The present invention relates to a method for loading a driving program of a mobile communication system. In particular, the BSM of a mobile communication system initializes the system by first loading the driving program data for the BSC without loading all the driving program data into the lower BSC, and then rests the lower board. The present invention relates to a method of loading a driving program of a mobile communication system for loading and initializing driving programs of a lower BTS.

In general, cellular phones, in particular, in the early 1980s, divided the service area into hexagonal cells of several km to several ten kilometers in diameter in North America, and then repeatedly used the same frequency channel in geographically separated cells. According to the movement, the cellular-phone, which implements the radio channel switching function between cells, has grown rapidly due to the first commercialization. In addition, such a cellular phone generally includes a plurality of mobile communication base stations for a subscriber having a terminal to smoothly communicate with other communication subscribers in a long distance using a mobile communication network. In accordance with the instructions of the control station transmits and receives the signal of the terminal amplified to a predetermined level and then connected to the desired communication network.

Then, referring to the conventional mobile communication system as described above with reference to FIG. 1, a base station that performs call control and maintenance functions for allocating traffic channels and opening a call path for call requests of terminals 70 (hereinafter referred to as BTS) (BASE STATION TRANSCEIVER SUBSYSTEM; 71)] and the BTS (71) and PSTN LE (LOCAL EXCHANGE, hereinafter referred to as LE) to perform a function to support the setting / release of outgoing and incoming calls, and wireless section QUALCOMM CODE EXCITED LINEAR PREDICTION (QCELP), PULSE CODE MODULATION (PCM) And a base station controller (BSC (BASE STATION CONTROLLER); 72A-N] that performs a matching function with the PSTN LE and initialization, downloading, state management, and configuration management for the BSCs 72A-N and BTS 71. , Fault management, performance statistics and operator matching, subscriber authentication function, etc. Operating system section for performing [BSM (BASE STATION MANAGER) referred to; 73; consists of.

Here, the BSM 73 of the mobile communication system is first manufactured and loaded with a driving program in the lower BSCs 72A-N or BTSs 71 before installation or maintenance. You must initialize it.

Meanwhile, referring to the driving program loading method of the conventional mobile communication system as described above, when the BSM 73 receives a signal for requesting to download the driving program from the lower BSCs 72A-N, the received BSC is received. First, only one of the self-driving programs such as an operating program (OS) or an application (APP), a package list table of subprocesses, and a driving program of the lower BTS 71 is applied to any one of the 72As. All of them are downloaded and stored in the memory in sequence, and then the corresponding BSC 72A is initialized using these driving programs. At the same time, the lower processor and the lower BTS 71 of the BSC 72A are sequentially initialized to wait for call processing. Enter the state.

At this time, the downloading operation of the drive program of the BSM 73 is executed by only one BSC 71A in terms of hardware structure.

However, in the conventional method of loading a driving program of the mobile communication system, when downloading a driving program from a BSM to a specific BSC, a self-driving program such as an operating program (OS) or an application (APP) and subprocesses The downloading process of BSM was very slow because all of the package list table and the driver programs of the lower BTS 71 were downloaded all at once. If such a download operation is long, the time for initializing the remaining BSCs is increased by that much, thus maintaining the reliability of the mobile communication system.

Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, and the loading program of the mobile communication system significantly improves the loading processing speed accordingly because the BSC drive program and the lower drive program are separated and loaded. The purpose is to provide.

Another object of the present invention is to provide a method for loading a driving program of a mobile communication system, which can rapidly process driving of lower BSCs without additional system changes, thereby significantly improving the maintenance characteristics of the mobile communication system.

The present invention for achieving the above object is the BSC boot area loading process of initializing only the boot area of the BSC by loading only the kernel data to the lower BSC that the BSM of the mobile communication system has requested the program loading, and the BSC boot area loading After the process, the BSM checks whether there is a kernel data loading request from a BSC other than the BSC which loaded the kernel data, and if there is a loading request, the other BSC loading request confirmation process for executing the BSC boot area loading process; If there is no loading request of kernel data from other BSC during the process of checking other BSC loading request, the BSM loads the program for the lower board and lower BTS of the relevant BSC to the BSC loaded with the kernel data and initializes them. It provides a driving program loading method of the mobile communication system consisting of.

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

The mobile communication system to which the present invention is applied includes a BTS 2 that performs call control and maintenance functions for allocating traffic channels and opening a call path for call requests of terminals 1, as shown in FIG. The BSC performs a function of matching with the BTS 2 and the PSTN LE (hereinafter referred to as LE) to set / release a call and an incoming / outgoing call and execute initialization using a separately downloaded driving program. 3A-N), the self-driven program of the BSC (3A-N) and the drive program of the remaining lower processor or BTS (2) are separately loaded, and the status management, configuration management, fault management, performance statistics and operators It consists of a BSM 4 that performs matching, subscriber authentication functions, and the like.

Here, the BSM 4 is provided with a BDSM (BSM Down Loder) that is responsible for packaging loading. The BSC 3A-N includes a BSLU (BSC Loading Unit) 5 for loading a program into the BSM 4, an SBP (Selector Bank Processor) 6 for selecting a driving program from the BSLU 5, And a selector and vocoder channel (SVC) 7 initialized using the drive program selected by the SBP 6. In addition, the BDNL 8 of the BSM 4 is a thread in charge of loading on the BSM, and the BSLU 5 is a process block in charge of loading on the CCP 9.

Next, the method of the present invention applied to the above apparatus will be described.                     

The method of the present invention proceeds from the initial state S1 to the kernel data processing step S2, as shown in FIG. 3, and requests for self-driving data for initializing kernel data, i.e., its basic hardware, from any BSC. Receive the signal. After the kernel data processing step (S2), the process proceeds to the loading operation determination step (S3) to determine whether there is more than one BSC currently being loaded. At this time, as a result of the determination in the loading operation determination step (S3), if there is more than one BSC currently being loaded, the current state ends and proceeds to the standby state. However, if it is determined during the loading operation determination step (S3) that there is no BSC currently being loaded, the process proceeds to the kernel data loading preparation step (S4) and the BSM initializes flags for the lower devices of the BSC. The data information to be loaded is transmitted in advance. In addition, after the kernel data loading preparation step (S4), the process proceeds to the kernel data loading step (S5) so that the BSM loads the kernel data into the corresponding BSC. After the kernel data loading step (S5), the process proceeds to the BSC boot data initialization execution step (S6) to initialize the basic boot region of the corresponding BSC using the kernel data downloaded from the MSC.

On the other hand, after the BSC boot data initialization execution step (S6) proceeds to the loading request judging step (S7) to determine whether a download request signal is received from another BSC that has not currently downloaded the kernel data. At this time, when the downloading request signal is received from another BSC that has not downloaded the current kernel data as a result of the determination during the loading request judging step (S7), the process proceeds to the kernel data loading preparation step (S4) and repeats the loop. do. However, if it is determined during the loading request judging step (S7) that the download request signal is not received from another BSC that has not downloaded the current kernel data, the process proceeds to the lower device loading request signal determining step (S8) and the current kernel. It is determined whether a signal for requesting the loading of the driving program for the lower equipment is received from the BSC in which the data is downloaded. In this case, if the signal for requesting the loading of the driving program for the lower device is not received from the BSC from which the current kernel data is downloaded as a result of the determination during the lower device loading request signal determining step (S8), the current step ends and is in a standby state. Proceed. However, if a signal for requesting the loading of the driving program for the lower device is received from the BSC from which the current kernel data is downloaded, the process proceeds to the lower device data loading step (S9) and the BTS initializes the kernel using the kernel data. Download the running program for the lower processor and lower BTS. After the lower device data loading step (S9), the process proceeds to the loading request repetition determination step (S10) to determine whether a download request signal is received from another BSC not currently downloading kernel data. In this case, when the downloading request signal is received from another BSC that does not download the current kernel data, the process proceeds to the kernel data loading preparation step (S4) and repeats the loop. Wait for the kernel data loading operation of the relevant BSC to end. However, if the downloading request signal is not received from another BSC that does not download the current kernel data, as determined by the loading request iterative decision step (S10), the process proceeds to the lower device initialization execution step (S11) and the BMS is currently initialized. Initializes both the processor board below the BSC and the BTS connected to the BSC by using the downloaded driving program.                     

In other words, the loading procedure between the BDNL 8 of the BSM 4 and the BSLU 5 of the BSC 3A-N can be largely divided into three parts.

The first part is loading OS, APP, PLD which is KERNEL for driving CCP block 9, the second part is loading package information table of lower process blocks, and the last part is lower package based on table. CODE part to load.

Accordingly, the BSLU 5 separates the table and the lower package loading part in the process of loading, and the BDNL 8 manages the state of the BSLU 5 of each BSC 3A-N. . Therefore, unlike the related art, the BSM 4 first transfers only kernel data to the CCP 9 of the corresponding BSC 3A-N. In this case, the BDNL 8 receives the kernel from the booter of the BSC 3A-N. Receives Loading Request (0xCE2) and performs Kernel Loading. Here, the BDNL (8) manages by limiting the maximum loading count (Current Loading Count) that can be performed simultaneously to less than 2, by checking the index currently loaded when the request of the Kernel Loading Request received during the loading process If it is less than 2, create a loading child to execute kernel loading. If it is more than 2, ignore the request signal.

On the other hand, the Booter of the BSC 3A-N periodically transmits a request until a PrCheck is received from the BDNL 8 that receives the Kernel Loading Request. The BDNL 8 manages the lower Loading Flag of the BSC 3A-N as N_DEF / ENABLE / DISABLE and initializes the lower Loading Flag of the BSC 3A-N that requested initial loading to N_DEF. The BSLU 5 of the BSC 3A-N performs a booting process by driving program data for self-driving, for example, OS / APP / BSLU, loaded by Kernel Loading.

In addition, the BSLU 5 of the BSC 3A-N initializes the CCP block by using the kernel data loaded first, and then PL loads a package for a lower process block, for example, SBP 6 or SVC 7. Send to BSM 4 as Table Request (0xAA1). The BDNL 8 of the BSM 4 then transmits the PL Table No and Entry Information to the BSLU 5 of the BSC 3A-N.

Accordingly, the BSLU 5 of the BSC 3A-N sends a CD Loading Request (0xAA2) to the BDNL 8 when the PL Table has finished loading. At this time, the BDNL 8 disables the lower Loading Flag when the received Current loading count is 1 or more and transmits a Block Loading Wait (0xD50E) to the BSLU 5 of the BSCs 3A-N. Then, the BSLU 5 stops loading the code until the BDNL 8 transmits a Block Loading Act (0xACB) or the Waiting Timer (3 minutes) is exceeded and resends the CD Loading Request. At this time, if the BDNL 8 checks the Current Loading Count and is less than 1, the lower Loading Flag is enabled and the CD CodeStart (0xD506) is transmitted.

Then, the BSM 4 ends by loading data for all lower blocks on the table into the corresponding BSC 3A-N. At this time, the terminated BSLU (5) transmits the CD OK (0xD50a), and the BDNL (8) receiving the received BSC (3A-) to search the lower Loading Flag to the Current Loading Count is less than 2 and disabled in the lower Loading Flag If N) is present, the Code Loading is performed by sending the Block Loading Act (0xACB) to the BSLU.

Therefore, the above process is repeated, so that other BSCs execute the same program loading operation.

As described above, the present invention initializes the system by first loading the drive program data for the BSC without loading all the drive program data into the lower BSC in the BSM of the mobile communication system and then loading the drive programs of the remaining lower boards and the lower BTSs. By initializing it, the BSC drive program and the lower drive program are separated and loaded, thereby having an advantage of significantly improving the loading processing speed.

Further, according to the present invention, since the operation of the lower BSCs is quickly processed without additional system change, the maintenance characteristics of the mobile communication system are also significantly improved.
