Method and device for controlling wireless network resources

technical field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and an apparatus for controlling wireless network resources.

Background technique

At present, the wireless network of mobile communication is still built according to the traditional architecture, as shown in Figure 1, that is, the mobile base station (such as eNB) accesses the core network (EPC) through the transmission equipment (PTN), and the service source or service platform equipment It is placed in the IDC computer room behind the core network or in the enterprise's own location. Between the core network and the service source, there will also be many backbone network devices, lines, Ethernet devices, etc., and the link devices along the way will involve many operators or enterprises.

Mobile Edge Computing (MEC, Mobile Edge Computing) is an emerging network technology oriented to 5G evolution. To the wireless access side, the service data accessed by the user can not pass through numerous devices and links in the core network and the public network, thereby greatly reducing the service delay and greatly improving the service end-to-end rate. End users in the network area using the mobile edge computing technology can experience the services provided by the mobile edge computing technology solution while enjoying ordinary telephone and data Internet services.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts 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. Acquire the comprehensive cell load degree of each cell in the local network, and the cell comprehensive load degree is used to indicate the load situation of the cell;

S102. When it is determined that the comprehensive cell load degree of the first cell in the local network reaches a first threshold value, send a first adjustment instruction to the base station of the first cell, where the first adjustment instruction is used to instruct to reduce each MEC in the first cell The maximum bandwidth value that can be allocated to a user; the MEC user here is a user whose current service includes MEC service.

In the method for controlling wireless network resources provided by the embodiment of the present invention, when it is detected that the comprehensive cell load degree of the first cell in the local network is greater than the first threshold value, sending a message to the base station of the first cell to reduce the MEC in the first cell The first adjustment instruction of the maximum bandwidth value of the user, so that the base station can adjust the maximum bandwidth value of the MEC user in the cell accordingly after receiving the instruction, so as to alleviate the influence of the large number of air interface resources in the cell due to excessive MEC services. The phenomenon of normal use of non-MEC services can effectively control the resource usage of MEC services to achieve balanced allocation of air interface resources in cells.

In practical applications, the methods provided in the above embodiments may be implemented at the MEC device (mobile edge computing device) as shown in FIG. 2 , and of course may also be implemented at other network devices connected to various base stations, MEC devices and local service platforms. , which is not specifically limited in the present invention. For the convenience of description, the specific implementation of the method provided by the embodiment of the present invention is described below by taking the implementation of the method at the MEC device as an example.

In practical applications, reducing the maximum bandwidth value that can be allocated to each MEC user in the first cell in the above method embodiments may specifically refer to: reducing the UE-AMBR parameter of each MEC user in the first cell, the UE-AMBR parameter It is an important parameter for setting the service bandwidth of a single user. AMBR (Aggregate Maximum Bit Rate, Aggregate Maximum Bit Rate), UE-AMBR defines the upper limit of the bit rate that can be occupied by multiple bearers of each user.

It is not difficult to see that the reduction of the UE-AMBR parameter of each MEC user in the first cell here only limits the total service bandwidth of a single user, and does not control the total number of users and total service. However, in specific implementation, it can be understood that with the development of MEC services, the number of MEC users in each cell may increase, resulting in an increase in cell load, and the method of reducing the total service bandwidth of a single user may not be able to Meet the needs of resource allocation.

Based on this, an embodiment of the present invention provides a second method for controlling wireless network resources, as shown in FIG. 4 , including:

S201. Obtain the comprehensive cell load degree of each cell in the local network, and the cell comprehensive load degree is used to indicate the load situation of the cell;

S202. When it is determined that the comprehensive cell load degree of the first cell in the local network reaches the first threshold and is less than the second threshold, send a first adjustment instruction to the base station of the first cell; after determining that the first cell in the local network When the comprehensive load degree of the first cell reaches the second threshold, send a second adjustment instruction to the base station of the first cell, and the second adjustment instruction is used to instruct to reduce the total bandwidth of all MEC users in the first cell;

Wherein, the MEC user is a user whose current service includes the MEC service.

The embodiment of the present invention monitors the load condition of the cell by setting double thresholds, and adopts a two-layer step-by-step method to control the radio resources of the cell, so that the radio resource control method can be adapted to the network under various load conditions. According to different circumstances, effective measures that can effectively alleviate the current load situation can be adopted, so as to realize the balanced allocation of wireless resources and maximize the cell traffic and user experience.

Wherein, the first threshold value and the second threshold value here can be flexibly set according to the operator's requirement and the running condition of the current network, and can float between 0-100%. For example, the first threshold value may be set to 10%, and the second threshold value may be set to 50%. During use, the network operation can also be monitored in real time, and the threshold value can be dynamically adjusted according to the actual network conditions.

In addition, the second adjustment instruction here may be further used to instruct the base station to reduce the total bandwidth of all MEC users in the first cell by a preset step C, but the reduced total bandwidth needs to be greater than the preset minimum total bandwidth value D. Among them, the adjustment step C of the total bandwidth of MEC users can be flexibly set according to the needs of the operator and the running conditions of the existing network, and the minimum total bandwidth D can be set according to the business requirements signed by the operator and the enterprise applying for MEC service or the operator Set the running load of the current network. For example, the initial value of the total bandwidth of MEC users is 50PRB, the adjustment step size of the total bandwidth of MEC users can be set to 10PRB, and the minimum total bandwidth of MEC users is 20PRB. During use, network monitoring personnel can also monitor the network operation in real time and make timely adjustments according to the actual network conditions.

In order to finely control 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 by the embodiment of the present invention further includes:

S204. Send a third adjustment instruction to the base station of the first cell, where the third adjustment instruction is used to instruct: control the access of the MEC users in the first cell to the local service platform according to the priority ordering of the MEC service; and/or , the radio resource scheduling of the MEC users in the first cell is controlled according to the priority ordering of the users.

That is, based on the reduced total allowable load of non-MEC users and total allowable load of MEC users, resource scheduling is performed on non-MEC users and MEC users according to ARP and QCI, respectively. Among them, ARP is used to measure the user's contribution to the network, including traffic contribution and call charge contribution; QCI (QoS Class Identifier) is a scale value used to measure the specific packet forwarding behavior provided to SDF (service data flow) (such as Packet loss rate, packet delay budget), it is applied to both GBR and Non-GBR bearers, and is used to specify the control bearer-level packet forwarding method defined in the access node (such as scheduling weight, admission threshold, queue management threshold, link layer protocol) configuration, etc.) These are pre-configured into the access network nodes by the operator. Both ARP and QCI are important parameters commonly used by base stations when scheduling resources for users.

Wherein, for all the MEC users in the cell: according to the adjusted upper limit of the total bandwidth of the MEC service M-MBR, each MEC user can be scheduled according to the ARP and QCI priorities. Specifically, each MEC service is sorted first according to the QCI priority, and the user access of the high-priority service is ensured first, and the service guarantee of the low-priority service is reduced or interrupted. Then, according to the user's ARP priority, the radio resource allocation of users with high ARP is guaranteed first, and the guarantee of low-priority users is reduced or interrupted; for all non-MEC users in the cell, within the remaining bandwidth excluding the MEC service bandwidth, the same The ARP priority of the user and the QCI priority of the service are scheduled. The scheduling method here is similar to that of the MEC user, except that the QCI here is the QCI of the common service.

The advantage of this is that after reducing the total bandwidth of the MEC service in the cell, reasonable resource allocation adjustment measures can be carried out for different MEC services and users of different levels to ensure that services or users with high priority can be preferentially allocated to wireless resources. .

In addition, in the specific implementation, the obtaining of the comprehensive cell load degree of each cell in the local network in steps S101 and S201 in the above method embodiments can be implemented in various ways, and an optional implementation way is: obtaining the local Several cell load factors corresponding to each cell in the network, several cell load factors include: cell user activation rate, PRB percentage, and operation KPI of the specified service type; according to several cell load factors corresponding to the first cell and each load The comprehensive load degree of the first cell obtained by the weight corresponding to the factor.

Specifically, the comprehensive load degree of the cell is a factor defined in the present invention to comprehensively measure the load situation of the cell, and the load degree can be determined by factors such as the user activation rate of the cell, the percentage of PRBs, and the operation KPIs of the key service types. . like:

The comprehensive load degree of the cell = a*X+b*Y+c*Z, where:

(1) X represents the cell user activation rate, which represents the density of activated users in the cell;

(2) Y represents the percentage of PRB resources occupied in the cell, which represents the load degree of the radio resources in the cell;

(3) Z is determined by the operation KPIs of the key service types, which represent the performance of the key services in the cell, such as the connection rate of the cell voice service; when the KPI is better than or equal to the operator’s KPI assessment requirements, Z = 0; when the KPI is worse than the operator's KPI assessment requirement within 1%, Z = 0.7; when the KPI is worse than the operator's KPI assessment requirement by more than 1%, Z = 1;

xi.a, b, c represent the weights of X, Y, and Z respectively, and the values can be between 0-1.

Through the above expression, the comprehensive load degree of each cell can be obtained.

It should be noted that the activation rate of cell users, the percentage of PRBs, and the operation KPIs of key service types are only a few factors selected by the embodiment of the present invention according to the status of an existing local network, which can affect. Factor for cell load conditions. In actual situations, of course, only one of the factors can be selected according to different requirements, or other factors can be introduced, which is not specifically limited in the present invention.

In addition, it should also be noted that the "obtaining several cell load factors corresponding to each cell in the local network" here can actively obtain load factors for each base station that calls the MEC device to connect to the MEC device; it can also mean that the base station actively asks the MEC The device reports the above load factor, and the method provided by the present invention then acquires and processes the load factor received by the MEC device, which is not specifically limited in the present invention.
