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 |
20090274069 | INTER-ACCESS NETWORK TOPOLOGY DISCOVERY - The disclosure relates to building a topology map that can be used to provide a requesting wireless terminal with information relevant to its current location. Information on neighboring cells of different access networks is maintained in the topology map. An inter-access network (IAN) topology apparatus builds to topology map based on results of previous IAN session transfers such as handovers from one access network to a different access network. When the requesting wireless terminal currently accessing a current network makes a request for topology information, the IAN topology apparatus provides a list of cells of other than the current access network in the area of the requesting wireless terminal. The requesting wireless terminal uses the information to scan for cells of other access networks to potentially perform the IAN session transfer. The requesting wireless terminal conserves power by scanning only for accessible cells indicated to be in its area. | 11-05-2009 |

20140051443 | Methods and Apparatus for Enhancing Circuit-Switched Call Fallback (CSFB) Service for a Shared Network Node - Methods and apparatus enhance a circuit-switched call fallback (CSFB) service for a user equipment (UE) currently connected to a source cell in a serving radio access technology (RAT) communications network. Multiple different mobile network operators share a target CSFB cell selected for CSFB from one or more circuit-switched capable cells that supports circuit-switched services. Each mobile network operator is associated with a corresponding mobile network identifier. The UE transmits a first message requesting a CSFB service to a source cell radio network node serving the source cell. The source node, in response to the first message, sends a second message to the UE including preferred mobile network identifier information and a target CSFB cell identifier. The UE transmits a third message to a target cell node serving the target CSFB cell to trigger the establishment of a circuit-switched call connection for the UE in the target CSFB cell. The target cell radio network node receives the third message, which includes preferred mobile network information to permit the target node to direct the third message to a core network node operated by one of the mobile network operators identifiable based on the preferred mobile network information. That core network node then initiates the requested CSFB service for the UE. Based on the preferred mobile network identifier information, the UE determines whether a location area update procedure must be performed in the target CSFB cell, and if so, transmits a fourth message to trigger the location area update procedure prior to triggering the establishment of a circuit-switched call connection. | 02-20-2014 |
