Description

Internet of things terminal and power saving mode adjusting method thereof
Technical Field
The invention relates to the field of communication, in particular to an Internet of things terminal and a power saving mode adjusting method thereof.
Background
Among a plurality of communication technologies of the internet of things, a Low Power Wide Area Network (LPWAN) technology well meets the data transmission requirements of services with high requirements on Power consumption and coverage (such as intelligent meter reading) in the connection requirements of the internet of things by virtue of the outstanding advantages of Low Power consumption, Wide Area coverage and the like. Two cellular Internet of things technologies, namely NB-IoT (Narrow Band Internet of things) and eMTC (enhanced Machine-Type communication), which are formulated by organizations such as 3GPP, are typical representatives of LPWAN technologies, and compared with conventional cellular communication technologies (2G, 3G, 4G, and the like), special function optimization is provided for requirements of low Power consumption, for example, functions such as PSM (Power Saving Mode) and eDRX (Extended discontinuous reception) are all important to the Power Saving effect of an Internet of things terminal. In the PSM mode, the terminal still registers in the network, the network side still retains the terminal-related information, but the terminal no longer monitors the signaling and data of the network, so that the terminal can stay in the deep sleep for a longer time to achieve the purpose of saving power, which can be regarded as a deep sleep state. The eDRX further extends the sleep cycle of the terminal in the idle mode, and reduces unnecessary activation and reception monitoring of the receiving unit of the terminal, thereby saving energy consumption. The two functions can achieve the purpose of saving power of the terminal to different degrees, the former realizes more thorough power saving characteristic by partially sacrificing the real-time accessibility of the communication link, and the latter makes a compromise balance between power saving and the accessibility of the communication link.
Regarding the selection problem of two power saving modes of PSM and eDRX, according to the current 3GPP protocol, cellular network operators generally allocate a designated APN (Access Point Name) to terminals accessing the network according to the service characteristics of the terminals, and for terminals of the internet of things belonging to the same APN, the network side selects one or two combined power saving modes and corresponding parameters from the two modes of PSM and eDRX according to the characteristics (such as transmission cycle) of service data transmission, and configures the power saving modes and the corresponding parameters to the terminals through corresponding signaling. Once the parameters are set, the power saving mode of any internet of things terminal is determined, and the power saving mode cannot be modified under the current network protocol/operation flow in the operation process of the internet of things terminal. However, in practice, data transmission of many services is in different scenes or different time periods, and the characteristics of the services for data transmission are different; the power saving function and corresponding parameters of the prior art and the process cannot be dynamically adjusted according to the characteristics of the prior art and the process, so that the power saving efficiency of the current internet of things terminal is not unexpectedly high in certain application scenes.
