Problems solved by technology

[0012] At this time, when resource allocation is performed according to the existing method, uniform resource allocation is performed without distinguishing SA. In the allocation mode, since the first 8 code channels have been allocated to the MBMS service area SA1 carrying the MBMS A service, it cannot SA1 is assigned to carry MBMS B service, and the last 8 code channels have been allocated to MBMS service area SA3 carrying MBMS A service, so it cannot be allocated to SA3 to carry MBMS B service. Allocation fails at all, greatly reducing the utilization of physical resources

Embodiment Construction

[0053] The resource allocation method for multimedia broadcast and multicast services and the radio network controller in the embodiments of the present invention group the SAs of multimedia broadcast and multicast services according to adjacent SAs, and then allocate resources according to the adjacent SAs, so as to improve the physical resource utilization.

[0054] Before describing the embodiments of the present invention in detail, the concepts involved in the embodiments of the present invention will be described in detail to facilitate a better understanding of the present invention.

[0055] Independent SA, the coverage area of ​​the independent SA does not overlap with the coverage area of ​​any other SA;

[0056] The set of adjacent SAs includes at least two SAs, and the coverage areas of the at least two SAs form a continuous and uninterrupted area through overlapping coverage areas between each other.

[0057] Such as figure 2 In the various situations shown, SA...

Abstract

The invention provides a resource distribution method of multimedia broadcast and multicast service and radio network controller, wherein, the method includes: receiving physical resource distribution request of multimedia broadcast and multicast services, the physical resource distribution request including carrying service regions and demand resource information; distributing the carrying service regions according to the adjacent relation to form a service region combination, wherein service region(s) included in each service region combination constitute an adjacent service region set, or is an independent service region, and the service region(s) in the carrying service region pertaining to a same adjacent service region are distributed to a service region set; Physical resource distribution is performed to the service region combination in order based on the resource status of the present practical physical resource pool and the demand resource information, all service regions ina service region combination has the same physical resource. The invention improves the success ratio of resource distribution and the utilization rate of the physical resource.

Description

technical field [0001] The invention relates to multimedia broadcast and multicast services, in particular to a resource allocation method and a wireless network controller for multimedia broadcast and multicast services. Background technique [0002] MBMS (Multimedia Broadcast / Multimedia Service Multimedia Broadcast and Multicast) technology is a very promising service in the 3G communication system. [0003] When the multimedia broadcast / multicast service is implemented, mobile terminal users receive broadcast digital audio and video content (such as TV) in the form of channels or channels on intelligent mobile terminals with operating systems and video functions. [0004] The wireless bearer mode of the MBMS service may be a PTM (Point to Multipoint, point-to-multipoint) mode and a PTP (Point to Point, point-to-point) mode. The PTM bearing mode of the MBMS service sends data to all UEs (User Equipment, User Equipment) that join the multicast service or are interested in ...
