TELECOMMUNICATIONS SYSTEMS AND METHODS

摘要

A method of handling a telephone call request received from a calling party in a wireless telecommunications network is described. The method comprises receiving from a calling party a request to establish a telephone call with an intended recipient party; generating a routing information request message identifying the intended recipient party; receiving the routing information request message identifying the intended recipient party at a service apparatus associated with a call-handling service of the wireless telecommunications network; sending a response to the routing information request message providing routing information associated with the service apparatus instead of the intended recipient party such that subsequent signalling associated with the request to establish a telephone call from a calling party is routed to the service apparatus; identifying an alternative recipient party associated with the intended recipient party; obtaining routing information associated with the intended recipient party from a home location register; and routing a request to establish a telephone call with the calling party to the intended recipient party and / or the alternative recipient party. Thus a scheme is provided that allows two parties to work together to manage incoming calls for one of the parties in wireless telecommunications network.
