ETSI TS 101 470

Total Conversation, as defined in Recommendation ITU-T F.703 [2], is a combination of three media in aconversational call: video, Real-Time Text and audio. ETSI TS 101 470 defines conditions for using TotalConversation for emergency services with more media than in the regular voice call providing opportunities to morerapid, reliable and confidence-creating resolution of the emergency service cases compared to plain voice emergencycalls, and especially for enabling access of emergency services or making them more usable for those persons who mayhave little or no use of voice telephony because of disabilities related to hearing, speech or other human communicationfunctions.

The present document addresses the organization of Public Safety Answering Points (PSAP) and the potential impacton overall organizations of emergency services for handling Total Conversation calls. The present document alsoaddresses functional requirements regarding the interface to the PSAP, the connection to external supporting services,the transferring and sharing of the call between call handling organizations, the call logging and call recording at thePSAP, the PSAP call back aspects and specific call routing and location information provision aspects for these TotalConversation calls. The present document refers to existing standards relevant for Total Conversation user terminalsand serving networks to facilitate a Total Conversation emergency call. The present document does not imply anyrequirements on user terminals in general to be Total Conversation terminals.

The service specified here is one solution for accessible emergency services intended to fulfil requirements in the EUUniversal Service Directive [i.1] and [i.2]. The present document does not preclude that other solutions may be possibleand can be specified and implemented.

Due consideration is taken of related standardization (e.g. 3GPPTM and IETF) and work in other bodies (e.g. the ExpertGroup on Emergency Access (EGEA) and the European Emergency Number Association (EENA)).
