The
11、 ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standar
12、dization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information t
13、echnology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.

48、or an evolution towards a multi-service and multi-network provider environment for open services as follows: convergence services should be available across multiple networks; IP-based access networks should support convergence services using both fixed and mobile terminals. IP technology is used by
49、 application service providers and network providers in different network types as follows: wireline networks (e.g., operated by companies offering telephony services and other advanced services); cable networks (e.g., operated by television service providers); wireless networks (e.g., operated by cellular/mobile companies along with new nomadic capabilities).
