PDCP Data Compression for MTC Signaling Overhead

The patent segments the PDCP PDU by separating the packet data from the header information. The packet data is compressed and transmitted separately, while the header contains essential control information. This segmentation allows the network to efficiently handle multiple MTC UEs by reducing the overall signaling overhead while maintaining the ability to address and manage individual devices.

The patent extracts and transmits only the necessary packet data in the PDCP PDU, separating it from redundant information. By taking out only the essential data elements and compressing them, the system reduces traffic overhead while still supporting a large number of MTC UEs, thus resolving the contradiction between network capacity and overhead.

The patent applies compression algorithms at the data transmission stage before the data is sent over the network. By performing the compression action in advance, the system reduces the overhead of signaling and traffic. The decompression is then performed at the receiving end using standardized algorithms, which balances the processing complexity while achieving overhead reduction.

The patent changes the parameter of data representation by applying compression algorithms that transform the original data into a more compact form. This parameter change reduces the amount of data that needs to be transmitted and processed, thereby reducing overhead while managing processing complexity through efficient compression techniques.
