Embodiment —

[0082] The transformational embodiment is an example about transmitting IP packets on the uplink and downlink.

[0083] 1 When a plurality of wireless base stations receive signals at the same time

[0084] When a wireless base station (hereinafter referred to as wireless base station A) receives an outgoing call request from a mobile station, if it determines that the station does not have enough free wireless channels to accommodate the call communication, it will ask the surrounding wireless base station groups about the use of free wireless channels , and then receive reports about idle wireless channel conditions from surrounding wireless base station groups. Next, radio base station A selects a plurality of radio base stations (here, radio base stations B and C) that should be connected to the mobile station based on the report, and notifies the mobile station (for example, notification of identification information).

[0085]Then, the mobile station starts communicatin...

Abstract

A radio base station selection method according to the invention comprises: finding surrounding radio base station groups which may be communicated with a mobile station, selecting a radio base station selection which is communicated with the mobile station, wherein, the radio base station, when a necessary signal for comunicating with the mobile station is received, asks the surrounding radio base station groups knowed by the mobile station usage circumstance of a radio channel; the radio base station selects the radio base station which should be connected to the mobile station according to the radio channel usage circumstance report; and the radio base station notifies the information used for communication of the mobile station and the selected radio base station to the mobile station.

Description

technical field [0001] The present invention relates to a method and a system for selecting a wireless base station in a mobile communication system, in particular to a method and a system for selecting a wireless base station during outgoing and incoming calls and handover in the mobile communication system. [0002] In addition, the present invention also relates to a radio base station capable of selecting a radio base station according to the radio base station selection method. Background technique [0003] At present, as a cellular mobile communication system, a PDC (Personal Digital Cellular: Personal Digital Cellular) mobile communication system, a PHS (Personal Handy phone System: Personal Simple Phone System) mobile communication system, and the like are used. Conventionally, in such a mobile communication system, radio base station selection is performed in the following manner at the time of outgoing calls, incoming calls, and transfers. [0004] 1PHS system occ...
