  • Providing communication for a mobile communication device using a central unit node and distributed unit nodes
    Patent number: 10674426
    Abstract: A method may be provided to operate a CU node that is coupled with first and second DU nodes. Communication is provided between the CU node and a mobile communication device through the first DU node over a first radio link. A message is received at the CU node from the first DU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication between the CU node and the mobile communication device through the first DU node is suspended, wherein configuration of the first DU node to serve the mobile communication device using the first radio link is maintained. While suspending communication between the CU node and the mobile communication device through the first DU node, communication may be provided between the CU node and the mobile communication device through the second DU node over a second radio link.

  • Small Data User Plane Transmission for Cellular Internet of Things (CIOT)
    Publication number: 20200170071
    Abstract: Exemplary embodiments include methods performed by a cellular Internet of Things, CIoT, user equipment, UE, for transmission of data in a communication network comprising a radio access network, RAN, and a core network, CN. Embodiments include sending, to an Access and Mobility Management Function, AMF, a request to establish a small-data user-plane, SDUP, data session. Embodiments can also include receiving a response indicating that the requested SDUP data session is established. The response can include an identifier associated with a user-plane function, UPF, within the CN, that supports the established SDUP data session. The response can also include an SDUP security configuration for communication between the UE and the CN during the established SDUP data session. Embodiments can also include subsequently communicating user data, associated with the established SDUP data session, with the UPF via a serving node in the RAN.

  • Method for avoiding unnecessary actions in resume procedure
    Patent number: 10667185
    Abstract: A method for avoiding unnecessary actions in a connection establishment comprises sending a request to a network node to initiate the connection establishment, upon sending the request to the network node, starting a timer for the connection establishment, wherein an expiration of the timer stops the connection establishment for a user equipment (UE), and stopping the timer to stop the connection establishment upon the UE receiving a suspend message or a release message, or upon the UE performing a cell reselection procedure while the timer is running. The timer may prevent the UE from waiting the connection establishment to be completed if there is an error or bad transmission in the connection establishment. Furthermore, the timer to stop the connection establishment may avoid unnecessary actions and inform other layers in the network when the timer expires to stop the connection establishment.

  • RESUMING A CONNECTION IN A WIRELESS COMMUNICATION SYSTEM
    Publication number: 20200163149
    Abstract: A user equipment is configured to receive, from a source radio access network, RAN, node with which the user equipment has a connection, a message indicating that the connection is to be suspended and indicating a resume identifier usable by the user equipment to resume the connection after the connection is suspended. While the connection is suspended, the user equipment is configured to transmit to a target RAN node a request to resume the connection. The request includes the resume identifier. The user equipment is also configured to transmit to the target RAN an indication of a public land mobile network, PLMN, with which the resume identifier is associated. Alternatively or additionally, the user equipment is configured to receive a paging message that includes the resume identifier and that indicates the PLMN associated with the resume identifier.

  • SECURITY HANDLING FOR RRC RESUME FROM INACTIVE STATE
    Publication number: 20200162897
    Abstract: Methods are provided for a User Equipment, UE, in NR RRC to revert back to an old security context if an RRC Resume procedure from an inactive state fails. In this way, any subsequent Resume attempts by the UE will derive new security keys from the old keys, which means that the keys and security context will be the same for each attempt. In this way, the security context in the UE will remain synchronized with the network security context, regardless of how many attempts the UE has performed (assuming the network does not change the security context when the Resume procedure fails). Alternatively, the UE may store the new security context it derives during the first Resume attempt, and then ensure that it is reused at subsequent Resume attempts.

  • Technique for controlling radio access nodes
    Patent number: 10652904
    Abstract: A technique for controlling a cluster of radio access nodes for radio communication with a user equipment is described. As to a method (200) aspect of the technique, information is received (202) from at least one of the user equipment and the radio access nodes, wherein the information is the cluster indicative of a radio quality (904-908) of the radio communication. Based on the received information, a number of radio access nodes that redundantly communicate with the user equipment is changed (204).

  • Handling of parameters provided in release / suspend
    Patent number: 10652948
    Abstract: New Radio (NR) RRC includes an RRC_INACTIVE state, which introduces ambiguities in the network's knowledge of UE behavior. A mechanism is introduced for handling parameters received when a UE enters RRC_INACTIVE upon the UE attempting to resume an RRC connection and, as a response, receiving a Release or Suspend message. The timer associated to the mobilityControlInfo (equivalent to T320) is stopped and associated parameters discarded upon receiving RRC Release or Suspend. Information received in a Release or Suspend message is discarded upon receiving RRC Release or RRC Suspend.

  • MULTI-CELL REGISTERED RADIO CONNECTION IN CELLULAR NETWORK
    Publication number: 20200145887
    Abstract: A radio device configures a radio connection between the radio device and a cellular network. The radio connection is registered for a cell area comprising at least a first cell and a second cell of the cellular network. Before a decision of the radio device to perform a change from the first cell to the second cell, the radio device determines a configuration which enables performing allocation of radio resources to the radio device via a control channel of the second cell. After the change of the radio device from the first cell to the second cell, the radio device resumes transmission on the radio connection by requesting allocation of radio resources of second cell based on the determined configuration.

    Publication number: 20200120470
    Abstract: Methods, a core network node (104A) and a node (102A) in a radio access network, RAN, (102), for enabling emergency services for wireless devices in the RAN. The core network node (104A) sends (2:1), to the RAN node (102A), information about one or more Access and Mobility Management Functions, AMFs, that support emergency services, to avoid an emergency fallback procedure for wireless devices in the RAN. The RAN node (102A) then selects (2:2) an AMF (104B) that supports emergency services for a wireless device (100) in the RAN, based on the received information. Thereby, the wireless device will have immediate access to emergency services and no delaying emergency fallback procedure is performed which could be critical in an emergency situation.
