This Recommendation forms part of the requirements for specifying the radio interfaces of IMT-2000. IMT-2000 will operate in the worldwide bands ide
5、ntified by Radio Regulations Provision No. 746A (1 885-2 025 MHz and 2 110-2200 MHz, with the satellite component limited to 1 980-2 O10 MHz and 2 170-2 200 MHz). The subject matter of IMT-2000 is complex and its representation in the form of a Recommendation is evolving, To maintain the pace of pro
6、gress on the subject it is necessary to produce a sequence of Recommendations on a variety of aspects. The Recommendations suive to avoid apparent conflicts between themselves. Nevertheless, future Recommendations, or revisions, will be used to resolve any discrepancies. IMT-2000 management is consi
7、dered as providing the various functions necessary for planning, provisioning, installation, operation, maintenance, administration and customer services. To provide such functions, a service-specific network which permits the exchange and processing of management information between IMT-2000 equipm
8、ent andor operations systems is needed. This network could be established based on the TMN concept. TMN has been studied in the ITU Telecommunication Standardization Sector (ITU-T) which has developed the philosophy and concept of TMN and made some TMN relevant Recommendations i. The basic concept b

The m
11、ethodology described in ITU-T Recommendation M.3020 2 is used to define management requirements, management services, management functions, information models, and management protocols related to the management of IMT-2000. This framework is the initial Recommendation on IMT-2000 management and iden
12、tifies objectives for IMT-2000 management, and provides guidelines for the specification of Recommendations on IMT-2000 management, particularly a TMN management service on IMT-2000. Other Recommendations on IMT-2000 management will be produced by ITU in the near future. 3 Structure of the Recommend
13、ation Section 4 of this Recommendation, provides a list of related documents. In 0 5, a list of definitions commonly used throughout this Recommendation is given. Section 6 states the considerations that have been taken into account in the creation of this Recommendation. Section 7 identifies object
14、ives for IMT-2000 management standardization, general requirements for IMT-2000 management, and provides principles for the specification of IMT-2000 management Recommendations, particularly the TMN management service on IMT-2000.

IT-R M.1168 271 7.1.2.2.2 Charging and billing In IMT-2000 there will exist different possibilities to charge for calls: a) Normal case In this case usage records are created by the network operators.
48、These usage records will be collected by the appropriate service providers for billing. b) Hot billing er the call (credit card callings) In this case the network operator bills the credit card agency for the call after collection of all relevant usage records. c) Hot billing during the call (prepai
49、d cards or cash) In this case the network operator deducts units from the prepayment while the call is in progress. IMT-2000 management should provide the means to apply proper charging according to cases a) to c). Usage records are transferred to the service provider of the involved users. Originating, transit and terminating IMT-2000 operators should be able to do usage metering. Usage metering of network resources for the purpose of billing shall be the responsibility of the network operator. IMT-2000 management should enable IMT-2OOO operators to register certain kinds
