Abstract

PURPOSE: A method for loading software in a mobile communication system is provided to load a software file compressed from a CCP(Central Control Processor) through a target processor when loading software required for a system operation, thereby using efficiently communication path resources through the reduction of loading packets. CONSTITUTION: A target processor requires a software loading to a CCP(ST11). The CCP transmits information on the requested software to the target processor(ST12). Then the target processor transmits a response signal to the CCP(ST13). Thereafter, the CCP analyzes the corresponding software(ST14) and discriminates whether the compression of files is performed, in case that the size of the software is large or in case there are many software versions(ST15). When a file compression is performed, the size and numbers of the software versions are shortened or reduced(ST16). If the file compression is unnecessary, the corresponding software is read and then transmitted to the target processor(ST17). Then the target processor checks whether the transmission is completed(ST18) and then transmits the check result to the CCP(ST19). Thereafter, the target processor checks whether the loaded file is compressed(ST20). When the loaded file is compressed, the file is decompressed(ST21) and stored to a memory(ST22). Thereafter, the corresponding software is operated(ST23).

Description

Method for loading of software in mobile communication system

The present invention relates to a method for improving loading speed using software file compression in a mobile communication system to reduce the time required for software loading required for system operation in a mobile communication system. By loading the compressed software file, it is possible to efficiently use the communication path resources through the reduction of the loading packet, and the loading time can be shortened by reducing the size of the software through the compression, thereby resulting in faster service start-up. The present invention relates to a method for loading software in a mobile communication system.

FIG. 1 is a schematic diagram illustrating a process of performing software loading in a general mobile communication system, and FIG. 2 is a diagram illustrating a step of loading a software in the mobile communication system according to FIG. 1.

As shown in FIG. 1, when the system is initially started, the base station management (BSM) 200 performs loading according to a loading request of the central control processor (CCP) 110.

In this case, the software for loading the CCP 110 is the software required for the CCP 110, PLD (Programmable Loading Data), and the target to be loaded in the CCP 110 as shown in FIG. (Target) A PLD to be loaded on a processor (for example, a BTS control processor 120) and software are loaded.

In addition, the software to be loaded by the target processor 120 of the CCP 110 to its target processor is also loaded.

Here, the software to be loaded on the CCP includes the software required for the CCP, the software of the PLD and the target processor to load the CCP, and the software to the PLD and the target processor of the CCP to load the target processor.

In addition, the software loaded on the target processor of the CCP includes software required for the target processor, PLD, and software for the target processor to load the target processor.

It also includes software that is loaded on its target processor that the target processor performs loading and software required for the target processor.

Meanwhile, when the loading of the CCP 110 is completed, the CCP 110 may load the software and the PLD to be loaded on the target processor 120 and the target processor 120 according to the loading request of the target processor 120. Perform software loading of the target processor (eg channel card).

In this way, loading is performed up to the final lower target board 130.

That is, the same software is continuously transmitted through the communication path until the loading to the final lower target board 130 is performed by the above-described method.

Therefore, in the above structure, since the mobile communication system is complicated and diverse, the size of the software is increased and the number of software is increased. Therefore, the loading time required for restarting the system is consumed, so the restart time becomes long.

Accordingly, the present invention is proposed to solve the above problems of the prior art,

An object of the present invention is to load the software files compressed from the central control processor (CCP) in the target processor when loading the software required to drive the system in the mobile communication system, so that the communication path resources can be efficiently used through the reduction of loading packets In addition, the present invention provides a method for loading a software in a mobile communication system that can reduce the size of software through compression and thus reduce loading time.

Hereinafter, a preferred embodiment of the "software loading method in a mobile communication system" of the present invention according to the above technical concept will be described in detail with reference to the accompanying drawings.

3 is a diagram illustrating a step-by-step software loading process in a mobile communication system according to the present invention.

As shown here, since software loading is carried out in a mobile communication system, the same software is stored in several stages of processor memory to transfer the software to its final destination.

When the size of the stored software is reduced by using a compression algorithm, the number of packets is naturally reduced during loading. Reduction of the loading packet uses less resources of the communication path and can deliver software to a destination, and decompresses the compressed software using a decompression algorithm at the last destination and stores the decompressed software in memory. It is completed by doing.

Here, the software to be loaded in the CCP includes software required for the CCP, compressed software of the target processor to perform loading in the PLD, and the CCP, and software for the target processor of the PLD and CCP to perform the compressed loading to their target processors. .

In addition, the software loaded on the target processor of the CCP includes compressed software and PLD required for the target processor, and compressed software for the target processor to load the target processor, wherein the compressed software and the PLD are decompressed. It operates after saving to memory using algorithm.

In addition, the software loaded on the target processor that the target processor performs loading includes the software required for the target processor. Here, the compressed software is operated after being stored in a memory using a decompression algorithm as described above.

The loading process will be described in more detail with reference to FIG. 4 as follows.

4 is a flowchart illustrating a software loading method in a mobile communication system according to the present invention.

As shown therein, step ST11 of requesting software loading from a target processor to a central control processor (CCP), step ST12 of transmitting information on the requested software from the CCP to a target processor, and In step ST13, when the information of the software is transmitted, the target processor transmits a response signal to the information, and analyzes the corresponding software in the CCP that receives the response signal (ST14). Step ST15 of determining whether or not to compress the file; and step ST16 of compressing the files so as to reduce the size or number of the software files when performing the compression as a result of the determination; Reading the corresponding software and transmitting it to the target processor; A step ST19 of checking whether or not the target processor has received the transmission is completed and transmitting the success to the CCP; and after the transmission, a step ST20 of checking whether the loaded file is compressed by the target processor; If the check result is compressed, decompressing the loaded software files (ST21), and storing the result in the memory. If the check result is not compressed, immediately saving the memory in the memory. Thereafter, step ST23 is provided to operate the software.

In other words, when the target processor requests loading into the CCP (ST11), the CCP that has requested the loading delivers information on the size and packet number of the software requested by the target processor (ST12).

The target processor receiving the information transmits a response signal to the information to the CCP (ST13).

Upon receiving the response, the CCP reads the software stored in the memory (ST14) and performs compression according to whether or not the file is compressed (ST15) (ST16) and transmits it to the target processor (ST17).

On the other hand, when the transmission of the software is completed, the target processor notifies the CCP of the success or not (ST18) (ST19), and checks whether the received software is compressed (ST20) and operates the decompression algorithm if it is compressed (ST21). If it is not compressed, the software is immediately stored in memory (ST22) to operate the software (ST23).

According to the above-described "software loading method in the mobile communication system" according to the present invention, by compressing the software when performing the software loading in the mobile communication system, it is possible to reduce the number of loading packets, thereby reducing the efficiency of limited communication path resources It has the advantage of preventing the use of unnecessary and occupying unnecessary resources and improving the loading speed.

In addition, the reduction of the loading time has an effect of reducing the system service start preparation time.
