A method and apparatus for providing location information for subscribers connected to a packet-switched mobile access network in connection with emergency calls made over a multimedia service network. An emergency request is received at the multimedia service network from a subscriber (A) containing the calling number of the subscriber. In response thereto, a media gateway control function in the multimedia service network sends a location query including said calling number to a mobile positioning centre in the mobile access network, which then can retrieve location information for the subscriber. After receiving location information from the mobile positioning centre, the media gateway control function selects an emergency centre and sends a location indication for the subscriber thereto in a circuit-switched control message for initiating an emergency call, according to prevailing standards.
A method, executed in a multimedia service network, of providing location information to an emergency centre in a circuit-switched network, for a subscriber connected to a packet-switched mobile access network, comprising the following steps:
