Abstract

A method, user equipment and non-transitory computer readable memory for establishing an emergency service using a wireless network includes unilaterally deactivating, at the user equipment when the user equipment needs to establish an emergency service, at least one active context with the wireless network without deactivating at least one other active context. Thereafter directing to the wireless network, a request to establish the emergency service that identifies the emergency service and one or more contexts that remain active after the unilateral deactivation of the at least one active context by the user equipment, synchronizing, in response to and based on the request, current context status information of the user equipment with the wireless network, and then establishing the emergency service using the wireless network with which the active context was deactivated.
