The present invention provides an outgoing call information to the mobile communication method to overcome the impossible call situation of the mobile phone system, and provides an automatic answering function and a caller information service method that can leave the caller's voice message or phone number will be.

The mobile communication system is a system that can call a subscriber even if the subscriber moves to another place so that anytime, anywhere.

Accordingly, in order to call the mobile subscriber in the mobile telephone network currently being serviced, the caller calls the mobile subscriber through the wired telephone network or the mobile telephone network, and the call request is transferred to the corresponding calling party mobile telephone exchange and the home mobile telephone exchange After passing through the authentication process, the service is transferred to the called mobile telephone exchange. The terminating mobile telephone exchange pages the subscriber through the base station and, when the mobile subscriber responds, establishes the call path.

In order to call the mobile subscriber in such a mobile communication system, the call channel of the called party's mobile telephone exchange must be available while the subscriber terminal is powered on, and the mobile subscriber of the mobile subscriber can make a call of the mobile telephone exchange. It should be located in the radio environment where it can be received.

However, due to the characteristics of the mobile telephone network and battery consumption such as radio wave interference, radio wave arrival characteristics and limited frequency resources, there are factors that make it difficult for mobile subscribers to use the mobile telephone system more conveniently. Often times.

In other words, the current mobile telephone network often has a problem in that it is not possible to call the incoming mobile telephone due to the area where the phone cannot be called, the battery capacity of the terminal, the frequency shortage, and various other wireless communication problems.

The present invention has been made in order to solve the above problems when the mobile phone terminal is turned off to reduce power consumption, the mobile phone subscriber moves to the radio wave shadow area, or the call channel of the adjacent base station is insufficient. If the caller fails to call the mobile subscriber due to the situation, the mobile telephone exchange stores the telephone number, calling time, and other outgoing information in the database that the mobile subscriber did not receive and the mobile terminal is turned on. When the user checks the exchange database through the location registration or the location registration, he checks the outgoing call information that is not received and informs the subscriber of the mobile phone.In addition, the mobile telephone switcher switches the caller to the answering machine mode when the incoming call fails. Forward subscriber's voice message or caller's phone number Or leave a voice message, and the mobile telephone exchange receives the caller's response and automatically processes it, stores it in the voice mailbox inside the exchange, and then sends a voice mailbox message when the subscriber's terminal registers its location with the system. The purpose is to provide an information service method.

In order to achieve the above object, the present invention provides a method for calling service information applied to a mobile communication system, comprising: a first step of detecting outgoing call information not received by a mobile subscriber and storing it in a home mobile phone chess machine; And a second step (32 to 39) for providing outgoing information to the subscriber terminal when the subscriber terminal becomes available to call and requests location registration.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

Receiving the subscriber call request from the caller 11 (20), the incoming mobile telephone exchange 15 calls the incoming mobile subscriber 17 (21) to confirm the answer of the incoming mobile subscriber 17 (22). ). When the incoming mobile subscriber 17 responds, it allocates a call channel, constructs a call path, and ends (23).

However, if the terminal of the terminating mobile telephone subscriber 17 is powered off or the subscriber cannot answer due to a shortage of the terminating call channel, the terminating mobile telephone exchange 15 is called by the originating mobile telephone exchange 13. Notify that it is impossible (24). The outgoing mobile telephone exchange 13 notified of the unavailable call immediately switches to the answering machine mode (25) and sends the caller 11 a message indicating to leave a call unavailable message and a phone number or a voice message, and the subscriber answering message. If present, it waits for a certain time after forwarding it together (26). At this time, the outgoing mobile telephone exchange 13 automatically detects outgoing information such as the calling party's telephone number and outgoing time and stores it in the database of the home mobile telephone exchange 14 (27).

Subsequently, the calling mobile telephone exchange 13 checks whether the caller 11 has left a phone number or a voice message (28), if a voice message is left, and stores it temporarily (29), and then the home mobile telephone exchange 14 of the corresponding terminal. The home mobile telephone exchange 14 receiving the voice message is stored in the subscriber database and terminates (31). If there is no voice message, the caller 11 disconnects the call and checks whether the call is terminated.

On the other hand, when the subscriber station is in a callable state such as when the subscriber station is powered on and there is information stored in the database during the registration process with the home mobile telephone exchange 14 when the terminal requests a location registration, the subscriber receives the information stored in the database. Notify and later allow subscribers to directly retrieve their voicemail information. This process will be described in detail with reference to FIGS. 3 and 4.

3 is a flow chart of a subscriber call information providing process according to the present invention, the subscriber terminal can be turned on and receive the call information about the call attempts made to them in the course of receiving a message sent by the mobile telephone system.

When the subscriber station is powered on and receives a location registration request (32), the exchange 14 checks whether or not it subscribes to the calling information service (33) and if so, inquires an incoming call of the subscriber station (34) and returns the inquiry result. It is determined whether there is (35) and if there is outgoing information is called subscriber (36). Check if there is a response from the subscriber (37), if the subscriber responds by pressing the Send button, provide the outgoing information without notifying the subscriber (38) and terminate if the subscriber requests the call charge (39). In addition, if there is no subscription information service, no calling information or no subscriber response, the service is terminated immediately.
