  • Patent number: 10390253
    Abstract: A network node and a method performed by the network node for congestion control in a Radio Base Station, RBS, are provided. The method comprises determining that the RBS is congested. The method further comprises determining an interference level in a neighboring RBS caused by wireless devices currently being served by the RBS, or determining a level of inter-cell coupling between the RBS and the neighboring RBS. Still further, method comprises increasing a value of an average received signal level target, P0, for wireless devices currently being served by the RBS if the RBS is congested, if the determined interference level in the neighboring RBS is below an interference threshold or if the level of inter-cell coupling is below a coupling threshold.

  • Patent number: 10362516
    Abstract: Known HO performance indicators comprise Retainability Rate and HO Successful Rate. The Retainability Rate is defined as the ratio between abnormal connection releases and the total number of releases, and HO Successful Rate is defined as the ratio of successful HOs and the total number of HO attempts. The application proposes two new HO performance indicators LowCqiRateWhenHo (522) and LowUISinrRateWhenHo (524). These two HO performance indicators are based on radio link conditions before a HO for the DL and UL channels respectively. The indicator LowCqiRateWhenHo is defined as the ratio of low, i.e. below a threshold (514). CQI measurement samples of users (502) just before a HO and is as a measure of DL connection quality during HO. The indicator LowUISinrRateWhen Ho is defined as the ratio of low, i.e. below a threshold (516). SINR measurement samples (506) in UL just before a HO and is as a measure of UL connection quality during HO.

    Abstract: A network node and a method performed by the network node for congestion control in a Radio Base Station, RBS, are provided. The method comprises determining that the RBS is congested. The method further comprises determining an interference level in a neighbouring RBS caused by wireless devices currently being served by the RBS, or determining a level of inter-cell coupling between the RBS and the neighbouring RBS. Still further, method comprises increasing a value of an average received signal level target, P0, for wireless devices currently being served by the RBS if the RBS is congested, if the determined interference level in the neighbouring RBS is below an interference threshold or if the level of inter-cell coupling is below a coupling threshold.

  • Patent number: 9282445
    Abstract: Concepts and technologies are disclosed herein for identifying backup coverage in wireless networks. An active network resource to be analyzed is identified, and a at least one potential backup network resource is identified. The at least one potential backup network resource is evaluated to determine if the at least one potential backup network resource is available to function as the backup coverage for the active network resource. If the at least one potential backup resource is available to function as the backup coverage for the active network resource, a power management parameter associated with the wireless networking environment can be updated.

  • Patent number: 9179386
    Abstract: Technologies are described herein for parameter optimization of at least one interlayer handover in a multilayer wireless cellular communication network. Performance information for the communication network is retrieved. The retrieved performance information for the communication network is then averaged over a predetermined period of time. A determination is made based on the performance information as to whether optimization of the communication network is required. If so, the interlayer handover is optimized by capturing a current set of configuration parameters for the interlayer handover, generating a new set of configuration parameters for the interlayer handover based on the retrieved performance information and the current set of configuration parameters, and applying the new set of configuration parameters to the communication network.

  • Patent number: 9066294
    Abstract: Technologies are described herein for real time event-driven automation of energy management features within a wireless communications network. Resources within a wireless communications network, such as entire base stations or equipment within a base station supporting specific cells, sectors, frequency bands, or services, may be switched on or off in response to events occurring within the communications network. A central controller receives a network interface message corresponding to an event occurring within the communications network. The central controller analyzes the network interface message and, based upon the analysis of the network interface message, generates an action message that includes instructions to take an action on an affected network resource within the communications network. The action message is then transmitted to the appropriate network resource.

  • Publication number: 20130067093
    Abstract: Concepts and technologies are disclosed herein for identifying a network resource in a wireless networking environment as essential. A network resource to be tested is identified. The network resource is transitioned to a softbar operation state. In the softbar operation state, use of the network resource is avoided. If access data indicates substantial use of the network resource, the network resource can be identified as essential.

  • Patent number: 8301156
    Abstract: Technologies for load balancing among neighboring cells of a mobile wireless communication network can reduce traffic congestion and improve network system capacity. Load balancing can be accomplished by adjusting various radio access network parameters. Such adjustments may be made at the cell level or at the neighboring cell level. The adjustments can be applied iteratively in response to various collected operational statistics. The adjustments can adapt cell size and cell shape as well as adapt handover to maximize system resource and hardware utilization. An iterative process of optimization can periodically collect performance statistics and network configuration from a mobile wireless network. The collected information can be periodically analyzed to determine parameter adjustments. Configuring additional capacity from the communication network can prevent or substantially delay the acquisition of additional hardware resources to mitigate system capacity issues.
