The present invention can be applied to both a mobile communication subscriber and a general public switched telephone network through a mobile communication system to both landline telephone subscribers. However, the following description focuses on mobile subscribers.

1 is a diagram illustrating a system configuration of a mobile communication system to which the present invention is applied.

Referring to Figure 1 below, first, the mobile communication system is connected to the public telephone switching network (109) and the mobile phone switching center (Mobile Switching Center: 107) for connecting a call with a landline telephone and a mobile communication terminal period, A base transceiver subsystem (103) and a base station controller (105) connected to the mobile switching center (107) to control the plurality of base stations (103). The public switched telephone network 109 may be connected to a plurality of mobile communication systems.

An operation of the call connection notification service according to the present invention in the communication system having the above configuration will be described. There may be two cases of call connection notification according to the present invention. The first is when the receiver is a landline subscriber, and the second is when the receiver is the same mobile terminal. First, in the description of the first case, a case in which the mobile communication terminal 101 makes a call to the landline phone 119 will be described. When the mobile communication terminal 101 attempts to make a call by inputting the telephone number of the landline telephone 119, the mobile station 101 transmits an outgoing message. The outgoing message is received at base station 103 and input via mobile station controller 105 to mobile switching center 107. Upon receiving the outgoing message, the mobile switching center 107 analyzes the outgoing message, detects a telephone number, generates and outputs a dial tone. At this time, the PSTN 109 receives the dial tone generated by the mobile switching center 107, connects to the corresponding landline 119, and sends out a ring tone. At this time, the mobile communication terminal 101 listens to the ringtone through the mobile switching center 107, the base station controller 105, and the base station 103 as ringback tones. While the mobile communication terminal 101 is listening to the ringback tone, the mobile switching center 107 continuously checks through the PSTN 109 whether the landline 119 responds to the ringtone. At this time, when the landline 119 responds to the ring tone, the mobile switching center 107 detects this, generates a call connection notification message, and transmits the message to the mobile communication terminal 101 through the base station controller 105 and the base station 103. At this time, the mobile communication terminal 101 receives the call connection notification message and generates an alarm such as an alarm sound, a vibration, or a melody.

In the second case, a case where the mobile communication terminal 101 makes a call to the mobile communication terminal 117 or the mobile communication terminal 119 will be described.

When the mobile communication terminal 101 attempts to make a call by inputting the telephone number of the landline telephone 119, the mobile station 101 transmits an outgoing message. The outgoing message is received at base station 103 and input via mobile station controller 105 to mobile switching center 107. Upon receiving the outgoing message, the mobile switching center 107 analyzes the outgoing message, detects a telephone number, and transmits a paging signal, which is a paging signal, to the mobile communication terminal 117 or 119 through the base station controller and the base station. At this time, the mobile communication terminal 101 listens to the ringback tone as the first time until the mobile communication terminal 117 or 119 presses a call key. The mobile switching center 107 checks whether a call response message is received from the mobile communication terminal 117 or 119 while the ring back tone is ringing. When the call response message is received from the mobile communication terminal 117 or 119 during the inspection, the mobile switching center 107 transmits the call connection notification message through the base station controller 105 and the base station 103. The mobile communication terminal 101 receives the call connection notification message and generates an alarm.

2 is a diagram illustrating a configuration of a mobile communication terminal to which the present invention is applied. FIG. 4 is a flowchart illustrating a call connection notification service method in a mobile communication terminal of a mobile communication system according to an embodiment of the present invention. Hereinafter, the configuration and operation of the mobile communication terminal according to the present invention will be described in detail with reference to FIGS. 2 and 4.

First, the configuration, the controller 10 controls the overall operation of the mobile communication terminal. The memory 20 includes a ROM for storing a predetermined operating program, a RAM for temporarily storing data generated during the execution of the operating program, and an electrically programmable EEPROM. The alarm unit 30 generates alarm sound, vibration, and melody under the control of the controller 10. The duplexer 70 separates a radio signal received through an antenna and a radio signal transmitted. The message processor 60 analyzes the message received from the base station 105 and generates a transmission message. The transmitter 40 converts a message input from the message processor 60 into a radio signal under the control of the controller 10 and transmits the message to the base station 105 through the duplexer 70 and the antenna. Under the control of the controller 10, the receiver 50 converts a radio signal received through the duplexer 70 into a digital message and outputs the message to the message processor 60.

Referring to FIG. 4, the controller 10 checks whether a call is attempted by inputting a telephone number and a call key from a key input unit (not shown) in step 401. When the mobile communication subscriber inputs a call key, the controller 10 detects in step 401 and proceeds to step 403. The controller 10 transmits an outgoing message to the base station 103 in step 402, and then proceeds to step 403 to receive a ringback tone through a paging channel and output it through a speaker (not shown). The controller 10 proceeds to step 407 while outputting the ringback tone to check whether a call connection notification message is received from the base station 105. In this case, when the call connection notification message is received from the base station 105, the controller 10 proceeds to step 408 and outputs an alarm sound, vibration, or melody through the alarm unit 30. After the alarm is generated, the controller 10 proceeds to step 409 and checks whether a channel assignment message is received. If the channel assignment message is received, the controller 10 proceeds to step 410 to form a call path and starts a call.

The call connection notification message may be included in the channel assignment message of step 409 and received. When received in the channel assignment message, the controller 10 detects a call connection notification message from the received channel assignment message, generates an alert, and simultaneously forms a call path.

2 and 4 illustrate the configuration and operation of the mobile communication terminal. Hereinafter, the configuration and operation of the mobile exchange will be described with reference to FIGS. 3 and 5. 3 is a diagram illustrating a configuration of a mobile switching system to which the present invention is applied, FIG. 5 is a flowchart illustrating a call connection notification service method in a mobile switching system, and FIG. 6 is a mobile communication system according to another embodiment of the present invention. Is a flowchart illustrating a call connection notification service method in a mobile switching center.

Referring first to the configuration of the mobile switching center 107 according to the present invention with reference to FIG. 3, the controller 127 controls the overall operation of the mobile switching station. The memory 129 stores a predetermined program for controlling the overall operation of the mobile switching center, and temporarily stores data generated in the program execution week. The message processor 128 generates a message to be transmitted, analyzes the received message, and outputs the received message to the controller 127. The BSC connection unit 121 is connected to a plurality of base station controllers (BSC) to interface signals transmitted and received to the base station controllers. The network connection unit 125 is connected to a network such as a general public telephone network (PSTN) 109 or ISDN to interface a signal transmitted and received to the public telephone network or ISDN network. The switching unit 120 switches the signals input and output through the BSC connection unit 121 and the network connection unit 125 under the control of the controller 127. The call connection detection unit 123 is connected to the network connection unit 125 to detect whether a call is connected when a call is connected to another network.

The operation according to the present invention of the mobile switching center having the above-described configuration will be described with reference to FIG. 5, where the mobile communication terminal 101 makes a call to the mobile communication terminal 119, and the telephone line 117 is called. The case of hanging will be explained using an example.

First, a case of making a call to the mobile communication terminal 101 will be described first. In step 501, the controller 127 checks whether an outgoing message is received. In this case, when an outgoing message is received from the mobile communication terminal 101, the controller 127 analyzes the outgoing message through the message processor 128 in step 502, detects a phone number, and controls the switching unit 120 in step 503. The mobile station 119 transmits a call message to the mobile communication terminal 119 through the base station controller 105 and the base station 103. The controller 127 proceeds to step 507 after transmitting the call message and checks whether a call response message is received from the mobile communication terminal 119. If the call response message is received from the mobile communication terminal 119 during the inspection, the controller 127 proceeds to step 508 and transmits a call connection message to the mobile communication terminal 101 which is the caller. Send a call to form a call path in step 510. The call connection message may be transmitted before the channel assignment message is transmitted as described above, or may be inserted into the channel assignment message and transmitted. If the call response message is not received in step 507, the process proceeds to step 511 to perform a general call processing process.

Hereinafter, when the mobile communication terminal 101 makes a call to the general wired telephone 119, the controller 127 may perform steps 503 to 603 corresponding to steps 503 to 503 and 511 to 511, respectively. Steps 608 and 611 are performed in the same manner. However, the controller 127 receives the call response message of step 507 from step 607 and transmits the call connection message instead of receiving the call connection message, and receives the call connection signal detected and input by the call connection detection unit 123. Transmit to 101.

As described above, the present invention has the advantage that the caller can lift the communication terminal when an alarm occurs while the other person does not need to hold the communication terminal continuously until the call path is formed.
