Abstract: An electronic device that transmits a frame to a second electronic device is described. In particular, during operation, an interface circuit in the electronic device (such as an access point in a WLAN) may transmit the frame to the second electronic device using a Wi-Fi communication protocol. The frame may include information cancelling a previously specified NAV protected time in a preamble of the frame. For example, the information may include a CF-End indication. Moreover, the information may be included in a MAC header of the frame and, more generally, in a preamble of a high efficiency (HE) physical layer convergence protocol (PLCP) protocol data unit (PPDU). Furthermore, the electronic device may transmit the frame in response to a block acknowledgment (BA) from the second electronic device.

Abstract: A method, apparatus and system for transmitting control plane messages in a communication network. Messaging is between two logical nodes, e.g. gNBs. Logical nodes include multiple networked sub-entities. Multiple sub-interfaces couple a pair of logical nodes. One sub-interface is selected based on keys associated with content of a message. Key-to-sub-interface associations are stored in memory. The keys may be identifiers included in the control plane message, such as UE IDs, Cell IDs, etc. Packets carrying the control plane message are configured and transmitted using the selected sub-interface. A key-to-sub-interface association may be established or updated when a control plane message is received via the sub-interface and includes the key, or in response to a rejection message specifying the correct sub-interface to use. A middle box entity may be provided in a logical node for each sub-interface and configured to act at least initially to forward messages to appropriate sub-entities.
Abstract: Systems and methods are disclosed herein for updating stored User Equipment (UE) context information upon re-suspend of the UE in response to a resume request from the UE.

The method further comprises, in response to receiving the RRC connection release message with an indication for suspend, replacing information in a stored Access Stratum (AS) context of the UE with new information.
Abstract: Methods and systems for detecting an application associated with a given IP flow and differentially forwarding packets based on determined application are provided. According to one embodiment, an initial Internet Protocol (IP) packet of an IP flow is received by a network device. An application with which the initial IP packet is associated is determined by the network device. Based on the determined application, a forwarding rule to be applied to the initial IP packet is identified by the network device. Thereafter, the initial IP packet and subsequent IP packets associated with the IP flow are forwarded by the network device based on the identified forwarding rule.
