Introduction APCO Project 25 applies to both conventional and trunked systems. The distinction between conventional and trunking systems may be

12、that trunking systems include a centralized controlling device which is used to assign channels to subscribers as service is demanded. This controlling device is absent in a conventional system. A large set of useful functions are defined for trunking systems, including but not limited to the functi

13、ons necessary for subscribers to request service and for the controller to grant service. Trunking also defines functions which may be applied to conventional systems, such as an Emergency Alarm. This document is intended to name those functions that are defined for trunking which may be applied to

14、conventional systems. 2. Scope This document defines the control messages of trunking for APCO Project 25 that may be applied to conventional systems. These control messages are extensions to the basic Common Air Interface. Conventional systems for APCO Project 25 are defined to be any non-trunked s

15、ystem which conforms to the standards and specifications of reference 11 or its subordinate documents, where a trunked system is defined to include a centralized controller that assigns requests for service by subscribers to specific radio channels. Conventional systems therefore do not have a contr

16、oller which assigns radio channels in the same sense as defined in reference 2. 3. Overview The following control messages of trunking systems are useful in some conventional systems. Those control messages for services that are listed as standard options in reference I are labeled accordingly. Emer

I The procedures for these messages generally follows the trunking procedures described in reference 4. The specific sections in reference 4 are given in Table 6-3. There are some differences for co

32、nventional systems, which abbreviate the given trunking procedures. The following specific differences are noted in Table 6-3. 1. The random access protocol for the trunking control channel is not followed, because there is no control channel. Instead, the channel access procedure given in reference

33、 6, section 8.1 shall be followed. This procedure is intended to follow a polite channel access procedure. In the particular case of the emergency alarm, an impolite channel access procedure may be followed which ignores the status symbols on the channel. repeating information, as described in refer

34、ence 6, section 7. Consequently, trunking procedures for the RFSS shall be ignored for conventional systems. 3. Many trunking procedures for subscriber radios are designed to terminate retransmissions if the subscriber radio hears the RFSS repeat a message, This is allowed for call alerts, status up

35、dates, etc. Since the RFSS does not take any responsibility for retransmissions by itself, the termination of retries by subscribers in response to a control message repeated by the RFSS shall not be followed in conventional systems. 4. A conventional RFSS does not contain any control elements, exce

36、pt for the possibility of a dispatch console. Consequently, the Deny Response (DENY-RSP) and Queued Response (QUE-RSP) messages defined for trunking do not apply, and are not necessary. 5. A conventional RFSS does not maintain any affiliation, registration, or authentication records. Consequently, p

37、rocedures that include affiliation, registration, or authentication can proceed without requesting or initiating these functions. roaming. Consequently, the extended addressing defined for many of the messages, which includes the WACN and System ID in the message, is 2. The RFSS in a conventional sy
