IMPLANT ACCESS IN THE MEDICAL IMPLANT COMMUNICATIONS SERVICE BAND

摘要

A system and method for providing communications between a hub (medical controller) and a node (an implant) are disclosed. The hub selects an operating channel within a channel group in accordance with applicable regulations, and transmits signals to facilitate communications with nodes. A node sequentially tunes to individual channels within the group, monitoring each channel for a hub transmission during a monitoring period. If a hub transmission is detected, the node stays on the current channel. Otherwise, the node tunes to a next channel in the channel group. The hub transmission may be directed to unconnected nodes, to a single connected node, or to a group of connected nodes. The node transmits a first frame to the hub at a designated transmission time and receives a response. The node reports an emergency by sequentially transmitting emergency frames on each of the channels until receiving an acknowledgment from the hub.

1. A method of identifying a channel to report an event, comprising:
sequentially tuning a transceiver to individual channels within a channel group; transmitting a first event notification frame on the individual channel; monitoring the individual channel during a monitoring period for a hub transmission in acknowledgment of the event notification frame; tuning the transceiver to a next individual channel in the channel group if no hub transmission is detected during the monitoring period; if a hub transmission is detected on a current channel within the channel group, stopping the sequential tuning the transceiver to a next individual channel; and in view of the hub acknowledgment, transmitting one or more event data frames on the current channel.
