Problems solved by technology

[0008] The shortcoming of the method of above-mentioned prior art is: do not consider the ability of different base stations and existing old version base station (multi-cell Iub multi-cell MBMS transmission bearer multiplexing function just introduces in WCDMA R7 version, the base station of previous version does not support this function), in the current design, the RNC does not know whether each base station supports MBMB transmission bearer multiplexing of multiple cells on the Iub interface
In practical applications, various base stations have different support capabilities. If the RNC requires a base station (including a base station with insufficient capacity or an existing old version of the base station) that does not have the ability to multiplex the MBMB transmission bearer on the Iub interface to carry out the transmission bearer Multiplexing will lead to failure of MBMB service data transmission, resulting in redundancy of signaling transmission on the Iub interface and waste of bandwidth

Embodiment Construction

[0030] The invention provides a method and system for transmitting MBMS service data on an Iub interface.

[0031] The main technical characteristics of the embodiments of the present invention are: the base station reports to the RNC whether the base station or each local cell / local cell group / cell of the base station supports the multi-cell MBMS transmission bearer multiplexing function information of the Iub interface. According to the information reported by the above-mentioned NodeB, the RNC determines whether the Iub interface of the NodeB adopts the mode of multi-cell transmission bearer multiplexing to transmit the MBMS service data.

[0032] The above information reported by the NodeB to the RNC may be carried by a RESOURCESTATUS INDICATION (resource status indication) message or an AUDIT REQUEST (checkout request) message sent to the RNC.

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings. Taking the RESOURC...

Abstract

The invention provides a method for transmitting the MBMS service data on an Iub interface and a system thereof. The method mainly comprises the steps as follows: a NodeB (base station) reports the information concerning whether the NodeB supports the MBMS (multimedia broadcast / multicast service) transmission bearing multiplexing function of the Iub interface to an RNC (radio base station controller); the RNC determines whether the MBMS service data is transmitted in the mode of multi-cell transmission bearing multiplexing on the Iub interface of the NodeB. The system mainly consists of the NodeB and the RNC. The utilization of the invention ensures that the RNC acquires the information concerning whether the base station and different sectors of the base support the MBMB transmission bearing multiplexing function on the Iub interface.

Description

technical field [0001] The invention relates to the field of wireless network communication, in particular to a method and system for transmitting MBMS service data on an Iub interface. Background technique [0002] At present, the research and application of digital TV broadcasting technology has achieved a lot of results, from satellite digital TV, cable digital TV, terrestrial digital TV to mobile video broadcasting, digital TV broadcasting technology has been widely used in many countries and regions, and achieved brought substantial social and economic benefits. [0003] Due to the combination of the characteristics of digital TV and mobile communication, mobile video broadcasting technology meets the needs of people to receive TV services anytime and anywhere. It has huge development potential and has received more and more attention from all parties. It may become the next mobile communication Focus business. For example, in order to realize the mobile video broadca...
