<P>PROBLEM TO BE SOLVED: To prevent many position registration requests from taking place into a normal base station, resulting in increasing the load on the occurrence of a transmission fault of a notice signal in a base station. <P>SOLUTION: On the occurrence of a fault in a base station 20, the host device 10 transmits a position registration restriction signal d to the normal base station 30. The base station 30 multiplexes the restriction signal d on the notice signal f and transmits the resulting signal to each terminal 40. In each terminal 40 when it is in a standby state, a position registration timing management circuit 44 generates and transmits a position registration request k in a random timing after a lapse of a prescribed time. When each terminal 40 is in a call connection state or makes a new dialing operation, the terminal processes the operation with priority. Thus, the concentration of position registration requests onto the base station 30, resulting in the overload of the base station 30 is prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
