Claim:
A method, comprising: transmitting a first measurement message comprising a layer 3 service data unit to a radio access network in a wireless network, wherein transmitting the first message comprises at least: forming a layer 2 protocol data unit from the layer 3 service data unit; flagging the layer 2 protocol data unit to indicate requiring acknowledgement; transmitting the layer 2 protocol data unit using a layer 1 transmission protocol across a radio frequency channel to the radio access network; and re-transmitting the layer 2 protocol data unit when no acknowledgement is received within a pre-determined time interval; storing the first measurement message pending receipt of an acknowledgement of the first measurement message from the radio access network; before receiving the acknowledgement to the first measurement message from the radio access network, determining at least one parameter included in the first measurement message requires updating; deleting the stored pending first measurement message; and transmitting a second measurement message to the radio access network in the wireless network, the second measurement message including an updated value for the at least one parameter in the first measurement message.
