  • Patent number: 10348601
    Abstract: A method for managing active measurements for determining performance parameters in a communication network comprises obtaining of a maximum permitted subsession duration and obtaining of time margins. The method further comprises determining whether or not a critical resource involved in the active measurement is active due to other activities than active measurements. If the determination concluded that the critical resource is active, a sending of an ensemble of packets of a subsession of an active measurement session is initiated. If there is an intended next subsession of the active measurement session and if a time since a last ensemble of packets was sent exceeds a sleep-init time comprised in the time margins, at least the determining and, if permitted, the initiating a sending of an ensemble of packets of the next subsession of the active measurement session is repeated.

  • Patent number: 9661537
    Abstract: Method and arrangement in a network control node, for performing access control of a mobile node in a handover from a source cell to a target subscriber group cell. The method comprises obtaining a network based allowed subscriber group list, receiving a target subscriber group identification, checking if the target subscriber group identification is comprised in the obtained network based allowed subscriber group list. If it is, information from a target network control node is obtained, verifying that the received subscriber group identification corresponds to the target subscriber group cell. Still further, the method comprises granting the mobile node access to the target subscriber group cell. Also, a method and arrangement in a target network control node, for assisting a network control node in performing access control for a mobile node in a handover from a source cell to a target subscriber group cell is provided.

  • Patent number: 8670342
    Abstract: A method and arrangement in a data collection network node (130, 140) for gathering information to be used for identification of at least one primary tracking area associated with a user equipment and a method and arrangement in a core network node (101) for selecting at least one tracking area identity identifying at least one tracking area to be used as at least one primary tracking area for a UE are provided. A tracking area identity is retrieved. Information about usage of a tracking area identified by the retrieved tracking area identity is registered. A measure for the user equipment being located in the tracking area is determined. Said at least one tracking area identity identifying at least one tracking area to be used as a primary tracking area is determined, if the measure exceeds a threshold. A method and an arrangement in a second network node (130) for paging a user equipment are provided.

  • Patent number: 8437743
    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.

  • Patent number: 8108903
    Abstract: The present invention relates to an arrangement and a method respectively for providing an end user with access to an IP network (login). It comprises a user station, an access server of an access network, a web server and an authentication server. The end user station comprises first means for communication with the access server and second means for communication over a mobile telecommunication system with the authentication server. The access/login procedure comprises a first and a second phase, the authentication server controls the first phase comprising a one-time-password (OTP) login sequence, and, if the one time password (OTP) is valid, the second login phase is performed in order to login the end user at the access server, by creating a temporary account for which user credentials are defined.

  • Publication number: 20110176531
    Abstract: The present invention relates to methods and devices that allow for efficient transportation of traffic in conjunction with a home base station (1). Traffic arriving in the home base station from a mobile terminal (2) connected to the home base station can be transported by means of local breakout transportation, which implies that the traffic is forwarded to a local node (4) over a local network (20) or to the Internet (21) without passing a core network (15) of a mobile telecommunications system. A local breakout bearer (22) is established, which is a radio bearer that extends between the mobile terminal and the home base station. The mobile terminal forwards uplink traffic that is to be subject to local breakout transportation to the home base station on the local breakout bearer. Thus it is not required for traffic that is destined for local nodes or the Internet to pass the core network, which allows for efficient traffic forwarding.

  • Publication number: 20110009113
    Abstract: The embodiments of the present invention relate to an apparatus and a method of controlling access of a UE (30, 40) in a wireless telecommunications system comprising a RAN that is adapted to communicate with the core network (34, 44). According to the method, a temporary identity of the UE (30, 40) attempting to accessing a femto RBS (31, 41) is acquired and it is further determined if the temporary identity of the UE (30, 40) is associated with a permanent identity of the UE and at least the identity of the femto RBS. In case the temporary identity is associated with the permanent identity of the UE (30, 40) and with the identity of the femto RBS, the UE (30, 40) is authorized access, otherwise it is denied access.

  • Publication number: 20100075698
    Abstract: Methods and apparatus are provided for operating a telecommunications network (20) which comprises at least one femtocell and at least one macrocell, each femtocell and each macrocell being associated with a Tracking Area. The method comprises (when a wireless terminal (30) accesses a femtocell or possibly a cell in the vicinity of the femtocell) including an identifier of the femtocell in a Tracking Area Identity list provided to the wireless terminal (30), and thereby enabling the wireless terminal (30) to avoid performing a Tracking Area Update when moving between the femtocell and another tracking area included in the Tracking Area Identity list. The method also comprises (when the wireless terminal (30) is to be paged) initially issuing a paging message only to a portion of the cells having corresponding identifiers included in the Tracking Area Identity list.
