发明名称 Enhancements to IP Multimedia Subsystems (IMS) Emergency Services Architecture
摘要 Embodiments contemplate methods and systems that may route an emergency call from an enterprise user and/or a user in a private number plan, or an emergency call that may be initiated by a service on behalf of the user. Architectural extensions to the IMS emergency services architecture may allow an emergency call to be handled in a home network or a local network in which the user may be visiting (e.g., roaming) such that appropriate public safety systems may be apprised of the emergency communication.
