Problems solved by technology

[0019] In different paging scenarios, due to the configuration of different numbers of paging subframes, the MBSFN Subframe will be different, and the resource coordination between the MCE network element and the eNode B network element is relatively difficult, and the present invention is proposed. To this end, the present invention aims to provide an acquisition / configuration method and an acquisition device for multicast / broadcast subframes on a single frequency network, so as to solve at least one of the above-mentioned problems

Abstract

The invention discloses a method for acquiring / allocating multicast / broadcast subframes on single frequency network and an acquiring device thereof, wherein the method comprises the following steps that: an allocation rule for the multicast / broadcast MBSFN subframes on the single frequency network is preset, and subframes numbered as 4 and 9 are not allocated as MBSFN sub-frames; user equipment acquires a system broadcast message from a base station, wherein the system broadcast message carries the allocation information of the MBSFN subframes; and the user equipment determines subframes allocated as MBSFN subframes according to the allocation rule and the allocation information of the MBSFN subframes.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for acquiring / configuring a multicast / broadcast over Single Frequency Network (MBSFN for short) subframe. Background technique [0002] At present, in order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) proposed a multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, referred to as MBMS), MBMS is provided in the mobile network A point-to-multipoint service in which one data source sends data to multiple users can realize the sharing of network resources and improve the utilization rate of network resources, especially air interface resources. [0003] As mentioned above, MBMS is a technology that shares network resources to transmit data from one data source to multiple destinations. The MBMS provided by 3GPP can not only realize plai...
