METHOD AND SYSTEM TO MANAGE REAL-TIME AND NON-REAL-TIME DATA TRANSMISSION OVER A SHARED LINK WITH AN IMD
First Claim
1. A method in a medical telemetry system for communication between an implantable medical device (IMD) and an external device (ExD), said method comprising:
- collecting real-time (RT) data and non-real-time (NRT) data;
segmenting the RT data into RT packets and the NRT data into NRT packets;
loading the RT and NRT packets into a shared transmit buffer in the IMD in accordance with RT and NRT bandwidth allocations;
transmitting the RT and NRT packets from the IMD to the ExD in an order loaded in the transmit buffer; and
adjusting at least one of the bandwidth allocation and packet size based on a quality of service (QoS) characteristic.

Abstract
A medical telemetry system and method are provided for communication between an implantable medical device (IMD) and an external device (ExD). The method and system collects real-time (RT) data and non-real-time (NRT) data. The method and system segment the RT data into RT packets and the NRT data into NRT packets and load the RT and NRT packets into a shared transmit buffer in the IMD in accordance with RT and NRT bandwidth allocations and/or packet size. The method and system transmit the RT and NRT packets from the IMD to the ExD in an order loaded in the transmit buffer and adjust at least one of the RT and NRT bandwidth allocations and/or packet size based on a quality of service (QoS) characteristic.

13. An implantable medical device (IMD), comprising:
-
a transmitter/receiver for communication with an external device (ExD); inputs configured to collect real-time (RT) data; a controller configured to obtain non-real-time (NRT) data; the controller configured to segment the RT data into RT packets and the NRT data into NRT packets and load the RT and NRT packets into a shared transmit buffer in accordance with bandwidth allocation and packet size; a transmitter configured to transmit the RT and NRT packets from the IMD to the ExD in an order loaded in the transmit buffer; and wherein the controller is configured to adjust at least one of the bandwidth allocation and packet size based on a quality of service (QoS) characteristic. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
