The present invention provides for a sending communication client to create and send a token, which includes control indicia pertaining to contact information and communication rules for using the contact information for an associated user, to a receiving communication client. The communication rules control how receiving communication clients can use the contact information to initiate communications with the sending user, using one of the addresses or telephone numbers. The receiving communication client will keep certain, if not all, of the contact information and perhaps the communication rules inaccessible to a user of the receiving communication client; however, the receiving communication client can use the contact information to initiate communications with one of the communication clients of the sending user. As such, the sending user can keep contact information confidential, yet let certain parties use the information according to communication rules.

Tokens for contact information

A communications architecture for enabling IP-based mobile communications includes a Local Service Function (LSF) component configured to serve as an IP-based serving area network for a set of x-Access Networks, and a Network Service Function (NSF) component configured to serve as an IP-based home network by managing a MN's subscription and associated profile so that the MN is authorized to use the resources of the LSF. An x-Access Network (xAN) is interconnected to the LSF and NSF for providing heterogeneous Layer 2 access for MNs irrespective of access technology.
