The method comprises determining a CLC characteristic between a first and second of the cells. The determining is based on a cell load contribution that is dependent on a measure of: a signal received by a receiving node of the first cell from a transmitting node of the first cell, a signal received by the receiving node from a transmitting node of the second cell, and traffic between the receiving node and the transmitting node of the first cell. One or more network management functions may be performed on the RCN based on the determined CLC characteristics. The method and/or the functions may be implemented by a computer program, a wireless communications device or a network node.

  • Patent number: 9173150
    Abstract: A user equipment for handling a cell change from a first cell to a second cell in a wireless communications network alters a duration of a measurement time over which at least one measurement is performed and alters a measurement bandwidth of the at least one measurement. The alterations may be performed based on associated bandwidths of the first and second cells. A network node sends, to the user equipment, a notification of a cell change and information associated with the cell change and also receives measurement data of at least one measurement performed over an altered measurement bandwidth and an altered duration of measurement time where the alterations are based on the information associated with the cell change.

  • Patent number: 9148795
    Abstract: Reporting methods well suited for reporting control information in a wireless system are described. A wireless terminal reports information to a serving base station, e.g., a base station attachment point, according to a reporting schedule. The reporting schedule includes a plurality of different types of fixed type information reports which communicate information of a type dictated by the reporting schedule. The reporting schedule also includes flexible reports at predetermined locations within the reporting schedule. The wireless terminal selects the type of report to be communicated in the flexible report, e.g., as a function of a report prioritization operation. Information identifying the wireless terminal's report type selection for the flexible report is jointly coded along with the report body information and communicated in the same dedicated control channel segment. The reporting schedule repeats over time.

  • Patent number: 9144101
    Abstract: An apparatus and method for improving the connectivity when a radio link failure occurs is disclosed. The method includes detecting, by a user equipment (UE), a radio link failure to a first radio network controller (RNC) and receiving an information message from a second RNC. The method further includes determining whether the first and second RNCs have interface connectivity between them. If the first and second RNCs have interface connectivity between them, performing a connection recovery procedure with the second RNC. However, if the first and second RNCs do not have interface connectivity between them, performing an initial connection procedure to establish a connection with the second RNC without performing a connection recovery procedure.

  • Patent number: 9118408
    Abstract: Methods and apparatus for improving operational and/or cost performance based on filter characteristics. Existing schemes for measuring filter performance are based on a worst case filter performance across a range of frequencies and temperature. Filter performance can be more accurately characterized over one or more frequency ranges. In one exemplary embodiment the frequency is characterized according to a functional (e.g., linear-average) metric. By providing more accurate representation of the reception/transmission filter performance, both network and device optimizations can aggressively manage available power and handle smaller (tighter) margins.

  • Patent number: RE45671
    Abstract: A converged IP messaging client transmits a session establishment request for interactive message communication. When a converged IP messaging server receives the request, it determines whether a target client of the interactive message communication uses a converged IP messaging service. If not, the converged IP messaging server transmits the session establishment request to an IWF. If it is determined that the target client is an SM client, the IWF generates an interactive message communication request by transforming a format of the session establishment request into an SMS format and transmits the interactive message communication request to the SM client. If the IWF receives an acceptance response from the SM client in response to the interactive message communication request within an effective response time, a session for the interactive message communication can be established between the converged IP messaging client and the SM client.
