Correlating communication sessions
First Claim
1. A subscription entity in a communication system, said subscription entity comprising:
- one or more processors, andone or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the subscription entity to perform the following;
maintaining subscription data of a user, the subscription data comprising at least one Circuit Switched identity of the user and at least one IP Multimedia Subsystem (IMS) identity of the user,assigning one of the identities in the subscription data as a correlation identity for the user for correlating a Circuit Switched call of the user to a session initiation protocol (SIP) session of the user, andsending an indication of the correlation identity to a session handling entity,wherein said subscription entity provides said correlation identity to a session handling entity for use by said session handling entity in order to perform a domain transfer of the user from a circuit switched domain to an IMS domain, andwherein the correlation identity comprises a mobile subscriber international ISDN number (MSISDN) of the user and wherein the correlation identity is bound to a private IMS identity of the user.

Abstract
The present invention relates to a session handling entity in a communication system, the session handling entity (S-CSCF) maintain a relationship between at least one public user identity, at least one private user identity and at least one contact address of a user of a communication system. Then receives from a subscription entity an indication of a correlation identity associated with the user, and stores the indication of the correlation identity as part of the relationship maintained by the maintaining means. When a session request of the user is received, determining the correlation identity for the user based on a contact address of the user included in the session request and the indication of a correlation identity associated with the user take place, and the correlation identity is included in the session request.

3. A method for correlating sessions in a communication system, said method comprising:
-
maintaining subscription data of a user, the subscription data comprising at least one Circuit Switched identity of the user and at least one IP Multimedia Subsystem (IMS) identity of the user, assigning one of the identities in the subscription data as a correlation identity for the user for correlating a Circuit Switched call of the user to a session initiation protocol (SIP) session of the user, and correlating the Circuit Switched call of the user to the session initiation protocol (SIP) session of the user based on the correlation identity, wherein said method is performed by a subscription entity in a communication system to enable said subscription entity to provide said correlation identity to a session handling entity for use by said session handling entity in order to perform a domain transfer of the user from a circuit switched domain to an IMS domain, and wherein the correlation identity comprises a mobile subscriber international ISDN number (MSISDN) of the user and wherein the correlation identity is bound to a private IMS identity of the user. - View Dependent Claims (4, 5)

6. A session handling entity in a communication system, said session handling entity comprising:
-
one or more processors, and one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the session handling entity to perform the following; maintaining a relationship between at least one public user identity, at least one private user identity and at least one contact address of a user of a communication system, wherein the maintained relationship comprises at least one Circuit Switched identity of the user and at least one IP Multimedia Subsystem (IMS) identity of the user, receiving from a subscription entity an indication of a correlation identity associated with the user, storing the indication of the correlation identity as part of the relationship being maintained, receiving a session request of the user, determining the correlation identity for the user based on the at least one contact address of the user included in the session request and the indication of the correlation identity associated with the user, and including the correlation identity in the session request to correlate a Circuit Switched call to a session initiation protocol (SIP) session, wherein said session handling entity obtains said correlation identity from said subscription entity for use by said session handling entity in order to perform a domain transfer of the user from a circuit switched domain to an IMS domain, and wherein the correlation identity comprises a mobile subscriber international ISDN number (MSISDN) of the user and wherein the correlation identity is bound to a private IMS identity of the user. - View Dependent Claims (7, 8, 9, 10)

11. A method of correlating sessions in a communication system, said method comprising:
-
maintaining a relationship between at least one public user identity, at least one private user identity and at least one contact address of a user of a communication system, wherein the maintained relationship comprises at least one Circuit Switched identity of the user and at least one IP Multimedia Subsystem (IMS) identity of the user, receiving from a subscription entity an indication of a correlation identity associated with the user, storing the indication of the correlation identity as part of the maintained relationship, receiving a session request of the user, determining the correlation identity for the user based on the at least one contact address of the user included in the session request and the indication of the correlation identity associated with the user, and including the correlation identity in the session request to correlate a Circuit Switched call to a session initiation protocol (SIP) session, wherein said method is performed by a session handling entity in a communication system to obtain said correlation identity from said subscription entity for use by said session handling entity in order to perform a domain transfer of the user from a circuit switched domain to an IMS domain, and wherein the correlation identity comprises a mobile subscriber international ISDN number (MSISDN) of the user and wherein the correlation identity is bound to a private IMS identity of the user. - View Dependent Claims (12, 13, 14)
