DATA TRANSMISSION METHOD IN ONE MACHINE TO MACHINE SYSTEM AND COMMON SERVICES ENTITY

摘要

Provided in an embodiment of the present invention are a data transmission method in a one machine to machine (oneM2M) system and a common services entity (CSE), the method comprising: acquiring a quality of service (QoS) variable parameter of an application layer, the QoS variable parameter of the application layer being used to represent a data transmission quality requirement of an application; mapping the QoS variable parameter of the application layer to a target QoS variable parameter capable of being recognized by a bottom-level network; and transmitting the target QoS variable parameter to a network services entity (NSE), such that the NSE transmits data according to the target QoS variable parameter. The data transmission method provided in the embodiment of the present invention can satisfy network QoS requirements of applications in different application scenarios in a oneM2M system.
