Claim of US Patent No. 10,602,565

1. A method performed by a first communication device for performing one or more actions to resolve a state mismatch between the first communication device and a second communication device operating in a communications network, the method comprising:transmitting a message to the second communication device, the message being associated with a subsequent state to a current state of the first communication device and a subsequent state to a current state of the second communication device,
upon transmitting the message, searching for one or more transmissions from the second communication device that are indicative of the state mismatch between the first communication device and the second communication device, wherein a time for the searching for the one or more transmissions is based on a time between transmission of a connection request message and transmission of a first data transmission to the second communication device, and
upon detection of the one or more transmissions,
performing the one or more actions to resolve the state mismatch, the performing of the one or more actions being according to one of:
a) the current state of the second communication device, and
b) a transition to a state different from the current state of the first communication device.
