Abstract:
A system for handing off communications with a mobile station from a first antenna to a second antenna, the system comprising:a first handoff mechanism for switching between the first antenna and the second antenna when at least one or both of the strength of the signal from the second antenna relative to the mobile station is greater than or equal to a first system parameter, and the difference between the strength of the signal from the second antenna relative to the mobile station and the strength of the signal from the first antenna relative to the mobile station is greater than or equal to a second system parameter; and a second handoff mechanism for switching between the first antenna and the second antenna when the difference between the strength of the signal from the second antenna relative to the mobile station and the strength of the signal from the first antenna relative to the mobile station is greater than or equal to the second system parameter plus a second hysterisis parameter.
