Fig. 3 is the schematic flow sheet of one embodiment of the method for gravity treatment carrier wave of the present invention. With reference to Fig. 3, the method for the present embodiment can include:
Step S301, user terminal disappear from broadcast when the broadcast of network side transmission is received Amount of bias offset and high priority carrier signal quality thresholding are extracted in breath.Wherein, broadcast disappears Breath is specifically as follows system broadcast message (System Information Block 5, SIB5) message.
Step S302, user terminal randomly generate random number R, the wherein span of random number R For 0≤R≤1, user terminal only in the new cell of gravity treatment to, is just randomly generated once again Random number, otherwise user terminal do not change random number.
Step S303, user terminal utilize amount of bias offset, random number R and high priority carrier wave Signal quality thresholding, obtains carrier wave gravity treatment thresholding.
Step S304, user terminal is by current high priority carrier signal quality and carrier wave gravity treatment thresholding It is compared, and according to comparative result gravity treatment carrier wave.If current high priority carrier signal quality is big In carrier wave gravity treatment thresholding, then execution step 305;If current high priority carrier signal quality is not more than Carrier wave gravity treatment thresholding, then execution step 306.
Step S305, user terminal is performed will be currently used low priority level carrier wave gravity treatment paramount excellent The step of first level carrier wave.Afterwards, other steps of the present embodiment are no longer performed.
Step S306, user terminal perform the step for continuing resident currently used low priority level carrier wave Suddenly.
In one embodiment, believed using amount of bias offset, random number R and high priority carrier wave Number quality threshold, can include the step of obtain carrier wave gravity treatment thresholding:
Using formula Th=Threshx,High+ offset × R, user terminal calculate carrier wave gravity treatment thresholding Th, Wherein, Th be carrier wave gravity treatment thresholding, Threshx,HighFor high priority carrier signal quality thresholding.
Fig. 4 illustrates the principle schematic of the method for gravity treatment carrier wave of the present invention.With reference to Fig. 4, figure In 4, two solid ovals of upper row represent cell 1, and two solid ovals of lower row represent cell 2, Cell 1 has carrier wave f1, and cell 2 has carrier wave f2, and the wherein priority of f1 is excellent higher than f2 First level, the user terminal in cell 1 and cell 2 are in Idle state, when user terminal needs weight When selecting carrier wave:
User terminal receives the broadcast that network side sends, and extracts in Fig. 4 from broadcast Amount of bias offset and high priority carrier signal quality thresholding of entity bidirectional arrow indication, and with Machine produces random number R, and the wherein span of random number R is 0≤R≤1;User terminal is utilized Amount of bias offset, random number R and high priority carrier signal quality thresholding, obtain carrier wave gravity treatment Thresholding (as shown in the irregular curve in Fig. 4), compared to high priority carrier signal quality thresholding Threshx,High(as shown in the dotted line frame in Fig. 4), as carrier wave gravity treatment thresholding is when being calculated The random number of introducing, i.e. Th=Threshx,High+ offset × R, therefore carrier wave gravity treatment thresholding is not solid Definite value, wherein, when the random number that user terminal is randomly generated is larger, cause carrier wave gravity treatment thresholding Become big, so as to cause current high priority carrier signal quality good user terminal also not necessarily Can gravity treatment on high priority carrier wave.Conversely, the random number randomly generated when user terminal is less When, cause carrier wave gravity treatment thresholding to diminish, so as to the user terminal for causing some dtr signals on the contrary can Enough meet carrier wave gravity treatment thresholding, so as in gravity treatment to the other carrier wave of high priority.So as to be prevented effectively from The substantially uneven problem of each carrier load.
Illustrate by taking user terminal A 1, A2 and A3 in Fig. 4 as an example below.User terminal A1 and A2 current signal qualities preferably, if by prior art can gravity treatment to high priority carrier wave On.Due to introducing random number R in the present invention, the random number R of user terminal A 1 is set here Larger, then calculated carrier wave gravity treatment threshold value is also big, so causes user terminal A 1 final not Energy gravity treatment is on high priority carrier wave.If the random number R of user terminal A 2 is less, count The carrier wave gravity treatment threshold value for obtaining is also little, so cause user terminal A 2 finally can gravity treatment to high On priority level carrier wave.Although it can thus be seen that user terminal A 1 and A2 current signal matter Amount all very well, but be finally 2 gravity treatment of user terminal A on high priority carrier wave, and user terminal A1 is still resided on the other carrier wave of former low priority.
For user terminal A 1 and A3, the signal quality of user terminal A 1 is better than The signal quality of user terminal A 3.As the random number R of user terminal A 1 is larger, then calculate The carrier wave gravity treatment threshold value for arriving is also big, so causes user terminal A 1 to be finally unable to gravity treatment preferential to height On rank carrier wave.And although the current signal quality of user terminal A 3 is poorer than user terminal A 1, But due to the random number R of user terminal A 3 it is less, then calculated carrier wave gravity treatment threshold value It is little, so cause user terminal A 3 it is final also can gravity treatment on high priority carrier wave.
As can be seen here, in the prior art shown in Fig. 1, as long as the user terminal in cell 2 is full (that is, current high priority carrier signal quality is more than predetermined high priority to the predetermined condition of foot Carrier signal quality thresholding), can gravity treatment arrived on the other carrier wave of high priority, and reside in low User terminal on the carrier wave of priority level is on the low side, so as to cause carrier load unbalanced.And use After the method for the gravity treatment carrier wave of the application, due to introducing random number, therefore signal good user's end End may not necessarily gravity treatment on high priority carrier wave, and the user terminal of signal difference is possible to gravity treatment and arrives On high priority carrier wave.So that residing in the carrier wave of high priority and residing in low priority Carrier wave user terminal quantity it is more balanced.
