Problems solved by technology

Reflected in the specific operation, the P-CSCF failed to judge in step 102: the UE did not recognize the request message as an emergency service request message, and rejected the UE's emergency service request; and the P-CSCF rejected the service request After receiving the message, the UE cannot recognize the emergency service identifier carried in the rejection message, that is, the P-CSCF does not know the capabilities supported by the UE when it chooses to reject the request message, so the emergency call fails, which may cause serious consequences
[0011] In addition, in the prior art, there is a way to choose whether to reject or receive the service request message according to the access type of the terminal, but up to now, the P-CSCF It is still unable to identify the access type of the terminal itself, so the method given in the prior art to choose whether to reject or receive the service request message according to the access type of the terminal cannot be implemented

Embodiment Construction

[0069] The basic principle of the present invention is: change the existing technology and only give the situation that the network chooses to send emergency service notification information to the user terminal at will or not, and the network decides how to choose according to the emergency service information, and coordinates the network and the terminal Communication and cooperation when performing emergency services, so that the user terminal can continue to process the current request message when it is rejected by the network, and can still route the current request message to the emergency service when the user terminal cannot recognize the emergency service notification information center.

[0070] The present invention can realize as follows generally:

[0071] The network receives and checks the message sent by the user terminal, and determines that the message is an emergency service request message when the message does not carry an emergency service identifier and...

Abstract

This invention discloses a process method for urgent services including: a UE sends a request message to a network, which judges if the request message is urgent and judges that the UE does not identify its request message an urgent one and then processes it correspondingly.

Description

technical field [0001] The invention relates to a communication method and system thereof, in particular to an emergency service processing method and a communication network. Background technique [0002] The emergency business in communication refers to the business that the communication network provides emergency assistance to the individual / public in the critical situation where personal / public health and safety, life / property are in danger. For example, the common 110 alarm service, 119 fire alarm service, etc. [0003] In emergency business processing, the communication network should provide high-priority communication services for emergency business. The basic flow of emergency service processing is as follows: User Equipment (UE, User Equipment) initiates a call; the communication network routes the emergency service request message to the most appropriate public safety access point (PSAP, Public Safety Answering Point); Information and emergency service types, t...
