Embodiment one
Fig. 3 is a kind of flow diagram one of base station switch method provided in an embodiment of the present invention, and this method is applied to eventually
End, comprising:
Step 101: determining the first switching base station according to the first preset rules, the first preset rules are for determining that terminal is mobile
Next base station corresponding to track is the first switching base station；
Wherein, the first switching base station is that terminal needs to be switched to neighboring community from the base station currently connected i.e. current base station
When base station, the biggish base station of switching probability.
You need to add is that the first preset rules are terminal previously according to actual needs for determining the first switching base station
Or user behavior determines.For example, if terminal measures signal quality in current neighboring community and is higher than what terminal currently connected
When base station, that is, current base station, terminal determines that the neighboring community is the first switching base station；Alternatively, shown in Figure 4, terminal will be measured
Itself motion track corresponding to next base station, that is, base station B be first switching base station.The embodiment of the present invention is default to first
The setting of rule is not particularly limited.
Step 102: the first signal data of the first switching of measurement base station；
Intelligible, the first signal data of the first switching base station is the quality that signal is transmitted in the first switching base station.
In practical application, terminal needs to be switched to another wireless coverage cell from the base station of a wireless coverage cell
It is too poor often caused by original used channel transmission quality and need to switch when base station.In this case, the first switching base
The first signal data stood is used to judge channel quality quality, so can determine whether to need to carry out base station switching.
Wherein, the first signal data of the first switching base station may include the received signal power of the first switching base station, the
The received signal to noise ratio of one switching base station, the frame error rate of the first switching base station, signal strength of the first switching base station etc..Certainly,
First signal data of one switching base station further includes other signal parameters, first letter of the embodiment of the present invention to the first switching base station
The concrete form of number is without limitation.
Step 103: when the first signal data is greater than pre-determined threshold, being repaired the first signal data according to the second preset rules
Second signal data are changed to, to increase the probability that terminal switches to the first switching base station；
Wherein, pre-determined threshold is that terminal is pre-set for judging whether the first switching base station is that terminal progress base station is cut
The to be switched base station being inclined to when changing.Pre-determined threshold can be set according to actual measured results or practical application scene
Set, the embodiment of the present invention to the specific value of pre-determined threshold without limitation.
It should be noted that the second preset rules are for modifying to the first signal data, to increase terminal to the
The probability of one switching base station switching.
In practical application, the first signal data is revised as second signal data according to the second preset rules, including a variety of
Mode, such as: it, can be by the priority tune of the first switching base station when the first signal data includes the priority of the first switching base station
It is whole to highest；Increase delay value in measurement result.The embodiment of the present invention does not limit the specific implementation of the second preset rules
It is fixed.
Certainly, terminal can also be modified by the information data to current base station, for example, increasing current base station most
Big Timing Advance (TA, time advanced), wherein TA value shows that more greatly terminal is remoter from current base station, increases current base
The TA value stood increases the probability that terminal switches to the first switching base station.
Further, the first signal data is revised as second signal data according to the second preset rules, specifically included: surveyed
Flow control one switches grade, and according to the corresponding relationship of the first switching grade and preset switching grade and modified values, by the first letter
Number increases corresponding modified values；Using the first signal data after increase as second signal data.
In practical application, terminal can according to need the first different switching grade of setting, and different the first switchings etc.
The corresponding different adjusted value of grade.For example, if the first switching grade is first level, i.e., the first switching grade highest one
When rank, corresponding different adjusted value is maximum adjusted value 20dB, that is to say, that if the first switching grade is first level,
First signal data is increased 20dB by terminal, thus using the numerical value after increase as second signal data.In this way, first
When switching the highest rank of grade, by significantly increasing the size of the first signal data, and then increase terminal to
The probability of first switching base station switching.
Illustratively, the method for the first switching of measurement grade, specifically includes: small in the signal data for monitoring current base station
When being equal at least about a default handoff threshold, according to the first default handoff threshold and preset handoff threshold and switching grade
Corresponding relationship, determine the first switching grade, the first default handoff threshold be at least one default handoff threshold with current base
The smallest default handoff threshold of the signal data difference stood.
