Equipment dormancy method based on CSM mechanism DRX

Abstract

The invention discloses an equipment dormancy method based on a CSM mechanism DRX. The method comprises the following steps that under an RRC_CONNCTED ACTIVE state, a MTCD transmits a first data packet to a base station, then decodes and reads information N of a data packet number which needs to be continuously transmitted; a deactivation timer and a packet counter whose threshold is the N are started, downlink channel monitoring and data uploading are continuously performed, and after a dormancy condition is satisfied, a Short DRX state is entered into; under the Short DRX state, and in an On Duration period, data monitoring is performed, and if a DRX short period timer is overtime and does not monitor the data, the MTCD enters into a Long DRX state; under the Long DRX state, and in the On Duration period, the data monitoring is performed, and if a DRX long period timer is overtime and does not monitor the data, the MTCD enters into an IDLE DRX state; and under the IDLE DRX state, the MTCD is periodically awakened to monitor downlink transmission of a network till that the MTCD is paged, and then the MTCD returns and enters into the RRC_CONNCTED ACTIVE state. The invention provides the equipment dormancy method based on the CSM mechanism DRX so that the equipment can carry out high-efficiency operation when entering into a low power consumption dormancy state.

Description

technical field [0001] The present invention relates to a machine-type communication device in the field of 5G communication, in particular to a device dormancy method based on a CSM mechanism DRX. Background technique [0002] In the 5G era, Machine Type Communication (MTC, Machine Type Communication) is getting more and more attention, and is even regarded as the most critical application in the 5G mobile communication network; for the current LTE mobile communication network, 3GPP proposes discontinuous reception ( The DRX (Discontinuous Reception) mechanism enables traditional user equipment (UE) to only send and receive data in a specific time slot, and turn off the wireless module in the remaining time slots, thereby saving power consumption of the user equipment. [0003] The standard DRX mechanism proposed by 3GPP is as follows: figure 1 As shown, in the RRC_IDLE state, the user equipment (UE) is registered in the mobility management entity (MME, Mobility Management...

AI Technical Summary

Problems solved by technology

[0003] The standard DRX mechanism proposed by 3GPP is as follows: figure 1 As shown, in the RRC_IDLE state, the user equipment (UE) is registered in the mobility management entity (MME, Mobility Management Entity), but there is no active session

[0011] However, since the original intention of the design of the LTE network is mainly for human-to-human communication (H2H, Human to Human), the existing protocols and mechanisms are not very effective, and the MTC traffic characteristics are not the same as the traditional H2H traffic size and the frequency of data generation. The same, so the current DRX mechanism cannot fully meet the requirements of machine type communication (MTC), and cannot fully adapt to the MTC service requirements in the future 5G network; in this type of mobile communication network, in order to meet the MTC service requirements, some improvements need to be made ; and the power consumption of machine type devices (MTCD, Machine Type Communication Device) represented by sensors is a key issue in MTC communication. Therefore, we focus on how to reduce the power consumption of MTCD by improving the DRX mechanism
