Problems solved by technology

Solution A has the smallest system overhead, but the corresponding flexibility is also the lowest, and even some resources cannot be allocated in some MBMS overlapping areas, resulting in service failure or serious waste of resources; and solution A is in MBMS overlapping areas Due to the limitation of the configuration method, the system overhead may increase exponentially, making this method unable to be used normally in the MBMS overlapping area
Solution B uses the 32-bit bitmap method to maximize scheduling flexibility, but it is obvious that the 32-bit system overhead is the largest among all solutions, and the system information load brought to the system is also the largest

Embodiment Construction

[0049] The core idea of ​​the present invention is: the MBMS service resource allocation method can be composed of two or more resource allocation schemes, and the resource allocation schemes can be switched; distribution plan.

[0050] Specifically, the base station side selects an MBMS service resource allocation scheme that has low signaling overhead and can be allocated. The terminal side receives the corresponding MBMS resource allocation instruction according to the protocol, interprets the signaling content, and obtains the final instruction content.

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] The base station side can select an appropriate resource allocation scheme and perform switching according to whether overlap occurs, the degree of overlap, signaling overhead, allocation flexibility, and whether allocation can be realized. Such as figure 2 As shown, the embodi...

Abstract

The invention discloses a multimedia broadcast and multicast service MBMS resource allocating method, which consists of at least two resource allocating schemes; and a base station compares the resource allocating schemes, and selects a scheme which has smaller signaling overhead and can realize allocation to perform service resource allocation. The method effectively combines the advantages of several schemes, can ensure that the wireless frame-level allocation has the highest flexibility and minimum overhead, and also can ensure that the signaling overhead for resource allocation in an overlapped coverage area is minimized and the signaling overhead for resource allocation in a non-overlapped coverage area is also minimized.

Description

technical field [0001] The present invention relates to a Long Term Evolution (LTE for short) system, and in particular to a method for resource allocation of Multimedia Broadcast Multicast Service (MBMS for short) in a hybrid carrier system. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferences, TV broadcasts, video on demand, advertisements, online education, interactive games, etc. On the one hand, it satisfies the ever-increasing business demands of mobile users, and at the same time brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and de...
