S101, obtain contention access load, contention access load with received on Physical Random Access Channel The quantity of random access preamble message is related.

The Physical Random Access Channel (PRACH, Physical Random Access Channel) is user equipment The channel accessed first when calling is initiated, and then RRC connection is established according to the instruction of base station equipment, is the key that calling procedure.

Specifically, the mode that base station equipment obtains contention access load can be realized by following two step:

Step 1, the number for the random access preamble message that statistics receives on the Physical Random Access Channel of specified quantity Amount.

In the embodiment of the present invention, the specified quantity, the value of PrachStatNum are indicated with parameter PrachStatNum It can be preset by designer, such as setting PrachStatNum=10 etc..

During specific implementation, the mode that sliding window statistics can be used in base station equipment counts PrachStatNum physical accidental The quantity of received random access preamble message on channel is accessed, mode is as follows:

First after receiving a Physical Random Access Channel every time, a sliding window is created；Then in i-th of sliding window, Count the number of the random access preamble message received on the i-th to the i-th+PrachStatNum-1 Physical Random Access Channels Amount, is denoted as ConPreambleNum.For example, it is assumed that PrachStatNum=10, then base station equipment is in the 3rd sliding window, statistics The quantity of the random access preamble message received on the 3rd to the 12nd Physical Random Access Channel.

Step 2, the contention access load is calculated, contention access load is equal to the quantity and finger of random access preamble message The ratio of fixed number amount.

During specific implementation, contention access load=ConPreambleNum/PrachStatNum.

S102, obtains flow control condition information, and the flow control condition information is related to the quantity of the MSG3 of flow control.

Specifically, the mode that base station equipment obtains flow control condition information can be realized by following four step:

Step 1, the quantity of the MSG3 of the quantity and flow control of received MSG3 in the at the appointed time period is counted.

Optionally, the quantity of the received MSG3 of base station equipment includes sum below:

1. the quantity of wireless resource control connection request (the RRC Connection Request) message received；

2. wireless heterogeneous networks reconstruction request (the RRC Connection Reestablishment received Request) the quantity of message.

Again optional, the quantity of the MSG3 of base station equipment flow control includes sum below:

1. the quantity of wireless heterogeneous networks connection refusal (the RRC Connection Reject) message sent；

2. the wireless heterogeneous networks sent reestablishment rejected (RRC Connection Reestablishment Reject) disappear The quantity of breath；

3. being not responding to the number of the wireless resource control connection request message；

4. being not responding to the number of the wireless heterogeneous networks reconstruction request message.

During specific implementation, when each FlowCtrlStatPeriod starts, ReceiveMsg3Num=0 is initialized And FlowCtrlMsg3Num=0, in the FlowCtrlStatPeriod, base station equipment often receives a wireless heterogeneous networks After connection request message, or after receiving a wireless heterogeneous networks reconstruction request message, ReceiveMsg3Num=is executed ReceiveMsg3Num+1；After base station equipment often receives a wireless heterogeneous networks connection refused message, or receive a nothing After the reestablishment rejected message of line resources control, or carry out after being once not responding to wireless resource control connection request message, or carry out one It is secondary be not responding to wireless heterogeneous networks reconstruction request message after, execute FlowCtrlMsg3Num=FlowCtrlMsg3Num+1.

Step 2, MSG3 flow control ratio is calculated, the flow control ratio is equal to the quantity of the MSG3 of flow control with received MSG3's The ratio of quantity.

During specific implementation, MSG3 flow control ratio=FlowCtrlMsg3Num/ReceiveMsg3Num.

Step 3, MSG3 flow control ratio upper limit value and MSG3 flow control ratio lower limit value are inquired.

In the embodiment of the present invention, the MSG3 flow control ratio upper limit value is indicated with parameter FlowCtrlMsg3HighRatio, The MSG3 flow control ratio lower limit value is indicated with parameter FlowCtrlMsg3LowRatio, wherein The value of FlowCtrlMsg3HighRatio and FlowCtrlMsg3LowRatio can be preset by designer.

Step 4, according to MSG3 flow control ratio respectively with MSG3 flow control ratio upper limit value and MSG3 flow control ratio lower limit value Size relation determines the flow control condition information.

During specific implementation, if MSG3 flow control situation is higher than MSG3 flow control ratio upper limit value, it is determined that flow control situation letter Breath is high flow control situation；If MSG3 flow control situation is lower than MSG3 flow control ratio lower limit value, it is determined that flow control condition information is low stream Control situation.

If FlowCtrlMsg3Num/ReceiveMsg3Num=0, keep FlowCtrlMSG3Sign constant；

If FlowCtrlMsg3Num/ReceiveMsg3Num > FlowCtrlMsg3HighRatio, enables FlowCtrlMSG3Sign=1；

If FlowCtrlMsg3Num/ReceiveMsg3Num < FlowCtrlMsg3LowRatio, enables FlowCtrlMSG3Sign=-1；

Otherwise, FlowCtrlMSG3Sign=0 is enabled.

S103 adjusts the numerical value of index avoidance according to contention access load and the flow control condition information.

During specific implementation, base station equipment first inquires contention access upper loading limit value and contention access load lower limit value, And the maximum value and minimum value of index avoidance, then execute:

When the numerical value of index avoidance is less than the maximum value of index avoidance, loaded if contention access load is higher than contention access Upper limit value or flow control condition information are high flow control situation, then increase the numerical value of index avoidance；

When the numerical value of index avoidance is greater than the minimum value of index avoidance, if contention access load is loaded lower than contention access Lower limit value or flow control condition information are low flow control situation, then reduce the numerical value of index avoidance.

Optionally, referring to table 1, the embodiment of the present invention can set index avoidance according to the description in 3GPP agreement Maximum value be 12, and set the minimum value of index avoidance as 0.
