About This Item
Full Description
This TS includes information applicable to network operators, service providers, terminal and network manufacturers.
This TS contains the core requirements for the Global Text Telephony feature, which are sufficient to provide a complete feature to incorporate in conversational services.
This TS defines the requirements for GTT to be understood as a framework to enable real-time transmission of text, for the purpose of a text based or text supported conversation between users. Text may be transported alone or in combination with other media in the session, especially video and voice.
Thus the GTT enables text conversation to be included in any mobile conversational service.
Interworking with existing text telephony in PSTN as well as emerging forms of standardised text conversation in all networks is within the scope of this document. Interoperation with Multimedia Messaging Services is also within scope of this feature.
Note: The Global Text Telephony feature may be enhanced due to e.g. operator's or regulator's requirements, however such additional functionality shall not compromise conformance to the core requirements documented in this TS.
