  • Method and Arrangement in a Telecommunication System
    Publication number: 20230217243
    Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

  • Replay protection for resume procedure
    Patent number: 11696127
    Abstract: A communication system for resuming a connection comprises a user equipment (UE) and network nodes. A first network node is configured to prepopulate a UE context, and send, to a second network node, the UE context. The second network node is configured to receive, from the first network node, the UE context, and send, to a UE, a resume request message including a freshness parameter and the UE context. The UE is configured to receive, from the second network node, a resume request message including the freshness parameter and the UE context, generate an authentication token based on the freshness parameter and the UE context, and send, to the second network node, a resume response message including the authentication token. The communication system provides a freshness parameter and a prepopulated UE context to secure and facilitate resume procedure against replay attacks.

  • Transport Layer Handling For Split Radio Network Architecture
    Publication number: 20230209622
    Abstract: A radio network equipment central unit (20, 1700) receives a message (15) that indicates an update to a transport layer address of a radio network equipment distributed unit (10, 1600) from an old transport layer address (12A) to a new transport layer address (12B). The message (15) indicates the old transport layer address (12A) and indicates the new transport layer address (12B). The message (15) may be received from the radio network equipment distributed unit (10, 1600), or from a distributed unit of an integrated access backhaul donor. Regardless, for each of multiple user plane bearers or transport layer tunnels that are associated with the old transport layer address (12A), the radio network equipment central unit (20, 1700) may update a transport layer address of that bearer or tunnel from the old transport layer address (12A) to the new transport layer address (12B).

  • User equipment, network node and methods in a wireless communications network
    Patent number: 11678236
    Abstract: Methods, User Equipment (UE), and source network node for resuming a Radio Resource Control (RRC) connection to a target cell in a wireless communications network. 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 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.
