Method of Indicating Calling Number Identification Restriction-Overide}

The present invention relates to a method for displaying calling number priority, and in particular, each called member registered to a specific representative number by defining a network element that considers a calling number priority indication information field in a called subscriber's profile as an exchange or visitor registrant. The present invention relates to a caller ID priority display method for providing a caller ID priority display function.

In general, the IS-41 standard provides a calling number display service for displaying a calling party's calling party's calling party's calling party number in a mobile communication system.

Among the profiles related to all mobile subscribers, a calling feature indicator (CallingFeatureIndicator) includes a predetermined field related to whether caller ID is displayed.

If the mobile subscriber attempts to make a call, it is determined whether to display the calling number on the called mobile station according to whether the calling number display field in the corresponding call feature indicator is activated or deactivated.

That is, in the process of calling the calling subscriber (call setup) to a specific called party and ultimately alerting the called mobile station, the calling party's Calling Number Identification Restriction (CNIR) is deactivated. If the Calling Number Identification Presentation (CNIP) is activated, the calling party's number is displayed on the called mobile station. At this time, even if the calling party number prohibition information of the calling party is deactivated, if the calling party number display information of the called party is deactivated, the calling number is not displayed on the called mobile station.

If the calling party number prohibition information of the calling party is activated, the reason why the calling party number is not displayed on the called mobile station regardless of the calling party number display of the called party is that the calling party number prohibiting information takes precedence over the calling party number indicating information. to be. In addition, the calling feature indicator of all mobile subscribers includes a CNIR-Overide (CNIR-Overide) field, even if the caller ID prohibition information of the calling subscriber is activated. The reason why the calling party number is displayed to the called mobile station when the information is activated is that the calling party number priority indication information takes precedence over the calling party number prohibition information.

On the other hand, FA (Flexible Alerting), a representative service that supports multiple incoming calls among the services proposed in the IS-41 standard, provides a plurality of called member numbers to the home location register in relation to one assigned directory number. When a call is requested to the representative number by registering, each member's call is established at the same time. At this time, if any incoming member among the incoming members responds and the call to the called member is connected, the call to the remaining called member is released, and when the incoming call is requested to the representative number, the called members registered in the home location register Provide flexible incoming call service.

As such, in order to provide conditional calling number display service, the calling party's caller ID information and the calling party's calling party number are not displayed in the home location register where the called party is registered or the called exchange or visitor location register where the called party is currently roaming. It is necessary to decide whether to display the calling party number on the destination mobile station by combining the display information and the calling party number priority information together.In the IS-41 standard, the calling party number prohibition information of the calling party and the calling party number information of the called party must be determined. Although the subject to be considered is specified as the destination exchange, not the home location register, the subject which considers the calling party priority indication information of the called subscriber is not specified. Therefore, in selecting the subject that considers the calling number priority indication information among the home location register and the exchange, it depends on the software implementation method according to the system design.

On the other hand, for a one-to-one call, that is, a call between one calling subscriber and one called subscriber, the home location register and the called exchanger may consider the calling number priority indication information. That is, when the home location register becomes a subject for determining the calling number priority indication information, the calling party number digit in the process of including the calling party number digits (CallingPartyNumberDgts) received in the location request map operation in the calling party number string (CallingPartyNumberString). Even if the state of "Presentation Restricted" is set, the call party's numbering status is changed only when the caller ID priority information of the called party that is already built in the home location register is activated. Wood (Presentation Allowed) "to provide the calling party priority indication service of the called party. Also, since the called exchange also has the calling party priority information related to the called party in the visitor location register database, Conditional caller ID priority service It is possible.

However, in providing a multiple incoming service in which multiple calls must be set up simultaneously, such as FA service, when the subject considering the origination number priority indication information is a home location register, the originating number according to the location where each incoming member roams The display service may be enabled or disabled.

The reason for this is explained by dividing the following called member into a subscriber of the same mobile communication network as a subscriber of another mobile communication network.

First, if the called member is a subscriber of another mobile communication network, the home location register only transfers the called member's number to the calling exchange in the destination digits parameter of PSTNTermination. Subscriber profile information including caller ID priority indication information is unknown. Therefore, it is not necessary to consider the calling number priority indication information for the called member of the other mobile communication network.

If the called member is roaming to a different exchange from the originating subscriber, the calling party number digit is "Presented" in the process of including the calling party number digit received in the location request map operation in the calling party number string. Even if it is "listened", routing to the destination exchange by setting the status of the calling party number string to "presentation audible" only when the calling party priority indication information of the called member already established in the home location register is activated. RoutingRequestMAP operation is performed, and the destination exchange can determine whether to display the calling number by referring to the corresponding information.

That is, for a called member roaming to another exchange, an algorithm for considering the calling number priority indication information field for calling number display service in the home location register is required.

Unlike the incoming member roaming to another exchange that can perform the separate routing request map operation to transmit the calling number indication to the destination exchange, if the destination member is roaming to the same exchange as the calling subscriber, the location request ( LocationRequest) You must tell whether the calling number is displayed in the final result of the Map (Mobile Application Part: MAP) operation. However, among the parameters included in the result request map of the IS-41 standard, the TerminationList parameter (Local Termination / Intersystem Termination / PSTNTermination) including multiple destination information is merely used. There is only one calling party numberstring. If there is only one subscriber roaming to the same exchange as the calling subscriber among the called members, whether the home location register displays the calling party number for the called member in consideration of the calling party's calling number priority information on the calling party number string Can be passed. However, if there are at least two subscribers roaming to the same exchange as the calling subscriber among the called members, the home location register only considers one calling party number string parameter in consideration of each calling party priority indication information of these called members. There is a limit in that it is impossible to convey whether the calling number is displayed for each called member. That is, if at least two of the called members are roaming to the same exchange as the calling subscriber, it is impossible for the called member to consider the calling number priority indication information field for the calling number display service in the home location register. .

The present invention is to solve the general problems as described above, the purpose of the caller ID display prohibition information of the calling party and the caller ID display information of the called party as well as the caller ID display service provided by the mobile communication system For example, a caller who roams to a different exchange with a calling party in connection with a multi-call service that needs to be set up at the same time by defining a subject that compares and judges the calling number priority indication information to an exchange or a visitor register rather than a home location register. It is to provide conditional calling number display service not only to the member and the called member of other mobile communication network but also to the called member roaming on the same exchange as the calling subscriber.

Calling number priority display method of the present invention for achieving the above object, in the caller number priority display method for providing a caller number priority service for the incoming members registered in the representative number in the mobile communication system, Retrieving the profile of the calling subscriber from the visited subscriber register when there is a request from the subscriber to the representative number; Performing a location request map operation to a home location register in which a representative number is registered through the visited subscriber location register; Determining whether the called subscriber of the called member registered in the representative number is the called member roaming to the same exchange; When the called subscriber is a called member roaming to the same exchange, collecting called information by local termination; When the called subscriber is a called member roaming to another exchange, performing a routing request map operation to another exchange to collect incoming information by intersystem termination including TDL; Transmitting the collected incoming information to an originating exchange and simultaneously setting up a call to each destination member; When the call is set up, checking the profile of the called subscriber at the visitor location register or the called exchange to display the calling number first in the process of paging and alerting; Characterized in that it comprises a process of connecting a call for a multi-call service.

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

The present invention provides conditional calling number display service to all the called members by referring to each caller's priority information for a plurality of called members instead of only one called member in providing a multi-calling service such as FA service. For the purpose of providing, the subject considering the calling party number indication information of the called subscriber not specified in the IS-41 standard shall be defined as an exchange or visitor registrant, not a home location register.

As mentioned in the related art, in providing a caller ID service in a mobile communication system, caller ID display prohibition information of a calling party and caller ID priority display information of a called party not specified in the existing IS-41 standard. If the subject determining the home location register is at least two of the called members roaming to the same exchange as the calling subscriber, for each called member, the called number priority display field for the calling number display service is displayed. Consideration is impossible.

Therefore, it is prescribed that the subject that determines the calling party number prohibition information of the calling party and the calling party number indication information of the called party is not a home location register but an exchange or visitor subscriber. If the exchange or visitor registrant, not the home location register, considers the priority indication of the called party's calling party number, at least two of the called members, which is a problem that the home location registrar considers, are the same as the calling subscriber. Even if the roaming service is roaming, the home location register does not consider the calling number priority indication, so the calling party number digits of the calling party number digits in the initial location request map are included in the calling party number string and transmitted to the exchange.

As a result, since the profile information of the called member roaming to the same exchange of the calling subscriber is already established in the calling party subscriber register, the caller ID information of this common calling party number digit and the respective incoming call By determining the calling number indication and calling number priority indication information on the profile related to the member, the exchange can determine whether to display the final calling number and also display this information to each destination mobile station.

Calling number priority display method according to an embodiment of the present invention will be described with reference to the flowchart of FIG.

First, MIN1 (First Calling Member) with Caller ID Prohibition of Calling Subscriber Active and Caller ID registered with Representative Number (Pilot DN) is activated. Suppose there are and MIN2 (second incoming member).

When the incoming call is requested from the calling subscriber to the representative number (step S21), the calling exchange 10 checks the profile of the calling subscriber with the visitor register 20 (step S22) to confirm that the calling number prohibition information is activated. And the caller ID prohibition status is included in the CNIdigitsBCD as a "presentation listed".

The originating exchange 10 performs a location request map operation to the home location register 30 in which the representative number is registered through the visited subscriber location register 20 (step S23). Receiving this request, the home location register 30 recognizes that the called number is the representative number and starts collecting incoming information of the called members registered in the representative number.

It is determined whether the first called member MIN1 is roaming to the same exchange as the calling subscriber (step S24).

If the first destination member, MIN1, is roaming to the other exchange, the routing request map operation is performed to the other exchange (step S25), and the incoming information is transmitted to the intersystem termination including the Temporary Local Directory Number (TLDN). Collect (step S26).

At this time, the caller ID indication prohibition state received through CNIdigitsBCD in step S22 is included in the CNIdigitsASCII as it is.

However, if the first destination member, MIN1, is roaming to the same exchange as the calling subscriber, the destination information is collected using the multiple termination information (TerminationList) as local termination (step S27).

Thereafter, after the incoming information is collected in steps S26 and S27, it is determined whether there is another destination member, that is, another destination member other than MIN1 (step S28).

If there is no incoming member other than MIN1, the home location register transmits the incoming information collected in steps S26 and S27 to the termination exchanger 10 through the visited subscriber location register by including the information in the terminationList parameter (step S26). S29).

At the same time, if the call is set to each destination member (step S30), the calling party number is displayed in the process of paging and alerting by checking the field at the visitor location register or the destination exchange instead of the home location register. (Step S31). Then, the call is connected for the multi-call service (step S32).

Although the preferred embodiments of the present invention have been described in detail above, it will be understood by those skilled in the art that the present invention may be modified or modified in various ways. Therefore, changes of the embodiments of the present invention will not be able to escape the technical scope of the present invention.

As described above, the present invention compares and determines not only the calling party number display prohibition information of the calling party and the calling party number display information of the called party, but also the calling number priority display information in relation to the calling number display service provided by the mobile communication system. By defining the subject as an exchange or a visitor register rather than a home location register, as well as a receiving member roaming to a different exchange with a calling subscriber in connection with multiple incoming services that must be set up simultaneously, as well as receiving members of other mobile communication networks, It is possible to provide conditional calling number indication service to incoming members roaming to the same exchange as the calling subscriber.
