Communication terminal and communication method thereof
First Claim
1. A communication terminal, comprising:
- a radio control section which performs radio communications conforming to a communication system for establishing a communication session by sending a parameter used for communications to a network, and performing a re-establishment processing of the communication session in response to the communication session being released so as to keep the communication session established regardless of whether or not information to be communicated exists,wherein when the radio control section releases the communication session based on a power-off processing of the communication terminal, the radio control section maintains the communication session released without performing the re-establishment processing of the communication session.

Abstract
A communication terminal has an EVDO radio control section which performs radio communication control based on an EVDO communication system, and a data communication control section which releases a data link and requests the EVDO radio control section to release a communication session if a power-off command is entered. The EVDO radio control section releases the communication session in response to the communication session release request made by the data communication control section. When the EVDO radio control section releases the communication session based on a command for a power-off processing, the EVDO radio control section maintains the communication session released. When the EVDO radio control section releases the communication session based on any command other than the command of the power-off processing, the EVDO radio control section performs the reconnection processing of the communication session.

9. A communication terminal, comprising:
-
a radio control section which performs radio communications conforming to a first communication system for establishing a communication session by sending a parameter used for communications to a network, and performing a re-establishment processing of the communication session in response to the communication session being released so as to keep the communication session established regardless of whether or not information to be communicated exists, and a second communication system for sharing a communication section with the first communication system and enabling to establish the communication session when a communication connection is established, wherein when the radio control section performs radio communications conforming to the first communication system and the radio control section releases the communication session based on a power-off processing of the communication terminal, the radio control section maintains the communication session released without performing the re-establishment processing of the communication session. - View Dependent Claims (10, 11, 12, 13, 20)

14. A communication terminal conforming to a communication system for establishing a communication session by sending a parameter used for communications to a network, and performing a re-establishment processing of the communication session in response to the communication session being released so as to keep the communication session established regardless of whether or not information to be communicated exists, comprising:
-
a radio control section which performs radio communications based on the communication system; and a data communication control section which releases a data link and requests the radio control section to release the communication session if a power-off command is entered, wherein the radio control section releases the communication session in response to the communication session release request made by the data communication control section, and when the radio control section releases the communication session based on a command for a power-off processing of the communication terminal, the radio control section maintains the communication session released without performing the re-establish processing of the communication session. - View Dependent Claims (15, 16, 17)

18. A communication method of a communication terminal which performs radio communications conforming to a first communication system for establishing a communication session by sending a parameter used for communications to a network, and performing a re-establishment processing of the communication session in response to the communication session being released so as to keep the communication session established regardless of whether or not information to be communicated exists, and a second communication system for sharing a communication section With the first communication system and enabling to establish the communication session when a communication connection is established,
wherein when the communication terminal performs radio communications conforming to the first communication system and the communication session is released based on a power-off processing of the communication terminal, the communication session is maintained released without performing the re-establishment processing of the communication session.
