Embodiment Construction

[0054] 1) Node B logical model proposed by the present invention

[0055] Figure 5 shows the Node B logic model proposed by the present invention.

[0056] The Node B MBMS communication context corresponds to the resources necessary for the Node B to process MBMS services, and it contains relevant information for a certain MBMS service communication. The NBMC is created when the MBMS transmission channel is established, and will be deleted when the MBMS service ends. NBMC may include the following parameters: MBMS service identifier, cell list receiving the MBMS service, MBMS data port and physical layer parameters, etc.

[0057] The MBMS data port corresponds to a user plane bearer, and is used to transmit MBMS data on the Iub interface. There are one or more MBMS data terminals for each MBMS service;

[0058] The MBMS communication control port corresponds to a signaling bearer between RNC and Node B, and is used to control NBMC. There is one MBMS control port for each...

Abstract

A kind of Node B MBMS communication context (NBMC) is added to B logic model, corresponding to needed resources for Node B to treat a MBMS service, when building MBMS transmission channel, NBMC is created; a kind of MBMS data port is added to B logic model, corresponding a load supporting at user side for Iub interface to transfer MBMS data, one or more data ports are provided for each MBMS service; a kind of MBMS Control Port is added to B logic model, corresponding a signaling load supporting between RNC and Node B for controlling NBMC, each MBMS service has a MBMS control port.

Description

technical field [0001] The invention relates to a method for sharing multimedia broadcast and multicast services (hereinafter referred to as MBMS) at an Iub interface in a wideband code division multiple access (hereinafter referred to as WCDMA) mobile communication system. [0002] (MBMS is a new point-to-multipoint service in the third-generation mobile communication. It is clearly pointed out in the principles of its architecture design that the MBMS system should be able to effectively use the resources of the wireless network and the core network, and receive the same During business, a plurality of users should be able to share resource.And in the specification of current third generation mobile communication partnership project (hereinafter referred to as 3GPP), still do not have the method that realizes MBMS business sharing at Iub interface.The present invention proposes in Node B A new communication entity and the corresponding data port and control port effectively ...
