[0063] The first embodiment: when two adjacent cells apply for new MBMS service resources, and the new MBMS services of the two cells include both the same MBMS service and different MBMS services, how to coordinate the MBMS service resources of the two adjacent cells according to the present invention example.

[0064] Cell 1 and cell 2 are adjacent and belong to the same gateway. In this embodiment, it is assumed that the two cells are covered by the same base station. In cell 1, {1, 2, 3, 4} 4 MBMS services need to be added, and in cell 2, {1, 2, 5, 6} 4 MBMS services need to be added. refer to figure 2 , the process of the first embodiment includes the following steps:

[0065] Step 101, since cell 1 and cell 2 belong to the same base station, the base station sends a request message for applying for new MBMS service resources of cell 1 and cell 2 to the Co-ordinating Function through the gateway, and the MBMS service resource request message includes at least cell 1 T...

[0069] The second embodiment mainly describes an example of coordinating MBMS service resources of two adjacent cells according to the present invention when one cell temporarily suspends a certain MBMS service.

[0070] Cell 1 and cell 2 are adjacent and belong to the same gateway. Both cell 1 and cell 2 are transmitting MBMS services {1, 2, 3, 4}, and because there is no user terminal (UE) to receive MBMS services {1} in cell 2, in order to save air interface resources, the transmission needs to be temporarily stopped . refer to image 3 , the process of the second embodiment includes the following steps:

[0071] Step 201, the base station covering cell 2 sends a request message for temporarily suspending service {1} to the Co-ordinating Function through the gateway, and the MBMS service resource request message includes at least the ID of the temporarily suspended MBMS service.

[0072] In step 202, after receiving the service resource request message, the Co-ordinating...

[0075] The third embodiment: mainly describes an example of coordinating MBMS service resources of two adjacent cells according to the present invention when a new MBMS service is added in a cell.

[0076] Cell 1 and cell 2 are adjacent and belong to the same gateway. MBMS services {1, 2, 3, 4} are being transmitted in cell 1 and cell 2, and a new MBMS service {7} is added in cell 1 at this time. refer to Figure 4 , the process of the third embodiment includes the following steps:

[0077] Step 301, the base station covering cell 1 sends a request message for applying for a new MBMS service resource to the Co-ordinating Function through the gateway, and the MBMS service resource request message includes at least the identifier of the new MBMS service.

[0078] Step 302, the Co-ordinating Function obtains the resource coordination result according to whether there is the same MBMS service as the new MBMS of the cell 1 in the cell 2, that is, if there is the same service in t...

Abstract

The invention discloses a method for coordinating MBMS service resources in adjacent cells. The method includes the following steps: A. A base station covering a first cell sends an MBMS service resource request message to a first coordination and cooperation entity corresponding to the gateway through its own gateway; B. The first coordination and cooperation entity will return the resource coordination result obtained according to the resource conditions of the first cell and the adjacent second cell to the base station covering the first cell through a response message; C. The base station covering the first cell will adjust according to the response message MBMS service resources of the first cell. The present invention utilizes information interaction between the base station covering the adjacent cell and the coordination and cooperation entity corresponding to the gateway to which it belongs, thereby adjusting the MBMS service resources of the adjacent cell, so that the same resource is used to transmit the same MBMS service in the adjacent cell, Therefore, the interference problem existing when performing air interface combination at the edge of adjacent cells is solved.

Description

technical field [0001] The invention relates to the field of multi-carrier technology, in particular to a method and system for coordinating multimedia broadcast / multicast service resources of adjacent cells. Background technique [0002] Since the 1990s, multi-carrier technology has become a hot technology in broadband wireless communication. Its basic idea is to divide a broadband carrier into multiple sub-carriers and transmit data on multiple sub-carriers simultaneously. In most system applications, the width of the subcarrier is smaller than the coherent bandwidth of the channel, so that on the frequency selective channel, the fading on each subcarrier is flat fading, thereby reducing the crosstalk between symbols, and does not require complicated channel equalization. Suitable for high-speed data transmission. [0003] Orthogonal Frequency Division Multiplexing (OFDM) technology is a representative technology among multi-carrier technologies, which divides a given cha...
