It is of course also possible to change RACH resource on the basis of RACH resource is increased, or become on the basis of RACH resource is reduced More RACH resource.

Wherein, the mode that network side equipment judges whether to need to adjust RACH resource has a lot, is set forth below several：

The number that mode one, the network side equipment collide according to RACH occurs in preset time period, judges whether to need Adjust RACH resource.

For example first threshold and Second Threshold can be set, wherein the first threshold is more than Second Threshold；

If the number that RACH collisions occur in preset time period is more than first threshold, described in the network side equipment increase The RACH resource of the cell of network side equipment management；

If the number that RACH collisions occur in preset time period is less than Second Threshold, described in the network side equipment reduction The RACH resource of the cell of network side equipment management.

In force, the period can be configured as needed, for example can set one day, half a day etc..First threshold With Second Threshold can rule of thumb, emulation etc. mode determine.

Here the number that RACH collisions occur refers to that the number of RACH collisions occurs for the Intra-cell of network side equipment management.

Mode two, the network side equipment according to the number of users in the different time sections cell determined by pre-known information, Judge whether to need to adjust RACH resource.

For example the 3rd threshold value and the 4th threshold value can be set, wherein the 3rd threshold value is more than the 4th threshold value；

If the number of users in the period cell being presently in is more than the 3rd threshold value, the network side equipment increases institute State the RACH resource of the cell of network side equipment management；

If the number of users in the period cell being presently in is less than the 4th threshold value, the network side equipment reduces institute State the RACH resource of the cell of network side equipment management.
