Abstract

A method for confirming a reception state of a mobile terminal is provided to inform a user of an origination terminal about whether a destination terminal is connected with a system and a reception state of the destination terminal. When a receiving terminal(100) transmits reception unavailable state information to a base station(120), the base station(120) stores the reception unavailable state information of the reception terminal(305,307). When an origination terminal(150) attempts a call connection to the receiving terminal(100), the base station(120) accumulatively stores information of the origination terminal(150)(309,311). When the receiving terminal(100) is changed to a reception available state and transmits reception available state information to the base station(120), the base station(120) generates a call connection availability message and analyzes the stored information of the origination terminal(313,315,317). When call connections have been attempted more than a pre-set threshold times from the origination terminal(150), a call connection available message is transmitted to the origination terminal(150)(319).

The present invention relates to a method of notifying whether a reception is possible, and more particularly, to a service method of detecting a notification when a receiving terminal in a non-receiving state is switched to a receiving state and notifying the calling terminal.

Currently, the number of mobile terminal users is increasing rapidly. The increase in the number of users has led to the rapid development of the mobile communication field, and thus the users' desire for the quality of the mobile communication service is increasing. In order to satisfy the needs of the users, service providers provide various additional services.

The reception state of the conventional receiving side mobile communication terminal can be known only when the user of the calling side terminal communicates with the telephone number of the receiving side mobile communication terminal that the user wants to make a telephone call. At this time, if the receiving mobile terminal is busy according to the status of accessing the base station, the message 'Busy call' is provided, and if the receiving mobile terminal is turned off, the power is turned off. Message is provided, and if the receiving mobile communication terminal does not answer the phone, the message 'I am not answering the phone' is provided. You're in a region. ' In addition to providing the fragmentary message as described above, a voice mail service is simultaneously provided to notify the user of the calling terminal.

However, the conventional method of checking the reception state information of the receiving side mobile communication terminal has a problem of informing the calling terminal of the reception state information of the receiving side mobile communication terminal. In addition, since it is not possible to know when the receiving side mobile communication terminal accesses the system again, there is an inconvenience in that the user of the calling terminal must continuously try to redial to the receiving side mobile communication terminal.

Accordingly, an object of the present invention is to provide a service method capable of checking a reception state of a receiving mobile terminal.

In order to achieve the above object, the present invention provides a method of collecting and storing information of a receiving side and a calling terminal at a base station and providing the receiving state information of the receiving terminal to a calling terminal, wherein the receiving terminal is in an unreceivable state. Transmitting information to the base station, the base station storing unreceivable state information of the receiving terminal, and when the calling terminal attempts to make a call connection with the receiving receiving terminal, the base station transmits the calling side. Accumulating and storing information of the terminal; and when the receiving terminal is converted into a receivable state and transmits receiveable state information to the base station, the base station generates a call connectable message and stores the information of the stored calling terminal. Analyzing process, and as a result of the analysis, call connection more than the threshold number of times from the calling terminal When it characterized by the step of transmitting the call connection message to the calling terminal available.
