  • Resume in Paging
    Publication number: 20220264518
    Abstract: A wireless device performs a method for resuming a Radio Resource Control, RRC, connection. While in a power saving state, the wireless device monitors a paging 5channel. When the wireless device receives a paging message on the paging channel, it determines whether the paging channel includes a message enabling the wireless device to resume the RRC connection. If the paging channel includes a message enabling the wireless device to resume the RRC connection, the wireless device performs actions determined by said message.

  • User equipment, network node and methods in a wireless communications network
    Patent number: 11399322
    Abstract: Methods, User Equipment, UE, (120) and source network node (111) for resuming a Radio Resource Control, RRC, connection to a target cell in a wireless communications network (100). The UE generates a security token using a set of input parameters, and sends a resuming request with the security token to a target network node (112) serving the target cell. When receiving the resuming request, the source network node generates a security token using a set of input parameters in the same manner as the UE. If the received security token is successfully verified when compared with the generated security token, the source network node provides to the target network node a UE context of the UE, to enable the target network node to resume the RRC connection.
