The present invention relates to a method for providing an additional service in an asynchronous IMT-2000 network. More particularly, when a called party is in an unreachable state, the caller receives a caller's reply request number and writes it in a short message. The present invention relates to an asynchronous IMT-2000 system having an outgoing call memo function for notifying an incoming call when the call is switched and a call out call memo service method.

With the high penetration rate of wired and wireless terminals, subscribers can try to make calls with the desired party anytime and anywhere, and can conveniently use various services such as using voice services as well as data services such as wireless Internet using mobile terminals. It became.

As one of various additional services of the mobile communication system, an outgoing number display service is provided to solve various problems due to anonymity of an incoming call (playing, obscene, violent calls, etc.). However, when the incoming call is not available, such as when the terminal is initialized, when the terminal is turned off, or when it is located in a shadowed area, the incoming call number of the incoming call is not notified to the subscriber even if the terminal is switched to a callable state. It was pointed out as a limit. In addition, if the called party deliberately rejects the caller, the caller may want to reply to another number later. In this case, the caller may not reply to the desired number because the caller only knows the calling number displayed on the terminal. .

In order to solve this problem, the terminal stores the incoming call history and the caller's reply request number when the call is in an unreachable state, and when the terminal switches to the callable state, a service for transmitting a call list including the callback request number to the terminal is called. This is a service limited to a synchronous mobile communication system, and there is a problem in that such a service cannot be provided in an asynchronous IMT-2000 network.

The asynchronous IMT-2000 network has the advantages of easy global roaming, excellent service quality between terminals and high frequency efficiency compared to the synchronous mobile communication system, and the asynchronous method is adopted in more than 80% of countries worldwide. In the countries that adopt the method, the asynchronous mobile communication service is gradually being introduced.

The present invention has been made to solve the above-mentioned problems, when a call is received by a terminal that can not be received in the asynchronous IMT-2000 network to receive the caller's return request number to write in short, and the terminal is in the callable state There is a technical problem to provide an asynchronous IMT-2000 system having a calling number memo function and a calling number memo service method for transmitting the incoming call list to the terminal.

In order to apply the calling number memo service according to the present invention, the called terminal is preferably a terminal capable of receiving a short message (SMS). When a call is attempted when the mobile communication terminal is in an unreachable state, the asynchronous IMT-2000 network of the present invention writes the caller's reply request number in a short message, and transmits the incoming call list when the called terminal switches to the callable state.

The called party can recognize the details of the incoming call when the terminal is in an unreachable state, such as when the terminal is in a call, when the terminal is powered off, initialized, or in a shaded area, and intentional rejection, and the subscriber who attempts to make a call to the called party later A response from the called party can be expected, which can improve the quality of service. Moreover, since these services can be serviced in an asynchronous IMT-2000 network, it is possible to provide a higher quality service to subscribers.

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

1 is a block diagram of an asynchronous IMT-2000 network according to the present invention.

As shown, the asynchronous IMT-2000 network (WCDMA system) is for controlling the Node B 20 and the Node B 20 as a base station for wireless section communication with the mobile communication terminals 10-1 to 10-n. Radio Network Controller (RNC) 30, Mobile Switching Center (MSC, 40) connected to one or more Radio Network Controllers (30) for call exchange, subscriber information management and additional service availability and status, etc. Home Location Register (HLR) for managing the (HLR, 50), intelligent network service controller (Service Control Point; SCP, 60) for storing and managing the control information and subscriber data for intelligent network services and the wireless network controller (30) and Based on IP, a data service node (SGSN, 70) for monitoring the location of mobile communication terminals 10-1 to 10-n and performing security functions and access control functions connected to IP networks. SGSN (70) over one packet domain PLMN backbone network Gateway GPRS Support Node (GGSN, 80), a comprehensive customer information center that manages customer management, billing, billing, and payment of payments through a customer-oriented information system that is designed, built, and operated in a mobile communication system. Customer Oriented Information System (COIS, 90), a basic short-term service center (SMSC) 110 for transmitting a limited size of text between mobile communication terminals or between a mobile communication terminal and a mobile communication network.

In addition, the asynchronous IMT-2000 network of the present invention further includes a Call Receipt Service (Cellular Recall Service; 'CRS') server 100, when the destination terminal is in a call-free state, from the home location register 50 It is connected to the calling mobile communication terminal through the exchange 40 that has received this fact, prompts the calling subscriber to enter a reply request number and sends it to the SMSC 110, and when the called terminal switches to a callable state, the SMSC 110 ) Transmits the stored call history to the called terminal.

In addition, the home location register 50 of the present invention activates the additional service field in the information field of the subscriber, if the mobile communication service subscriber requests registration of various additional services (calling number memo service, etc.) through the COIS (90) do. Registration of the additional service may be applied through the wired or wireless Internet as well as the COIS 90. In addition, the home location register 50 transmits the service control information to the exchange when registering the location of the subscriber to notify the home location register 50 when an event that satisfies the corresponding service control information occurs during call setup of the exchange period. As such, when the exchange transmits the service control request signal to the home location register 50, it is preferable to transmit the cause of the service control request.

That is, the home location register 50 transmits control information for requesting the service control request to the home location register 50 when the terminal is in an unreceivable state to the exchange when registering the location of the subscriber, and the calling subscriber attempts to make a call. If the status of the terminal at the destination exchange meets the control information requested by the home location register 50 after the call is established in the exchange and the destination exchange period, that is, when the destination terminal is in an unreceivable state, the exchange is in a state in which the destination terminal cannot be received And a service control request message including information on the reason and the reason (during call, no answer, rejection, etc.) to the home location register 50.

Receiving such a service control request message, the home location register (50) transmits the routing information to the called party note service server (100) and the announcement broadcast code for notifying the reason for the reception to the called party exchange to the called party exchange and the calling party number memo. Call setting is made between the service servers 100.

On the other hand, when the caller attempts to make a call and the home location register 50 requests routing information to the destination exchange, when the destination terminal is determined to be in a power-off state, the home location register 50 determines whether the called party is a caller ID memo service user. If the user checks the calling number memo service, the call setting is transmitted between the calling exchange number and the calling number memo service server 100 by transmitting the routing information to the calling number memo service server and an announcement code indicating the reason for the reception. To be done.

In addition, the exchange 40 of the present invention receives and stores the additional service information of the subscriber and the service control information for requesting service control when the subscriber does not receive the service from the home location register when registering the location of the subscriber, and the calling party and the called party. If the called subscriber station is determined to be unreceivable after a call is established between the exchanges, that is, if the service control information received from the home location register 50 is satisfied, the called subscriber terminal is not called and the reason is indicated. To send).

The unreachable state of the mobile communication terminals 10-1 to 10-n includes a case where a call is in progress, when the power is turned off, when it is being initialized, when it is located in a shaded area, and when it is deliberately rejected. When the mobile communication terminals 10-1 to 10-n transition to a receivable state, the mobile communication terminal performs location registration again in association with the switch 40 and the home location register 50.

2 is a flowchart illustrating a subscriber location registration procedure in an asynchronous IMT-2000 network.

When a situation in which the mobile communication terminal (MS) needs to perform location registration occurs, the mobile communication terminal requests the location registration to the exchange (S101), the exchange requests it to the home location register (S102), and the home location register is the exchanger. The subscriber's profile information is transmitted in step S103. At this time, the service control information is transmitted to the exchange, and if the state of the terminal satisfies the service control information during call setup, the exchange transmits the service control request message to the home location register. That is, when the terminal is in a non-receivable state, service control information for notifying the home location registrar is transmitted to the exchange. The service control request message is included.

Thereafter, when the exchange transmits a response signal for the profile of the subscriber to the home location register (S104), the home location register performs location registration through an authentication process and transmits the result to the exchange (S105). The location registration result is transmitted to the terminal (S106).

3 is a flowchart illustrating a caller ID memo service method in an asynchronous IMT-2000 network according to an embodiment of the present invention. When the called terminal is busy, when the called terminal does not answer, the called subscriber deliberately In case of rejecting the reception, it indicates the caller ID memo service method. In order to apply the present embodiment, it is preferable that the called terminal is a terminal capable of receiving a short message. Hereinafter, for convenience of description, the mobile terminal will be divided into a called terminal MS _T and a calling terminal MS _O which have transitioned to a non-receivable state.

In the present embodiment, when the called terminal is busy, when the called terminal does not answer, or when the called subscriber intentionally refuses to receive, the receiving terminal is in the state described in FIG. Location registration has been performed. In this state, when the call is attempted together with the calling number and the called number from the calling subscriber terminal (MS _O ) (S201), the calling side exchange (MSC _O ) checks the calling party information and then dials the calling party to the (called party) home location register. Requests the called party information together with the called number (MAP_SRI; MAP_Send Routing Information) (S202).

The home location register extracts the called terminal number by referring to the message (MAP_SRI) received from the calling exchange (MSC _O ), checks the exchange where the called party is roaming, and requests routing to the called exchange (MSC _T ) ( MAP_Provide Roaming Number) (S203). The destination exchange (MSC _T ) transmits routing information to the home location register as a response message (MAP_Provide Roaming Number) received from the home location register (MAP_Provide Roaming Number Ack) (S204), and the home location register is the calling party. The receiver routing information is transmitted to the exchange MSC _O as a response signal to the receiver information request (MAP_SRI_ack [IMSI _T , MSRN]) (S205). Here, the response message (MAP_Provide Roaming Number Ack) for the routing request includes the roaming number (RoamingNum = MSRN) of the called terminal, and the called party information transmitted to the calling exchange (MSC _O ) includes the called terminal identifier and the roaming number. Include.

Then, the caller-side switching center (MSC _O) a receiver-side switching center (MSC _T) as there is to be a call set up by transmitting a calling number and called number (S206), receiver-side switching center (MSC _T) is a home location register in a location registration process ( When the called terminal MS _T satisfies the service control condition according to the service control information received from 50), that is, whether the called terminal MS _T is available for incoming call and the call is impossible, the home terminal register corresponds to the called terminal ( The service control request message (InitialDP) including the reception state and the reason for the MS _T ) is transmitted (S207).

The home location register receiving the service control request message transmits the routing information to the called number memo service server and the announcement code indicating the reason for the reception to the called side exchange (MSC _T ) (S208). The destination exchange (MSC _T ) transmits the calling number, the called number, etc. to the calling number memo service server 100 based on the routing information received from the home location register, and sets up the call (S209). _O ) and the call is set between the caller ID number service server 100 (S210). Calling number memo service server 100 to enter the request number of the reply to the calling terminal (MS _O ) and transmits it to the SMSC (110) to send to the called terminal (MS _T ) (S211). Since the SMS transmission procedure is a general process, a detailed description thereof will be omitted.

In this embodiment, it is also possible to allow the caller to enter a voice message in addition to entering a reply request number. When the voice message is received and stored, the caller's message is transmitted to the called terminal through the voice message service center (VMS).

4 is a flowchart illustrating a caller ID memo service method in an asynchronous IMT-2000 network according to another embodiment of the present invention, and shows a case where the terminating terminal is powered off. In order to apply the present embodiment, it is preferable that the called terminal is a terminal capable of receiving a short message. Hereinafter, for convenience of description, the mobile communication terminal will be described by dividing it into a calling terminal MS _O and a called terminal MS _T transitioned to an unreceivable state.

In the present embodiment, the called terminal is powered off and must be in a state where location registration is performed by the procedure described in FIG. 2 before the power is turned off. When the call is attempted together with the calling number and the called number from the calling subscriber terminal (MS _O ) (S301), the calling side exchange (MSC _O ) checks the calling party information and then dials the calling number and called number to the home address register. Request the called party information together (MAP_SRI; MAP_Send Routing Information) (S302).

The home location register extracts the called terminal number by referring to the message (MAP_SRI) received from the calling exchange (MSC _O ), checks the exchange where the called party is roaming, and requests routing to the called exchange (MSC _T ) ( The MAP_Provide Roaming Number (S303) and the destination exchange (MSC _T ) transmit a response message for the message received from the home location register (MAP_Provide Roaming Number) to the home location register (MAP_Provide Roaming Number Ack) (S304). Since the exchange MSC _T knows that the terminal is powered off, in step S304, the destination side MSC _T is turned off when the response message to the routing information request is sent to the home location register. Notify that there is.

The home location register that receives the power-off state of the called terminal from the called terminal exchange (MSC _T ) checks whether the called party is a calling party memo service subscriber (S305), and if it is a calling party memo service subscriber, the calling party exchange (MSC _O). In response to the request of the called party information), the routing information including the routing information to the caller's number memo service server and a reason for not receiving is transmitted.

The calling side exchange (MSC _O ) transmits the calling number, the called number, and the like to the calling number memo service server 100 based on the routing information received from the home location register, and establishes a call (S307). Accordingly, the calling terminal (MS) _O ) and the call is set up between the caller number memo service server (100) (S308). Calling number memo service server 100 to enter the request number of the reply to the calling terminal (MS _O ) and transmits it to the SMSC (110) to transmit to the called terminal (MS _T ) (S309). Since the SMS transmission procedure is a general process, a detailed description thereof will be omitted.

In this embodiment, it is also possible to allow the caller to enter a voice message in addition to entering a reply request number. When the voice message is received and stored, the caller's message is transmitted to the called terminal through the voice message service center (VMS).

According to the present invention, when the called terminal is incapable of receiving an incoming call, the details of the incoming call are stored in the corresponding terminal according to the reason for not being able to receive the call. You can prevent it from being delivered.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive.
