Claim of US Patent No. 9,241,359

1. A method for delaying authentication of a mobile device after a radio link failure, the method comprising:
at a current control component, receiving a message indicating that the radio link failure occurred at a previous control
component, the message including an identity of the previous control component to which the mobile device was attached prior
to the radio link failure;

in response to receiving the message, attaching the mobile device to the current control component; and
based on the radio link failure, delaying authentication of the mobile device such that authentication of the mobile device
is initiated subsequent to the attaching of the mobile device to the current control component to ensure that a communication
session in which the mobile device was engaged prior to the radio link failure is uninterrupted.
