Claims19
A method, comprising:
- receiving at a network element a communication from user equipment including a private identity of the subscriber, wherein the communication from the user equipment comprises a session initiation protocol register request and wherein the communication is an integrity protected communication;
- assigning, by the network element, a random string to the private identity, wherein the random string is configured to serve as a temporary private identity;
- and
- delivering the random string to the user equipment using integrity protected communication.

A system, comprising:
- a user equipment;
- and
- a network element configured to receives a communication from the user equipment, to assign a random string to the private identity, wherein the random string is configured to serve as a temporary private identity, wherein the communication from the user equipment comprises a session initiation protocol register request, and wherein the communication is an integrity protected communication, and to deliver the random string to the user equipment using integrity protected communication.
An apparatus, comprising:
- reception means for receiving a communication from user equipment including a private identity of a subscriber, wherein the communication from the user equipment comprises a session initiation protocol register request and wherein the communication is an integrity protected communication;
- assigning means for assigning a random string to the private identity, wherein the random string is configured to serve as a temporary private identity;
- and
- delivery means for delivering the random string to the user equipment using integrity protected communication.
