It should be noted that policy control center allows to lift UP bandwidth to be adjusted to the instruction that is used for that the CP is sent Response is carried in a message, the CP to UP to be adjusted forward this be used for indicate allow the sound that lifts UP bandwidth to be adjusted It should be carried in a message, the protocol type of the two message be able to can also be differed with identical.

4043：This of UP reception CP forwardings to be adjusted is used to indicate to allow the response for lifting UP bandwidth to be adjusted.

UP to be adjusted obtains UP to be adjusted increasing bandwidth, and UP to be adjusted current grant bandwidth is revised as treating The UP of adjustment current grant bandwidth and UP to be adjusted increasing bandwidth sum.

If this is used to indicate to allow the increasing bandwidth for carrying UP to be adjusted in the response for lifting UP bandwidth to be adjusted, Then the step of UP to be adjusted acquisition UP to be adjusted increasing bandwidth can be：

UP to be adjusted obtains UP's to be adjusted from the response that this is used to indicate to allow to lift UP bandwidth to be adjusted Increasing bandwidth.

If this is used to indicate the increasing bandwidth for allowing the response for lifting UP bandwidth to be adjusted not carry UP to be adjusted, Then the step of UP to be adjusted acquisition UP to be adjusted increasing bandwidth can be：

UP to be adjusted obtains UP to be adjusted increasing bandwidth from UP to be adjusted signing information.

Further, the method for control network section bandwidth provided in an embodiment of the present invention can also comprise the following steps：

Step 405：Policy control center UP to be adjusted current grant bandwidth is revised as the current of UP to be adjusted Bandwidth and UP to be adjusted increasing bandwidth sum.

It should be noted that if policy control center determines that all AN's of the UP controls belonging to AN to be adjusted is current Authorized bandwidth and AN to be adjusted increasing bandwidth sum are more than all AN of UP controls signing total bandwidth, and determine working as UP Preceding authorized bandwidth is not more than CP signing maximum bandwidth, and AN to be adjusted bandwidth is lifted by lifting the bandwidth of the UP.

It should be noted that either directly lift AN to be adjusted bandwidth, or by lift the bandwidth of the UP come AN to be adjusted bandwidth is lifted, is required for current grant bandwidth and the AN to be adjusted increasing bandwidth for meeting AN to be adjusted Sum is not more than AN to be adjusted signing maximum bandwidth.

Referring to Fig. 6, this method includes：

Step 601：What the AN for controlling AN to be adjusted CP receptions to be adjusted was sent is used to lift AN bandwidth to be adjusted Lift bandwidth request.

In 5G networks, cutting into slices for one includes at least one CP, and each CP at least one CP controls at least one UP, Each UP at least one UP includes at least one AN.

The each UP for each CP controls that the section includes signing information is stored in policy control center, in policy control The signing information for each AN that each UP includes also is stored in the heart；The signing information for any AN that the section includes comprises at least should Any AN increasing bandwidth and signing maximum bandwidth, can also include bandwidth of successively decreasing；The increasing bandwidth of any AN is any with this AN bandwidth of successively decreasing can be with equal, can also be unequal；Initial bandwidth can also be included in the signing information of any AN；This One AN initial bandwidth is between the signing minimum bandwidth of any AN and signing maximum bandwidth；In order to save Internet resources, Increase network utilization, the initial bandwidth of any AN is equal with the signing minimum bandwidth of any AN.

For any CP that any section in 5G networks includes in initialization, the CP obtains from policy control center should Each UP of CP controls signing information, the label for each AN that each UP of CP controls includes are obtained from policy control center About information.

For any AN that each UP of CP controls includes in initialization, the AN obtains the signing letter of the AN from the CP Breath, the signing information of the AN include the initial bandwidth of the AN, signing maximum bandwidth, signing minimum bandwidth, increasing bandwidth and successively decreased Bandwidth.

Further, the AN obtains the initial bandwidth of the AN from the signing information of the AN, and the initial bandwidth of the AN is true It is set to the current grant bandwidth of the AN.

In same section, the initial bandwidth for each AN that any CP includes can be with equal in the section, can not also phase Deng；The signing maximum bandwidth for each AN that any CP includes can be with equal in the section, can also be unequal；It is any in the section The signing minimum bandwidth for each AN that CP includes can be with equal, can also be unequal；Each AN that any CP includes in the section Bandwidth of successively decreasing can be with equal, can also be unequal.

With the development of business, in any AN customer volume increase, any AN needs to lift the current of any AN Authorized bandwidth, it would be desirable to which the AN for lifting AN current grant bandwidth is referred to as AN to be adjusted, performs step 601.

AN to be adjusted is detecting AN to be adjusted currently practical bandwidth and AN to be adjusted current grant bandwidth Between ratio when reaching default promotion threshold value, to the elevator belt for controlling AN to be adjusted CP to send to be lifted AN bandwidth to be adjusted Width request；Control AN to be adjusted CP to receive the lifting bandwidth for being used to be lifted AN bandwidth to be adjusted that AN to be adjusted is sent to ask Ask.

It should be noted that at least carrying AN to be adjusted mark in the lifting bandwidth request, it can also carry and wait to adjust Whole AN increasing bandwidth.

AN to be adjusted increasing bandwidth can be the increasing bandwidth in AN to be adjusted signing information；AN to be adjusted Increasing bandwidth can not also for AN to be adjusted signing information in increasing bandwidth, also, should set reasonably be incremented by band Width, ensure that AN to be adjusted will not frequently adjust AN to be adjusted current grant bandwidth.

Step 602：AN to be adjusted CP is controlled to obtain AN to be adjusted increasing bandwidth.

If the lifting bandwidth request carries AN to be adjusted increasing bandwidth, this step can be：

AN to be adjusted CP is controlled to obtain AN to be adjusted increasing bandwidth from the lifting bandwidth request.

If the lifting bandwidth request does not carry AN to be adjusted increasing bandwidth, this step can be：

AN to be adjusted CP is controlled to obtain AN to be adjusted signing information, AN to be adjusted signing information includes treating The AN of adjustment increasing bandwidth, the AN of adjustment increasing bandwidth is obtained from AN to be adjusted signing information.

Before this step, control AN to be adjusted CP to be obtained from policy control center and control AN to be adjusted CP to control Each AN signing information, store each AN signing information；AN to be adjusted CP is then controlled to obtain AN to be adjusted label About information the step of can be：

This is used to indicate to allow the mark at least carrying AN to be adjusted in the response for lifting AN bandwidth to be adjusted, may be used also To carry AN to be adjusted increasing bandwidth.

It should be noted that if AN to be adjusted lifts AN to be adjusted to being used for of sending of the CP for controlling AN to be adjusted Bandwidth lifting bandwidth request in carry AN to be adjusted increasing bandwidth, then this is used to indicate to allow to lift AN to be adjusted AN to be adjusted increasing bandwidth can not be carried in the response of bandwidth.

If the lifting of AN to be adjusted to the bandwidth for lifting AN to be adjusted for the CP transmissions for controlling AN to be adjusted AN to be adjusted increasing bandwidth is not carried in bandwidth request, then this is used to indicate to allow the sound for lifting AN bandwidth to be adjusted Need to carry AN to be adjusted increasing bandwidth in answering.

AN to be adjusted, which receives the instruction that is used for for controlling AN to be adjusted CP to send, to be allowed to lift AN bandwidth to be adjusted Response, AN to be adjusted current grant bandwidth and passing for AN to be adjusted are revised as by AN to be adjusted current grant bandwidth Increase bandwidth sum.

Step 605：AN to be adjusted CP is controlled by the transmission network between the UP belonging to AN to be adjusted and AN to be adjusted The bandwidth of network is revised as AN to be adjusted current grant bandwidth and AN to be adjusted increasing bandwidth sum.

Control AN to be adjusted CP that AN to be adjusted current grant bandwidth is revised as to AN to be adjusted current bandwidth With AN increasing bandwidth sum.Notification strategy control centre is by the transmission between the UP belonging to AN to be adjusted and AN to be adjusted The bandwidth of network is revised as AN to be adjusted current grant bandwidth and AN to be adjusted increasing bandwidth sum.

Policy control center is changed by the bandwidth of the transmission network between the UP belonging to AN to be adjusted and AN to be adjusted The step of increasing bandwidth sum of current grant bandwidth and AN to be adjusted for AN to be adjusted can be：

Policy control center sends modification request to SDN-C, and the modification is asked for changing the UP belonging to AN to be adjusted The bandwidth of transmission network between AN to be adjusted, and modification request carries AN to be adjusted mark and AN to be adjusted Affiliated UP mark；SDN-C receives the modification request that policy control center is sent, and according to AN to be adjusted mark and The mark of UP belonging to AN to be adjusted, by the bandwidth of the transmission network between the UP belonging to AN to be adjusted and AN to be adjusted It is revised as AN to be adjusted current grant bandwidth and AN to be adjusted increasing bandwidth sum.

Step 606：AN to be adjusted CP is controlled to determine the current grant for all AN that the UP belonging to AN to be adjusted is controlled Bandwidth and AN to be adjusted increasing bandwidth sum are more than all AN of UP controls signing total bandwidth, and determine that the current of UP is awarded Weigh signing maximum bandwidth of the bandwidth no more than the UP belonging to AN to be adjusted.

Further, if it is determined that all AN of UP belonging to AN to be adjusted control current grant bandwidth with it is to be adjusted AN increasing bandwidth sum be more than UP controls all AN signing total bandwidth, and determine that UP current grant band is wider than and treated The signing maximum bandwidth of UP belonging to the AN of adjustment, sent to AN to be adjusted for indicating not allow to lift AN's to be adjusted The response of bandwidth.

Step 607：AN to be adjusted CP is controlled to be sent to policy control center for lifting the UP belonging to AN to be adjusted The lifting bandwidth request of bandwidth.

What the CP that policy control center receives control AN to be adjusted was sent is used to lift the UP bandwidth belonging to AN to be adjusted Lifting bandwidth request, control the bandwidth of the UP belonging to AN to be adjusted according to the method for above example 3.

If policy control center determines to be lifted UP bandwidth belonging to AN to be adjusted, policy control center to Control AN to be adjusted CP to send the response for not allowing to be lifted the UP bandwidth belonging to AN to be adjusted for instruction, then control and wait to adjust Whole AN CP is sent for indicating not allow the response for lifting AN bandwidth to be adjusted to AN to be adjusted.

If policy control center determines to be lifted UP bandwidth belonging to AN to be adjusted, policy control center is to control The CP for making AN to be adjusted sends the response for allowing to be lifted the UP bandwidth belonging to AN to be adjusted for instruction, performs step 608.

Step 608：Control that AN to be adjusted CP receives that policy control center sends be used for instruction allow to be lifted it is to be adjusted AN belonging to UP bandwidth response, the current grant bandwidth of the UP bandwidth belonging to AN to be adjusted is revised as AN to be adjusted The current bandwidth of affiliated UP bandwidth and the increasing bandwidth sum of the UP bandwidth belonging to AN to be adjusted, then perform step 604.
