1Scope
This International Standard specifies the signalling protocol for the support of the Private User Mobility call handligadditional network features (ANF-PUMI and ANF-PUMO) at the Q reference point between Private Integrated servicesNetwork eXchanges (PINX) connected together within a Private Integrated Services Network (PISN).
ANF-PUMl is a feature that directs incoming calls to a PUM user within the PISN regardless of the PUM user ‘s geographicallocation within the PISN, provided that the PUM user’s location is known.
ANF-PUMO permits the PISN to process call requests from a PUM user at the home location, if required.The Q reference point is defined in ISO/IEC 11579-1.
Service specifications are produced in three stages and according to the method specified in ITU-T Rec. I.130. Thislnternational Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified bythe stage 1 and stage 2 specifications in ISo/IEC 17877.
The signalling protocol for ANF-PUMI and ANF-PUMO operates on top of the signalling protocol for basic circuit switchedcall control, as specified in ISOIEC 11572, and uses certain aspects of the generic procedures for the control of supplementaryservices specified in ISO/IEC 11582.
This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Qreference point between ANF-PUMI /ANF-PUMO and other supplementary services and ANFs.
This International Standard is applicable to PINXs which can interconnect to form a PISN.
2Conformance
ln order to conform to this International Standard,a PINX shall satisfy the requirements identified in the ProtocolImplementation Conformance Statement (PICS) proforma in annex A.
