Abstract

PURPOSE:To attain a switching processing at a high speed by accumulating the subscriber information in a main storage for each switching service time band and referring to the subscriber information through the main storage only. CONSTITUTION:When a terminal 1 calls a terminal 2, a call request is sent to a call control part 4 from the terminal 1 via a switching processing part 3. The part 4 verifies whether the call of the terminal 1 should be accepted or not. For this purpose, the subscriber information stored in a main storage part 9 is referred to through a subscriber information control part 5 as the verification of the terminal 1. If the part 9 stores the subscriber information and also the present information, the part 5 sends the acceptance permission to the part 4 for the call request of the terminal 1. In regard of reference to the subscriber information, only the part 9 is retrieved. The quantity of information stored in the part 9 is small since the information on the switching subject time band only is stored in the part 9. Therefore the time needed for reference to the subscriber information is shortened. In the same way, the terminal 2 also requires the retrieval of the part 9 only like the terminal 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber information control system for a subscriber of a switching system.

[0002]

2. Description of the Related Art As one form of sophistication of exchange services,
Personal communication services are receiving attention. Personal communication is communication that respects the will of the sender and the receiver.
Typical services are "screening" that distinguishes connection partners and "scheduling" that specifies connection time. When subscribers of the exchange system enjoy services such as "screening" and "scheduling" relating to call origination / termination regulations, it is necessary to register such call origination / termination regulation information as subscriber information in the exchange system. Call control information is registered in the exchange system on a subscriber basis,
When the number of subscribers is large or the data amount of registered outgoing / incoming call regulation information is large, the data amount of subscriber information in the entire switching system becomes enormous. As a method of controlling this enormous amount of subscriber information, there is a "subscriber data management method" (Japanese Patent Laid-Open No. 3-203448). This is because two storage devices, a main storage device and an external storage device, are provided as storage devices for subscriber information, and when the subscriber information is referred to, it is extracted from the main storage device if it is stored in the main storage device. If not stored, the reference time after the second time is shortened by extracting from the external storage device and storing it in the main storage device.

[0003]

However, in the above-mentioned conventional method, the subscriber information can be referred to at high speed if the subscriber information is in the main storage device, but if the subscriber information is not in the main storage device, the external storage device can be used. The search time and the transfer time from the external storage device to the main storage device are longer than those in the main storage device, so it takes much time to refer to the subscriber information, resulting in a long call connection time. It had a problem that

Further, when the subscriber information has a large amount of data to be transferred from the external storage device to the main storage device at the time of referring to the subscriber information, the storage capacity of the main storage device becomes large. Was there.

Further, there is a problem that the storage capacity of the main storage device becomes insufficient, and the processing becomes complicated when new subscriber information cannot be set in the main storage device.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and an object thereof is to provide a subscriber information control system in which the reference time of subscriber information is short and the storage capacity of the main memory is small.

[0007]

In order to achieve this object, the subscriber information control system of the present invention is a time period for dividing a service providing time of a switching service into a plurality of time zones and setting a demarcation time of the time zones. Band setting means, external storage means for storing the subscriber information of all subscribers, and information for indicating the temporal enjoyment of the exchange service of the subscriber information stored in the external storage means, exchanged to the time zone Extraction means for extracting subscriber information to be serviced, main storage means for accumulating subscriber information of the subscriber extracted by the extraction means, and for each delimiter time set in the time zone setting means And a means for updating the contents of the subscriber information in the main storage means.

[0008]

With this configuration, the service providing time of the exchange service is divided into a plurality of time zones, and the subscriber who is the target of the exchange service in the specific time zone uses the time-based call restriction information of the subscriber information as a search key. By extracting the subscriber information and the subscriber information from the external storage, the subscriber information in a specific time zone can be stored in the main storage.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 and 2 are terminals, 3 is an exchange processing unit, 4 is a call control unit, 5 is a subscriber information management unit, 6 is a time zone setting unit, 7 is an external storage unit, and 8 is an extraction unit. , 9 are main storage units.

The information that sets the subscriber's schedule is
After being transferred from the terminal 1 or the terminal 2 or the like to the external storage unit 7 via the subscriber information management unit 5, it is stored. However, the subscriber information is already stored in the external storage unit in order to simplify the following explanation of the operation. It shall be set to 7. In addition, the external storage unit 7
The number of subscriber information stored in is 3 for simplification.

FIG. 2 shows the contents of the subscriber information set in the external storage unit 7. In FIG. 2, (a) shows the contents of the subscriber information 20. The contents of the subscriber information 20 are 1 from 8:00
He is absent until 2 pm and is present from 12:00 to 18:00. If you are absent, you are not subject to the exchange service, and if you are present, you are subject to the exchange service. Therefore, in the subscriber information 20, the exchange service is from 12:00 to 18:00. The contents of the subscriber information 30 are shown in (b). Since the subscriber information 30 is absent from 8:00 to 18:00, the exchange service is not subject to this period.
The content of the subscriber information 40 is shown in (c). Subscriber information 40
Is available from 8:00 to 10:00, is absent from 10:00 to 12:00, is present from 12:00 to 15:00, and is absent from 15:00 to 18:00. They are 8:00 to 10:00 and 12:00 to 15:00.

The operation of the embodiment will be described below.
When the exchange service time is divided into a plurality of time zones, the delimiter time is set in advance in the time zone setting section 6 by the operator of the exchange system. For example, as shown in FIG. 4, when the daily exchange service is divided into 2 hours from 8:00 to 18:00, the main storage unit 9 is updated 6 times a day. The activation of the update is output from the time zone setting unit 6. The content of the update activation information output from the time zone setting unit 6 to the subscriber information management unit 5 is information on the time zone of the exchange service. 14
When updating the subscriber information in the time zone of the exchange service from 14:00 to 16:00, the time zone setting unit 6 displays "14:00 to 16:00".
Information having the content of "time" is output to the subscriber information management unit 5. In the subscriber information management 5, the extraction unit 8 displays “from 14:00 to 16
Outputs information with the contents of "time". In the extraction unit 8, “14
The subscriber information set in the external storage unit 7 is searched by using the information indicating the time zone of the exchange service from "16:00 to 16:00" as the search key information, and the subscriber who is the target of the exchange service during the exchange service time zone. Person information. 2 (a),
When the three subscriber information items (b) and (c) are set in the external storage unit 7, the search unit 81 copies the subscriber information for each subscriber from the external storage unit 6. After that, the subscriber information extraction unit 82 selects the exchange service time zone from “14:00 to 16
By "time", it is determined whether the subscriber information is to be exchanged. When the target of the exchange service, the subscriber information is extracted only during the exchange service time zone, and the subscriber information is not extracted unless the target of the exchange service. Subscriber information 20
Since the user is present from 14:00 to 16:00, the subscriber information from 14:00 to 16:00 is extracted. The extracted subscriber information is shown in FIG. Subsequently, the subscriber information 30 existing in the external storage unit 7 is copied from the external storage unit 7 by the search unit 81, and the information of the exchange service time zone is extracted by the subscriber information extraction unit 82. In this case, since 14:00 to 16:00 is absent, the subscriber information is not extracted. Subsequently, the search unit 81 copies the information of the subscriber information 40 from the external storage unit 7, and extracts the subscriber information of the exchange service time zone. In the subscriber information 40, 14:00 to 15:00 are present, and 15:00 to 16:00 are absent. Therefore, the subscriber information extracting section 82 extracts the subscriber information from 14:00 to 15:00 when the user is present. This extracted subscriber information is shown in FIG.
It shows in (b).

In this way, all the subscriber information stored in the external storage unit 7 is extracted during the exchange service time zone.

The amount of subscriber information (see FIG. 3) extracted by the subscriber information extracting unit 82 is considerably smaller than the amount of information stored in the external storage unit 7 (see FIG. 2). .

At the break time of the exchange service set in the time zone setting section 6, the time zone setting section 6 issues an update request to the subscriber information management section 5 to update the contents of the main storage section 9. Output. In response to this update request, the subscriber information management unit 5 outputs an instruction to the extraction unit 8 to transfer the subscriber information subject to the exchange service to the main storage unit 9 during the exchange service time period, and the extraction unit 8 outputs the main information. The extracted subscriber information is transferred to the storage unit 9.

The operation will be described below by taking a call connection as an example. When a call is made from the terminal 1 to the terminal 2, a call request is transferred from the terminal 1 to the call control unit 4 via the exchange processing unit 3. The call control unit 4 requests the subscriber information management unit 5 to verify the terminal 1 in order to verify whether or not the call from the terminal 1 is accepted. The subscriber information management unit 5 refers to the subscriber information of the main storage unit 9 in order to verify the subscriber information of the terminal 1. If there is subscriber information in the main storage unit 9 and the presence information is set, the calling request of the terminal 1 is accepted and permission is output from the subscriber information management unit 5 to the call control unit 4. To refer to the subscriber information, only the main memory needs to be searched. Also,
Since the information stored in the main memory is only for the exchange target time period, the amount of information is small. Therefore, the time required to refer to this subscriber information is short. Terminal 2 which is the terminal to be called next
Verify subscriber information in. As with the terminal 1, the terminal 2 only needs to search the main storage unit 9, so that verification can be performed at high speed.
When the verification of the subscriber information of the terminal 1 and the terminal 2 is completed and both are in the connectable state, the connection is established.

In the above embodiment, the schedule information is used as the subscriber information indicating the temporal enjoyment of the exchange service. However, in the mobile communication network, the presence / absence of the seat is used by using the position information indicating the terminal location. Therefore, the location information can be regarded as the subscriber information indicating the temporal enjoyment of the exchange service.

For simplification of the subscriber information, only two states, attended and absent, are described, but the subscriber information added with detailed service information such as using voice mail when not present is the same. It can be processed using the configuration.

[0020]

As described above, according to the present invention, by storing the subscriber information for each time zone of the exchange service in the main memory, the subscriber information need only be referred to in the main memory, so that high-speed exchange processing is possible. It is possible. Further, since only the subscriber information necessary for the time of the exchange service is in the main memory, the capacity of the main memory can be small.
