39、national Electrotechnical Commission) 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 fi
40、elds of technical activity. 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
41、 joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical comm
42、ittee are circulated to national 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 International Standard may be the subject of patent rights. I

44、18021:2002(E) vi ISO/IEC 2002 All rights reserved IntroductionIn recent years, MoBile Tools (MBT), typically personal digital assistants (PDA), smart phones (mobile phoneswith web-browsing, e-mail, or some other network function) and other small size devices have becomeincreasingly popular. MBT are
45、constrained by requirements of low power consumption, small physical size, lightweight, limited memory, low CPU processing power and restricted display screen size. To enable a variety ofservices and applications to be used comfortably and efficiently on hardware-restricted MBT, they are typicallyop
46、erated in conjunction with other devices via communication links. When the MBT works in conjunction withserver machines or other computers, it becomes more powerful and more useful. Due to these restrictions, it ismore difficult to achieve compatibility and interoperability than it would be in a lar
47、ge device. In order to achievecompatibility and interoperability, a different approach than that used for larger equipment is necessary.When the MBT exchanges data (e.g. address data, schedule data, or sales data, etc.) with other devices via apotentially unreliable or narrow communication line, as
48、in wireless communications, user interfaces formanagement of database communications of mobile tools are required to meet users needs such as fastresponse, high usability, reliability and easy-to-use features. Standardizing these new user-interfaces will be verybeneficial and convenient for MBT user
49、s.A MoBile Tool client (MBT client) is defined as the software of an MBT that performs client operations with otherdevices via communication links. A MoBile Tool server (MBT server) is defined as the software of a device thatacts as a server with the MBT client via a communication link. An MBT server can be run on a multi-accessibleserver or on another MBT. When an MBT client communicates with another MBT that has these MBT servercapabilities, the former acts as the MBT client and the latter as the MBT server, thereby allowing
