Paging-based low-power consumption communication method and paging-based low-power consumption communication network

Abstract

The invention relates to a paging-based low-power consumption communication method. Thus, a transmitting side and a receiving side for wireless communication are dormant in a condition in which no data need to be transmitted and received, and when data need to be transmitted, the transmitting side exits dormancy and transmits a series of paging frames. Through transmitting and receiving of the paging frames, the transmitting side and the receiving side build clock synchronization, select an appointed time slot for wakeup and perform data exchange. The communication method of the invention is used for supporting large-scale networking for low-flow wireless communication networks. The invention also relates to a paging-based low-power consumption communication network, which comprises a base station, a relay, and a terminal. Uplink or downlink communication can be carried out based on the communication method, power saving effects for each device are realized, and the communication stability can be ensured.

Description

technical field [0001] The invention relates to the field of wireless communication, more specifically, to a paging-based low-power communication method and a paging-based low-power communication network. Background technique [0002] The Internet of Things, or sensor network, usually requires one end of the communication link, such as the base station equipment, to remain in the receiving or listening state, and by maintaining relatively high energy consumption, it is ensured that the base station can correctly receive the messages sent by the sensor. [0003] In order to achieve the purpose of saving power, in the prior art, the IoT terminal establishes and maintains clock synchronization with the access point (AP) or repeater, and assigns a fixed time slot to each terminal. The access point (AP) or repeater Repeaters can operate in an energy-intensive receive or listen state during these allocated time slots. Hibernate at other times to save energy or extend battery life...

AI Technical Summary

Problems solved by technology

[0004] However, in practical applications, the data transmission requirements of IoT terminals are triggered by events, which is difficult to predict in advance

[0005] If the access point (AP) or repeater reserves time slots for these terminals, it will lead to waste of energy consumption

When the number of terminals is large, these reserved time slots will cause the access point (AP) or repeater to have no sleep time at all

[0006] However, if the repeater does not reserve time slots for these downstream nodes, when these nodes are triggered by specific events and generate and send messages to the repeater for forwarding, the repeater may be in a dormant state and cannot wake up in time Receive the data uploaded by the terminal, resulting in a significant drop in the communication stability of the entire network
