| 20080268809 | Method and Apparatus for Handling Emergency Calls in a Packet Switched Radio Access Network - 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. | 10-30-2008 |
| 20100273451 | Method and Apparatus for Mobile Terminal Positioning Operations - In one aspect of the invention presented herein, a mobile terminal requests positioning assistance data from its supporting wireless communication network, in response to receiving a positioning request from a positioning node. Further, in response to receiving the positioning assistance data from the network, the mobile terminal sends the positioning assistance data to the positioning node. In this manner, the positioning node advantageously gains access to network-generated positioning assistance data without need for requesting it from the network. In at least one embodiment, the mobile terminal receives the positioning request from the positioning node over a User Plane (UP) connection. However, the mobile terminal sends the positioning assistance data request to the base station over a Control Plane (CP) connection, and receives the requested positioning assistance data via the CP. The terminal transfers that data to the UP and sends it to the positioning node. | 10-28-2010 |
| 20110098059 | METHOD AND ARRANGEMENT TO MONITOR DISTANCES AMONG A GROUP OF ELECTRONIC COMMUNICATION DEVICES - A method and service-related nodes for providing a deferred distance notification for at least two user devices. A Location-based gateway receives a request for a deferred distance notification for user devices, and sends a request to a Location enabler for the location of the user devices. The gateway receives location data from the Location enabler, and monitors the fulfillment of user device distance-related event criteria. When a user device distance-related event criterion is fulfilled, the gateway triggers the deferred distance notification, and sends the notification of the user device distance event to an application node. The application node sends a location request after which the Application node receives the notification. Distance notification can thus be provided to a user requesting a location-deferred service, such that the location of entire groups of users can be revealed to the requesting party. | 04-28-2011 |
