31、0 Release 141 Scope The present document specifies the technical realisation of the first phase of the network feature Support of Optimal Routeing (SOR). The first phase of SOR provides: - as a network operator option, a method to route a call from one mobile subscriber directly to another mobile su
32、bscriber who is in the same country as the calling mobile subscriber or in the called mobile subscribers home country, without needing to connect the call via the HPLMN of the called subscriber, even though the called mobile subscriber has roamed outside his HPLMN; - a method to forward calls when a
33、 called mobile subscriber who has roamed outside his home country is busy, or is not reachable, or does not reply, to a forwarded-to destination in the HPLMN country of the called subscriber or the VPLMN country of the called subscriber, without needing to connect the forwarded call via the VPLMN of
34、 the called subscriber; - a method to combine the optimal routeing described in the first bullet point above with the optimal routeing described in the second bullet point above. OR of a call is permitted only if all entities involved in handling the call support OR. Other cases of optimal routeing
35、(e.g. calls where the calling and called subscribers are in different countries, forwarding to a mobile subscriber or multiple forwarding) will be considered for inclusion in later phases. 2 References The following documents contain provisions which, through reference in this text, constitute provi

A subsc
41、riber: calling subscriber, who may be fixed or mobile B subscriber: mobile subscriber originally called by the A subscriber C subscriber: subscriber to whom the B subscriber has requested that calls be forwarded. The C subscriber may be fixed or mobile Direct route: call takes the direct route if th
42、e route from the serving PLMN of the A subscriber to the serving PLMN of the B subscriber is defined by the MSRN of the B subscriber rather than by the MSISDN of the B subscriber Early call forwarding: call forwarding from the IPLMN before the call has been extended to the VPLMN of the forwarding su
43、bscriber HPLMN leg: portion of the HPLMN route from the serving MSC of the A subscriber to an MSC in the HPLMN of the B subscriber HPLMN route: call takes the HPLMN route if the route from the serving MSC of the A subscriber to the serving MSC of the B subscriber is defined by the MSISDN of the call
44、ed subscriber. This forces the call to be routed via the HPLMN of the B subscriber Interrogating PLMN (IPLMN): PLMN which interrogates the HPLMN of the B subscriber to obtain information to route the call to that subscriber or to the forwarded-to destination defined by the called mobile subscriber.
45、The IPLMN is also the VPLMN of the A subscriber Late call forwarding: call forwarding after the call has been extended to the VPLMN of the forwarding subscriber. Late call forwarding may be invoked in the IPLMN or the VPLMN of the forwarding subscriber Reference address: address which defines the ma
46、ximum charge which the A party is prepared to pay for the call leg which he originates Routeing address: address which the GMSC uses to route a call towards the B subscriber or the C subscriber ETSI ETSI TS 123 079 V14.0.0 (2017-04)83GPP TS 23.079 version 14.0.0 Release 143.2 Abbreviations Abbreviat
