Claim:
1. A method of synchronization validation in a wireless network, the method comprising: receiving, at a computing processor, terminal information from a first base station in the wireless network for a set of wireless terminals associated with the first base station; identifying, by the computing processor, the set of wireless terminals associated with the first base station based on the terminal information; instructing, by the computing processor, the set of wireless terminals or a subset of the wireless terminals associated with the first base station to return network measurements; instructing, by the computing processor, at least one wireless terminal from the set of wireless terminals or the subset of wireless terminals to take network measurements on a random access channel during uplink time slots, wherein the random access channel is configured to allow access to the wireless network by the at least one wireless terminal and is associated with a forbidden area where transmission is forbidden, the at least one wireless terminal including a transmitter and a receiver, wherein the transmitter is configured to be inactive in the forbidden area and the receiver is configured to be active in the forbidden area; receiving, at the computing processor, a network measurement from at least one of the wireless terminals in the wireless network instructed by the computing processor to return network measurements, the network measurement made with respect to at least the first base station; and determining, at the computing processor, a synchronization state of at least one base station based on the received network measurements.
