In a radio communication system wherein radio frequencies for communicating with a radio terminal are different in radio base stations, a table in which positional information, information on the frequency used for transmission/reception to/from the terminal, and a decision condition in a handoff operation are stored as to each base station is prepared in a base station controller beforehand. When the positional information is received from the radio terminal, the base station controller selects the base station being a handoff candidate, on the basis of the positional information of the radio terminal, the positional information of each base station and the decision condition of the handoff operation with reference to the table, and it transmits a handoff request message which contains the information on the frequency of the base station being the handoff candidate, to the radio terminal through the base station communicating with the radio terminal.
摘要:
A wireless communication system and its test method capable of executing a test of the wireless communication apparatus from a remote place by using a terminal generally used in wireless communication systems are implemented with a low-cost configuration and a simple procedure. A terminal obtained by installing a test AP on a general terminal that is used in general wireless communication systems and that can execute APs via a communication network is placed in a coverage area of a wireless communication apparatus. A maintenance center for the wireless communication system activates the terminal. The terminal executes the test AP and conducts communication with the maintenance center by using control signals and test signals for testing wireless communication system. A test is executed by measuring an actual communication state of the wireless communication system.

摘要:
A radio communication terminal, being used in a radio communication systems in which the transmission rate varies depending on radio wave conditions and communication statuses of other users, comprises a reception module which receives packets transmitted by a base station in an idle state of the radio communication terminal, a signal processing module which estimates a transmission rate available in communication based on the packets received by the reception module, and a display module which displays information indicating the transmission rate estimated by the signal processing module.
