ISO IEC 17876-2003 pdf – Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Private User Mobility (PUM) — Registration supplementary service.
1 Scope This International Standard specifies the signalling protocol for the support of the Private User Mobility Registration supplementary service (SS-PUMR) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). SS-PUMR is a supplementary service which enables a PUM user to register at, or de-register from, any wired or wireless terminal within the PISN. The ability to register at different locations in the PISN at different times enables the PUM user to maintain the provided services (including the ability to make and receive calls) at different access points. De-registration is used to inform the PISN that the PUM user is temporarily unable to make use of the provided services (including the receipt of calls). SS-PUMR may provide the PUM user with the ability to obtain information on the current registration sessions (interrogation). 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 17875. The signalling protocol for SS-PUMR 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 SS-PUMR and other supplementary services and ANFs. NOTE 1 – Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in the relevant stage 1 specifications. This International Standard is applicable to PINXs which can interconnect to form a PISN. This International Standard applies to PUM only within a single PISN. 2 Conformance In order to conform to this International Standard
4.2 Remote PINX Any PINX in the private network not coincident with the Visitor PINX, from which a PUM user or another authorized user has access to the features (registration/de-registration and interrogation) of SS-PUMR. 4.3 Previous Visitor PINX A PINX in the private network, at which a PUM user is still registered and has to be de-registered from when he attempts to register at another Visitor PINX. 4.4 Alternative identifier An identifier, other than the PISN number, which identifies the PUM user uniquely. 4.5 Activating user Either the PUM user himself or an authorized user acting on behalf of the PUM user. 5 List of acronyms ANF Additional Network Feature APDU Application Protocol Data Unit ASN.1 Abstract Syntax Notation no.1 CT Call Transfer HDB Home Data Base ISDN Integrated Services Digital Network MWI Message Waiting Indication NFE Network Facility Extension PICS Protocol Implementation Conformance Statement PINX Private Integrated services Network eXchange PISN Private Integrated Services Network PUM Private User Mobility SDL Specification and Description Language
6 Signalling protocol for the support of SS-PUMR 6.1 SS-PUMR description SS-PUMR is a supplementary service which enables a PUM user to register at, or de-register from, any wired or wireless terminal within the PISN. The ability to register for incoming calls (InCall registration) is mandatory, whereas the ability to register for outgoing calls (OutCall registration) or for both incoming and outgoing calls (AllCall registration) is optional. The ability to register at different locations in the PISN at different times enables the PUM user to maintain the provided services (including the ability to make and receive calls) at different access points. De-registration is used to inform the PISN that the PUM user is temporarily unable to make use of the provided services (including the receipt of calls). SS-PUMR may provide the PUM user with the ability to obtain information on the current registration sessions (interrogation). 6.2 SS-PUMR operational requirements 6.2.1 Requirements on the Visitor PINX Generic procedures for the call independent control (connection oriented) of supplementary services, as specified in ISO/IEC 11582 for an Originating and Terminating PINX, shall apply. 6.2.2 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 and an Originating PINX, shall apply. 6.2.3 Requirements on the Previous Visitor 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. 6.2.4 Requirements on a Transit PINX Generic procedures for the call independent control (connection oriented) of supplementary services, as specified in ISO/IEC 11582 for a Transit PINX, shall apply. 6.2.5 Requirements on the Directory 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.
