5.6.3.7  Core Network Node - Core Network NodeWord‑p. 68
Reproduction of 3GPP TS 23.060, Figure 13: Control Plane for GTP-based Interfaces between Core Network Nodes
Up
Legend:
  • GPRS Tunnelling Protocol for the control plane (GTP-C): This protocol tunnels signalling messages between SGSNs and GGSNs (Gn or Gp), between SGSNs and S-GWs (S4), between S-GWs and P-GWs (S5 or S8) and between SGSNs in the backbone network (Gn or S16).
  • User Datagram Protocol (UDP): This protocol transfers signalling messages between GSNs. UDP is defined in RFC 768 [39].

5.6.3.8  GGSN - HLR

This optional signalling path allows a GGSN to exchange signalling information with an HLR. There are two alternative ways to implement this signalling path:
  • If an SS7 interface is installed in the GGSN, the MAP protocol can be used between the GGSN and an HLR.
  • If an SS7 interface is not installed in the GGSN, any GSN with an SS7 interface installed in the same PLMN as the GGSN can be used as a GTP-to-MAP protocol converter to allow signalling between the GGSN and an HLR.

5.6.3.8.1  MAP-based GGSN - HLR Signalling
Reproduction of 3GPP TS 23.060, Figure 14: Control Plane GGSN - HLR Using MAP
Up
Legend:
  • Mobile Application Part (MAP): This protocol supports signalling exchange with the HLR, as described in clause "Network-Requested PDP Context Activation Procedure".
5.6.3.8.2  GTP and MAP-based GGSN - HLR SignallingWord‑p. 69
Reproduction of 3GPP TS 23.060, Figure 15: Control Plane GGSN - HLR Using GTP and MAP
Up
Legend:
  • GPRS Tunnelling Protocol for the control plane (GTP-C): This protocol tunnels signalling messages between the GGSN and the protocol-converting GSN in the backbone network.
  • Interworking: This function provides interworking between GTP and MAP for GGSN HLR signalling.

5.6.3.9  S4-SGSN - HSS |R8|

Reproduction of 3GPP TS 23.060, Figure 15a: Control Plane S4-SGSN - HSS
Up
Legend:
  • Diameter Base+Apps: Diameter Base Protocol as defined in RFC 3588 [96]. The Apps are various Diameter Applications as necessary for the operation between SGSN and HSS.
  • SCTP: This protocol guarantees delivery of upper layer packets between SGSN and the HSS with built-in redundancy scheme. SCTP is defined in RFC 4960 [35].

5.6.3.10  Gn/Gp-SGSN - CSS |R11|Word‑p. 70
Reproduction of 3GPP TS 23.060, Figure 5.6.3.10-1: Control Plane Gn/Gp-SGSN CSS
Up
Legend:
  • Mobile Application Part (MAP): This protocol supports signalling between Gn/Gp-SGSN and CSS, as defined in clause "Mobility Management Functionality".

5.6.3.11  S4-SGSN - CSS |R11|

Reproduction of 3GPP TS 23.060, Figure 5.6.3.11-1: Control Plane S4-SGSN-CSS
Up
Legend:
  • Diameter: This protocol supports signalling messages between S4-SGSN and CSS (S7d), as described in clause "Mobility Management Functionality". Diameter is defined in RFC 3588 [96].
  • Stream Control Transmission Protocol (SCTP): This protocol transfers signalling messages. SCTP is defined in RFC 4960 [35].

5.6.3.12  SGSN - RCAF (Iu mode) |R13|Word‑p. 71
Reproduction of 3GPP TS 23.060, Figure 5.6.3.12-1: Control Plane SGSN-RCAF
Up
Legend:
  • Nq-AP: This application layer protocol supports the APN information retrieval procedure between the RCAF and the SGSN.
  • Stream Control Transmission Protocol (SCTP): This protocol transfers signalling messages. SCTP is defined in RFC 4960 [35].
Editor's note: The protocol stack will be added once Stage 3 has selected the protocol type to use between S4-SGSN and RCAF. It is up to Stage 3 to decide whether the same or different protocols will be used for the Nq' interface to the Gn/Gp-SGSN and the S4-SGSN, respectively.
