Motivation

Work on modification of call signalling protocols to support Emergency Telecommunications Service (ETS) has been in progress for many years. More recently this has been joined by work on Telecommunications for Disaster Relief (TDR), and work on early warning systems has just started. Now this work is starting to spread below the service control layer, and thus is affecting a number of Questions. It will be useful to have a resource permanently in place to coordinate this work so that the implementation of specific capabilities can be defined in an integrated rather than piecemeal fashion. This Question provides the required resource. Emergency Communication capabilities are currently embedded in Recommendations that are the responsibility of other Questions, so that this Question will not initially have responsibility for Recommendations of its own. However, it will be responsible for ensuring the maintenance of existing Emergency Communication capabilities in Recommendations Q.931, Q.761, Q.762, Q.763, Q.764, Q.1902.1, Q.Q.1902.3, Q.1902.4, Q.1950, Q.2630.3, Q.2931, and Q-Series Supplement 53.

Question

Study items to be considered include, but are not limited to:

• What is the content of the work program of the Study Group required to standardize the Emergency Communication capabilities called for by the plans set by the respective lead Study Groups?
• What signalling requirements must be defined in support of Emergency Communications?
• What Recommendations must be created in response to these requirements because the work is not covered by other Questions in the Study Group;
• What changes should be proposed to the overall plans maintained by the respective lead Study Groups, to provide for new capabilities, to provide better realization of capabilities already being standardized, or to remove obsolete content.

Tasks

Tasks include, but are not limited to:

• Analysis of Emergency Communication capabilities to which priority has been assigned by their respective lead Study Groups to determine the specific study tasks that must be added to the work plans of individual Questions of the Study Group.
• Ensuring that the necessary communications take place at the technical level between the Questions of the Study Group, so that their work of realization of Emergency Communication capabilities is effective, consistent, and complete.
• Similarly ensuring that the necessary communications take place at the technical level between the Questions of the Study Group, Questions of other Study Groups, and other groups defining standards relating to Emergency Communication, as identified by the plans maintained by the respective lead Study Groups.
• Reviewing ETS and TDR capabilities already implemented in Recommendations within the area of responsibility of the Study Group, to ensure that they are still relevant and effective.
• Contributing to the development and maintenance of the plans which are the responsibility of the respective lead Study Groups for Emergency Communication, including the proposal of new content when this seems appropriate.
• Creation of Supplements defining signalling requirements in support of Emergency Communications.
• Creation of new Recommendations dealing with Emergency Communication when these fall outside the scope of other Questions of the Study Group.

Relationships

Recommendations:

The Question is responsible for maintenance of the ETS and TDR aspects of the following Recommendations: Q.931, Q.761, Q.762, Q.763, Q.764, Q.1902.1, Q.Q.1902.3, Q.1902.4, Q.1950, Q.2630.3, Q.2931, and Q-Series Supplement 53. The work that the Question oversees operates within the framework defined by Recommendation Y.1271 and draft new Recommendation ITU-T Rec. Y.NGN-ET-Tech.

Questions:

All other Questions of the Study Group. Questions specifically relating to ETS and TDR in other Study Groups.

Study Groups:

• Lead Study Groups for ETS and TDR respectively.
• Lead Study Group(s) for any other aspect of Emergency Communication.

Standardization bodies:

• Activities of IETF, IEEE, and regional standards bodies dealing with ETS and TDR or capabilities required to implement them.
