eBCS AP Tagged UL Forwarding Use Case

This use case scenario involves pre-configured low-cost tracker devices connecting to a server through eBCS APs with appended metadata for secure forwarding, benefiting IoT users and operators. It enhances broadcast capability and reduces implementation complexity.

  1. Use Case Document: AP tagged UL forwarding • Date: 2019-05-14 Authors: Abhishek Patil (Qualcomm)

  2. Abhishek Patil (Qualcomm) Abstract This presentation provides an additional use case scenario to be incorporated into TGbc use case document (11-19/0268) and updating the TGbc Functional Requirements document (11-19/0151).

  3. Abhishek Patil (Qualcomm) Stakeholders IoT Users, IoT operators, tracking services, etc Manufactures of semiconductor, APs, networking and mobile devices Use Case xx: AP tagged UL forwarding Topology/Architecture • Required function • Pre-configured low-cost low power tracker device automatically connects to an end server through eBCS APs in the neighborhood with zero setup action • Tracker device periodically reports to its server through eBCS APs without scanning and association • eBCS AP appends metadata (such as IP, date/time, location, RSSI etc) to the packets before forwarding to the destination server • Meta-data from an eBCS AP will be protected • Service scene • An eBCS AP provides forwarding service to an end-servers for eBCS non-AP STAs that may not be associated with the AP • An eBCS AP appends on additional information before forwarding the packet to the addressed server • Expected Benefits: • Ability to broadcast information destined to the end server • Ability to reduce cost and implementation complexity • Ability to enable low power STA operations

  4. Additions to Functional Requirements document • 3.4 Association state • TGbc R6: The 802.11bc amendment shall support modes of operation: • a) in an infrastructure BSS where there is an association between the transmitter and the receiver(s) • b) in cases where there is no association between transmitter(s) and receiver(s). [Ref-1 5.2.b] • TGbc R7: 802.11bc amendment shall have a mechanism to facilitate power-efficient broadcasting. • TGbc R8: 802.11bc amendment assumes that there is no association and/or handshake required between STA and the AP. • TGbc Rx: 802.11bc amendment shall provide a mechanism for an AP to append metadata (such as IP address, date, time, location, RSSI) to a packet before forwarding it to a remote server • 3.3 Security • TGbc R3: The 802.11bc amendment shall provide origin authenticity protection for broadcast data frames. [Ref-1 5.2.b] • TGbc R4: The 802.11bc amendment shall provide a broadcast mechanism in which e2e security w/ confidentiality and integrity between STA and the server is assumed. • TGbc R5: The 802.11bc amendment shall provide a mechanism for the AP to verify the STA before forwarding the packets. • TGbc Rx: The 802.11bc amendment shall provide a mechanism in which e2e security w/ confidentiality and integrity between AP and the remote server is achieved Abhishek Patil (Qualcomm)
