Abstract:
1. A method for processing Iu interface parallel multimedia broadcast multicast service session start-up, characterized in comprising the following steps: detecting after a Multimedia Broadcast Multicast Service (MBMS) session start-up message initiated by a Serving General Packet Radio Service Support Node (SGSN) has been received by a Radio Network Controller (RNC), whether other sessions of the same MBMS service have been established on the RNC; the RNC, when detecting that the other sessions of the same MBMS service have been established on the RNC, detecting whether the MBMS service area carried in the MBMS session start message interlaps or overlaps with that of the other MBMS sessions established between the RNC and the SGSN, or interlaps with that of the other MBMS session established between the RNC and other SGSNs, and performing the MBMS session start process according the the detecting result; and a determining response device of the RNC determining the MBMS service area in the MBMS session start message to be valid, processing MBMS session start flow, and returning MBMS session start response message or MBMS session start failure message to the SGSN according to the processing result when a detecting device of the RNC has detected that the MBMS service area carried in the MBMS session start message neither interlaps nor overlaps with that of other MBMS sessions established between the RNC and the SGSN, and do not interlap with that of the MBMS session established between the RNC and other SGSNs; and the determining response device of the RNC determining the MBMS service area in the MBMS session start message to be invalid and returning MBMS session start failure message to the SGSN when the detecting device of the RNC has detected that the MBMS service area carried in MBMS session start message interlaps or overlaps with that of other MBMS sessions established between the RNC and the SGSN, or interlaps with that of the MBMS session established between the RNC and other SGSNs.
