Method and apparatus for transreceiving data in medical body area network
First Claim
1. A method of transmitting and receiving data by a terminal with a base station in a medical body area network (MBAN), the method comprising:
- receiving available channel list information from the base station via a channel of a first frequency band, the available channel list information indicating at least one available channel of a second frequency band;
performing channel switching from the channel of the first frequency band to one of the at least one available channel of the second frequency band, based on the available channel list information; and
communicating data with the base station via the channel-switched available channel,wherein receiving the available channel list information includes;
receiving a beacon frame from the base station via the channel of the first frequency band,transmitting to the base station an electronic key request message for requesting available channel information of the second frequency band, andreceiving from the base station an electronic key response message in response to the electronic key request message,wherein the available channel list information is contained in the electronic key response message, andwherein the electronic key response message comprises personal area network identifier (PAN ID) information representing a wireless personal area network (WPAN) using a specific channel of the second frequency band, and transmit power limit information representing maximum transmission power in the specific channel of the second frequency band.

Abstract
The present invention relates to a method for a terminal transreceiving data with a base station in a medical body area network (MBAN) comprising the following steps: receiving from the base station information on an available channel list, which shows at least one available channel from a second frequency band, through a first frequency band; channel switching from one channel from the first frequency band to one of the available channels from the second frequency band based on the information on the available channel list; and transreceiving data with the base station through the available channel to which the channel is switched.

10. A terminal for transmitting and receiving data with a base station in a medical body area network (MBAN), the terminal comprising:
-
a radio frequency unit for transmitting and receiving a radio signal; and a controller connected to the radio frequency unit, wherein the controller controls the radio frequency unit to receive available channel list information via a channel of a first frequency band, the available channel list information indicating at least one available channel of a second frequency band, performs channel switching from the channel of the first frequency band to one of the at least one available channel of the second frequency band, based on the available channel list information, and controls the radio frequency unit to communicate data with the base station via the channel-switched available channel, wherein receiving the available channel list information includes; receiving a beacon frame from the base station via the channel of the first frequency band, transmitting to the base station an electronic key request message for requesting available channel information of the second frequency band, and receiving from the base station an electronic key response message in response to the electronic key request message, wherein the available channel list information is contained in the electronic key response message, and wherein the electronic key response message comprises personal area network identifier (PAN ID) information representing a wireless personal area network (WPAN) using a specific channel of the second frequency band, and transmit power limit information representing maximum transmission power in the specific channel of the second frequency band. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
