Abstract

A system and method for providing wireless communications between a medical controller hub and an implant node are disclosed. The hub transmits signals to facilitate communication connections with the node. The signals include connection invitation polls with identification parameters. A node monitors the hub'"'"'s transmissions for the connection invitation polls. When a poll is detected, the node compares the identification parameters to a list of preferred identification values. If the received identification parameter is on the preferred list, and the node and hub are not already connected, then the node responds to the connection invitation poll. If the received identification parameter is not on the preferred list, then the node continues to monitor hub transmissions for other connection invitation polls that include identification parameters that are on the preferred list.

Claims

1. A method, comprising:

receiving, by a network node from a hub, a poll message including a hub identification representing a service available near the hub;

determining, by the network node, a condition associated with a user of the network node;

responding, by the network node, to the poll message if the condition corresponds to the service represented by the hub identification; and

ignoring, by the network node, the poll message if the condition does not corresponds to the service represented by the hub identification.

2. The method of claim 1, wherein, the hub identification includes an identifier selected from a group consisting of a emergency hub identifier, a medical facility identifier, or a home hub identifier.

3. The method of claim 1, further comprising:

monitoring, by the network node, a second poll message from a second hub, if the condition does not corresponds to the service represented by the hub identification of the hub.

4. The method of claim 1, further comprising:

extracting information from a body area network identification field in the poll message, wherein the information comprises the hub identification.

5. The method of claim 1, further comprising:

extracting information from a sender identification field and from a body area network field in the poll message, wherein the information comprises the hub identification.

6. The method of claim 1, wherein the condition includes a medical condition selected from a group consisting of a medical emergency condition and a medical non-emergency condition.
