name: PMIPv6
full_form: Proxy Mobile IPv6
context: SGi PtP tunnelling mechanisms such as PMIPv6/GRE, L2TP, GTP-C/U, etc, may be used to deliver Non-IP data to AS via SGi.
  The PtP tunnel is established towards the AS by the P-GW. Depending on the type of protocol employed on the SGi PtP tunnel, the SGi PtP tunnel setup may be done at the time of attach or at the time of first MO datagram being sent by the CIoT UE.
  The P-GW selects the AS based on the P-GW configuration (eg. per APN, or per PtP tunnel type etc).
  NOTE:	IP address allocation procedures for the UE are not performed by the P-GW.
  For uplink Non-IP data, the P-GW forwards the received data to the AS over the established SGi PtP tunnel.
  For downlink Non-IP data, the AS locates the right SGi PtP tunnel for the UE (using information such as UE identifiers in the Non-IP protocol itself, etc) to forward the data. The AS sends the data to P-GW over the established SGi PtP tunnel. The P-GW inturn sends the data to S-GW on the GTP-U tunnel identified by the associated SGi PtP tunnel for delivery to the UE.
description: PMIPv6 is a protocol used for mobility management in mobile networks, enabling the delivery of Non-IP data to AS via SGi PtP tunneling mechanisms.
explanation: Categorized as a Protocol because it manages mobility and session control between network components.
