First Claim
Patent Images
1. A system for maintaining a medical body area network (MBAN), said system comprising:
- at least one controller configured to;
communicate with devices of the MBAN over one or more channels of the MBAN, the one or more channels including a primary channel that includes a minimum allowed priority level, and each of the devices assigned to one of the one or more channels, wherein each of the devices includes a priority;
continuously monitor a duty cycle of each of the one or more channels; and
in response to the duty cycle of the primary channel meeting or exceeding a duty cycle limit, move a device of the devices to a secondary channel of the one or more channels based on the priority level of the device relative to the minimum allowed priority level;
wherein the at least one controller is further configured to communicate with the devices over each of the primary and secondary channels using a beacon-based superframe structure;
wherein periods of active transmission on the primary and secondary channels are non-overlapping;
wherein beacons of the primary channel include data regarding the superframe structure of the secondary channel.

Abstract
A system (52) and a method maintain a medical body area network (MBAN) (62). Devices (56, 58) of the MBAN (62) are communicated (152) with over one or more channels of the MBAN (62). The one or more channels include a primary channel, and each of the devices (56, 58) is assigned to one of the one or more channels. Further, a duty cycle of each of the one or more channels is continuously monitored (156). In response to the duty cycle of the primary channel meeting or exceeding a duty cycle limit, a device (56, 58) of the devices (56, 58) is moved (158) to a secondary channel.

7. A method for maintaining a medical body area network (MBAN), said method comprising:
-
communicating with devices of the MBAN over one or more channels of the MBAN, the one or more channels including a primary channel that includes a minimum allowed priority level and secondary channel, and each of the devices assigned to one of the one or more channels, wherein each of the devices includes a priority level; continuously monitoring a duty cycle of each of the one or more channels; and in response to the duty cycle of the primary channel meeting or exceeding a duty cycle limit, moving a device of the devices to a secondary channel based on the priority level of the device relative to the minimum allowed priority level; wherein the communicating with the devices over each of the primary and secondary channels uses a beacon-based superframe structure; wherein periods of active transmission on the primary and secondary channels are non-overlapping; wherein beacons of the primary channel include data regarding the superframe structure of the secondary channel. - View Dependent Claims (8, 9, 10, 11, 12)
