  1. Proposal for registration of A-MG via AGCF Version：V1.0 Reporter：Yan Hong Date：2014年9月6日

  2. Table of Contents • Introduction about AGCF • Registration process

  3. Introduction about AGCF TISPAN PSTN/ISDN Emulation Subsystem - Functional Architecture

  4. Introduction about AGCF • AGCF is specific to the PSTN/ISDN emulation subsystem. It’s the first point of contact for residential and access media gateways. • AGCF is acting as an MGC for controlling media gateways functions (R-MGF and A-MGF) located in residential and access gateways .

  5. Purpose of the proposal • AGCF performs signalling interworking between SIP and analog signal via the P1 reference point. When the protocol running on P1 reference point is H.248，the protocol doesn’t define registration for user. The document is trying to provide a practical method for registration of A-MG. • The following will represent a method “domain registration”

  6. Registration process PES APP UPSF Cx ISC AGCF S-CSCF Mw P1 P1：H.248 Mw:：SIP A-MG

  7. Registration process • Domain registration: • A-MGAGCF: When A-MG start/restart, A-MG sends ServiceChange to AGCF; • AGCFS-CSCF: AGCF sends SIP-register to S-CSCF with IP address of A-MG. All the subscribers in A-MG are registered by this operation. • S-CSCFUPSF:S-CSCF register the domain of A-MG to UPSF. UPSF will record the related S-CSCF of the A-MG domain.

  8. Registration process When storing a new subscriber in HSS, get the related S-CSCF same as the domain’s.
