<p>The relay service control procedure enables network operators and/or service providers to provide home services to the visiting user, who is located in a visited serving network, when the visited serving network is not equipped to offer the home services. This is accomplished by enabling the visited serving network to expand their portfolio of available wireless services on an as needed basis. It obtains the needed Service Logic Program (SLP) from the Service Control Function of the user's home network or the Service Control Function of any other supporting network in the wireless communication system that supports the requested service. The visited serving network executes the relayed Service Logic Program in its Service Control Function and directly controls the provision of the requested service to the visiting user. The use of a supporting network for wireless telecommunication systems assists in the execution of the relay service control procedure to provide desired services to the mobile terminal users, directly through the inter-connection of the visited serving network with the supporting network. The network inter-connection is achieved by the use of a unique Network-to-Network Interface protocol that enables a supporting network operator to become a purveyor of third generation mobile telecommunications services to subscribers who are presently served by wireless communications networks that are incapable of providing these services. <IMAGE></p> |
