  • Patent number: 10582474
    Abstract: It is provided a wireless communication device adapted to employing a paging and/or tracking mode determined based on a motion state of the wireless communication device, a network entity adapted to determining a paging and/or tracking mode for the wireless communication device, and a method for paging and/or tracking a wireless communication device the wireless communication device being adapted to communicate with the network entity of a wireless communication network, and further adapted to evaluate, in the wireless communication device, a condition that indicates an in-motion or stationary state of the wireless communication device and transmit information for adapting a paging and/or tracking mode in the network, information indicating the in-motion or stationary state of the of the wireless communication device towards the communication network.

  • Patent number: 10547365
    Abstract: A radio network node (12) is configured to serve a wireless device (14) in a wireless communication system (10). The radio network node (12) in this regard is configured to determine that the wireless device (14) is onboard a public transit vehicle (16). Based on that determination, the radio network node (12) is configured to predict a position of the public transit vehicle (16), e.g., based on a route schedule (20) of the public transit vehicle (16) and/or positioning measurements (22) received from the public transit vehicle (16). The radio network node (12) is further configured to control beamforming for the wireless device (14) based on the predicted position of the public transit vehicle (16). In some embodiments, this controlling comprises performing dynamic beam direction adjustment, as needed to track the vehicle (16)'s movement.

  • Patent number: 10484965
    Abstract: A method and a vehicle as well as a method and a user equipment for enabling a network node to manage paging of the user equipment are disclosed. Moreover, a method and a network node for managing paging of a user equipment are disclosed. The user equipment sends, to the vehicle, an identification of the user equipment by use of a direct wireless communication connection. Then, the vehicle sends, to the network node, the identification of the user equipment. The network node sends, to the user equipment, a control message instructing the user equipment to apply a second DRX cycle, wherein the second DRX cycle is longer than a first DRX cycle. The network node also receives, from the vehicle, position information of the vehicle, whereby the network node, upon paging of the user equipment, sends a paging message, based on the position information of the vehicle, to the user equipment. Corresponding computer programs and carriers therefor are also disclosed.
