  • Publication number: 20150334566
    Abstract: There is provided a method of authenticating a public land mobile network (PLMN) to a mobile station (MS). The PLMN provides a circuit switched access network to the MS, and the MS and a trusted service, TS, have established a security context. The initiation of a voice call or initiation of sending or receiving of a pushed message by the MS (S10.1) is detected, and the TS generates a response authentication token using a session identifier and the security context (S10.7). The TS sends a response comprising the response authentication token to the MS such that the response is delivered to the MS over a signalling channel of the PLMN using a mobile subscriber integrated services digital network-number (MSISDN) associated with the subscriber or subscription to direct the message (S10.9). The MS authenticates the response using the response authentication token, the security context, and the session identifier (S10.12) in order to authenticate the PLMN.

  • Publication number: 20150043386
    Abstract: A set of reporting features are specified for implementation by lower-level Self-Optimizing Network (SON) functions to support the observation of network SON algorithms by high-level SON functions (e.g., OAM functions). The lower-level SON functions may be operative to adjust local parameters related to the network element serving area and/or capacity. The reported SON algorithm events and measurements can be defined such that they can be used by the higher-level SON function to resolve conflicts and control the lower-level SON functions. Some embodiments specify SON function reporting features and their configuration in the framework of the 3GPP defined Itf-N interface specification.

  • Publication number: 20150031361
    Abstract: The disclosure relates to a method and radio base station for sharing resources in a wireless communication system. The radio base station stores an identity of a first entity to which a first plurality of UEs is associated. The first plurality of UEs has full access to resources provided by the radio base station. The radio base station also stores an identity of a second entity to which a second plurality of UEs is associated. The second plurality of UEs has partial access to the resources provided by the radio base station. When the radio base station receives a request for accessing resources from a UE, it determines whether the UE is associated with the second entity, i.e. if the UE is to be handled in support mode. If the UE is associated with the second entity it means that the UE only should have partial access to the resources.

  • Publication number: 20140066074
    Abstract: A radio network node and method for improved control of handover decisions of a User Equipment (UE) in a wireless communications network. The UE is in a served cell and is moving towards a neighboring cell. The network node obtains neighboring cell characteristics and determines a mobility threshold based on the obtained neighboring cell characteristics. The handover decisions of the UE to the neighboring cell are then controlled based on the determined mobility threshold.

  • Publication number: 20140038630
    Abstract: A method in a first radio network node for testing a transmission parameter value in a wireless communication system is provided. The first radio network node is configured to, during operational mode thereof, perform transmissions using available resources divided in to resource blocks. The first radio network node allocates a test resource block, for test purposes, among the available resources. The first radio network node defines for the test resource block, a test value for the transmission parameter. The test value differs from the nominal value. The first radio network node performs, during operational mode, a test transmission using the resource block. During the test transmission, the transmission parameter is set to the test value. The test transmission is configured to form the basis for an evaluation of the test value.

  • Patent number: 8396480
    Abstract: In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level based on a determined load level (ULOCAL) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level. Communication utility can preferably be maximised or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided. This gives an opportunity to let particularly well-suited users still have access to the first access network. At the same time, since the preferred access is decided before the actual access attempt, control signalling can be significantly reduced, even at very high traffic loads.

  • Publication number: 20120302235
    Abstract: The present invention relates to a cellular communications network and in particular to the problem of identifying cells for neighbour lists, or handover candidates when the cells are identified by a limited number of non-unique identities. The present invention includes a method for a radio base station, wherein the base station receives reports from one ore more terminals in neighbour cells quality and non-unique identities. The match is sought in a neighbour cell list non-unique identity with a unique cell identity. If the match cannot be made without ambiguity, the base station orders the terminal to detect the unique cell identity. If the reason for the ambiguity is the particular cell is not included in the neighbour cell it is included when its unique identity has been established. The uniquely identified cell is used if a handover is decided.
