Abstract

A wireless communication terminal, which performs wireless communication with base stations using each of a first communication method and a second communication method and enables to be in an idle state with both methods, having a setting section that sets a suspend time for detecting an incoming call from the base station using the first communication method subsequent to completion of communication with the base station using the first communication method; and a determination section that determines a cause of the completion of communication with the base station, wherein the setting section sets the suspend time based on the cause of completion of communication determined by the determination section.

Claims

1. A wireless communication terminal, which performs wireless communication with base stations using each of a first communication method and a second communication method and enables to be in an idle state with both methods, comprising:

a setting section embodied on a microprocessor and configured for setting a suspend time for detecting an incoming call from the base station using the first communication method subsequent to completion of communication with the base station using the first communication method; and

a determination section embodied on a microprocessor and configured for determining a cause of the completion of communication with the base station, wherein

the setting section sets a time as the suspend time based on the cause of completion of communication determined by the determination section, and

the setting section sets the suspend time for zero except when the cause of the completion of communication is interruption of wireless communication.

2. The wireless communication terminal according to claim 1, wherein the setting section does not set the suspend time except when the cause of the completion of communication is interruption of wireless communication.

3. The wireless communication terminal according to claim 1 or 2, wherein the first communication method is a 1xEVDO system, and the second communication method is a cdma2000 1x system.

4. A wireless communication terminal control method embodied on a non-transitory computer-readable medium and executed on a microprocessor which performs wireless communication with base stations using each of a first communication method and a second communication method and enables to be in an idle state with both methods, the method comprising the steps of:

determining a cause of completion of communication with the base station using the first communication method; and

setting a time as a suspend time for detecting an incoming call from the base station using the first communication method subsequent to the completion of communication with the base station using the first communication method, based on the determined cause of the completion of communication,

wherein the suspend time is set for zero except when the cause of the completion of communication is interruption of wireless communication.

5. The wireless communication terminal control method according to claim 4, wherein the suspend time is not set except when the cause of completion of communication is interruption of wireless communication.

6. The wireless communication terminal control method according to claim 4 or 5, wherein the first communication method is a 1xEVDO system, and the second communication method is a cdma2000 1x system.
