  • Patent number: 10194376
    Abstract: The present disclosure relates to a method in a radio access controller in a first radio access network for providing access control in a wireless network comprising the first radio access network arranged to operate according to a first radio access technology and a second radio access network arranged to operate according to a second radio access technology. The method comprises the steps of receiving an access request (Si3, Si4) originating from a wireless device, said access request comprising wireless device related information including information related to a global cell identity; assessing (P4) the access request based on the received wireless device related information, a throughput related value for the first radio access technology and a throughput related value for the second radio access technology, and responding (Si5, Si6) to the access request based on the assessment.

  • Publication number: 20160269947
    Abstract: A wireless device for a cellular network comprises a receiver arranged to receive a request to report at least one second network cell suitable for handover, a processor arranged to determine the at least one second network cell suitable for handover among a set of available network cells and to form a response comprising a respective local cell identity associated with the at least one suitable second network cell, and a transmitter arranged to transmit the formed response. The processor is further arranged to determine a cell identity confusion risk involved for the set of available network cells based on information in the request and based on local cell identities associated with the set of available network cells, and measure a global cell identity for each at least one second network cell determined to be involved in a cell identity confusion risk.

  • Patent number: 9357454
    Abstract: Methods, user equipment (120) and target base station (130) for supporting update of neighbor cell relations in a cellular communications network (100). The user equipment (120) switches from being served in the source cell (115) by the source base station (110) to instead being served in the target cell (135) by the target base station. The user equipment sends (304, 403), to the target base station (130), in association with the switching, an identifier of the source cell (115) in the cellular communications network (100) and a request for mobility report. The request for mobility report requests the target base station (130) to send a mobility report to the source base station (110) or a management entity (140) thereof. The mobility report reporting that a successful switch has taken place between the source cell (115) and the target cell (135), thereby enabling updating of the neighbor cell relations based on the mobility report.

  • Patent number: 9301224
    Abstract: Disclosed is a method in a network node (106) for establishing neighbor cell relations in a wireless network for a source cell (107) served by the network node (106). The method comprises establishing (34) a temporary neighbor cell relation for a received unknown neighbor cell identification; verifying (36) validity of the temporary neighbor cell relation, and establishing (38) a permanent neighbor cell relation based on the established temporary neighbor cell relation, if the temporary neighbor cell relation is found valid, thus avoiding that a false neighbor cell identification results in a faulty permanent neighbor cell relation. Disclosed is also a corresponding apparatus in a network node for establishing neighbor cell relations in a wireless network.

  • Publication number: 20150172975
    Abstract: A controlling node (225) for a first cell (227) in a cellular network (200), arranged to receive measurement reports from User Equipments, UEs (230, 255), in the first cell (227) on the signal strength and/or signal quality of transmissions from the controlling nodes of neighboring cells (217), and to maintain a list of neighboring cells based on such measurement reports. The list shows how many of the UEs (230, 255) in the first cell (227) that each of said neighboring cell's (217) controlling node “covers”, i.e. reaches with a signal strength and/or signal quality above a certain level. The controlling node is also arranged to decide to perform blind handover or release with redirect on one of the UEs in the first cell, and to choose one or more of the cells in the list as the target cell or cells for blind handover or release with redirect.

  • Publication number: 20100319065
    Abstract: The invention is directed towards methods of configuring a firewall in a first base station (12) in a wireless wide area network (CN, RAN) as well as to a firewall configuring device (20) and a first base station (12). The first base station (12) obtains new neighbour base station data related to updating of a neighbour list of this first base station (12), which data includes data identifying a second base station (14) provided in the neighbourhood of the first base station. Based on the data the firewall configuring device (20) provides the first base station (12) with firewall configuration data including a second authentic logical address of the second base station (14), which authentic address is not provided in the neighbour list before the updating. The first base station (12) uses the firewall configuring data for updating its firewall in order to allow communication with the second base station (14).
