Method and device for establishing MBMS wireless access carrier indication

Abstract

The invention discloses a processing method for establishing an MBMS wireless access bearing indication and a device thereof. The method mainly comprises the steps as follows: a message of establishing the MBMS RAB indication sent by an RNC is received and then the indication message is decoded; if the indication message is decoded successfully, a confirmation message of successful establishment is established and the message is coded and the confirmation message after being coded is transmitted to the RNC; if the indication message fails to be decoded, the IE / IE Group information to which anerror happens in the indication message is saved and the confirmation message of successful establishment is established, and the Criticality Diagnostics IE is contained in the message; the IE saves the information of the IE / IE Group to which an error happens and codes the confirmation message and transmits the message after being coded to the RNC. The use of the invention can allow the RNC to find out the cause of the error so as to avoid the similar condition from occurring when the message can not be decoded.

Description

technical field [0001] The invention relates to multimedia broadcast multicast service technology, in particular to a processing method and device for establishing a multicast and broadcast service (MBMS) wireless access bearer indication. Background technique [0002] The mobile video broadcast technology combining digital TV and mobile communication meets the needs of people to receive TV services anytime and anywhere due to the combination of the characteristics of digital TV and mobile communication. It has great development potential and is considered to be the next mobile communication The business with the most market has received more and more attention from all sides. In the existing broadband CDMA (Wideband Code-Division Multiple Access, WCDMA) multicast and broadcast service (Multimedia Broadcast / Multicast Service, MBMS) system, in Establish a radio access bearer (Radio Access Bearer, RAB) for each MBMS service between the radio resource controller (Radio Network ...

AI Technical Summary

Problems solved by technology

[0017] It can be seen from the above that in the MBMS RAB ESTABLISHMENT CONFIRMATION message, there is no Criticality Diagnostics IE indicating the information of the error IE / IE Group, so when the CN performs ASN.1 decoding on the received message, if it cannot be successfully decoded, That is, when an information element or information element group (IE / IE Group) that is unknown or should not appear is found, and the assigned emergency processing mode of the IE is Ignore and Notify, the error IE / IE Group cannot be included in the response message according to the requirements of the protocol. IE Group information, so the wrong IE / IE Group information cannot be reported, so that the cause of the problem cannot be found out, so similar situations cannot be avoided, resulting in incoherent communication
