PROCESSING METHOD AND APPARATUS FOR Iu INTERFACE PARALLEL MULTIMEDIA BROADCAST MULTICAST SERVICE SESSION START-UP

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.
