Set up method and its system for broadcast multi-cast service transmission mode

Abstract

This invention discloses a method for setting broadcast multicast service transmission mode and its system, in which, when calculating UE receiving the assigned broadcast multicast service, it only calculates the UE numbers with said local area as the optimum one to determine the transmission mode of the service in such area so as to avoid the influence generated from the statistic to UE of non-optimum areas in the connection with them during the process of soft switch, in which, the statistic to UE numbers is done by CRNC of the area, when it is taken as the DRNC of UE of the area, the DRNC gets the optimum area information of said UE from the SRNC, when the optimum area of said UE is changed, its SRNC informs the change to the original and the new optimum areas.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to broadcast multicast technology. Background technique [0002] After decades of rapid development, mobile communication has benefited more and more people, but the services it provides are still mainly telephone and messaging. With the rapid development of the Internet (Internet), a large number of mobile multimedia services have emerged, some of which require multiple User Equipment ("UE") to receive the same data at the same time, such as video on demand, television broadcasting, video conferencing , online education, interactive games, etc., can be implemented on the wired network by using Internet Protocol (Internet Protocol, referred to as "IP") multicast and broadcast technology. However, because the specific network structure, functional entity and wireless interface of the mobile communication network are different from the wired communication IP network, and compare...

Problems solved by technology

[0013] In practical application, the existing technology has the following problems: the number of UEs is counted according to the existing statistical method, and the transmission mode of the MBMS service is determined, which is prone to misjudgment, and unnecessary public transmission channels are established, resulting in waste of resources

However, since the UE determines the receiving mode of the UE according to the transmission mode of the optimal cell, cell 1 and cell 3 still use the PTP mode, so both UE1 and UE2 use the PTP mode to receive, and the link B in the cell 2 will not be deleted and C (cell 2 cannot forcibly delete these links, otherwise UE1 and UE2 will cause severe uplink interference to cell 2), and there is no UE in cell 2 with cell 2 as the optimal cell, so the public link established by cell 2 The transmission channel is not received by the UE at all, which is a waste of resources
