Abstract
Methods and systems for disabling supplementary services that interfere with callback from a public safety answering point are described. In one embodiment, a method is performed by a system operating in a home network domain of a wireless network. The home network domain includes a home subscriber server (HSS) which maintains user profiles associated with a plurality of communication devices. The user profiles define services enabled for such communication devices. The method includes: detecting an emergency registration associated with an emergency call placed from the communication device; and in response to detecting the emergency registration associated with the emergency call, updating, at the HSS, the user profile associated with the communication device which placed the emergency call to disable at least one supplementary service for that communication device.
