[0010] If the UE has received other non-MBMS services, the corresponding cell needs to allocate resources for the non-MBMS services after converging to the PL, so it will have a great impact on the allocation of PL cell resources. If the cell resources are congested, it may also affect other services. normal reception of

Embodiment Construction
[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0028] figure 2 A method for selecting a preferred frequency layer for a multimedia broadcast / multicast service according to the present invention is shown. Such as figure 2 As shown, the multimedia broadcast / multicast service preferred frequency layer selection method includes the following steps:
[0029] Step S202, for each frequency layer, calculate the total resource consumption of all user equipments in the CELL_DCH state that activate the multimedia broadcast / multicast service;
[0030] Step S204, comparing the total resource consumption of each frequency layer; and
[0031] In step S206, according to the comparison result, the frequency layer with the l...

The invention discloses a method for selecting the optimal frequency layer of a multimedia broadcasting and multicast service, and a device thereof, wherein, the method comprises the following steps that: step S102, as for each frequency layer, total resource consumption for activating all user equipment in a CELL_DCH state of the multimedia broadcasting and multicast service are calculated; stepS104, the total resource consumption of all frequency layers are compared; and step S106, according to comparison results, the frequency layer with the maximum total resource consumption is used as the optimal frequency layer. Therefore, the method of the invention reduces the shock to the existing system to the maximum extent while using a frequency layer converging technology to save radio resources, thus being beneficial for the stabilization of the system.
Description
technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for selecting a preferred frequency layer for a multimedia broadcast / multicast service. Background technique [0002] For example, in a Wideband Code Division Multiple Access (WCDMA) mobile communication system, Multimedia Broadcast / Multicast Service (MBMS) is a technology for sharing network resources to transmit data from one data source to multiple targets. In a traditional mobile network, a Cell Broadcast Service (CBS) allows low bit rate data to be sent to all users through a cell shared broadcast channel, which belongs to a message service. [0003] In R99, only the short message service (SMS) cell broadcast service uses CBS. In order to effectively utilize mobile network resources, 3GPP (Third Generation Partnership Project) proposed Multimedia Broadcast / Multicast Service (MBMS) in R6, which provides a point-to-multipoint service in which...
