Abstract
An independent wideband pilot channel transmitter is located in each cell of a frequency division multiple access communications system which is adjacent to a code division multiple access communications system. Operation of the independent wideband pilot channel transmitter is controlled by a mobile switching center of the code division multiple access communications system. Wideband pilot channel broadcasts from the independent wideband pilot channel transmitters are then monitored by dual mode mobile stations in accordance with mobile assisted handoff (MAHO) procedures for the purpose of identifying target cells in the frequency division multiple access communications system which are suitable for handoff.
