In 1995, Ericsson introduced the yangbertujuan a project to develop common protocols, concepts, namely the value addition of services on the mobile network. This protocol, called Intelegent Terminal Transfer Protocol (ITTP), can handle communication between two nodes that use the service applications.
1996 and 1997, Unwired Planet, Nokia and several other companies launched the concept in adding additional value services on the mobile network. Unwired Planet issued a Handheld Device Markup Language (HDML) and Handheld Device Transport Protocol (HDTP). Almost the same with HTML and HTTP, as a design tool and protokolnya.
March 1997, Nokia officially removing the concept of Smart Messaging services, Internet access is designed for GSM mobile phone. Communication between a mobile user and the server consists of the Internet Information using SMS and a markup language called Tagged Text Markup Language (TTML).
With that concept in various ways, you risk the user is in pieces, according to certain concepts.
