In addition, the following communication network will be described using a wideband code division multiple access (WCDMA) network as an example, of course, a code division multiple access (CDMA) network having a corresponding component, a global system for mobile communication (GSM) network, It will be apparent through the following description that the same may be applied to all communication networks such as a general wired telephone network.

1 is a block diagram schematically illustrating an entire system for providing a forwarding service of a terminal according to an exemplary embodiment of the present invention, and FIG. 2 is a data format in which forwarding control information is described according to an exemplary embodiment of the present invention. 3 is a diagram showing the structure of user-user information (UUI) according to an embodiment of the present invention.

Referring to FIG. 1, the entire system includes a forwarding function terminal 10, a communication network 50, and a forwarding control terminal 100.

The forwarding function terminal 10 is a terminal that performs a forwarding function, and identifies identification information (for example, a phone number, etc.) of a terminal to be forwarded (hereinafter, referred to as a "called terminal", of course, the forwarding control terminal may be a called terminal). The forwarding service request message including a) is transmitted to the communication network 50. Accordingly, the communication network 50 forwards the incoming call to the forwarding function terminal 10 or the received SMS, MMS, etc. message to the terminal according to the phone number included in the forwarding service request message. .

The communication network 50 includes a base station, an exchange, a location register (HLR or VLR), and the like. As described above, the communication network 50 according to the present invention will be described below using the WCDMA network as an example. Particularly, the exchange of the communication network 50 has a function of switching a call and / or a message, which is subsequently made to the forwarding function terminal 10, to a predetermined destination terminal according to a forwarding service request received from the forwarding function terminal 10. To perform. It will be apparent to those skilled in the art to perform call forwarding at the exchange, and thus a detailed description thereof will be omitted.

The forwarding control terminal 100 transmits the forwarding control information for causing the forwarding function terminal 10 to perform the forwarding function to the forwarding function terminal 10 through the communication network 50. That is, a user who leaves the forwarding function terminal 10 at home and sets the forwarding function of the forwarding function terminal 10 remotely using the forwarding control terminal 100 (for example, a mobile terminal of a coworker). Can be.

The forwarding control information includes identification information of the called terminal (for example, a telephone number and a mobile identification number (MIN)). For convenience of explanation, for example, a user who has left his or her mobile terminal having a forwarding function (that is, the forwarding function terminal 10 here) at home is a mobile terminal of an office co-worker (that is, forwarding here). By generating the forwarding control information using the control terminal 100 and transmitting it to the mobile terminal through the communication network 50, the mobile terminal can perform the forwarding function.

The forwarding control terminal 100 may transmit forwarding control information in the process of requesting and setting up a call to the forwarding function terminal 10. The forwarding control terminal 100 may include forwarding control information in a call control setup message which is one of messages transmitted during a call setup process in a WCDMA network. That is, the forwarding control terminal 100 requests a call to the corresponding forwarding function terminal 10 through the communication network 50 and transmits the forwarding control information to the call control setup message, which is one of the messages transmitted during the call setup process. As a result, the forwarding function terminal 10 may perform the forwarding function. In the WCDMA network, the call control setup message is transmitted to the receiving side (ie, the forwarding function terminal 10) before alerting is performed when attempting to set up a call. The forwarding control terminal 100 may write forwarding control information in a user-user field of the call control setup message.

In summary, the forwarding control terminal 100 attempts to set up a call to the forwarding function terminal 10 and includes forwarding control information in a signal message (call control setup message) having user information among signal messages transmitted in a call setup process. send. Subsequently, upon receiving the response message according to the call setup from the forwarding function terminal 10, the forwarding control terminal 100 recognizes that the forwarding control information is properly transmitted and releases the call setup.

The user-user field of the call control setup message among the signal messages in which forwarding control information is described is shown in FIG. 2. The user-user field includes user-user information (UUI), and up to 128 octets of data may be described in this field. That is, the forwarding function terminal 10 may describe the forwarding control information in the UUI.

Referring to FIG. 3, the UUI may consist of a forwarding control data identifier, a forwarding control data length, and a forwarding control data item. The forwarding control data identifier is information for the forwarding function terminal 10 to recognize that the corresponding message is a forwarding control message, and the forwarding control data length has information about the length of the forwarding control data. The forwarding control data may include a service code (SC) having identification information of the corresponding service (information on performing / release of the forwarding function) and related information (SI: supplementary information) according to the forwarding control. In particular, the SI may include telephone number information (SIA: supplementary information A) to be forwarded and service type information (SIB: supplementary information B) regarding whether the forwarding is an incoming call or a message. As described in the forwarding control data item. For example, the value "21" (for example, "22" is the forwarding function is released) for informing the SC to perform the forwarding function, and the destination terminal telephone number "01011112222" to the supplementary information A (SIA), the supplementary (SIB) In information B), service type information (for example, "11" for incoming call forwarding, "16" for SMS forwarding, etc.) for whether the forwarding is an incoming call or an incoming message may be described in the UUI. have. Therefore, the forwarding function terminal 10 receiving the forwarding control information executes the forwarding function, and then the call to the forwarding function terminal 10 is forwarded to the terminal of the telephone number "01011112222".

Here, when both the incoming call and the received message are forwarded by default, it is natural that the SIB, which is information on whether the forwarding call is the incoming call or the received message, need not be used.

In addition, the forwarding control data may further include additional information such as time information for performing the forwarding function. For example, when the forwarding service is to be performed only from 1:00 pm to 3:00 pm, the data according to "PM13: 00-15:00" may be further included in the forwarding control data.

Hereinafter, a process of performing a forwarding service of a terminal according to the present invention will be described.

4 is a diagram illustrating an entire process of performing a forwarding service according to an embodiment of the present invention.

Referring to FIG. 4, in step 410, the forwarding control terminal 100 generates forwarding control information corresponding to a signal input from a user. As described above, the forwarding control information is information for causing the forwarding function terminal 10 to perform the forwarding function, and includes a telephone number of the called terminal.

In step 420, the forwarding control terminal 100 requests a call to the forwarding function terminal 10 to the communication network 50, and transmits the forwarding control information in a signal message transmitted during the call setup process. In the drawing, the call request and the forwarding control information are simultaneously transmitted. However, this is for convenience of description, and the forwarding control information is included in a signal message such as a call control setup message transmitted during the call setup process as described above. Can be sent.

In operation 430, the communication network 50 transmits an incoming call to the corresponding forwarding function terminal 10 and transmits forwarding control information received from the forwarding control terminal 100.

In operation 440, the forwarding function terminal 10 transmits a response to the incoming call to the forwarding control terminal 100, which is an originating terminal, through the communication network 50. Receiving the response, the forwarding control terminal 100 recognizes that the forwarding control information has been properly transmitted to the forwarding function terminal 10, and transmits a release signal message according to the request for release of the call requested in step 450 to the communication network 50. Thus, in step 460 the call is released.

 Here, the call release is more preferably performed before the communication network 50 transmits an alerting message (a message for causing the called terminal to perform an incoming call notification such as a bell or a vibration) to the forwarding function terminal 10. .

In step 470, the forwarding function terminal 10 performs the forwarding function according to the received forwarding control information. That is, the forwarding function terminal 10 recognizes and forwards the forwarding control information included in the signal message (for example, the UUI of the user-user field of the call control setup message as described above) received during the call setup process. A forwarding service request message including identification information of the terminal is generated and transmitted to the communication network 50 in step 480.

Therefore, in step 490, the communication network 50 registers identification information (for example, telephone number, MIN, etc.) and called terminal identification information (for example, telephone number) of the forwarding function terminal 10 that requested the corresponding forwarding service. Thus, forwarding service according to a call or message (SMS, MMS, etc.) to the forwarding function terminal 10 is provided.

FIG. 5 is a diagram illustrating a processing procedure of a forwarding control terminal for a forwarding service according to an exemplary embodiment of the present invention, and FIG. 6 is a diagram illustrating processing of a forwarding function terminal for a forwarding service according to an exemplary embodiment of the present invention. A diagram showing the process.

Referring to FIG. 5, the forwarding control terminal 100 executes a forwarding control application according to a user's command input in step 510, and receives control information for a forwarding service in step 520. Control information includes a phone number of the forwarding function terminal 10, a phone number of the terminal to be forwarded, and may further include a service type (call or message). The user interface screen according to the forwarding control application will be described later with reference to related drawings (FIGS. 7 and 8).

In step 530, the forwarding control terminal 100 encodes the forwarding control information by using the input control information. That is, the forwarding control terminal 100 encodes the forwarding control information in a format according to a signal message transmitted during call call setup.

In step 540, the forwarding control terminal 100 attempts to call the forwarding function terminal 10 by using the input phone number of the forwarding function terminal 10, and accordingly, forwarding control information is included in step 550. Send a signaling message (ie call control setup message).

In operation 560, the forwarding control terminal 100 determines whether a response message is received from the forwarding function terminal 10 through the communication network 50. That is, it is determined whether a call control alert message, which is a response message according to the call control setup message, is received from the communication network 50. In general, the originating terminal attempting a call repeats the call control setup message periodically and transmits a predetermined number of times or less until the call control alert message is received. For example, the originating terminal sends a call control setup message up to 10 times at 1 second intervals until a response message is received, and notifies the call connection failure if no response message is received. That is, the forwarding control terminal 100 may transmit the call control setup message up to a predetermined number of times (eg, 10 times) until the response message is received, and finally notify the call setup failure when the response message is not received. .

If the call control alert message (response message) is received, the forwarding control terminal 100 requests the call release to the communication network 50 in step 570. That is, the forwarding control terminal 100 transmits a call control release message to the communication network 50 to request the release of the set call or the set call.

In operation 580, the forwarding control terminal 100 determines whether a call control release complete message is received from the communication network 50. If the response message according to the call release is received, the user is notified that the forwarding function control of the forwarding function terminal 10 is successfully performed, and the forwarding control application is terminated.

Even if a response message according to the call release request has not been received from the communication network 50, since the call control alert message has already been received, it may be notified of success. However, as shown in the drawing, in order to transmit the forwarding control information at step 590, It may also indicate a failure. In this case, the user may receive a retry command from the user or automatically forcibly release the call and proceed to step 540 again.

Hereinafter, a process according to a forwarding service in the forwarding function terminal 10 that receives the forwarding control information will be described with reference to FIG. 6.

Referring to FIG. 6, the forwarding function terminal 10 receives a call control setup message transmitted from the forwarding control terminal 100 in step 610, and decodes a user-user field of the call control setup message in step 620. do.

Recognizing the contents of the user-user field in step 630, the forwarding function terminal 10 determines whether the received message is a forwarding control message. When the forwarding control information is included in the user-user field, the forwarding function terminal 10 may recognize that the cone control setup message is a forwarding control message for performing a forwarding function instead of a message for general telephone connection. That is, the forwarding function terminal 10 recognizes the forwarding control message through the forwarding control data identifier (see FIG. 3) of the forwarding control information.

If the received call control setup message is not a forwarding control message but a message for general call setup, the forwarding function terminal 10 performs normal call processing in step 640. If it is a forwarding control message, the forwarding function terminal 10 executes a forwarding application in step 650, and extracts forwarding control information from the user-user field of the call control setup message in step 660 to perform a forwarding function. do. That is, in step 670, the forwarding function terminal 10 requests a forwarding service to the communication network 50.
