Abstract
A method and apparatus for facilitating handoff from a network access point (NAP) that is arranged and constructed to provide service to a communications unit (CU) in a frequency hopped communications system. The operations that are performed are providing service between the CU and the NAP on a connection using a first frequency hopping pattern (FHP); determining that the connection is suitable for discontinuation based on RSSI or load; sending a first message including an ID for the NAP and schedule for the CU to neighboring NAPS, the message requesting assistance with the service on tho first FHP; and receiving a second message from a neighboring NAP, arranged and constructed to provide connections to CUs using a second FHP, the second message indicating that assistance can be provided by the neighboring NAP.
