally recovered timing uses clock signals from the Global Positioning System (GPS). GPS receivers (Stratum 1 clocks) at major network elements receive a highly accurate clock pulse from the GPS system. This single source (plesiochronous) timing is used for bit-rate and frame synchronization throughout the network. The Building Integrated Timing System (BITS) performs the recovery and distribution timing across the network. This provides highly accurate timing to each network element and highly accurate synchronization. The synchronized payloads improve throughput (Figure A-2).

Dispatch Call Model

Dispatch calls are half-duplex and tend to be brief. Some sample information used to determine a dispatch call capacity on a iDEN system is summarized in Table A-1. Note Call Models vary.

Neighbor Cell List

The Neighbor Cell List is specific to each cell (sector or omni). The neighbor list is a set of logical numbers assigned to other cells that indicate potential handover candidates. The list identifies cells that are adjacent or close enough to take over control of the voice and data communication between the MS and the EBTS as the mobile moves around the network (Figure D-3). The MS uses the broadcast channel to scan the Neighbor Cell List and uses the radio link quality to select a new host cell. This is based on radio link quality (SQE and RSSI), and operator (software) set parameters. This assures the best possible radio link quality on a real-time basis. Figure D-3 Logical Neighbor Cell Listings
