Method for user device to receive service data and stop transmitting service data in network

Abstract

The present invention discloses a method by which UE receives downloaded service data. UE receives the service data of the current service in the current sub-zone. The method includes: the network side sends UE the current service information in the sub-zone adjacent to the current sub-zone; according to the received current service information in the sub-zone adjacent to the current sub-zone, UE determines the adjacent sub-zone from which UE itself need receive the service data, and further receive the service data from the determined adjacent sub-zone. The present invention further discloses a method by which the network side stops sending downloaded service data. UE in the current sub-zone and UE in the sub-zone adjacent to the current sub-zone receive the service data sent by the current sub-zone. The method includes: if the network side determines that the number of UE receiving the service data in the current sub-zone is zero, and further determines no UE in the other sub-zones receiving the service data of the current sub-zone, then the network side stops sending the service data in the current sub-zone. According to the methods disclosed in the present invention, service interruption or loss of service data can be avoided in the process of reelecting sub-zones.

Description

technical field [0001] The invention relates to multicast technology, in particular to a method for user equipment to receive downlink service data and a network side to stop sending downlink service data. Background technique [0002] In the existing 3GPP R99 and R4 protocol networks, various services are provided for users, especially various data services can be provided for users, which meets various needs of users. Such as watching news, sports games and other streaming media services on mobile phones. These streaming media services have been realized through multicasting at present. [0003] This text takes the Cell Multicast (CMB) service as an example to give the method of the present invention. The CMB service is a multicast service carried on a Secondary Common Control Physical Channel (SCCPCH). A user equipment (UE) receives service data of a CMB service in a CELL-FACH state. The specific implementation process of the CMB service is as follows. [0004] The C...

Problems solved by technology

[0006] However, at present, a UE can only receive service data from the current cell where it is located, so when the UE is reselected in a cell, it usually leads to service interruption or loss of service data, which affects the user experience; moreover, in order to ensure The quality of the service data received by each UE is to improve the coverage of the cell. The SCCPCH carrying the CMB service will have a high transmission power, which will not only occupy a large amount of power resources, but also cause serious interference to other services of the network.
