Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] like image 3 In the shown mobile relay application scenario, 7 cells are identified by identifiers 1 to 7, and each cell has its own eNode B. The bus equipped with a mobile relay is currently under the service of cell 1, and the direction of movement can be to any cell, and it is assumed to move to cell 4 here. With respect to the mobile relay, at this time the eNode B of cell 1 is the source eNode B, and the eNode B of cell 4 is the target eNode B. When the relay is handed over from the source eNodeB to the target eNode B, the backhaul link is replaced first, and then the UE services accessed by the relay are matched from the access link to the backhaul link.

[0033] It is assumed that the mobile relay has access to multiple UEs. Each UE ma...

Abstract

The invention discloses a business matching system and method for an LTE-Advanced mobile relay access link and a return link. The system comprises a timing start module which is used for the business matching of the mobile relay MR_UE timing start access link and the return link, a business classification statistics module which is used for the classification statistics of MR_eNode B, UE(user Equipment)access number, operation queue and total volume of business of the mobile relay as well as determining the volume of business of the distributed return link resources, a resource statistics module which is used for the statistics of the return link resources of the MR_UE of the mobile relay, a business bypass module which is used for determining can-be-matched businesses of the access link and the return link, a business and resource matching module which is used for mapping the UE businesses which is available for the matching of the access link and the return link to transmission resources, and a matching feedback module which is used for sending matching feedback to the business classification statistics module and the resource statistics module. The business matching system and method for the LTE-Advanced mobile relay access link and the return link ensures the quality of QoS service of data transmission between UE and eNode B, after the return link is replaced.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a service matching system and method for an LTE-Advanced mobile relay access link and a backhaul link. Background technique [0002] LTE-Advanced is an evolved version of LTE, which requires a peak downlink rate of 1Gbps and an uplink rate of 500Mbps under a bandwidth of 100MHz. Since LTE-Advanced uses higher frequency band resources, the coverage area of ​​the cell becomes smaller and the attenuation loss is serious. If the above-mentioned problems are simply solved by increasing the density of base stations, it will bring about problems of increased costs and deployment difficulties for operators. For this reason, 3GPP has introduced relay (relay) technology in LTE-Advanced. After the introduction of the relay node (RN, relay node), the direct link (Direct Link) is replaced by the Backhaul Link (Backhaul Link) and the Access Link (Access Link) between...
