Signaling tracking method, device and system in EMBMS

Abstract

A method, device and system for tracking a signalling in an EMBMS. The method comprises: after a network administrator of a core network in an EMBMS system issues a task to a network element with the highest system level, generating, by the network element, tracking signalling according to the received task, and sending the task to a network element of the next level through a protocol interface thereof by way of tracking signalling, thereby facilitating the issuing of the task, so that different signallings can be distinguished very conveniently by the method of task based signalling tracking, so as to avoid signalling confusion when a plurality of tasks are issued; and after the tracking signalling is sent to the network element of the next level, acquiring an interaction signalling over a channel through which the two network elements communicate, and when the interaction signalling and an identifier of the task are the same or have an indirect mapping relationship, reporting the interaction signalling to a task tracking and collection entity. Therefore, the present invention can overcome the deficiency that signallings of the same task are reported separately during single-network element signalling tracking, facilitating full-network element signalling tracking, network element cooperation and completion of a multicast service.

Description

technical field [0001] The present invention relates to the technical field of long term evolution mobile communication, in particular to a method, device and system for signaling tracking in EMBMS. Background technique [0002] LTE EMBMS (Long Term Evolution Evolved Multimedia Broadcast Multicast Service, Long Term Evolved Multimedia Broadcast and Multicast Service) is a broadcast technology that can support higher-speed multimedia data transmission, and can simultaneously broadcast to all users or a certain part of the network The user group sends high-speed multimedia data services. In the EMBMS system, the network elements MME (Mobility Management Entity, mobile management entity), MCE (MBMS Coordination Entity, multimedia broadcast and multicast service coordination entity), ENB (E-UTRAN NodeB, evolved base station) are involved in network construction and service During operation, a large number of signaling interactions are required to realize the coordinated operati...

AI Technical Summary

Problems solved by technology

This signaling tracking method has defects in analyzing and observing signaling at the system level. For example, the EMBMS system cannot analyze the correctness of signaling from the flow of all network elements, so as to obtain the cooperation and cooperat
