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 field in the bearer multiplexing request message sent by the RNC to the NodeB is set to the Binding ID of the FACH used to transmit the M...

Abstract

A method for implementing Iub port bandwidth multiplexing, adding a group of NBAP signaling at the Iub port; setting up FACH channels for each cell, setting the required Iub port bandwidth for the FACH used to transmit MBMS services; RNC sending bearer multiplexing Request message to NodeB to inform the broadcast target of the data; NodeB saves the multiplexing relationship of the received message to the interface board, and sends a bearer multiplexing response message or failure message to RNC according to the received message; RNC receives the bearer of NodeB After multiplexing the response message, start sending MBMS service data to NodeB; NodeB broadcasts the data to the transmission channels of multiple cells according to the saved multiplexing relationship. The invention realizes the broadcasting of the data by the NodeB interface board, prevents the RNC from transmitting multiple identical data at the Iub port, achieves the purpose of multiple transmission channels multiplexing one bearer, and saves 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...
