Abstract

The invention relates to a method of routing a call made by a calling party to a fixed telephone number of a called party, wherein the call is routed to one or more mobile terminals (34) via an Internet Protocol network (12) and a wireless access point (10) associated with the fixed telephone number if the one or more mobile terminals (34) are located in an area covered by the wireless access point (10), or to an alternative terminating point if the one or more mobile terminals (34) are located outside the area. A specific Service Control Point is arranged to store a list that comprises alternative terminating points for the calls to the fixed number.

A method of routing a call made by a calling party to a fixed telephone number of a called party, the fixed telephone number being associated with a subscriber, the method comprising

checking whether a first mobile terminal associated with the subscriber is available to receive the call in an area covered by a wireless access point, and
if so routing the call to the first mobile terminal via an Internet Protocol (IP) network and a wireless access point associated with said fixed telephone number, and
if not, determining whether an indicator associated with said fixed number indicates that the call can be charged to the called party,
if the indicator indicates that the call can be charged to the called party, routing said call to the first mobile terminal via a mobile telephone network, and
if the indicator does not indicate that the call can be charged to the called party, routing the call to a predetermined alternative terminating point, the alternative terminating point being different from the first mobile terminal.

A service node for use in a telecommunication network, said Service node being arranged to receive a request for setting up a connection from a Telephony switch of a fixed telephone network and to send a connection message to said Telephony switch, said Service node being arranged to store for each of a plurality of subscribers:

a fixed telephone number,
information identifying one or more related areas associated with said fixed telephone number, and
a list comprising identities of one or more associated terminating points and a predetermined alternative terminating point, and for each associated terminating point an area presence indicator, said Service node further being arranged to:
receive entry/exit triggers from an area presence service capable of detecting entry in and exit from said one or more related areas by said one or more associated terminating points;
update said area presence indicators based on received entry/exit triggers so that when an entry trigger is received, the area presence indicator is given a value ‘in’ and when an exit trigger is received, the area presence indicator is given a value ‘out’;
determine said connection message by using a first associated terminating point in said list for which the associated area presence indicator has a value ‘in’, or, in case none of the associated terminating points has a presence indicator with value ‘in’, by using a predetermined alternative terminating point;
