Problems solved by technology

In this case, in order to identify whether the cell supports the MTC device with enhanced coverage, the existing method is to make a MTC device with enhanced coverage first obtain the synchronization signal and Master Information Block (MasterInformationBlock, referred to as MIB), and then try to obtain the public SIB data related to coverage enhancement according to the MIB information. If the SIB data cannot be obtained within the determined time period, the coverage enhancement MTC device believes that the cell does not support coverage enhancement. MTC equipment; because the UE must try to receive public SIB data related to coverage enhancement for a long time, which may not exist, the above method leads to excessive unnecessary power consumption of the coverage enhancement MTC equipment
[0006] In the related art, no effective solution has been proposed for the problem of unnecessary power consumption of coverage-enhanced MTC equipment

Abstract

The present invention discloses a function indication method, device and system, wherein the function indication method comprises the steps of sending an instruction carried in a channel or a signal to a UE, wherein the UE needs to receive the channel or the signal when accessing a network initially and before receiving the physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH) data, the instruction is used to indicate whether the network support a preset function, and the PDSCH data comprises the PDSCH data of a system parameter of a broadcast carrying the UE and the PDSCH data carrying an unicast service. According to the present invention, the problem of covering and enhancing the unnecessary power loss of a machine type communication (MTC) UE is solved, thereby avoiding the excessive power loss of the MTC UE.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system for function indication. Background technique [0002] Machine Type Communication (MTC for short) or Machine to Machine (M2M for short) User Equipment (UE for short) is the main application form of the Internet of Things at the present stage. Low power consumption / low cost is an important guarantee for its large-scale application. Currently, M2M devices deployed in the market are mainly based on the Global System of Mobile communication (GSM for short) system. In recent years, due to the higher spectral efficiency of the Long Term Evolution (LTE) system, and more and more mobile operators have identified LTE as the evolution direction of the future broadband wireless communication system, the M2M multi-type data services based on LTE It will also be more attractive. [0003] The cost of user equipment (including MTCUE) mainly comes from two parts:...
