This Telecommunications

The media used to provide these services consists of radio channels typically used for Advanced Mobile Phone System (AMPS) cellular service. o. 1 Document S
39、tructure This Telecommunications Systems Bulletin is published as a series of Parts. Each Part contains information pertaining to one aspect of the system. The functional structure of this TSB is as follows: o Part 1000 to Part 1999-Guidelines for Service Providers These Parts are informative and di

41、ervice Provider issues (such as an interoperability test plan overview and parameter configuration). Part 1000 contains the detailed listing of all Parts of this TSB. Part 2000 to Part 2999-Guidelines for Manufacturers of CDPD equipment These Parts are informative and.discuss such concerns as CDPD-s
42、pecific entities (such as Mobile End Systems (M-ESs), Mobile Data Base Stations (MDBSs) and Mobile Data Intermediate Systems (MD-ISS), external interfaces (such as that between the Subscriber Unit (SU) and the Subscriber Identity Module (SIM) and multicasts from the perspective of each of the partic
43、ipating entities. Part 3000 to Part 3999-Guidelines for the CDPD Network Information Center (NIC). These Parts are informative and describe the issues and procedures which must be addressed by an agency serving as a NIC on behalf of the CDPD community. o o 1022-iV Introduction TlAEIAITCB-87-1 O22 -
44、PART 1022 Parameter Configuration Guidelines 1 Introduction 2 The purpose of this Part is to recommend settings for many of the configurable parameters of CDPD. It should be noted that this Part constitutes a recommendation but not a requirement for CDPD Service Providers. Because it is a recommenda
45、tion, this Part does not purport to cover all configurable parameters. Physical Layer 2.1 This Section discusses CDPD Physical Layer parameters. Max-C hannel-Time If the RF channel is shared with other cellular transmissions, then the MDBS shall relinquish the RF channel after a period of time. This
46、 time period is defined as the MAX-CHANNEL-TIME. The MAX-CHANNEL-TIME is defined in IS-732-401. .- 1022-1 TWEIAlTSB-87-1022 Parameter Configuration Guidelines 2.1.1 Configuration The default MAX-CHANNEL-TIME is 1 minute. The MAX-CHANNEL-TIME must be set to a value that operates in concert with the u
47、nderlying cellular voice infrastructure. 3 Medium Access Control 3.1 This Section discusses CDPD MAC protocol parameters. Mi n-l d le-T i me 3.1.1 3.2 The CDPD Airlink is a shared resource where multiple M-ESs contend for reverse channel capacity. To prevent any M-ES from blocking other M-ESs attemp
48、ting to access the CDPD channel, the Medium Access Control mechanism prevents any single M-ES from continuously transmitting on the reverse channel. This is accomplished through the definition of the DSMA state machine procedures and the MIN-IDLE-TIME and MAX-BLOCKS parameters (see Section 3.2). The
49、 MIN-IDE-TIME defines the length of time, in microslots, where an M-ES must wait after entering the Idle state before it is allowed to transmit on the reverse channel. The MIN-IDLETIME parameter is defined in IS-732-402. By the MAC protocol definition, at the end of each transmission, the M-ES must cease transmission and wait a minimum of seven microslots in the Decode Wait state before entering the Idle state. This means that the MIN-IDLE-TIME is the number of microslots an M-ES must remain quiet in addition to the mandatory seven microslots. Configuration The default
