12、unication services including advanced mobile services, supported by mobile and fixed networks, which are increasingly packet-based. IMT systems support low to high mobility applications and a wide range of data rates in accordance with user and service demands in multiple user environments. IMT also
13、 has capabilities for high quality multimedia applications within a wide range of services and platforms, providing a significant improvement in performance and quality of service. 2 Rec. ITU-R M.1224-1 Key features a high degree of commonality of functionality worldwide while retaining the flexibil
14、ity to support a wide range of services and applications in a cost efficient manner; compatibility of services within IMT and with fixed networks; capability of interworking with other radio access systems; high quality mobile services; user equipment suitable for worldwide use; user-friendly applic
15、ations, services and equipment; worldwide roaming capability; enhanced peak data rates to support advanced services and applications. 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.

26、information at call set-up time. Anonymity: The process of hiding a users identity, and location. Asynchronous transfer mode (ATM): A transfer mode in which the information is organized into cells; it is asynchronous in the sense that the recurrence of cells depends on the required or instantaneous
27、bit rate. Statistical and deterministic values may also be used to qualify the transfer mode. Authentication: The process of verifying the identity of a user, terminal, or service provider. Authentication algorithm: A sequence of security information known by the user, or maintained in an access dev
28、ice. It is used to provide secure access to the service. This may involve complex algorithms.

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
34、 OSI (Open Systems Interconnection) reference model. Call forwarding (CF): A supplementary service or a service feature which allows the user to have his incoming calls addressed to another number. Call hold (CH): A supplementary service which allows a served mobile user to interrupt communication o
35、n an existing active call and then subsequently, if desired, re-establish communication. 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
36、vice or a service feature which permits the possibility for a mobile user to be notified of an incoming call while the termination is in the busy state. 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
39、 radio path, whichever is smaller. NOTE 1 Every mobile station in a cell may be reached by the corresponding radio equipment. Charging: A function, whereby information is gathered, recorded or transferred in order to make it possible to determine and to collate usage for which the subscriber may be

Circuit transfer mode: A transfer mode in which transmission and switching functions are achieved by permanent or quasi-permanent allocation of channels, bandwidth or codes between identified points of a connection. Closed user group (CUG): A supplementary service or a service feature which
41、allows users to form groups to and from which access is restricted. A specific user may be a member of more than one CUG. Members of a specific CUG can communicate among themselves but not, in general, with users outside the group. NOTE 1 Specific users of a CUG may have additional capabilities or a
42、dditional restrictions that apply. Rec.

Compatibility: A degree of transparency sufficient to support an acceptable grade of service with respect to a connection between system entities. Full compatibility implies full transparency. Completion of calls to busy subscri
46、ber (CCBS): A supplementary service which allows a calling user to be informed upon encountering a busy destination and to complete the call when that destination becomes free, without re-dialling. Confidentiality: A property by which information relating to an entity or party is not made available
47、or disclosed to unauthorized individuals, entities or processes. Connectionless service: A service which allows the transfer of information among users without the need for end-to-end calls establishment procedures. Connectionless services may be used to support both interactive and distribution ser
