5  Functional Description and Procedures for 3GPP Accesses with PMIP-based S5/S8  p. 84

5.1  Control and User Plane Protocol Stacks  p. 84

5.1.1  Void

5.1.2  General  p. 84

TS 23.401 defines the protocol stack for both the control plane and user plane for 3GPP accesses using GTP-based S5/S8. This clause defines the protocol stacks for 3GPP accesses using the PMIP-based S5/S8.

5.1.3  Control Plane  p. 85

5.1.3.1  Serving-GW - PDN-GW  p. 85

Legend:
  • The control part of PMIPv6 specification, RFC 5213) protocol is used for signalling messages between Serving-GW and PDN-GW (S5 or S8).

5.1.4  User Plane  p. 85

5.1.4.1  UE - PDN-GW User Plane with E-UTRAN  p. 85

Legend:
  • On the S5/S8 interface, the tunnelling layer implements GRE encapsulation applicable for PMIPv6.
  • MME controls the user plane tunnel establishment and establishes User Plane Bearers between eNodeB and Serving-GW.
  • EUTRAN-Uu: The radio protocols of E-UTRAN between the UE and the eNodeB are specified in TS 36.300.
  • IP: This refers to network layer protocols. On the Serving Gateway this includes termination of the UE-Serving Gateway link-local protocols (e.g. IPv6 Router Solicitation/Advertisement) and forwarding of user plane IP packets between the UE-SGW point-to-point logical link and the S5/S8 tunnel for the UE.

Legend:
  • On the S5/S8 interface, the tunnelling layer implements GRE encapsulation applicable for PMIPv6.
  • Protocols on the Um and the Gb interfaces are described in the TS 23.060.
  • IP: This refers to network layer protocols. On the Serving Gateway this includes termination of the UE-Serving Gateway link-local protocols (e.g. Router Solicitation/Advertisement) and forwarding of user plane IP packets between the UE-SGW point-to-point logical link and the S5/S8 tunnel for the UE.
