[0039] As shown in FIGS. 2, 3, and 4, the first embodiment of a method for interfacing a rate adaptation processing unit (RAPU) 10 with a board messenger processing unit (BMPU) 20 in a wireless data communication processing device according to the present invention , The method includes the following steps:

[0040] In steps s20 and s90, in response to protocol data (PD) transmitted from one communication system to another communication system, a common header field and an information field are formed in a predetermined area of ​​the data buffer, where the common header field includes Figure 2b with Figure 3b The rate adaptation (RA) header and the board message (BM) header are shown, and the common header field can be shared by the rate adaptation (RA) protocol data (RAPD) and the board messenger protocol data (BMPD);

[0041] In steps s30 and s100, the protocol offset and protocol data are stored in the common header field and the information field, respectively.

[0044] As shown in Figure 2 andFigure 4 As shown, the second embodiment of the method for interfacing a rate adaptation processing unit (RAPU) with a board messenger processing unit (BMPU) in a wireless data communication processing device according to the present invention includes the following steps:

[0045] In step s10, the rate adaptation receiving unit (RARU) of the rate adaptation processing unit (RAPU) receives the protocol data (PD) through the rate adaptation interface (RAI).

[0046] In step s20, a data buffer is allocated according to the received protocol data. A common header field and an information field are formed in a predetermined area of ​​the data buffer. The common header field can be shared by rate adaptation (RA) protocol data (RAPD) and board messenger protocol data (BMPD), where the common header field includes rate adaptation Configuration (RA) header and board message (BM) header.

Abstract

A method for interfacing between a rate adaptation processing unit (RAPU) and a board messenger processing unit (BMPU) in a wireless data communication processing apparatus is disclosed, wherein the method includes the following steps: forming common header in a first address of an allocated data buffer, the common header being usable commonly by a rate adaptation (RA) protocol data (RAPD) and a board messenger (BM) protocol data (BMPD) when the respective protocol data (PD) is received through the interfacing of the RAPU or the BMPU; storing the received PD in an information field; processing the common header by either the RAPU or the BMPU, depending on the flow direction of the protocol data between a communication system and the other communication system; and thereafter, placing a message pointer at the first address of the data buffer for receiving next set of protocol data.

Description

Technical field [0001] The present invention is hereby referred to and incorporated in the prior submission of the Korean Industrial Property Office on September 4, 1998, entitled "Used in a wireless data communication processing device to interface a rate adaptation processing unit with a board messenger processing unit Method (METHOD FOR INTERFACING RATEADAPTATION PROCESSING UNIT AND BOARD MESSENGERPROCESSING UNIT IN A WIRELESS DATA COMMUNICATIONPROCESSING APPARATUS)", its formal designation serial number is 1998-36455, and all rights arising under 35U.S.Cξ119 are required. Background technique [0002] The invention relates to a method for interfacing a rate adaptation-processing unit (RAPU) with a board messenger-processing unit (BMPU) in a wireless data communication processing device. More particularly, it relates to a method for reducing the CPU (Central Processing Unit) load to be processed and minimizing the use of invalid storage of the communication protocol. [0003] ...
