Abstract
A mobile station for a CDMA communication system which comprises a transmitting section that transmits a location registration request signal to a base station, and a receiving section that receives an acknowledge signal transmitted from the base station after the location registration request signal from the transmitting section is received by the base station. A control section prohibits the power supply to the receiving section for a predetermined period of time if the acknowledge signal from the base station is not received within a predetermined period of time after the location registration request signal has been transmitted.
Claims17
A mobile station configured to perform a location registration process via a base station connected to a communication system, comprising:
- a transmitter configured to transmit a location registration request signal to a base station being acquired by the mobile station;
- a receiver configured to receive an acknowledge signal transmitted, in response to the location registration request signal, from the base station;
- and
- a controller configured to disable the receiver by controlling on-off of a switch provided between a power supply and the receiver and to disable the transmitter for a first time period when the receiver does not receive the acknowledge signal within a second time period of the transmission of the location registration request signal, and configured to enable the receiver and to enable transmission of the location registration request signal to the base station when the first time period elapses.
A mobile station configured to perform a location registration process via a base station connected to a communication system, comprising:
- a transmitter configured to transmit a location registration request signal to a base station being acquired by the mobile station;
- a receiver configured to receive an acknowledge signal transmitted, in response to the location registration request signal, from the base station;
- a controller configured to disable the receiver and the transmitter for a first time period when the receiver does not receive the acknowledge signal within a second time period of the transmission of the location registration request signal, and configured to enable the receiver and to enable transmission of the location registration request signal to the base station when the first time period elapses;
- and
- means for acquiring a second base station when the receiver does not receive the acknowledge signal within a third time period of the transmission of the location registration request signal;
- wherein the transmitter transmits another location registration request signal to the acquired second base station and the receiver receives another acknowledge signal transmitted, in response to the another location registration request signal, from the acquired second base station.
A mobile station configured to perform a location registration process via a base station connected to a communication system, comprising:
- a transmitter configured to transmit a location registration request signal to a base station being acquired by the mobile station;
- a receiver configured to receive an acknowledge signal transmitted, in response to the location registration request signal, from the base station;
- and
- a controller configured to disable the receiver by controlling on-off of a switch provided between a power supply and the receiver for a first time period when the receiver does not receive the acknowledge signal within a second time period of the transmission of the location registration request signal, and configured to enable the receiver and to enable transmission of the location registration request signal to the base station when the first time period elapses.
