  • Publication number: 20240388962
    Abstract: A transmit network node (14, 20) is configured for use in a wireless communication network (10). The transmit network node (14, 20) tunnels packets (18) from the transmit network node (14, 20) to a receive network node (20, 14) in the wireless communication network (10). The transmit network node (14, 20) also transmits, to the receive network node (20, 14), signaling (26) that indicates which tunneled packets (18) carry application layer data from the same application layer packet (16), how many tunneled packets (18) carry application layer data from the same application layer packet (16), and/or a size of an application layer packet (16). Based on the signaling (26), the receive network node (20, 14) in some embodiments schedules transmission of the tunneled packets (18) from the receive network node (20, 14) and/or allocates radio resources for transmission of the tunneled packets (18) from the receive network node (20, 14) towards a wireless device (12) served by the receive network node (20, 14).

  • Patent number: 12114392
    Abstract: A wireless device, a network node, a core node and methods therein, for managing reachability of the wireless device. The wireless device starts an AS (Access Stratum) reachable timer when entering an inactive state. If the AS reachable timer expires while still in the inactive state, the wireless device sends to the network node a reachable notification indicating that the wireless device is reachable. If entering a connected state before the AS reachable timer expires, the wireless device stops the AS reachable timer when changing from the inactive state to a connected state. If the core node receives from the network node a not reachable notification indicating that the wireless device is not reachable, the wireless device can be marked as not reachable via paging.
