Embodiment Construction

[0014] If the RNC has an MBMS service to broadcast to multiple cells, it can be implemented through the following steps:

[0015] Step 1: set up the FACH channel for each sub-district, only the FACH that is used to transmit the MBMS service sets up the required Iub port bandwidth when setting up, and the bandwidth of other FACHs is set to 0. Node synchronization and transport channel synchronization are performed separately on each FACH.

[0016] Step 2: The RNC sends a bearer multiplexing request message to the NodeB through the Iub port, and informs the interface board of the NodeB which transmission channel data is to be broadcast to which transmission channels. The bearer multiplexing request message is a message added by the present invention, see Table 1. The table format follows the Iub port NBAP protocol format. The main binding ID (Main Binding ID) field in the bearer multiplexing request message that RNC sends to NodeB is set as the binding ID (Binding ID) of the F...

Abstract

The invention relates to a realizing method for the multiplexing uses of an Iub port bandwidth. A group of NBAP signaling is added in the Iub port and a FACH channel is established for each district. The FACH used to transfer MBMS operations is set with a needed Iub port bandwidth and RNC sends out a load multiplexing request message to NodeB and informs the data broadcast target; NodeB saves thereceived message multiplexing relationship to an interface board and sends a load multiplexing response message or failed message to RNC according to the situation of the received message; RNC beginsto send out MBMS operation data to NodeB after receiving the load multiplexing response message of NodeB; NodeB broadcasts the data to the transmission channel of multi-districts according to the saved multiplexing relationship. The invention has realized the broadcast to data by NodeB interface board, avoided RNC from transferring a plurality of identical data at the Iub port, reached the goal of multiplexing use one load by a plurality of transmission channels and saved bandwidth.

Description

technical field [0001] The invention relates to the field of WCDMA, in particular to the bandwidth multiplexing of the Iub port on the UTRAN side. Background technique [0002] 3GPP is in constant evolution and changes, constantly introducing new requirements to achieve low cost and high performance. MBMS (Multimedia Broadcast / Multicast Service) was introduced in 3GPP R6. MBMS can broadcast the operator's service content to all users in the cell, which improves the operator's service efficiency. Operators attach great importance to this function. The operator's service content is transmitted from the RNC to the NodeB through the Iub interface, and then the NodeB transmits it in the cell. With the increase of service content, the transmission bandwidth of the Iub port also increases exponentially. Assuming that the operator has a 256KB service that needs to be broadcast to n cells, according to the traditional mode, RNC repeats the transmission to n cells, so that (n*256) K...
