Abstract

In accordance with one aspect of the present invention, there is provided a method for providing a short messaging service for a device to enable communication of a short message over an Internet Protocol (IP) network, the device adapted to access a telecommunications system communicatively coupled to the IP network, the IP network comprising one or more network nodes, the method comprising: subscribing to an attachment notification, the attachment notification indicating that the device has attached to the telecommunications system and is contactable for communication, said subscribing being performed by a network element communicatively coupled between the device and the one or more network nodes; receiving, at the network element, the attachment notification when the device has attached to the telecommunications system, the attachment notification comprising identification information for the device; and registering the device with at least one of the one or more network nodes for communication of short messages over the IP network, said registering being performed by the network element based on at least some of the identification information received in the attachment notification.

First claim

The invention claimed is:

1. A method for providing a short messaging service via an internet protocol (IP) network for a device by a proxy server for short message service (SMS) in a wireless communication system, the method comprising:
transmitting, by the proxy server, first information requesting an attachment notification to a home subscriber server (HSS), the attachment notification indicating that the device has attached to the wireless communication system;
receiving, by the proxy server, second information including the attachment notification from the HSS when the device has attached to the wireless communication system, the attachment notification comprising identification information for the device; and
transmitting, by the proxy server, third information including a home network domain name corresponding to the device for registering the device in an internet protocol short message gateway (IP-SM-GW) for using an SMS through an SMS service center (SMS-SC) to a call session control function (CSCF) based on the identification information if the attachment notification is received,
wherein the proxy server is an entity separated from the SMS-SC and the IP-SM-GW.

2. The method of claim 1 ,
wherein the identification information comprises contact information for the device, and
wherein the method further comprises:
receiving short message data for delivery to the device; and
transmitting a short message for delivery to the device based on the contact information received in the attachment notification and the short message data.

3. The method of claim 2 , wherein the identification information comprises both a unique identifier for the device and the contact information.

4. The method of claim 3 , wherein the unique identifier comprises one of an international mobile subscriber identifier (IMSI) or an international service provider subscription identifier (IS SI).

5. The method of claim 2 , wherein the contact information comprises an IP address.

6. The method of claim 2 ,
wherein the short message data is configured according to a first network protocol and the short message is configured according to a second network protocol, and
wherein the method further comprises generating the short message from the short message data, said generating being performed by the proxy server for SMS.

7. A proxy server for short message service (SMS) for providing a short messaging service via an internet protocol (IP) network for a device in a wireless communication system, the proxy server for SMS comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
transmit, to a home subscriber server (HSS), first information requesting an attachment notification, the attachment notification indicating that the device has attached to the wireless communication system,
receive, from the HSS, second information including the attachment notification when the device has attached to the wireless communication system, the attachment notification comprising identification information for the device, and
transmit, to a call session control function (CSCF), third information including a home network domain name corresponding to the device for registering the device in an internet protocol short message gateway (IP-SM-GW) for using an SMS through an SMS service center (SMS-SC) based on the identification information if the attachment notification is received,

wherein the proxy server is an entity separated from the SMS-SC and the IP-SM-GW.

8. The proxy server for SMS of claim 7 ,
wherein the identification information comprises contact information for the device, and
wherein the controller is further configured to:
receive short message data for delivery to the device; and
transmit a short message for delivery to the device based on the contact information received in the attachment notification and the short message data.

9. The proxy server for SMS of claim 8 , wherein the identification information comprises both a unique identifier for the device and the contact information.

10. The proxy server for SMS of claim 9 , wherein the unique identifier comprises one of an international mobile subscriber identifier (IMSI) or an international service provider-subscription identifier (IS SI).

11. The proxy server for SMS of claim 8 , wherein the contact information comprises an IP address.

12. The proxy server for SMS of claim 8 , wherein the short message data is configured according to a first network protocol and the short message is configured according to a second network protocol, the proxy server for SMS being further arranged to:
generate the short message from the short message data.

13. The proxy server for SMS of claim 8 , wherein the controller is further configured to:
receive a first message from the device; and
send a second message to at least one of the one or more network nodes based on receipt of the first message.

14. The proxy server for SMS of claim 13 , wherein the second message is a session initiation protocol message.

15. The proxy server for SMS of claim 7 , wherein the first information is transmitted to a home subscriber server for receiving the attachment notification from the home subscriber server.

16. The proxy server for SMS of claim 15 , wherein the attachment notification is transmitted from the home subscriber server to the proxy server for SMS based on data received by the home subscriber server from a packet data network (PDN) gateway following attachment of the device to the wireless communication system.

17. The proxy server for SMS of claim 7 , wherein the controller is further configured to subscribe to user equipment reachability request parameter (URRP) for internet protocol (IP) Sh interface data using diameter protocol.

18. The proxy server for SMS of claim 7 ,
wherein the wireless communication system comprises one or more network nodes,
wherein the one or more network nodes comprise one or more of:
one or more session initiation protocol servers; or
the IP-SM-GW arranged to send short messages to the device and/or receive short messages from the device, and

wherein the proxy server for SMS is arranged to register with at least the IP-SM-GW.

19. The proxy server for SMS of claim 7 , wherein the controller is further configured to:
re-register the device with at least one of the one or more network nodes for communication of the SMS over the IP network based on a specified period.

20. The proxy server for SMS of claim 7 , wherein the wireless communication system comprises a radio access network and the device wirelessly accesses the wireless communication system via the radio access network.
