Description

How to check for abnormality of program load data

The present invention relates to a Digital Cellular System (DCS) and a Personal Communication Systems (PCS) using Code Division Multiple Access (CDMA). In particular, the present invention relates to a method for verifying program load data (PLD) for operation and maintenance of an operating base station controller (BSC) and a base station transceiver system (BTS).

In a conventional system, there are programs loaded and executed on a system, and program load data storing shapes and operational data of each system. In the same program, it is possible to operate the system according to each characteristic according to the contents of program load data.

1 is a block diagram of program load data to help explain the present invention. The program load data of the code division multiple access system is composed of a base station manager (BSM), a call control processor (CCP) and a base station control processor (BCP), and exists in a predetermined memory space. . As shown in FIG. 1, the upper system stores lower data. Accordingly, when changing the program load data, the stored data must be changed together with the data being operated.

Conventionally, when there is a problem during operation, it is necessary to check whether three data of the base station manager, the call control processor, and the base station control processor match or have correct data. The base station manager's data can be viewed using a Display command on a MMC (Man Machine Command). However, data from the call control processor and the base station control processor can only be viewed by entering a command on the terminal via a cable (RS-232C).

The base station control processor could remotely enter commands even when the base station system was far from the operator, but the call control processor could not enter remote commands.

In the case of a call control processor, in order to view the data, only a person who knows the entire structure and contents of the program load data can enter the command to see the data, so it is very difficult for the operator (or any other developer) to see the data. It was difficult, and even though I could see it, I could only see certain data.

Therefore, there was a problem that it is difficult to check the overall program load data. It was also impossible to examine the data of the entire program load data.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for checking whether there is an abnormality of program load data for verifying overall program load data in operation in a system of code division multiplexing.

Other objects and advantages of the present invention will become more apparent from the following detailed description of the invention and the accompanying drawings.

It should be understood to include.

Hereinafter, a method of checking whether there is an abnormality by comparing the program load data in operation of the present invention will be described with reference to FIGS. 2 to 4.

According to the present invention, a method of checking whether there is an abnormality of program load data is made by using a MMC (Man Machine Command), so that program load data of a desired call control processor and a base station control processor can be examined even while operating a system.

In the embodiment of the present invention, when the base station manager 101 issues a command to the call control processor 102, whether the program load data of the call control processor 102 or the program load data of the base station control processor 103 are desired. Signals are specified by CCP_ID and BCP_ID to distinguish them. After the command is executed, the program load data file is created in the directory (p_CCPxx, p_BCPxxyy). The program load data read into the base station manager can be compared with each other using the program load data tool (Tool) to compare with each other as a whole, the system operator may only see the contents of the data.

2 is a block diagram illustrating an operation of a base station manager for checking whether there is an abnormality by comparing program load data according to an embodiment of the present invention.

In another embodiment of the present invention, the base station manager requests program load data from the call control processor (201), and thus an application in charge of loading the call control processor receives the request of the base station manager. do. The base station manager checks whether the program load data has been normally transmitted (202), and writes the program load data into the buffer (203) when the normal transmission is completed.

The sequence number 204 and the error checking signal 205 are compared with the program load data to complete transmission of the program load data in operation. In this case, if it is not the same after the comparison, the maximum number of retries is checked (206), and the program load data is requested again (207).

The application of the call control processor first determines whether the request signal of the program load data requires the program load data of the call control processor or the program load data of the base station control processor.

At this time, the judgment is classified into the signal type. That is, if the signal requesting the program load data of the call control processor recognizes the CCP_ID, if the signal requesting the program load data of the base station control processor recognizes the BCP_ID and processes to transmit the corresponding program load data, respectively.

3 illustrates an operation of a call control processor for examining program load data of a call control processor according to an embodiment of the present invention.

When the signal of the base station manager requests the program load data of the call control processor, it is first checked whether the data size is greater than zero (301). If 0 or less, the base station manager sends a complete signal (Complete Signal) (307).

If greater than zero, the program load data of the call control processor is divided into a maximum transmission size (200 bytes) that can be transmitted at a time, and the divided program load data data, a sequence number, and an error checking signal are checked. Send to the administrator (302). In operation 303, a response signal for data transmission is received from the base station manager.

The base station manager compares the sequence number delivered with the program load data from the call control processor (304), checks the maximum number of attempts if different (305), then increments the retry count (MAX_RETRY_CNT) by one (306), and receives the program load data. Retry

If the comparison result is the same, the sequence number is increased by one (308), and the data size is decreased (309) to confirm the received data.

4 illustrates an operation of a call control processor for examining program load data of a base station control processor according to an embodiment of the present invention.

In another embodiment of the present invention, if the signal of the base station manager requests program load data of the base station control processor (401), first it is checked whether the data size is greater than zero (402). If 0 or less, the base station manager sends a data complete signal (Complete Signal) (409). If greater than zero, the call control processor transmits a request signal of program load data to the application responsible for loading the base station control processor (403).

The application in charge of loading the base station control processor transmits a response to the request signal of the program load data (404), and divides the program load data into a maximum size (200 bytes) that can be transmitted at once and sends it to the control processor.

When receiving the signal that the transmission is normally transmitted (405), the application in charge of loading the call control processor receiving the program load data, the sequence number and the error checking signal transmits the data (Bypass) to the base station manager (406). . The base station manager confirms receipt of program load data from the call control processor (412). If the result of the check is abnormal reception, the number of retry attempts is checked (407), and the number of retry signals MAX_RETRY_CNT is increased by one (408).

At this time, the program data transmitted in sequence according to the sequence number is compared. When the first program data is transmitted, the sequence number is reduced after comparison, and then the program data of the next sequence number is requested. The call control processor 102 then transmits the next sequence number of program data, the base station manager compares and reduces the data size (411) to recognize the progress of the program load data. When the program data of the last sequence number is compared, the data size becomes 0, and the base station manager 101 senses that all program load data has been processed, and ends the comparison / confirmation execution.

According to the present invention operating as described above, it is possible to easily check the program load data by comparing the program load data in operation to check whether there is an abnormality, and to improve the characteristics of easily comparing and analyzing the program load data between systems.
