Business when business is less than after guarantee information rate successfully increases, then reduce between baseband processing unit and Remote Radio Unit
Guarantee information rate.
Step 206, judge that the guarantee information rate between baseband processing unit and Remote Radio Unit after reducing meets
The transmission bandwidth demand between baseband processing unit and Remote Radio Unit before operating mode upgrading, if satisfied, then entering step
Rapid 207；If not satisfied, then entering step 205.
In this step, reduce guarantee information rate between baseband processing unit and Remote Radio Unit and then
Judge whether the guarantee information rate between baseband processing unit and Remote Radio Unit after reducing meets operating mode upgrading
Transmission bandwidth demand between preceding baseband processing unit and Remote Radio Unit.If satisfied, then illustrating the guarantee letter after reducing
Breath rate is fully able to guarantee the transmission bandwidth before operating mode degradation, at this point, entering step 207, i.e., to baseband processing unit
Or Remote Radio Unit sends signaling or instruction, wherein carries baseband processing unit or remote radio list in signaling or instruction
The downgrade information of the operating mode of member；If not satisfied, then illustrating that the guarantee information rate after reducing cannot be guaranteed operating mode
Transmission bandwidth before degradation repeats to reduce baseband processing unit and radio frequency according to preset condition at this point, then entering step 205
Guarantee information rate between extension unit.
Step 207, baseband processing unit or remote radio are carried to baseband processing unit or Remote Radio Unit transmission
The signaling or instruction of the downgrade information of the operating mode of unit.
Step 208, the guarantee information rate between baseband processing unit and Remote Radio Unit increases failure, subsequently into
Step 209.
Step 209, nothing is transmitted by distributing to the peak information rate between baseband processing unit and Remote Radio Unit
Line signal, and whether the packet loss for detecting packet transmission apparatus is greater than a preset threshold, if being not more than, enters step 202, if
It is greater than, then enters step 207.
In this step, when the guarantee information rate between baseband processing unit and Remote Radio Unit increases failure
Afterwards, packet transmission apparatus can only be transmitted using distribution to the peak information rate between baseband processing unit and Remote Radio Unit
Wireless signal.Meanwhile whether packet transmission apparatus detection packet loss is greater than a preset threshold.If being not more than, illustrate transmission network
Network resource not congestion, the operating mode after upgrading can be kept, and can continue to attempt to increase baseband processing unit and radio frequency is drawn
Guarantee information rate between remote unit, that is, enter step 202；If more than then illustrating that network transmission resource is limited, business is gathered around
Plug, transfer resource are unable to satisfy the demand of current wireless devices operating mode, at this time, it may be necessary to draw to baseband processing unit or radio frequency
Remote unit sends the signaling or instruction for carrying the downgrade information of operating mode of baseband processing unit or Remote Radio Unit, drop
The operating mode of low wireless device, that is, enter step 207.
The biography between baseband processing unit and Remote Radio Unit after the operating mode upgrading that the present embodiment passes through acquisition
Defeated bandwidth requirement information, according to the resource situation of packet transmission apparatus, i.e., according to all wireless devices on entire transmission link
Guarantee information rate whether be more than packet transmission apparatus transmission bandwidth ability, decide whether to increase distribution to Base-Band Processing list
Guarantee information rate between member and Remote Radio Unit.The present embodiment can be according to transmission bandwidth demand and packet transmission apparatus
Resource situation change distribution to the guarantee information rate between baseband processing unit and Remote Radio Unit, solve existing
The problem of transmission rate between baseband processing unit and Remote Radio Unit is constant rate of speed, works as bandwidth demand to solve
When smaller, transmission bandwidth caused by the transmission rate of fixed rate waste the problem of, reduce transmission cost, improve user's body
It tests.
