METHOD, SYSTEM AND APPARATUS FOR EMERGENCY CALL HANDLING

摘要

A method, system and apparatus are provided for handling emergency calls at a policy server. The policy server receives a request to establish an emergency call for a mobile device, from a service provider server. The request is received in an external format. The policy server converts the request to an internal format, and processes the internal request to generate an internal answer. The internal answer indicates whether the emergency call is permitted or denied. The policy server converts the internal answer to the external format, and transmits the converted answer to the service provider server. When the emergency call is permitted, the policy server deploys one or more policy rules to a gateway server.
