  • Patent number: 8934913
    Abstract: Cell relocation procedures to address handover between a macro radio network controller (RNC) and a home base station in a wireless communication network, while accounting for access control or membership verification procedures needed to support a Closed Subscriber Group (CSG) at the home base station. An example method begins with the receiving of a request for handover of the mobile terminal from an RNC of the macro wireless network. A closed subscriber group (CSG) identifier for the home base station and a cell access mode for the home base station are then sent, to a core network node associated with the macro wireless network, for use by the core network node in membership verification or access control for the mobile terminal. In response, the home base station receives a CSG membership status for the mobile terminal from the core network node.

  • Patent number: 8886183
    Abstract: A method and apparatus for allowing a terminal to attach to an access network. The terminal determines that the access network does not support a subscriber identifier used by the terminal, and so it attaches to the access network using an IMSI, the IMSI having been pre-provisioned at the terminal. The terminal, once attached, sends a request for a roaming IMSI to a remote node in the subscriber's home network. It then receives a roaming IMSI from the remote, the roaming IMSI being associated with the subscription and related subscriber identifier. The terminal detaches from the access network and then re-attaches to the access network using the roaming IMSI.

  • Publication number: 20140329523
    Abstract: A call loop avoidance capability is provided for preventing formation of a call loop resulting from handling of a mobile terminated (MT) call in parallel with a location update for a mobile device (MD) in a wireless communication network. The call loop avoidance capability prevents formation of a call loop between an old mobility and call management entity (MCME) and a new MCME when delivery of an MT call to an MD is performed while the MD is in the process of moving from the old MCME to the new MCME using a location update procedure. An enhanced call routing procedure supports direct delivery of the MT call from the new MCME to the MD (rather than delivery of the MT call by the new MCME to the MD via the old MCME) in order to prevent formation of a call loop between the old MCME and the new MCME.

  • Patent number: 8880026
    Abstract: The present invention provides a method and apparatus of providing network services to a mobile user equipment, where the mobile user equipment is connected to a fixed access network via a Femtocell base station and thus connected to the mobile core network. The mobile core network provides an access token to a Femtocell base station. The Femtocell requests the fixed access network with the access token to perform network resource configuration for the mobile user equipment. The mobile user equipment establishes a network service connection based on the network resource configuration. In this way, technically, it may be guaranteed that the mobile user equipment can be legal listened. Dependent on different service attributes of the mobile user equipment, different network access manners may be implemented, such that operators of mobile and fixed access networks may reasonably commercially apportion the charges based on their respective network resource occupation situations.

  • Patent number: RE45301
    Abstract: The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.
