Abstract

A mobile/portable terminal being connected at any time to a PDP (Packet Data Protocol) context in order to receive a push service from a server is provided with PDP Context Management which performs a health check between the mobile/portable terminal and a terminal point of the PDP context on the side of a network.

Claims

1. A mobile/portable terminal to which a PDP (Packet Data Protocol) context is connected at any time in order to receive a push service from a server, comprising

PDP Context Management which performs health check between the terminal, and a terminal point of the PDP context on the side of a network.

2. The mobile/portable terminal according to claim 1, wherein

the PDP Context Management has a function at least to establish the PDP context at power-on of the terminal and to re-establish the PDP context in a case in which it is detected that the terminal is out of a service area for a long time, or for a short time, and in a case in which a request for deactivation of the PDP context is received from the side of the network.

3. The mobile/portable terminal according to claim 1 or 2, wherein

the PDP context is a logical session in an Air network which terminates at MTF (Mobile Termination Function).

4. A always-on PDP Context Management method of a portable/portable terminal to which a PDP (Packet Data Protocol) context is connected at any time in order to receive a push service from a server, wherein

health check is performed between the terminal, and a terminal point of the PDP context on the side of a network.

5. The always-on PDP Context Management method according to claim 4, wherein

At least, processing for establishment of the PDP context at power-on of the mobile/portable terminal and for re-establishment of the PDP context in a case in which it is detected that the terminal is out of a service area for a long time, or for a short time, and in a case in which a request for deactivation of the PDP context is received from the side of the network.

6. The always-on PDP Context Management method according to claim 4 or 5, wherein

the PDP context is a logical session in an Air network which terminates at MTF (Mobile Termination Function).
