Radio system and spectrum resource reconfiguration method thereof

摘要

Disclose is a radio system and a spectrum resource reconfiguration method thereof. The method comprises: a Reconfigurable Base Station (RBS) divides subordinate nodes into groups according to attributes of the subordinate nodes, and sends a reconfiguration command to a subordinate node in a designated group, and the RBS and the subordinate node execute reconfiguration of spectrum resources according to the reconfiguration command; or, the RBS executes reconfiguration of spectrum resources according to the reconfiguration command; and a subordinate User Equipment (UE) accessing to a reconfigured RBS after interruption. By means of the present disclosure, the reconfiguration of spectrum resources of a cognitive radio system can be realized.

1. A method for reconfiguring a spectrum resource of a radio system, wherein the method comprises:
transmitting, by a Reconfigurable Base Station (RBS), a reconfiguration command to a group of subordinate nodes; executing, by the RBS and the subordinate nodes, reconfiguration of spectrum resources according to the reconfiguration command; wherein the reconfiguration command is generated by a node of an upper layer of the RBS; receiving, by the RBS, the reconfiguration command from the node of the upper layer of the RBS, filtering and/or converting the received reconfiguration command, and sending the filtered and/or converted reconfiguration command to the subordinate node; wherein the group subordinate nodes are obtained by means of dividing, by the RBS, subordinate nodes into groups according to attributes of the subordinate nodes: applying the same reconfiguration strategy to subordinate nodes in the same group, and the same reconfiguration command accordingly: configuring, by the RBS, the same identifier for the subordinate nodes in the same group: finding, by the RBS, all subordinate nodes in the group according to the identifier.
