Problems solved by technology

[0013] In the prior art, there is no mention of how to deal with the situation where all the nodes in the downstream node do not respond correctly. If this situation is not dealt with, the data resources related to the business are still stored in the node, and the upstream node will continue to Sending data packets, resulting in waste of resources

Embodiment Construction

[0029] As shown in Figure 3, the present invention proposes a method for canceling the MBMS service in the multicast service for the failure of all downstream nodes in the MBMS session start process. Release related resources. Include the following steps:

[0030] Step 301, the upstream node initiates a session start request message to all downstream nodes in the MBMS context;

[0031] Step 302, the node creates or updates the MBMS context, and then sends back a session start response message upstream;

[0032] Step 303, the node initiates a session start request message to all downstream nodes in the MBMS context;

[0033] Step 304, the local node waits for the session start response message of the downstream node. If a correct response from any downstream node is received within the set time, the process ends normally; if no response from any downstream node (including no response and failure response) is received within the set time, enter the following Exception handli...

Abstract

An exception handling method in mobile multi-broadcasting broadcast service is disclosed, after the present node receives the requirement messages for starting dialog from upper node, it builds and refreshes the context of multi-broadcasting broadcast service, and then sends the response message for starting dialog to upper node, and sends the requirement messages for starting dialog to lower node of the context of multi-broadcasting broadcast service, thereinto, when the present node sends requirement messages for starting dialog to lower node, it includes following steps: (1) the present node judges whether all lower nodes can not realize the multi-broadcasting broadcast service; (2) when present node knows that all lower nodes can not realize the multi-broadcasting broadcast service, the present node initiates the log-on flow to upper node. The invention provides a method for fast releasing the system source and loading bandwidth when all flows of starting dialog of lower nodes are failed based on present multi-broadcasting broadcast service, and it can avoid the waste of system source and bandwidth.

Description

technical field [0001] The invention relates to an abnormal processing method of a mobile multicast broadcast service (MBMS: Multimedia Broadcast / Multicast Service). Background technique [0002] In order to effectively utilize mobile network resources, mobile multicast and broadcast services provide a point-to-multipoint service in which a data source sends data to multiple users in the mobile network, realize network resource sharing, and improve network resource utilization, especially the air interface interface resource. MBMS provides two modes: broadcast mode and multicast mode. MBMS can not only realize plain text low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services. The multicast and broadcast service MBMS is based on WCDMA / GSM packet network. By adding some new functional entities, For example, the broadcast multicast service center BMSC adds MBMS functions to existing functional entities in the packe...
