CALL ROUTING TO WIRELESS ROAMERS IN MOBILE TELECOMMUNICATION SYSTEMS

摘要

A method of serving a roaming subscriber in a telecommunication system having at least one wireless service carrier (4) that can communicate with the roaming subscriber (17). A wired exchange carrier (14) can communicate with the wireless service carrier and has access to a long distance trunk. A call destined for the roaming subscriber is received at the wired exchange carrier via the long distance trunk, and includes both a routing number corresponding to the roaming address of the roaming subscriber and a call routing parameter corresponding to the wireless service carrier. The call is selectively sent to the wireless service carrier in response to the call routing parameter, and a communication channel between the wireless service carrier and the roaming subscriber is then established in response to the routing number.
