METHOD, SYSTEM AND APPARATUS FOR CREATING A REVERSE TUNNEL

摘要

A method, system and apparatus for creating a reverse tunnel in a communication system is provided. The method includes obtaining an authentication key from an entity in the communication system. The method further includes manipulating a registration request message (402) sent by a mobile station (106) to a local agent (110) at an external agent (112) and re-calculating a digital signature of the registration request message using the authentication key. This manipulation is performed by using the authentication key. Thereafter, the registration request message is sent (516) from the external agent to the local agent for creating the reverse tunnel.
