Abstract

An interworking function is provided between first and second messaging domains or technologies, when original address/identities of users in the first domain and the second domain are incompatible. Upon receiving from a sender in the first messaging domain a message addressed to a recipient in the second messaging domain, the interworking function provides, for an original sender address or identity received in the message, a new sender address which is valid in the second messaging domain, and inserts the new address in a header field of the message to be forwarded to the recipient in the second messaging domain. Moreover, the interworking function adds the original sender address into the specific header field of the message either as a part of the new sender address or as an attribute.

First claim

The invention claimed is:

1. A method to interwork between messaging service technologies, comprising:
receiving, at an interworking function, a message containing at least one of an original sender address and an identity, which is valid for sending messages in a messaging service of a non-converged messaging technology, but is not valid for sending messages in a messaging service of a converged messaging technology, the message addressed to a recipient operating in the messaging service of the converged messaging technology;
determining, for the at least one of the received original sender address and identity, at least one of a new sender address and identity, which is valid in the messaging service of the converged messaging technology;
inserting the new at least one of the sender address and identity in a header field of the message; and
including the at least one of the original sender address and identity into the message, to enable a reply to the message via a route other than the interworking function,
after a selection of an option to send the reply via the non-converged messaging technology rather than via the converged messaging technology.

2. A method as claimed in claim 1 ,
wherein said message contains at least one of a recipient address and identity which is not valid in the messaging service of the converged messaging technology, and
wherein the method further comprises
providing for the recipient at least one of a new recipient address and identity which is valid in the second messaging service of the converged messaging technology, and
including the recipient address as an attribute into said same header field of the message which includes the at least one of the original sender address and identity.

3. A method as claimed in claim 1 ,
wherein said at least one of the new sender address and identity is a session initiation protocol uniform resource identifier, SIP URI, a secure session initiation protocol uniform resource identifier, SIPS URI, or a telephone uniform resource identifier, tel URI, and
wherein the method further comprises
inserting the new sender address in a P-Asserted-Identity header field of an SIP message to be forwarded to the recipient in the messaging service of the converged messaging technology, and
including the original at least one of the sender address or identity into said P-Asserted-Identity header field of the SIP message either as a part of said new address or identity, or as an attribute.

4. A method as claimed in claim 3 , comprising:
including the original at least one of the sender address and identity to a From header field of the SIP message in at least one of a similar format as in the P-Asserted-Identity header field, and in the original format of the original sender address or identity.

5. A method as claimed in claim 3 ,
wherein said message contains at least one of the recipient address and identity which is not valid in the messaging service of the converged messaging technology, and
wherein the method further comprises
providing for the recipient at least one of a new recipient address and identity which is valid in the messaging service of the converged messaging technology,
including said at least one of the new recipient address and identity into a To header field of the SIP message, and

including the recipient address as at least one of a part of said at least one of the new recipient address and identity, as an attribute into said P-Asserted-Identity header field of the SIP message, and as an attribute into said To header field of the SIP message.

6. A method as claimed in claim 3 ,
wherein said message contains at least one of a recipient address and identity which is not valid in the messaging service of the converged messaging technology, and
wherein the method further comprises including said at least one of the recipient address and identity into a To header field of the SIP message.

7. A method as claimed in claim 1 , wherein said at least one of the new sender address and identity is an address or identity of the interworking function.

8. A method as claimed in claim 1 , wherein said at least one of the new sender address and identity is at least one of an address and identity of the interworking function containing a host part and a user part, said user part containing said original sender address.

9. A method as claimed in claim 1 , wherein said messaging service of the non-converged messaging technology comprises a communication service which allows to transport real time media or discrete media between two or more users, particularly media of one or more of the following services: Short Message Service (SMS), Multimedia Messaging Service (MMS), email, IMPS (Instant Messaging and Presence Service), Simple IM (SIP for Instant Messaging and Presence Leveraging Extensions/Instant Messaging), Voice over IP calls, PoC (Push-to-talk over Cellular).

10. A method as claimed in claim 1 , wherein said messaging service of the converged messaging technology is a converged IP messaging (CPM) domain based on session initiation protocol (SIP) based technologies.

11. A messaging method for a user device, comprising:
receiving, from an interworking function, a message containing at least one of an original sender address and identity, which is valid for sending messages in a messaging service of a non-converged technology, but is not valid for sending messages in a messaging service of a converged messaging technology, the message further containing at least one of a new sender address and identity which is valid in the messaging service of the converged messaging technology, the message addressed to a recipient operating in the messaging service of the converged messaging technology; and
replying via a route other than the interworking function using the at least one of the original sender address and identity,
after a selection of an option to send the reply via the non-converged messaging technology rather than via the converged messaging technology.

12. A method as claimed in claim 11 ,
wherein said at least one of the new sender address and identity is at least one of a session initiation protocol uniform resource identifier, SIP URI, a secure session initiation protocol uniform resource identifier, SIPS URI, and a telephone uniform resource identifier, tel URI,
wherein the new sender address is in a P-Asserted-Identity header field of an SIP message, and
wherein the original at least one of the sender address and identity is in said P-Asserted-Identity header field of the SIP message as a part of at least one of said new at least one of the sender address and identity, and an attribute.

13. A method as claimed in claim 12 ,
wherein the original at least one of the sender address and identity is in a From header field of the SIP message in at least one of a similar format as in the P-Asserted-Identity header field, and in the original format of the original sender address or identity.

14. A method as claimed in claim 11 , wherein said at least one of the new sender address and identity is at least one of an address and identity of the interworking function.

15. A method as claimed in claim 11 , wherein said at least one of the new sender address and identity is at least one of an address and identity of the interworking function containing a host part and a user part, said user part containing said original sender address.

16. A method as claimed in claim 11 , wherein said messaging service of the non-converged messaging technology comprises a communication service which allows to transport rea
