ISO IEC 17878-2003 pdf – Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Private User Mobility (PUM) — Call handling additional network features
1 Scope This International Standard specifies the signalling protocol for the support of the Private User Mobility call handling additional network features (ANF-PUMI and ANF-PUMO) at the Q reference point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN). ANF-PUMI is a feature that directs incoming calls to a PUM user within the PISN regardless of the PUM user’s geographical location 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. This International Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the 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 switched call control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference 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. 2 Conformance In order to conform to this International Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation Conformance Statement (PICS) proforma in annex A.

6 Signalling protocol for the support of ANF-PUMI 6.1 ANF-PUMI description ANF-PUMI enables calls to be directed to a PUM user within the PISN. As there is no predetermined PINX for the connection of a PUM user to the PISN, the directing of such calls requires that information regarding the location of the user is available. 6.2 ANF-PUMI operational requirements 6.2.1 Requirements on the Rerouteing PINX ISO/IEC 11572 protocol control procedures for call establishment at the outgoing side of an inter-PINX link shall apply to the establishment of the connection to the Visitor PINX. ISO/IEC 11572 protocol control procedures for call clearing shall apply to the release of the connection to the PUMI-detect PINX. Generic procedures for the call related control of supplementary services, as specified in ISO/IEC 11582 for an End PINX, shall apply. 6.2.2 Requirements on the PUMI-detect PINX ISO/IEC 11572 protocol control procedures for call establishment at the incoming side of an inter-PINX link shall apply to the establishment of the connection from the Originating or Incoming Gateway PINX. ISO/IEC 11572 protocol control procedures for call clearing shall apply to the release of the connection to the Rerouteing PINX. Generic procedures for the call related control of supplementary services, as specified in ISO/IEC 11582 for an End PINX, shall apply. Generic procedures for the call independent control (connection oriented) of supplementary services, as specified in ISO/IEC 11582 for an Originating PINX, shall apply. 6.2.3 Requirements on the Home PINX Generic procedures for the call independent control (connection oriented) of supplementary services, as specified in ISO/IEC 11582 for a Terminating PINX, shall apply.
