Evaluation of short-term interim techniques for multimedia emergency services

 This white paper evaluates options for an interim solution that can be supported by the both the existing wireless networks and Public Safety Answering Points (PSAPs).
Any interim solution chosen should have minimal impacts on the entire emergency services system. End user devices and origination networks should use existing technologies and should be available to support an interim solution as quickly as possible. Likewise, the emergency services networks should require little to no change.
The focus of this white paper is based on the use of existing technologies such as GSM and UMTS circuit and packet services. The LTE and IMS technologies are not within the scope of this white paper even though there are some LTE and IMS deployments in existence.
It is expected that the long term Multimedia Emergency Services (MMES) solution being specified in 3GPP will be supported in the LTE and IMS environments.
