Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Method embodiment
According to embodiments of the invention, provide a kind of up-downgoing reallocating method.Fig. 1 is the flow chart according to the up-downgoing reallocating method of the embodiment of the invention, and as shown in Figure 1, this method comprises that following step S102 is to step S104:
Step S102, any one direction in upstream or downstream satisfies under the situation of channel migration condition, judges whether the another one direction in the upstream or downstream satisfies the channel migration condition in the section at the fixed time.
For example, timer can be set predetermined amount of time is carried out timing, and judge according to timer whether the another one direction in the upstream or downstream satisfies the channel migration condition in the section at the fixed time.Particularly, configuration timer time in backstage is T, when current uses of business DCH/DCH channel bearing business, is in certain speed state, and any one direction of upstream or downstream satisfies earlier and raises or when reducing speed, then start timer T.
Wherein, the channel migration condition comprises: raise speed, downward modulation speed.Raising speed can comprise one of following: the buffer area traffic carrying capacity surpasses first thresholding, throughput is measured and surpassed second thresholding; Downward modulation speed can comprise one of following: the buffer area traffic carrying capacity is lower than the 3rd thresholding, the throughput measurement is lower than the 4th thresholding; Wherein, first thresholding is higher than the 3rd thresholding, and second thresholding is higher than the 4th thresholding.
That is to say any one that the satisfied triggering factors that raises speed is following several factors or multiple:
(1) the buffer area data surpass appointment 4A thresholding, and this 4A thresholding can be the backstage configuration, also can be certain value of fixing.
(2) throughput is measured and is surpassed appointment A thresholding, and this A thresholding can be the backstage configuration, also can be certain value of fixing.
And, any one that the satisfied triggering factors of reducing speed is following several factors or multiple:
(1) the buffer area data are lower than appointment 4B thresholding, and this 4B thresholding can be the backstage configuration, also can be certain value of fixing.
(2) the throughput measurement is lower than appointment B thresholding, and this B thresholding can be the backstage configuration, also can be certain value of fixing.
Step S104 is if judged result, is then carried out the operation of up-downgoing reprovision for being.If judged result then carry out the reprovision operation of the direction that satisfies the channel migration condition in the upstream or downstream, and control timer stops timing for not.
Particularly, before timer T was overtime, the another one direction also satisfied the condition (raising or downward modulation) of channel migration, then carries out one step of up-downgoing reprovision; After when the super T of timer, the another one direction does not still satisfy the condition (raising or downward modulation) of channel migration, then only carries out the unidirectional reprovision of upstream or downstream.
By this embodiment, the strategy of one step of a kind of up-downgoing reprovision has been proposed, reached and reduced the mutual purpose of space interface signaling, can reduce mutual flow process of space interface signaling and time, and reduce the risk of call drop because the signaling reprovision causes eating dishes without rice or wine.
