ISO IEC 15430:1999 pdf download – lnformation technology – Telecommunications and informationexchange between systems- Privatelntegrated Services Network — Specification, functional model and information flows-Wireless terminal call handling additional network features.
Additional network feature Wireless ternnal incoming call (ANF-WTMI) directs inoornmg calls to a WTMI user within a PISN regardless of the WTMI users geographical location within the PISN, provided the WTMI use(s location is known.
Additional network feature Wireless terminal oulgoing call (ANF-WTMO) detects an outgoing call from a WTMO user and establishes it as a basic call. regarc$ess of the user’s geographical location within the PISN, It also provides the WTMO users service profile for use by outgoing call control, or alternatively passes the call to the WTMO user’s home location tar processing.
Service specifications are produced in three stages, accorng to the method described in CCITT Recommendation 1.130. This International Standard contains the stage I and stage 2 specifications of ANF-WTMI and ANF-WTMO. The stage 1 specification (clauses 6 and 7) specifies the service as seen by users of PISNs. The stage 2 specification (clauses 8 and 9) identities the functional entitles Involved In the service and the Information flows between them.
2 Conformance
In order to conform to this International Standard, a stage 3 International Standard shall specify signalling protocols and equipment behaviour that are capable ol being used In a PISN which supports the services specified In this International Standard. This means that, to claim conlormance. a stage 3 International Standard ts required to be adequate for the support of those aspects 04 clauses 6 and 7 (stage 1) and clauses 8 and 9 (stage 2) which are relevant to the interface or equipment to which the stage 3 International Standard applies.

ANF-WTMI shall be permanently activated.
Registration and interrogation are not applicable to this ANF.
6.22.2 Invocation and operation
For each WTMI user, information shall be maintained relating to the location of the WTMI user within the PISN.
ANF-WTMI shall be invoked for an incoming call when analysis of me destination number indicates that the called user is a WTMI user. Once invoked. ANFWTMI shall route the call to the WTMI user using the destination number to determine the address of the PISN access currently in use by the WTMI user.
Further processing of the call shall follow normal basic call procedures.

It the PISN is unable to complete an incoming call to a WTMI user, an indication that the call was unsuccessful shall be sent to the calling user. Normal basic call failure procedures shall be used.
