Abstract

A mobile communication system and method for lengthening an incoming call waiting time and a mobile terminal therefor are provided to increase a call connection success probability and thus make more profit at the side of a communication network provider. When an MSC(Mobile Switching Center) receives a call connection request from an origination terminal, it transmits an alarm information message to a destination terminal and waits for a response of the destination terminal(S101). The MSC checks whether a lapse time after waiting for the response has exceeded a pre-set alarm information message re-transmission time(S103). If the lapse time has exceeded the pre-set alarm information message re-transmission time, the MSC checks whether the number of alarm information message transmissions so far has exceeded the pre-set number of alarm information message transmissions(S105). If the number of alarm information message transmissions so far has not exceeded the pre-set number of alarm information message transmissions, the MSC re-transmits the alarm information message to the destination terminal(S107). The MSC checks whether a response with respect to the call connection request has been transmitted from the destination terminal(S109). If the response has been transmitted, the MSC performs a procedure for call connection between the origination terminal and the destination terminal(S111).

It relates to a terminal.

Currently, in the call connection process of the CDMA mobile communication system, when the mobile communication system receives a call connection request from the calling mobile terminal, the paging signal is transmitted to the called mobile terminal to receive a response to the paging signal. An alert information message (CDMA network: Alerting Information Message) is transmitted to the mobile terminal.

When the called-party mobile communication terminal receives the alarm information message transmitted from the mobile communication system, the user operates a timer to count the waiting time for the call and sends an incoming call notification signal in any one of ring tone, vibration, or a combination thereof. Be aware of the incoming call.

If a signal for a call connection from the called user is not input to the called mobile terminal during the call waiting time (which is input through a key operation of the mobile communication terminal), the mobile terminal generates a call fade. To idle state.

On the other hand, the mobile communication terminal is equipped with a Qualcomm chip that includes a timer for determining the waiting time for the reception, the timer is set to drive the driving time of the timer to be driven in response to the alarm information message from the mobile communication system It is.

The call waiting time of the exchange in the mobile communication network can be set up to 127 seconds based on the Samsung CDMA-1X system, but the call waiting time is extended beyond the timer driving time set in Qualcomm due to the timer running time set in the mobile communication terminal. The problem arises.

As a result, because the incoming call waiting time of the called-party mobile communication terminal is limited, the receiving user often does not recognize the incoming call because of the short incoming call waiting time.

Waiting for a response of the first step; A second step of checking whether an elapsed time after waiting for a response exceeds a preset alarm information message resending time; And a third step of retransmitting the alarm information message to the called-party mobile communication terminal when the elapsed time after waiting for the response exceeds a preset alarm information message retransmission time as a result of the confirmation of the second step.

Another invention is a method for extending a call waiting time in a mobile communication terminal.

A first step of receiving, by the calling mobile communication terminal, a call connection, the mobile communication terminal receiving an alert information message transmitted from the mobile communication system; A second step of driving a timer for checking a call waiting time and generating an incoming call notification signal so that a user can recognize the incoming call; And a third step of resetting a timer by resetting a timer when receiving an alarm information message transmitted from the mobile communication system before a preset incoming waiting time elapses.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 1 is a diagram showing the configuration of a mobile communication system according to the present invention.

The mobile communication system (mobile communication network of FIG. 1) 200 is a base station in charge of wireless section communication with the mobile communication terminals 100 and 400, a base station controller for controlling a base station, and a switch exchanged with a base station controller to perform a call exchange. And a home location register, upon receiving a call connection request transmitted from the calling mobile terminal 100, an alert information message (eg, Alert with Information of the CDMA network) to the called mobile terminal 400. Message, WCDMA network alerting), and waits for a response from the called-party mobile communication terminal 400, the elapsed time after waiting for a response to reach the preset alert information message retransmission time, the called-party mobile communication terminal 400 If there is no response, the alarm information message is retransmitted to the called-party mobile communication terminal 400 through the base station.

Here, the elapsed time after waiting for a response is a time waiting for a response for a call connection request from the called mobile terminal 400 to be transmitted, and the preset alert information message resending time is sent to the called mobile terminal 400. This time is arbitrarily set to resend the alert information message within the range of not exceeding the set waiting time.

In addition, the mobile communication system checks whether the preset number of alarm information message transmissions has been exceeded before transmitting the alert information message to the called-party mobile communication terminal, and if it does not exceed the predetermined number of times, transmits the alarm information message. If the preset number is exceeded, a call connection failure message is transmitted to the calling mobile terminal 100.

2 is a view showing in detail the configuration of a mobile communication terminal according to the present invention.

Since the present invention is a technology applied to a mobile communication terminal when receiving, the reference number of FIG. 2 is to apply the reference number of the called mobile terminal, and the expression of the mobile communication terminal is not limited to the called mobile terminal. .

As illustrated, the mobile communication terminal 400 includes a control unit 410, an input unit 420, a memory 430, a wireless communication unit 440, an output unit 450, a call processing unit 460, and a timer driver 470. Incoming call notification unit 480.

Let's do it.

The call processing unit 460 communicates with the mobile communication system to perform a call connection procedure such as an origination or an incoming call.

When the timer driver 470 receives the alarm information message transmitted from the mobile communication system and transmitted via the call processor 460, the timer driver 470 drives a timer for checking the incoming call waiting time and moves before the incoming waiting time elapses. Upon receipt of the alert information message retransmitted from the communication system, the timer is reset to extend the call waiting time.

Here, the incoming call waiting time is a driving time of a timer set on the mobile communication terminal 400 and counts starting from the time when the alarm information message is received from the mobile communication system.

In addition, the alert information message retransmitted from the mobile communication system is transmitted from the mobile communication system according to the arbitrarily set alert information message retransmission time within a range not exceeding the incoming call waiting time set in the mobile communication terminal 400.

When the incoming notification unit 480 receives the alert information message transmitted from the mobile communication system and transmitted through the call processing unit 460, the user may recognize voice, vibration or the like through the output unit 450. The incoming call notification signal is sent in any one of these combinations.

As the exchange of the mobile communication system receives the call connection request transmitted from the calling mobile terminal 100, the call information is sent to the called-party mobile communication terminal 400 requested by the calling mobile terminal 100 to call. The message is transmitted and waits for a response from the called-party mobile communication terminal 400 (S101).

The exchange checks whether the elapsed time after waiting for response exceeds the preset alert information message resending time (S103). Here, the elapsed time after waiting for a response is a time waiting for a response for a call connection request from the called mobile terminal 400 to be transmitted, and the preset alert information message resending time is sent to the called mobile terminal 400. This time is arbitrarily set to resend the alert information message within the range of not exceeding the set waiting time.

As a result of the checking in step S103, when the elapsed time after waiting for response exceeds the preset alarm information message resending time, the exchange checks whether the number of alarm information message transmissions to date exceeds the preset alarm information message transmission number. (S105).

As a result of checking in step S105, when the number of times of sending the alert information message up to the present does not exceed the preset number of sending the alert information message, the exchange retransmits the alert information message to the called-party mobile communication terminal 400 (S107).

Thereafter, the exchange checks whether a response to the call connection request is transmitted from the called mobile terminal 400 (S109), and when the response is transmitted, the calling mobile terminal 100 and the called mobile terminal. Performs a procedure for the call connection between the 400 (S111). Here, the response to the call connection request is a message transmitted as the user of the called-party mobile communication terminal 400 operates (eg, selects a call button, etc.) for the actual call.

On the other hand, when the result of checking in step S109 is that a response is not transmitted from the called party's mobile communication terminal 400, the exchange performs the procedure after step S101.

On the other hand, if the check result of step S105, the number of transmission of the alarm information message to the present time exceeds the preset number of transmission of the alarm information message, the exchange may be delivered to the call connection failure notification message to the calling mobile terminal 100. The signal is transmitted to the corresponding configuration (configuration in the mobile communication system) so as to (S115).

On the other hand, when it is confirmed in step S103 that the elapsed time after waiting for response does not exceed the preset alarm information message retransmission time, whether the exchange has received a response to the call connection request from the called mobile communication terminal 400 Check whether or not (S113).

As a result of checking in step S113, when receiving a response to the call connection request from the called-party mobile communication terminal 400, the exchange for the call connection between the calling mobile communication terminal 100 and the called-party mobile communication terminal 400 Perform the procedure (S111).

As a result of checking in step S113, when the call response request is not received from the called-party mobile communication terminal 400, the exchange performs an operation after step S101.

First, the called-party mobile communication terminal 400 receives an alert information message transmitted from the mobile communication system as the calling mobile communication terminal 100 requests a call connection (S201).

Subsequently, the timer driver 470 of the called-party mobile communication terminal 400 drives a timer for checking the waiting time of the incoming call, and the incoming call notification unit 480 outputs 450 so that the user can recognize the incoming call. Through the transmission of the call notification signal in any one form of voice, vibration or a combination thereof (S203).

Thereafter, the timer driver 470 checks whether a preset call waiting time has elapsed (S205).

If the incoming call waiting time has not elapsed as a result of checking in step S205, the call processing unit 460 checks whether a response (entered through an operation of the mobile communication terminal 400) has been received by the user in response to the call connection request. (S207).

As a result of checking in step S207, if no response is received, the call processing unit 460 checks whether or not an alarm information message transmitted from the mobile communication system has been received (S209).

As a result of checking in step S209, when the alarm information message is received from the mobile communication system, the timer driver 470 resets the timer to initialize the call waiting time, and the call notification unit 480 receives the call through the output unit 450. The notification signal is transmitted (S213). Herein, the alert information message received from the mobile communication system is transmitted from the mobile communication system according to the arbitrarily set alert information message retransmission time within the range not exceeding the incoming call waiting time set in the called-party mobile communication terminal 400. Message.

On the other hand, when it is confirmed in step S209 that no alarm information message is received from the mobile communication system, the call processing unit 460 terminates the procedure for call connection.

On the other hand, when it is confirmed in step S207 that a response to the call connection is received from the user, the call processing unit 460 performs a call connection with the calling mobile terminal 100 (S211).

On the other hand, when the preset incoming call waiting time has elapsed as a result of checking in step S205, the call processing unit 460 terminates the procedure for call connection.
