As the service is developed, the number of users in the UP is increased. The UP of the UP is required to increase the current authorized bandwidth of the UP. The UP of the current authorized bandwidth of the UP is called UP to be adjusted. 401.

Step 401 can be implemented by the following steps 4011-4013, including:

4011: The UP to be adjusted sends a boost bandwidth request to the CP, where the boost bandwidth request is used to increase the bandwidth of the UP to be adjusted, and the UP to be adjusted is controlled by the CP.

The UP to be adjusted sends a boost bandwidth request to the CP controlling the UP to be adjusted when the ratio between the current actual bandwidth of the UP to be adjusted and the current authorized bandwidth of the UP to be adjusted reaches a preset boost threshold. The CP forwards the enhanced bandwidth request to the policy control center, and the enhanced bandwidth request is used to increase the bandwidth of the UP to be adjusted.

The preset lifting threshold may be set and changed as needed. In the embodiment of the present invention, the preset lifting threshold is not specifically limited; for example, the preset lifting threshold may be 80% or 90% or the like.

The UP to be adjusted may further determine whether the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted is greater than the maximum bandwidth of the UP to be adjusted, before the UP is to be adjusted. The adjusted UP determines that the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted is not greater than the maximum contracted bandwidth of the UP to be adjusted, and step 4011 is performed.

4013: The Policy Control Center receives the elevated bandwidth request forwarded by the CP.

Step 402: The policy control center acquires an incremental bandwidth of the UP to be adjusted.

If the boost bandwidth request carries the incremental bandwidth of the UP to be adjusted, this step may be:

The policy control center obtains the incremental bandwidth of the UP to be adjusted from the elevated bandwidth request.

If the enhanced bandwidth request does not carry the incremental bandwidth of the UP to be adjusted, this step may be:

The policy control center obtains the subscription information of the UP to be adjusted. The subscription information of the UP to be adjusted includes the incremental bandwidth of the UP to be adjusted, and the incremental bandwidth of the adjusted UP is obtained from the subscription information of the UP to be adjusted.

Step 403: The policy control center determines that the sum of the current authorized bandwidth of all UPs controlled by the CP and the incremental bandwidth of the UP to be adjusted is not greater than the total subscription bandwidth of all UPs controlled by the CP, or determines all the slice control to which the CP belongs. The sum of the current authorized bandwidth of the UP and the incremental bandwidth of the UP to be adjusted is not greater than the total subscription bandwidth of all UPs controlled by the slice.

One slice includes at least one CP; the present invention can select a specific implementation of this step according to the number of CPs included in one slice:

If a slice includes a CP, this step can be implemented in the first manner. If a slice includes multiple CPs, this step can be implemented by the following first or second manner.

For the first implementation, this step can be:

The policy control center determines whether the sum of the current authorized bandwidth of all UPs controlled by the CP and the incremental bandwidth of the UP to be adjusted is not greater than the total subscription bandwidth of all UPs controlled by the CP; if the policy control center determines all UPs controlled by the CP The sum of the current authorized bandwidth and the incremental bandwidth of the UP to be adjusted is not greater than the total subscription bandwidth of all UPs controlled by the CP, and step 404 is performed.

Further, if the policy control center determines that the sum of the current authorized bandwidth of all UPs controlled by the CP and the incremental bandwidth of the UP to be adjusted is greater than the total subscription bandwidth of all UPs controlled by the CP, the policy control center sends the UP to the UP to be adjusted. The response indicating that the UP bandwidth to be adjusted is not allowed to be upgraded; the response sent by the UP receiving policy control center to indicate that the UP bandwidth to be adjusted is not allowed to be upgraded; the UP receiving policy control center to be adjusted is used to indicate It is not allowed to increase the response of the UP bandwidth to be adjusted, and does not adjust the current authorized bandwidth of the adjusted UP.

The step of the policy control center sending a response to the UP to be adjusted for indicating that the UP bandwidth to be adjusted is not allowed to be upgraded may be:

The policy control center sends a response to the CP for indicating that the UP bandwidth to be adjusted is not allowed to be upgraded, and is used to indicate that the response of the UP bandwidth that is not allowed to be upgraded is carried, and the identifier of the UP to be adjusted is carried; And the identifier of the UP to be adjusted is obtained from the response of the UP to be adjusted, and the identifier to be adjusted is adjusted according to the identifier of the UP to be adjusted. The UP forwards the response indicating that the UP bandwidth to be adjusted is not allowed to be boosted.

It should be noted that the response sent by the policy control center to the CP for indicating that the UP bandwidth to be adjusted is not allowed to be upgraded is carried in a message, and the CP forwards the UP to be adjusted to indicate that the upgrade is not allowed to be adjusted. The response of the UP bandwidth is carried in a message, and the protocol types of the two messages may be the same or different.

For the second implementation, this step can be:

The policy control center determines whether the sum of the current authorized bandwidth of all UPs of the slice control to which the CP belongs and the incremental bandwidth of the UP to be adjusted is not greater than the total subscription bandwidth of all UPs controlled by the slice; if the policy control center determines that the CP belongs to The sum of the current authorized bandwidth of all UPs controlled by the slice control and the incremental bandwidth of the UP to be adjusted is not greater than the total subscription bandwidth of all UPs of the slice control, and step 404 is performed.

Further, if the policy control center determines that the sum of the current authorized bandwidth of all UPs of the slice control to which the CP belongs and the incremental bandwidth of the UP to be adjusted is greater than the total subscription bandwidth of all UPs controlled by the slice, the policy control center is to be adjusted. The UP sends a response indicating that the UP bandwidth to be adjusted is not allowed to be upgraded; the UP transmission policy control center to be adjusted is used to indicate that the response of the UP bandwidth to be adjusted is not allowed to be promoted.

In the case of the foregoing two implementation manners, the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted is not greater than the maximum subscription bandwidth of the UP to be adjusted. Therefore, before performing step 403, the method further includes:

The policy control center determines whether the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted is not greater than the maximum subscription bandwidth of the UP to be adjusted; if the policy control center determines the current authorized bandwidth of the UP to be adjusted and to be adjusted The sum of the incremental bandwidths of the UPs is not greater than the maximum subscription bandwidth of the UP to be adjusted, and step 403 is performed.

If the policy control center determines that the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted is greater than the maximum bandwidth of the UP to be adjusted, the UP is sent to the UP to be adjusted to indicate that the UP bandwidth to be adjusted is not allowed to be upgraded. the response to.

If the UP to be adjusted sends a request for lifting bandwidth to the CP, the UP to be adjusted determines the UP to be adjusted. If the sum of the current authorized bandwidth and the incremental bandwidth of the UP to be adjusted is not greater than the maximum subscription bandwidth of the UP to be adjusted, the policy control center may determine the current authorized bandwidth of the UP to be adjusted and the UP to be adjusted without determining the UP to be adjusted. The step of increasing the sum of the bandwidths is not greater than the maximum bandwidth of the subscription of the UP to be adjusted.

Step 404: The policy control center sends a response indicating that the UP bandwidth to be adjusted is allowed to be upgraded to the UP to be adjusted, where the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted is not greater than the to-be-adjusted The maximum bandwidth of the UP contract.

This step can be implemented by the following steps 4041 to 4043, including:

4041: The Policy Control Center sends a response to the CP indicating that the UP bandwidth to be adjusted is allowed to be upgraded.

The identifier for indicating that the UP bandwidth to be adjusted is allowed to be carried at least carries the identifier of the UP to be adjusted, and may also carry the incremental bandwidth of the UP to be adjusted.

It should be noted that, if the enhanced bandwidth request sent by the CP to the policy control center for increasing the bandwidth of the UP to be adjusted carries the incremental bandwidth of the UP to be adjusted, the response is used to indicate that the UP bandwidth to be adjusted is allowed to be upgraded. The incremental bandwidth of the UP to be adjusted may not be carried.

If the upgrade bandwidth request sent by the CP to the policy control center for the bandwidth of the UP to be adjusted does not carry the incremental bandwidth of the UP to be adjusted, the response indicating that the UP bandwidth to be adjusted is allowed to be upgraded needs to be carried. Adjusted UP's incremental bandwidth.

4042: The CP forwards the response to the UP to be adjusted to indicate that the UP bandwidth to be adjusted is allowed to be upgraded.

The CP receives the response that is sent by the policy control center to indicate that the UP bandwidth to be adjusted is allowed to be upgraded, and obtains the identifier of the UP to be adjusted from the response for indicating that the UP bandwidth to be adjusted is allowed to be upgraded, according to the UP to be adjusted. The identifier is forwarded to the UP to be adjusted to indicate a response that allows the UP bandwidth to be adjusted to be increased.

It should be noted that the response sent by the policy control center to the CP for indicating that the UP bandwidth to be adjusted is allowed to be carried is carried in a message, and the CP forwards the UP to be adjusted to indicate that the UP bandwidth to be adjusted is allowed to be upgraded. The response is carried in a message, and the protocol types of the two messages may be the same or different.

4043: The UP to be adjusted by the UP receiving CP is used to indicate a response that allows the UP bandwidth to be adjusted to be upgraded.

The UP to be adjusted acquires the incremental bandwidth of the UP to be adjusted, and the current authorized bandwidth of the UP to be adjusted is changed to the sum of the current authorized bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted.

The step of obtaining the incremental bandwidth of the UP to be adjusted for the UP to be adjusted may be:

The UP to be adjusted acquires the incremental bandwidth of the UP to be adjusted from the response for indicating that the UP bandwidth to be adjusted is allowed to be upgraded.

If the response indicating that the UP bandwidth to be adjusted is allowed to be increased does not carry the incremental bandwidth of the UP to be adjusted, the step of the UP to be adjusted to obtain the incremental bandwidth of the UP to be adjusted may be:

The UP to be adjusted acquires the incremental bandwidth of the UP to be adjusted from the subscription information of the UP to be adjusted.

Further, the method for controlling network slice bandwidth provided by the embodiment of the present invention may further include the following steps:

Step 405: The policy control center modifies the current authorized bandwidth of the UP to be adjusted to the sum of the current bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted.

Further, the response of the UP receiving policy control center to be adjusted to indicate that the UP bandwidth to be adjusted is allowed to be upgraded, and the current authorized bandwidth of the UP to be adjusted is also changed to the current bandwidth of the UP to be adjusted and the UP to be adjusted. The sum of the incremental bandwidths.

Example 5

The embodiment of the invention provides a method for controlling the bandwidth of a network slice, which is applied in a policy control center, and is used to reduce the bandwidth of the UP to be adjusted.

When the UP to be adjusted needs to reduce the bandwidth of the UP to be adjusted, the policy control center determines that the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the minimum bandwidth of the UP to be adjusted, and is allowed to be lowered. Adjusted UP bandwidth.

Referring to Figure 5, the method includes:

Step 501: The policy control center receives the reduced bandwidth request sent by the CP, where the reduced bandwidth request is used to reduce the bandwidth of the UP to be adjusted, and the UP to be adjusted is controlled by the CP.

If the number of users of an UP in the UP of the CP or the slice control is decreased, the UP needs to lower the current authorized bandwidth of the UP, determine the UP as the UP to be adjusted, and perform step 501.

Step 501 can be implemented by the following steps 5011-5013, including:

5011: The UP to be adjusted sends a bandwidth reduction request to the CP, where the bandwidth reduction request is used to reduce the bandwidth of the UP to be adjusted, and the UP to be adjusted is controlled by the CP.

When the ratio of the current actual bandwidth of the UP to be adjusted and the current authorized bandwidth of the UP to be adjusted reaches a preset lowering threshold, the UP to be adjusted sends a bandwidth reduction request to the CP that controls the UP to be adjusted, and the reduction is performed. The bandwidth request is used to reduce the bandwidth of the UP to be adjusted.

The preset lowering threshold may be set and changed as needed. In the embodiment of the present invention, the preset lowering threshold is not specifically limited; for example, the preset lowering threshold may be 10% or 20%.

The subscription information of the UP to be adjusted may also include the decremented bandwidth of the UP to be adjusted. The decremented bandwidth of the UP to be adjusted and the incremental bandwidth of the UP to be adjusted may be equal or may not be equal.

Before the UP is sent to the CP to send the bandwidth reduction request, the UP to be adjusted may also determine whether the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the minimum subscription bandwidth of the UP to be adjusted. The adjusted UP determines that the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the minimum subscription bandwidth of the UP to be adjusted, and step 5011 is performed.

If the UP to be adjusted determines that the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is less than the subscription minimum bandwidth of the UP to be adjusted, the process ends.

It should be noted that the reduced bandwidth request carries at least the identifier of the UP to be adjusted, and may also carry the decremented bandwidth of the UP to be adjusted.

The decrementing bandwidth of the UP to be adjusted may be the decrementing bandwidth in the subscription information of the UP to be adjusted; the decrementing bandwidth of the UP to be adjusted may not be the decrementing bandwidth in the subscription information of the UP to be adjusted, and should be set reasonably The decrementing bandwidth ensures that the UP to be adjusted does not frequently adjust the current authorized bandwidth of the UP to be adjusted.

5012: The CP forwards the reduced bandwidth request to the Policy Control Center.

The CP receives the reduced bandwidth request sent by the UP, and forwards the reduced bandwidth request to the policy control center.

It should be noted that the UP to be adjusted to send the reduced bandwidth request to the CP is carried in a message, and the CP forwards the reduced bandwidth request to the policy control center, and the protocol types of the two messages may be the same. Not the same.

5013: The Policy Control Center receives the reduced bandwidth request forwarded by the CP.

Step 502: The policy control center acquires the decremented bandwidth of the UP to be adjusted.

If the reduced bandwidth request carries the decremented bandwidth of the UP to be adjusted, this step may be:

The policy control center obtains the decremented bandwidth of the UP to be adjusted from the reduced bandwidth request.

If the reduced bandwidth request does not carry the decremented bandwidth of the UP to be adjusted, this step may be:

The policy control center obtains the subscription information of the UP to be adjusted. The subscription information of the UP to be adjusted includes the decremented bandwidth of the UP to be adjusted, and the decremented bandwidth of the adjusted UP is obtained from the subscription information of the UP to be adjusted.

Step 503: The policy control center determines that the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the subscription minimum bandwidth of the UP to be adjusted.

The policy control center determines whether the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the minimum subscription bandwidth of the UP to be adjusted, if the policy control center determines the current authorized bandwidth of the UP to be adjusted and the to-be-adjusted The difference between the decremented bandwidths of the UPs is not less than the contracted minimum bandwidth of the UP to be adjusted, and step 504 is performed.

Further, if the policy control center determines that the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is smaller than the subscription minimum bandwidth of the UP to be adjusted, the policy control center sends an indication to the UP to be adjusted for not allowing The response of the UP bandwidth to be adjusted is reduced; the response sent by the UP receiving policy control center to indicate that the UP bandwidth to be adjusted is not allowed to be reduced is sent; the UP receiving policy control center to be adjusted is used to indicate that the lowering is not allowed to be lowered. The response of the adjusted UP bandwidth is not adjusted for the current authorized bandwidth of the adjusted UP.

The step of the policy control center sending a response to the UP to be adjusted indicating that the UP bandwidth to be adjusted is not allowed to be reduced may be:

The policy control center sends a response to the CP for indicating that the UP bandwidth to be adjusted is not allowed to be reduced, and is used to indicate that the response of the UP bandwidth that is not allowed to be adjusted is not allowed to carry the identifier of the UP to be adjusted; The identifier of the UP to be adjusted is obtained from the response indicating that the UP bandwidth to be adjusted is not allowed to be reduced, and the identifier of the UP to be adjusted is adjusted according to the identifier of the UP to be adjusted. The UP forwards the response indicating that the UP bandwidth to be adjusted is not allowed to be lowered.

It should be noted that the policy control center sends a response to the CP for indicating that the UP bandwidth to be adjusted is not allowed to be reduced, and the CP forwards the UP to the UP to be adjusted to indicate that the UP to be adjusted is not allowed to be lowered. The response of the bandwidth is carried in a message, and the protocol types of the two messages may be the same or different.

Further, the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the minimum bandwidth of the UP to be adjusted, because the UP to be adjusted is sent to the CP to reduce the bandwidth request. Therefore, after the step 502 is performed by the policy control center, step 504 may be performed without performing step 504.

Step 504: The Policy Control Center sends a response to the UP to be adjusted to indicate that the UP bandwidth to be adjusted is allowed to be lowered.

This step can be implemented by the following steps 5041 to 5043, including:

5041: The Policy Control Center sends the response to the CP to indicate that the UP bandwidth to be adjusted is allowed to be lowered.

The identifier for indicating that the UP bandwidth to be adjusted is allowed to be reduced, at least carrying the identifier of the UP to be adjusted, and carrying the reduced bandwidth of the UP to be adjusted.

It should be noted that, if the reduced bandwidth request sent by the CP to the policy control center for reducing the bandwidth of the UP to be adjusted carries the decremented bandwidth of the UP to be adjusted, the response is used to indicate that the UP bandwidth to be adjusted is allowed to be lowered. The decrementing bandwidth of the UP to be adjusted may not be carried in the lower bandwidth; if the reduced bandwidth request sent by the CP to the policy control center for reducing the bandwidth of the UP to be adjusted does not carry the decremented bandwidth of the UP to be adjusted, the indication is allowed The response of the UP bandwidth to be adjusted needs to carry the decreasing bandwidth of the UP to be adjusted.

5042: The CP forwards the response to the UP to be adjusted to indicate that the UP bandwidth to be adjusted is allowed to be reduced.

The CP receives the response that is sent by the policy control center to indicate that the UP bandwidth to be adjusted is allowed to be reduced, and obtains the identifier of the UP to be adjusted from the response for indicating that the UP bandwidth to be adjusted is allowed to be lowered, according to the UP to be adjusted. The identifier is forwarded to the UP to be adjusted to indicate a response that allows the UP bandwidth to be adjusted to be lowered.

It should be noted that the policy control center sends a response to the CP indicating that the UP bandwidth to be adjusted is allowed to be reduced in a message, and the CP forwards the UP to be adjusted to indicate that the UP bandwidth to be adjusted is allowed to be lowered. The response is carried in a message, and the protocol types of the two messages may be the same or different.

5043: The UP to be adjusted by the UP receiving CP is used to indicate a response that allows the UP bandwidth to be adjusted to be lowered.

The UP to be adjusted obtains the decremented bandwidth of the UP to be adjusted, and the current authorized bandwidth of the UP to be adjusted is modified to be the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted.

If the response indicating that the UP bandwidth to be adjusted is allowed to be reduced carries the decremented bandwidth of the UP to be adjusted, the step of the UP to be adjusted to obtain the decremented bandwidth of the UP to be adjusted may be:

The UP to be adjusted acquires the decremented bandwidth of the UP to be adjusted from the response indicating that the UP bandwidth to be adjusted is allowed to be lowered.

If the response indicating that the UP bandwidth to be adjusted is allowed to be reduced does not carry the decremented bandwidth of the UP to be adjusted, the step of the UP to be adjusted to obtain the decremented bandwidth of the UP to be adjusted may be:

The subscription information of the UP to be adjusted includes the decremented bandwidth of the UP to be adjusted, and the UP to be adjusted acquires the decremented bandwidth of the UP to be adjusted from the subscription information of the UP to be adjusted.

Step 505: The policy control center modifies the current authorized bandwidth of the UP to be adjusted to the difference between the current bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted.

In the embodiment of the present invention, the policy control center determines that the difference between the current authorized bandwidth of the UP to be adjusted and the decremented bandwidth of the UP to be adjusted is not less than the minimum subscription bandwidth of the UP to be adjusted, and allows the UP to be adjusted to be lowered. The bandwidth of the UP can be allocated to the free bandwidth of the UP to be adjusted to other UPs than the UP to be adjusted, thereby improving the bandwidth utilization of the slice.

Example 6

An embodiment of the present invention provides a method for controlling a network slice bandwidth, which is applied to a CP, and is used to increase a bandwidth of an AN to be adjusted.

When the AN to be adjusted needs to increase the bandwidth of the AN to be adjusted, the policy control center determines that the sum of the current authorized bandwidth of all the ANs controlled by the UP to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is not greater than all the ANs controlled by the UP. The total bandwidth of the subscription allows the bandwidth of the AN to be adjusted to be increased.

It should be noted that if the policy control center determines that the sum of the current authorized bandwidth of all the ANs controlled by the UP to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is greater than the total bandwidth of all the ANs controlled by the UP, and determines the UP bandwidth. The current authorized bandwidth is not greater than the maximum bandwidth of the subscription of the CP, and the bandwidth of the AN to be adjusted is increased by increasing the bandwidth of the UP.

It should be noted that, whether the bandwidth of the AN to be adjusted is directly increased, or the bandwidth of the AN to be adjusted is increased by increasing the bandwidth of the UP, the current authorized bandwidth of the AN to be adjusted and the increment of the AN to be adjusted need to be satisfied. The sum of the bandwidths is not greater than the maximum contracted bandwidth of the AN to be adjusted.

Referring to Figure 6, the method includes:

Step 601: The CP controlling the AN to be adjusted receives the boost bandwidth request sent by the AN to be adjusted to increase the bandwidth of the AN to be adjusted.

In a 5G network, one slice includes at least one CP, each CP of at least one CP controls at least one UP, and each UP of at least one UP includes at least one AN.

The policy control center stores subscription information of each UP controlled by the CP included in the slice, and the policy control center further stores subscription information of each AN included in each UP; the subscription information of any AN included in the slice is at least The incremental bandwidth and the maximum subscription bandwidth of the any AN may also include a decrementing bandwidth; the incremental bandwidth of the any AN may be equal to or different from the degressive bandwidth of the any AN; and the subscription information of the any AN is The initial bandwidth may also be included; the initial bandwidth of the any AN is between the subscription minimum bandwidth and the maximum subscription bandwidth of the any AN; in order to save network resources and improve network utilization, the initial bandwidth of the any AN and the serving The minimum bandwidth of an AN contract is equal.

When any CP included in any slice in the 5G network is initialized, the CP acquires subscription information of each UP controlled by the CP from the policy control center, and obtains each UP of the CP control from the policy control center. Signing information for each AN.

The initial information of the AN is obtained by the AN from the CP, and the subscription information of the AN includes the initial bandwidth of the AN, the maximum bandwidth of the subscription, the minimum bandwidth of the subscription, and the increment. Bandwidth and decrementing bandwidth.

Further, the AN obtains an initial bandwidth of the AN from the subscription information of the AN, and determines an initial bandwidth of the AN as a current authorized bandwidth of the AN.

In the same slice, the initial bandwidth of each AN included in any CP in the slice may be equal or not equal; the maximum bandwidth of each AN included in any CP in the slice may be equal or not equal; The minimum bandwidth for signing of each AN included in any CP in the slice may be equal or not equal; the decrement bandwidth of each AN included in any CP in the slice may be equal or unequal.

It should be noted that the policy control center may configure the initial bandwidth, the contracted maximum bandwidth, the contracted minimum bandwidth, the incremental bandwidth, and/or the decremented bandwidth of each AN according to the service needs of each AN.

The above is the process of initialization of any of the ANs. The following is the process of adjusting the bandwidth of any of the ANs:

As the number of users in any of the ANs increases, the AN needs to increase the current authorized bandwidth of the any AN. The AN that needs to increase the current authorized bandwidth of the AN is called the AN to be adjusted. 601.

When the ratio between the current actual bandwidth of the AN to be adjusted and the current authorized bandwidth of the AN to be adjusted reaches a preset boost threshold, the AN that is to be adjusted sends a PA bandwidth that is to be adjusted to be sent to the CP that controls the AN to be adjusted. The bandwidth request is increased. The CP that controls the AN to be adjusted receives the boost bandwidth request sent by the AN to be adjusted to increase the bandwidth of the AN to be adjusted.

It should be noted that the enhanced bandwidth request carries at least the identifier of the AN to be adjusted, and may also carry the incremental bandwidth of the AN to be adjusted.

The incremental bandwidth of the AN to be adjusted may be the incremental bandwidth in the subscription information of the AN to be adjusted; the incremental bandwidth of the AN to be adjusted may also not be the incremental bandwidth in the subscription information of the AN to be adjusted, and should be set reasonably The incremental bandwidth ensures that the AN to be adjusted does not frequently adjust the current authorized bandwidth of the AN to be adjusted.

Step 602: Control the CP of the AN to be adjusted to obtain the incremental bandwidth of the AN to be adjusted.

If the boost bandwidth request carries the incremental bandwidth of the AN to be adjusted, this step may be:

The CP controlling the AN to be adjusted acquires the incremental bandwidth of the AN to be adjusted from the boost bandwidth request.

If the boost bandwidth request does not carry the incremental bandwidth of the AN to be adjusted, this step may be:

Controlling the CP of the AN to be adjusted to obtain the subscription information of the AN to be adjusted. The subscription information of the AN to be adjusted includes the incremental bandwidth of the AN to be adjusted, and the incremental bandwidth of the adjusted AN is obtained from the subscription information of the AN to be adjusted.

Before the step, the CP that controls the AN to be adjusted acquires the subscription information of each AN that controls the CP of the AN to be adjusted from the policy control center, and stores the subscription information of each AN. Then, the CP that controls the AN to be adjusted acquires the to-be-adjusted. The steps of the AN's signing information can be:

The CP that controls the AN to be adjusted acquires the subscription information of the AN to be adjusted from the correspondence between the identifier and the subscription information according to the identifier of the AN.

Further, the CP that controls the to-be-adjusted AN obtains the initial bandwidth of the AN to be adjusted from the subscription information of the AN to be adjusted, and controls the CP of the AN to be adjusted to notify the policy control center to establish the UP to which the AN to be adjusted belongs and the AN to be adjusted. The transmission network between the two sets the bandwidth of the transmission network to the initial bandwidth of the AN to be adjusted.

The step of the policy control center establishing the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted may be:

The policy control center sends a setup request to the SDN-C (Software Defined Network-Control), where the setup request is used to establish a transport network between the UP to which the AN to be adjusted belongs and the AN to be adjusted, and the establishment is established. The request carries the identifier of the AN to be adjusted and the identifier of the UP to which the AN to be adjusted belongs; the SDN-C receives the setup request sent by the policy control center, and obtains the identifier of the AN to be adjusted and the AN to be adjusted from the setup request The identifier of the UP is established according to the identifier of the AN to be adjusted and the identifier of the UP to which the AN to be adjusted belongs, and establishes a transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted.

Step 603: The CP controlling the AN to be adjusted determines that the sum of the current authorized bandwidth of all the ANs of the UP control to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is not greater than the signing of all the ANs of the UP control to which the AN to be adjusted belongs. Total bandwidth.

The CP controlling the AN to be adjusted determines whether the sum of the current authorized bandwidth of all the ANs of the UP control to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is not greater than the total subscription bandwidth of all the ANs controlled by the UP to which the AN to be adjusted belongs. If the CP controlling the AN to be adjusted determines that the sum of the current authorized bandwidth of all the ANs of the UP control to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is not greater than the total subscription of all the ANs of the UP control to which the AN to be adjusted belongs For bandwidth, go to step 604.

Further, if the CP controlling the AN to be adjusted determines that the sum of the current authorized bandwidth of all the ANs of the UP control to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is greater than the total bandwidth of all the ANs controlled by the UP, step 606 is performed. .

Further, when the bandwidth of the AN to be adjusted is increased, the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted is not greater than the maximum bandwidth of the AN to be adjusted. Therefore, before step 603 is performed. ,Also includes:

The CP controlling the AN to be adjusted determines whether the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted is not greater than the maximum subscription bandwidth of the AN to be adjusted, and if the CP controlling the AN to be adjusted determines the AN to be adjusted when The sum of the pre-authorized bandwidth and the incremental bandwidth of the AN to be adjusted is not greater than the maximum contracted bandwidth of the AN to be adjusted, and step 603 is performed.

If the CP controlling the AN to be adjusted determines that the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted is greater than the subscription maximum bandwidth of the AN to be adjusted, sending to the AN to be adjusted is used to indicate that the upgrade is not allowed to be adjusted. Response of the AN bandwidth; the AN to be adjusted receives a response sent by the CP that controls the AN to be adjusted to indicate that the AN bandwidth to be adjusted is not allowed to be upgraded, and does not adjust the current authorized bandwidth of the AN to be adjusted.

It should be noted that the AN to be adjusted may also determine the current authorized bandwidth of the AN to be adjusted and the to-be-adjusted before the AN to be adjusted is sent to the CP that controls the AN to be adjusted. Whether the sum of the incremental bandwidths of the ANs is greater than the subscription maximum bandwidth of the AN to be adjusted, if the AN to be adjusted determines that the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted is not greater than the subscription of the AN to be adjusted The maximum bandwidth is sent to the CP controlling the AN to be adjusted to increase the bandwidth request for the AN bandwidth to be adjusted.

Step 604: The CP that controls the to-be-adjusted AN sends a response to the AN to be adjusted to indicate that the AN bandwidth to be adjusted is allowed to be upgraded, where the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted is not greater than The maximum bandwidth of the contract of the AN to be adjusted.

The identifier for indicating that the AN bandwidth to be adjusted is allowed to be enhanced carries at least the identifier of the AN to be adjusted, and may also carry the incremental bandwidth of the AN to be adjusted.

It is to be noted that, if the to-be-adjusted AN carries the incremental bandwidth of the AN to be adjusted, and the enhanced bandwidth request for the bandwidth of the AN to be adjusted is used to transmit the bandwidth of the AN to be adjusted, the The response of the adjusted AN bandwidth may not carry the incremental bandwidth of the AN to be adjusted.

If the to-be-adjusted AN does not carry the incremental bandwidth of the AN to be adjusted in the boost bandwidth request for increasing the bandwidth of the AN to be adjusted, the AN is used to indicate that the AN bandwidth to be adjusted is allowed to be upgraded. The response needs to carry the incremental bandwidth of the AN to be adjusted.

The AN to be adjusted receives the response of the AN to be adjusted, and the current authorized bandwidth of the AN to be adjusted is modified to the current authorized bandwidth of the AN to be adjusted and the AN to be adjusted. The sum of the incremental bandwidths.

Step 605: The CP controlling the AN to be adjusted modifies the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted to the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted.

The CP controlling the AN to be adjusted modifies the current authorized bandwidth of the AN to be adjusted to the sum of the current bandwidth of the AN to be adjusted and the incremental bandwidth of the AN. The notification policy control center modifies the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted to the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted.

The step of modifying, by the policy control center, the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted is the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted may be:

The policy control center sends a modification request to the SDN-C, where the modification request is used to modify the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted, and the modification request carries the identifier and the to-be of the AN to be adjusted. The identifier of the UP to which the adjusted AN belongs; the SDN-C receives the modification request sent by the policy control center, and according to the identifier of the AN to be adjusted and the identifier of the UP to which the AN to be adjusted belongs, the UP to which the AN to be adjusted belongs The bandwidth of the transmission network between the ANs to be adjusted is modified to be the sum of the current authorized bandwidth of the AN to be adjusted and the incremental bandwidth of the AN to be adjusted.

Step 606: The CP controlling the AN to be adjusted determines that the sum of the current authorized bandwidth of all the ANs of the UP control to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is greater than the total bandwidth of all the ANs controlled by the UP, and determines the UP bandwidth. when The pre-authorized bandwidth is not greater than the maximum subscription bandwidth of the UP to which the AN to be adjusted belongs.

Further, if it is determined that the sum of the current authorized bandwidth of all the ANs controlled by the UP to which the AN to be adjusted belongs and the incremental bandwidth of the AN to be adjusted is greater than the total signed bandwidth of all the ANs controlled by the UP, and determining that the current authorized bandwidth of the UP is greater than The subscribed maximum bandwidth of the UP to which the adjusted AN belongs, and a response for indicating that the bandwidth of the AN to be adjusted is not allowed to be raised is sent to the AN to be adjusted.

Step 607: The CP that controls the AN to be adjusted sends a boost bandwidth request for raising the UP bandwidth to which the AN to be adjusted belongs to the policy control center.

The policy control center receives the boost bandwidth request for the UP bandwidth to which the AN to be adjusted belongs, and controls the bandwidth of the UP to which the AN to be adjusted belongs according to the method in the foregoing Embodiment 3.

If the policy control center determines that the UP bandwidth to which the AN to be adjusted belongs can be raised, the policy control center sends a response to the CP that controls the AN to be adjusted to indicate that the UP bandwidth to which the AN to be adjusted belongs is not allowed to be upgraded, and then the control is to be adjusted. The CP of the AN sends a response to the AN to be adjusted indicating that the AN bandwidth to be adjusted is not allowed to be boosted.

If the policy control center determines that the UP bandwidth to which the to-be-tuned AN belongs, the policy control center sends a response to the CP that controls the AN to be adjusted to indicate that the UP bandwidth to which the AN to be adjusted belongs is allowed to be sent, and step 608 is performed.

Step 608: Control the response of the UP bandwidth of the to-be-adjusted AN to be sent by the CP receiving policy control center of the to-be-adjusted AN, and modify the current authorized bandwidth of the UP bandwidth to which the AN to be adjusted belongs to the AN to be adjusted.

Example 7

The embodiment of the invention provides a method for controlling the bandwidth of a network slice, which is applied in a CP, and is used to reduce the bandwidth of the AN to be adjusted.

When the AN to be adjusted needs to reduce the bandwidth of the AN to be adjusted, the policy control center determines that the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted is not less than the minimum subscription bandwidth of the AN to be adjusted, and is allowed to be lowered. The bandwidth of the AN to be adjusted.

Referring to Figure 7, the method includes:

Step 701: The CP controlling the AN to be adjusted receives the reduced bandwidth request sent by the AN to be adjusted for reducing the bandwidth of the AN to be adjusted.

If the number of users of an AN in the AN controlled by the CP decreases, the AN needs to lower the current authorized bandwidth of the AN, determine the AN as the AN to be adjusted, and perform step 701.

When the ratio between the current actual bandwidth of the AN to be adjusted and the current authorized bandwidth of the AN to be adjusted reaches a preset lowering threshold, the AN that is to be adjusted sends a lower bandwidth of the AN to be adjusted to the CP that controls the AN to be adjusted. The bandwidth request is reduced; the CP controlling the AN to be adjusted receives the reduced bandwidth request sent by the AN to be adjusted for reducing the bandwidth of the AN to be adjusted.

The preset lowering threshold may be set and changed as needed. In the embodiment of the present invention, the preset lowering threshold is not Specifically defined; for example, the preset lowering threshold may be 10% or 20%.

It should be noted that the reduced bandwidth request carries at least the identifier of the AN to be adjusted, and may also carry the decreasing bandwidth of the AN to be adjusted.

The decrementing bandwidth of the AN to be adjusted may be the decrementing bandwidth in the subscription information of the AN to be adjusted; the decrementing bandwidth of the AN to be adjusted may not be the degressive bandwidth in the subscription information of the AN to be adjusted, and should be set reasonably Decreasing the bandwidth, ensuring that the AN to be adjusted does not frequently adjust the current authorized bandwidth of the AN to be adjusted.

Step 702: Control the CP of the AN to be adjusted to obtain the decreasing bandwidth of the AN to be adjusted.

If the boost bandwidth request carries the decrementing bandwidth of the AN to be adjusted, this step may be:

The CP controlling the AN to be adjusted acquires the decreasing bandwidth of the AN to be adjusted from the boost bandwidth request.

If the boost bandwidth request does not carry the degressive bandwidth of the AN to be adjusted, this step may be:

The CP of the AN to be adjusted acquires the subscription information of the AN to be adjusted. The subscription information of the AN to be adjusted includes the decremented bandwidth of the AN to be adjusted, and the decremented bandwidth of the adjusted AN is obtained from the subscription information of the AN to be adjusted.

Step 703: The CP controlling the AN to be adjusted determines that the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted is not less than the subscription minimum bandwidth of the AN to be adjusted.

The CP that controls the AN to be adjusted determines whether the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted is not less than the subscription minimum bandwidth of the AN to be adjusted, and if the CP controlling the AN to be adjusted determines the AN to be adjusted The difference between the current authorized bandwidth and the decremented bandwidth of the AN to be adjusted is not less than the minimum contracted bandwidth of the AN to be adjusted, and step 704 is performed.

If the CP controlling the AN to be adjusted determines that the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted is smaller than the subscription minimum bandwidth of the AN to be adjusted, the CP controlling the AN to be adjusted is sent to the AN to be adjusted for sending The indication indicates that the response of the AN bandwidth to be adjusted is not allowed to be reduced; the AN to be adjusted receives the response sent by the CP that controls the AN to be adjusted to indicate that the bandwidth of the AN to be adjusted is not allowed to be reduced, and the current authorized bandwidth of the AN to be adjusted is not adjusted. .

Step 704: The CP controlling the AN to be adjusted sends a response indicating that the AN bandwidth to be adjusted is allowed to be lowered to the AN to be adjusted.

The identifier for indicating that the AN bandwidth to be adjusted is allowed to be reduced carries at least the identifier of the AN to be adjusted, and may also carry the decreasing bandwidth of the AN to be adjusted.

It should be noted that, if the to-be-adjusted AN carries the decrementing bandwidth of the AN to be adjusted, and the reduced bandwidth request for reducing the bandwidth of the AN to be adjusted is sent to the CP of the to-be-adjusted AN, the indication is allowed to be lowered. The adjusted bandwidth of the AN bandwidth may not carry the decrementing bandwidth of the AN to be adjusted; if the AN to be adjusted does not carry the to-be-tuned request in the reduced bandwidth request for reducing the bandwidth of the AN to be adjusted sent by the CP controlling the AN to be adjusted The decrementing bandwidth of the AN is used to indicate that the declining bandwidth of the AN to be adjusted needs to be carried in the response that allows the AN bandwidth to be adjusted to be reduced.

The AN to be adjusted receives the response of the AN to be adjusted, and the decremented bandwidth of the AN to be adjusted is obtained, and the current authorized bandwidth of the AN to be adjusted is modified to be adjusted. The difference between the current authorized bandwidth of the AN and the decreasing bandwidth of the AN to be adjusted.

If the response for the AN to be adjusted is carried in the response of the AN to be adjusted, the step of obtaining the decremented bandwidth of the AN to be adjusted may be:

The AN to be adjusted acquires the decremented bandwidth of the AN to be adjusted from the response indicating that the AN bandwidth to be adjusted is allowed to be reduced.

If the response indicating that the AN bandwidth to be adjusted is allowed to be reduced does not carry the decreasing bandwidth of the AN to be adjusted, then The step of the AN to be adjusted to obtain the decremented bandwidth of the AN to be adjusted may be:

The contract information of the AN to be adjusted includes the decrementing bandwidth of the AN to be adjusted, and the AN to be adjusted acquires the decrementing bandwidth of the AN to be adjusted from the subscription information of the AN to be adjusted.

Step 705: The CP controlling the AN to be adjusted modifies the current authorized bandwidth of the AN to be adjusted to the difference between the current bandwidth of the AN to be adjusted and the decreasing bandwidth of the AN to be adjusted.

Controlling the CP of the to-be-adjusted AN The policy control center modifies the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted to the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted. .

The step of the policy control center changing the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted to the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted may be:

The policy control center sends a modification request to the SDN-C, where the modification request is used to modify the bandwidth of the transmission network between the UP to which the AN to be adjusted belongs and the AN to be adjusted, and the modification request carries the identifier and the to-be of the AN to be adjusted. The identifier of the UP to which the adjusted AN belongs; the SDN-C receives the modification request sent by the policy control center, and according to the identifier of the AN to be adjusted and the identifier of the UP to which the AN to be adjusted belongs, the UP to which the AN to be adjusted belongs The bandwidth of the transmission network between the ANs to be adjusted is modified to be the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted.

In the embodiment of the present invention, when the CP controlling the AN to be adjusted determines that the difference between the current authorized bandwidth of the AN to be adjusted and the decremented bandwidth of the AN to be adjusted is not less than the minimum contracted bandwidth of the AN to be adjusted, the AN to be adjusted is allowed to decrease.
