Method and apparatus for home network access by a trusted monitoring agent
View Patent ↗A manner of extending a home network to a remote TMA service. A TMA in the TMA service acquires and stores a UID (unique identifier) and a MS-UID (monitoring service UID), than registers with an SG (signaling gateway) and is then redirected to an MA-SG (monitoring application SG). The MA-SG may be dedicated to the TMA service or may host communications for more than one service. When an HA that subscribes to the monitoring service registers, it is also redirected to the MA-SG, and a secure tunnel is established between the TMA and the HA and maintained by heartbeat messages. The secure tunnel may be redirected to an MA-PS (monitoring application proxy server) depending on the bandwidth consumed in the monitoring process and traffic conditions.
1. A method of providing home network access across a NAT (network address translation) boundary for a remote monitoring service associated with a TMA (trusted monitoring agent), the method comprising:
registering a subscribing HA (home agent) of a home network with a SG (signaling gateway) to establish a communication session;
acquiring an UID (unique identifier) for the TMA;
registering the TMA with an MA-SG (monitoring application signaling gateway);
initiating a heartbeat between the TMA and the MA-SG;
receiving an indication that the subscribing HA subscribes to the remote monitoring service associated with the TMA;
directing the HA to fork the communication session with the SG into a monitoring fork;
redirecting the monitoring fork of the communication session with the SG in the direction of the MA-SG;
establishing a monitoring fork tunnel of the monitoring fork that connects the TMA and the HA through the MA-SG; and
monitoring via the monitoring fork tunnel at least one device of the home network associated with the HA.
2. The method of claim 1 , further comprising acquiring a MS-UID (monitoring service UID) in the TMA.
3. The method of claim 2 , further comprising encrypting and storing the UID and the MS-UID by the TMA.
4. The method of claim 2 , further comprising registering the MS-UID with an OSS/BSS of a communications network.
5. The method of claim 1 , wherein registering the TMA with an MA-SG comprises registering the TMA with an SG of the communications network.
6. The method of claim 5 , wherein registration with the SG comprises an authentication procedure.
7. The method of claim 1 , wherein the MA-SG is a part of the same monitoring service as the TMA.
8. The method of claim 1 , wherein the MA-SG is a hosting MA-SG.
9. The method of claim 6 , wherein the hosting MA-SG is part of a monitoring service different than the monitoring service associated with the TMA.
10. The method of claim 6 , further comprising receiving in the TMA an allocation of ports associated with the service.
11. The method of claim 1 , wherein the at least one device of the home network is a medical device controller.
12. The method of claim 1 , wherein the at least one device of the home network is a home security system controller.
13. The method of claim 1 , further comprising initiating a heartbeat between the TMA and the HA.
14. The method of claim 13 , further comprising monitoring messages between the TMA and the HA and suspending a heartbeat when recent message traffic is sufficient to maintain an opening in the NAT boundary or boundaries, if any, associated with the remote monitoring service and the home network.
15. The method of claim 1 , further comprising receiving an alarm from the home network and initiating an emergency call from a telephone in the home network.
