Abstract

PURPOSE:To efficiently implement the allocation of applied service (customization) of service to be applied while covering a wide area by eliminating the need for the customization as relation of correspondence between identification information of each subscriber and identification information of the service to be applied for each customization. CONSTITUTION:In the case of implementing the customization, a standard area/ applied service relevant storage means 2 is to be built up as the relation between identification information 6 of the standard area and identification information 7 of the applied service. When the service to be applied is decided based on a call from each subscriber, geometrical discontinuity of the identification information 5 of each subscriber is absorbed by a subscriber/standard area relevant storage means 1. Then after the identification information 5 of the subscriber is converted into the identification information 6 of the standard area, the identification information 7 of the service to be applied is obtained via the identification information 6 of the standard area. Thus, while a board area is being covered, the customization of the service to be applied is efficiently implemented.

Description

[Detailed Description of the Invention] [Summary] The present invention relates to a service control method that changes the service to be applied corresponding to the number when a call is made to a specific number, depending on the calling area, and further For details, refer to the calling area identification method that identifies the calling area of a caller from the caller number.It enables efficient registration of applicable services by calling area and high-speed search for applicable services by calling area. For the purpose of subscriber/standard area correspondence storage means for storing the correspondence relationship between the identification information of the subscriber and the identification information of the standard area; A standard region/applicable service correspondence storage means stores the correspondence relation with service identification information, and when a call is received from a subscriber, the standard region in which the subscriber is included is stored. A first control means obtains by indexing a subscriber/standard region correspondence storage means with identification information of the standard, and determines which applicable service corresponds to the standard region indexed by the first control means. a second control means that obtains by indexing the standard region/applied service correspondence storage means with region identification information and selects the applied service corresponding to the indexed application service identification information as the service to be executed; It is configured to have the following.

(Industrial Application Field) The present invention relates to a service control method for changing a service to be applied to a specific number depending on the calling area when a call is made to a specific number, and furthermore, More specifically, the present invention relates to a calling area identification method for identifying the calling area of a caller from a caller number.

[Prior Art] When a call is made to a specific telephone number (hereinafter referred to as a telephone number) in a telephone network, the service that should be applied to that telephone number is determined depending on the calling area. Modifications have been made to run that service. Specifically, for example, the destination of the call may be changed depending on the calling area.

Such service control requires technology to identify the calling area, and the first conventional example for this purpose is to register the upper few digits of the caller's telephone number (hereinafter referred to as the "all telephone number"). There is a known method for defining services to be applied to registered data. For example, individual services may be defined for each area code.

As a second conventional example, there is a wild card method in which characters are assigned in place of numbers during registration, and the characters are used to represent multiple numbers.

For example, the registered content '44*J is r440J~'4
It means 49J.

[Problem to be solved by the invention]

However, in the case of the above-mentioned first conventional example, in order to register all the area codes (station code, code code, etc.) in the service control station, a large amount of memory is required1.
It takes a lot of time to search for codes, which affects serviceability (cost, response time, etc.). For this reason,
It is necessary to limit the number of codes that can be registered to about 10, and there is a problem that the application area of the service is geographically limited.

On the other hand, in the above-mentioned second conventional example, a service with a small amount of memory and high search efficiency can be achieved within the range where the geographical location of the transmission area matches the station code and area code. can. However, in reality, the above-mentioned correspondence does not necessarily match, and there are many cases where the area number of an adjacent area that is very close to yours is different from your own area number. In such a case, the second conventional example cannot be used, and in the end, telephone numbers must be registered individually using the method according to the first conventional example, which increases the number of registrations. There is a problem with this. This problem will be specifically explained using FIGS. 8 and 9.

FIG. 8 is an explanatory diagram of the case where a call is made to a specific telephone number from each caller T1 to T7 and the call is routed to each callee A, B, and C.

Now, the station code is r201. Caller (T1), r211
．． Assume that a call from a caller (T2) is registered to be received by a called party A. In this case, it is sufficient to register with the wild card "r2*1", which changes the station code from r201J to r291. All calls from callers up to this point are received by callee A.

On the other hand, the caller of station court "2o3" (T.

etc.), the call is received by recipient B, but the station code is ``205J''.
The caller of ``T4'', the caller of r215J (T6), the caller of station code r309J (T,), and the caller of ``329'' (T,) are called callee B depending on the geography within the area.
Or suppose that you want C to receive calls selectively. In this case,
Wild cards such as "2*5" and "r3*9" cannot be used, and in the end, it is necessary to register in a format with a large amount of information (number of digits) as shown in the registration table in Figure 9. First, a large amount of memory is required to store the registration table. In addition, since this process is a search-type process, as the amount of data increases, the average search time increases, and the maximum search time increases in a geometric progression, degrading the service quality for subscribers. There is a big possibility.

The problems listed above are not limited to telephone networks;
Intelligent m such as l5DN that is expected to become popular in the future
A similar problem may occur in services that correspond to each terminal in .

SUMMARY OF THE INVENTION An object of the present invention is to efficiently register applicable services by region of origin and enable high-speed search of applicable services by region of origin.

(Means for Solving the Problems) First, the present invention is based on a service control method in which when a call is made to a predetermined number, the applicable service is changed depending on the calling area in response to that number. do.

First of all, the service area in the telephone network etc. is as follows.
Geographically divided into multiple standard regions.

This standard area may include multiple station codes in a telephone network or the like.

Next, under the network configuration as described above, a service control station that performs service control has means configured as shown in FIG. 1.

First, a subscriber/standard area correspondence storage means stores which standard area each subscriber in the service target area is included in as a correspondence between the subscriber's identification information 5 and the standard area identification information 6. It has l.

The means may include, for example, a RAM or the like that stores a correspondence table in which the upper predetermined digits of all telephone numbers of the subscriber are used as the subscriber's identification information 5, and the standard area with a serial number is set as the standard area identification information 6. It is. Note that the above-mentioned number of digits can be varied within a range that allows the subscriber to be identified.

Next, determine which applicable services each standard region corresponds to.
Identification information 6 for each standard area and identification information 7 for applicable services
It has a standard area/applicable service correspondence storage means 2 that stores the correspondence relationship with the standard region/applied service correspondence relationship.

The means stores, for example, a RAM that stores a correspondence table in which a serial number is attached to an applied service as applied service identification information 7, and this corresponds to the above-mentioned standard area identification information 6.
etc.

Furthermore, when a call is received from a subscriber, which standard area the subscriber is included in can be determined by indexing the subscriber/standard area correspondence storage means 1 using the identification information 5 of the subscriber. It has a first control means 3 for determining.

In addition, determining which applied service the standard area indexed by the first control means 3 corresponds to is determined by indexing the standard area/applied service correspondence storage means 2 with the identification information 6 of the standard area; It has a second control means 4 that selects the application service corresponding to the indexed application service identification information 7 as the service to be executed.

[For production]

In the present invention, the standard for reclassifying the applicable services is a standard area unit that geographically categorizes the service target area, and when assigning (customizing) applicable services, standard area identification information 6 Standard area/
The applied service correspondence storage means 2 may be constructed. When determining the service to be applied based on the call from each subscriber, the geographical discontinuity of the subscriber identification information 5 is absorbed by the subscriber/standard area correspondence storage means 1, Subscriber identification information 5 is standard area identification information 6
After the standard area identification information 6 is converted into , the identification information 7 of the service to be applied is determined via the identification information 6 of the standard area.

Therefore, it is no longer necessary to customize the correspondence between the identification information 5 of each subscriber and the identification information 7 of the service to be applied for each customization, so the amount of memory required at this stage can be significantly reduced. It is possible to efficiently customize the services to be applied while covering a wide area.

On the other hand, the correspondence between the subscriber identification information 5 and the standard area identification information 6 in the subscriber/standard area correspondence storage means 1 is as follows:
Since it is only necessary to have one memory in the service control station, the amount of memory required at this stage is not very large.

Further, in the present invention, the subscriber/standard region correspondence storage means 1 is indexed by the subscriber identification information 5, and the standard region/applied service correspondence storage means 2 is indexed by the standard region identification information 6 determined thereby. Then, the identification information 7 of the service to be applied is obtained. Since the service to be applied is determined based on the call from each subscriber through step-by-step Intel Nox operations, service control processing can be executed at high speed.

〔Example〕 Hereinafter, the present invention will be described in detail with reference to the drawings.

First, FIG. 2 is a diagram showing an example of the configuration of a network to which an embodiment of the present invention is applied.

As shown in the figure, each subscriber 8 has a local station 9 (SS P

o1nt). Each 5SP9 is S S 7
(Signaling System No.

7) Belonging to the network 10, and also in the 5S7t network 10, there is a service control station 11 (SCP 11) that controls various services.
ntrolPoint ) is connected. The part that is particularly relevant to the present invention is 5CPII.

Next, the configuration of 5CPII is shown in FIG.

The signal path 16 is SS? in FIG. This is a trunk line connected to the network 10.

The signal path control device 14 is the SS7 network 1 in FIG.
The message including the service access code and power generation number sent from each 5SP9 via 0 is extracted and sent to the central processing unit 12.

The communication path switch 15 performs switching connection of the communication path 16.

The central processing unit 12 performs service control processing particularly related to the present invention.

The storage device 13 is a SAN, which will be described later and is particularly relevant to the present invention.
Table 16, CAN table 17 and routing
Store table 18.

The present invention is characterized by the operation of service control processing in the central processing unit 12 shown in FIG.

The operation of the embodiment having the above configuration will be described below. In this embodiment, when any of the subscribers 8 in FIG. 2 makes a call to a specific telephone number, 5CPII in FIG. The Freephone service is taken as an example in which the call destination (routing destination) is determined according to the calling area of the subscriber 8 who made the call.

First, in this embodiment, the concept of standard area is introduced. The standard area refers to an area obtained by geographically dividing the divided area as shown in FIG. 8 into further geographical areas as shown in FIG. 4, for example. Then, assign a serial number to each standard region,
This number is the standard area number (SAN: 5tand
ard Area Number (hereinafter the same). As a result, each subscriber 8 in FIG. 2 is always associated with one SAN. The relationship between each originating subscriber TI-T and each terminating subscriber A, B, and C in FIG. 4 is the same as that in FIG. 8.

In this embodiment, first, a table called a SAN table is prepared in the storage device I3 shown in FIG. This table is as shown in Figure 7 for each subscriber 8 in Figure 2.
This is a table in which the SAN corresponding to the subscriber can be found using the station code of each subscriber as an index (address to be accessed).

Next, in this embodiment, when determining (customizing) the routing destination, instead of using the station data from each subscriber 8,
This is done using SAN as a unit. That is, as shown in FIG. 5, for example, 5ANI to 5AN21 are grouped into routing destinations represented by destinations A, B, and C, and each group is assigned a serial number such as 1 to 3. This number is called CAN (Cusjormized Area Nuln).
ber). A table called a CAN table is prepared in the storage device 13 of FIG. 3 as a table corresponding to FIG. 5. This table is shown in Figure 71.
7 (in Figure 5, each CAN (CANI-CAM3
) for each SAN (5ANI to 5AN21 in Figure 5)
This is a table that can be used as an index.

Furthermore, in this embodiment, a table called a routing table is prepared in the storage device 13 shown in FIG. This table, as shown in Fig. 7 18, shows each CAM (C
This is a table in which the telephone numbers of routing destinations (A, B, and C in FIG. 5) that correspond one-to-one to AN1 to CAN3) can be found using each CAN as an index.

5CP in Figure 2 or Figure 3 based on the above data structure
Regarding the operation of the routing destination determination process in II,
This will be explained below.

FIG. 7 shows the storage device 1 of 5CPII in FIG. 2 or 3.
4 is an operation flowchart of a routing destination determination process executed by the central processing unit 12 of FIG. 3 by a control program (not shown) in FIG. 3;

First, in Sl, which of the subscribers 8 in FIG.
5SP9, SS7 non-sotower lO (Figure 3) and channel monitoring words! 14 (FIG. 3), a call is received to inquire about a service. This received data includes a service access code from the 5SP9 that indicates the content of service control, and all telephone numbers of the originating subscriber.

Next, in S2, processing for recognizing the service to be applied is executed. As a result, it is recognized that the Freephone service is requested, and the process moves to S3.

In S3, all telephone numbers of calling subscribers are read from the received data.

Subsequently, in S4, lower unnecessary digits are masked.

With all the telephone numbers (station codes) masked in this way, the SAN table 6 in the storage device ff1lU is indexed as shown in FIG.
A and N are read out.

Next, in S6, CAN table 1 corresponding to the called number is created.
7 is read out from the storage device 13, and in S7, the sixth
As shown in FIG. 20, the CAN table 17 is indexed with the SAN read from the SAN table I6. This causes the corresponding CAM to be read.

Further, in S8, the routing table 18 corresponding to all telephone numbers is read out from the storage device 13, and in S9,
As shown in FIG. 6, the routing table 18 is indexed by the CAN read from the CAN table 17, and the corresponding routing destination is determined.

By the above-described operation, for example, in FIG. 4, subscriber T
When a call is made from , the T4 station code calls S.
The AN table 16 is indexed to find 5ANII, the CAN table 17 is found by the called number, and CAM2 is found by indexing by 5ANII. Then, CAM2 creates routing table 1.
8 is indexed to find the routing destination B (
(See Figure 5 above).

As shown above, when determining the routing destination based on calls from each subscriber 8 in FIG. 8) is the state in which the SAN table 16

is found.

Therefore, it is no longer necessary to customize the correspondence between the station code of each subscriber 8 and the service to be applied, not only when determining the routing destination but also every time the service to be applied is customized. In other words, since it is only necessary to customize the CAN table 17 that shows the correspondence between each SAN and CAN, the amount of memory required at this stage can be significantly reduced, and the required services can be adjusted while covering a wide area. Customization can be done efficiently.

On the other hand, the correspondence between the station code of each subscriber 8 and each SAN in the SAN table 16 is fixed in 5CPII.
Since it is only necessary to have i, the amount of memory required at this stage does not increase.

In addition, in this embodiment, the SA at the station court of subscriber 8 is
The N table 16 is indexed, the CAM table 17 is indexed with the resulting S A N to determine the CAN, and the routing table 18 is further indexed using this CAN to determine the routing destination. In this way, since the routing destination is determined based on the call originating from each subscriber 8 through stepwise index operations, service control processing can be executed at high speed.

In addition, in this embodiment, an example of processing for determining a routing destination based on the originating area based on S A and N is shown, but in addition to this, it is also possible to vary the routing probability to multiple routing destinations depending on the originating area based on the SAN. It can be applied to a variety of services, such as a service that changes the routing route depending on the originating area based on S A and N.

Furthermore, in this embodiment, standard region division is performed uniquely and one type of SAN table is provided in the storage device 13 shown in FIG. 3, but different standard region divisions may be performed depending on requested service control. , a selection may be made from multiple types of SAN tables.

Furthermore, for special calls that cannot be covered by standard area division, registration similar to the conventional example described above may be allowed and combined with the present invention.

[Effects of the Invention] According to the present invention, there is no need to perform customization as a correspondence between the identification information of each subscriber and the identification information of the service to be applied for each customization, so the amount of memory required at this stage can be significantly reduced. This makes it possible to efficiently customize services to be applied while covering a wide area.

In addition, the correspondence between the subscriber identification information and the standard area identification information in the subscriber/standard area correspondence storage means only needs to be stored in the service control station by 1'Mi, so the amount of memory required for the second stage is This has the effect that the amount is not so large.

Furthermore, in the present invention, the service to be applied is determined based on the call from each subscriber through stepwise index operation, so that service control processing can be executed at high speed.
