Description

Bandwidth allocation method and system

technical field

The present invention relates to the technical field of communication, and more specifically, relates to a bandwidth allocation method and system.

Background technique

As a channel provider for network communications, operators need to manage operations with service quality as their core competitiveness. In the field of network communication, an important criterion for judging the quality of service is the network bandwidth that users can enjoy.

The bandwidth (Speed) is obtained by multiplying the number of radio resource units (RE) obtained by the user and the scheduling efficiency (efficiency) of the user, that is, Speed=RE_Number*efficiency. In a wireless network system, wireless resources are limited. When the wireless resources are constant, the scheduling efficiency (efficiency) directly determines the actual bandwidth (Speed) that users can obtain, and the scheduling efficiency (efficiency) is directly determined by the user's signal quality. Among users of network communication, in order to enjoy higher bandwidth, some users will sign bandwidth guarantee agreements with operators, thus becoming bandwidth guarantee users. Once a bandwidth guarantee user becomes a user, the operator needs to guarantee the bandwidth quality that the bandwidth guarantee user can actually enjoy according to the bandwidth agreement.

In order to ensure that the actual bandwidth of the bandwidth guarantee user can reach the agreed bandwidth, a bandwidth allocation method is usually adopted in the prior art. After the user accesses the wireless system, this method first judges whether the current user is a bandwidth guarantee user, and gives priority to serving the bandwidth Protect users. When allocating wireless resources to bandwidth guarantee users, wireless resources will be allocated according to the user's protocol bandwidth, signal quality and data transmission requirements. If the current bandwidth guarantee user's signal quality is relatively poor, more or even all wireless resources will be allocated Resources are allocated to the current bandwidth guarantee users so that their bandwidth can reach or approach the agreed bandwidth.

To sum up, it can be seen that the method of allocating bandwidth in the prior art concentrates all wireless resources and preferentially serves individual bandwidth guarantee users. When the signal quality of the current user is poor, the wireless resource consumption of this method is huge, and it may still fail to Guarantee the user's protocol bandwidth; in this case, fixed wireless resources can serve very few users, and most users cannot be allocated wireless resources in time, so the use of wireless resources is uneconomical.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Fig. 1 is a flow chart of the bandwidth allocation method disclosed in the embodiment of the present invention, as shown in Fig. 1, the method may include:

Step 101: Determine whether there is a user to be scheduled that meets the preset condition; if yes, go to step 102.

The specific steps of step 101 may be: judging whether there is a bandwidth guarantee user who has signed a bandwidth guarantee agreement with the operator and has reserved wireless resources when accessing the wireless network. If there is a bandwidth guaranteed user to be scheduled in the current scheduling cycle, and the system has reserved wireless resources for the bandwidth guaranteed user when accessing the network, then in the current scheduling cycle, the bandwidth guaranteed user can perform subsequent Steps involved in allocating bandwidth. Of course, there may be multiple users to be scheduled who meet the above preset conditions in a scheduling cycle. Since all users who meet the conditions and conditions have reserved resources, multiple users to be scheduled who meet the preset conditions can be scheduled at the same time. , or perform subsequent processes sequentially according to the time when it sends out a data transmission or download request. In the current scheduling period, there is no user to be scheduled that meets the preset condition, and the following steps 102-103 are not performed.

Wherein, in a schematic example, the specific process for the user to be scheduled who meets the preset conditions to reserve wireless resources when accessing the wireless network can be referred to FIG. 2 . The resource flow chart, as shown in Figure 2, may include:

Step 201: Calculate the amount of wireless resources required by the bandwidth guarantee user according to the protocol content corresponding to the bandwidth guarantee user.

Wherein, the content of the agreement corresponding to the bandwidth guarantee user may include but not limited to the identification information of the user, the protocol bandwidth and the protocol signal quality threshold in the bandwidth guarantee agreement signed between the user and the operator, since the bandwidth of the user is allocated by The amount of wireless resources and the scheduling efficiency of the crosstalk are obtained, and the scheduling efficiency is determined by the user's signal quality. Therefore, when the protocol bandwidth and the protocol signal quality threshold are determined, the bandwidth can be calculated to ensure the user's needs, or should be allocated to the bandwidth Guarantee the amount of wireless resources for users.

Step 202: Determine whether the current remaining amount of wireless resources is greater than or equal to the amount of wireless resources; if yes, go to step 203.

Only when the current remaining amount of wireless resources is greater than or equal to the amount of wireless resources required by the bandwidth guaranteed user calculated in step 201, can the wireless resources matching the amount of wireless resources be reserved for the bandwidth guaranteed user. When the remaining amount of the current wireless resource is less than the amount of the wireless resource, the wireless resource cannot be reserved for the bandwidth guarantee user to which it belongs.

Step 203: Reserve wireless resources for the bandwidth guaranteed users according to the amount of wireless resources.

In actual situations, it may also happen that the current remaining amount of wireless resources is smaller than the amount of wireless resources calculated in step 201, and in this case, wireless resources cannot be reserved for the bandwidth guaranteed users. In order to distinguish whether the bandwidth guarantee user has reserved wireless resources, please refer to the flow chart in Figure 3, which is another flow chart for reserving wireless resources disclosed in the embodiment of the present invention, as shown in Figure 3, in other embodiments , in addition to steps 201-203, may also include:

Step 204: Mark the bandwidth guaranteed user as a resource reservation state, and add it to the bandwidth guaranteed user scheduling table.

Step 205: When the current remaining amount of wireless resources is less than the amount of wireless resources, mark the bandwidth guaranteed user as resource unreserved state, and add the bandwidth guaranteed user scheduling table.

The marks in steps 204 and 205 can use different data marks, for example, "0" is used to indicate that the resource is not reserved, and "1" is used to indicate that the resource has been reserved; letter marks or other marking methods can also be used to mark and distinguish bandwidth guarantees The reservation status of the user's radio resources.

In a scheduling period, there may be cases where users access or release wireless resources. Therefore, the current remaining wireless resources may change at any time. Therefore, when each bandwidth guarantees that users access the wireless network , it is necessary to judge whether the remaining amount of the current wireless resource can meet the requirement of the resource reserved by the bandwidth guarantee user. When wireless resources are released in the wireless network, the remaining wireless resources after release may be reserved for bandwidth guarantee users without reserved wireless resources.

After step 101, go to step 102.

Step 102: Determine the amount of wireless resources that should be allocated to the user to be scheduled who meets the preset condition according to the agreement content corresponding to the user to be scheduled who meets the preset condition.

In a schematic example, the specific process of step 102 can be referred to FIG. 4. FIG. 4 is a flow chart of computing bandwidth to guarantee wireless resources required by users disclosed in an embodiment of the present invention. As shown in FIG. 4, it may include:

Step 401: Obtain the protocol signal quality threshold and protocol bandwidth in the protocol content corresponding to the scheduled user meeting the preset condition.

Since the size of the user's bandwidth is obtained from the amount of wireless resources allocated to it and the scheduling efficiency, and the scheduling efficiency is determined by the user's signal quality, the bandwidth can be calculated when the protocol bandwidth and the protocol signal quality threshold are determined. Guaranteed user needs, or the amount of wireless resources that should be allocated to bandwidth guaranteed users. Therefore, step 401 first acquires the protocol signal quality threshold and protocol bandwidth in the protocol content corresponding to the user to be scheduled that meets the preset condition.

Step 402: Calculate the amount of wireless resources that should be allocated to the bandwidth guaranteed user according to the protocol signal quality threshold and the protocol bandwidth.

After step 102, go to step 103.

Step 103: Allocate corresponding wireless resources to the users to be scheduled who meet preset conditions according to the amount of wireless resources.

In step 101, when it is judged that the scheduling cycle includes a bandwidth guaranteed user, and the system has reserved wireless resources for the bandwidth guaranteed user when accessing the wireless network, step 102 calculates that the bandwidth guaranteed user should be allocated to the For the amount of wireless resources of the bandwidth guaranteed user, step 103 allocates corresponding wireless resources for the bandwidth guaranteed user according to the amount of wireless resources calculated in step 102 .

In other embodiments, when there is no user to be scheduled meeting the preset condition in the current scheduling period, a step of allocating wireless resources to the user to be scheduled according to a preset scheduling policy may also be included. Wherein, the preset scheduling policy may include but not limited to at least one of a proportional fairness policy and an efficiency priority policy.

In this embodiment, when the bandwidth allocation method allocates bandwidth to the bandwidth guarantee user, it will calculate the amount of wireless resources that should be allocated to the bandwidth guarantee user according to the content of the agreement signed between the bandwidth guarantee user and the operator, and according to The calculated amount of wireless resources allocates a fixed bandwidth to the bandwidth guarantee user. The method allocates bandwidth to the bandwidth guarantee user, only allocates a fixed amount of wireless resources to the bandwidth guarantee user based on the content of the agreement between the bandwidth guarantee user and the operator, and does not change the wireless network because of the signal quality of the bandwidth guarantee user. resource allocation, thereby avoiding the situation that most or even the front wireless resources are allocated to the bandwidth guaranteed users when the signal quality of the bandwidth guaranteed users is very poor, and it is possible to ensure that all wireless resources are allocated in a certain scheduling strategy Under the premise of fair allocation to multiple users, the utilization of bandwidth resources is reasonable and economical.

On the basis of the above-mentioned embodiments, there is another implementation mode of the present invention, which can be referred to FIG. 5. FIG. 5 is a flow chart of another bandwidth allocation method disclosed in the embodiment of the present invention. As shown in FIG. 5, the method may include :

Step 501: Determine whether there is a user to be scheduled that meets the preset condition; if yes, go to step 502.

Wherein, the user to be scheduled who meets the preset condition may be a bandwidth guaranteed user, and the system has reserved wireless resources for the bandwidth guaranteed user when accessing the wireless network.

Step 502: According to the protocol signal quality threshold and protocol bandwidth in the protocol content corresponding to the user to be scheduled who meets the preset condition, determine the amount of wireless resources that should be allocated to the user to be scheduled who meets the preset condition.

Since the size of the user's bandwidth is obtained from the amount of wireless resources allocated to it and the scheduling efficiency, and the scheduling efficiency is determined by the user's signal quality, the bandwidth can be calculated when the protocol bandwidth and the protocol signal quality threshold are determined. Guaranteed user needs, or the amount of wireless resources that should be allocated to bandwidth guaranteed users.

Step 503: Allocate corresponding wireless resources to the users to be scheduled who meet preset conditions according to the amount of wireless resources.

Step 504: Determine whether the signal quality of the user to be scheduled meeting the preset condition is lower than the signal quality threshold; if yes, go to step 506; if not, go to step 505.

Because the amount of wireless resources allocated to a bandwidth guarantee user is calculated according to the protocol bandwidth and protocol signal quality threshold in the bandwidth guarantee agreement signed between the bandwidth guarantee user and the operator, and is a fixed value, and when the bandwidth guarantee user When the signal quality of the bandwidth changes, correspondingly, the bandwidth actually available to the bandwidth guarantee user will also change with the change of the signal quality. If the signal quality of the bandwidth guarantee user is good, the obtained actual bandwidth is relatively larger; if the signal quality is not good, the obtained actual bandwidth is relatively small.

Step 505: Sending first indication information to the terminal of the bandwidth guarantee user; the first indication information is used to indicate that the current state is a bandwidth guarantee state.

When the signal quality of the bandwidth guaranteed user is greater than or equal to the signal quality threshold of the agreement, the actually available bandwidth of the bandwidth guaranteed user can reach or even exceed the agreed bandwidth with the operator. The terminal of the bandwidth guaranteed user may be notified through the corresponding control circuit that the current state is a bandwidth guaranteed state, that is, the current bandwidth can reach or exceed the bandwidth agreed between the bandwidth guaranteed user and the operator.

Step 506: Sending second indication information to the terminal of the bandwidth guaranteed user; the second indication information is used to indicate that the current state is a state of unguaranteed bandwidth.

When the signal quality of the bandwidth guaranteed user is lower than the agreed signal quality threshold, the bandwidth actually available to the bandwidth guaranteed user cannot reach the agreed bandwidth with the operator. The terminal of the bandwidth-guaranteed user may be notified through the corresponding control circuit that the current state is a state of unguaranteed bandwidth, that is, the current bandwidth cannot reach the agreed bandwidth between the bandwidth-guaranteed user and the operator.

In this implementation, whether the bandwidth can reach the protocol bandwidth is determined by the signal quality of the bandwidth guaranteed user. When the signal quality of the bandwidth guaranteed user can reach the protocol signal quality threshold, the bandwidth is guaranteed; When the signal quality threshold is exceeded, the bandwidth cannot be guaranteed. The corresponding bandwidth status and the corresponding signal quality of the bandwidth guaranteed user can be sent to the terminal of the bandwidth guaranteed user at any time, so that the bandwidth guaranteed user can realize clear consumption.

In this embodiment, when the bandwidth allocation method allocates bandwidth to the bandwidth guarantee user, it will calculate the amount of wireless resources that should be allocated to the bandwidth guarantee user according to the content of the agreement signed between the bandwidth guarantee user and the operator, and according to The calculated amount of wireless resources allocates a fixed bandwidth to the bandwidth guarantee user. The method does not change the allocation amount of wireless resources due to the quality of the signal quality of the bandwidth-guaranteed user, thereby avoiding that when the signal quality of the bandwidth-guaranteed user is very poor, allocating most or even the front wireless resources to the In the case of bandwidth guarantee users, it can ensure that all wireless resources are allocated to multiple users fairly under the premise of a certain scheduling strategy, and the utilization of bandwidth resources is reasonable and economical. Moreover, the method can instruct and notify the bandwidth guarantee user's signal quality and bandwidth status in real time, enabling the bandwidth guarantee user to know the bandwidth status at any time, and realizing clear consumption.

Fig. 6 is a schematic diagram of the control and admission process disclosed in the embodiment of the invention. Referring to Fig. 6, the admission control process reserves wireless resources for the bandwidth-guaranteed users according to the protocol signal quality threshold when the bandwidth-guaranteed users access the wireless network; when the wireless resources are insufficient , set the bandwidth guarantee user to the resource unreserved state. The admission control process releases the reserved wireless resource when the bandwidth guaranteed user releases, and un-allocates the wireless resource to the bandwidth guaranteed user who has not reserved wireless resources. The admission control process guarantees the bandwidth to ensure that users can access the wireless network and obtain reserved wireless resources when the wireless resources are sufficient; when the wireless resources are insufficient, they can also access the wireless network, but cannot reserve resources.

The admission control process may include:

Step 619: Set the bandwidth guarantee user to resource reservation status.

Step 620: The release is successful.

FIG. 7 is a schematic diagram of a scheduling process disclosed in an embodiment of the present invention. Referring to FIG. 6, when the signal quality of a bandwidth-guaranteed user is higher than or equal to the protocol signal quality threshold, the reserved wireless resources are used to satisfy the bandwidth of the bandwidth-guaranteed user. When the bandwidth can be guaranteed and may exceed the protocol bandwidth; when the signal quality of the bandwidth-guaranteed user is lower than the signal quality threshold of the protocol bandwidth, the reserved wireless resources are used to support the user's bandwidth demand, and the bandwidth cannot be guaranteed at this time.
