Abstract

When UE receives MBMS service, there is non-MBMS service needed to send. UE sends 'service request' message in non-switch layer to SGSN. In forwarding the said 'service request' message, RNC checks whether UE receives MBMS service or not. If yes, then, UE receives shared Iu connection of a MBMS service, and does not launch procedure for building SCCP connection. Through shared Iu connection, RNC forwards the 'service request' message to SGSN. With the 'service request' message being received and accepted, SGSN returns the 'service request' to MS. Through UE, SGSN receives shared Iu connection of a MBMS service, and sends 'RAB allocation request' message to RNC for requesting to build RAB. Information elements: Permanent NAS UE Identity is added to current 'RAB allocation request' message in order to recognize UE in UTRAN and CN.

Description

technical field

[0001] The invention relates to a method for how to support the MBMS service to adopt shared signaling connection on the Iu interface in the process related to the RANAP message and the Iu interface in the mobile communication system. Background technique

[0002] Multimedia Broadcast and Multicast Service (hereinafter referred to as MBMS) is a new service being standardized by the Third Generation Partnership Project (hereinafter referred to as 3GPP). The standard under development is TR23.846, and its latest version is 1.0.0. The MBMS service is a one-way point-to-multipoint service. The biggest feature of this service is that it can effectively utilize wireless resources and network resources.

[0003] In order to better describe this patent, figure 1 The MBMS system structure is described. The MBMS network structure is based on the general packet radio service (GPRS) core network, and a new network unit is added. Below is the right figure 1 Description...
