Abstract

PURPOSE: A mobile subscriber termination rejecting method is provided to reject a termination connection according to a location of a calling subscriber by use of a wireless intelligent network. CONSTITUTION: In a mobile subscriber termination rejecting method, a subscriber generates a dial digit using a mobile station(MS)(a), and the dial digit is transferred to an originating base station controller(BSC) of a corresponding region. The originating BSC transports a location request message(LOCREQ) comprising telephone number information to a home location register(HLR) related to the MS(b). The HLR adds and transfers an identification(ID) of a mobile switch center(MSC) in the location request message(locreq)(c). The originating MSC transfers to the SCP an analysis message(ANLZD) in which a trigger type parameter(TRIGRYPE), ID information of a serving MSC, telephone number information(DGTSDIAL) are comprised(d). The SCP detects a location of a calling subscriber using the MSC ID, and judges whether the detected location is a location registered to reject a termination. The SCP transfers the analysis message(ANLYZD), comprising information(RESUMEPIC) indicating the yes or no of a termination progress and the yes or no of a termination rejection, to the HLR(e), and the MSC senses a location trigger to apply a location request message(LOCREQ) having the parameter(TRIGTYPE) and the parameter(DGTSDIAL) to the HLR(f). The HLR transmits a routing request message(ROUTREQ) to a visited location register(VLR)(g). The VLR forwards the routing request message(ROUTREQ) to another MSC, and requests a temporary local directory number(TLDN)(h). A serving MSC transfers the TLDN, on which a routing request message(routreq) is loaded, to the VLR(i). The VLR again requests a routing request message(routreq) to the HLR(j), and the HLR transmits a location request message(locreq) to the originating MSC(k) with a termination list(TERMLIST) and a DMH direction switch displayer parameter(REDIND)(k).

Description

Mobile Call Rejection Method According to Location of Recipient Subscriber in Mobile Communication Network

The present invention relates to a mobile communication network, and more particularly, to a method for rejecting a mobile call according to a called subscriber location in a mobile communication network capable of processing a call according to a called subscriber location using wireless intelligent network technology.

With the development of communication technology, mobile communication is enabled. 1 shows a schematic diagram of such a mobile communication network.

In FIG. 1, reference numeral 1 denotes a mobile station (hereinafter, referred to as an MS) 1, and a subscriber may wirelessly connect to a network using the MS 1. The MS 1 may be used as the terminal itself, or may be used by connecting a personal computer or a fax.

The base station (hereinafter referred to as BS) 2 mediates the MS 1 and the Mobile Switch Center (hereinafter referred to as MSC) 3 and is largely referred to as a BTS (Base Tranceiver System; BTS). 21 and a base station controller (BSC) 22. Here, the BTS 21 is composed of one or more transceivers located in predetermined places to perform wireless communication with the MS 1. The BSC 22 exchanges messages with the BTS 21 and the MSC 3 as a device for controlling the BTSs 21.

The MSC 3 refers to an automated system that interfaces user communications from a wireless network to a wired or wireless network.

The Home Location Register (hereinafter referred to as HLR) 4 refers to a functional device that stores subscriber information (eg, electronic serial number, user file, current location) and manages mobile subscribers. . The HLR 4 may be located integrated with the MSC 3 or may be located independently of the MSC 3, and may serve a plurality of MSCs 3 as one HLR 4.

The Visited Location Register (hereinafter referred to as VLR) 5 is connected to one or more MSCs 3 and 6 and the user's HLR 4 when the subscriber is located within the area covered by the VLR. It refers to a functional device for storing subscriber information obtained from). When the mobile MS 1 enters a new service area encompassed by the MSC 3, the MSC 3 requests and reads information about the MS 1 from the HLR 4 so that the associated VLR 5 ).

The above-described apparatus is a schematic block diagram of a mobile communication network, and it can be easily understood by those skilled in the art that a general wired network or the like can be connected to the MSC 3.

An incoming call processing procedure in such a mobile communication network is shown in FIG. 2, which will be described in detail as follows.

First, a subscriber with an MS 1 generates a dial digit (such as a mobile number of a called party) using the MS 1, and this information is derived from the originating MSC 3 of the corresponding area. Is passed to (step a).

The originating MSC 3 sends a predetermined location request message LOCREQ to the HLR 4 associated with the MS 1, and the phone number information DGTSDIAL is included in the location request message LOCREQ (step b). Here, the relationship between the HLR 4 and the MS 1 is determined by the dialed receiving subscriber.

The HLR 4 transmits a routing request message ROUTREQ to the registered VLR 5 in which the receiver terminal is located according to the above-described information, and the mobile subscriber identity is identified in the routing request message ROUTREQ. A Mobile Ientification Number (MIN) is included (step c). Here, the called party identification number (MIN) means a unique number for identifying the called party.

The VLR 5 receiving the routing request message ROUTREQ sends this routing request message ROUTREQ to another MSC 6 (serving MSC) corresponding to the MIN, i.e., managing the location present at the mobile subscriber. Forward (step d).

The serving MSC 6 checks the state of the called party's terminal (corresponding to the MIN) according to this routing request message (ROUTREQ), and if possible, a Temporary Local Directory Number (TLDN) for the call. ) Is assigned to a routing request message (routreq) and transmitted to the VLR 5 (step e).

The VLR 5 sends this routing request message back to the HLR 4 (step f), and the HLR 4 sends a location request as a response to the location request message LOCREQ from the originating MSC 3. The message locreq is sent to the originating MSC 3 together with the terminator list and the DMH redirection indicator (REDIND) parameters (step g).

Here, the terminating terminal list (TERMLIST) is a list of the terminating stations when routing to the serving MSC 6, that is, whether it is a local termination, an intersystem termination, or a PSTN termination with a wired network. Information that displays.

The DMH redirection indicator (REDIND) stands for DMH_Redirection Indicator, and DMH stands for Data Messaging Handler. This parameter refers to a parameter that is used to simply receive the incoming call to the mobile destination terminal and not to stop the operation, but to expand and process the incoming call in accordance with the state of the terminal.

The originating MSC 3 makes a call request to the serving MSC 6 using an interconnection protocol such as SS7 according to the parameters of this location request message (locreq) (step h).

On the other hand, the above description is a case of inter-country calls, and in the case of a domestic call, when the HLR 4 receives a location request message (LOCREQ) from the originating MSC 3, the HLR 4 determines that the call to the called party is a domestic call. Then, the destination station list (TERMLIST), that is, a local termination parameter, is put in the location request message (locreq) and transmitted to the originating MSC (3).

As can be seen from the above description, it can be seen that in the conventional incoming call processing procedure, the incoming call processing to the called subscriber is performed by the call request from the calling subscriber.

On the other hand, unlike a wired communication network, a mobile communication network may frequently move to a subscriber. Accordingly, when a subscriber moves to a specific region, there is a case where a subscriber wants to reject telephone and data communication from a caller. In such a case, there is an increasing need for services or operators that are not necessary for the general public, and those who have a lot of external activities. However, in the conventional incoming call processing method, there is a problem in that it is not possible to automatically reject the request according to the location of the subscriber as described above.

In order to solve this problem, the same applicant as the present applicant filed a "mobile call rejection method according to the called subscriber location in the mobile communication network (application number No.)". However, in the present invention, only the intelligent network function of the service control point (SCP) connected to the HLR is used, which causes a problem that the processing procedure is complicated. The present inventors conceived that while trying to solve this problem, the intelligent network function can be given to the conventional MSC, and in this case, the incoming call processing for the input call can be simplified.

The present invention has been made in accordance with the above-described idea, and an object of the present invention is to provide a mobile call according to a called subscriber location in a mobile communication network, which can simply and automatically reject a call connection according to the called party's location using a wireless intelligent network. To provide a method of rejection.

In order to achieve the above object, the present invention distinguishes a call between a local call, an inter-office call, and a wired network according to a called party's location stored in a home location register (hereinafter referred to as an HLR) to receive an incoming call to a called subscriber. In the mobile communication network performing the incoming / outgoing call process, a service control point (SCP) configured to store and request a call connection rejection according to the subscriber's location according to the subscriber's request is configured, and the mobile switch center (Mobile Switch) A mobile call screening method according to a called party's location of a mobile communication network configured to support an intelligent network protocol in a center (hereinafter referred to as MSC). The originating MSC corresponds to a telephone number corresponding to a dial digit of a mobile station (hereinafter referred to as MS). Possible to process trigger that informs functions that can be processed by information (DGTSDIAL) parameter and location trigger (T RANSCAP) parameter and a WIN Capability (WINCAP) parameter indicating that the intelligent network processing is possible to transmit to the HLR by including in a predetermined location request message (LOCREQ); The HLR sends a location request message (locreq) having a trigger address list (TRIGADDRLIST) for the location trigger, the ID of the serving MSC and the address for the SCP to the originating MSC in response to the location request message (LOCREQ) from the originating MSC. Steps; Initiating MSC includes the trigger type parameter (TRIGTYPE) and serving MSC ID information indicating that the location trigger is detected according to the trigger address list (TRIGADDRLIST) in the analysis message (ANLYZD) to transmit to the SCP; SCP analyzes the MSC ID information and delivers it to the originating MSC through an analysis message (anlyzd) containing information indicating whether the call proceeds and whether the call is rejected according to the location of the called subscriber; The originating MSC stops all processes when the information in the analysis message (anlyzd) message is call rejection information.In the case of call progress information, the MSC classifies the call based on the called party's location according to the called party. It proceeds to the incoming process of the incoming call to the called subscriber.

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

First, the present invention uses a wireless intelligent network (WIN) technology in which the technology of an intelligent network used in a general wired communication network is applied to a wireless network.

That is, a service control point (hereinafter referred to as SCP) 7 is further configured in the structure of the conventional mobile communication network as shown in FIG. 3, and this SCP 7 is connected to the HLR 4. And selectively connects calls according to the called party's position with respect to the incoming call. It will be readily understood by those skilled in the art that the rejection of call connection according to the subscriber's location should be stored in advance in the SCP 7 according to the subscriber's request. In addition, the MSC (3) of the present invention is configured to perform an intelligent network protocol support function, it is possible to process the incoming call to be described later due to this function.

Other components except for the SCP 7 and the MSC 3 in FIG. 3 are the same as those in the conventional mobile communication network, and thus description thereof is omitted.

An incoming call processing procedure in the mobile communication network configured as described above is shown in FIG.

The subscriber with the MS 1 generates a dial digit (mobile recipient's phone number) using the MS 1, and this information is passed to the originating MSC 3 in that area ( Step a).

The originating MSC 3 has an intelligent network function as described above, and thus can process triggers according to the trigger address list (TriggerAddressList) provided from the HLR 4. That is, the HLR 4 provides a list of triggers to be processed by the MSC 3 as described below, and provides an address of a network entity providing a service control function for each trigger.

The MSC 3 sends a predetermined location request message LOCREQ to the HLR 4 associated with the MS 1 in response to the above-mentioned dial digit of the MS 1, and the phone number information is included in the location request message LOCREQ. (DGTSDIAL), send a trigger processable parameter (TRANSCAP) and a WIN processable parameter (WINCAP) to the HLR 4 (step b) informing the functions processable by the triggers, where the HLR 4 and the MS ( The association with 1) is determined by the dialed receiving subscriber. In addition, the Trigger Capability (TRANSCAP) parameter specifies functions that can be processed according to the Trigger Address List (TriggerAddressList) from the HLR 4, and in order to implement the present invention, the location within the Trigger Capability Parameter (TRANSCAP) is performed. It should be indicated that support for (location) triggers is available. This location trigger means a function that the MSC 3 can reject for a call as described below. In addition, the WIN process capable parameter (WINCAP) should specify that the MSC 3 can process the intelligent network.

The HLR 4 must respond to a location request message (LOCREQ) from the MSC 3, where the WIN processable parameter (WINCAP) and the trigger processable parameter (TRANSCAP) have been provided from the MSC (3). The location request message (locreq) is transmitted to the MSC 3 by adding the trigger address list (TRIGADDRLIST) for processing by (3) and the ID of the MSC 6 managing the location of the called subscriber (step c). ). On the other hand, in the present invention, the HLR 4 is provided with a trigger processable parameter (TRANSCAP) capable of processing a WIN processable parameter (WINCAP) and a location trigger from the MSC (3). Trigger Address List and Serving MSC IDs for Advanced Termination triggers to know call processing, inter-station processing and incoming call to wired network, and location triggers for call rejection features of the present invention; In this case, the network element for processing the location trigger, that is, the address for the SCP (7) is transmitted to the MSC (3).

The originating MSC (3) includes the trigger type parameter (TRIGTYPE), serving MSC ID information, and telephone number information (DGTSDIAL) in the analysis (ANLZD) message, indicating which triggers have been detected according to the trigger address list (TriggerAddressList). Send to SCP 7 (step d).

SCP (7) analyzes the MSC ID information to detect the location of the called party, and judges using the stored subscriber file whether the location of the called party is the location to which the call is requested.

SCP 7 sends this determination result to MSC 3, an analysis message (anlyzd) containing information (RESUMEPIC) indicating whether the call proceeds and whether the call is rejected (step e). If the information in the analysis message is call reject information, the MSC 3 stops the call connection attempt by the called party by stopping all processes, but if the analysis message information is call progress information, The process of is performed sequentially.

That is, the MSC 3 senses the location trigger and applies this trigger type parameter (TRIGTYPE) and the telephone number information parameter (DGTSDIAL) to the HLR 4 by including it in the position request message (LOCREQ) (step f).

The HLR 4 transmits a routing request message ROUTREQ to the registered VLR 5 where the receiver terminal is located according to the above-described information (step g), and within the mobile caller identification number Mobile Ientification Number; MIN) is transmitted. Here, MIN means a unique number for distinguishing a called party.

By means of the routing request message ROUTREQ, the VLR 5 forwards this routing request message ROUTREQ to another MSC 6 (serving MSC) that manages the location corresponding to the MIN, i. E. forwarding to request a Temporary Local Directory Number (TLDN) (step h).

The serving MSC 6 loads the temporary location telephone number (TLDN) into the routing request route (routreq) and sends it to the VLR 5 (step i), and the VLR 5 sends this routing request message (routreq) back to the HLR. Transfer to step (4) (step j). The HLR 4 sends the location request message locreq together with the endpoint list TERMLIST and DMH redirection indicator parameters in response to the location request message LOCREQ from the originating MSC 3. (Step k). Initiating MSC 3 attempts to establish a call to serving MSC () according to the parameters of this location request message (locreq) (step l).

The incoming process of FIG. 4 shows a case of an inter-Korean call, and in the case of a local call, steps (f-1) are omitted.

As can be seen from the above description, in the present invention, while configuring the SCP (7) performing the intelligent network function, while the originating MSC (3) is also configured to perform the intelligent network, the MSC (3) is subjectively SCP (7) Ask SCP (7) to determine whether to set up a call for an incoming call, and SCP (7) notifies the originating MSC (3) of the call establishment or rejection of the called party's location. If the notification result is a call rejection, the originating MSC (3) abandons the call setup for the input call by stopping all processes, but if the notification result is the call setup, it sets up the input call to the called party through the same procedure as before. Is to try.

Therefore, according to the present invention, when the subscriber moves to a predetermined position, that is, the requested position, the call connection attempt is automatically abandoned, thereby increasing the convenience of the subscriber.
