METHOD, APPARATUS, AND SYSTEM FOR USING TCP/IP AS THE TRANSPORT LAYER FOR SCREEN PHONES

摘要

This invention relates to the field of telecommunications using TCP/IP as the transport layer protocol. More particularly, this invention is a method and apparatus for sending application information from an ADSI server to an ADSI compatible device using TCP/IP. With reference to Fig. 5, application information (207) is encapsulated according to ADSI message layer (105) and datalink layer (103) protocol specifications. The resulting bit stream (513) is passed to a socket interface (511) to form a TCP/IP bit stream (515) of application information. The TCP/IP bit stream (515) is sent through a TCP/IP network from one ADSI compatible device (501) to another ADSI compatible device (503). The application information is processed in the same manner, but in the opposite order at the receiving device (503).
