Abstract: A method and apparatus for selecting a radio access network cell for connecting to a communications network. A client device that is connected to a Wi-Fi access network cell sends a request message to a node in the Wi-Fi access network cell. It receives a response from the node that includes information identifying at least one overlapping radio access network cell and a property of the overlapping radio access network cell. On the basis of a comparison between the property of the radio access network cell and a corresponding property of the Wi-Fi access network cell, the node determines whether to remain connected to the Wi-Fi access network cell or to move to the radio access network cell. This has the advantage that a client device that is already associated with a Wi-Fi AP can determine if another access network cell could provide it with a better service, for example if the conditions of the AP change dynamically.

Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a method and apparatus for protecting a core network (102) by receiving (202) a message (302, 402) containing a mobile identity of a MS (104) and dropping (210) the message (302, 402) whenever the received mobile identity does not match a stored mobile identity associated with the MS (104). The message (302, 402) is processed (208) whenever the received mobile identity matches the stored mobile identity associated with the MS (104). The mobile identity can be an IMSI, a TMSI or a P-TMSI. The message (302, 402) can be an uplink message (302) or a downlink message (402), such as a Mobility Management (MM) message, a General Packet Radio Service (GPRS) Mobility Management (GMM) message, or a UMA or Unlicensed Radio Resources (URR) message. The present invention can be implemented as a computer program embodied on a computer readable medium wherein the various method steps are implemented by one or more code segments.

Abstract: A method and radio network controller (RNC) in a radio access network (RAN) for controlling access to a cellular telecommunication system. Upon receiving an access request from a given user equipment (UE) through a given radio base station (RBS), the RNC retrieves authorization information from an access control database within the RAN. The authorization information indicates whether the given UE is authorized to access the system through the given RBS. The RNC alternatively grants access or denies access to the UE based on the retrieved authorization information. The RBS is particularly useful for controlling access through small cells with limited capacity.

Abstract: A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN triggering initiation of the packet-switched handover from the GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.

Abstract: 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 while 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.

Abstract: 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.

Abstract: A method for a cellular network (100) comprising cells (110) of a first kind controlled by corresponding base stations (111), and cells (120-122) of a second kind controlled by corresponding base stations (125-127). The second kind of cells are smaller than the first kind of cells (110). The network (100) comprises functions (140) for control of the base stations, and functions (150) for handing over the control of user terminals (123, 112) between base stations. The method is used when a call in a cell of the second kind (120-122) is handed over to a base station of the first kind. The method lets said control function (140) of the base station of the cell of the second kind send identifying information to the control function (140) of the base station (111) of the first kind, such that if the call is to be handed back to the original base station (125-127), the original base station can be found by the network.

Abstract: 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.

Abstract: An unlicensed-radio access network is connected to a core network portion of a licensed cellular mobile network and includes a broadband network (302) with a plurality of access points (301) each defining a mini-cell and adapted to communicate with mobile stations located within a mini-cell over an unlicensed-radio interface. An access controller (303) is connected to the core network portion and to the broadband network. In accordance with the invention, the access controller (303) is associated with its own location area or areas in the licensed radio mobile network and comprises a database for storing the identification of mobile stations in association with at least one specific access point or broadband network address. This arrangement permits a mobile station to be locating within the access network in response to a paging signal from the core network without undue signalling load.
