  • Location functionality in an interworking WLAN system
    Patent number: 8503427
    Abstract: The present invention relates to system nodes/entities and methods for enabling determination of the location of an attached User Equipment in a tunneled IP network. The User Equipment location can be determined by means of procedures maintained in a Location Function (LF). An application function can retrieve the User Equipment location by querying the Location Function by using the second source address as a key.

  • Method and Network for Managing an Interface for Session-Based Synchronization
    Publication number: 20080247379
    Abstract: A method and network node for supporting a synchronization of a connectivity session location function (CLF) in a communication network. The method uses a processor for sending and receiving messages from a communication network, detecting the unavailability of the CLF, detecting that access information related to the session of the UE is missing from the CLF, receiving missing access information for a session of a UE and synchronizing the CLF on a per session basis. Furthermore, the processor accesses a memory for storing access information and synchronizes the stored access information of the session with the received missing access information of the session of the UE stored during unavailability of the CLF.

  • Policy based media path selection in a broadband access network
    Publication number: 20040213201
    Abstract: Dynamic selection of a media path for a call to or from a multimedia terminal or a voice terminal of a subscriber is provided using policy data defined by the subscriber. A broadband connection is provided between a broadband access node and the multimedia terminal and voice terminal. The broadband access node is connected to both a broadband transport network (BTN) and a narrowband transport network (NTN) to dynamically route calls to and from the BTN and NTN regardless of the subscriber terminal used (e.g., multimedia or voice), based on the subscriber policy data.
