  • Patent number: 11190243
    Abstract: A control device for a wireless communication system is configured to obtain a first channel estimation for a first client device and a second channel estimation for a second client device, to allocate a common resource block (RB) for concurrent wireless transmission between a first network node and the first client device using a first radio access technology (RAT) and between a second network node and the second client device using a second RAT based on the first channel estimation and the second channel estimation. The control device is further configured to allocate a first precoder for the common RB for the first client device and a second precoder for the common RB for the second client device. The first precoder and the second precoder are configured for spatially multiplexing the concurrent wireless transmission.

  • 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: 9872221
    Abstract: A method to be utilized in cell reselection in a mobile communication network offers a cell reselection mechanism based on absolute priorities. The mobile terminal measures several characteristics of a radio channel. The mobile terminal is configured to determine for each of the cells if the characteristics of the radio channel meet corresponding predetermined criteria compared to the received threshold values, and in response to outcome of the comparison determining at least one radio channel for reselection of a cell. A mobile terminal and a system for implementing the method are also described.

  • Patent number: 9802565
    Abstract: The present disclosure relates to a method for operating a safety system of a vehicle, which safety system comprises a remote sensor, an impact sensor and a protection system adapted to be activated by the impact sensor. The method includes scanning a selectable region in front of the vehicle by means of the remote sensor, determining that the selectable region provides a free path for the vehicle based on information from the remote sensor, and lowering a sensitivity of the impact sensor. The disclosure further relates to the safety system and a vehicle comprising the safety system.

  • Patent number: 9474071
    Abstract: The invention relates to a method and apparatus. In the method, an apparatus, for example, a base station, receives radio interface capabilities from a mobile node. The apparatus receives a subscriber frequency band priority profile identifier from a mobility management entity node. The apparatus finds an entry from a frequency band priority data structure using the subscriber frequency band priority profile identifier and the at least one radio interface capability and obtaining at least one frequency band priority from the entry. The apparatus applies the at least one frequency band priority to control the mobility of the mobile node.

  • Patent number: 8165587
    Abstract: A cellular radio communications network includes a core network coupled to a radio access network (RAN) that has multiple RAN nodes for communication with mobile radio terminals. Each of the multiple RAN nodes serves one or more cells. At least one cell associated with a first RAN node is in a restricted or reserved access state in which access to the one cell is restricted for at least some mobile radio terminals. The first RAN node sends a message to a second RAN node to inform the second RAN node of that restricted access cell. The fact that the restricted status of the one cell has changed is detected. A global message tha is not related to a specific mobile terminal is generated that includes information that the restricted status of the one cell has changed. The first RAN node sends the global message to the second RAN node to inform the second RAN node of the change in the restricted status of the one cell.

  • Patent number: 7894338
    Abstract: In a method of sharing a Radio Access Network, RAN, in one or more areas by at least two operators the determination whether to grant admission or not of a User Equipment, UE, to the RAN is performed in an admission control algorithm. A Radio Network Controller, RNC, is reading Network Resource Identifier, NRI, information contained in an “Initial Direct Transfer” message sent by the UE when requesting a service, and the read NRI information is used in a service admission control to check a plurality of service admission parameters as a part of a set of admission control parameters to grant or reject the requested service depending on whether the operator associated with the NRI has invested in needed technology or not. A corresponding radio access network comprises admission control means to determine whether to grant admission of a User Equipment, UE, to the network, RAN, or not.

  • Publication number: 20090117897
    Abstract: Methods and apparatuses for automatically determining neighbor cells are disclosed. Cell information is received. The received cell information is compared with a list of old neighbor cells. When a new cell is detected, a determination is made as to whether the detected new cell covers the same geographical area as any of the old neighbor cells. When the new cell covers the same geographical area as at least one of the cells of the list, the new cell is stored as a neighbor cell in the list. Cell information is received. The received cell information is compared with a list of old neighbor cells. New neighbors are detected based on the comparison. A determination is made as to whether there are cells in a same geographic area as the new neighbors. A determination is made as to whether there are new cells in a same geographic area as the old neighbor cells. The new neighbors, the cells in the same geographic area as the new neighbors, and the new cells are stored as neighbors in the list.
