Specialist Task Force 321:
TISPAN Emergency call standards development of Location Information
and protocol support for Emergency Communications 

Who we are:

Team Leader: Jim Price See our questionnaire !
Team Member: Pietro Schicker  

What we do :

The activity will prepare the requirement documentation to enable standards that allow a secure network and user environment for the support of all the emergency services in eEurope (eBusiness, eGovernment, etc.).

This will include an analysis of the requirements and protocols for interworking and mapping with regard to the location information and Mobile Location Protocol (MLP) for the interconnection interface between Fixed and Mobile networks for Emergency Communications.

There will then be an appraisal of the ongoing work within the various standards bodies to interwork the location information that could be generated by an NGN or other type of network such that the Emergency service(s) only need to go to one place to obtain the location information. At present there is no international standard for PSAPs currently available and this is now being worked on in ETSI TC TISPAN with ETSI 3GPP, and the experts are currently engaged with ongoing work in the IETF ECRIT Working Group.

This is not an exhaustive list.  Additional applications may be identified in the course of the activity.

Work Items:

Read our Terms of Reference

Why we do it:

In order to effectively deliver emergency services to the location of an emergency, it is necessary for the emergency service to have accurate information that enables them to identify the location. In many circumstances, the person reporting the emergency can provide the emergency service with information about the location of the emergency. However this information could be inaccurate and the nature of the emergency may prevent the person from being able to communicate that information. For this reason it is essential that emergency services are able to access accurate location information.

Questionnaire on Emergency Caller Location

STF321 is short of information from a number of countries. We have produced a short questionnaire in an attempt to correct this. All readers are invited to respond to any or all of the questions with details of the situation in their countries, adding any extra information they feel will be useful. 

Please send your answer directly to the STF Leader, Jim Price at or
