Abstract

The present invention relates to a method of unifying operations of a plurality of boards in a CDMA communication system by using logical addresses of the boards. Conventionally, since a board with a physical slot ID must be attached to a slot of the system corresponding to the physical slot ID, the board cannot be recognized by the system if it is attached to another slot of the system. In the present invention, a board is attached to a slot of the system on the basis of a logical address of the board, which is stored in a board configuration information. According to the present invention, since a board can be attached to any slot of the system regardless of the physical slot ID of the board, the boards can be easily managed.

[17] It will be readily understood that the components and steps of the present invention, as generally described and illustrated in the Figures herein and accompanying text, could be arranged and designed in a wide variety of different configurations while still utilizing the inventive concept. Thus, the following detailed description of the preferred embodiments of the method of the present invention, as represented in Figs. 1 through 6 and accompanying text, is not intended to limit the scope of the invention, as claimed, but it is merely representative of the presently preferred embodiments of the invention. The presently preferred embodiments of the invention will be best understood by reference to the drawings, wherein like parts or steps are designated by like minerals throughout.

[18] The present invention unifies operations of a plurality of boards in a CDMA communication system by using logical addresses of the boards, even if the boards are different from each other in form as in the case of an IBS package (CDMA-2000 lx InBuilding system) and 3G-1XWILL system.

[19] The logical slot ID that corresponds to the physical slot ID is predefined and fabricated into a PLD (p-bsm) in order to unify the operations of two systems which are different from each other in terms of form.

[20] The fabricated PLD comprises a board configuration information of a physical slot ID, a physical Shelf ID, a board type, a logical slot ID, etc., and manages the BSM. When the CCP requests the board configuration information while being initialized, the MSLA that is a BSM loader reads the PLD. It then extracts the necessary board configuration information and downloads the information to the CCP.

[21] The operations of the above will be described in further detail as follows.

[22] Fig. 1 illustrates the flow of unifying operations of a plurality of boards in a CDMA system by using logical addresses of the boards.

[23] Where, reference mineral 100 denotes a Base Station Manager (BSM) having a BSM System Loader Application (MSLA); reference nimeral 200 denotes a Call Control Processor (CCP) having a CCP Operating System Block (CCOS) 210, a Common Block Loader Application (XBLA) 220 and a CCP Loader Application (CCLA) 230; and reference nimeral 300 denotes an Enhanced Vocoder execution Asseirbly (EVXA) having a CCP EVXA Operating System Block (CSOS) 310 and a Common Block Loader Application (XBLA) 320.

[24] A method for unifying operations of a plurality of boards in a CDMA communication system will be described in detail as follows.

[25] First, in step S102, CCOS 210 requests board configuration information (for example, a physical slot IP, endvpi, etc) to MSLA 110. In step S102, MSLA 110 searches the PLD, extracts the board configuration information, and transmits the information to CCOS 210.

[26] Then, in step S 103, CCOS 210 sets an ATM address table by using a logical ID among the received board configuration information and runs XBLA 220 after setting of the ATM address table.

[27] In step S 104, XBLA 220 requests loading to MSLA 110 by using the logical ID of each board.

[28] In step S105, CSOS 310 requests the board configuration information to CCOS 210; and in step S106, CCOS 210 transmits the board configuration information to CSOS 310.

[29] In step S 107, XBLA 220 requests loading to MSLA 110; in step S 108, MSLA 110 loads the request information to XBLA 220; and in step S109, XBLA 220 executes CCLA 230.

[30] In step SI 10, CSOS 310 requests BSC ID to CCLA 230; in step Si l l, CCLA 230 transmits BSC ID to CSOS 310; and in step SI 12, CSOS 310 executes XBLA 320.

[31] Then, in step SI 13, XBLA 320 requests loading to CCLA 230; and in step SI 14, CCLA 230 loads the requested information to XBLA 320.

[32] Fig. 2 illustrates the loading process of applications frcxn the CCP to the BSM by using logical addresses of the boards; and Fig. 3 illustrates the loading process of applications from the CCP to the EVXA by using logical addresses of the boards.

[33] As described in Figs. 2 and 3, the flow comprises step S211 to step S213 that requests board configuration information to BSM 100, determines whether the received board configuration information is exact or not, and sets an ATM address table by using the received board configuration information; step S214 that requests loading to BSM 100 by using the address table; step S215 that executes a main loader upon receipt of loading frcxn BSM 100; step S216 that requests loading of CCP applications to BSM 100 from the main loader; step S221 to step S222 that determines whether the board configuration information is requested frcxn BSM 100 and transmits the board configuration information transmitted frcxn BSM 100 to CSOS 310; step S223 to step S224 that determines whether a BSC ID is requested from CSOS 310 and transmits the BSC ID to CSOS 310; and step S225 to step S226 that determines whether loading of EVXA applications is requested and loads EVXA applications according to the request frcxn EVXA 300.

[34] The steps of Figs. 2 and 3 will be described in further detail as follows.

[35] CCP 200 requests board configuration information to BSM 100 in step S211, and determines whether the received board configuration information is exact or not in step S212. It then sets an ATM address table by using the received board configuration information when the board configuration information is received correctly in step S213. [36] Then, XBLA 220 requests loading to BSM 100 by using the address table in step S214 and executes a CCP main loader upon receipt of loading frcxn BSM 100 in step S215. [37] Then, CCLA 230, which is the main loader, requests loading of CCP applications to BSM 100 in step S216. [38] Subsequently, when the board configuration information is requested frcxn BSM 100 in step S221, the board configuration information received frcxn BSM 100 is transmitted to CSOS 310 in step S222. [39] A BSC ID is then requested from CSOS 310 in step S223; the BSC ID is transmitted to CSOS 310 in step S224, and when loading of applications frcxn EVXA is requested in step S225, EVXA applications are loaded according to the request frcxn EVXA 300 in step S226. [40] Fig. 4 illustrates the loading process of applications frcxn the BSM to the CCP by using logical addresses of the boards. [41] As described in Fig. 4, the flow comprises step S311 to step S312 that determines whether the board configuration information is requested frcxn CCOS 210 and reads the PLD and transmits the board configuration information that is suitable in form to CCOS 210; step S313 to step S314 that determines whether loading of applications is requested frcxn XBLA 220 in CCP 200 and loads applications according to the request; and step S315 and step S316 that determines whether loading of CCP applications is requested frcxn CCLA 230 in CCP 200 and loads CCP applications according to the request from CCLA 230. [42] The steps of Fig. 4 will be described in further detail as follows.

[43] CCOS 210 requests board configuration information in step S311; and BSM 100 reads the PLD and transmits the board configuration information that is suitable in form to CCOS 210 in step S312. [44] When loading of applications is requested frcxn XBLA 220 in CCP 200 in step S313, the applications are loaded according to the request in step S314. [45] Then, when loading of CCP applications is requested frcxn CCLA 230 in CCP 200 in step S315, CCP applications are loaded according to the request frcxn CCLA 230 in step S316. [46] Fig. 5 illustrates the loading process of applications frcxn the EVXA to the CCP by using logical addresses of the boards. [47] As described in Fig. 5, the flow comprises step S411 to step S413 that the board configuration information is requested to CCOS 210, determines whether the requested information is received correctly, and the BSC ID is requested to CCLA 230; step 5414 that sets an ATM address table based on the BSC ID and the board configuration information when the requested BSC ID is received and runs XBLA 320; and step 5415 that loading of EVXA applications is requested to CCLA 230 from XBLA 320. [48] The steps of Fig. 5 will be described in further detail as follows.

[49] EVXA 300 requests the board configuration information to CCOS 210 in step 5411. When the requested board configuration information is received correctly in step 5412, the BSC ID is requested to CCLA 230 in step S413.

[50] Then, the ATM address table is set based on the BSC ID and the board configuration information when the requested BSC ID is received and XBLA 320 is run in step S414.

[51] Thereafter, XBLA 320 requests loading of the EVXA applications to CCLA in step S415. Industrial Applicability
