摘要:
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 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 the calling number to a mobile positioning center in the mobile access network, which then can retrieve location information for the subscriber. After receiving location information from the mobile positioning center, the media gateway control function selects an emergency center and sends a location indication for the subscriber thereto in a circuit-switched control message for initiating an emergency call, according to prevailing standards.
