28、technical realisation of the first phase of the network feature Support of Optimal Routeing (SOR) within the 3GPP system. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present

29、 document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change

30、 control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document.

31、Release 131 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 subs

32、criber 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 c

33、alled 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 t

34、he 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 (e

35、.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 provisi

A subscriber: c

41、alling 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 the route

42、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 subscriber

43、 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 called subsc

44、riber. 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. The IPLM

45、N 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 maximum ch

46、arge 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 V13.0.0 (2016-01)83GPP TS 23.079 version 13.0.0 Release 133.2 Abbreviations Abbreviations use
