20080305768 | Validating User Identity by Cooperation Between Core Network and Access Controller - An identifier, required by a radio access network controller in order to support resource allocation associated with a predetermined condition, is sent from a core network to the radio access network controller independently of the predetermined condition. The identifier is thus available to the radio access network controller for verification of mobile user identity, regardless of whether it is needed to support resource allocation. A radio access network controller can receive an identifier in a communication sent by a core network according to a communication protocol. The radio access network controller terminates the communication protocol to access the communication, and uses the identifier for verification of mobile user identity. | 12-11-2008 |

20090092097 | METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM - The described technology generally relates to method(s) and arrangement(s) for access control during relocation of a user equipment (UE) into a femto base station (FBS) and dynamic triggering of the relocation into the FBS. A white list is maintained in the UE. The white list includes information on a list of FBSs that the UE is allowed to relocate. The UE detects a target FBS and reports target FBS to a source macro base station (MBS). The source MBS makes a relocation request to a mobility controller. The mobility controller grants or denies the requests or allows the target FBS to make the decision. Upon grant, the UE is relocated to the target FBS. Otherwise, the white list is updated in the UE. | 04-09-2009 |
20090116377 | Early service loss or failure indication in an unlicensed mobile access network - An Unlicensed Mobile Access Network Controller (UNC) and method for providing an early indication of service failure to a mobile station registered with the UNC. When the UNC detects a network failure that prevents service to the mobile station, the UNC prohibits new registrations by other mobile stations, starts a timer, and monitors the network failure to determine if the failure clears. If the failure clears before the timer expires, new registrations are accepted from other mobile stations. However, if the timer expires before the failure clears, the UNC continues to prohibit new registrations from other mobile stations, and deregisters the mobile station when a network Keep Alive timer expires for the mobile station. When a plurality of mobile stations are registered with the UNC, the UNC deregisters the plurality of mobile stations one at a time as the network Keep Alive timer expires for each mobile station. | 05-07-2009 |
20090233601 | METHOD AND SYSTEM FOR IMPROVED HANDOVER OF MOBILE STATIONS OUT OF UNLICENSED MOBILE ACCESS NETWORKS - The present invention provides a system and various methods for handover of a mobile station (MS) ( | 09-17-2009 |
20090275332 | METHOD AND SYSTEM FOR IMPROVED HANDOVER OF MOBILE STATIONS TO UNLICENSED MOBILE ACCESS NETWORKS - A method and system for handover of a mobile station (MS) to an unlicensed mobile access network controller (UNC) in an unlicensed mobile access network (UMAN). In one embodiment, the MS sends an unlicensed mobile access (UMA) radio resource (URR) Registration Request message to the UNC with one or more location identifiers for the MS. The location identifiers may include a GSM Cell Global Identity, an access point (AP) Radio Identity, a set of GPS coordinates, or an AP location. The UNC selects absolute radio frequency channel numbers (ARFCN) and base station identity codes (BSIC) values from a table based on the location identifiers and returns them to the MS in a URR Registration Accept message. | 11-05-2009 |
20100054187 | METHOD AND APPARATUS FOR PROVIDING CIRCUIT SWITCHED DOMAIN SERVICES OVER A PACKET SWITCHED NETWORK - A method of determining a domain mode for a mobile station operating in either a circuit-switched domain or a packet-switched domain. A first domain mode is determined, and then a determination is made whether to rove from the first domain mode to a second domain mode. The determination may be made by a Packet Mobile Switching Center (PMSC) when, for example, the mobile station moves between Routing Areas. Alternatively, the mobile station may make the determination based, for example, on pre-provisioned selection criteria. The mobile station derives a Fully Qualified Domain Name (FQDN) based on a cell identifier of a current cell and uses the FQDN in a DNS query to obtain the IP address of the PMSC. | 03-04-2010 |
20100075651 | Method and Apparatus for Providing Circuit Switched Domain Services Over a Packet Switched Network - A method of establishing a call to or from a mobile station (MS) operating in a Long Term Evolution (LTE) access network. An interface is established between the MS and a Packet Mobile Switching Center (PMSC), and the call is initiated after the network accepts a service request from the MS for an originating call, or after the MS is notified of a terminating call. The PMSC requests packet-switched domain resources from a Policy and Charging Rules Function (PCRF) and establishes a voice bearer channel with an endpoint in the network when the requested resources are available. The PMSC facilitates bidirectional voice traffic between the MS and the endpoint. The PMSC may also use the PCRF to modify the bearer. The PMSC then signals the MS to modify parameters for the established call. | 03-25-2010 |
20100097990 | METHOD AND APPARATUS FOR PROVIDING CIRCUIT SWITCHED DOMAIN SERVICES OVER A PACKET SWITCHED NETWORK - A method and Packet Mobile Switching Center (PMSC) for providing MSC-based services over a packet-switched network. An interface between a mobile station and the PMSC is used to transfer control plane and user plane information between the mobile station and the PMSC over the packet-switched network. In one embodiment, the PMSC includes a network controller for handling control plane information from a packet-switched core network and an interworking unit for handling user plane information from the packet-switched core network. | 04-22-2010 |

20100208624 | Response To CS Paging Request - A method and apparatus are provided for handling a paging request for a Circuit Switched session, when the paging request is intended for a terminal attached to a Packet Switched cell in a radio access network and having one or more ongoing Packet Switched sessions. The request is received at a node in the radio access or core network to establish a Circuit Switched session with the terminal whilst the terminal has one or more ongoing Packet Switched sessions. The importance of the ongoing Packet Switched session is determined at the node, and the paging request is rejected if any of the ongoing Packet Switched sessions is more important than the Circuit Switched session. The node may be a MME, an eNodeB or the terminal itself. | 08-19-2010 |
