Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In the embodiment of the present invention, an interaction mechanism of beacon offset information is established between BANs, and the beacon offset sequence selected by the BAN is added to the request and response messages for activating superframe interleaving exchanged between adjacent BANs information, to avoid the phenomenon that the same beacon offset sequence is selected again due to simultaneous adjustment by both parties, or the phenomenon that both parties do not adjust and maintain beacon offset conflicts, so that adjacent BANs can exchange information accurately and effectively. Consistently complete the staggered transmission of beacon signals. In the scenario where the activated superframes of adjacent BANs overla...

Abstract

Disclosed is a method for reducing wireless-body-area-network (WBAN) system interferences. The method includes: a second multi-port repeater hub2 of a second adjacent body area network BAN2 sends an activation superframe interlacing request to a first multi-port repeater hub1 of a first adjacent body area network BAN1, wherein the activation superframe request includes a beacon offset sequence of the BAN2; and the hub1 feeds back an activation superframe interlacing response to the hub2 after performing judgment according to the beacon offset sequence of the BAN2, wherein the fed back activation superframe interlacing response includes a beacon offset sequence of the BAN1. After the method for reducing the WBAN system interferences is applied, generation of strong interferences between beacons is prevented so that transmission performance of BAN edge nodes and overall performance of a system are effectively ensured.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to a method for reducing interference in a wireless body area network (WBAN) system. Background technique [0002] WBAN is a communication network between devices close to the human body or implanted in the human body. It can provide a series of applications, including medical support, health monitoring and consumer electronics, etc., providing users with great convenience and comfort. Gradually occupy an important position in future communication. [0003] As a short-distance communication, the advantage of WBAN is low transmission power level: on the one hand, low transmission power level can directly bring low energy consumption and long-term use of batteries; on the other hand. Low transmit power can avoid or mitigate interference from other wireless systems. It has been determined that the WBAN will use the IEEE 802.15.6 standard. [0004] Although ...
