Description

Apparatus and method for selectively making a call for an incoming voice call during a wireless data communication service and a method therefor {APPARATUS FOR SELECTIVELY CONNECTING SPEECH CALL TO A SUBSCRIBER CONNECTED TO A WIRELESS DATA COMMUNICATION SERVICE}

The present invention relates to an apparatus and method for selectively making a call connection to a voice call received from a wireless data communication service. More specifically, the present invention relates to a subscriber in the middle of receiving a wireless data communication service using a wireless data terminal device. An apparatus and method for selectively making a call connection to a corresponding voice call after notifying a subscriber in a wireless data communication service about a new voice call request to be made.

Wireless data communication services using wireless data terminal devices (e.g. mobile terminals, personal digital assistants, notebook computers, other intelligent terminals, etc.), in particular wireless data communication providing both voice calls and wireless data communication services A service refers to a service occupying a traffic channel, such as a wireless Internet service and a traffic occupying two-way text service.

The wireless Internet service supports the use of the wireless Internet in a terminal device that accommodates a HyperText Transfer Protocol (HTTP), a Wireless Application Protocol (WAP), or the like. Languages that can be implemented using HTTP include m-HTML (mobile-Hyper Text Markup Language) and c (compact) -HTML. Examples of WAP methods include WML (Wireless Markup Language) and HDML (Handheld Device Markup Language). ).

In recent years, the spread of wireless data terminal devices has been expanded, and wireless Internet users using these devices have been increasing.

In the conventional case, a voice message is disconnected during a call or a call is transferred to a voice mail system (VMS: Voice Mail System) without being notified of a call request requested during wireless data communication. It is supposed to leave.

In this case, the caller's desire to connect to the call becomes unsatisfactory, and in particular, the call is more frequent as the usage of the wireless data communication service increases due to the spread of the wireless data terminal device.

As such, as the number of users of wireless data communication services such as wireless Internet increases, the probability that a voice call connection cannot be made smoothly increases, resulting in a decrease in the actual rate of completion of the tangible call.

This is because the voice call path and the data path are different in the wireless data communication service network, so it is not easy to connect or transfer a new call connection notification.

One technique for solving this problem is to implement Internet Call Waiting (ICW) using Voice over IP (VoIP) technology.

As described above, the VoIP-based technology converts the voice data of subscribers who have newly requested a voice call connection into data based on VoIP (H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), etc.). It is a technology that enables voice calls by transferring to subscribers in data communication.

Such a technology has a limitation in that it is not provided to a general user because a separate VoIP function is additionally developed and installed in a wireless data terminal device.

In addition, since the corresponding function requires a lot of resources of the wireless data terminal device, the actual implementation takes considerable time.

In addition, since the voice is converted into data and transmitted, a data transmission speed in a network section may be a limiting factor in providing a service.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problem, and provides a voice call to a user who is in data service for a new voice call request attempted by a corresponding subscriber while receiving data service using a wireless data terminal device. The present invention provides a device and a method for connecting a voice call after notifying a user of a connection request so that the user can recognize the connection request and terminating the data service if the user desires it.

And selecting the connection with the new voice call, and when the subscriber selects the connection with the new voice call, connects the subscriber with the new voice call.

The data processor includes a subscriber status information processor that processes the subscriber's status information.

The subscriber's status information includes status information indicating whether the subscriber is currently using a wireless data communication service.

The voice call processing section inquires of the data processing section whether or not the call of the subscriber is due to the use of a wireless data communication service provided by the data processing section.

Another means of the present invention for achieving the above object comprises the steps of a first subscriber requesting a voice call to a second subscriber; Determining whether the second subscriber is busy; If it is determined that the second subscriber is busy, determining whether the second subscriber is busy due to the use of a wireless data communication service; If it is determined that the second subscriber is using a wireless data communication service, transmitting a message from the first subscriber to the second subscriber in a data format used in the wireless data communication service from the first subscriber. ; Allowing the second subscriber to select whether to conduct a voice call with the first subscriber; And when the second subscriber selects to conduct a voice call with the first subscriber, connecting a voice call between the second subscriber and the first subscriber.

Another means of the present invention for achieving the above object is a data processing unit for providing a wireless data communication service to the subscriber; And providing a voice call line between the subscribers, providing a connection path between the subscriber and the data processing unit, and when a new voice call is received for the busy subscriber, the call is provided by the data processing unit. A switch for processing the new voice call according to whether or not it is due to use, wherein the data processing unit receives the new voice call when the subscriber, which is the destination of the new voice call, is busy due to the use of a wireless data communication service. Notify the subscriber of the fact, causing the subscriber to select a connection with the new voice call, and the exchange selects the new voice call with the subscriber when the subscriber selects a connection with the new voice call. Connect. At this time, the previous wireless data communication service state is stored in the terminal device of the second subscriber so that the user can return to the previous state after the voice call.

After the subscriber ends the call with the new voice call, the subscriber can activate the stored wireless data communication service state to continue using the previous data service.

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 apparatus for selectively making a call connection to a voice call received during a wireless data communication service according to an embodiment of the present invention.

As shown in FIG. 1, an apparatus according to an embodiment of the present invention includes a switch 100, a home location register (HLR) 200, a voice call processor 300, and a data processor. 300.

The exchange 100 provides the wireless data communication service subscribers A and B with the wireless data communication service and the voice call service. In this case, a base station (not shown) and a base station controller may be included between the switch 100 and the subscribers A and B. If the subscribers A and B are not in the same base station, they are connected through another switch. Can be.

In the present embodiment, it is assumed that a mobile communication terminal, which is one of wireless data terminal devices that can use a wireless data communication service, is used. However, the present invention may be applied to a wireless data terminal device other than the mobile communication terminal.

The HLR 200 is connected to the exchange 100 and manages additional service information, location information, and the like for the mobile communication service subscriber.

The voice call processing unit 300 is connected to the switchboard 100, and if the subscriber corresponding to the voice call received by the switchboard 100, assumes that the subscriber A is busy, the voice call is This is a block for converting and processing a conventional VMS, a UMS (Unified Message System) and other ARS (Auto Response System).

The data processing unit 400 is connected to the exchange 100 and the Internet 500, and provides the subscriber A with a wireless Internet service or a traffic occupying bidirectional text service.

The voice call processor 300 requests the data processor 400 to inquire whether the subscriber A in a call is using a wireless data communication service, and the data processor 400 wireless data of the subscriber A. Whether to use a communication service is transmitted to the voice call processor 300.

The data processor 400 may transmit a message indicating that there is a new voice call request to the subscriber A who is using the wireless data communication service.

That is, the data processing unit 400 may include a wireless Internet function unit 410 for providing a wireless Internet service, a traffic occupying bidirectional text service providing unit 420 for providing a traffic occupying bidirectional text service, and status information of the subscriber A, In particular, it includes a subscriber status information processing unit 430 for processing wireless data communication service usage status information.

The wireless Internet function unit 410 and the traffic occupying bidirectional text service provider 420 of the data processor 400 may be selectively configured.

In the case of HTTP in the wireless Internet service, all operations are performed by a request and a response, so that the subscriber A may transmit a new voice call request message although a new data request is required.

After request and response from the wireless data terminal device, that is, the mobile communication terminal, if the TCP / IP / IP (Transmission Control Protocol / Internet Protocol) connection is established, the data processing unit 400 sends the corresponding data message to the mobile communication terminal. I can deliver it.

If the TCP / IP connection is not established, a data path establishment request may be attempted to the mobile communication terminal to transmit a corresponding data message.

In addition, when the data site to which the subscriber A is connected has a refresh function set and the mobile communication terminal periodically requests the system, the data site may immediately transmit the data message to the subscriber A.

At this time, the message delivered to subscriber A includes information that a new voice call has been attempted and a callback number for voice call connection.

When the subscriber A, who is using the wireless data communication service, receives the new voice call request, the voice call processor 300 connects the new request voice call B with the subscriber A. FIG. Further, when the voice call between the new request voice call B and the subscriber A ends, the previous wireless data communication service state stored in the mobile terminal of the subscriber A can be activated to use the continuous wireless data service. have.

Hereinafter, a method of selectively making a call connection with respect to a voice call received during a wireless data communication service according to an embodiment of the present invention will be described with reference to FIGS. 2A and 2B.

In the present embodiment, it is assumed that the subscriber B requests a voice call with the subscriber A while the subscriber A receives the wireless data communication service from the data processing unit 400 through the switch 100.

First, when the subscriber A requests a voice call with the subscriber A while the subscriber A uses the wireless data communication service from the data processing unit 400 via the switch 100 (S100), the subscriber B ) Switch in the region in which is located (in this embodiment assumes subscriber A and subscriber B are in the area controlled by the same exchange 100) 100 to HLR 200 By requesting the location information, HLR 200 provides the location information of the subscriber (A) to the switch 100, the exchange 100 is able to know the location of the subscriber (A) (S110). At this time, the process of finding the called subscriber is to obtain the location (path) information of the called subscriber in the HLR (200), and in the reverse order to get the location (path) information in the HLR is connected to the exchange is accepted again The case is all possible.

If the subscriber A is registered in the same area as the subscriber B, in particular in an exchange station controlled by the same exchange 100, the exchange 100 determines whether the subscriber A is currently in a call. (S120).

On the other hand, when the subscriber A and the subscriber B are located in different areas, the exchanger connected to the subscriber B finds the exchange 100 in the area where the subscriber A is located and is connected to the subscriber A. The process of checking the busy state of the device is already known, and in the present embodiment, the subscriber A and the subscriber B are located in the same area and are controlled by the same exchange 100. It will be readily understood by those skilled in the art that the operations located in the area and controlled by other exchanges.

If subscriber A is not currently busy, exchange 100 connects subscriber B's voice call request call to subscriber B so that voice calls between subscriber A and subscriber B can be made ( S130).

On the other hand, when the subscriber A is currently in a call, the exchange 100 switches the voice call of the subscriber B to the voice call processor 300 (S140).

After the voice call processing unit 300 holds the received voice call of subscriber B, which has been switched from exchange 100, in a non-charged state, whether the busy state of subscriber A is due to the use of a wireless data communication service. In order to determine this, the data processor 400 inquires whether the subscriber A uses the wireless data communication service (S150).

The data processing unit 400 receives an inquiry of whether to use the wireless data communication service for the subscriber A from the voice call processing unit 300, and then retrieves a status of the subscriber A from the subscriber status information processing unit 430 and retrieves the search result. The result is transmitted to the voice call processor 300 (S160).

The voice call processing unit 300 receives the inquiry result from the data processing unit 400 and determines whether the subscriber A is currently using the wireless data communication service (S170).

If it is determined that the subscriber A does not use the wireless data communication service, the voice call processing unit 300 transfers the voice call received and converted from the subscriber B as in the prior art to the VMS, UMS, or other ARS. (S180).

On the other hand, if it is determined that subscriber A is using a wireless data communication service, voice call processing unit 300 informs subscriber A that a new voice call from subscriber B has been received to data processor 400. Notify (S190).

At this time, the voice call processing unit 300 stores information such as a line number and the like of the call used when the subscriber A's number and the diverted call is connected to the voice call processing unit 300 in an internal database.

When the data processing unit 400 is notified from the voice call processing unit 300 that a new voice call has been received for the subscriber A in use of the wireless data communication service, the data processing unit 400 reports the fact to the wireless data communication currently in use by the subscriber A. The notification message is configured in the form of a service and transmitted to the subscriber A (S200), and the notification message is displayed on the mobile communication terminal of the subscriber A (S210).

At this time, the data processing unit 400 determines whether the subscriber A uses the wireless Internet service through the wireless Internet function unit 410 or the traffic occupying bidirectional text service through the traffic occupying bidirectional text service unit 420. According to determine the message type to be sent to the subscriber (A).

In addition, as described above, in the case of the wireless Internet service, the message should be delivered in a different manner depending on whether the TCP / IP connection is established or whether the refresh function of the access site is set.

On the other hand, the data processing unit 400 sends a message that there is a new voice call request for subscriber A, and at the same time sends a message that allows subscriber A to choose to connect to the new voice call. In this case, the message includes a callback number for voice call connection.

For example, if a message is displayed to subscriber A such as "There is a new voice call attempt. Please select 1) for connection and 2) for standby." While in use, you can see that you have a new voice call attempt. If you want to access the new voice call, press the "1" key. In this case, the function of "wait" is given to the second key, but various functions such as "access denied", "hold", "voice mailbox connection", and "continue previous service" can be granted. have.

On the other hand, when subscriber A knows that a new voice call is received while using the wireless data communication service, and does not want to connect to the voice call at present, the voice call processing unit 300 receives from subscriber B as in the prior art. Then, the converted voice call is connected to VMS, UMS, or other ARS (S230).

If the subscriber A wants to stop the current wireless data communication service and access the new voice call, the subscriber A accesses the voice call processor 300 using the callback number. The voice call processing unit 300 compares and retrieves the connected calling party number and the calling party number stored in the internal database, and the voice call of the subscriber B switched to the voice call processing unit 300 using the line number of the corresponding stored call. The subscriber A in use of the wireless data communication service is connected to form a call path (S240). At this time, the state of the wireless data communication service being used by the subscriber is stored in the subscriber's mobile communication terminal or data processing unit 400.

After the subscriber terminates the call with the new voice call, the subscriber can continue to use the old data service by activating the wireless data communication service state stored in the subscriber A's mobile terminal.

As such, when the subscriber A, who is using the wireless data communication service, connects to a new voice call and performs a voice call with the subscriber B, and ends the voice call, the subscriber A's mobile communication terminal returns to the previous voice call. After activating the wireless data communication service state and subsequently accessing the data processing unit 400 for a new data request, the wireless data communication service is switched to the previous data service environment and the wireless data communication service continues.

On the other hand, unlike the above description, when the exchange 100 has a separate portion that can be directly connected to the data processing unit 400, and the subscriber A is in a call, the exchange 100 directly connects to the data processing unit 400. Inquiring whether the subscriber A is using the wireless data communication service, and receiving the result that the subscriber A is using the wireless data communication service, the voice call of the subscriber B is transmitted to the separate VMS, It may be possible to connect to UMS and other ARS systems.

At this time, in order to indicate that the call is a new call for data service subscriber connection, the corresponding information is set and delivered on the network connection protocol (SS7 ISUP (ISDN User Part), R2-MFC).

In this way, since the switch A 100 directly determines that the called party A is in data service, the call transfer to the restricted system can be selectively performed.

In addition, although the subscriber A inquires to the data processing unit 400 to know whether the wireless data communication service is in use, the HLR 200 determines whether the switch 100 is using the wireless data communication service of the subscriber A. ) May be set. In this case, a path for transferring information between the HLR 200 and the data processor 400 should be added.

In addition, the exchange 100 accommodates the subscriber A to receive the call through the HLR 200-the exchange 100-in this embodiment, the exchange 100, but the subscriber A must be connected through an exchange in another region. In case of requesting route information to the exchange, the destination exchange directly informs the HLR 200 that the subscriber A is using the wireless data communication service, thereby using the data service in the HLR 200. Whether information may be set.

At this time, when the information is not stored in the HLR 200 and is transmitted to the originating exchange, the originating exchange may switch the call to a VMS, UMS, and other ARS directly connected to the call.

Although the present invention has been described with reference to the most practical and preferred embodiments, the present invention is not limited to the above disclosed embodiments, but also includes various modifications and equivalents within the scope of the following claims.

According to the present invention, a subscriber can know that a new voice call is requested from another subscriber even while the subscriber is receiving a wireless data communication service using the wireless data terminal device, and the subscriber can request the new voice call. Voice call becomes possible.
