Abstract

A wireless communication network is disclosed having a circuit switched network architecture and a packet switched network architecture, at least part of the packet switched network architecture supporting IP multimedia functionality, wherein the support of IP multimedia functionality is identified in a pre-registration communication between a user and the network.

Claims

1. A method of indicating the functionality of a packet switched wireless network comprising transmitting, in a pre-registration communication, an indication of the functionality of the packet switched network.

2. A method according to claim 1 wherein the functionality is Internet protocol functionality.

3. A method according to claim 2 wherein the Internet protocol functionality is Internet protocol multimedia functionality.

4. A method according to claim 1 wherein the functionality is identified in a broadcast control signal.

5. A method according to claim 1 wherein the functionality is identified in a transmission identifying the packet switched network.

6. A method according to claim 5 wherein the transmission includes a routing area code.

7. A method according to claim 1 wherein the transmission includes packet data protocol context.

8. A method according to claim 1 utilised in a GPRS network.

9. A method according to claim 8 wherein the transmission includes a GPRS context.

10. A wireless communication network having a circuit switched network architecture and a packet switched network architecture, at least part of the packet switched network architecture supporting IP multimedia functionality, wherein the support of IP multimedia functionality is identified in a pre-registration communication between a user and the network.

11. A wireless communication network according to claim 10 wherein the pre-registration communication comprises a transmission from the packet switched network architecture to a user.

12. A wireless communication network according to claim 10 wherein the pre-registration communication comprises a broadcast.
