29、36BS ISO/IECTR15410:1998 vi BSI 03-2000 Foreword ISO (the International Organization for Standardization) and IEC (theInternational Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of

30、 International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in l

31、iaison 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, ISO/IEC JTC1. The main task of technical committees is to prepare International Standards, but in exceptional circumstances a technical committee may

32、 propose the publication of a Technical Report of one of the following types: type1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type2, when the subject is still under technical development or where for any other reason the

33、re is the future but not immediate possibility of an agreement on an International Standard; type3, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example). Technical Reports of types1 and2

34、 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical Reports of type3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. ISO/IEC TR15410, which is a

35、Technical Report of type3, was prepared by Joint Technical Committee ISO/IEC JTC1, Information technology, Subcommittee SC6, Telecommunications and information exchange between systems.BSISO/IECTR15410:1998 BSI 03-2000 1 1 Scope This Technical Report (TR) analyses the requirements for the standardiz

36、ation of networking functions to support mobility within one or more Private Integrated Network Exchanges (PINXs) of a Private Integrated Services Network (PISN). It covers both Wireless Terminal Mobility (WTM) and Private Personal Mobility (PPM). WTM is a function that allows users of Wireless Term

37、inals (WT) to make and receive calls at any compatible radio access within the network. Standards for WTM should be independent of the access technology used to support the WTs. PPM enables users of a PISN to register at any suitable terminal (wired or wireless) within the network for the making and

38、/or receiving of calls. This Technical Report covers the following subjects for both WTM and PPM: Registration procedures; Procedures for incoming and outgoing calls; Access security procedures (identification and authentication); Requirements for numbering, addressing and signalling; Requirements f

39、or management, administration and operation. 2 References ISO/IEC11571:1994, Information technology Telecommunications and information exchange between systems Numbering and sub-addressing in private integrated services networks.

48、ns services of a PISN via a radio interface. 4 Wireless Terminal Mobility (WTM) the ability of a wireless terminal to be in continuous motion whilst accessing and using the telecommunication services offered by the PISN, as well as the capability of the network to keep track of the location of the w

49、ireless terminal within the coverage area of the radio system used. 5 Coverage area the area over which reliable communication can be established and maintained. 6 Fixed part a physical grouping of some or all of the fixed component parts of a mobile radio system. These would include one or more pieces of radio equipment attached to an antenna system. It could also include common control functions and interfaces to the PINX. 7 Function a set of processes defined for the purpose of achievin
