TIA Asks for Input, Help on P25 Standards Documents
Wednesday, October 09, 2019 | Comments

The Telecommunications Industry Association (TIA) TR-8.5 engineering committee on signaling and data transmission issued a call for interest on two documents in the Project 25 (P25) standards suite.

The TIA-102.BAEB-C titled IP Data Bearer Service Specification specifies the following set of IP convergence protocols for the conveyance of IPv4 datagrams over the Common Air Interface (CAI): Simple CAI Encapsulation Protocol (SCEP) and Subnetwork Dependent Convergence Protocol (SNDCP) versions 1 through 3.

The TIA-102.BAJB-B titled Tier 1 Location Services Specification provides a simple SU-to-SU interface for the direct data and repeated data configurations. This service uses a dedicated service access point over the CAI to transport location information formatted as described in National Marine Electronics Association (NMEA) 0183, a commonly used location protocol.

This service is appropriate for real-time field incident applications where the Location Service Host is resident on a portable device. It does not provide a mechanism to provide location information to a host device on a fixed network and does not support more advanced configuration of triggering and reporting.

Stakeholders may include but are not limited to P25 and private LMR.
