Inter-RF Subsystem Interface Messages and Procedures for TDMA Extensions, TIA-102.BACA-B (Nov 2012)
(Describes the architecture, protocol suite, messages, parameters, state models, and procedures to support the following services among RFSSs over the ISSI. Voice services: group voice service for both confirmed and unconfirmed group calls, SU-to-SU voice service for both direct calls and calls requiring prior RF availability check. Mobility management functions: mobile SU registration, mobile SU tracking, group affiliation by mobile SUs and consoles, group tracking, authentication credential distribution, SNDCP Context registration. Optional ISSI support functions: RFSS service capability polling.)
