PURPOSE: A method for controlling a CNIP(Calling Number ID Presentation) function in the CDMA communication system is provided so that a calling subscriber can determine the display of his caller ID and a called subscriber can select and dial up a caller ID after confirming the numbers displayed on his terminal. CONSTITUTION: If calling subscriber information is requested to a VLR(Visitor Location Register) from an origination side base station controller(S11), an origination side mobile station call processing module notifies the calling subscriber information request to the VLR(S12). If the mobile station call processing module requests call routing information to an HLR(Home Location Register)(S13), the HLR transmits a calling number input request information broadcast for a CNIP function to the mobile station call processing module(S14). The HLR checks whether a calling number is inputted from the mobile station call processing module(S15).

Description

Method for controlling of originating number display in CDMA mobile communication system}

The present invention relates to caller ID display control in a code division multiple access (CDMA) mobile communication system. Particularly, in displaying a caller ID on a called terminal, the caller decides the display of the caller ID and the receiver uses his or her own. Calling number display control method in a CDMA mobile communication system to check the calling number displayed on the called terminal and to select and call.

In general, a CDMA mobile communication system includes a mobile station (MS) capable of making a call while moving, a base station (BTS) that communicates wirelessly with the mobile station, a control station (BSC) controlling the base station, and a wired connection with the control station. And a mobile communication exchange (MSC) for switching a call and a home location register (HLR) connected to the mobile communication exchange and storing subscriber information. The mobile station and the base station communicate wirelessly. And call switching to connect the calling signal to the called party during data communication so that data (calling party and called party) and the call are made.

In such a general CDMA mobile communication system, there is a Calling Number ID (CNIP) function for displaying a caller's information to a called party. Of course, this is an additional service that is made only for subscribers registered for the calling number display function, hereinafter called called party and caller means the subscriber who registered the calling number display function.

In other words, when a caller who registers a caller ID display function generates a call, the caller ID is displayed unconditionally to the called party's terminal registered with the caller ID display function. The called party then sees the calling number displayed and attempts to make a selective call. That is, the called party can selectively call by looking at the displayed calling number and answering only when he / she wants to make a call.

However, such a general caller ID display function displays the caller's number unconditionally to the called person regardless of whether the caller's caller ID is transmitted or not, and thus the caller's intention is completely ignored.

That is, even if the caller does not want to inform the other party of his / her calling number, the calling party number is unconditionally displayed on the called terminal irrespective of the caller's intention, so that the privacy of the individual may be violated.

Therefore, the present invention has been proposed to solve various problems occurring when performing the calling number display function in the general mobile communication system as described above.

An object of the present invention is to allow a caller to determine the display of the calling number in displaying the calling number on the called terminal, and the receiver checks the calling number displayed on his called terminal and selects and selects the call. The present invention provides a method for controlling caller ID display.

The present invention (method) for achieving the above object,

When a caller makes a call, the caller is requested to enter a phone number to decide whether or not to forward the caller's number to the caller, and the caller displays the caller's number so that the call can be made selectively.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention according to the technical spirit as described above in detail.

1 is a schematic configuration diagram of a CDMA mobile communication system to which a calling number display control method according to the present invention is applied.

Here, reference numeral 10 denotes a control station (BSC) for controlling the base station, and includes a call control module 11. In addition, reference numeral 20 denotes a control station matching module 21, a mobile station call processing module 22, a visitor location register 23, and a control station map application unit 24 (MSAP: MSC MAP Application) as a mobile communication switch (MSC). And reference numeral 30 is a home location register (HLR) that stores subscriber information.

The CDMA subscriber registers a Caller ID service function, which is an additional service function that he / she wants. Here, the Caller ID service generally refers to a function of allowing a called party to select and make a call for a call received by a subscriber, and the Caller ID service function according to the present invention requires a caller to input a phone number and receives the call. Call screen function by the subscriber to display on the terminal to allow the called party to determine whether to call.

In the state where the additional service function is registered as described above, when the subscriber transmits a call signal, the subscriber receives the call signal from the call control module 11 in the control station 10 and delivers it to the control station matching module 21 of the exchange 20. do. The control station matching module 21 transmits a call signal of the terminal to the mobile station call processing module 22, and the mobile station call processing module 22 for calling party (hereinafter, referred to as "caller") information and subscriber location confirmation. The information is checked in the database of the visitor location register 23, and the subscriber information is requested to the subscriber home location register 30 via the control station map application 24 in charge of the map message transmission.

The home location register 30 delivers the subscriber's call / receive information to the control station map application unit 24, which transmits it to the mobile station call processing module 22. The mobile station call processing module 22 checks the called party's additional service information (Caller ID) among the called subscriber (hereinafter referred to as "called party") information obtained from the home location register 30, and checks the added service information of the called party. Transfer to control station matching module 21. The control station matching module 21 then notifies the call control module 11 in the control station 10 of the called party's Caller ID.

Next, the mobile communication switch 20 requests an input announcement broadcast of the calling party number to the terminal, and the request voice of the announcement announcement of the calling party number is sequentially transmitted through the control station 10 and the base station (not shown). Is passed to. The caller then enters the calling number via the keypad when the call is desired. If the caller does not enter the calling number, the call is terminated without being set up.

The calling number input through the calling terminal is transmitted to the control station matching module 21 in the mobile communication switch 20 through the base station and the control station 10 in sequence, and the control station matching module 21 transmits this to the mobile station call processing module. Pass it to (22). The mobile station call processing module 22 passes the map parameter CNIdigitASCII for displaying the calling number through the control station map application unit 24 to the home location register 30.

The home location register 30, which has received the map parameter for displaying the calling number, forwards the call to the mobile switching center 20 by giving the called subscriber routing number (Routing Number), and the mobile switching center 20 rings the called terminal. When ringing, the calling party number (calling number) is transmitted to the called terminal so that the calling number is displayed on the display unit of the called terminal. The called party checks the calling number displayed on the display unit and presses the call button if he / she wants to talk, and rejects the call by pressing the call end key if he / she does not want to call. This allows the called party to make selective calls.

The subscriber presses a Caller ID activation / deactivation feature code and a transmission key (SEND key) through the mobile terminal (MS) 10. The mobile communication switch 20 which has received the additional function code string (the column of the digit including the additional function code) from the corresponding terminal receives the feature request signal (FEATREQ) including the additional function code string, dialed digits, and transaction capability. ) Is sent to the home location register 30. Here, the FEATREQ transmitted from the mobile communication switch 20 to the home location register 30 is MIN (unique number of the terminal), ESN (electronic serial number of the terminal), and BILLID (FEATREQ of the terminal), as shown in FIG. If the result is call routing, the call identifier used for billing and rerouting purposes, DGTSDIAL (additional code string entered by the terminal), SENDERIN (calling node identification number), TRANSCAP (for the system currently in service) Transaction processing capability), OTFI (current add-on active state).

The home location register 30 then recognizes the caller ID activation / deactivation request with the delivered feature code, and activates or deactivates the caller ID accordingly. That is, if it is determined that the Caller ID can be appropriately processed based on the received information, the processing is performed and the featreq is returned to the mobile communication switch 20 at the same time. The response from the home location register 30 in this procedure includes a command for the system in service to set up a call, and the map parameter of the returned featreq is shown in FIG. 8B. That is, the featreq map includes FEATRESULT (additional feature request result information), ACTCODE (process code for the terminal, if not included, according to the FEATRESUIT value), and ANNLIST (if not included as a tone and announcement list, follow the FEATRESULT value). , DMHData (Data for DMH recording), TERMLIST (Calling Information), GRPINFO (Information related to group routing), OTFI (current add-on enabled state), ROUTDGTS (as a specific routing command, applicable and not specified in the TerminationList parameter If not included), TERMTRIG (activated incoming trigger points).

When the mobile communication switch 20 receives the Featreq from the home location register 30, the mobile communication switch 20 confirms the Featreq to the mobile terminal 40 and releases the call.

Here, reference numeral 20 denotes a mobile communication exchange that manages a mobile terminal that has originated a current call, 30 is a home location register, and 50 is a large mobile communication exchange that manages services of a called terminal.

As shown, when a subscriber makes a call (Call Orignation), the calling mobile telecommunication switch 20 requests location information for obtaining call processing information from the home location register 30 (LOCREQ). Here, the LOCREQ transmitted from the calling mobile communication switch 20 to the home location register 30 is BILLID (when the result of the LOCREQ is call routing, as shown in FIG. 9A, used for the purpose of charging and rerouting). Incoming call identifier), OrigID (identification information of calling mobile switching center, MSCID of calling mobile switching center, including SS7 carriage services as PC_SSN of calling mobile switching center), DGTSDIAL (called calling party identification digit), TRANSCAP (The transaction processing capability of the calling system), the Termination Access Type (TAT) identifying the specific access situation.

Receiving the location information request signal, the home location register 30 recognizes that Caller ID is activated from the service profile of the subscriber, and obtains the subscriber number from the subscriber. Invoke (RUIDIR). Here, RUIDIR for obtaining a subscriber number is represented by MIN (MIN of a terminating mobile terminal), ESN (ESN of a terminating mobile terminal), MSCID (MSCID of a mobile switching center), ANNLIST (tone and announcement). If not included in the list, announcements follow other parameters in the response), RoutingInfo (call routing information; TerminationList if termination list is allowed; Digits (Destination) if termination list is not allowed with call routing information. RoutingDigits is included if not specified in the TermList as a special routing instruction. Digits (carrier) is included if not specified in the TermList as the recipient's PIC), and DMHData (Data for DMH recording).

On the other hand, the originating mobile communication exchanger 20 receiving the RUIDIR transmitted from the home location register 30 stops the LOCREQ timer (LRT), waits for a subscriber number after answering a call to the subscriber (Answer Call, Prompt for Caller ID). Thereafter, when the subscriber enters the subscriber number, it is transmitted to the calling mobile communication exchange 20, and the calling mobile communication exchange 20 receiving the subscriber number performs a specific user control function operation with the home location register 30. Send ruidir (eg, announcement and digit collection) to resume the LRT. Here, the ruidir transmitted to the home location register 30 includes a DGTCC (digit collection parameter definition) and an ANNLIST (list of tones or announcements) as shown in FIG. 10A.

The home location register 30, which has received the ruidir transmitted from the calling mobile telecommunication switch 20, includes a subscriber number received in the CNIdigits ASCII to obtain routing information, and sends a routing request to the mobile telecommunication switch 50. Request) Deliver the message.

After receiving the routing request message, the mobile switching center 50 performs the requested user control function, allocates a TLDN, and returns a routing request result to the home location register 30. The routreq sent here to the home location register 30 includes DGTSDIAL (digits collected from the user), as shown in FIG. 10B.

Receiving the TLDN, the home location register 30 sends the location request result to the calling mobile communication switch 20 including the TERMLIST, REDIND, and ANNLIST parameters (locreq). Receiving the location request result, the calling mobile communication exchange 20 provides a confirmation tone to the subscriber and sets up a call (call setup). Receiving a call setup message (call setup), the mobile switching center 50 to the destination terminal, including the Caller ID alerts. The called party then sees the Caller ID displayed on the terminal and decides whether to receive the call.

Here, reference numeral 40 is a calling party mobile terminal, 20 is a calling party mobile communication switch, which includes a mobile station call processing module 22 and a visitor location register 23, 30 is a home location register, and 50 is a called party. A large mobile communication switch that manages a terminal includes a mobile station call processing module 51, and 60 is a called party's mobile terminal.

When the calling mobile terminal 40 issues a call setup request (Setup-IC), the call setting request signal is transmitted to the calling mobile communication exchange 20 through the base station and the control station in sequence, and the calling mobile communication exchange ( Mobile call processing module 22 in 20 sends an InfoOGSetup message to visitor location register 23. Upon receiving this, the visitor location register 23 transmits a response signal InfoOGSetupAck to InfoOGSetup to the mobile station call processing module 22. The mobile station call processing module 22 receiving the response signal for InfoOGSetup requests the mobile station routing information (received subscriber location information and additional service information, etc.) to the home location register 30 (LocationReq), and receives the home location. The registrar 30 performs an additional service function by performing tone and announcement broadcasting with the mobile station call processing module 22 (RmtUserInfoDir). Then, the mobile station call processing module 22 transmits a guide broadcast (that is, a guide broadcast for inputting a caller number) to the calling mobile terminal 40, and when a caller number is input from the mobile terminal 40 (digit input), A response message (RmtuserInfoDirAck) in response to the interaction with the home location register 30 is sent to the home location register 30. Receiving a response message for the mutual operation, the home location register 30 transmits a response signal (LocationReqAck) to the mobile station call processing module 22 for the location information request. Then, the mobile station call processing module 22 transmits an InfoICSetup message to the visitor location register 23, and the visitor location register 23 receives the response signal (InfoICSetupAck) to the mobile station call processing module 22. do. The mobile station call processing module 22 receiving the response message (InfoICSetupAck) notifies the called party information message (CdSubsInfoRP) to the mobile station call processing module 51 in the called party mobile communication switch 50, and sends the called party information message. The mobile station call processing module 51 in the received mobile station mobile communication exchange 50 requests call setup to the control station controlling the base station associated with the called party's mobile terminal 60 (Setup_CI).

When the subscriber originates a call (Call Origination), the calling mobile telecommunication switch 20 invokes LOCREQ [DGTSDIAL, CNIdigitsBCD] requesting mobile station routing information to the home location register 30. Receiving the LOCREQ message, the home location register 30 recognizes that the caller ID is activated from the subscriber's service profile and establishes a RUIDIR (Remote User Inferaction Directive) with the calling mobile communication switch 20 to obtain the subscriber number from the subscriber. Invoke. The calling mobile communication switch 20 then stops the LOCREQ timer (LRT) and waits for a subscriber number from the subscriber. After the subscriber enters the calling number, the calling mobile communication switch 20 receives the ruidir to the home location register 30 after receiving it and resumes the LRT. The home location registrar 30 invokes the routing request to the called party's mobile switching center 50 by including the received subscriber number in CNIdigits ASCII to obtain routing information. Accordingly, the called party mobile communication exchange 50 allocates the TLDN and returns the routing request result to the home location register 30. Receiving the TLDN, the home location register 30 returns the location request result to the calling mobile communication switch 20 including the TERMLIST, REDIND, and ANNLIST parameters. The calling mobile telecommunication switch 20 provides the subscriber with a confirmation tone and establishes a call. And the call setup message (call setup) is transmitted to the called party mobile communication switch 50, the called party mobile communication switch 50 receiving the call setup message is the incoming subscriber is busy (Busy) state and CW activation Knowing the status, the call waiting alert including the Caller ID to the called terminal.

Figure 7 shows a caller ID service processing procedure associated with the CFU.

When the subscriber originates a call (Call Origination), the calling mobile communication exchange 20 invokes a location information request message (LOCREQ [DGTSDIAL, CNIdigitsBCD]) to the home location register 30. Receiving the location information request message, the home location register 30 recognizes that the CFU and Caller ID are activated from the service profile of the subscriber, and receives a subscriber number from the subscriber to the calling mobile communication switch 20 to the RUIDIR (Remote User). Invoke Inferaction Directive. The calling mobile communication switch 20 then stops the LOCREQ timer (LRT) and waits for a subscriber number from the subscriber. After the subscriber enters the calling number, the calling party mobile communication switch 20 receives the message and transmits ruidir to the home location register 30 and resumes the LRT. The home location register 30 returns the location request result to the calling mobile communication switch 20 including TERMLIST, REDIND, ANNLIST, and RNDGTS, and ALRTCODE, CNIdigitsASCII (including the Caller ID) to the called mobile communication switch 50. Invoke the Infomation Directive, including Here, the INFODIR transmitted by the home location register 30 to the called-side mobile communication switch 50 to provide a designated notification to the roaming mobile terminal is MIN (refer to FIG. 12A). MIN), ESN (ESN of the mobile terminal), ALRTCODE (including when the mobile terminal is alerted with the type of alert signal to apply), and ANNLIST (tone and announcement list). On the other hand, the calling party mobile communication switch 20 performs the call transfer to the called party number in the TERMMLIST, the called party mobile communication switch 50 is CFU Alert to the called terminal. The destination mobile communication exchange 50 transmits an information directive return result to the home location register 30 including the CFU alert result (routreq [ALRTRES]).

Fig. 11 shows an INFODIR (Information Directive) operation process used by the home location register to instruct the destination mobile communication exchange to provide a notification designated to an idle mobile terminal (MS).

The home location register 30 transmits INFODIR [MIN, ESN, ALRTCODE, ANNLIST] as shown in FIG. 12A to the mobile switching center 50 to provide the designated notification to the roaming mobile terminal. The visitor location register 70 then transmits the INFODIR [MIN, ESN, ALRTCODE, ANNLIST] to the calling party mobile communication exchange 50. Upon receiving this, the mobile switching center 50 notifies the mobile terminal 60 in an appropriate manner (MS alert). The mobile communication exchange 50 then sends infodir [ALRTRES] to the visitor location register 70. Where infodir includes an ALRTCODE (including if the ALRTCODE of FIG. 12A requested the result as a result of the notification attempt), as shown in FIG. 12B. The visitor location register 70 then delivers infodir [ALRTRES] to the home location register 30.

Figure 13 shows an embodiment of a caller ID display control method according to the present invention.

This is a flowchart showing the Caller ID service function in a general case.

As shown, if outgoing subscriber information is requested from the calling party control station to the visitor location registrar in step S11, the calling party mobile station call processing module notifies the outgoing subscriber information request to the visitor location registrar in step S12. If the mobile station call processing module requests call routing information to the home location register in step S13 (information request for call reception), the home location register sends a call number input request for the Caller ID function to the mobile station call processing module in step S14. Deliver the broadcast. The mobile station call processing module, which receives the message, transmits a guide broadcast requesting the input of the calling number to the calling mobile terminal. After step S15 checks whether the calling number (Digit) is entered, the call is terminated if the caller does not enter the calling number as a result of this check. In other words, the above process is a process for the caller to determine for himself / herself to display the calling number.

Next, as a result of checking whether the calling number is input in step S15, when the user inputs the calling number through the keypad, in step S16, the home location register performs call routing to the calling mobile communication switch and allocates the TLDN. And the confirmation sound. At this time, the called mobile communication exchange sets up the incoming call in step S17, and displays the calling party number on the called terminal during call alerting. In step S18, it is checked whether the incoming call is received from the called party's mobile terminal, and the service is controlled so that the call is made in the state where the called party is called. do. Here, the called party can see the calling number displayed on the display and press the call button to make a call. If the caller does not want to call, the caller can press the call end key to reject the call. That is, the called party subscriber can selectively make a call.

Figure 14 shows another embodiment of the method for controlling the calling number display according to the present invention.

This is a flowchart showing the Caller ID service function in call waiting.

As shown, if outgoing subscriber information is requested from the calling party control station to the visitor location registrar in step S21, the calling party mobile station call processing module notifies the outgoing subscriber information request to the visitor location registrar in step S22. When the mobile station call processing module requests call routing information to the home location register in step S23 (information request for call reception), the home location register in step S24 guides the call number input request for the Caller ID function to the mobile station call processing module. Deliver the broadcast. The mobile station call processing module, which receives the message, transmits a guide broadcast requesting the input of the calling number to the calling mobile terminal. Thereafter, it is checked whether the calling number (Digit) is input in step S25. If the caller does not enter the calling number as a result of the checking, the first call is maintained in step S26, and the third party subscriber is not called. In other words, the above process is a process for the caller to determine for himself / herself to display the calling number.

Next, as a result of checking whether the calling number is input in step S25, when the user inputs the calling number through the keypad, in step S27, the home location register performs call routing to the calling mobile communication switch and allocates the TLDN. And the confirmation sound. At this time, the called party mobile communication exchange sets up the incoming call in step S28, and displays the calling party number on the called terminal during call waiting tone transmission. In step S29, the terminal checks whether there is an incoming response from the called mobile terminal which has subscribed to the Caller ID service function, and controls the service to make a call when there is an incoming response from the called mobile terminal. In this case, the called party can see the caller ID displayed on the display and press the call button to make a call. If the caller does not want to call, the caller can reject the call. That is, the called party subscriber can selectively make a call. Next, in step S30, the caller ID service function subscriber makes a call with two subscribers through a send, and after the call ends, the call waiting function is terminated when the caller ID service function subscriber or another subscriber releases the call. do.

Figure 15 shows another embodiment of a caller ID display control method according to the present invention.

This is a flow chart showing the Caller ID service function during unconditional call forwarding (CFU).

As shown, if outgoing subscriber information is requested from the calling party control station to the visitor location registrar in step S41, the calling party mobile station call processing module notifies the outgoing subscriber information request to the visitor location registrar in step S42. If the mobile station call processing module requests call routing information to the home location register in step S43 (information request for call reception), in step S44, the home location register informs the mobile station call processing module of a call number input request for caller ID function. Deliver the broadcast. The mobile station call processing module, which receives the message, transmits a guide broadcast requesting the input of the calling number to the calling mobile terminal. Thereafter, it is checked whether a calling number (Digit) is input in step S45. If the caller does not enter the calling number as a result of the checking, the call is terminated. This is the process by which the caller decides for itself to display the calling number.

Next, as a result of checking whether the calling number is input in step S45, when the user inputs the calling number through the keypad, the call forwarding announcement broadcast is sent in step S46. In step S47, the home location register performs call routing to the calling mobile communication switch, allocates a TLDN, and transmits a confirmation tone. At this time, the called party mobile communication exchange sets up the incoming call in step S48, and displays the calling party number on the called terminal during call waiting tone transmission. In step S49, the terminal checks whether there is an incoming response from the called mobile terminal that has subscribed to the Caller ID service function, and controls the service to make a call when there is an incoming response from the called mobile terminal. In this case, the called party can see the caller ID displayed on the display and press the call button to make a call. If the caller does not want to call, the caller can reject the call. That is, the called party subscriber can selectively make a call. Next, in step S50, the caller ID service function subscriber makes a call with two subscribers through a send, and after the call ends, the call waiting function terminates when the caller ID service function subscriber or another subscriber releases the call. do.

As described above, the present invention, when a calling subscriber who has subscribed to the Caller ID service function makes a call, requests an input of a caller ID, and if the caller rejects the call, ends the call. By determining whether or not to display the calling number, there is an advantage that can solve the disadvantage that the unconditional display of the calling number generated in the existing CNIP to the called terminal.

In addition, the called party checks the caller ID displayed when the call waiting tone is transmitted, and if the call is desired, the call is pressed by pressing the call button, and when the caller does not want to call the call, the call is rejected by pressing the call end key. There is an advantage to facilitate the convenience to do.
