At present, a wireless network for mobile communication is still built according to a conventional architecture, as shown in fig. 1, that is: a mobile base station (such as eNB) accesses a core network (EPC) through a transmission device (PTN), and a service source or service platform device is placed in an IDC machine room behind the core network or in the self-owned position of an enterprise.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first aspect, an embodiment of the present invention provides a method for controlling wireless network resources, as shown in fig. 3, including:
s101, acquiring the comprehensive load degree of each cell in a local network, wherein the comprehensive load degree of each cell is used for representing the load condition of each cell;
s102, when determining that the comprehensive load width of a first cell in a local network reaches a first threshold value, sending a first adjusting instruction to a base station of the first cell, wherein the first adjusting instruction is used for indicating to reduce the maximum bandwidth value which can be allocated to each MEC user in the first cell; the MEC user here is a user of the currently used service including the MEC service.
In the method for controlling wireless network resources provided in the embodiment of the present invention, when it is detected that the cell integrated load of the first cell in the local network is greater than the first threshold, a first mediation instruction for reducing the maximum bandwidth value of the MEC user in the first cell is sent to the base station of the first cell, so that the base station performs corresponding adjustment on the maximum bandwidth value of the MEC user in the cell after receiving the instruction, thereby alleviating a phenomenon that the normal use of a non-MEC service is affected because air interface resources of the cell are occupied in large quantities due to excessive MEC services, effectively controlling the resource usage of the MEC service, and implementing balanced allocation of the air interface resources of the cell.
In practical applications, the method provided by the foregoing embodiment may be implemented at an MEC device (mobile edge computing device) as shown in fig. 2, and of course, may also be implemented at other network devices connecting each base station, MEC device, and local service platform, which is not limited in this respect. For convenience of description, the following description will be made of a specific implementation of the method provided by the embodiment of the present invention, taking the implementation of the method at the MEC facility as an example.
In practical application, the reducing of the maximum bandwidth value that each MEC user in the first cell can be allocated in the foregoing method embodiment may specifically refer to: and reducing the UE-AMBR parameter of each MEC user in the first cell, wherein the UE-AMBR parameter is an important parameter for setting the single-user service bandwidth. AMBR (Aggregate Maximum Bit Rate), UE-AMBR defines an upper limit on the Bit Rate that can be occupied by multiple bearers per user in total.
It should be understood that the UE-AMBR parameter for each MEC user in the first cell is only limited to the total service bandwidth of a single user, and the total amount of users and the total amount of services are not controlled. However, in specific implementation, it can be understood that as the MEC service develops, the number of MEC users in each cell may increase, which causes the cell load to increase, and the resource allocation requirement may not be met by only reducing the total service bandwidth of a single user.
Based on this, an embodiment of the present invention provides a second method for controlling radio network resources, as shown in fig. 4, including:
s201, acquiring the comprehensive load degree of each cell in a local network, wherein the comprehensive load degree of each cell is used for representing the load condition of each cell;
s202, when determining that the comprehensive load degree of a first cell in a local network reaches a first threshold value and is smaller than a second threshold value, sending a first adjusting instruction to a base station of the first cell; when determining that the cell comprehensive load degree of a first cell in a local network reaches a second threshold value, sending a second adjusting instruction to a base station of the first cell, wherein the second adjusting instruction is used for indicating to reduce the total bandwidth of all MEC users in the first cell;
the MEC user is a user of the MEC service contained in the currently used service.
The embodiment of the invention monitors the load condition of the cell by setting double thresholds and regulates and controls the wireless resources of the cell by adopting a two-layer stepping method, thereby enabling the regulation and control mode of the wireless resources to be suitable for network environments under various load conditions, and adopting effective means capable of effectively relieving the current load condition aiming at different conditions, further realizing the balanced distribution of the wireless resources and achieving the purpose of maximizing the cell service volume and the user experience.
The first threshold value and the second threshold value can be flexibly set according to the requirements of operators and the current network operation condition and can float between 0 and 100 percent. For example, the first threshold value may be set to 10% and the second threshold value may be set to 50%. In the using process, the network operation condition can be monitored in real time, and the threshold value can be dynamically adjusted according to the actual network condition.
In addition, the second adjustment instruction herein may be further used to instruct the base station to decrease the total bandwidth of all MEC users in the first cell by a preset step size C, but the decreased total bandwidth needs to be greater than a preset minimum total bandwidth value D. The total bandwidth adjustment step length C of the MEC user can be flexibly set according to the requirements of an operator and the current network operation condition, and the minimum total bandwidth D can be set according to the service requirements signed by the operator and an enterprise applying for the MEC service provision or the current network operation load condition of the operator. For example: the initial value of the total bandwidth of the MEC users is 50PRB, the adjustment step size of the total bandwidth of the MEC users can be set to be 10PRB, and the total minimum bandwidth of the MEC users is 20 PRB. In the using process, network monitoring personnel can also monitor the network operation condition in real time and adjust in time according to the actual condition of the network.
In order to perform detailed control on the network resources of each user in the first cell after reducing the total bandwidth, after sending the second adjustment instruction to the base station of the first cell, the method provided in the embodiment of the present invention further includes:
s204, sending a third adjusting instruction to the base station of the first cell, wherein the third adjusting instruction is used for indicating that: controlling the access condition of MEC users in a first cell to a local service platform according to the priority sequence of the MEC services; and/or controlling the radio resource scheduling of the MEC users in the first cell according to the priority ranking of the users.
And respectively scheduling the resources of the non-MEC users and the MEC users according to the ARP and the QCI based on the reduced total allowable load of the non-MEC users and the reduced total allowable load of the MEC users. ARP is used for measuring the contribution of the user to the network, including flow contribution and telephone charge contribution; qci (qos Class identifier) is a scale value used to measure the packet forwarding behavior (e.g. packet loss rate, packet delay budget) of a specific SDF (service data flow), and it is applied to both GBR and Non-GBR bearers, and used to specify the control bearer level packet forwarding modes (e.g. scheduling weight, admission threshold, queue management threshold, link layer protocol configuration, etc.) defined in the access node, which are pre-configured by the operator into the access network node. Both ARP and QCI are important parameters commonly used by a base station when scheduling resources for a user.
Wherein, for all MEC users within a cell: and scheduling each MEC user according to the ARP and QCI priority according to the adjusted MEC service total bandwidth upper limit M-MBR. Specifically, the MEC services are sorted according to QCI priority, so that the user access of the high-priority service is guaranteed preferentially, and the service guarantee of the low priority is reduced or interrupted. According to the ARP priority sequence of the users, the wireless resource allocation of the users with high ARP is preferentially ensured, and the guarantee of the users with low priority is reduced or interrupted; and for all non-MEC users in the cell, scheduling according to the ARP priority of the users and the QCI priority of the service in the residual bandwidth except the MEC service bandwidth. The scheduling manner here is similar to that of the MEC user, except that the QCI here is the QCI of the ordinary service.
The method has the advantages that reasonable resource allocation adjustment measures can be carried out on different MEC services and different levels of users after the total bandwidth of the MEC services of the cell is reduced, and the services or the users with high priority can be preferentially allocated to the wireless resources.
In addition, in specific implementation, in the method embodiment, the acquiring of the cell comprehensive load degree of each cell in the local network in step S101 and step S201 may be implemented in multiple ways, where one optional implementation is as follows: obtaining a plurality of cell load factors corresponding to each cell in a local network, wherein the cell load factors comprise: the method comprises the following steps that (1) the cell user activation rate, the PRB proportion percentage and the operation KPI of a specified service type are obtained; and obtaining the comprehensive load degree of the first cell according to the load factors of the plurality of cells corresponding to the first cell and the weights corresponding to the load factors.
Specifically, the cell comprehensive load degree is a factor defined in the present invention for comprehensively measuring the cell load condition, and the load degree can be determined by considering factors such as the cell user activation rate, the PRB percentage, and the operation KPI of the service type of the important concern. Such as:
and the integrated load degree of the cell is a X + b Y + c Z, wherein:
(1) x represents the activation rate of the cell users and represents the intensity of the activated users in the cell;
(2) y represents the occupied percentage of the PRB resources of the cell, and represents the load degree of the wireless resources of the cell;
(3) z is determined by the operation KPI of the key concerned business type, and represents the performance of the key concerned business in the cell, such as the call completing rate of the cell voice business; when the KPI is better than or equal to the KPI assessment requirement of the operator, Z is 0; when the KPI is within 1% of the KPI assessment requirement of the operator, Z is 0.7; when the KPI is less than the KPI assessment requirement of an operator by more than 1%, Z is 1;
xi, a, b and c respectively represent the weight values of X, Y and Z, and the values can be all between 0 and 1.
The cell comprehensive load degree of each cell can be obtained through the expression.
It should be noted that the cell user activation rate, the percentage of PRB occupation, and the operation KPI of the service type of the important interest are only several factors that can affect the cell load condition, which are selected according to the present embodiment according to the present invention, according to the current situation of a local network. In practical cases, it is of course possible to select only one of the factors according to different requirements, or introduce other factors, which is not specifically limited by the present invention.
In addition, it should be further noted that "acquiring a plurality of cell load factors corresponding to each cell in the local network" herein may be to invoke the MEC device to actively acquire the load factors to each base station connected to the MEC device; the method provided by the present invention may further acquire and process the load factor received by the MEC device, which is not specifically limited in the present invention.
