Abstract
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.
Claims15
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.
A method of assigning a channel according to mobility of a medical body area network (MBAN) device in an MBAN network, the method comprising:
- transmitting, by the MBAN device to an MBAN master, an association request signal including information about the mobility of the MBAN device;
- receiving, by the MBAN device from the MBAN master, an association response signal in response to the transmitted association request signal;
- receiving, by the MBAN device from the MBAN master, channel assignment information according to the information about the mobility included in the transmitted 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 received from the MBAN master 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 received from the MBAN master periodically through a beacon frame.

- a memory device;
- and
- a processor operatively connected to the memory device and configured to:
- receive, from the MBAN device, an association request signal including information about the mobility of the MBAN device;
- transmit, to the MBAN device, an association response signal in response to the received association request signal;
- and
- transmit, 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.
