Method, Entity, and System for Implementing Trunk Service

摘要

The present invention discloses a method, includes: receiving uplink control plane signaling or uplink control plane signaling and uplink user plane media data sent by a UE; performing, encapsulation and conversion on the uplink control plane signaling or the uplink control plane signaling and the uplink user plane media data, and sending the uplink control plane signaling or the uplink control plane signaling and the uplink user plane media data after the encapsulation and conversion to a TCF; receiving downlink control plane signaling or downlink control plane signaling and downlink user plane media data sent by the TCF; and performing encapsulation and conversion on the downlink control plane signaling or the downlink control plane signaling and the downlink user plane media data, and sending the downlink control plane signaling or the downlink control plane signaling and the downlink user plane media data after the encapsulation and conversion to the UE.

1. A method for implementing a trunk service, wherein the method comprises:
receiving, by an interworking function (IWF) entity, uplink signaling comprising at least uplink control plane signaling sent by a trunk user equipment (UE); performing, by the IWF entity, encapsulation and conversion on the uplink signaling to obtain encapsulated and converted uplink signaling; sending the encapsulated and converted uplink signaling to a trunk control function (TCF) entity; receiving, by the IWF entity, downlink signaling comprising at least downlink control plane signaling sent by the TCF entity; performing, by the IWF entity, encapsulation and conversion on the downlink signaling to obtain encapsulated and converted downlink signaling; and sending the encapsulated and converted downlink signaling to the UE.
