Problems solved by technology

However, when multiple RLP data sets are received, any loss caused by bit errors in layers below the RLP layer 120 results in the data in the application layer 110 not being restored to its original size

Embodiment Construction

[0021] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The present invention is not limited to the following examples, and many modifications are possible within the spirit and scope of the invention. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

[0022] figure 2 It is a block diagram of the wireless data sending device of the present invention.

[0023] see figure 2 , the data encoding and decoding unit 210 encodes the application data by using an application program such as the H.323 encoding and decoding standard. The RLP format processing unit 220 compares the length of the encoded application data with the payload length of the format supported by the RLP layer. When the coded application data length is longer than the RLP format payload length, the RLP format processing unit 220 divides the application data and l...

Abstract

A method for transmitting and / or receiving wireless data is provided. The method includes the steps of (a) when the length of a collection of data in an application layer is longer than the length of the payload of a protocol which the lower layer supports, dividing the collection of data into a plurality of protocol units, and transmitting the protocol units of data after adding at least one of the length information and location information of the data divided into the protocol units; and (b) determining whether or not a loss of data occurred, by referring to the information on the length and location of data divided into the protocol units in the step (a), and inserting blank data into the part corresponding to the lost data to re-form the entire collection of data.

Description

technical field [0001] The present invention relates to a wireless data transmission and reception device and method, and more particularly to a wireless data transmission and reception device for processing divided protocol data, and a wireless data transmission and reception method. Background technique [0002] Usually, the wireless sending device and receiving device pair adopt figure 1 The layering shown in the block diagram. Including codec-related standards like H.234M, H.234 and T.120. The physical layer performs channel coding, pseudo-noise spreading, and modulation, and includes a section for over-the-air splicing. [0003] The Radio Link Protocol (hereinafter referred to as 'RLP') layer 120 includes a signaling unit (not shown), and converts a payload in the application layer 110 received through a wireless route into an input format of the physical layer 140 . [0004] The RLP layer 120 includes a plurality of RLPs, each corresponding to one of n application d...
