17、mmission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity.

18、ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee,

19、ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to nati

20、onal bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible f

21、or identifying any or all such patent rights. ISO/IEC 15505 was prepared by ECMA (as ECMA-241) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. This third edit

ISO/IEC 15505:2003(E) vi ISO/IEC 2003 All rights reserved Introduction This International Standard is one of a series of Standards defining services and signalling protocols applicable to Private Int

23、egrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This International Standard specifies the Message Waiting Indication supplementary service. This Int

24、ernational Standard is based upon the practical experience of ECMA member companies and the results of their active and continuous participation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus

25、 ISO/IEC 2003 All rights reserved 1 1S c o p e This International Standard specifies supplementary service Message Waiting Indication (SS-MWI), which is related, but not limited, to various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO

26、/IEC 11574. This supplementary service MWI enables a Served User to be sent a Message Waiting Indication and also enables this Message Waiting Indication to be cancelled. Service specifications are produced in three stages, according to the method described in ETS 300 387. This International Standar

27、d contains the stage 1 and stage 2 specifications of SS-MWI. The stage 1 specification (clause 6) specifies the supplementary service as seen by users of PISNs. The stage 2 specification (clause 7) specifies the functional entities involved in the supplementary service and the information flows betw

28、een them. 2 Conformance In order to conform to this International Standard, a stage 3 standard shall specify signalling protocols and equipment behaviour that are capable of being used in a PISN which supports the supplementary service specified in this International Standard. This means that, to cl

29、aim conformance, a stage 3 standard is required to be adequate for the support of those aspects of clause 6 (stage 1) and clause 7 (stage 2) which are relevant to the interface or equipment to which the stage 3 standard applies. 3 Normative references ISO/IEC 11574:2000, Information technology - Tel

39、1.1 General description The supplementary service MWI enables a Served User to be sent a Message Waiting Indication and also enables this Message Waiting Indication to be cancelled. NOTE - The Message Waiting Indication is sent on activation by the Message Centre. NOTE - The Message Waiting Indicat

40、ion is cancelled on deactivation by the Message Centre. A Served User can receive separate MWIs for each of the services for which there is a message waiting. NOTE - A service for which there is a message waiting would normally use the related basic service to retrieve that message. 6.1.2 Qualificat

41、ions on applicability to telecommunication services This supplementary service does not apply directly to any basic telecommunication service. However, a MWI relates to a basic service for which there are messages waiting. 6.2 Procedures 6.2.1 Provision / withdrawal SS-MWI may be provided or withdra

42、wn after pre-arrangement with the service provider or may be generally available to all users. 6.2.2 Normal procedures 6.2.2.1 Activation, deactivation and interrogation The PISN shall provide activation / deactivation by the Message Centre. In addition, the PISN may provide interrogation by the Ser

43、ved User.ISO/IEC 15505:2003(E) ISO/IEC 2003 All rights reserved 3 To activate SS-MWI, the Message Centre shall supply the PISN number and the service for which there is a message waiting and may, as an implementation option, add any combination of the following pieces of information: the identity of

44、 the Message Centre; the number of messages waiting for the Served User for that service; the address of the user that left a message; the time when a message was left; the priority of the highest priority message waiting for that service. After activation, SS-MWI may be activated again whenever the

45、 number of waiting messages changes. To deactivate SS-MWI, the Message Centre shall supply the PISN number and the service for which there is no longer a message waiting. As a result of activation, a MWI shall be sent to the Served User. The MWI may include information on messages waiting, if provid

46、ed by the Message Centre. As a result of deactivation, the MWI at the Served User, for the service concerned, shall be cancelled. When the Message Centre activates or deactivates SS-MWI at the Served User, it shall be provided with an indication of acceptance. When the Served User interrogates SS-MW

47、I for a particular service, the Message Centre shall provide the Served User with an indication of whether SS-MWI is activated for that service and may add, as an implementation option, any of the following information: the identity of the Message Centre; the number of messages waiting; the address

48、of the user that left a message; the time when a message was left; the priority of the highest priority message waiting. When the Served User interrogates SS-MWI for all services, the Message Centre shall provide the Served User with a list of services for which SS-MWI is active and, as an implement

49、ation option, for each service, any of the additional information listed above. 6.2.2.2 Invocation and operation Not applicable. 6.2.3 Exceptional procedures 6.2.3.1 Activation, deactivation and interrogation If the Served User cannot accept activation or deactivation, then the Message Centre shall be informed and may also be given the reason. If the PISN cannot accept interrogation, then the Served User shall be informed and may also be given a reason. 6.2.3.2 Invocation and operation Non
