Abstract

The invention discloses a WBAN information interaction method, device and system, wherein the method includes: Hub sends a beacon frame to a node and receives information sent by a node according to a preset superframe structure; wherein, the superframe structure Including three stages, the first stage includes the first beacon period, the first time slot period and the second time slot period, the first time slot period and the second time slot period are respectively used for nodes to send emergency services and ordinary services ; The second stage includes a second beacon period and a third time slot period, and the third time slot period is used for node supplementary transmission services; the third stage includes a fourth time slot period, and the fourth time slot period is used for A node sends a sleep request and / or an access request. Through the present invention, the problems existing in the signaling transmission structure of the WBAN in the related art are solved, the probability of transmission failure is greatly reduced, the time slot is utilized to a greater extent, and the priority transmission of emergency services is guaranteed as much as possible, while reducing node and network energy consumption.

Description

technical field

[0001] The present invention relates to the communication field, in particular, to a WBAN information exchange method, device and system. Background technique

[0002] Wireless body area network (WBAN for short) is a branch of wireless communication, which consists of sensors and personal terminals distributed on the surface or body of the human body. Through WBAN, the human body can communicate with external electronic devices such as mobile phones, and then can borrow other networks such as WIFI, 3G, etc., and finally send the information of the human body to the destination, such as a hospital. Wireless body area network can be applied in many fields, such as entertainment, sports, military field, etc., but the biggest driving force for its rise is the application in the medical field. With the improvement of people's living standards and higher pursuit of health, The application of WBAN in the medical field will be widely developed.
