Abstract: An updating method and device for an Iu interface supported parallel Multimedia Broadcast Multicast Service session are provided. The method includes: step 1, receiving the MBMS session updating message of the SGSN by the RNC; step 2, detecting whether the modified MBMS SA of the MBMS session and the MBMS SA of other sessions of the same service overlaps with each other or not; and step 3, performing the updating operation for the Multimedia Broadcast Multicast service session according to the detecting result.

Abstract: The present invention provides a method and an apparatus for processing Iu interface parallel multimedia broadcast multicast service session start-up, wherein the method comprises: after receiving a MBMS session start message sent by SGSN, RNC detects whether other sessions of a same MBMS service have been established; and when the other sessions of the same MBMS service are determined to have been established in the RNC, the RNC detects whether the MBMS service area carried in the MBMS session start message and that of the other MBMS sessions established between the RNC and the SGSN intersect or overlap or whether the MBMS service area carried in the MBMS session start message and that of the MBMS session established between the RNC and other SGSNs intersect, and processing on multimedia broadcast multicast service session start-up is performed according to the detecting result.

Abstract: A method for obtaining the MBMS supporting ability of a cell is disclosed. The method concludes: step 1 in which RNC transmits an audit request message to Node B; step 2, the Node B returns an audit response message containing the MBMS supporting ability information of the cell to the RNC. With the present invention, the RNC can obtain the MBMS supporting ability information of the cell, and obtain the MBMS supporting ability changing information of the cell in real time and correctly.
