When the big 6db of number intensity, confirmation electronic equipment is unsatisfactory for antenna switching condition adjusted, switches without antenna, so that second
When antenna is run within a preset time, frequent switching is prevented.
Meanwhile after the second antenna of operation is switched to first antenna operation, before handoff threshold value can remain as increase
Handoff threshold value, such as 6db.When need in next section of preset time, when antenna meets preset operating conditions in operation, just tune
All day, line switching condition, that is, increased handoff threshold value.
It is understood that if the antenna amount of electronic equipment is greater than 2, within a preset time, if the second antenna is cut
It changes, in addition to first antenna can be switched to from the second antenna, other antennas can also be switched to.When being switched to other antennas,
It needs for the default measured value of other antennas to be compared with the default measured value of running second antenna.Switching over
When the judgement of condition, the default measured value of running antenna and to be switched antenna is compared always.Only work as operation
In antenna default measured value it is smaller than the default measured value of to be switched antenna, and the default measured value of the antenna with switching with
The difference of the default measured value of running antenna is greater than current handoff threshold value, i.e. the absolute value of the difference of the two is greater than current
Handoff threshold value when, just switch over.Meanwhile the handoff threshold value of increase can be definite value, it can also be according to electronic equipment
Operating condition is the value of variation, such as switches threshold value in first preset time and be increased to 9db, in second preset time
Handoff threshold value is increased to 8db.
After the ss embodiment of the present invention five is by switching to the operation of the second antenna by first antenna, preset when the second antenna meets
When service condition, increase handoff threshold value, i.e., when the default measured value of the default measured value of first antenna and the second antenna is big
When handoff threshold value after increase, just confirm that electronic equipment meets antenna switching condition adjusted.If first antenna is pre-
If the default measured value of measured value and the second antenna is not more than the handoff threshold value after increasing, the operation of the second antenna is kept, from
And antenna switching time is extended, avoid the frequent switching of antenna.
