Patent ID: 8060088

Claim:
A method comprising: allocating an address to a terminal, the terminal being configured to access a communication network via a gateway using a selected access technology out of at least two access technologies common to the terminal and the communication network; sending a registration request from the terminal, the registration request comprising an address of a default agent entity of the terminal as a destination address of the registration request; monitoring messages, by a redirector, to detect a message that comprises the address of the default agent entity and, in response to detecting the registration request received from the terminal that comprises the address of the default agent entity, redirecting, by the redirector, the registration request from the terminal to an intercepting agent entity; intercepting, by the intercepting agent entity, the redirected registration request from the terminal; responding, by the intercepting agent entity, with a registration request response to the terminal, where the registration request response comprises the address of the default agent entity of the terminal as a source address of the registration response and an address of a predetermined agent entity of a plurality of agent entities of the communication network; and registering, based on the response from the intercepting agent entity, the terminal at the predetermined agent entity of the plurality of agent entities of the communication network, wherein the terminal is configured to access based on one of an access via a packet data protocol context and an Internet protocol security (IPsec) access.
