Abstract: A UE operating in a RAN may be configured to receive new radio, NR, radio resource control, RRC, messages from a secondary network node. The NR RRC messages may each contain a number that the secondary network node added to the NR RRC messages to indicate their respective order in a sequence which the NR RRC messages were sent by the secondary network node. The NR RRC messages may each contain parameters that the UE uses to configure its communications through a NR interface with the secondary network node. The UE may send NR RRC complete messages toward the secondary network node responsive to receipt of the NR RRC messages, wherein the NR RRC complete messages each contain an indication of the NR RRC message that was received. The UE may control the sending of the NR RRC complete messages to indicate to the secondary network node whether the NR RRC messages are received in an order that is the same as the sequence.

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.

Abstract: An access node (20) of a cellular network receives an information centric networking request of a user equipment (10) for a data object. The access node forwards the information centric networking request to a local gateway (30) associated with the access node (20). The local gateway (30) maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (30). In response to the user equipment (10) moving from a coverage area of the access node (20) to a coverage area of a further access node (21), the access node (20) and the further access node (21) perform a handover procedure. The further access node (21) is associated with a further local gateway (31) maintaining a further pending interest table. The further pending interest table includes an entry for each data object having a pending information centric networking request at the further local gateway (31).

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.
