  • Patent number: 9961596
    Abstract: A method for determining a capability of a user equipment. The user equipment is served by a non-shared network in a first place. The non-shared network is configured to transmit a message to the user equipment, the message including information on at least two PLMN identities. The user equipment is configured to deliver a response message from which it is determined if the response message includes information field reserved for at least one PLMN identity in the transmitted message. On a basis of an existence of the information field in the response message it can be determined that the user equipment supports network sharing. In other case it is determined that the user equipment is not supporting network sharing. A network node and a system implementing at least part of the method are also described.

  • Patent number: 9462516
    Abstract: A Network node provides information to a base station indicating a list of forbidden frequency from which the base station may or may not offer services. The base station checks the received list of forbidden frequencies when considering whether to provide service to user equipments from a new tracking area or a certain access technology. The base may also transmit a list of allowed frequencies or the list of forbidden frequencies to user equipments to be used thereof. By introducing the possibility to set an amount of frequencies as forbidden in the area and access restriction information of user equipments, operators would be able to offer services like home base station in a simple way to customers.

  • Patent number: 9204313
    Abstract: The invention relates to a method in a first communication node in a wireless communications network comprising a plurality of second communication nodes for enabling a central processing of local data from second communication nodes in the network. The first communication node establishes (82) an intemode connection in a radio access network of the wireless communications network to a second communication node wherein information is sent of a virtual cell of the first communication node. The first communication node then requests (84) and receives (86) local information from the second communication node. The received local information is then processed (88) into processed data to be used to centrally process the local information of the second communication node. For centrally processing the local information, the processed data is transmitted (90) to a third communication node.

  • Patent number: 9049624
    Abstract: A method where a first type location area of a mobile node is registered to a first mobility management node. A second type location area is determined based on a location of the mobile node. A second type location area of the mobile node is registered to a second mobility management node of a second system. A request to perform user plane bearer establishment through the second system is received. Thereupon, radio measurements associated with at least two candidate cells are obtained from the mobile node. Candidate cells are searched to find at least one cell associated with the second type location area. A cell is selected among the at least one cell, which is indicated to the selected cell to the mobile node. A handover request is provided to the mobile node.

  • Patent number: 8660009
    Abstract: A cellular radio communications network includes a core network with a core network node coupled to a radio access network (RAN) associated with a first radio access technology for communicating with mobile radio terminals. The RAN includes multiple RAN nodes. Each mobile radio terminal has an associated access class for accessing service from the cellular radio communications network. The core network node detects an overload condition and sends an overload message to the RAN nodes that includes information for reducing the overload condition. Each of the RAN nodes receives the overload message and determines whether an access class restriction should be implemented to reduce the number of mobile radio terminals permitted to access the cellular radio communications network. If so, the RAN node determines one or more access classes of mobile radio terminals to be restricted based on the information in the overload message.
