These features enable IMT to address evolving user needs and the capabilities of IMT systems are being continuously enhanced in line with user trends and technology d

16、evelopments. IMT will operate in the worldwide bands identified in the Radio Regulations. IMT is defined by a set of interdependent ITU Recommendations and Reports of which this one is a member. This Recommendation contains definitions of terms and abbreviations used in the ITU Recommendations and R

17、eports on IMT. 2 Scope This Recommendation consists primarily of those terms and definitions that are considered essential to the understanding and application of the principles of IMT. Although these terms may already be defined in other ITU Recommendations, the definitions given here were drawn fr

18、om the essential Recommendations and Reports related to IMT. Nevertheless, the terms defined below are not necessarily exclusive to IMT, and so far as they are relevant, may also apply to other communication systems and services. 3 Structure of the Recommendation Definition of Terms Section 4.1 cont

19、ains the definitions of terms used in IMT Recommendations and Reports. List of abbreviations and acronyms Section 4.2 contains a list of abbreviations and acronyms which are used in IMT Recommendations and Reports. 4 Recommendation For the purposes of Recommendations and Reports related to IMT, the

20、following terms, definitions, abbreviations and acronyms are recommended to be used with the meanings defined below. These terms, definitions, abbreviations and acronyms are not necessarily exclusive to IMT, and so far as they are relevant, may also apply to other communication systems and services.

21、 It is further noted that these terms, definitions, abbreviations and acronyms are defined within a specific context as indicated in the sections below and thus may be found in more than one section of this Recommendation.

30、ch the mobile station requests to the network. Bearer service: A type of telecommunication service that provides the capability for the transmission of information between user-network interfaces. NOTE 1 The ISDN connection type used to support a bearer service may be identical to that used to suppo

31、rt other types of telecommunication services. 1See also 5.X.2 of Recommendation ITU-R M.1457. 4 Rec. ITU-R M.1224-1 Billing: A function whereby charging information generated by the charging function is transformed into bills requiring payment. Billing also includes collecting payments from the subs

32、cribers. Broadcast call: A point-to-multipoint call in which the same information is transmitted simultaneously by the calling user to all intended users. Broadcast control channel (BCCH): The BCCH provides the broadcast capability for a variety of information streams from base stations to mobile st

33、ations, including information necessary for the MS to register in the system. Call: The use, or possible use, of one or more connections set up between two or more users and/or services. Call control (CC): A function in layer 3 which carries out call processing. NOTE 1 The term “layer” refers to the

Call transfer (CT): A supplementary service or a service feature which enables the served mobile user to transfer an established incoming or outgoing call to a third party. Call waiting (CW): A supplementary ser

Subsequently, the subscriber can either answer, reject, or ignore the incoming call. Calling party identification presentation (CPIP): A supplement

37、ary service which allows a UPT user to specify that the identity of the calling user or terminal access shall be announced on the alerting terminal in the case of an incoming UPT call. The identity of terminal access must never be presented if the calling party is a UPT user. Capability: The ability

38、 of an item to meet a service demand of given quantitative characteristics under given internal conditions. Cell: The radio coverage area of a satellite spot beam or a base station, or of a subsystem (e.g. sector antenna) of that base station corresponding to a specific logical identification on the
