Method of Routing a Call Made to a Fixed Telephone Number of a UMA-Subscriber in a Telecommunication Network

摘要

The invention relates to a method of routing a call made to a fixed telephone number of a UMA-subscriber in a telecommunication network. A service control entity stores a so-called ‘near list’ comprising a cell identifier of each cell overlapping a WLAN coverage area of a WLAN AP associated with the UMA-subscriber. The service control entity also receives location information of the UMA-subscriber from a switching node (2) or from a location server (16). If the cell identifier of the serving cell is in the near list, the service control entity prompt the caller to select out of a list of options. If the cell identifier of the serving cell is not in the near list, the caller will be prompted but with a different message and with different options to select. The caller is for example offered the opportunity to wait for the called party to arrive at home, and be dialed back.
