1. A cell correlation method for correlating cells in first and second access networks, the method comprising:
sending a cell identification request from the first access network to the second access network, the cell identification request including a user terminal identification of a user terminal attempting to connect to a cell in the first access network;
receiving, responsive to the cell identification request, a cell identification of a last known cell in the second access network in which the user terminal was present; and
correlating the received cell identification with the cell in the first access network.
