Abstract: An approach for enhancing service continuity in the case of a communication failure between a repository and a controller of a spectrum sharing communication system as described. The repository is operable to at least one of store and generate restrictions governing use of a set of spectrum resources, and the controller is operable to receive the restriction from the repository and to enforce the restrictions A method implementation performed, for example, by the controller may comprise determining occurrence of a communication failure between the repository and the controller and, in response to the communication failure, taking one or more actions that result in an at least temporary continued use of spectrum resources under control of the controller.

Abstract: A method for forwarding a page message to a communication device includes receiving a page message and a list of Closed Subscriber Group (CSG) Identities in conjunction therewith. Each of the CSG Identities is indicative of which radio base stations among said plurality of radio base stations the communication device is allowed to access. The method also includes selecting, based on the list of CSG Identities received in conjunction with the received page message, a subset of radio base stations among said plurality of radio base stations and forwarding the page message to each radio base station in the selected subset of radio base stations, whereby the communication device is paged only via radio base stations that the communication device is allowed to access.

Abstract: A technique for assigning spectral resources in a cellular network for wireless communications is described. The spectral resources are partly utilized by other applications. As to a method aspect of the technique, a controller (100) of the cellular network receives information (702) indicative of one or more geographical areas and restrictions within the one or more geographical areas (1002). The spectral resources are assigned based on the received information (702).

Abstract: Methods and systems described herein may provide for the updating, maintenance, and/or transference of a CSG White List that is stored on a user equipment. The CSG White List may be implemented to store information related to the access of CSG cells, such as, for example, femto cells. Additionally, methods and systems described herein may provide for the updating, maintenance, and/or transference of an access control database. The access control database may be stored in one or multiple devices in a communication system. The access control database may be implemented to store information regarding home nodes and which user equipment is allowed to access the femto cell or CSG cell provided by each home node.

Abstract: According to a first aspect there is provided a method of operating an entity of a Wireless Local Area Network (WLAN). The method comprises receiving a Media Access Control (MAC) address for a device that is attempting to associate with the WLAN (S101), and determining if an International Mobile Subscriber Identity (IMSI) associated with the MAC address is stored in the WLAN (S102). The method further comprises, if an IMSI associated with the MAC address is not stored in the WLAN, obtaining an IMSI for the device during authentication of device stored IMSI of the device to the WLAN (S103), and causing storage within the WLAN of the obtained IMSI in association with the MAC address (S104).

Abstract: The teachings herein provide authorization control enabling the co-existence of legacy mobile terminals (20) that do not support Closed Subscriber Groups (CSGs), and non-legacy mobile terminals (20) that do. New behaviors are defined for a CSG femtocell base station (10) (referred to as a Home NodeB or HNB), and for a base station gateway (14) (referred to as a HNB Gateway or HNB GW) that couples the HNB (10) to a Core Network (CN) (22). The HNB (10) and/or the HNB GW (14) determine whether a terminal (20) attempting to gain connection through the HNB (10) supports CSGs. If not, the HNB GW (14) performs access control and rejects the connection attempt if authorization fails. If the terminal (20) is recognized as supporting CSGs, the HNB GW (14) defers access control to the CN (22) by automatically accepting registration/connection requests from the HNB (10) for CSG-capable terminals (20). In such cases, the CN (22) is relied upon for access control, including any CSG authorization of the terminal (20).

Abstract: A system and method for detecting cooperation or conflict between actors in a network made up of self-organizing sub-networks examines parameters such as performance indicators and configuration parameters to determine whether or not different actors are adjusting configuration parameters in a way that is cooperative or conflicting. When a performance indicator is observed to be outside of its expected range, an acceptable convergence range can be defined to give the actors time to adjust and return the performance indicator to its expected range of values. When a performance indicator is detected to be non-convergent, the monitor can alert an operator, or another node, so that appropriate actions can be taken.

Abstract: In compression of packet data headers the compressor side (100) in a point-to-multipoint connection transmits (301) a message announcing a particular service. The entities (200) receiving the announcement message are adapted to respond to the message and based on the response message(s) (305) the compressor can adapt the compression scheme used. In particular the compressor may compress (315) or not compress (311) the header of the packet data header.

Abstract: The present invention relates to methods and arrangements for configuring the HeNB (Home eNode B) to retrieve location information indicative of its location and sending this location information via a core network node to a UE (User Equipment) authorized to access the HeNB. The UE can then based on this received location information and on a determination of the location of the UE determine whether the UE is being positioned in the coverage of the HeNB. This implies that the authorized UEs of the HeNB know when they should try to find and access the HeNB and the UEs may then avoid accessing the HeNB when it is out of the HeNB coverage which will save UE battery and reduce interference.

Abstract: The invention relates to a method in an Access Network Discovery and Selection Function, ANDSF, node for distributing Closed Subscriber Group information. The CSG information comprises an Allowed CSG List of a first UE and cell information indicating position of a cell with controlled access associated to the Allowed CSG List. The method comprises retrieving an Allowed CSG List of the radio cell from a CSG Database over a first network 10 interface (CSGi) between the ANDSF node and the CSG Database. Furthermore, the ANDSF node triggers the first UE to establish a connection to the ANDSF node over a second network interface (ANDSFi) between the ANDSF node (90) and the first UE. In addition, the ANDSF node receives cell information indicating the position of the cell with controlled access and the Allowed CSG List is sent to the first UE.

Abstract: An access node in the boundary area of a single frequency network service area transmits a boundary indication to the mobile terminals in the boundary area to notify the mobile terminals that they are approaching the boundaries of the single frequency network. The mobile terminals receiving the boundary indications may then take steps to maintain continuity of broadcast services when the mobile terminals leave the service area of the single frequency network.

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.
