Abstract

The invention discloses a semi-static scheduling method. The semi-static scheduling method includes enabling a center node to distribute an independent scheduling period and an independent scheduling duration for each service of each terminal node when the terminal node of a wireless body area network is required to be scheduled, notifying the terminal nodes of scheduling information of the terminal nodes by the aid of connection configuration frames; interchanging data between the terminal nodes and the center node for each service according to the scheduling information and the scheduling period and the scheduling duration of the service. The scheduling periods and the scheduling durations of the corresponding services are carried in each resource configuration field in uplink distribution cells, downlink distribution cells and bidirectional distribution cells in the connection configuration frames. The semi-static scheduling method has the advantages that QoS (quality of service) requirements on the various services of the terminal nodes of the wireless body area networks can be met by the aid of the semi-static scheduling method, and wastage of scheduling resources can be effectively prevented.

Description

technical field [0001] The invention relates to a wireless body area network communication technology, in particular to a semi-static scheduling method of a wireless body area network. Background technique [0002] With the intensification of my country's urbanization process and population aging, senile diseases and chronic diseases are becoming more and more common. In addition to bringing heavy economic burdens to patients and society, they also seriously affect the quality of life of patients and family happiness. The emergence of Wireless Body Area Network (WBAN) provides a simple and low-cost means of short-distance communication for home health monitoring of geriatric and chronic diseases. Based on WBAN technology, by arranging corresponding sensing devices on the human body surface or in the body, it automatically collects vital sign parameters such as human ECG, EEG, EMG, body temperature, blood pressure, blood sugar, blood oxygen, etc., to support real-time, conven...
