Method and device for selecting a channel according to a device's mobility

摘要

The present invention relates to a method of selecting a channel, and more particularly, to a method of selecting a channel according to a Medical Wireless Body Area Network (MBAN) device's mobility, and of using same. The method includes: receiving, by a Medical Body Area Network (MBAN) master, a connection request signal including information on mobility from an MBAN device; transmitting, by the MBAN master, a connection response signal to the MBAN device in response to the received connection request signal; and allocating a channel for the MBAN device according to the information on mobility in the received connection request signal.

1. A method of assigning a channel according to mobility of a medical body area network (MBAN) device in an MBAN network, the method comprising:
receiving, by an MBAN master from the MBAN device, an association request signal including information about the mobility of the MBAN device; transmitting, by the MBAN master to the MBAN device, an association response signal in response to the received association request signal; and transmitting, by the MBAN master to the MBAN device, channel assignment information according to the information about the mobility included in the received association request signal, wherein, when the information about the mobility of the MBAN device indicates that the MBAN device is a fixed device, the channel assignment information is transmitted to the MBAN device once through a non-beacon frame, and wherein, when the information about the mobility of the MBAN device indicates that the MBAN device is a mobile device, the channel assignment information is transmitted to the MBAN device periodically through a beacon frame.
