Management of multiple user identities in a communication system

A convergence server (CS), comprising:

• a registry, which is arranged to hold an association between at least first and second private identities of at least respective first and second communication terminals and a common public identity different from at least the first and second private identities;
• and
• a processor, which is arranged to store in an identity database a registration of the public identity in addition to registrations of at least the first and second private identities stored in the identity database, so as to cause the identity database to simultaneously maintain the registrations of the public identity and of at least the first and second private identities, to receive a request to set up a call in which the public identity serves as one of a source and a destination of the call, and to establish the call between a third communication terminal and one of at least the first and second communication terminals responsively to the association and to the simultaneously-maintained registrations.

A computer software product for communication, the product comprising a computer-readable medium, in which program instructions are stored, which instructions, when read by a computer, cause the computer to hold an association between at least first and second private identities of at least respective first and second communication terminals and a common public identity different from at least the first and second private identities, to store in an identity database a registration of the public identity in addition to registrations of at least the first and second private identities stored in the identity database so as to cause the identity database to simultaneously maintain the registrations of the public identity and of at least the first and second private identities, to receive a request to set up a call in which the public identity serves as one of a source and a destination of the call, and to establish the call between a third communication terminal and one of at least the first and second communication terminals responsively to the association and to the simultaneously-maintained registrations.
