Embodiment Construction

[0040] The emergency call processing method in the WCDMA system of the present invention reserves the highest level of priority (priority 1 in the embodiment of the present invention) at the CN side for emergency calls of the present invention, and other 14 levels of priority (in the embodiment of the present invention) In the embodiment of the present invention, priority 2 to priority 15) are used for general calls of subscribers.

[0041] RNC receives the RRC connection establishment request, and judges whether it is an emergency call according to the establishment reason in the message. If it is an emergency call, in the case of system congestion, it will initiate resource preemption for general calls and allocate resources for emergency calls; call, resource preemption will not be initiated.

[0042] CN receives the CM SERVICE REQUEST message, and judges whether it is an emergency call according to the requested service type: if it is an emergency call, set the priority to...

Abstract

The invention relates to a method for processing emerge call in WCDMA system, for processing the emerge call of parallel service of WCDMA, wherein the corn network sets highest priority for the wireless access load of emerge call, and it comprises following steps: 1, wireless network controller processes the RRC connection request of said emerge call; 2, the corn network sets the priority of emerge call as highest priority; 3, the wireless network controller distributes resource for emerge call. The invention sets the priority of emerge call at the network side as highest one, to improve the connection rate of emerge rate and improve the service quality of operator.

Description

technical field [0001] The invention relates to an emergency call processing method, in particular to an emergency call processing method used in a WCDMA system. Background technique [0002] Emergency calls include fire alarms, bandits, medical assistance, disasters, etc. The public communication system must provide emergency call services, and the priority of emergency calls is higher than that of general calls, so that assistance and assistance can be obtained in time when an emergency occurs. deal with. [0003] Different communication systems handle emergency calls differently. In a WCDMA system, the general call flow is as follows: figure 1 shown, including the following steps: [0004] Step S100, the UE (User Equipment, user device) prepares to initiate a call, and sends an RRC (Radio Resource Control, radio resource control) connection establishment request to the RNC (Radio Network Controller, radio network controller), and the request message contains an establi...
