Method for implementing CIoT EPS (Cellular Internet of Things Evolved Packet System) hybrid optimization under condition of NB-IoT (Narrow Band-Internet of Things) system

Abstract

The present invention provides a method for implementing CIoT EPS (Cellular Internet of Things Evolved Packet System) hybrid optimization under the condition of an NB-IoT (Narrow Band-Internet of Things) system. According to the method, signaling control is adopted to complete the optimization mode configuration of bearers in a bearer setup process, wherein the bearer setup process includes a control plane CIoT EPS optimization bearer setup process and a user plane CIoT EPS optimization bearer setup process, wherein the two setup processes are independent of each other; terminals and a core network complete the setup of a plurality of bearers and the optimization mode attribute configuration of the bearers according to the different capabilities of the terminals, and the association of service data with CIoT EPS optimization bearers is realized through the TFTs (Traffic Flow Template) of the bearers, and therefore, a hybrid optimization mode can be formed. With the method adopted, problems such as control conflict, data loss, and service interruption caused by dynamic conversion between optimization modes can be solved; the association of the service data with the different CIoT EPS optimization mode bearers is realized simply and quickly with the processing complexity of the terminals and the network not increased, the complexity of rules between the terminals and applicationlayers can be reduced, and requirements for the application layers can be reduced.

Description

technical field [0001] The invention relates to a method for realizing hybrid optimization of CIoT EPS under the NB-IoT system. Background technique [0002] With the development of Internet of Things communication technology, the demand for Internet of Things services in all aspects of production and life continues to increase. At the same time, low-speed services have gradually become the main market development direction of the cellular Internet of Things in the future. The industry has unified this part of the market into LPWAN (Low Power Wide Area Network (Low Power Wide Area Internet of Things) market, in the face of LPWAN market demand, traditional mobile communication technology has been unable to meet more and more Internet of Things application business needs, as the third wave of information industry development, While various industries continue to explore and tap the maximum value of the concept of the Internet of Things, they also continue to provide support fr...
