DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile switching center, a maintenance operation center connected to the mobile switching center, and a plurality of base station controllers connected to the mobile switching center.
NO. The present invention relates to a point code setting method for a base station controller, which sets a point code for signal control in each of the base station controllers in a mobile communication system connected by a common channel signaling system.

[0002]

2. Description of the Related Art A mobile communication switching center, a maintenance operation center connected to the mobile communication switching center for maintenance and the like of a mobile communication system, and a plurality of base station connecting devices similarly connected to the mobile communication switching center are connected to each other. In addition to the normal communication line, NO. 7 common signal lines, through which line non-corresponding signals such as mobile station movement information, subscriber information, and billing information are transferred.

Conventionally, when a point code for signal control, which is an identification code, is set in a base station controller, a point code of the base station controller is set in the base station controller at the time of system development. The developer checks and confirms the point codes of the mobile communication switching center and the maintenance operation center corresponding to the base station control device, and sets them as individual data. FIG. 3 is a diagram showing a situation in which each base station controller individually sets each point code in this type of mobile communication system.

That is, in FIG. 3, for example, when a base station controller BS2 is introduced into the system 1, this device B
S2 is the mobile switching center MS1 and the maintenance operation center OM1
, The point code “03” of the base station controller BS2 is used as individual data of the base station controller BS2.
-002 ", the point code" 01-001 "of the mobile switching center MS1, and the point code" 02-001 "of the maintenance and operation center OM1. Also, when introducing the base station controller BS50 into the system 1, the point code "03-0" of the base station controller BS50 is used.
Except that "50" is different from the base station controller BS2, the point codes of the mobile switching center and the maintenance and operation center are the same as those of the base station BS2.

In this manner, each time a base station controller is newly installed in the system, in addition to its own point code, each point of the mobile communication switching center and the maintenance and operation center in the mobile communication system. The code is set.

[0006]

As described above, the point codes set in the base station controllers installed and arranged in the same system are the same as those in the mobile communication switching system except that the point codes for the base station controllers are different. As shown in FIG. 3, the same point codes for the station and the operation and maintenance center are all set to the same code from the base station controller BS1 to the base station controller BS50. Despite this situation,
The base station controller developer must check and set the mobile communication switching center point code and the maintenance operation center point code for each of the installed base station controllers. The work is complicated, so that the time required for the setting is long, and there is a fear that an erroneous setting may be caused.
Therefore, an object of the present invention is to simplify the work of setting a point code for a base station control device and prevent erroneous setting of a point code.

[0007]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention has been developed by using NO. (7) Within the common signaling network, a mobile switching center to which a first point code is assigned, a maintenance operation center connected to the mobile switching center and assigned a second point code, and a mobile switching center connected to the mobile switching center. A plurality of base station controllers to which different third point codes are assigned are provided,

[0008]

In each base station controller, a storage means for storing a third point code is provided, and each third point code and the first and second points corresponding to each of the third point codes are provided. The point code is stored in the database as common data. As a result, when a point code is set by the base station controller, the corresponding first and second point codes in the common data are automatically set, so that the point code setting operation is omitted, and therefore, setting errors are eliminated. This makes it possible to prevent erroneous setting of the point code due to the like. In addition, the base station control device reads the third point code of the own device during the initialization process before the normal process is started, and if the third point code matches the third point code in the common data, the third point code is read. The first and second point codes in the common data corresponding to the point code are set in the own device. As a result, when the point code is set, it can be set without affecting normal processing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a mobile communication system to which the present invention is applied. In FIG. 1, reference numerals 1 and 2 denote mobile communication systems. The mobile communication system 1 includes 50 base station controllers BS1 connected to a mobile switching center MS1, a maintenance operation center OM1, and a mobile switching center MS1.
To BS50. Each of these parts is provided with a CCITT-defined NO. No. 7 common signal line (No. 7 common signal network). Via this signal line, in addition to line correspondence information such as call control information, line non-correspondence such as mobile station movement information, subscriber information, and billing information. Signals are also transferred.

The mobile communication system 1 and the above-mentioned NO.
The mobile communication system 2 connected by the common signal line 7 includes a mobile communication switching center MS2, a maintenance operation center OM2, and 50 base station controllers B connected to the mobile communication switching center MS2.
It is composed of T1 to BT50. Each of these parts is also the same as the above-mentioned NO. 7 are provided in the common signaling network. In a system configured in this way, when a point code for signal control, which is an identification code, is set for each base station controller, conventionally, the same is applied every time each base station controller is provided in the system. Since each point code of the mobile communication switching center and the maintenance operation center in the system is set, there is a disadvantage that the setting is complicated.

Therefore, in this embodiment, the above-mentioned NO. The database 3 is connected to the 7 common signal lines, and each base station controller is configured to read out and set a point code for the own device from the database 3. That is, in the column of the base station control device of the database 3 in FIG. 1, each of the base station control devices BS1,..., BS50, BT
, "03-001", ..., "0"
The point codes of the base station controllers of “3-050”, “03-051”,... Are stored as common data. .., “0” of the mobile communication switching center corresponding to each point code of each base station controller.
1-001 "," 01-002 ",... Are stored, and the" 02-00 "of the maintenance and operation center corresponds to the point code of each base station controller.
1 ", ...," 02-001 "," 02-002 ",
.. Are stored as common data.

An RA (not shown) of each base station controller
In a memory such as M, a point code of the own apparatus is set and stored in advance. Each base station controller searches the database 3 for a matching point code based on its own point code at the time of the initialization processing, and the mobile communication switching center corresponding to the base station controller having the matching point code and the maintenance operation are performed. Each point code of the center is read from the database 3 and set and stored in its own memory. As described above, since the point codes of the mobile communication switching center and the maintenance and operation center in the system in which the own apparatus is provided can be automatically set at the time of the initialization processing, the point code can be set in the base station controller in a short time and reliably. Can be set to

FIG. 2 is a flowchart showing the operation of the main part of the present invention, and shows the operation of setting a point code of the base station controller when the base station controller is installed in the system. That is, in the initialization processing when the base station controller is provided in the system and turned on, first, in step ST1, the base station controller reads its own point code set and stored in the memory. Next, the base station controller reads out the point code of the base station controller BS1 from among the point codes of the respective base station controllers stored as common data in the database 3, and in step ST2, reads the point code of its own device. Compare.

At step ST3, it is determined whether the point codes match, and if they do not match, the process proceeds to step ST4. In step ST4, the point code of the next base station control device in the common data is read out, and the process returns to step ST2, where it is compared with the point code of the own device in step ST2. Thus, the point code of each base station control device in the common data is sequentially read out and compared with the point code of the own device.

Then, as a result of comparison of each point code,
If the two point codes match and the determination in step ST3 is "YES", the base station control device proceeds to step ST3.
In step 5, the point code of the mobile communication switching center and the point code of the maintenance and operation center corresponding to the base station controller having the same point code on the common data are read out, set and stored in its own memory, and the initialization process is completed. I do.

As described above, at the time of initialization of the base station controller, the base station controller accesses the common data in the database 3 based on the point code preset and stored in the base station controller, and stores the common data in the common data. Each point code of the set mobile communication switching center and maintenance operation center is read out and set in its own device. As a result, as compared with the point code setting of the conventional base station controller, the setting time is greatly reduced, erroneous operations such as setting mistakes are prevented, and the point code can be set accurately.

[0017]

As described above, according to the present invention, each base station controller is provided with storage means for storing a third point code which is a point code of each base station controller, and each third base station controller is provided with a third point code. And a first point code which is a point code of the mobile communication switching center corresponding to each of these third point codes, and a second point code which is a point code of the maintenance and operation center.
Since it is stored in the database as common data, when setting the point code in the base station controller,
Since the corresponding first and second point codes in the common data can be automatically set, the operation of setting the point code is omitted, and thus the erroneous setting of the point code due to a setting error or the like can be prevented. In addition, the base station control apparatus performs its own third processing during the initialization processing before the normal processing is started.
Is read, and if this matches the third point code in the common data, the first and second point codes in the common data corresponding to the third point code are set in the own device. Therefore, when setting the point code, the point code can be surely set without affecting the normal processing.
