ETSI 6 ETSI ES 201 296 VI .3.1 (2003-04) 1 Scope The present document specifies the stage three of the transfer of charging related information between a ch

21、arge determination point and a charge registration or charge generation point by means of the Signalling System N0.7 protocol. Additionally a connection control point may be located between determination point and a charge registration or charge generation point. Stage three identifies the protocol

22、procedures and switching functions needed to support a fe ature. The present document is applicable to an environment where different operators are working together. It is also applicable to a single network operator environment. Whether the present document is applicable to a national environment a

23、ndor can be used for inter-network purposes depends on regulatory demands andor bilateral agreements. It should be noted that there are network requirements and signalling limitations that are not covered because they are outside the scope of the present document. Examples of these are as follows: -

24、 which currency is used; - capabilities that require a translation function of currencies or for the translation of currencies into metering pulses; with an analogue access with pulse metering, no distinction can be made between pulses resulting from charges imposed by different operators; - - the o

25、n-line provided advice of charge information may not accurately reflect the correct charging rate due to discount rates, special charging arrangements, etc.; in association with these charging procedures, changes of the ISDN AOC supplementary services may be required for the identification of the ne

26、twork operator; new services like B-ISDN and new IN call concepts are not fully considered in the present document; especially the relay of charging information within configurations with more than one B subscriber at the same time (e.g. conference calls) is not supported; no interworking is covered

27、 with existing implementations making use of implicit information elements pointing to locally available charging data; complaint handling between network operators in case of incorrect advice of charge information; explicit encryption or special security mechanisms. - - - - - This application makes

28、 use of the Application Transport Mechanism (APM) described in 2. The present document specifies the respective user, i.e. the APM-user, to support the transfer of charging related information.

34、 and OA non-protocol functions, i.e. exchange nodal functions; this is referred to as the “Application Process“. The present document describes only the part of the total Application Process and protocol functions in the exchange that relates to the transfer of charging related information between a

35、 charge determination point and a charge registration or charge generation point. The protocol functions are subdivided into three parts: Charging ASE, Application Transport Mechanism (APM ASE) and ISUP Basic Call (ISUP ASE). These are Co-ordinated by the Single Association Control Function (SACF).

36、The ISUP ASE is defined in i. It is not the intention of the present document to re-define ISUP i in ALS format. The Application Transport Mechanism is specified in 2. The Charging ASE is a user of the services offered by the APM ASE. It is responsible for preparing the charging information in a for

37、m that can be transported by the Application Transport Mechanism. This separation of the procedural description provides a logical and convenient document structure but does not imply that the ISUP protocol itself is separated: e.g. in the context of the present document, the Initial Address message

38、 always signifies the simultaneous set-up of a bearer and an associated call. The service primitive technique, used to define the ASES and the SACF specific to the applications signalling needs, is a way of describing how the services offered by an ASE, or SACF - the provider of (a set) of service(s

39、) - can be accessed by the user of the service(s) - the SACF or the Application Process, respectively. The service primitive interface is a conceptual one and is not a testable or accessible interface. It is a descriptive tool. The use of service primitives at an interface does not imply any particu

40、lar implementation of that interface, nor does it imply that an implementation shall conform to that particular service primitive interface to provide the stated service. All conformance to the ISUP specifications is based on the external behaviour at a node, i.e. on the generation of the correct me

41、ssage structure (as specified in i), operation structure (as specified in the present document) and in the proper sequence (as specified in i and the present document). The interfaces between SACF and APM ASE, to ISUP basic call signalling ASE, between SACF and NI, and to MTP-3 are described in 2. E

42、TSI 10 ETSI ES 201 296 VI .3.1 (2003-04) 5 Description 5.1 Gen eral description The present document specifies the procedures for the transfer of charging related information between a charge determination point, a connection control point and a charge registration or charge generation point (see al

43、so annex B). A charge determination, connection control, charge registration and charge generation point of the call may be located within the network of one operator (single network operator environment) or may be located in different networks of different operators (multi-operator environment). Th

44、e configuration of several charge determination points for one call is possible. It is assumed that there is only one CGP for the call. Moreover, it is assumed for the present document that there is either one CRP for each CDP or one CRP for all CDPs. The transferred tariff information represents di

45、rect tariff or add-on charge (no pointers to charging data), either in meter-pulse format or in currency format. The interworking with the conversion into chargeband numbers or meter-pulse units is not supported. The following functionality is provided: i) ii) iii) apply a call attempt charge for un

46、successful calls; apply a call setup charge (once) at start of charging; apply an initial communication tariff at start of charging and an (optional) next tariff at an absolute time during the call; iv) change immediately the current tariff; v) change the next tariff at an absolute time during the c

47、all; vi) change immediately the current tariff and change the next tariff at an absolute time during the call; vii) delete the next tariff and the corresponding absolute switchover time; viii) apply immediately an add-on charge (either a number of pulses or an amount of currency) during the call. Th

48、is add-on charge is additive and does not change the tariff in force; acknowledge the received charging information; differentiation as to whether the charging information is to be used for advice of charge purposes only, or for subscriber charging purposes (which would also allow it to be used for

49、advice of charge purposes); perform validation (e.g. check range of parameters, check whether a request from a certain network operator can be accepted); xii) apply a “one time charge“ (i.e. non-periodic charge/flat rate) as a minimum communication charge at start of charging; xiii) stop charge generationhegistration for a Tariff that belongs to a operator at the end of a connection configuration without clearing the complete call, that means connection A-party to CCP shall be kept; xiv) invoke and start charge generationhegistration for a Tariff that belongs to
