  • Method for providing hand-offs in a frequency hopping communication system
    Patent number: 5446769
    Abstract: A method for handing off user devices (131-134) between network control processors (110, 120) in a frequency hopping communication system (100) includes establishing a set of synchronization frequencies (A-D) for use by said NCPs (110, 120), informing the plurality of user devices (131-134) of said synchronization frequencies (A-D) and assigning a synchronization frequency (A, B, C or D) to each respective NCP, each NCP transmitting synchronization information at its assigned synchronization frequency (A, B, C or D) during each hopping dwell (1-82). Upon a determination that a user device hand-off is necessary, said user device in question (133) tunes to a synchronization frequency (B) different from the synchronization frequency (A) employed by the currently serving NCP (110) and synchronizes its operation to the NCP (120) transmitting synchronization information on the tuned to synchronization frequency (B).
