Abstract

A method for automatically connecting a call in a mobile station during an emergency situation. In the method a call connection request message including a service identifier previously set for automatic call connection and a password is received. Next, whether the call connection request message is valid is determined using the password included in the received call connection request message. If the call connection request message is valid, devices for outputting an alert signal of the mobile station are turned off, and a response signal for call connection in response to the call connection request message is automatically generated.

Claims

1. A method for connecting a call in a mobile station during an emergency situation, comprising the steps of:

receiving a call connection request message including a service identifier, which is previously set by a user for an automatic call connection, and a password;

determining whether the call connection request message is valid using the password included in the received call connection request message;

turning off power for any device for outputting an alert signal of the mobile station, if the call connection request message is valid; and

automatically generating a response signal for call connection in response to the call connection request message.

2. The method of claim 1, further comprising the step of setting a reception level of a microphone of the mobile station to maximum value, if it is determined that the call connection request message is valid.

3. The method of claim 2, further comprising the step of rejecting the call connection request message not including the service identifier, if the user of the mobile station has set information for automatic call connection.

4. The method of claim 1, wherein the service identifier included in the call connection request message and a phone number are input along with a phone number of the mobile station by a user who generated the call connection request message.

5. The method of claim 1, wherein the step of determining whether the call connection request message is valid comprises the steps of:

comparing the password included in the call connection request message with a password previously stored in the mobile station; and

determining that the call connection request message is valid, if the password included in the call connection request message is identical to the password previously stored in the mobile station.

6. The method of claim 1, wherein the any device for outputting the alert signal include at least one of a speaker, a lamp, a display, and a vibrator of the mobile station.

7. The method of claim 1, further comprising the steps of:

determining whether the mobile station is turned off, if the call connection request message is valid; and

if the mobile station is turned off, turning on power for only a call connection-related device and a microphone of the mobile station and maximizing a volume of the microphone.

8. The method of claim 1, further comprising the step of rejecting the call connection request message not including the service identifier, if the user of the mobile station has set information for automatic call connection.
