Described first, connecting queue is described hysteresis while connecting queue, obtains the second frame error rate constantly of first before the first compensation constantly, and wherein, described the first compensation is constantly that frame error rate is for the first time lower than moment of described default frame error rate.

4. method as claimed in claim 3, is characterized in that, after second frame error rate in first moment at quarter before described acquisition the first compensation constantly, described method also comprises:

Based on described the second frame error rate, obtain the second compensation share;

Based on described the second compensation share, actual schedule weights are brought up to the 3rd scheduling weights from described the first scheduling weights.

5. method as claimed in claim 3, is characterized in that, described, judges whether described the first connection queue is that after hysteresis connects queue, described method also comprises:

When described the first connection queue is not described hysteresis connection queue, keeping actual schedule weights is described the first scheduling weights.

6. a node device, is applied in wireless network, and described node device has at least one the connection queue that comprises the first connection queue, it is characterized in that, described node device comprises:

First obtains unit, in first moment, when the described first assurance scheduling weights that connect queue are the first scheduling weights, obtains the first frame error rate of described the first connection queue;

The first judging unit, for judging whether described the first frame error rate is more than or equal to a default frame error rate;

The first control unit, for when described the first frame error rate is more than or equal to described default frame error rate, is reduced to the second scheduling weights by actual schedule weights from described the first scheduling weights.

7. node device as claimed in claim 6, is characterized in that, described the first control unit specifically comprises:

First obtains subelement, for when described the first frame error rate is more than or equal to described default frame error rate, based on described the first frame error rate, obtains the first compensation share;

First controls subelement, for based on described the first compensation share, actual schedule weights is reduced to described the second scheduling weights from described the first scheduling weights.

8. node device as claimed in claim 6, is characterized in that, described node device also comprises:

The second judging unit, for when described the first frame error rate is less than described default frame error rate, judges whether described the first connection queue is to lag behind to connect queue;

Second obtains unit, for when described the first connection queue is described hysteresis connection queue, obtain the second frame error rate constantly of first before the first compensation constantly, wherein, described the first compensation is constantly that frame error rate is for the first time lower than moment of described default frame error rate.

9. node device as claimed in claim 8, is characterized in that, described node device also comprises:

The 3rd obtains unit, for based on described the second frame error rate, obtains the second compensation share;

The second control unit, for based on described the second compensation share, brings up to the 3rd scheduling weights by actual schedule weights from described the first scheduling weights.

10. node device as claimed in claim 8, is characterized in that, described node device also comprises:

The 3rd control unit, for when described the first connection queue is not described hysteresis connection queue, keeping actual schedule weights is described the first scheduling weights.
