METHOD, DEVICE, AND SYSTEM FOR IMPLEMENTING RELAY SELECTION

摘要

Disclosed is a network topology information server for use in implementing a relay selection. The network topology information server holds the network topology information and the operator policy information, and comprises a relay service unit. The relay service unit comprises a relay selection module and/or a relay sequencing module. Also disclosed are a system and a method for use in implementing a relay selection. In the present invention, by an expansion of the features of an existing network topology information server, the network topology information server is allowed to support a feature of relay node preferential selection, and to provide a corresponding interface. The utilization rate of the network topology information and the operator policy information are increased greatly, and the operational load and the data maintenance load on a relay management entity are reduced greatly, and with the employment of the network topology information updated in real-time, the work efficiency of the relay management entity is increased effectively, and the accuracy of relay selection is ensured.
