Method and apparatus for coordinated multi-point transmission with negotiated quality of service

摘要

The present invention discloses a communication method, a device and a communication system. The technical solutions provided by the present invention include: a Base Station Router (BSR) and a service server. The BSR is configured to make a Mobile Station (MS) access a network, obtain information of multiple transmission paths from the service server during a process for the MS to apply to the service server for a service, and provide a communication service for the MS and the service server by using a multi-path transmission scheme. The service server, connected with the BSR, is configured to obtain information of QoS required by the service applied by the MS, determine the multiple transmission paths according to the information of the QoS, and communicate with the MS by using the multi-path transmission scheme.

1. A communication system, comprising:
a Base Station Router (BSR); a service server; wherein the BSR is configured to make a Mobile Station (MS) access a network, receive a service application message sent from the MS during a process for the MS to apply to the service server for a service, forward the service application message to the service server, and obtain information of multiple transmission paths from the service server to the MS, wherein the service application message comprising information of the service and information of Quality of Service (QoS) required by the service; wherein the service server, connected with the BSR, is configured to receive from the BSR the service application message, determine the multiple transmission paths according to the information of the QoS, and communicate with the MS through the multiple transmission paths; wherein each of the multiple transmission paths passes through a plurality of network elements, and wherein the BSR is further configured to obtain the information of the QoS required by the service applied by the MS, and provide a communication service for the MS and the service server by using a coordinated multi-point transmission scheme according to the information of the QoS, wherein the BSR is further configured to perform mobility management on the MS by using a distributed management mechanism; the service server is further configured to:
negotiate with the MS for lowering the QoS required by the service, when the service server is incapable of satisfying the QoS required by the service, to obtain information of the negotiated QoS;determine multiple transmission paths according to the information of the negotiated QoS and send information of the multiple transmission paths to the BSR that is determined according to the information of the negotiated QoS; andcommunicate with the MS through the multiple transmission paths that is determined according to the information of the negotiated QoS, and communicate with the MS using a coordinated multi-point transmission scheme determined according to the information of the negotiated QoS.
