BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, and more particularly, to a method for providing called party information in a mobile communication network to notify a caller periodically / real time of current status information of a called party using an existing mobile communication network.

In general, there is no way to know the status of a terminal called in a mobile communication system without dialing the terminal. If the caller dials the called terminal, the exchange checks the state of the called terminal and displays the state of the called terminal (eg, power-off, busy, no answer). The caller is informed using a voice message. Even in the case of additional services such as call forwarding, the caller cannot know the state of the called terminal.

In another aspect of the mobile communication system, even if the sender has sent a Short Message Service (hereinafter abbreviated as SMS) message, the sender has determined that the SMS message was successfully delivered to the destination, delivered, or opened. I do not know whether or not. Even when the called terminal is in the SMS message rejection state, the caller sends the SMS message in vain. Moreover, when the caller sets his terminal to various states such as 'recipient rejection', 'in a meeting', 'transfer', 'driving', etc., the user should dial the other terminal only after the other party dials the terminal. You can assume that you are in a situation where you cannot receive.

In the case of the conventional voice call service, the caller can obtain information such as call forwarding, call forwarding (power-off), and busy by the ARS voice message from the network only after the caller makes a call.

In the case of the conventional short message transmission service, the sender cannot know whether the SMS message has arrived at the called terminal. Depending on the structure of the calling terminal, the caller knows if the caller receives the SMS message when the caller sends the SMS message or if the SMS message has arrived at the SMS center if the calling terminal is in a power-off state. Would want to.

Therefore, the above-mentioned services have a problem in that the called party has no way of informing the caller (caller) of his current incoming state such as 'reject', 'in a meeting', 'transfer', or 'in operation'.

The present invention was devised to solve the above problems, and an object of the present invention is to move the caller to notify the caller periodically / in real time of the caller's current situation while the caller performs the call operation. The present invention provides a method of providing called party information in a communication network.

A method for providing called party information in a mobile communication network according to the present invention for achieving the above object comprises the steps of: a) inputting a current state registration information of a called party through a messenger service system, and then transmitting to a gateway through an internet network; b) requesting, by the MSC (Mobile Switching Center), the called party's location information to the called party's Home Location Register (HLR) according to the calling establishment request; c) transmitting, by the called party's home location register (HLR), a nickname service triggering message to a called party identification server; d) querying the gateway for nickname information by the called party identification server and receiving a response accordingly; e) after the called party identification server receives the nickname information from the gateway, transmitting the nickname information to the called party's home location register (HLR); f) transmitting, by the called party's home location register (HLR), the nickname information in a predetermined field to the mobile switching center (MSC); g) the mobile switching center (MSC) reflecting the nickname information of the predetermined field in a predetermined display field and transmitting the same to the calling terminal.

Therefore, according to the present invention, it is possible to meet the desire of consumers to express themselves by enabling the recipient to transmit the status information (nickname, location information, etc.) of the called party to the caller at the time of the call attempt without changing the exchange or other existing network nodes. .

Subsequently, the gateway 7 which has been queried for the status information of the called party from the called party identification server 6 responds to the called party's status information received from the called party status information registration server 8 periodically / in real time. The called party identification server 6 transmits the status information to the called party HLR 5 and responds to the service triggering message of the called party HLR 5.

Subsequently, a process of transmitting and displaying the called party's status information to the calling terminal 1 will be described in detail in the operation flowchart of FIG. 2.

2 is a flowchart illustrating a method for providing called party information according to the present invention.

As shown in the drawing, the method for providing called party information comprises the steps of: a caller and a called party joining the called party state information registration server on the Internet; Transmitting the current status information registered by the called party to the gateway through an internet network; Requesting the call establishment by the caller; Requesting, by the MSC, location information of the called party to the called party's HLR according to the caller's call establishment request; Transmitting, by the called party's HLR, a nickname service triggering message to a called party identification server; The called party identification server querying the gateway for nickname information, and receiving a response accordingly; After the called party identification server receives the nickname information from the gateway, sending a response to the service triggering message to the called party HLR; Receiving, by the called-side HLR, a response to the service triggering message, and sending it to the MSC by putting it in a predetermined field; Transmitting, by the MSC, the nickname information of the predetermined field to a calling terminal by reflecting the nickname information in a predetermined display field; And displaying, by the calling terminal, the nickname information reflected in the predetermined display field on a screen.

Hereinafter, a series of operations according to the called party information providing method configured as described above will be described.

First, the caller and the receiver who want to receive the caller status information providing service subscribe to the caller status information registration server 8 of the messenger service provider on the Internet (S201). At this time, when the called party registers, his or her nickname (Nickname) is registered in the called party status information registration server 8, where the nickname is not limited to the called party's nickname, but various information such as the current called party's status information. It can be information. In addition, the called party registers the nickname indicative of his or her current state not only at the time of initial registration but also periodically / in real time.

When the messenger service subscriber registers the nickname information at the time of registration, or updates and registers periodically / in real time (nickname information update), the called party status information registration server 8 of the messenger service provider is a called party ( That is, the subscriber's current state information registered by the subscriber is transmitted periodically / in real time to the gateway 7 through the Internet network (S202).

As described above, while the called party registers his / her current state information periodically / in real time, the caller calls the called terminal 2 through the calling terminal 1 to make a call to the called party in the mobile communication network. Request the setting (S203).

Thereafter, the MSC 3 requests the called party's location information to the called party's HLR 5 according to the call setup request of the calling party (S204).

Subsequently, the called party's HLR 5 determines whether the called party is the messenger service subscriber by referring to the called party's telephone number. When the called party is the messenger service subscriber, the called party calls the call corresponding to the called party. The service triggering message is transmitted by handing over to the confirmation server 6 (S205).

The called party identification server 6 maps email addresses corresponding to the called party's telephone numbers, respectively, so as to query the gateway 7 for nickname information (called state information of the called party) corresponding to the called party's email address (S206). In step S207, a corresponding response is received from the gateway 7.

The called party identification server 6 receives the nickname information from the gateway 7 and then sends a response to the service triggering message to the called party HLR 5.

Subsequently, after receiving the response to the service triggering message, that is, the nickname information, the called party HLR 5 places the nickname information in the display text field of the Locreq Return Result, which is a map message. The data is transmitted to the MSC 3 (S209).

Steps S209-1 and S209-2 are further methods for transferring the nickname information to the MSC 3, which will be described.

First, in step S209-1, the called party's HLR 5 receives the nickname information and does not use a display text field of a Locreq Return Result, which is a map message, and corresponds to the nickname information. The nickname information is loaded in a display text field of an information directive, which is another map message, and transmitted to the MSC 3.

As another method, in step S209-2, the called party identification server 6 receives the nickname information from the gateway 7, and then directly sends an information directive message, which is a map message corresponding to the nickname information, to the MSC ( 3) to send.

Thereafter, the MSC 3 reflects the nickname information of the display text field to the display field of the feature notification and transmits the nickname information to the calling terminal 1 (S210).

If, as in step S209-1, the called party identification server 6 directly transmits an Information Directive message, which is a map message corresponding to the nickname information, to the MSC 3, the MSC 3 sends the message. An Information Directive message is directly transmitted to the calling terminal 1.

Thereafter, the calling terminal 1 displays the nickname information reflected in the display field of the Feature Notification on the screen for confirmation of the user (S211). Here, the display method of the nickname information, that is, the status information of the called party may be variously performed according to the status information, and may use a known display technique.

Therefore, the caller can check the current state information of the other party (called party) to make a call through the screen window of the terminal during the call operation.

As described above in detail, a method of providing called party information in a mobile communication network according to the present invention may be provided as various types of data services in connection with a service provider.

In addition, the method of providing called party information in the mobile communication network according to the present invention can use the existing network and the service of the existing messenger service company, so that the user can reduce the cost burden.

In addition, in the mobile communication network according to the present invention, the method of providing called party information includes a consumer who wants to express himself or herself by allowing the called party to transmit the status information (nickname, location information, etc.) of the called party to the caller during a call attempt without changing the exchange or other existing network nodes. Can meet their needs.

In addition, in the mobile communication network according to the present invention, the method of providing the called party information can be induced to inform the other party of the called party in advance so that the caller can avoid the general call, so that the terminal is adaptively adapted to various state changes of the called party. Can be operated.
