Description

System and method for providing unreceived call history service in mobile communication network, and server for providing unreceived call history service for realizing it {METHOD AND SYSTEM FOR PROVIDING CALLING NUMBER HISTORY PRESENTATION Service

The present invention relates to a technology for serving a user with an unreceived call log in a mobile communication network, and in particular, an unreceived call log providing service can accurately notify a user in the form of a short message to increase the satisfaction of a service subscriber. The present invention relates to an unreceived call log providing service system and method in a mobile communication network, and an unreceived call log providing service server for implementing the same.

Due to technological advances in the field of mobile communication services, various types of services are provided to clients, including, but not limited to, basic mobile communication services such as voice call service, voice mailbox service, and short message service. have.

Among them, when the called terminal is not connected due to busy, power off, no answer (NA), no page response (NPR), etc., a service that notifies the client in the form of a short message of the received call history (Unreceived call history service) is commercially available.

4 illustrates a call processing process when a called party is establishing a call in such an unreceived call history providing service.

As shown in FIG. 4, during a general call setup procedure between the originating exchange 10a and the destination exchange 10b, it is determined whether a second call setup is requested to the incoming exchange 10b in a call (S400).

When a call establishment request for the busy state of the destination exchanger 10b is received, the call waiting processing is performed at the destination exchanger 10b even if the called subscriber is using a Call Waiting service (CW service). It becomes impossible (S402) (S404).

Accordingly, the called exchange 10b determines that the called subscriber is in a busy state, and transmits busy state information to the called home location register (HLR) 12b (S406). At this time, the retransmission reason is set to "Redirection Reason = Busy".

The incoming home location register 12b receiving the busy state information transmits the service information to the unreceived call log providing service server 14 (S408). That is, it is determined whether the called party recognizes that the unreceived call log providing service is activated, and transmits service information, for example, "SevInfoDirective" to the unreceived call log providing service server 14. In this case, the service information may include "unreceived call history providing service, Redirection Reason = Busy".

Then, the incoming call history providing service server 14, as shown in step S410, the unreceived call history providing service phrases including the calling number, for example, "unreceived call history-busy" along with the calling number Send to the called party.

Such an unreceived call log providing service preferentially handles the call waiting service when the called subscriber is using the call waiting service while the call is busy, so that the unreceived call log providing service does not operate.

However, since the call waiting service can operate only when the calling party and the called party are normally connected and making a call, a call collision occurs because the calling party tries to call each other to establish a call. In this case, the call waiting service does not operate.

In this situation, if the called party is using an unreceived call log service, the service operates to inform the called subscriber that there is an unreceived call during the call, and the called party already uses the waiting call service as well. Therefore, when the short message is received that there is an unreceived call during the call, it is determined that the call waiting service is not operating normally. In other words, if the call waiting service is operated normally, the call waiting state should be waited for in the call waiting state, but the receiving subscriber will receive a short message that there is an unreceived call during the call. Is determined to be operating abnormally.

In more detail, the unlisted call history providing service and the call waiting service are simultaneously used. If a subscriber attempts to reach the subscriber by a third party (or the called party of the call) while setting up an outgoing call, the subscriber is busy. Since the standby service cannot operate and the destination exchange sends a busy message to the HLR, the HLR operates the unreceived call history providing service to indicate that the subscriber has been busy with the unreceived call history providing service server. In addition, the unreceived call history providing service server sends a short message to the subscriber, for example, the message "unreceived call history providing service-busy", so that the subscriber may be mistaken as if the call waiting service does not work. will be.

Accordingly, the present invention, when the busy state due to a call collision, not a normal call state and the unreceived call history providing service is provided (the call waiting service is inoperable), the call waiting service to the called subscriber is operating normally The present invention provides a system and method for providing an unreceived call log service in a mobile communication network which can be notified by a message and recognize a more accurate service situation, and an unreceived call log service server for implementing the same.

According to an aspect of the present invention, a mobile client group receiving an unreceived call history providing service through a mobile communication network, and determining whether the incoming mobile client of the mobile client group is a user who is subscribed to a call waiting service. Information that can be stored, and a home location register that provides information on the unreceived call log service and information on the call waiting service, and provides a short message service environment within the mobile client group according to the determination result. A short message service center for transmitting the provided service text and / or the short message information during the call connection to the called mobile client; and if the unreceived call history providing service information is transmitted from the home location register, the short message service text is received. Service center In the case where the unreceived call history providing service information and the call waiting service information are transmitted from the home location register, the phrase informing the activation of the unreceived call history providing service and the call waiting service in connection with the short message service center is a short message form. The present invention provides an unreceived call log providing service system in a mobile communication network including an unreceived call log providing service server transmitted to the called mobile client.

According to another aspect for solving the problems of the present invention, a mobile communication terminal provided with an unreceived call history providing service associated with a short message service center, the call due to a busy state due to a call collision A management unit that determines whether the mobile communication terminal subscribes to the busy service when the mobile communication terminal is not available, and if the mobile communication terminal is subscribed to the busy service, the mobile communication terminal is busy using the short message service center. It provides an unreceived call history providing service server including a transmission unit for transmitting a phrase indicating that the standby service is in normal operation.

According to yet another aspect for solving the problems of the present invention, a call receiving service history service method in a mobile communication network when a called subscriber is busy during a call collision and the waiting service is inactive, the called subscriber When the second call setup is requested to the destination exchange of the first step of transmitting the busy state information to the destination home location register of the called party, and the destination subscriber is subscribed to the call waiting service in the destination home location register A second process of determining whether there is a call, and a third process of transmitting, in the form of a short message, a phrase informing the unsubscribed call log providing service phrase and the call waiting service activation to the called subscriber if the called subscriber is subscribed to the call waiting service. Providing an unreceived call history providing service method in a mobile communication network including a All.

According to the present invention, when a busy state due to a call collision is not a normal call state and an unreceived call log providing service is provided (a call waiting service is inoperative), the waiting call service is briefly operated by a called party. By notifying a message, more accurate service status can be recognized.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a schematic block diagram of an unreceived call history providing service system in a mobile communication network according to an aspect of the present invention, and includes a mobile client group 100, a mobile communication network 102, a home location register 104, and a short message. The message service center 106 and the unreceived call history providing service server 108 are included.

As shown in FIG. 1, the mobile client group 100 refers to mobile clients such as (or possess) mobile terminals, for example, cellular phones, PCS phones, DMB phones, video phone phones, and the like. Interface with the wireless connection 102 to provide a wireless communication service to the subscriber. The mobile client group 100 may support not only the second generation supporting the CDMA (Code Division Multiple Access) method, but also the wireless supporting the third generation or more mobile communication technology of the wideband code division multiple access (W-CDMA) method. Includes all of the environment

The mobile communication network 102 is involved in call setup and resource allocation of the mobile client group 100. Although not shown in the drawing, a mobile communication network involved in call setup and resource allocation of a second, different mobile client group may be established. It will be readily apparent to those of ordinary skill in the art.

The mobile communication network 102 serves to guarantee the mobility of the mobile client group 100 and performs handover and radio resource management functions. The mobile communication network 102 includes a base station and a base station controller, and supports both synchronous and asynchronous. Here, in the case of synchronous, the base station will be a base transceiver station (BTS), the base station controller will be a base station controller (BSC), in the case of asynchronous, the base station is a Node B (Node B), and the base station controller is a Radio Network Controller (RNC). Will be. Of course, the wireless communication network 200 is not limited thereto, and may include a GSM network other than a CDMA network and an access network of all mobile communication systems to be implemented in the future.

A base station having such an example configuration receives a call attempt message from the mobile client group 100 through a traffic channel among signal channels, and transmits the received call attempt message to the base station controller. In addition, the base station is a network endpoint device that is directly connected to the mobile client group 100 by performing baseband signal processing, wired and wireless conversion, and transmission and reception of wireless signals. The base station controller controls the base station, and assigns and releases radio channels to the mobile client group 100, controls the transmission output of the mobile client group 100 and the base station, soft hand-over between cells, and Determination of hard hand-over, transcoding and vocoding, global positioning system (GPS) clock distribution, and operation and maintenance of a base station are performed.

In addition, the switch in the mobile communication network 102 performs basic and additional service processing, incoming and outgoing call processing of subscribers, location registration and handover procedures of the mobile client group 100, interworking with other networks, and the like. . The exchange includes an Access Switching Subsystem (ASS) that performs distributed call processing, an Interconnection Network Subsystem (INS) that performs centralized call processing, a Central Control Subsystem (CCS) that centralizes operations and maintenance, and mobile. It includes a subsystem such as a Location Registration Subsystem (RLS) that performs storage and management of information for subscribers.

The home location register (HLR) 104 is a database that stores information on registered mobile communication terminals, and stores user information, MIN information, and the like of the mobile client group 100. In particular, the home location register 104 includes information for determining whether the mobile client is a user subscribed to the waiting service according to the present embodiment, and according to the determination result, the unreceived call history providing service information and the call It serves to transmit the waiting service information to the unlisted call history providing service server 108 to be described later.

The Short Message Service Center (SMSC) 106 provides a short message service environment within the mobile client group 100. For example, the short message information received from the mobile client 1 (100/1) can be processed and transmitted to the mobile client 2 (100/2), and linked with the unreceived call history providing service server 108 according to the present embodiment. The non-received call history providing service text and / or the short message information (including the calling number) during the call connection may be transmitted to the called subscriber, for example, the mobile client 2 (100/2).

The unreceived call log providing service server 108 provides the unreceived call log providing service text and call number information to the short message service center 106 when the unreceived call log providing service information is transmitted from the home location register 104. In the case where the unreceived call history providing service information and the call waiting service information are transmitted from the home location register 104, the short message service center 106 may transmit a short message “in call connection”. do. At this time, the unreceived call history providing service server 108, the mobile client, for example, the mobile client that is provided with the unreceived call history providing service, such as the mobile client 1 (100/1) due to a call collision due to the call waiting service When it is impossible, the management unit 108a which determines whether the mobile client 1 (100/1) subscribes to the busy waiting service and the mobile client 1 (100/1) is subscribed to the busy waiting service, the short message service center. And a transmission unit 108b for transmitting, to the mobile client 1 (100/1), a phrase indicating that the busy waiting service is in normal operation (106).

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figs. 2 and 3 attached to the unreceived call history providing service method in a mobile communication network according to another aspect of the present invention will be described in detail.

First, FIG. 2 is a flowchart illustrating an unreceived call log providing service call processing process when a called subscriber is in a normal call as a method of providing an unreceived call log in a mobile communication network according to another aspect of the present invention.

As shown in Fig. 2, the destination exchange 102a determines whether another call setup is requested while any destination subscriber, for example, mobile client 2 (100/2), is busy (S200). If another call setup is requested, the process proceeds to step S202.

In step S202, the destination exchange 102a transmits the busy state information to the home location register 104. That is, when the mobile client 2 (100/2) is a subscriber who is busy and does not use the "waiting on call service", the destination exchange 102a sends the home location register 104 with busy state information, for example, TTNR. Send (Transfer To Number Request). The reason for resetting at this time is set by the "Redirection Reason = Busy" parameter.

When the busy state information is transmitted, the home location register 104 transmits the busy response message to the destination exchange 102a as in step S204.

Thereafter, the home location register 104 determines whether an unreceived call log providing service is activated, and transmits unreceived call log providing service information to the unreceived call log providing service server (S206). In this case, the unreceived call log providing service information may be, for example, "SevInfoDirective including unreceived call log providing service, Redirection Reason = Busy".

Thereafter, the unreceived call log providing service server 108 will provide the service text and the calling number information of the unreceived call log providing service information to the short message service center 106 (S208).

The short message service center 106 that has received the service text and caller ID information of the unreceived call log providing service information has a short message of the unreceived call log providing service text, for example, the phrase "unreceived call log providing service-busy" and A short message including a calling number is generated and transmitted to the destination exchange 102a (210).

3 is a flowchart illustrating an unreceived call history providing service call processing process when a called subscriber is setting up a call as a method of providing unreceived call history in a mobile communication network according to another aspect of the present invention. That is, FIG. 2 is a service call processing process when the called party is in a normal call, while FIG. 3 is a service call processing process when the called party is not in a call but is establishing a call. It's a process.

As shown in FIG. 3, during a general call setup procedure between the originating exchange 102a and the destination exchange 102b, it is determined whether a second call setup is requested to the destination exchange 102b in a call (S300). ).

When a call establishment request for the busy state of the destination exchange 102b comes in, the destination exchange 102b receives the call waiting processing even if the called subscriber is using the Call Waiting service (CW service). It becomes impossible (S302) (S304).

Accordingly, the called exchange 102b determines that the called subscriber is in a busy state, and transmits busy state information to the called home location register (HLR) 104b (S306). At this time, the retransmission reason may be set to "Redirection Reason = Busy".

The incoming home location register 104b having received the busy state information determines whether the called subscriber is subscribed to the waiting service during the call (S308).

As a result of the determination in step S308, if the called subscriber is subscribed to the busy waiting service, the called home location register 104b proceeds to step S310 in which the service information and the busy information are received by the unreceived call history providing service server 108. The standby service information is transmitted (S408).

That is, in the present embodiment, after determining whether the called subscriber is aware that the unreceived call history providing service is activated, if the unreceived call history providing service is provided, even if the current waiting service is not available, the unreceived call history providing service The server 108 transmits the unreceived call history providing service information and the call waiting service information together. Conventionally, only the unreceived call history providing service information is transmitted when the waiting service is not available.

In this case, the unreceived call history providing service information may include "unreceived call history providing service, Redirection Reason = Busy".

Thereafter, the incoming call log providing service server 108 is associated with the short message service center 106, the phrase indicating the activation of the incoming call log providing service and call waiting service including the calling number, for example, "unreceived call log-call The short message "connecting" is transmitted to the called party with the calling number (S312).

That is, in the present embodiment, when the called subscriber is in a busy state due to a call collision and an unreceived call history providing service is provided, and the call waiting service is inactive, a short message "unreceived call history-busy" as in the prior art. Instead of the information, the short message information "unreceived call history-call is being connected" is provided to the called subscriber with the calling number, so that the user can recognize more accurate service status information.

As described above, the embodiments of the present invention have been described in detail, but the present invention is not limited to these embodiments, and various modifications may be made by those skilled in the art within the spirit and scope of the present invention described in the claims below.

According to the present invention, it is possible to accurately recognize the current state of the service to the called subscriber by accurately indicating the situation in the short message content of the unreceived call log providing service transmitted to the called subscriber, thereby increasing the service satisfaction for the subscriber. The activation of the service sector is expected to be maximized.
