Description

Apparatus and method for collecting statistical data of mobile communication system {APPARATUS AND METHOD FOR COLLECTING STATISTIC DATA IN MOBILE COMMUNICATION SYSTEM}

The present invention relates to an apparatus and method for collecting statistical data in a mobile communication system, and more particularly, to a method for storing statistical data at a base station.

The statistical part that generates, collects, and analyzes performance data in a mobile communication system collects and processes statistical items in a base block system (BTS) and periodically reports them to a base station management (BSM). At this time, if the transmission is not done properly due to a link problem or system down, the PCS system ignores the data of the cycle. In this case, it is impossible to derive the accurate statistics in producing statistics with the collected data.

Accordingly, an object of the present invention is to provide an apparatus and method for storing statistical data of a period not transmitted in a mobile communication system and transmitting data not transmitted in a next period.

A base transceiver system (BTS) collects statistical data and periodically transmits the statistical data to a base station controller (BSC), and the control station collects statistical data from a plurality of base stations. The method for collecting the statistical data in a mobile communication system that transmits to a base station management (BSM) includes a process of accumulating and storing statistical data of a failed transmission of the statistical block of the base station, and a statistical block of the base station. Transmitting the cumulatively stored statistical data to the control station together with the cumulatively stored number of times, and a statistical block of the control station is divided by the cumulative number of stored statistics data from the base station and allocated for each transmission period. Storing in each storage area, and the statistical block of the control station is obtained from a plurality of base stations. One to collect and process statistical data base manager: characterized by consisting of a process of transmitting a (BSM Base Station Management).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding the reference numerals to the components of each drawing, the same components have the same reference numerals as much as possible even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a statistical data transmission in a mobile communication system according to the present invention.

Referring to FIG. 1, a configuration includes statistical and measurement manager (SMM) 111, main measurement and statistics handling (MMH) 112, main measurement and statistics library (MML) 113, and BTS measurement and statistics handling (BMH) 114. The SMM111 is driven by a base station management (BSM), the MMH112 and MML113 are driven by a base station controller, and the BMH114 is driven by a base transceiver station (BTS). The BMH114 collects statistical data generated in the BTS and transmits it to the MMH112 in the BSC. The MMH112 collects and processes the data transmitted from the BTS and the data collected by the BSC itself and transmits the data to the SMM111 of the BSM. Here, the BSC and the BTS statistics block collects, stores, and transmits data. Even though the storage structure is changed, data is continuously maintained even when transmission is not smooth.

The SMM111 performs a function of statistical processing, storage and output of various data measured by a subsystem. When a measurement request of the subsystem is required, a plan such as the type and number of measurements can be defined and registered, and can be suspended as necessary. In addition, by using the control command, you can control whether to print the screen, whether to print or not, and create a statistical data report by time and date.

The MMH112 is a program that tracks and records all meaningful events occurring in the control station, and provides basic data for system status, maintenance, performance evaluation, mid-to-long term design, and the like. For example, it collects and reports events occurring in the control station, and measures and reports the amount of calls occurring in the control station.

The MML113 is a library used by the BMP subsystem and is a block for storing data necessary for statistics when a call occurs, that is, common data between the call processing block and the MMH112.

Measurements and statistics measure data such as call volume, call distribution, call quality, call capacity calculation data, and fault characteristics that occur during system operation. Collect and analyze for indirect use. General statistics are as follows. Traffic statistics, handoff statistics, channel element statistics, vocoder statistics, base station trunk line link statistics, radio channel quality statistics, processor statistics, failure statistics, alarm statistics, base station performance statistics, Paging statistics, base station location registration statistics, date (Day / Week / Month) statistics, and the like.

2 is a diagram illustrating a case where communication between a BSC and a BTS is performed at one time.

Referring to FIG. 2, the MMH112 requests data from the BMH114 at the set time (msg_ReqStat_MmhBmh). Then, the BMH114 sends the configuration information of the BTS to msg_RspStat_BmhMmh first, and then transmits data for each statistical item for the actual operation item to msg_RspStat_BmhMmh for each item and transmits it to the MMH. When the item-specific data transmission is completed, the MMH informs the BMH114 whether the data transmission has been well performed or an error has occurred through msg_InfStat_MmhBmh. This completes one cycle of data transfer.

3 is a diagram illustrating a case where communication between the BSC and the BTS is not performed at one time.

Referring to FIG. 3, the MMH112 requests data from the BMH114 at the set time (msg_ReqStat_MmhBmh). Then, the BMH114 sends the configuration information of the BTS to msg_RspStat_BmhMmh first, and then transmits the data of each statistical item for the actual operation item to msg_RspStat_BmhMmh for each item and transmits it to the MMH112. When the item-specific data transmission is completed, the MMH112 informs the BMH114 whether the data transmission has been well performed or an error has occurred through msg_InfStat_MmhBmh. If an error occurs, the error occurrence item is loaded in msg_RepStat_BmhMmh and transmitted to MMH112. When the data transmission for each item is completed, the MMH112 informs the completion of data transmission through msg_InfStat_MnhBmh.

In the same process as described above, transmission is performed between the MMH112 and the BMH114. If a problem occurs between the BSC and the BTS, data transmission cannot be performed. For example, if a link is broken between the BSC and the BTS, or a problem occurs in one of the BSC and the BTS system, the data cannot be transmitted. In the existing mobile communication system, when such a situation occurs, only one cycle of data can be stored in each system, so that the data is lost, and the BSM also obtains statistical data except for this time.

For example, if we look at the paging statistic, we first assume that there are three items in the paging statistic. Here, the data is periodically transmitted to the BSC for each BTS, and the existing BTS paging data structure is shown in Table 1 below.

BTS No item 0 item 1 item 2

Therefore, the existing BSC paging data structure is stored as shown in Table 2 below and transmitted to the BSM.

BTS No item 0 item 1 item 2 BTS No · · · BTS No item 0 item 1 item 2

If data cannot be transmitted due to anxiety or external factors, data is transmitted without being stored as in the second row. In this case, data loss occurs.

That is, in the present invention, in order to prevent such a case, a new item is added to the data structure. As shown in Table 3 below, 'DUAL_CNT' is placed after 'BTS No' to accumulate data.

BTS No DUAL_CNT item 0 item 1 item 2

For example, the BSC paging data structure according to the present invention is stored as shown in Table 4 below.

BTS No One item 0 item 1 item 2 BTS No 3 item 0 item 1 item 2 BTS No One item 0 item 1 item 2

Referring to Table 4, BTS 0 and BTS 2 have only one cycle of data (most normal case), and BTS 1 accumulates data of the past three cycles. In this case, the third data is transmitted without being transmitted in the past two periods. The BSM receives the transmission data, knows that BTS 1 is accumulated data three times, divides the items into three to generate average data, and stores the generated average data in a data item (storage area) set for each period. Then, when you get the averaged statistical data, you can get more accurate statistics.

In addition, when the DUAL_CNT is filled with a value less than 1, it may also be indicated that an error occurred during data collection. In this case, the BSM can increase reliability by obtaining data except for a period in which an error occurs when obtaining averaged statistical data.

As described above, the present invention can obtain more accurate and reliable statistical data even in abnormal situations of the system that may occur when generating and collecting statistical data in the mobile communication system, thereby contributing to stabilization of the system and performance analysis of the system. This can be important in terms of the operator's operational aspects.
