Abstract

PURPOSE: A method for searching destination codes at a minimum in an MSC(Mobile Station Controller) is provided to reduce the load of call processing and to improve the performance of a system by minimizing the comparison frequency between an inputted destination code and registered destination codes. CONSTITUTION: An MSC calls a statistical library(ST11) and judges whether the statistical library is the first statistical event(ST12). If the statistical library is the first statistical event, the MSC compares an inputted destination code with a registered destination code and obtains a destination code index(ST13). The MSC stores the obtained destination code index in a call register(ST14) and records the first statistical event(ST15). However, in case that it is judged that the statistical library is not the first statistical event, the MSC checks whether a destination code index equivalent to an relevant call register value is positive(ST16). If the destination code index is positive, the MSC records the destination code statistical event in an area corresponding to the destination code index(ST17). Then the MSC records the outgoing call statistical event(ST18).

Description

Method for detecting minimum incoming code in mobile communication exchnage}

The present invention relates to a mobile communication switch, and more particularly, to a method for reducing call processing load and improving system performance by minimizing the number of comparisons between an incoming terminating code and a registered terminating code for collecting terminating code statistical data. .

In general, a mobile communication system is a system that enables communication while moving with a mobile terminal (mobile station).

1 is a block diagram for collecting incoming code statistical data of a general mobile communication exchange.

As shown therein, a TCR (Trunk Call Control for R2-MFC) 11 for processing R2 relay calls and TC7 (Trunk Call Control for SS No) for handling ISUP (ISDN User Part, ISDN user part) relay calls .7) (12), a function of collecting and transmitting statistical system library (STSL) 13, which is a statistical library block of relay calls processed by TC7 (13), and statistical data collected by the STSL (13). An access switching processor (ASP) 10 which processes outgoing calls, including measurement and statistics gathering data on route (MSGR) 14; Processor for performing the operation preservation function of the entire mobile station controller (MSC), including Measurements and Statistics Data Processing (MSDP) 21, which processes the collected incoming code statistical data transmitted from the MSGR 14 OMP (Operation and Maintenance Processor) 20.

2 is a flowchart illustrating a conventional method of collecting called code statistical data.

As shown therein, a step of searching for all the incoming call codes that can be registered to search whether the current incoming code is registered (ST1) (ST2); If the current incoming code is registered, comparing with the digits inputted from the same first digit, if the digits are different during the comparison, stopping the comparison and recording the number of comparisons (ST3); The comparison number of the previous loops and the current comparison number are compared again, and if the comparison number is large, the corresponding index is stored (ST4).

When described in detail with reference to the accompanying drawings of the conventional incoming code statistical data collection method configured as follows.

First, the TCR 11 and the TC7 12, which are software blocks for handling outgoing call occurrences, record the details in the STSL 13 through the library whenever a defined incoming code event occurs. The incoming code statistical data recorded in the STSL 13 periodically or at the request of the operator are read by the MSGR 14 and transmitted to the MSDP 21, and the MSDP 21 is required for the received incoming code statistical data. The result is processed and output.

In this case, a call that arrives at another exchange in a mobile switching center (MSC) is called an outgoing call, and the incoming code statistics is a function of measuring traffic by outgoing station number registered by the operator for such outgoing call. .

Therefore, in order to measure incoming code statistical data, a function for checking whether the station number processed until the outbound call is terminated is an incoming code registered by the operator.

In the incoming code statistics, statistical data should be measured for each call state. Therefore, the incoming code statistics library should be called whenever an event defined in statistics occurs until one outgoing call is generated and terminated. Currently five statistical events are defined. Defined statistical events are outgoing occupancy attempts, seized, alert, answer, answer, release, release by normal termination and incomplete. In the called code statistics library, the incoming code, which is the input parameter and the currently registered call code, is compared with the currently registered call code to record another input parameter, the statistical event, in the designated library area. If it returns immediately. In addition, in the called code statistics, the incoming call code is compared with the registered incoming call code from the first digit, and the called code statistics are performed only for the registered code with the largest number of comparisons.

That is, the comparison start route is first performed (ST1). Here, the comparison is performed for all the incoming call codes that can be registered. Since the registered called code is stored in the database, the comparison is performed for the maximum possible database tuple. The tuple stores the registered called code and its length.

It checks if the incoming code is registered in the current tuple. The investigated content is the length of the registered called code. If the length of the incoming code is "0", it is regarded as not registered and the comparison start loop ST1 is restarted to execute the next route (ST2).

If the called code is registered here, it is compared with the digit entered from the first digit. If the digits differ during the comparison, the comparison is stopped and the number of comparisons is recorded (ST3).

So we compare the number of comparisons of the previous loops with the number of comparisons. If the previous comparison count is large, the comparison start loop ST1 is restarted to perform the next loop (ST4). If the comparison count is large, the corresponding index is stored (ST5).

Conventionally, the registered incoming code is possible from the minimum of 2 digits to the maximum of 16 digits, and the number of the registered incoming codes can be up to 10. In the worst case, all registered call codes are 16 digits, the incoming call code is also 16 digits, the first 15 digits are all the same, only one digit is different, and the incoming call code is the same as the 10th registered call code. The number of comparisons is 16 × 10, or 160 times. In addition, since five statistical events are defined in one outgoing call, the worst case is 160 × 5, or 800 comparisons, until the outgoing call ends, resulting in an increase in call processing load. .

In the statistics function of New Century Communication, the number of incoming codes that can be input is 20, and the number of incoming codes that can be registered is 64. Therefore, when using the conventional method, the number of incoming codes to be irradiated until one outgoing call ends is up to 6000 times, resulting in an increase in call processing load and deterioration in call processing performance.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to minimize the number of times the incoming call code and the registered incoming code to collect the incoming code statistics data to minimize the call processing load. The present invention provides a method for retrieving a minimum ringing code of a mobile communication exchange which reduces the number of times and improves the performance of the system.

In order to achieve the above object, the minimum incoming code search method of the mobile communication switch according to the present invention,

Calling a statistics library to determine if the statistics library is a first statistical event; Assigning a terminating code index to a call register if the statistical library is a first statistical event; If the statistical library is not the first statistical event, the outgoing call statistics library and the incoming code statistics library are constituted by one library.

Hereinafter, an embodiment according to the technical idea of the method for retrieving the minimum incoming code of the present invention configured as described above will be described in detail.

3 is a flowchart illustrating a method of searching for a minimum incoming code of a mobile communication switch according to the present invention.

As shown therein, calling the statistics library to determine whether the statistics library is the first statistical event (ST11); Assigning an incoming code index to a call register if the statistical library is the first statistical event (ST13-ST15); If the statistics library is not the first statistics event, the outgoing call statistics library and the incoming code statistics library are configured as one library (ST16 to ST19).

In the step of determining whether the statistics library is the first statistical event by calling the statistics library (ST11), whenever a defined statistics event occurs, the called statistics library is called and the outgoing occupation is the first event. It is characterized by determining whether it is a request event.

In the above, the statistical library is defined as one statistical library capable of processing both outgoing call statistics and incoming code statistics, and when using the library, one of the input parameters is defined as outgoing incoming call prefix and the statistical library. Characterized in that it is possible to check whether the code entered in the registered incoming code.

In the above, the statistical library is characterized by using a call register having a unique value as an input variable in the processor in which the call is generated as a specific area in the memory generated whenever a call occurs.

In the above, the statistics library has a request for outgoing occupancy, which is the first statistical event, and is characterized in that it is possible to examine the registered incoming code when the statistics library is called.

The step of assigning the destination code index to the call register (ST13-ST15), the step of comparing the incoming destination code and the registered incoming code if the statistics library is the first statistical event (ST13); Comparing the received destination code with the registered destination code and storing the obtained destination code index in a corresponding area of the call register (ST14); And storing the obtained called code index in the corresponding area of the call register, and then recording and returning the first statistical event (ST15).

In step (ST16-ST19) of configuring the outgoing call statistics library and the incoming code statistics library as one library, the incoming code index corresponding to the value of the corresponding call register is set if the input statistical event is not the first statistical event. Checking whether it is a positive value (ST16); If the called code index is a positive value, recording a called code statistical event in an area corresponding to the called code index (ST17); If the called code index is a negative value or if the called code statistics event is recorded in the area corresponding to the called code index, it consists of the steps of recording and returning the outgoing call statistics event (ST18) (ST19).

In the above index value, if the index value is positive, the incoming code statistical data can be generated from the positive index value thereafter. If the index value is negative, the incoming call code and all registered incoming codes are different from the first digit. It is characterized by displaying that.

Referring to the accompanying drawings, the operation of the minimum incoming code search method of the mobile communication switch according to the present invention configured as described above will be described in detail as follows.

First, a statistical event occurs at the same time point as the incoming code statistics. Therefore, as in the conventional method, instead of separately configuring the outgoing call statistics library and the incoming code statistics library, one statistical library that can handle both outgoing call statistics and incoming code statistics is defined. When using this library, one of the input parameters is defined as outgoing called code prefix to check whether the code entered in the statistics library is a registered called code.

The statistics library also uses the call register as an input variable. The call register is a specific area in memory that is created each time a call occurs and has a unique value within the processor from which the call originated. Because the call register value is unique, the statistics library has the first statistical event, the outgoing occupancy request (Attempt), and it examines the registered incoming code when the statistics library is called. The result of the investigation is that the index is stored in the same position as the call register in the destination code index array where the array is equal to the total number of call registers.

Here, the stored index value having a negative value means that the incoming called code and all registered incoming codes are wrong from the first digit. If the index value has a positive value, the incoming code statistical data can be generated from this index value thereafter.

The flow of the library function according to this is as follows.

First, the statistics library is called to determine whether the statistics library is the first statistics event. That is, whenever a defined statistical event occurs, the statistical library is called to determine whether the called statistical event is the first event, outgoing occupation request event (ST11) (ST12).

So if the statistics library is the first statistics event, it assigns the destination code index to the call register. If the statistics library is the first statistical event, it compares the incoming call code with the registered incoming code (ST13), stores the obtained call code index in the corresponding area of the call register (ST14), and records the first statistical event. It performs by returning (ST15).

If the statistics library is not the first statistics event, the outgoing call statistics library and the called code statistics library will be organized into one library. That is, if the input statistical event is not the first statistical event, it is examined whether the incoming code index corresponding to the value of the call register is a positive value (ST16). Thus, if the called code index is a positive value, the called code statistics event is recorded in the area corresponding to the called code index (ST17). If the called code index is a negative value or if the called code statistical event is recorded in the area corresponding to the called code index, the outgoing call statistics event is recorded and returned (ST18) (ST19).

As such, the present invention reduces call processing load by minimizing the number of comparisons between the incoming terminating code and the registered terminating code in order to collect the terminating code statistical data.

As described above, the minimum incoming code search method of the mobile communication switch according to the present invention does not check whether the corresponding incoming code is a registered incoming code whenever a defined incoming code statistics event occurs and is the first incoming statistical event. By checking whether the incoming code is registered only, the effect on the load of the call processing is reduced to one fifth compared to the conventional method, thereby improving the call processing performance.

In addition, the present invention also has the effect of improving the performance of the system by reducing the load impact on the call processing because the statistics library is not called by configuring the outgoing call statistics library and the incoming code statistics library as one library. do.
