ACTIVATING A MOBILE TERMINAL FROM MOBILE NETWORK SIDE

摘要

Disclosed is a method of activating a mobile terminal from mobile network side and a mobile application gateway system. The method comprises: receiving, by a mobile application gateway, a request for activating the mobile terminal, the request including an unique identification number of the mobile terminal; querying, by the mobile application gateway, a HLR for address of a SGSN where the mobile terminal is located; returning, by the HLR, the queried address of SGSN to the mobile application gateway; sending, by the mobile application gateway, the request for activating the mobile terminal to the SGSN; issuing, by the SGSN, a request to the mobile terminal, requiring the mobile terminal to issue a mobile terminal initiated PDP context activation request. The method enables an instant messaging user at a mobile terminal to automatically open an IP connection if there is any message to be received after the IP connection is closed.

1. A method of operating an instant message server, comprising:
storing a unique identification number of a first mobile terminal in response to login of an instant message client running on the first mobile terminal; modifying status of the instant message client maintained in the instant message server to a saving mode, wherein the first mobile terminal has no IP connection while in the saving mode and no static IP address is associated with the first mobile terminal; receiving an instant message destined for said first mobile terminal while the status of the instant message client running on the first mobile terminal is the saving mode; responsive to receiving the instant message destined for said first mobile terminal while the status of the instant message client running on the first mobile terminal is the saving mode, sending a request for activating the first mobile terminal to a mobile application gateway for a packet domain core network which services a plurality of mobile terminals including said first mobile terminal, the request being sent via a packet switched network external to said packet domain core network, the request including the unique identification number of the mobile terminal, wherein, responsive to receiving the request for activating the first mobile terminal, the application gateway causes the first mobile terminal to request activation of a Packet Data Protocol (PDP) context by a Servicing GRPS Supporting Node (SGSN) and the SGSN to activate the PDP context and the first mobile terminal to re-establish an IP connection; receiving a login from the instant message client in the first mobile terminal using re-established IP connection; and sending the instant message to the first mobile terminal using the re-established IP connection.
