Resource control system, method and base station and mobile station using the system, method

Abstract

An object of the present invention is to enable the improvement of Qos and efficient use of resources with regard to the entire system by performing resource control of an own cell in cooperation with that of peripheral cells. The present invention provides a resource control system used for packet communication between a mobile station and each of a first and a second base stations. The first base station includes the judgment unit for judging whether or not the Qos of a packet to be communicated with the mobile station is ensured in the packet communication with the mobile station, or judging whether or not the resources necessary for a packet to be communicated with the mobile station are secured; and the second base station interface for requesting the second base station to suppress the use of resources when the Qos is judged not to be ensured, or the necessary resources are judged not to be secured. The second base station includes a resource use suppression unit, which suppresses the use of resources for the packet communication with the mobile station in accordance with the request from the first base station.

Description

technical field [0001] The present invention relates to a resource control system and resource control method for data packet mobile communication, as well as a base station and a mobile station suitable for using the resource control system and resource control method. Background technique [0002] In data packet mobile communication using CDMA (Code Division Multiple Access), the capacity of the uplink wireless channel is determined by the maximum allowable receiving power of the base station, and the capacity of the downlink wireless channel is determined by the maximum transmission power of the base station . In packet mobile communication using CDMA, when implementing transmission power control (TPC), the received power of the base station (in the direction of the uplink link) or the transmission power of the base station (in the direction of the downlink link) is determined by the base station or the mobile The amount of interference a station receives.

AI Technical Summary

Problems solved by technology

[0003] However, in conventional packet mobile communication as mentioned above, when the amount of interference received by the base station or the mobile station increases, the total received power of the base station (in the uplink direction) exceeds its maximum allowable received power and the total transmitted power of the base station (downlink direction) the possibility of exceeding its maximum transmission power also increases

[0004] Therefore, there is a problem in that packet transmission between the base station and the mobile station fails or packet transmission becomes impossible, and causes packet drop or packet transmission delay

[0012] As described above, real-time data packets cannot be transmitted in microcell 1, and in microcell 2, after real-time data packets are transmitted, non-real-time data packets can also be transmitted. Low satisfaction of Qos and low utilization of resources in the entire service area
