Detection and self-healing of a mobile communication device network access failure

摘要

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performing a DSP modem reset configured to allow the application execution to continue after the first identifier has been replaced by the factory default identifier; confirming, through use of the factory default identifier, that the first identifier is inactive; and establishing the factory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.
