<p>A mobile communication terminal and a management method for an always preserved PDP context using for the mobile communication terminal, in which not delivering data to the mobile communication terminal from a push contents server can be avoided and also reestablishing an undesirable always preserved PDP context can be avoided, are provided. The timer in the mobile communication terminal is started at the time when the mobile communication terminal moved from a service area to an out of service area. The full measuring time value in the mobile communication terminal is set to be smaller than that of a PRAUT (periodic routing area update timer) in an RNC (resource network controller). In case that the mobile communication terminal returned to the service area, when the timer in the mobile communication terminal was full but within the full measuring time value of the PRAUT, the always preserved PDP context is reestablished, and it is not necessary to establish an undesirable new PDP context needing a new IP address. Therefore, the IP address of the mobile communication terminal, which was decided at the time when the always preserved PDP context was established and has been held in the push contents server, is not renewed meaninglessly. With this, error delivery of the push data caused by not matching the IP address can be avoided.</p> |
