Implantable medical device and method for managing advertising and scanning schedules
First Claim
1. A device, comprising:
- memory to store a base scanning schedule that defines a pattern for scanning windows over a scanning state;
a radio frequency (RF) circuit configured to communicate with an implantable medical device (IMD), the RE circuit configured to enter the scanning state to scan for advertisement notices in accordance with the base scanning schedule;
memory to store a scan reset pattern for restarting the scanning state;
a processor configured to direct the RF circuit to automatically restart the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule, the base scanning schedule, scan reset pattern and the pseudo-scanning schedule being asynchronous with respect to advertising operations by the IMD; and
the processor configured to establish a communication session with the IMD.

Abstract
A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.

11. A device, comprising:
-
memory to store a base scanning schedule that defines a pattern for scanning windows over a scanning state and to store a scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule; a radio frequency (RF) circuit configured to communicate with an implantable medical device (IMD), the RF circuit configured to enter the scanning state to scan for advertisement notices in accordance with the base scanning schedule; one or more processors configured to execute an IMD application to; determine whether the IMO application is running in a foreground state or a background state; manage the scanning window in accordance with the pseudo-scanning schedule or the base scanning schedule based on the determine operation, the base scanning schedule and the pseudo-scanning schedule being asynchronous with respect to advertising operations by the IMD; and establish a communication session with the IMD. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
