Embodiment approach

[0030] Fig. 2 shows that the present invention handles the schematic flow chart of emergency call, below in conjunction with Fig. 2 illustrates the specific embodiment of the present invention, and its steps are:

[0031] Step 201: UE sends RRC connection establishment request to RNC;

[0032] Step 202: RNC judges whether the establishment reason is an emergency call, if so, execute step 204, otherwise execute step 203;

[0033] Step 203: Execute the RRC connection establishment process of the general call;

[0034] Step 204: The RNC judges whether there is a downlink channelization code resource, if not, execute step 205, and if so, directly execute step 206;

[0035] Step 205: RNC releases a general call with the lowest priority;

[0036] Step 206: RNC allocates resources for the emergency call, and establishes an RRC connection;

[0037] Step 207: UE sends a call management service request message to CN;

[0038] Step 208: CN judges whether the call management service i...

Abstract

A method for processing emergency call in wideband CDMA system includes configuring an emergency call indication cell in setup request message of radio access load to indicate whether the call is an emergency call or not, setting content of indication cell on said emergency call to be true after emergency call is identified out and sending said message containing said cell to radio network controller by core network device, identifying out said call to be emergency call by said controller according to said cell then distributing radio resource onto said emergency call to set up radio load preferentially by said controller.

Description

technical field [0001] The invention relates to an emergency call processing method in a WCDMA (Wideband Code Division Multiple Access) system, in particular to an emergency call processing method in the case of concurrent services in the WCDMA system. Background technique [0002] Emergency calls include fire alarm, bandit police, medical assistance, and disaster events, 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 treatment can be obtained in time when an emergency occurs. [0003] Different communication systems have different methods for handling emergency calls. In a WCDMA system, the general call flow is shown in Figure 1, and the flow is as follows: [0004] Step 101: The user equipment (User Equitment, hereinafter referred to as UE) prepares to initiate a call, and sends a connection establishment (hereinafter referred to as RRC) request to ...
