When a strength of an electric field for receiving wireless in downlink is equal to or smaller than a predetermined strength, the mobile communication terminal device 105 transmits a retrieval request to the retrieval server 102 through the first wireless station 103 to cause the retrieval server to start selecting a new wireless station, changes at least one of profiles (UTP) for transmitting wireless in uplink, and notifies the first wireless station 103 of the changed profile(s). The first wireless station 103 changes a profile or profiles (URP) for receiving wireless in uplink, corresponding to the changed profile(s) (UTP) for transmitting wireless in uplink, received from the mobile wireless terminal device, changes at least one of profiles (DTP) for transmitting wireless in downlink, and notifies the mobile wireless terminal device of the changed profile(s) (DTP) for transmitting wireless in downlink. |
