Description

Functional unity apparatus and method of compact-BSC}

The present invention relates to a compact base station controller (BSC) of a communication system, and in particular, integrates the statistical functions of a base station manager (BSM) and a BSC to process data, thereby processing the performance and resources of each processor according to statistical data transmission. A device and method for integrating the functions of a Compaq BSC system to improve the efficiency of (memory).

In the current PCS system, statistical data processing is collected by BTC and processed by BTC / BSC, but the compact BSC system integrates and processes the functions of BSM and BSC.

The Compaq BSC is a small-capacity system that uses the PC standard buses, Compaq PCI and H.110 Radware and Software, located between NSC and BTS to interface with the MSC through the IS0634 protocol and the BTS with the IPC protocol.

Compaq BSC's main processor handles call resource management, operator matching, fault / alarm processing and management, status management, system diagnostic management, BSC call processing, system configuration management, and system loading in the base station and Compaq BSC.

In the conventional statistical data collection, when a SMSM (Statistics Measure and Manage eXecution), which is a BSM statistics block, makes a data request to a CMSC (Ccp Measure Manage eXecution) that is a BSC statistics block, data is collected from a lower interworking processor and transmitted to the SMMX.

At this time, since the data transmission from the BSC to the BSM is performed through the packet transmission method, the data transmission speed is lowered and the performance of the processor is reduced during the data transmission.

Here, the maximum number of packets transmitted is about 50,000, and if the transmission packet is lost due to the abnormality of the system between the BSC and the BSM when transmitting the statistical data from the BSC to the BSM, the statistical data stability and reliability will be weakened.

In addition, the size of memory allocated for storing temporary statistical data in the BSC is the largest among other APs of Compact-BSC Call Processing (CCP), which is an issue that needs to be improved in view of the limited memory size in the CCP. .

Conventionally, although the delay time is an optimal time within the limit of no packet loss, the delay time takes about half of the transmission time, which is different from the actual packet transmission time.

As a result, it can be seen that the statistical data processing time between the BSC and BSM is a problem in the packet transmission method between processors, which becomes a obstacle in processing the statistical data in real time.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to integrate statistical blocks of BSC and BSM to improve data transmission speed and processor performance during data collection and to directly transmit statistical data from lower-linked processors. The present invention provides an apparatus and method for integrating a function of a compact BCS system that can reduce the waste of memory for storing temporary statistical data in an existing BSC by collecting and storing the data.

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

1 is a block diagram of the CSMMX 10 of the present invention, every 10 minutes, the call processing block calls the corresponding library every time an event occurs, reads and stores the data generated in the library buffer, and requests data from the lower interlocking blocks. After collecting and storing the data in the statistical data file, the data requesting unit (1) and the data collecting / storing unit (2) for processing the stored data in the data output unit or the database processing unit, and CUIMX (Compact-) Syntax and Semantic check in BSC User Interface Manager eXecution, and then forks the CSMMX to transmit the parameter values of the input command to the CSMMX through the pipe, and to analyze and process the transmitted commands. Command processing unit 3, data output unit 4 for formatting the statistical data and outputting the screen to the message output window of CUIMX, and a statistical database. And sikimyeo sex, type of statistical data after the reset signal to the message database and updates, is configured as a database processing unit 5 for retrieving and outputting the statistical data to the database via the operator command.

In the figure, 6 is a statistical database, 7 is an alarm, a fault, 8 is a signal input and output part to the input and output signal messages.

Referring to the operation of the present invention configured as described above is as follows.

The functions of the CSMMX 10 of the present invention can be broadly divided into two types. First, the statistics function of the existing BSC statistics block, CMMX, and second, the statistics function of the BSM statistics block SMMX.

That is, it is divided into data measurement and collection function from CMMX subordinate processor, SMMX operator reservation function and data output function.

CSMMX creates a thread that executes the functions of CMMX and a thread that calls the library every 10 seconds to measure the traffic occupancy time. It is a daemon that schedules statistics and prints data by the operator, a statistics function inside CMP. To perform a task independently of the process.

The collection of statistical data takes place after a data request is made to the lower interlocking blocks every 10 minutes.

In other words, every 10 minutes, the statistical data file is initialized and the lower interlocking blocks are requested.

Next, the CCPX interworking library, a CMP call processing block, is called to store the generated statistical data in the statistical data file.

Collect NO.7 statistics data from CSB block, read from alarm, fault, and statistics file and save in statistics data file.

After collecting data from the lower interlocking blocks, CSMMX proceeds to the next step, output.

The reservation and output of the statistical data is performed as follows.

That is, the output order of the collected statistical data is in the order of the statistical data report and the periodic statistical report reserved by the MMC.

The operator can reserve the statistical data, measurement cycle, measurement frequency, etc. by MMC command, and reserve the statistical data output of the user.Measurement / acquisition / stored statistical data can be reserved at this time. Output by search.

Periodic statistics output hourly / daily / monthly statistical data output can also be run or stopped by the operator command.

Figure 2 shows the CSMMX statistical data processing sequence, step S1 for generating a statistical data file and a thread for interworking with a lower processor, step S2 for processing a signal by waiting in a queue, step S3 for checking a message type, If mtype is 2, it initializes the statistics database with the process operation for CMP internal processing, sends the 10 minute signal to the sub-interworking processor for the statistics data request to the statistics dedicated queue with mtype 3, and alerts, faults, S4 step of collecting the statistical data, calling the library and storing it in the statistical database; if mtype is 3 in the S3 step, S5 step of determining whether the signal is a 10-minute signal in the thread operation for the sub-interworking processor processing, 10 in the S5 step If the signal is minutes, S6 waits for a queue after requesting data from the subordinate interworking processor. After collecting the data from the lower interworking processors and storing the data in the statistical database file step S7 to go to the queue waiting routine, in step S4 determines whether or not the statistics reservation mode in step S9 outputs the statistical data after the queue standby routine, If it is not in the statistics reservation mode in step S8 is made to step S10 to go to the queue waiting routine.

In the above, mtype refers to processing by dividing by message type when reading a message from the message queue.

In this case, the CSMMX_main.c (11) is a unit including a routine for the CSMMX branched from the CSIMX or the CUIMX and other common use routines.

When branching from CSIMX, branch to CSMMX_daemon.c (13) to enter daemon routine. When branching from CUIMX, branch to CSMM_proc_mmc.c to finish MMC instruction processing, update the statistics database, and output it.

The CSMMX_proc_mmc.c (14) ends after completing CSMMX instruction processing and MMC database processing accordingly.

The CSMMX_user.c (17) includes a user request statistics routine reserved by an MMC instruction.

The CSMMX_seven.c.c (15) includes a routine for searching the NO.7 statistics database, updating the statistics database, and outputting a NO.7 related statistical message.

CSMMX_db_gen.c (12) includes routines for creating and initializing statistical data files.

CSMMX_daemon.c (13) is a unit that constitutes the daemon of CSMMX, and processes the statistical data for each item by creating a thread in a unit that includes statistical data request / collection / statistical database processing and periodic statistical report processing routines from lower interlocking blocks. Do it.

CSMMX_rpt_handle.c (16) analyzes signals of statistical data collected from lower interlocking blocks and stores data for each statistical item.

FIG. 4 is a diagram of control between processors, which is branched from CSIMX 21 and CUIMX 22 to read / write statistics database 24 from CSMMX 23, and includes NO.7 block, alarm, fault data, It shows the interworking relationship between CMP statistics library, BSCX, HICA, BMMX, BOCX.

As described above, the present invention can perform the main process functions of the CMP board and the existing BSC and BSM according to the integration of the functions of the BSC and BSM, thereby reducing the cost of the board.

In addition, due to the data collection method stored in the statistical database by calling library functions in packet transmission method when collecting data interlocked with CMP call processing that handles most of the statistical data, it is possible to reduce the time required for collecting statistical data from the interworking processors. This improves processor performance and memory efficiency.
