Automating dial attempts to a telematics or cellular device
View Patent ↗A system and method of managing communications with a vehicle telematics unit includes determining that a data transmission to a vehicle telematics unit over a wireless carrier system has failed; automatically performing a network registration check with the wireless carrier system to determine the registration status of the vehicle telematics unit based on the data transmission failure; and deciding whether to re-transmit the data to the vehicle based on the results of the network registration check.
1. A method of managing communications with a vehicle telematics unit, comprising the steps of:
(a) determining that a data transmission to a vehicle telematics unit over a wireless carrier system has failed;
(b) automatically performing a network registration check with the wireless carrier system to determine the registration status of the vehicle telematics unit based on the data transmission failure; and
(c) deciding whether to re-transmit the data to the vehicle based on the results of the network registration check.
2. The method of claim 1 , wherein determining that the data transmission has failed further comprises the step of determining that the amount of time the vehicle telematics unit takes to respond to a call center is greater than a predetermined threshold.
3. The method of claim 1 , further comprising the step of determining if a network registration check for the vehicle telematics unit is currently pending.
4. The method of claim 1 , wherein performing the network registration check further comprises the step of querying a data cache maintained by the wireless carrier system.
5. The method of claim 1 , wherein the network registration check is performed by sending data to a mobile number management system (MNMS).
6. The method of claim 1 , further comprising the step of deciding whether to retransmit data to the vehicle telematics unit based on a history of network registration checks that are stored in a data cache.
7. The method of claim 1 , wherein the results of the network registration check are that the vehicle telematics unit is online, is offline, or is recently offline.
8. The method of claim 1 , wherein the data is re-transmitted to the vehicle based on a long-term retry strategy that includes two or more short-term retry strategies.
9. A method of managing communications with a vehicle telematics unit, comprising the steps of:
(a) determining that a vehicle telematics unit cannot receive a data transmission from a central facility;
(b) performing a network registration check for the vehicle telematics unit by querying a data cache containing cellular network registrations for vehicle telematics units; and
(c) if a network registration check is not pending, then implementing a long-term retry strategy to contact the vehicle telematics unit.
10. The method of claim 9 , wherein determining that the vehicle telematics unit cannot receive a data transmission further comprises the step of determining that the amount of time the vehicle telematics unit takes to respond to a call center is greater than a predetermined threshold.
11. The method of claim 9 , wherein performing the network registration check further comprises the step of querying a data cache maintained by the wireless carrier system.
12. The method of claim 9 , wherein performing the network registration check includes sending data to a mobile number management system (MNMS).
13. The method of claim 9 , wherein the content of the long-term retry strategy to contact the vehicle telematics unit is based on a history of network registration checks that are stored in a data cache.
14. The method of claim 9 , wherein the results of the network registration check are that the vehicle telematics unit is online, is offline, or is recently offline.
15. The method of claim 9 , wherein the long-term retry strategy includes two or more short-term retry strategies.
16. The method of claim 9 , wherein the content of the long-term retry strategy is determined based on recursive analysis of previously-implemented long-term retry strategies.
17. A method of managing communications with a vehicle telematics unit, comprising the steps of:
(a) transmitting data from a central facility to a vehicle over a wireless carrier system;
(b) determining that the vehicle is unable to receive the data transmission;
(c) performing a network registration check based on the determination that the vehicle is unable to receive the data transmission;
(d) identifying a long-term retry strategy for wirelessly contacting the vehicle that includes one or more individual short-term retry strategies; and
(e) contacting the vehicle using the identified long-term retry strategy as well as one or more individual short-term retry strategies.
18. The method of claim 17 , wherein the content of the long-term retry strategy to contact the vehicle is based on a history of network registration checks that are stored in a data cache.
19. The method of claim 17 , wherein the results of the network registration check are that the vehicle telematics unit is online, is offline, or is recently offline.
20. The method of claim 17 , wherein the long-term retry strategy is identified based on recursive analysis of previously-implemented long-term retry strategies.
