  • Patent number: 10194376
    Abstract: The present disclosure relates to a method in a radio access controller in a first radio access network for providing access control in a wireless network comprising the first radio access network arranged to operate according to a first radio access technology and a second radio access network arranged to operate according to a second radio access technology. The method comprises the steps of receiving an access request (Si3, Si4) originating from a wireless device, said access request comprising wireless device related information including information related to a global cell identity; assessing (P4) the access request based on the received wireless device related information, a throughput related value for the first radio access technology and a throughput related value for the second radio access technology, and responding (Si5, Si6) to the access request based on the assessment.

  • Publication number: 20180109977
    Abstract: A network node, a network control node and methods therein for achieving load based signaling. The method performed by the network node includes determining a load level out of a set of predefined load levels based on a current load of the network node, where each load level corresponds to an estimated capability of the network node to handle signaling from at least one network control node. The method further includes indicating the determined load level to at least one network control node, thus enabling the at least one network control node to apply a signaling handling scheme towards the network node based on the indicated load level.

  • Patent number: 9848368
    Abstract: A method in a first network node for handling traffic tracing of a user equipment. The first network node is comprised in a first Radio Access Technology, RAT, system. The first network node starts a handover procedure to handover the user equipment from the first RAT system to a second RAT system. The user equipment has an active traffic tracing ongoing in the first RAT system. The traffic tracing relates to tracing associated with communication between the user equipment and the first RAT system. The first network node sends a message to a second network node in the second RAT system. The message is sent directly to the second network node or via one or more intermediate network nodes. The message comprises one or more parameters relating to the ongoing traffic tracing of the user equipment. The parameters define when the traffic tracing is to continue in the second RAT system.

  • Patent number: 9179348
    Abstract: The invention relates to a method in a first radio base station for determining a performance state of a first cell served by the first radio base station, which first radio base station is comprised in a radio communications network. The method comprises determining traffic statistics of the first cell, comparing the traffic statistics with a threshold value, when the determined traffic statistics goes beyond the threshold value, transmitting a data request to a second radio base station requesting data retrieved in or associated with a second cell to be used to determine performance state of the first cell, receiving a data response indicating the requested data from the second radio base station, and determining the performance state of the first cell based on the data response.
