  • Patent number: 10313952
    Abstract: The invention relates to methods and arrangements for handling handover-related parameters. A radio base station of a mobile communications network is arranged to serve at least a first cell, and to make handover decisions based on handover-related parameters. The radio base station comprises means for receiving handover related feedback from a radio base station serving a second cell after handover of a UE from said first cell to said second cell; means for using the handover related feedback received from the base station serving said second cell to adjust the handover-related parameters; and further by means for sending handover related feedback to a radio base station serving a second or another cell after handover of a UE to said first cell from said second or another cell.

  • Patent number: 9992720
    Abstract: A method in a base station (110) for enabling the base station (110) to identify a neighboring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighboring base station (120). In response to reception of the sent identification requesting message, a neighboring base station identifier that is associated with and identifies the neighboring base station (120), is received (303). Thereby the base station (110) is enabled to identify the neighboring base station (120). By receipt of the neighboring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighboring base station more directly, without the need of doing it through the user equipment. This can be done at some later point in time, for example in order to request the neighboring base station to perform handover measurements with regard to the same or another user equipment.

  • Patent number: 9888400
    Abstract: A method in a radio network node is disclosed for handling positioning data in a radio communications network, which radio network node serves a user equipment in a cell. The radio network node obtains positioning data from the user equipment, which positioning data is associated with a positioning measurement for positioning the user equipment. The radio network node associates the obtained positioning data with an on-going trace session of the user equipment. The radio network node then sends a trace record to a network management node, which trace record includes information associated with the positioning data.

  • Patent number: 9866355
    Abstract: Methods, arrangement and network nodes for supporting inter-cell coordination of scheduling of radio resources subjected to inter cell interference. The methods involve identifying one or more radio resources which are subjected to inter-cell interference between a first cell and a second cell. The methods further involve deriving a respective service value related to service that could be provided in the respective first and second cell by use of the one or more radio resources. Further, transmissions in the one or more radio resources are controlled based on comparison of the service values, thus enabling inter-cell service value-based scheduling of the one or more radio resources, prioritizing services having the highest value per radio resource.

  • Patent number: 9743306
    Abstract: The invention relates to a method for performance reporting in a wireless network, wherein at least one terminal is associated to a terminal report server by means of information in the terminal. Prior to initiating the performance report, information on operator identity is retrieved. The operator identity is combined with information identifying the associated terminal report server to compile a fully qualified domain name. Connectivity information to the terminal server report is requested and received from a domain name server, whereupon a performance report session to the terminal report server is initiated using the received connectivity information. The invention also relates to a terminal wherein the inventive method is applied.

  • Patent number: 9692682
    Abstract: There is provided a method performed by a first network node (101) for handling handover failures for a target cell (112), which target cell is applicable for handover of a wireless device (121) in a wireless communications network (100) from a source cell (111) to the target cell. The target cell is associated (202) with an indication indicating that the target cell is unsuitable for handover, when an amount of failed handovers from the source cell to the target cell exceeds (201) a failure threshold.

  • Patent number: 9591534
    Abstract: Methods, network control nodes, network nodes and user equipments for assisting the updating of neighbor cell information when a new cell is introduced, or added, to an already existing radio access network are described in this disclosure. According to an example embodiment a signal is transmitted, from a first network control node 10 associated with RAN1 to a second network control node 20 associated with RAN2. This signal comprises a cell identity CI1, e.g. a Local Cell Identity LCI1, of the newly introduced cell C109, which is added to RAN1. Next, the second network control node 20 of RAN2 receives the signal comprising the cell identity CI1 of this newly introduced cell C109.

  • 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: 9516629
    Abstract: A method in, and a network node (110, 140), for supporting compensation of cell outage in a cellular communications network (100). The cellular communications network (100) comprises a compensating cell (135) for compensating the cell outage and a supporting cell (115) neighboring the compensating cell (135). The network node (110, 140) obtains (502, 1202) a sub-band of a system bandwidth for uplink scheduling of resources for the compensating cell (135). The network node (110, 140) schedules (503, 1203), in response to the cell outage, resources for the supporting cell (115) with restricted uplink scheduling within the sub-band. The network node applies (504, 1204) the scheduled resources in the supporting cell (115), thereby supporting the compensation of cell outage. As a result, higher Signal to Interference and Noise Ratio (SINR) is enabled in the uplink in the compensating cell. This may e.g.

  • 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.
