7 Reference points between the PLMN and other networks
7.1 Reference point fixed networks - MSC
7.2 Reference point GGSN - packet data networks (Gi reference point)
7.2a Reference point PDN GW - packet data networks (SGi reference point)
7.3 Reference point GMLC - external LCS Client (Le reference point)
7.4 Reference Point CSCF/IBCF - Multimedia IP networks (Mm Reference Point)

7.7 Reference Point WAG - WLAN access network (Wn reference point)
7.8 Reference point MTC-IWF - SCS (Tsp reference point)
7 Reference points between the PLMN and other networks p. 108
The reference points between the PLMN and other networks, including dedicated networks, are described in the 49-series of Technical Specifications and in the 29-series of Technical Specifications.
7.1 Reference point fixed networks - MSC p. 108
The MSC is based on a normal ISDN exchange. It has, for call control, the same reference points as the fixed network exchanges. The signalling reference point considered in the Technical Specifications is related to the signalling system No. 7 User Parts TUP and ISUP associated to the circuits used for incoming and outgoing calls.
7.2 Reference point GGSN - packet data networks (Gi reference point) p. 108
This is the reference point between the GGSN and a packet data network. It may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services.
7.2a Reference point PDN GW - packet data networks (SGi reference point) |R8| p. 108
This is the reference point between the PDN GW and a packet data network. It may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services. For more details see TS 29.061.
7.3 Reference point GMLC - external LCS Client (Le reference point) p. 108
At this reference point external LCS Clients request services from the PLMN.
7.4 Reference Point CSCF/IBCF - Multimedia IP networks (Mm Reference Point) |R5| p. 108
This is an IP interface between CSCF/IBCF and IP networks. This interface is used, for example, to receive a session request from another SIP server or terminal.
7.5 Void
7.6 Reference point PDG - packet data networks (Wi reference point) |R6| p. 108
This is the reference point between the PDG and a packet data network. It may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services.
7.7 Reference Point WAG - WLAN access network (Wn reference point) |R6| p. 109
This is the reference point between the WAG and the WLAN access network. It is used to force traffic between a WLAN UE and PDG to go through the WAG.
7.8 Reference point MTC-IWF - SCS (Tsp reference point) |R11| p. 109
See clause 6a.16.1.
This interface is an interface between the PLMN and other networks if the SCS is not controlled by the operator.
