Abstract

A method, and related equipment, for interoperating between a device (11a) in a first network, such as an IMS network, and a device (12a) in a second network (12), such as a WV network, the first network using a first protocol (SIP) requiring that a message have a request uniform resource identifier including an address scheme, and the second network (12) using one or more other protocols. The method includes a step (41) of converting a message constructed according to the first protocol (SIP) but having as an address scheme indicating a protocol of the second network (such as “wv:”) to a message in which the address scheme is changed (e.g. to “sip:”) to indicate the protocol of the first network and in which a user uniform resource locator parameter is provided having a value indicating the original scheme, before conversion (i.e. “wv” in the example given).

Claims

1. A method for interoperating between a device operable in a first network and a device operable in a second network, the first network having a first server for communicating with the first device using a first protocol requiring that a message have a request uniform resource identifier including an address scheme, the second network having a second server for communicating with other servers in said second network using a second protocol and with the second device using a third protocol, the method comprising:

converting a message constructed according to said first protocol but having as the address scheme a value indicating a protocol of the second network, into a converted message in which the address scheme has instead a value indicating the protocol of the first network, and the converted message also having a user uniform resource locator parameter with a value indicating a protocol of the second network; and

transmitting the converted message on a communication path leading to a gateway element.

2. A method as in claim 1, wherein said first device performs said converting of said message.

3. A method as in claim 1, wherein said first server performs said converting of said message.

4. A method as in claim 1, further comprising translating to said second protocol or to said third protocol said converted message received according to said first protocol from said first server, or translating to said third protocol said message received from said first device without using said first server, and communicating said translated message to said second network.

5. A method as in claim 4, wherein said first network is an Internet Protocol Multimedia Subsystem network, and said translating is performed by an Application Server connected to said first network.

6. A method as in claim 4, wherein said first network is an Internet Protocol Multimedia Subsystem network, and said translating is performed by a gateway accessible to an Application Server connected to said first network.

7. A method as in claim 4, wherein said first network is an Internet Protocol Multimedia Subsystem network including call state control function entities, and said translating is performed by a gateway accessible to the Internet Protocol Multimedia Subsystem network entities connected to said first network.

8. A device, operable according to the method of operation of the first device as recited in claim 2.

9. A server, operable according to the method of operation of the first server as recited in claim 3.

10. An apparatus, comprising means for performing said translating said converted message to said second protocol or to said third protocol as recited in claim 4.

11. A system, comprising:

a first device, a first server, and an apparatus as in claim 10, the first device operable in a first network and able to interoperate with a device operable in a second network, the first network including the first server for communicating with the first device using a first protocol requiring that a message have a request uniform resource identifier including an address scheme, the second network having a second server for communicating with other servers in said second network using a second protocol and with the second device using a third protocol, either the first device or the first server comprising;

means for converting a message constructed according to said first protocol but having as the address scheme a value indicating a protocol of the second network to a converted message in which the address scheme has instead a value indicating the protocol of the first network, and the converted message also having a user uniform resource locator parameter with a value indicating a protocol of the second network; and

means for transmitting the converted message on a communication path leading to a gateway element.

12. An apparatus, comprising:

converting functionality, for converting a received message constructed according to a protocol of a first network but having as an address scheme a value indicating a protocol of a second network, into a converted message in which the address scheme has instead a value indicating the protocol of the first network, with the converted message also having a user uniform resource locator parameter with a value indicating a protocol of the second network; and

transmitting functionality, for providing the converted message for transmission on a communication path leading to a gateway element.

13. An apparatus as in claim 12, wherein the first and second protocols are different and are either a session initiation protocol or a wireless village protocol.

14. An apparatus as in claim 12, wherein the user uniform resource locator parameter has a value “

wv”

or has a value “

sip”

.

15. A server of a communication network, comprising functionality for routing messages to and from a gateway server, and further comprising an apparatus as in claim 12.

16. A server of a communication network as in claim 15, wherein the server is configured for communication using session initiation protocol.

17. A server of a communication network as in claim 15, wherein the server is configured for communication using wireless village protocol.

18. A user equipment terminal configured for communication with a server of a communication network, comprising an apparatus as in claim 12.

19. An apparatus, comprising:

means for converting a message constructed according to a protocol of a first network but having as an address scheme a value indicating a protocol of a second network, into a converted message in which the address scheme has instead a value indicating the protocol of the first network, with the converted message also having a user uniform resource locator parameter with a value indicating a protocol of the second network; and

means for providing the converted message for transmission on a communication path leading to a gateway element.

20. An apparatus as in claim 19, wherein the first and second protocols are different and are either a session initiation protocol or a wireless village protocol.

21. A method, comprising:

converting a message constructed according to a protocol of a first network but having as an address scheme a value indicating a protocol of a second network, into a converted message in which the address scheme has instead a value indicating the protocol of the first network, with the converted message also having a user uniform resource locator parameter with a value indicating a protocol of the second network; and

providing the converted message f or transmission on a communication path leading to a gateway element.

22. A method as in claim 21, wherein the first and second protocols are different and are either a session initiation protocol or a wireless village protocol.
