This document extends the Inter-RF Subsystem Interface (ISSI)
\nMessages and Procedures [102BACA]<\/strong> to support the
\nP25 Packet Data Service [102BAEB]<\/strong> over the ISSI
\namong Radio Frequency Subsystems (RFSSs) within a given Project 25
\n(P25) system and across P25 systems.<\/p>\n

[102BAEB]<\/strong> defines the P25 Internet Protocol
\n(IP) packet data communications bearer services in three Packet
\nData Services configurations:<\/p>\n

\u2022 Radio to Fixed Network Equipment (FNE) Packet Data Bearer
\nService (FNE Data)<\/p>\n

\u2022 Radio to Radio Data Bearer Service (Repeated Data)<\/p>\n

\u2022 Radio to Radio Packet Data Bearer Service (Direct Data)<\/p>\n

This document specifies ISSI support for FNE Data, as only this
\nPacket Data Services configuration may be extended to involve
\nmultiple RFSSs, and therefore P25 Packet Data Service over the
\nISSI.<\/p>\n

As such, this document defines the ISSI messages and procedures
\nto support P25 packet data communications among packet data capable
\nP25 digital radio units and P25 FNE data end systems (ESs) that
\nspan multiple RFSSs, across the A, Um, G, and Ed interfaces.
\nSpecifically, the following P25 packet data functions are
\nsupported:<\/p>\n

\u2022 Mobility management of packet data capable SUs<\/p>\n

\u2022 IP addressing for roaming Subscriber Unit (SU) and associated
\nMobile Data Peripheral s (MDPs).<\/p>\n

\u2022 Routing of IP datagrams to and from roaming SU and associated
\nMDPs.<\/p>\n

In certain scenarios, the Serving RFSS must determine an SU's
\nHome RFSS ID and unique IP address. This is done based on the WACN
\nID and System ID of the SUID as sent by the SU in the Unit
\nRegistration Request (U_REG_REQ in [102AABC]<\/strong>)
\nduring registration. The process by which the Serving RFSS obtains
\nthis information is implementation-dependent, and therefore not
\ndocumented in this or other ISSI standards.<\/p>\n

Conceptual models that define primitives and states may be
\nutilized to describe TIA-102 interface protocols. The primitive
\nexchanges and state transitions described by these models are to
\nillustrate a conceptual design for a stack that implements the
\nprotocol and are informative. The boundaries defined by conceptual
\nmodels are internal protocol stack layer boundaries defined to
\nclarify the protocol description and are not testable
\nboundaries.<\/p>\n

The Packet Data ISSI supports IPv4 and future migration to
\nIPv6.<\/p>\n

This document specifies P25 Packet Data ISSI for trunked, not
\nconventional, P25 systems.<\/p>\n

In this ISSI release for P25 Packet Data, data packets are
\nrouted from the source SU to the destination SU through the
\ncustomer network. Routing of data packets between the source SU
\nHome RFSS and the destination SU Home RFSS over the ISSI could be
\nspecified in a future release if required.<\/p>\n

In this Release of P25 Packet Data ISSI, rerouting of
\nundelivered IP datagrams from a Serving RFSS to the Home RFSS is
\nnot supported.<\/p>\n","protected":false},"excerpt":{"rendered":"
