ISO IEC 17877 pdf download – Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Specification, functional model and information flows — Private User Mobility (PUM) — Call handling additional network features
scope
This International Standard specifies the Additional Network Features (ANF) Private User Mobility Incoming Call (PUMID)and Private User Mobility Outgoing Call (PUMO), which are applicable to various basic services supported by PrivateIntegrated Services Networks (PISN).Basic services are specified in iSo/EC 11574.
ANF-PUMl is an additional network feature that directs incoming calls to a PUM user within a PISN regardless of the PUMuser’s geographical location within the PISN, provided the PUM user’s location is known.
ANF-PUMO is an additional network feature that permits the PISN to process call requests from a PUM user at the homelocation, if required.
Additional network feature specifications are produced in three stages, according to the method described in ETS 300 387.This International Standard contains the stage 1 and stage 2 specifications of ANF-PUMI and ANF-PUMO. The stage lspecification(clauses 6 and 7) specifies the general feature principles and capabilies.The stage 2 specification (clauses 8 and9) identifies the Functional Entities involved in the additional network features and the information flows between them.
2Conformance
In order to conform to this International Standard,a stage 3 standard shall specify signalling protocols and equipmentbehaviour that are capable of being used in a PISN which supports the additional network features specified in thisInternational Standard.This means that, to claim conformance, a stage 3 standard is required to be adequate for the support ofthose aspects of clauses 6 and 7 (stage l) and clauses 8 and 9 (stage 2) which are relevant to the interface or equipment towhich the stage 3 standard applies.
