Deactivating existing bearer/context for emergency bearer establishment

A portable telecommunications user equipment, comprising:

• a processing system comprising at least one processor and at least one memory storing a computer program;
• the at least one memory with the computer program being configured with the at least one processor to cause the user equipment to at least:
• unilaterally deactivate at least one active context with a wireless network without deactivating at least one other active context when the user equipment needs to establish an emergency service;
• thereafter
• direct to the wireless network, a request to establish the emergency service and 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, such that in response to and based thereon, current context status information of the user equipment is synchronized with the wireless network, and then
• establish the emergency service using the wireless network with which the active context was deactivated.

A non-transitory computer readable memory tangibly storing a computer program executable by at least one processor, the computer program comprising:

• code to be executed on a processing system of a user equipment, the code being for:
• unilaterally deactivating, 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 and 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.
