Gateway GPRS support node and method therefor
First Claim
1. A method within a gateway GPRS support node (GGSN) for processing a received SMS message for a specified mobile terminal, comprising:
- receiving the SMS message transmitted by an SMS service center in an IP protocol at a dedicated IP address port for receiving SMS messages in an IP data packet format;
determining whether the specified mobile station has an active PDP context established;
determining a serving GPRS support node (SGSN);
removing IP headers and for combining IP packets to form a legacy format SMS message; and
delivering the legacy format SMS message to an SMS proxy module within the gateway GPRS support node for processing through a GPRS tunnel.

Abstract
A system for delivering SMS messages to a mobile terminal includes an apparatus and method that deliver the SMS messages either using legacy SMS message formats or data packet formats. Additionally, a connection is created between a message center and a gateway GPRS support node wherein SMS messages may be transmitted to the gateway GPRS support node in a data packet format. To provide this capability, the gateway GPRS support node includes a unique port address for receiving SMS messages and circuitry for processing SMS messages received in a data packet format. A serving GPRS support node is formed to include circuitry for determining whether to transmit the SMS message to the mobile terminal in a data packet format or in a legacy SMS message format.

8. A gateway GPRS support node (GGSN), comprising:
-
circuitry coupled to receive data packets from a private data network for delivery to a specified mobile terminal; circuitry coupled to receive data packets from the Internet for delivery to the specified mobile terminal; circuitry for determining whether the specified mobile station has an active PDP context established; circuitry for determining a serving GPRS support node (SGSN); and circuitry coupled to receive and process SMS messages from the Internet at a specified port that is for receiving only SMS messages in an IP protocol data packet format, which SMS messages are for delivery to the specified mobile terminal. - View Dependent Claims (9)

10. A method in a gateway device for receiving and processing data packets that are to be transmitted through a plurality of systems for delivery to a mobile terminal, comprising:
-
receiving the data packets at a dedicated data packet port reserved for receiving SMS messages in an IP data packet format from an SMS message center over a data packet network; determining that the data packets collectively form an SMS message; generating a query to GPRS HLR to obtain location information for the mobile terminal; initiating logic that causes the GGSN to determine if an active PDP context exists for the mobile terminal; and transmitting the data packets to the mobile terminal by way of the plurality of systems. - View Dependent Claims (11, 12, 13)
