23、 (01/2009) 1 Recommendation ITU-T D.93 Charging and accounting in the international land mobile telephone service (provided via cellular radio systems) 1 General considerations 1.1 In the land mobile telephony service, the Home Public Land Mobile Network (HPLMN) will know the location of all operati
24、onal mobile stations for which it is the home registered network, when the station is operating within its HPLMN or has roamed in accordance with the principles contained in ITU-T Recommendations of the Q.1000 series. 1.2 The Visited Public Land Mobile Network (VPLMN) will be able to access and reco
25、rd the necessary details of any mobile station which has roamed and registered with it, such that it can forward all necessary billing information to the HPLMN. 1.3 Mobile stations will only be able to roam to another Public Land Mobile Network (PLMN): upon the conclusion of a bilateral agreement be
26、tween PLMNs; upon the granting by the HPLMN of the option to roam to the mobile station. 1.4 As part of the bilateral agreement, the HPLMN should undertake to pay the VPLMN the charges incurred by the HPLMN registered mobile subscribers. 1.5 Examples of the application of the charging and accounting
27、 principles, set out below, for various call routing scenarios are given in Annex A. 1.6 Definitions 1.6.1 home PLMN The PLMN in which a mobile station is permanently registered. 1.6.2 home location register The location register to which a mobile station is assigned for record purposes such as subs
28、criber information 1.6.3 visited PLMN The PLMN, other than the home PLMN, in which a roaming subscriber is currently located. 1.6.4 visitor location register The location register, other than the home location register used by an MSC to retrieve information for, for instance, handling of calls to or
29、 from a roaming mobile station, currently located in its area. 1.6.5 mobile station roaming number The network internal number used for routing of calls to the mobile station. See Recommendation ITU-T E.213. 2 Principles for charging 2.1 The charge structure and level in any country is a national ma
30、tter. 2.2 HPLMN charging 2.2.1 The HPLMN is responsible for billing the mobile subscriber for all incurred charges. 2.2.2 Charging structures should be as simple as possible. 2 Rec. ITU-T D.93 (01/2009) 2.2.3 The charge would normally consist of two components: a network access component; a network
31、utilization component. 2.2.3.1 The network access component is intended to cover the cost of making the service available, such costs being independent of network utilization: initial registration charge (non-recurring); subscription or rental (periodic). The network access component shall not be in
32、cluded in the international accounts. 2.2.3.2 The network utilization component is intended to cover the costs of the service which are dependent on network utilization: utilization charges (covering mobile, national/international elements as applicable); any supplementary service charges. 2.2.4 The
33、 charges billed to the mobile subscriber should be such as to cover the payments due to the VPLMN plus any handling charges which may also be raised. 2.3 VPLMN charging The charges raised by a VPLMN against the HPLMN should normally include one or more of the following: roaming registration fee (non
34、-recurring); roaming subscription (periodic); utilization charges (covering mobile, national/international elements as applicable); any supplementary service charges. 2.4 Fixed station charges In the case of a fixed station to mobile station international call, the charge to the calling station shou
35、ld be: a) the appropriate fixed station to fixed station charge; or b) where 3.3 b) below applies, a separately established charge to reflect the different cost associated with call delivery may be applied. 2.5 Mobile station-to-mobile station charges In the case of a mobile station-to-mobile statio
36、n international call, the charge to the calling station should be: a) the appropriate mobile station-to-fixed station charge; or b) where 3.3 b) below applies, a separately established charge to reflect the different costs associated with call delivery may be applied. 3 Principles for accounting 3.1
37、 International traffic originating or terminating at a mobile station will always be routed via the fixed networks of the countries concerned. The Administration of the country where the call originates should, therefore, include all such traffic in its regular international traffic accounts. 3.2 Th
38、e accounting rates for international traffic originating or terminating at a mobile station should be cost-orientated and should be applied on a non-discriminatory basis to all relations, taking into account the principles embedded in Rec. ITU-T D.140. Rec. ITU-T D.93 (01/2009) 3 3.3 International t
39、raffic terminating at a mobile network will be accounted for either: a) at the normal IDD rate for the relation concerned1; or b) in relationships where cost-orientated rates have been agreed, and where costs for terminating at a mobile network differ from those of terminating at a fixed network, a
40、separate rate may be bilaterally agreed for traffic terminating at a mobile network. In each case, both the rates for fixed and mobile traffic need to be cost-orientated based on the costs of terminating that traffic. The difference between the two rates should be as small as possible. 3.4 In a case
41、 where 3.3 b) is applied, suitable means need to be established by bilateral agreement to enable the Administration of origin to separately identify this traffic, for both charging and accounting purposes. 3.5 Where 3.3 b) applies, subject to bilateral agreement, the mobile terminating traffic will
42、have to be separately identified in the traffic accounts. 3.6 Where 3.3 b) would be applicable but traffic terminating at mobile network is more or less in balance in both directions of the relationship and costs are similar, the Administrations concerned may agree not to account separately for this
43、 traffic while it remains more or less in balance. 3.7 Where 3.3 b) applies but the difference between the two rates cannot objectively be justified on the basis of costs, the following could be considered: a) the difference between the rates for calls terminating on fixed networks on the one hand,
44、and calls terminating on mobile networks on the other (arrived at by deducting the lower from the higher), should be no greater than the corresponding difference between the average of the available interoperator rates for national fixed-to-fixed calls on the one hand, and the average of available i
45、nteroperator rates for all national calls terminating on a mobile network on the other. If such a comparison is not possible, the difference should be no greater than the corresponding difference between the average of retail rates for a national fixed-to-fixed call on the one hand, and the average
46、of retail rates for a national fixed-to-mobile call on the other hand. 4 Principles for settlements between PLMNs 4.1 The VPLMN should prepare a statement of the charges payable by the HPLMN for its registered mobile subscribers. The format and frequency of dispatch should be agreed between the two
47、parties. This statement should show the total charge expressed in SDRs or another agreed accounting currency, together with the conversion rate. 4.2 To ensure that the HPLMN has sufficient information for billing purposes, individual statements should be prepared for each registered subscriber. Thes
48、e statements should include the following information: a) The period covered by the statement. b) The subscriber identity in the HPLMN. c) For each call: i) the date and start time; ii) number called and area code; iii) destination country; _ 1In this case, the rate should be cost-orientated based o
49、n blended cost between the cost terminating at the fixed station and the mobile station. 4 Rec. ITU-T D.93 (01/2009) iv) duration in minutes and seconds; v) any supplementary services used. 4.3 In the absence of alternative settlement procedures agreed between the PLMNs concerned, settlement of balances shall be effected in accordance with the provisions of the Administrative Regulations 1. 5 Mobile Station Roaming Numbers (MSRNs) VPLMN should assign MSRN(s) from the E.164 resource of the actual
