Data communication method and data communication service node

Abstract

The invention provides a data communication method and a data communication service node. The data communication method comprises the following steps of obtaining a message and a subscription data which are used for data communication, wherein the message and / or the subscription data which are / is used for the data communication comprise(s) data communication indication information; and determining a compression strategy of the data communication according to the data communication indication information. By using the data communication method and the data communication service node provided by the invention, when the data communication is carried out, whether the data communication belongs to small data communication is distinguished; if the small data communication exists, data compression and / or header compression are / is not performed, so that processing resources consumed by the data communication can be reduced, and the real-time performance of the data communication can be improved.

Description

technical field [0001] The embodiments of the present invention relate to mobile communication technologies, and in particular to a data communication method and a data communication service node. Background technique [0002] In the third generation partnership project (Third Generation Partnership Project, referred to as 3GPP) communication system, the compression function is performed during data communication, and the service data unit (Service Data Unit, referred to as SDU) can be transmitted as little as possible, thereby optimizing the wireless path capacity usage of. [0003] At present, in various communication occasions such as the Internet of Things, Machine Type Communication (MTC for short), and Internet applications on smartphones, there are a large number of small data communications, among which, user equipment (User Equipment, UE for short) only sends and receives small data. A small amount of data may include content data and / or signaling data. For exampl...

Problems solved by technology

[0004] When performing the above small data communication, if the compression function is performed, it is necessary to identify the data type, negotiate the compression algorithm and related parameters with the UE, perform compression and decompression calculations, and store relevant data generated during the compression process, which consumes a lot of processing resources. And the data compression process introduces a delay

Due to the small amount of communication data, the number of transmission bits saved by the compression process is very small, but it consumes a lot of processing resources

Moreover, if the small data communication transmits signaling data, such as signaling or control messages, the real-time requirements are high, and the delay introduced by the compression function reduces the real-time performance of the communication
