Abstract

A call in request is transmitted from a wireless base station to a wireless communication terminal apparatus when there is a call in from a service center. If the wireless communication terminal apparatus does not respond, the wireless base station is reset and, after the reset is completed, a call in request is transmitted to the wireless communication terminal apparatus again. In addition, if out of standby occurs, the wireless communication terminal apparatus notifies the wireless base station to that effect and the wireless base station changes a forward pattern of a notification signal.

Claims

1. A wireless communication system comprising

a base station;

and

a wireless communication apparatus,

wherein the wireless communication system resets transmission timing for retransmitting of an incoming call signal transmitted from the base station and addressed to the wireless communication apparatus in a case where a response signal in response to the incoming call signal from the base station and addressed to the wireless communication apparatus is not received from the wireless communication apparatus.

2. A system according to claim 1, wherein the base station resets the transmission timing in a case where the response signal in response to the incoming call signal from the base station and addressed to the apparatus designated by an incoming call is not received.

3. A base station for controlling wireless communication with a wireless communication apparatus, comprising:

transmitting means for transmitting an incoming call signal addressed to the wireless communication apparatus; and

reset means for resetting transmission timing for retransmitting of the incoming call signal addressed to the wireless communication apparatus in a case where a response signal in response to the incoming call signal addressed to the wireless communication apparatus is not received from the wireless communication apparatus.

4. A base station according to claim 3, wherein the reset means is configured to reset transmission timing when the response signal in response to the incoming call signal addressed to the wireless communication apparatus designated by an incoming call is not received.

5. A computer program embodied in a computer readable medium for a base station comprising the programming steps of:

transmitting an incoming call signal addressed to the wireless communication apparatus; and

resetting transmission timing for retransmitting of the incoming call signal addressed to the wireless communication apparatus in a case where a response signal in response to the incoming call signal addressed to the wireless communication apparatus is not received from the wireless communication apparatus.

6. A method of transmitting an incoming call signal from a base station comprising:

transmitting an incoming call signal addressed to the wireless communication apparatus; and

resetting transmission timing for retransmitting of the incoming call signal addressed to the wireless communication apparatus in a case where a response signal in response to the incoming call signal addressed to the wireless communication apparatus is not received from the wireless communication apparatus.

7. A method according to claim 6, wherein in said resetting transmission timing, the retransmission timing is reset in a case where the response signal in response to the incoming call signal from the base station and addressed to the apparatus designated by an incoming call is not received.
