Detection and self-healing of a mobile communication device network access failure
View Patent ↗A method of responding to a network connection failure in a mobile communication device. The method comprises receiving an error message indicating a data connection failure, activating an application configured to attempt to access the network using a first identifier on the mobile communication device in response to receiving the error message, sending an SMS message from the mobile communication device over an SMS control channel in an attempt to access the network, receiving information indicating a failure to access the network through the SMS control channel, determining that the failure to access the network is based on the first identifier, performing a limited reset of the mobile communication device to replace the first identifier with a factory default identifier, confirming through use of the factory default identifier that the first identifier is inactive, and establishing the factory default identifier such that the mobile communication device is configured for activation.
1. A method of responding to a network connection failure in a mobile communication device, the method comprising:
receiving, by a mobile communication device, an error message indicating a data connection failure;
activating an application on the mobile communication device in response to receiving the error message, wherein the application is configured to attempt to access the network using a first identifier;
sending, by the application, an SMS message from the mobile communication device over an SMS control channel in an attempt to access the network;
receiving, by the mobile communication device, information indicating a failure to access the network through the SMS control channel;
determining, by the mobile communication device, that the failure to access the network is based on the first identifier;
performing a limited reset of the mobile communication device, wherein the first identifier on the mobile communication device is replaced with a factory default identifier, and wherein performing the limited reset comprises performing a DSP modem reset configured to allow the application execution to continue after the first identifier has been replaced by the factory default identifier;
confirming, through use of the factory default identifier, that the first identifier is inactive; and
establishing the factory default identifier such that the mobile communication device is configured for activation.
2. The method of claim 1 , wherein the factory default identifier is a first time identifier applied by a manufacturer.
3. The method of claim 1 , wherein the application is configured to attempt to access the network by sending the SMS message.
4. The method of claim 1 , wherein activating the application occurs in response to at least one of receipt of the error message or receipt of an input from a user.
5. The method of claim 1 , wherein establishing the factory default identifier comprises establishing a factory default setting configured to limit the mobile communication device from attempting to access the network in the factory default state without first receiving activation instructions from an authorized activation application.
6. The method of claim 1 , further comprising:
storing the first identifier in a persistent data store in response to determining that the failure to access the network is based on the first identifier.
7. The method of claim 6 , further comprising:
deleting the stored first identifier from the persistent data store in response to confirming that the first identifier is inactive.
8. The method of claim 1 , wherein establishing the factory default identifier such that the mobile communication device is configured for activation comprises establishing the mobile communication device as a cold device.
9. A method of responding to a network connection failure in a mobile communication device, the method comprising:
receiving, by a mobile communication device, an error message indicating a network connection failure;
activating an application on the mobile communication device, wherein the application is configured to attempt to access the network;
determining, at the mobile communication device, that a first identifier failed to access the network based on the first identifier;
storing the first identifier in a persistent data store;
performing a limited reset, wherein the first identifier on the mobile communication device is replaced with a factory default identifier, and wherein performing the limited reset comprises performing a DSP modem reset configured to allow the application execution to continue after the user identifier has been replaced with the factory default identifier;
attempting to access the network with the factory default identifier;
obtaining access to the network using the factory default identifier;
verifying that the first identifier is active based on obtaining access to the network; and
re-establishing the first identifier from the persistent data store.
10. The method of claim 9 , wherein the error message indicates a data connection failure.
11. The method of claim 9 , further comprising:
attempting, by the application, to access the network via SMS over a voice channel.
12. The method of claim 9 , further comprising:
preventing the application from re-executing once the first identifier has been re-established.
13. The method of claim 9 , wherein the first identifier is a user MEID.
