It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The bandwidth allocation method provided in the embodiment of the present application may be applied to an implementation environment shown in fig. 1, where as shown in fig. 1, the implementation environment may include a user terminal 101, a base station 102, and an MEC (Mobile Edge Computing) server 103. The base station 102 may communicate with the user terminal 101 through a wireless network, and the base station 102 may communicate with the MEC server 103 through a wired network. Both the base station 102 and the MEC server 103 may communicate with core network equipment (not shown in fig. 1).
The user terminal 101 may be a personal computer, a notebook computer, a media player, a smart television, a smart phone, a tablet computer, a portable wearable device, and the like, and the type of the user terminal 101 is not particularly limited in this embodiment of the application.

The bandwidth allocation method, device, computer equipment and computer-readable storage medium provided by the embodiment of the application aim to solve the technical problem that the data transmission efficiency of a service session is poor in the process of accessing an application by a user terminal due to the fact that the bandwidth of an air interface side is managed by the traditional technology. The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In one embodiment, as shown in fig. 2, a bandwidth allocation method is provided, which is described by taking the method as an example applied to the MEC server shown in fig. 1, and the method includes steps 201, 202, and 203:
step 201, the MEC server receives service bandwidth application information.
With the rapid development of communication technology and the popularization of intelligent terminals, third-party content providers develop more and more applications for user terminal installation for users to use. When accessing a target application, a user terminal firstly establishes communication connection with a server deploying the target application, the target application may be any third-party application, and the target application may be deployed in an MEC server or may also be deployed in a local cloud server.
And after the target terminal establishes communication connection with the server deploying the target application, the server deploying the target application sends service bandwidth application information to the MEC server. Taking the example that the target application is deployed in the MEC server, the sending process is the information sending among the internal communication modules of the MEC server; taking the example that the target application is deployed in the local cloud server, the sending process is that the local cloud server sends the service bandwidth application information to the MEC server, and the specific deployment position of the target application is not specifically limited in the embodiment of the present application.
And after the server deploying the target application sends the service bandwidth application information to the MEC server, the MEC server receives the service bandwidth application information. In this embodiment of the application, the service bandwidth application information is used for the target application to apply for the network bandwidth and the air interface bandwidth of the target service session for the user terminal, where the target service session is a session of a service provided by the target application to the user terminal, that is, to apply for the network bandwidth and the air interface bandwidth required by the target application to provide the service to the user terminal. Based on the applied air interface bandwidth, the user terminal and the base station can perform data transmission of the target service session, and based on the applied network bandwidth, the base station and the MEC server can perform data transmission of the target service session, so that the target application can provide service for the user terminal.
In the embodiment of the present application, the service bandwidth application information includes an application bandwidth, a terminal identifier of the user terminal, and a service IP address of a server deploying the target application, where the application bandwidth is a bandwidth applied by the target application to the MEC server for the user terminal for the target service session.
Step 202, the MEC server determines a target service session from each service session to be allocated with network bandwidth according to the terminal identifier and the service IP address, and allocates network bandwidth to the user terminal according to the size relationship between the application bandwidth and the remaining bandwidth.
After receiving the service bandwidth application information, the MEC server determines a target service session from each service session of the network bandwidth to be allocated according to the terminal identification and the service IP address. In a possible implementation manner, the MEC server may search a terminal IP address of the user terminal according to the terminal identifier, and then determine a target service session from each service session to be allocated with the network bandwidth according to the service IP address and the terminal IP address. In another possible implementation, the MEC server may further use the terminal identifier and the service IP address as session identifiers, and search for a service session corresponding to the session identifier, that is, a target service session.
In the embodiment of the application, each time the MEC server allocates the network bandwidth, the remaining bandwidth is updated once, and the latest remaining bandwidth is stored. And the MEC server distributes network bandwidth for the user terminal according to the size relation between the application bandwidth in the service bandwidth application information and the latest residual bandwidth.
In a possible implementation manner, if the requested bandwidth is less than or equal to the remaining bandwidth, the MEC server satisfies the requested bandwidth requested in the service bandwidth request information, and allocates a network bandwidth with the same size as the requested bandwidth to the user terminal.
In another possible implementation, if the requested bandwidth is greater than the remaining bandwidth, the MEC server may allocate the remaining bandwidth to the user terminal entirely. Or, the MEC server may also allocate network bandwidth in combination with a user level corresponding to the user terminal, where the user level may be an account level corresponding to the target application for the user, such as an ordinary user, a VIP user, or a super VIP user, and so on; if the user level corresponding to the user terminal is higher (such as a VIP user), the MEC server may perform bandwidth contraction on the terminal to which the network bandwidth has been allocated and the user level is lower (such as a general user), and allocate the bandwidth released after the bandwidth contraction and the remaining bandwidth to the user terminal, so as to better satisfy the application bandwidth requested in the service bandwidth application information under the condition that the application bandwidth is greater than the remaining bandwidth.
Thereby, the MEC server allocates network bandwidth to the user terminal.
Step 203, the MEC server configures air interface bandwidth application information according to the service bandwidth application information, and sends the air interface bandwidth application information to the base station, so that the base station allocates an air interface bandwidth to the user terminal according to the air interface bandwidth application information.
In this embodiment, the MEC server configures air interface bandwidth application information according to the service bandwidth application information, where the air interface bandwidth application information may include an air interface identifier and an application bandwidth corresponding to the user terminal. After receiving the air interface bandwidth application information, the base station determines a target service session according to an air interface identifier, calculates the number of bits to be scheduled of the target service session in a Transmission Time Interval (TTI), and performs scheduling by synthesizing the air interface wireless environment quality, the number of scheduling bits, and the like, to allocate an air interface bandwidth to the user terminal.
The method includes the steps of receiving service bandwidth application information, wherein the service bandwidth application information is used for a target application to apply a network bandwidth and an air interface bandwidth aiming at a target service session for a user terminal, the service bandwidth application information comprises an application bandwidth, a terminal identifier of the user terminal and a service IP address of a server for deploying the target application, then determining the target service session from each service session of the network bandwidth to be allocated according to the terminal identifier and the service IP address, allocating the network bandwidth for the user terminal according to the size relation between the application bandwidth and the residual bandwidth, configuring air interface bandwidth application information according to the service bandwidth application information, and sending the air interface bandwidth application information to a base station, so that the base station allocates the air interface bandwidth to the user terminal according to the air interface bandwidth application information. Thus, after receiving the service bandwidth application information, the embodiment of the application performs network side bandwidth management and air interface side bandwidth management simultaneously, and allocates a network bandwidth and an air interface bandwidth to the user terminal, thereby avoiding the problem that in the conventional technology, the efficiency of data transmission of a service session is poor in the process of accessing an application by the user terminal due to the fact that the air interface bandwidth and the network bandwidth are not matched because only the air interface bandwidth is managed. According to the method and the device, after the service bandwidth application information is received, network side bandwidth management and air interface side bandwidth management are simultaneously carried out, so that the matching degree of the network bandwidth and the air interface bandwidth of the user terminal can be improved, the data transmission efficiency of the target service session in the process that the user terminal accesses the target application is improved, and the application access experience of the user is improved.
In one embodiment, based on the above-described embodiment shown in fig. 2, referring to fig. 3, this embodiment relates to a process of how the MEC server determines a target service session from service sessions to which network bandwidth is to be allocated according to a terminal identifier and a service IP address. As shown in fig. 3, the process includes steps 301 and 302:
step 301, the MEC server searches for the terminal IP address of the user terminal corresponding to the terminal identifier according to the terminal identifier.
In the embodiment of the application, the MEC server may receive, through the base station, the attribute information of the user terminal sent by the user terminal, and store the received attribute information. The attribute information includes a terminal identifier of the user terminal, and the attribute information further includes at least one of a terminal IP address of the user terminal and an air interface identifier of the user terminal.
In one possible embodiment, the attribute information is collected by the user terminal. For example, the user terminal may periodically collect attribute information of the user terminal, and each time attribute information is collected, the user terminal compares the currently collected attribute information with the attribute information collected last time, if the currently collected attribute information does not change, the user terminal discards the currently collected attribute information, and if the currently collected attribute information changes, the user terminal sends the currently collected attribute information to the MEC server through the base station, and after the MEC server receives the attribute information of the user terminal, the MEC server stores the attribute information as the latest attribute information of the user terminal.
In another possible implementation, the attribute information is acquired by a terminal information acquisition module connected to a communication module of the user terminal under the control of the user terminal. The terminal information acquisition module can be an independent hardware module, the communication module can be a 5G CPE or a 5G module, and the terminal information acquisition module is connected with the communication module. The process of the user terminal controlling the terminal information acquisition module to acquire the attribute information is similar to the process of the user terminal periodically acquiring the attribute information of the user terminal, and is not repeated here.
In the embodiment of the present application, the terminal identifier may be an MSISDN mobile subscriber number or an IMSI international mobile subscriber identity of the user terminal. The attribute information also comprises a terminal IP address of the user terminal, and the MEC server searches the terminal IP address of the user terminal corresponding to the terminal identification from the received attribute information of the user terminal sent by the user terminal according to the terminal identification.
Step 302, the MEC server determines the service session carrying the service IP address and the terminal IP address in each service session of the network bandwidth to be allocated as the target service session.
Each business conversation carries a source address and a target address, and the MEC server determines the business conversation in which the source address in the business conversation of each network bandwidth to be distributed is a searched terminal IP address and the target address is a service IP address in the business bandwidth application information as the target business conversation.
Therefore, the MEC server determines a target service session from each service session to be allocated with the network bandwidth according to the terminal identifier and the service IP address, further allocates the network bandwidth to the user terminal according to the size relationship between the application bandwidth and the residual bandwidth, configures air interface bandwidth application information according to the service bandwidth application information, and sends the air interface bandwidth application information to the base station, so that the base station allocates the air interface bandwidth to the user terminal according to the air interface bandwidth application information, performs network side bandwidth guarantee and air interface side bandwidth guarantee on a user using the target application, and improves the experience quality of the user on the target application.
In one embodiment, based on the above-described embodiment shown in fig. 2, referring to fig. 4, this embodiment relates to a process of how the MEC server allocates network bandwidth to the user terminal according to a size relationship between the requested bandwidth and the remaining bandwidth. As shown in fig. 4, the process includes steps 401, 402, and 403:
in step 401, the MEC server detects whether the requested bandwidth is greater than the remaining bandwidth.
In the embodiment of the application, the service bandwidth application information further includes a user level corresponding to the user terminal, and the user level may be an account level corresponding to a user account after the user registers the user account in the target application. For example, the target application is a game application, and is provided with a plurality of different user levels (such as a common user, a VIP user, a super VIP user, and the like), and after the user registers the user account, the user may pay to upgrade the account level to the VIP user, the super VIP user, and the like, or may not upgrade the account, and then the account level is the common user.
In the embodiment of the application, the size of the application bandwidth included in the service bandwidth application information is positively correlated with the user level included in the service bandwidth application information, that is, the higher the user level is, the larger the application bandwidth is, that is, compared with a common user, the application bandwidth is applied for a VIP user, so that the experience quality of an important user is improved.
As described above, the MEC server updates the remaining bandwidth once every time the network bandwidth is allocated, and stores the latest remaining bandwidth. The MEC server detects whether the requested bandwidth is larger than the latest remaining bandwidth.
Step 402, if the applied bandwidth is greater than the residual bandwidth, the MEC server determines the target priority of the target service session according to the user level, and detects whether there is an allocated bandwidth service session with a priority lower than the target priority.
If the application bandwidth is greater than the remaining bandwidth (for example, the remaining bandwidth is 3Mbps, and the application bandwidth is 5Mbps), that is, the remaining bandwidth is insufficient, in order to improve the experience quality of the user with a higher user level, that is, in order to allocate more network bandwidth to the user terminal with a higher user level, the MEC server first determines the target priority of the target service session according to the user level.
In the embodiment of the present application, the target priority of the target service session is positively correlated with the user level corresponding to the user terminal, that is, the higher the user level is, the higher the priority is. In a possible implementation manner, the MEC server may preset a mapping relationship between each user class and each priority, and the MEC server searches the mapping relationship according to the user class of the user terminal, so as to obtain the target priority of the target service session.
After determining the target priority of the target service session, the MEC server detects whether the allocated bandwidth service session with the priority lower than the target priority exists. For example, the target priority is a high priority, the MEC server identifies the traffic session priority of each allocated bandwidth, compares the traffic session priority of each allocated bandwidth with the target priority, and detects whether there is an allocated bandwidth traffic session with a priority lower than the target priority.
Step 403, if there is a bandwidth allocated service session, the MEC server calculates a network bandwidth contraction value of the bandwidth allocated service session, and contracts the network bandwidth of the bandwidth allocated service session according to the network bandwidth contraction value, and uses the sum of the residual bandwidth and the bandwidth contraction value as the network bandwidth allocated to the user terminal.
And if the MEC server detects that the allocated bandwidth service session with the priority lower than the target priority exists, the MEC server calculates a network bandwidth contraction value of the allocated bandwidth service session so as to contract the network bandwidth of the allocated bandwidth service session.
In one possible embodiment, the number of allocated bandwidth service sessions is multiple, e.g., the target priority of the target service session adopts PJIndicating that the MEC server detects that the priority of the allocated bandwidth service session 1 is P1The priority of the allocated bandwidth service session 2 is P2.. priority of allocated bandwidth service session J-1 is PJ-1And P is1,P2,...,PJ-1,PJThe priority is sequentially increased, and the MEC server further calculates the network bandwidth contraction value of each allocated bandwidth service session.
Referring to fig. 5, fig. 5 is a flowchart of the MEC server calculating a network bandwidth contraction value of an allocated bandwidth service session. As shown in fig. 5, the process includes steps 501, 502, and 503:
step 501, the MEC server obtains a bandwidth contraction factor of each allocated bandwidth service session.
Wherein, for each allocated bandwidth service session, the size of the bandwidth shrinking factor of the allocated bandwidth service session and the priority of the allocated bandwidth service session are inversely related. For example, priority P1,P2,...,PJ-1Corresponding bandwidth shrinkage factor of alpha1,α2,...,αJ-1I.e. with a priority of P1The bandwidth contraction factor of the allocated bandwidth service session is alpha1Priority is P2The bandwidth contraction factor of the allocated bandwidth service session is alpha2.. priority is PJ-1The bandwidth contraction factor of the allocated bandwidth service session is alphaJ-1And P is1,P2,...,PJ-1,PJThe priority being successively higher, α1>α2>...>αJ-1。
In the embodiment of the present application, the bandwidth shrinking factor of each allocated bandwidth service session may be set based on manual experience.
Step 502, for each allocated bandwidth service session, the MEC server determines a shrinkage coefficient corresponding to the allocated bandwidth service session according to each bandwidth shrinkage factor.
In the embodiment of the present application, priority P is assumed1,P2,...,PJ-1The number of corresponding allocated bandwidth service sessions is N1,N2,...,NJ-1I.e. the presence of N1The priority of the allocated bandwidth service session is P1In the presence of N2The priority of the allocated bandwidth service session is P2.. existence NJ-1The priority of the allocated bandwidth service session is PJ-1。
The MEC server may calculate the shrinkage factor corresponding to the allocated bandwidth service session by using the following formula 1:
Figure BDA0002822631270000131
1≤m≤J-1
wherein, CmIs priority PmOf an allocated bandwidth service session, alphamIs priority PmCorresponding bandwidth contraction factor.
Thus, for each allocated bandwidth service session, the MEC server may calculate the shrinkage coefficient corresponding to each allocated bandwidth service session according to each bandwidth shrinkage factor and formula 1.
In step 503, the MEC server calculates a difference between the requested bandwidth and the remaining bandwidth, and takes the product of the difference and the contraction coefficient as the network bandwidth contraction value of the allocated bandwidth service session.
And the MEC server calculates the difference between the application bandwidth and the residual bandwidth, and for each allocated bandwidth service session, the MEC server takes the product of the difference and the contraction coefficient of the allocated bandwidth service session as the network bandwidth contraction value of the allocated bandwidth service session. And the MEC server contracts the network bandwidth of the allocated bandwidth service session according to the network bandwidth contraction value, so as to release the network bandwidth corresponding to the network bandwidth contraction value.
And the MEC server sums the network bandwidth contraction values of all the allocated bandwidth service sessions, sums the summation result with the residual bandwidth to obtain a target bandwidth, wherein the target bandwidth is the network bandwidth allocated to the user terminal, and the MEC server allocates the network bandwidth to the user terminal according to the size of the target bandwidth.
In another possible implementation, the number of allocated bandwidth service sessions may also be 1, and the manner of calculating the contraction coefficient of the allocated bandwidth service sessions is as described above, and is not described herein again.

After receiving the air interface bandwidth application information, the base station determines a target service session according to an air interface identifier, and calculates the number of bits to be scheduled of the target service session in a Transmission Time Interval (TTI); and during each TTI scheduling period, the base station sequences the service sessions to be allocated with the air interface bandwidth according to the priority corresponding to the user level, and preferentially allocates the air interface bandwidth to the service sessions with high priority. In the distribution process, the base station synthesizes the factors such as the quality of the air interface wireless environment, the number of the dispatching bits and the like to execute dispatching, and distributes air interface bandwidth for the user terminal.
Therefore, the MEC server opens bandwidth guarantee aiming at the target service session at the network side and the air interface side, and can improve the matching degree of the network bandwidth and the air interface bandwidth of the user terminal, thereby improving the data transmission efficiency of the target service session in the process of accessing the target application by the user terminal and improving the application access experience of the user. And in the process of bandwidth allocation, the user level is combined, so that high-quality service experience is provided for users with high user levels, and the increment of value added services is facilitated.
