Activating a mobile terminal from mobile network side
First Claim
1. A method of supporting instant messaging for a mobile terminal, comprising:
- receiving, by a mobile application gateway for a packet domain core network which services a plurality of mobile terminals, a request for activating a first mobile terminal of the plurality of mobile terminals to receive a first communication from an instant message server, wherein the first mobile terminal has no IP connection and no static IP address associated with the first mobile terminal, wherein the request is received from the instant message server via an external packet switched network and includes an unique identification number of the first mobile terminal, and wherein the first mobile terminal is running an instant message client requiring continuous availability to receive communications from said instant message server via said external packet switched network;
querying, by the mobile application gateway, a Home Location Register (HLR) for address of a Servicing GPRS Supporting Node (SGSN) where the first mobile terminal is located by utilizing the unique identification number of the first mobile terminal;
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 first mobile terminal to the SGSN;
issuing, by the SGSN, a request to the first mobile terminal, requiring the first mobile terminal to issue a request for activating a Packet Data Protocol (PDP) context to the SGSN;
activating the PDP context for the first mobile terminal in response to receiving, by the SGSN, the request for activating the PDP context issued by the first mobile terminal; and
forwarding said first communication from the instant message server to the first mobile terminal using the activated PDP context.

Abstract
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.

6. A mobile application gateway system for a packet domain core network, comprising:
-
at least one processor; a memory communicatively coupled to the at least one processor and storing instructions executable on the at least one processor; a request receiving module configured to receive a request for activating a first mobile terminal of a plurality of mobile terminals serviced by the mobile application gateway to receive a first communication from an instant message server, the mobile terminal having no IP connection and no static IP address associated with the mobile terminal, wherein the request is received from the instant message server via an external packet switched network and includes a unique identification number of the first mobile terminal, and wherein the first mobile terminal is running an application program client requiring continuous availability to receive communications from the instant message server via the external packed switched network; a query sending module configured to query a Home Location Register (HLR) for address of a Servicing GPRS Supporting Node (SGSN) where the first mobile terminal is located by utilizing the unique identification number of the first mobile terminal; a query receiving module configured to receive address of the Servicing GPRS Supporting Node (SGSN) queried by the HLR; and an activation request sending module configured to send the request for activating the first mobile terminal to the SGSN, wherein responsive to the activation request the SGSN issues a request to the first mobile terminal requiring the first mobile terminal to issue a request for activating a Packet Data Protocol (PDP) context to the SGSN, and the SGSN activates the PDP context for the first mobile terminal responsive to receiving the request for activating a PDP context from the first mobile terminal; wherein the mobile application gateway forwards said first communication from the instant message server to the first mobile terminal using the activated PDP context. - View Dependent Claims (7, 8)
