Problems solved by technology

However, since the Criticality Diagnostics IE is not included in the MBMS RAB RELEASE message and MBMS RABRELEASE FAILURE message (see Figure 3(a) and Figure 3(b)), the processing of the CN can only interrupt the normal processing flow, which will inevitably cause The following problems, that is, cannot ignore the IE whose Assigned Criticality value is Ignore And Notify and continue normal processing, cannot directly reject the message flow containing the IE whose Assigned Criticality value is Reject, and cannot include error IE / in the response message IE GROUP information, so it does not meet the requirements of protocol processing

[0043] In a first embodiment according to the present invention, a processing method for an MBMS RAB release request is provided. The following will refer to Figure 4 To describe the first embodiment of the present invention, wherein, Figure 4 is a flowchart showing a release request processing method according to the first embodiment of the present invention.

[0044] Such as Figure 4 As shown, the release request processing method according to the first embodiment of the present invention includes the following steps: Step S402: the network side (CN) decodes the MBMS RAB release request message (first message) from the radio network controller (RNC), wherein , the decoded MBMS RAB release request message contains a specific information element, and the error diagnosis attribute of the specific information element is ignore and notify; step S404: the network side stores information related to the specific information element; step S406: if the network side Agree to rele...

[0048] In a second embodiment according to the present invention, a processing method for an MBMS RAB release request is provided. The following will refer to Figure 5 to describe the second embodiment of the present invention, wherein, Figure 5 is a flowchart showing a release request processing method according to the second embodiment of the present invention.

[0049] The difference between the second embodiment and the first embodiment lies in that the error diagnosis attribute of the specific information element contained in the MBMS RAB release request message (the first message) is reject, and other than that, it is roughly the same, therefore, the reference to the specific information element will be omitted. A detailed description of the details.

[0050] Such as Figure 5 As shown, the release request processing method according to the second embodiment of the present invention includes the following steps: Step S502: the network side (CN) decodes the MBMS RAB ...

Abstract

The present invention provides a processing method for MBMS RAB release request, comprising the following steps: first step, the network side decodes the first message from the radio network controller; second step, in the decoded first message When a specific information element is included, the network side stores information related to the specific information element; and in a third step, the network side generates a second message, wherein the second message carries an error diagnosis information element for indicating that the information related to the specific information element Information. The invention also provides a device for processing a release request. Through the above technical solution, the present invention achieves the following beneficial effects: the MBMS RAB release request can be normally processed according to the requirements of the protocol, that is, when there is an unknown or wrongly decoded IE in the MBMS RAB release request message received by the network side and its error When the diagnosis attribute is "ignore and notify" or "reject", the sending end can be notified of the error IE information in the corresponding response message, helping the system to quickly locate the problem.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to a release request processing method and device, which can be applied to such as mobile video broadcasting systems. Background technique [0002] After more than ten years of development, the research and application of digital TV broadcasting technology has achieved a lot of results, from satellite digital TV (represented by DVB-S, DVB-S2 in Europe, S-DMB in South Korea and Japan), cable digital TV (represented by DVB-C in Europe), terrestrial digital TV (represented by DVB-T in Europe, ATSC in the United States, IDSB-T in Japan, DMB-T in China, etc.) to mobile video broadcasting (represented in Europe DVB-H, Qualcomm's FLO as representatives), has been widely used in many countries and regions, and has achieved fruitful social and economic benefits. [0003] The mobile video broadcasting technology combining digital TV and mobile communication meets the needs o...
