  • Patent number: 9596698
    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.

  • Patent number: 9532283
    Abstract: A telecommunications system comprises a serving radio base station and a candidate radio base station which are different with respect to at least one of frequency and radio access technology. The serving radio base station comprises a radio base station to which a wireless mobile station provides measurement reports. A method comprises the serving radio base station allowing the mobile station to obtain information broadcasted by the candidate radio base station. The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station or the Cell Global Identity (CGI) itself of the radio base station. The mobile station obtains the information from the candidate radio base station during at least one reading gap. The reading gap is a time period in which the mobile station does not receive information from the serving radio base station.

  • Patent number: 9461886
    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.

  • Patent number: 9408107
    Abstract: In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level (130-133) 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 (130-133). Communication utility can preferably be maximized 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: 20160183099
    Abstract: Some embodiments provide a method for performing cell reconfiguration in a network node, which is associated with at least two antennas. Each antenna is capable of transmitting a signal covering at least one sector. The method comprises switching (1212) from a first state (1210) wherein a multi-sector cell covering at least two sectors is active, to a second state (1220), wherein sector cells covering each of the at least two sectors are active in addition to the multi-sector cell. In the second state, the same antennas are utilized for the sector cells as for the multi-sector cell. The method further comprises switching (1222) from the second state to a third state (1230) wherein the multi-sector cell is deactivated and the sector cells are active.

  • Patent number: 9241280
    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.
