SCOPE Since a homogeneous, compatible service spectrum is the objective for the services of GSM PLMNs, standardization of the charging mechanisms for collection char
8、ges is the minimum requirement. This is especially important as mobile subscribers can move in different GSM PLMNs. It is therefore the objective of this recommendation to standardize at least those charging mechanisms which play a role in the technical definition of GSM PLMNs . The recommendation d
9、eals with the charging mechanisms related to GSM mobile originated calls and with the forwarded element of GSM mobile terminated call (i.e. when the GSM mobile subscriber is roaming), hereafter referred to as “the mobile terminated component “ . The Transferred Account Procedure is dealt with in Rec
10、ommendation GSM 02.21 and the implementation aspect of the supplementary service “Advice of charge“ is described in GSM 02.24. 1. TARIFF STRUCTURE 1.1. General The tariff for the service should normally consist of two components: - a network access component - a network utilization component The net
11、work access component, normally intended to cover the cost of making the service available, represents the cost of the service which is not dependent on network utilization. It corresponds to what is generally known as the “network connection charges“. The network utilization component normally cove
12、rs the costs which are dependent on network utilization. 1.2. Network access component Access charges should be levied for each subscription (see GSM Rec. 02.13). They may consist of: a) an initial fee (non-recurring) b) a subscription charge (payable at certain intervals, e.g. monthly or quarterly,
13、 until the subscription is terminated) The access charges may vary according to: a) the entitlement of the subscription (see GSM Rec. 02.13) b) the number of basic and supplementary telecommunication services subscribed to m 3404583 0069726 982 m GSM 02.20 - version 3.0.1 - 3 1.3. Network utilizatio
14、n component The network utilization component is registered on a per call basis. The basic working assumption is start of charging by B- answer (forwarded-to-subscriber on call forwarding) or on connection to recorded message systems internal to the network if prescribed by national requirements. (T
15、echnical note: Charging starts on the answer message in signalling system no. 7.) The main elements are: - use of GSM PLMNs (radio path, base station equipment, lines - use of national/international fixed networks - use of connection between the different networks - use of signalling system No. 7 BS
16、S-MSC, MSC) The network utilization charge may vary according to: a) from which country and/or regional area (see Rec. GSM b) the destination (called party) c) day and time when the call is established d) registration, erasure, activation, deactivation, interrogation and invocation of supplementary
17、services e) the location of the called party (roaming mobile subscriber) f) the telecommunication service used. 02.13) the call is originated 2. HANDLING OF THE COLLECTION CHARGES 2.1. Network access charae The network access charge will normally be based on data registered in the subscription handl
18、ing procedures. The access charges shall not be included in accounts between network operators, and their establishment is strictly a national/network matter. The network access charges are collected by the HPLMN operator from his subscribers. 2.2. Network utilization charqes 2.2.1. Mobile originate
19、d calls The network utilization charges for mobile originated calls may vary according to the items mentioned in section 1.3. The charging analysis can be done in the originating network, based on analysis of the called number. m 3404583 00b9727 819 m GSM 02.20 - version 3.0.1 - 4 t b The charging a
20、spects of the bearer service supporting PAD access however, in respect of volume charges, is for further study. 2.2.2. Mobile terminated calls For mobile terminated calls, the called mobile subscriber - hereafter called the B-subscriber - may be charged for the mobile terminated component when roami
21、ng. The mobile terminated component may vary according to the actual location of the B- subscriber. The possible routings of roaming mobile terminated calls are shown in the figures below. Figures 1, 2 and 3 shows the routings of calls to national mobile subscribers, roaming both nationally and inte
22、rnationally. Figures 4, 5, 6, 7 and 8 shows the routing possibilites of calls made to foreign mobile subscribers. 2.2.2.1 . Use of “Call forwarding“ supplementary services - When one of the “Call forwarding“ supplementary services is activated and the call is forwarded to a subscriber in the fixed n
23、etwork - hereafter called the C-subscriber - the same mobile terminated component as described in section 2.2.2 may be charged the B-subscriber. calls forwarded to the fixed network In addition the B-subscriber may be charged for the forwarded part of the call, i.e. from the MSC where the B-subscrib
24、er is actually located, to the network of the C-subscriber, see Figure 9. Exception is made for “Call forwarding unconditional“ when routing is made directly to the C-subscriber, based on information from the HLR. The B-subscriber may in this case be charged for the forwarded part of the call as sho
25、wn in Figure 10. 2.2.2.2. Use of “Call forwardinq“ supplementary services - calls forwarded to a GSM PLMN When one of the “Call forwarding“ supplementary services is activated, and the call is forwarded to another GSM Mobile Subscriber, the B-subscriber may be charged for both the mobile terminated
26、component and the forwarded part of the call, as described in section 2.2.2.1. In addition the C-subscriber, when roaming, may be charged for the mobile terminated component, see Figures 11 and 12. GSM 02.20 - version 3.0.1 - 5 2.2.3. Collection of the network utilization charges The network utiliza
27、tion charges for calls originated by GSM mobile subscribers roaming between GSM PLMNs, and the mobile terminated component shall be transferred to the HPLMN operator (see GSM Rec. 02.21). The level of the network utilization charge collected from the subscriber is a national matter, and may therefor
28、e vary. The network utilization charges registered in HPLMN and VPLMNs (including the mobile terminated component and the forwarded part of the calls) are collected by the HPLMN operator from his subscribers. The network utilization charges for GSM mobile terminated calls, except for the mobile term
29、inated component and the forwarded part of the calls, are collected from the calling subscriber.
