Abstract

PURPOSE: A method for transmitting blacklist data is provided to change data for an efficient operation of a CT-2 BS(Base Station), in transmitting the blacklist data using a modem between the CT-2 BS and a BSMS(Base Station Management System). CONSTITUTION: If an operator intends to update blacklist data as a whole(100), a BSMS sets a communicating modem for communication with a BS(101). If the BSMS succeeds in the communication through the modem, the BSMS transmits "BL_ALL_UPDATE_REQ" to the BS(103). The BS initializes a stored blacklist(105), and transmits "BL_ALL_UPDATE_RES" to the BSMS(106). The BSMS transmits the blacklist data to the BS(117). If a predetermined time for downloading the blacklist data comes(107), the BSMS calls a telephone to registered base stations(109), and sets the modem(110). If the BSMS succeeds in connection through the modem, the BSMS transmits "BL_TIME_REQ" to the BS(112). The BS transmits "BL_TIME_RES" to the BSMS(114). The BSMS compares a time of updating the blacklist information stored in the BS to a time stored in the BSMS(115). If the times are different, the BSMS transmits the updated blacklist thereafter to the BS, on the basis of the transmission time in the step 114(117).

How to send bad subscriber list and manage list

The present invention relates to a method for managing bad subscribers in a base station, and in particular, in transmitting bad subscriber data using a modem between a CT-2 base station and a base station management apparatus, by varying the data for effective operation of the base station. The present invention relates to a transmission technology, a transmission method, and a method of transmitting and managing a list of bad subscribers to ensure reliability of transmission data.

In general, the base station determines whether the base station accepts the management of bad subscribers is largely determined by the connection method between the base station and the base station management device. As a conventional product, the following CT-2 products can be seen. .

1) Ericsson (Orbitel) product in the UK using Dial-Up modem

2) Dassult products of France using dedicated line

-The structure is different because the method for inquiring about the defective subscriber does not process at the base station, but at the base station controller (hereinafter referred to as BSC).

3) CT-2 Plus Family in Canada

4) NT's CT-2 product line and so on.

If the dedicated base line is used in the upper base station management device, the base station price can be lowered, but the operation cost is high without the advanced application of the line technology because the circuit must always be used in terms of operation.

Therefore, the present invention can be applied in view of storing bad subscriber information in a base station using a dial-up modem.

In order to accommodate the information on the bad subscriber to the base station, a separate storage space should be secured at the base station.

An effective method for storing bad subscribers and a processor used in a base station need to retrieve a large number of bad subscriber information in the call processing step. Done.

Accordingly, the present invention has been devised to solve the above-mentioned problems, and in the transmission of bad subscriber data using a modem between the CT-2 base station and the base station management apparatus, the data for effective operation of the base station The purpose of the present invention is to provide a method of transmitting and managing a list of bad subscribers, which can guarantee the reliability of data transmission technology, transmission method, and transmission data by varying.

Exemplary embodiments of the present invention have the advantage that the circuit cost can be reduced when the connection between the base station and the base station management apparatus using a dial-up modem is used, except in the case of using a dedicated line in the base station upper management apparatus.

Since a public switched telephone network (abbreviated as PSTN) is used instead of a dedicated line, a list of bad subscribers necessary for a base station is obtained from a base station management device at a time when the call is not busy. Take a way to download it.

Therefore, in the CT-2 base station and base station management system having the same structure as the present invention, a separate design for managing a bad subscriber is required.

In the base station and the base station management apparatus, a method of minimizing the bad subscriber information for transmitting the bad subscriber list, an inquiry algorithm for the purpose of querying the bad subscribers from the base station, a method for transmitting the bad subscriber information from the base station management apparatus to the base station, and the base station The processing method in a management apparatus is proposed.

The present invention is composed of a base station (hereinafter referred to as BS or less) and a higher level device comprising a base station management device (hereinafter referred to as BSMS or BSMS) and a subscriber management device (hereinafter referred to as BSMS or less). It includes subscriber management device (SMS) interworking for interworking.

The information on the blacklist among other providers is provided to each operator through interworking between subscriber management devices (SMS).

Referring to Figures 1 and 2 will be described in detail the configuration of the present invention.

The base station 2 and the base station management apparatus 4 are connected to each other by using modems 21 and 41. However, one modem may be used for the base station 2 or two modems may be installed in consideration of stability. .

In the base station management apparatus 4, the configuration may vary depending on the number of base stations 2, but the base station management apparatus 4 at a ratio of 50 to 100: 1 compared to the base station in view of the concept of data transmission when necessary rather than a dedicated line concept. Install the modem 41.

The base station 2 has an index for searching for a bad subscriber in authentication for each service provider to store the bad subscriber list.

The base station management apparatus 4 operates as a subject for transmitting the bad subscriber list to the base station 2, and has a separate data transmission structure for the consistency of the list with the base station 2.

The base station management device 4 stores the bad subscriber received from the subscriber management device 5 in the database.

In the base station management apparatus 4, one of the two methods of downloading all the bad subscribers up to now or only the bad subscribers generated at the time since the most recent download is performed in order to transmit the bad subscriber list to the base station 2; You can select and use.

If a bad subscriber list is not transmitted to a specific base station 2 due to a failure of modem connection at a designated time, a separate list management for retransmitting the bad subscriber list is performed.

The subscriber management apparatus 5 for managing bad subscriber data is configured, information on all subscribers is stored, and a bad list is created and managed.

The newly registered bad subscriber in the subscriber management device 5 is transmitted to the base station management device 4 in real time.

In the subscriber management apparatus 5 transmitting the newly registered bad subscriber list to the base station management apparatus 4 in real time, the communication between the subscriber management apparatus 5 and the base station management apparatus 4 uses the X.25 protocol. do.

Here, the operation principle of the method of transmitting and managing the list of bad subscribers according to the present invention will be described in detail.

The base station 2 and the base station management apparatus 4 are connected using the public switched telephone network 3 interface, as shown in FIG.

The base station 2 may support five public switched telephone network 3 circuits for four radio frequency (RF) channels, as shown in FIG. 2, to configure line duplication.

The modem 21 in the base station 2 may use one modem or up to two modems.

The base station management apparatus 4 uses 32 modems 41 and 64 modems for redundancy.

The telephone number used for the management device is configured to use a representative telephone, a divided representative telephone, or have a respective telephone number.

The connection between the base station management device 4 and the subscriber management device 5 is interfaced using X.25.

The subscriber management device 5 registers a subscriber to the CT-2 subscriber and pre-registers the subscriber.

In order to register the terminal usage information to the subscriber, wireless notarization registration (hereinafter referred to as OTAR) is performed, and in this process, the terminal, the base station, the base station management apparatus, and the subscriber management apparatus are connected in real time to use the terminal. Is stored in the terminal, and if the terminal is successfully used by checking whether the terminal is in a usable state, the subscriber is registered in the subscriber management apparatus 5.

When the subscriber is in the registered state, as shown in FIG. 4, the registration state is managed using a customer ID (Subscriber IDentification code: SID hereinafter) and a terminal identification code (PID).

The customer number (also called the billing number) is the only value used by the operator.

Each terminal has a unique terminal identification code (PID), and the general subscriber is not registered with more than one operator because they are in the national service area.

However, when registering to two or more operators, managing bad subscribers with only a terminal identification code may be a problem because even registered subscribers to third parties are affected because of bad subscribers registered in one operator.

Therefore, when there are terminals registered to two or more providers, it is necessary to distinguish between the providers.

The base station 2 can be configured to store bad subscribers for 15 operators, and designate a bad subscriber list (Biacklist Sharing Index) used in the authentication process for each service provider. You can choose.

The information on the bad subscriber causes the base station management apparatus 4 to determine an update as time information finally updated.

In order to minimize the storage area of the bad subscriber information in the base station 2, as shown in FIG. 3, a hash table is constructed using a Divide Hash Function of “10: 1”. Search using a terminal identification code (PID).

The processing of the failure details corresponding to each terminal identification code (PID) is stored using a field called action.

Processing for transmitting the bad subscriber to the base station 2 is as shown in FIG.

First, the base station 2 is operated to be out of the initial installation mode and to be in standby (IDLE) or call processing mode, and the operator selects the whole renewal of the bad subscribers for the base station 2 registered in the base station management apparatus 4. If 100, a communication modem is set for communication with the modem 21 with the base station 2. [101]

If the modem communication fails, it reports to the operator (102).

On the other hand, if modem communication is successful, the base station management apparatus transmits "BL_ALL_UPDATE_REQ" to the base station (103), the base station 2 initializes the stored bad subscriber list (105), and then transmits "BL_ALL_UPDATE_RES" to the base station management apparatus. And transmits to (4) (106).

The base station management apparatus 4 which received this message transmits a bad subscriber to the base station 2 (117).

On the other hand, when the bad subscriber download time specified by the management apparatus is reached without updating all the bad subscribers (107), the base station management apparatus 4 calls the registered base stations 2 (109).

On the other hand, when the operator downloads the failure list or the specific base station 2 (108), the modem 41 of the base station management apparatus 4 is set (110).

At this time, when the base station management apparatus 4 fails to set up the modem 41, the base station 2 registers the ID "111" in the failure list (111). If the connection is successful, the base station 2 receives "BL_TIME_REQ". And transmit (112).

The base station 2 transmits "BL_TIME_RES" to the base station management apparatus 4 (114).

The base station management apparatus 4 compares 115 the bad subscriber information update time stored in the base station 2 with the time stored in the base station management apparatus 4, and if the time does not match, the base station 2 On the basis of the transmitted time, the bad subscriber list updated thereafter is transmitted to the base station 2 (117).

On the other hand, if the time between the base station management device 4 and the base station 2 is the same, the processing for the current base station 2 is terminated for processing for the other base station 2 (116).

On the other hand, if all of the bad subscriber information is transmitted from the base station management apparatus 4 to the base station 2 as described above (118), "BL_DNLD_END" is transmitted to the base station 2 (119).

At this time, the final update time to be transmitted to the base station 2 is transmitted together (120).

The bad subscriber information to be stored in the base station 2 is updated according to the operation sequence as described above.

As described in detail above, the present invention,

Since the size of the bad subscriber data is relatively smaller than using the subscriber number (SID) (6 bytes), the time required for the transmission of a large amount of data (for transmitting bad subscriber information for 200,000 subscribers) is shortened. do.

In addition, by implementing the function of the full update during transmission of the bad subscriber, it is possible to match the data in various base stations and arbitrary designation for a specific base station.

By using a hash function at the base station, the processing time required to store and query a bad subscriber can be shortened.

Since the modem is used to communicate with the base station and the base station management apparatus, when the terminal terminates in any situation, the base station management apparatus may provide information to the operator by providing a retransmission and failure list.

The base station can be specified to share the list of bad subscribers for the operator group, it is possible to minimize the storage area of the bad subscriber stored in the base station.
