Embodiment Construction

[0052] The present invention defines a new direct information transmission message, and invents a construction method and a processing method of the message, so as to notify multiple TMGI channel type information between two RNCs through a "direct information transmission" process. In this way, the purpose of reducing the signaling transmission and processing process is achieved, and at the same time, the subsequent related processes caused by this process (such as the RRC process between the SRNC and the UE) and the purpose of reducing the complexity of system processing are achieved.

[0053] The Direct Information Transfer (Direct Information Transfer) message defined by the present invention is the same as Table 1 of the prior art, and the information element provided thereunder is the same as Table 2 of the prior art, but the MBMS channel type information therein The (MBMS Channel TypeInformation) information element is defined in the present invention as described in Tabl...

Abstract

The provided notifying method for MBMS channel type comprises: a first RNC constructs the direct message transmission message containing some TMGI and relative channel types, sends the message to a second RNC; the latter decodes the message to process the TMGI and relative channel type message. This invention is benefit to save channel resource.

Description

technical field [0001] The invention relates to the technical field of multimedia broadcast multicast service (MBMS), in particular to a method and system for notifying MBMS channel types between radio network controllers (RNC). Background technique [0002] Beginning with 3GPP R6, 3GPP defines a Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service), which is used to provide broadcast or multicast services to mobile users in a communication system. In the 3G radio access network UTRAN, the MBMS data from the core network will be carried on the downlink radio bearer (RB, Radio Bearer) for transmission. The logical channel used by the radio bearer corresponding to the MBMS may be a dedicated traffic channel (DTCH) or an MBMS point-to-multipoint traffic channel (MTCH, MBMS Point-to-Multipoint Traffic Channel). If it is DTCH, then DTCH will be mapped to transport channels such as dedicated channel (DCH), forward access channel (FACH), time-divisi...
