Abstract

The present invention relates to an energy consumption evaluation and optimization method of an extended discontinuous reception mechanism (eDRX). It belongs to the field of narrowband Internet of Things. The present invention includes the following steps: S1: when the terminal adopts the extended discontinuous reception mechanism (eDRX), establishes a Markov model with the terminal working state as a state variable; S2: when the terminal has data to transmit, it tries to randomly access the network; S3: When the random access of the terminal fails, the terminal needs to perform a backoff process, and the backoff value is determined by the number of re-access times and the initial backoff value; S4: When the backoff value increases linearly as mentioned above, the above energy evaluation model is used for verification. The invention can effectively and comprehensively evaluate the energy consumption of the terminal, effectively reduce the energy consumption of the terminal, improve the utilization rate of battery energy, and finally improve the life of the terminal.

Description

technical field

[0001] The invention belongs to the field of narrowband Internet of Things, and relates to an energy consumption evaluation and optimization method of an extended discontinuous acceptance mechanism (eDRX). Background technique

[0002] Narrowband Internet of Things (NB-IOT) aims to enhance indoor coverage, support a large number of low-throughput devices, low latency sensitivity, ultra-low-cost, low-power devices, and network architecture. In order to achieve its set target of low delay sensitivity and low power consumption, an extension to the power saving of the original DRX mechanism in LTE is adopted. The extended discontinuous reception mechanism (eDRX) has a longer paging cycle than the DRX mechanism. The eDRX mechanism stipulates that in each eDRX cycle, the terminal can receive downlink data only within the set paging time window, and the terminal is in a dormant state during the rest of the time and does not accept downlink data. In each eDRX cycle...
