The identity information request message comprises a first public identity for a subscriber of the cellular communication system. A public identity processor209determines a first set of public identities which comprises a plurality of public identities associated with the subscriber in response to the public identity. A message generator211generates an identity response message, such as a SIP 200OK message, comprising the first set of public identities.
