Abstract: A method and an OCA module of a radio network node (RNN) for handling a request for at least one channel and a method and an OCA module of a core network node (CNN) for providing at least one channel operable by a RNN are disclosed. The OCA module receives, from an RMM module, the request. The OCA module sends, to the OCA module of the CNN, the request and a set of local parameters. The OCA module of the CNN assesses channels to select one or more channels in a first level assessment, wherein the assessment is based on the set of local parameters and a set of global parameters. The OCA module of the CNN sends the one or more channels to the OCA module. The OCA module assesses, in a second level assessment, said one or more channels, to obtain at least one second level channel.

Abstract: A system, method, and apparatus for managing interference are presented. The interference may be between i) a fixed wireless link, FL, formed by a first FL node and a second FL node which communicate at a frequency f1 and ii) a radio access network, RAN, node. The method may comprise the first FL node monitoring radio link quality, QL, of fixed wireless link signals at f1. The first FL node may determine whether QL is worse than a predetermined QL threshold. If QL is worse than the predetermined QL threshold, the first FL node may measure, during a silent period, how much one or more signals transmitted from the RAN node 108 interferes with the first FL node at the f1. The first FL node may transmit, to an interference mitigation controller, interference measurement information which indicates how much the RAN node interferes with the first FL node at f1.

Abstract: Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller and radio resource manager. A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager, which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.

Abstract: Methods, apparatuses, and computer program products provide for routing information between nodes of a radio network. A quality metric is received at a network node that indicates a quality of at least one channel of a plurality of channels in the network. A virtual network is generated that includes one or more routes between a source node and a destination node. A modified virtual network is generated based at least in part on the quality metric and the virtual network, and is then used to determine an optimized route between the source node and destination node. The determination includes a joint selection of one or more of a plurality of network nodes and the plurality of the channels.

Abstract: Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller (210) and radio resource manager (220). A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager, which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.

Abstract: The proposed technology relates to methods, devices and network nodes for enabling mitigation of interference between an External Wireless System, EWS, and a mobile communication system. For example, a UE may detect (S1) an EWS event involving EWS operation interfering with the operation of the mobile communication system provided at least one interference condition is fulfilled. The interference condition(s) includes a first condition based on a frequency relation between a representation of an operating frequency of the EWS and a representation of a reference frequency. The UE may then enable (S2) the mitigation of interference based on event information representing the EWS event.
