The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely illustrative of the manner in which embodiments of the application have been described in connection with the description of the objects having the same attributes. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Before describing the embodiments of the present application, the related content of the radio access network will be briefly described to facilitate the subsequent understanding of the embodiments of the present application.

The current resource planning of the wireless access network is divided into wireless planning, transmission planning and equipment planning, wherein the wireless planning is used for planning the demand for wireless resources according to the service demand, including wireless network demands such as wireless coverage points, cells and the like; the transmission planning is used for planning out the requirement for transmission according to the wireless network requirement obtained by the wireless planning, and the requirement comprises the number of transmission ports, bandwidth and the like; the device planning is used for planning the demand of the device according to the wireless network demand and the transmission demand, and evaluating and selecting the device matched with the demand.

The current equipment planning mainly uses a network management system to quantitatively match the service requirement with the network equipment in the wireless access network by taking a cell as a quantization dimension, mainly converts the service requirement to be borne by the wireless access network into a cell number requirement according to capacity, simultaneously obtains the cell number specification supported by the hardware capability of the network equipment in the wireless access network, quantitatively matches the cell number requirement corresponding to the service requirement with the cell number specification supported by the network equipment, and determines the number of the network equipment meeting the service requirement so as to ensure that the wireless access network can meet the service requirement and normally deploy the service. The hardware capability of the network device is determined by hardware resources, where the hardware resources include data processing resources, data storage resources, data transmission resources, carrier resources, channel transmitting capability, etc., and it is understood that other hardware resources are also included in the actual situation, and the present invention is not limited herein.

However, the device resource is only planned and evaluated by taking the cell as the quantization dimension, so that the requirement of the service requirement on the capacity can be met, and in practical application, the phenomenon that the instantaneous concurrent service to be borne by the wireless access network is more exists, and at the moment, the wireless access network can not meet the concurrent requirement of the service, so that the SLA of the service can not be ensured, and the user experience is affected.

In order to solve the above-mentioned problems, the embodiments of the present application first provide a method for evaluating the service demand on a wireless access network and related devices, which are applied to the internet industry. The network management system receives a service requirement, wherein the service requirement is a requirement of a service to be carried by the wireless access network. And the network management system acquires a capability baseline of the network equipment, wherein the capability baseline at least comprises a first TTI concurrent scheduling number of the network equipment, the first TTI concurrent scheduling number is the TTI concurrent scheduling number of the network equipment, and the TTI concurrent scheduling number is the maximum number of users which can be scheduled in a minimum scheduling period. The network management system then determines a resource policy based on the traffic demand and the capability baseline, the resource policy indicating a number of network devices that meet the traffic demand. The number of the network devices meeting the service requirements is determined through the first TTI concurrency adjustment number containing the network devices and the service requirements, so that the TTI concurrency capability of the network devices can be guaranteed to meet the concurrency requirements of the services, the service SLA is guaranteed, and the user experience is improved.

In order to facilitate understanding of the following embodiments of the present application, a number of scheduled users will be activated in each scheduling period in a network system to send a data packet to be processed, where each TTI corresponds to a minimum scheduling time unit, and the TTI concurrency scheduling number is a number of users that can be scheduled most in one scheduling period and is generally divided into an uplink TTI concurrency scheduling number and a downlink TTI concurrency scheduling number.

For a better understanding of the embodiments of the present application, a method for evaluating a service requirement of a radio access network provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings. As one of ordinary skill in the art can know, with the development of technology and the appearance of new scenes, the technical scheme provided by the embodiment of the application is also applicable to similar technical problems. Referring to fig. 1 specifically, fig. 1 is a schematic flow chart of evaluating a service requirement on a radio access network according to an embodiment of the present application, which specifically includes:

101. a business requirement is received.

Specifically, the network management system receives a service requirement, where the service requirement is a requirement of a service to be carried by the radio access network. Taking the scenario of the wireless access network as an example, the wireless access network achieves the purpose of deploying the service by meeting the service requirement of the terminal under the condition of executing the service. The service may be a call request, a video request, a voice message, a web page refresh, or an operation instruction of an industrial device, an industrial monitoring service, or an industrial control service, which are not limited herein.

The following description will respectively take a scenario of setting up a wireless access network and a scenario of deploying a service on an existing wireless access network as an example, so as to facilitate understanding of embodiments of the present application. The method specifically comprises the following steps:

referring to fig. 2, fig. 2 is a schematic diagram illustrating a scenario of establishing a radio access network to determine network equipment requirements, where, when the radio access network is established, service requirements are determined in advance according to the established environment and sent to a network management system, where the service requirements include at least service requirements, service features, requirements related to services such as a network establishment policy, etc., and it is understood that other requirements exist in actual situations, and the application is not limited in this specific situation.

In addition, referring to fig. 3, fig. 3 is a schematic diagram illustrating a network device requirement determined by a scenario of a service deployment of an existing radio access network according to an embodiment of the present application. The service is deployed on the existing wireless access network, and the deployed service requirement needs to be determined so that the wireless access network can determine whether the service can be deployed or not based on the service requirement. The service requirements at least include service requirements, service characteristics, network construction policies and other service related requirements, and it is understood that there are other requirements in practical situations, and the application is not limited herein.

102. A capability baseline of the network device is obtained.

A capability baseline for the network device is obtained, the capability baseline indicating a first TTI including the network device and a modulation number. And the network device may be a base station, a network access gateway, or the like for a terminal to access a network or the like.

Specifically, the capability baseline of the network device, that is, the performance index of the network device, where the capability baseline includes at least a first TTI concurrent scheduling number of the network device, where the first TTI concurrent scheduling number is used to indicate a number of users that can be scheduled to the maximum in a scheduling period of the network device. Optionally, the first TTI concurrency adjustment number includes a first uplink TTI concurrency adjustment number of the network device and/or a first downlink TTI concurrency adjustment number of the network device. The first uplink TTI concurrency scheduling number is used for indicating the maximum number of users which can be scheduled in one scheduling period in the uplink, and the first downlink TTI concurrency scheduling number is used for indicating the maximum number of users which can be scheduled in one scheduling period in the downlink. In the embodiment of the application, the first TTI concurrent scheduling number comprises the first uplink TTI concurrent scheduling number and/or the first downlink TTI concurrent scheduling number, so that the network equipment capacity can be more accurately determined, and the number of the network equipment can be more accurately determined according to the service requirement.

Referring to fig. 4, fig. 4 is a schematic diagram of a first TTI concurrency scheduling degree in a capability baseline provided by an embodiment of the present application, where a network device, that is, a board type is UBBPg3, where UBBPg3 is a board type of a universal baseband processing board, the system of the board is 5G (FFD), the FFD is used to indicate a frequency division duplex technology, the frequency band range of the board is Sub3G, sub3G refers to a frequency range below 3GHz, the first uplink TTI concurrency scheduling degree and the first downlink concurrency scheduling number of the board are respectively 72, and the first uplink+downlink TTI concurrency scheduling degree is 144. From this, it can be understood that the first TTI of the UBBPg3 board in the network device and the modulation number are merely used as examples to understand the embodiment of the present application, and other types of boards may be actually used, which is not limited herein.

In one possible implementation, the capability baseline is obtained from the network device, or from device data provided by the manufacturer of the network device. For example, in the following description, a wireless access network scenario is taken as an example, where, as shown in fig. 2, when the wireless access network is set up, the network management system may obtain a capability baseline from device data provided by a provider, that is, a manufacturer, of the network device, so as to determine, based on the capability baseline, the number of network devices required to set up the wireless access network, and it is understood that, in general, the manufacturer of the network device may provide device data related to performance, so that a user may apply the network device based on the device data. As described in fig. 3, when deploying services in an existing radio access network, the network management system may directly obtain a capability baseline from network devices in the radio access network, so as to determine whether the existing network devices in the radio access network satisfy the deployment services based on the capability baseline, and determine the number of network devices that are required based on the capability baseline if they do not satisfy.

In the embodiment of the application, the capability baselines are acquired from the network equipment or the equipment data provided by the manufacturer of the network equipment, so that the multi-application scene of the scheme is increased, and the selectivity of the scheme is embodied.

103. Resource policies are determined based on business needs and capability baselines.

Specifically, after receiving the service requirement and acquiring the capability baseline of the network device, the network management system determines the number of network devices required to satisfy the service requirement based on the service requirement and the capability baseline. For example, the following description will take an application scenario of a radio access network as an example, and refer specifically to fig. 5 and fig. 6, where fig. 5 is another schematic diagram of determining a network device requirement in a scenario where a radio access network is built according to an embodiment of the present application, and fig. 6 is another schematic diagram of determining a network device requirement in a scenario where an existing radio access network deployment service is provided according to an embodiment of the present application.

In fig. 5, the network management system obtains the service requirement to be planned in step 501, which is similar to that described in the previous step 101, and is not described here again. The network management system then obtains capability baselines for the network device from the device data, which is provided by the provider, i.e., vendor, of the network device, as step 502. The network management system then performs step 503, i.e. the network management system determines a resource policy based on the service requirement and the capability baseline, so as to obtain the number of network devices required for building the wireless access network, thereby completing building the wireless access network to meet the service requirement of the current environment.

In fig. 6, the network management system obtains the service requirement to be deployed, which is similar to that described in the previous step 101, and is not described in detail here. Then, as in step 602, the network management system directly obtains the capability baseline of the network device from the network device in the radio access network, and then executes step 603, namely, the network management system determines a resource policy based on the service requirement and the capability baseline, so that the number of network devices required by the radio access network to satisfy the service to be deployed can be determined according to the resource policy. In one possible implementation, in case an existing network device in the network does not meet the resource policy, the data of the network device to be added is determined based on the resource policy. Illustratively, in the case that the existing network devices in the radio access network do not satisfy the resource policy, as in step 604 in fig. 6, the network management system determines the number of network devices to be added based on the resource policy, so as to perfect the radio access network based on the number of network devices to be added, so as to satisfy the service requirement to be deployed. Optionally, in the case that the network device in the radio access network satisfies the resource policy, the radio access network deploys the service directly. In the embodiment of the application, under the condition that the network equipment in the network does not meet the resource policy, the network management system determines the number of the network equipment to be added based on the resource policy, thereby increasing the application scene, further ensuring that the network equipment can meet the service requirement and improving the experience of users.

In a possible implementation manner, a cell number requirement corresponding to the coverage point location and a second TTI concurrent modulation number are determined based on the service requirement, and then a resource policy is determined based on the cell number requirement, the second TTI concurrent modulation number and the capability baseline. The capacity base line further comprises a cell number specification supported by the network equipment, the coverage point position is a geographic position of the network equipment in the wireless access network, and the number of the network equipment meeting the service requirement comprises the number of the network equipment corresponding to the coverage point position.

Specifically, the network management system determines the cell number requirement corresponding to the coverage point according to the service requirement, where the coverage point is a geographic location where the network device in the wireless access network belongs, and the number of the coverage point is at least one. In addition, the network management system determines the second TTI concurrency adjustment number corresponding to the coverage point based on the service requirement, and fig. 7 may refer to fig. 7, where fig. 7 is a schematic diagram of the matching network device provided in the embodiment of the present application, and the network management system may perform service simulation through specific service requirements such as a packet sending interval, a packet sending size, a packet sending duration, a service direction, a service flow number, a terminal number, and a terminal position to obtain the second TTI concurrency adjustment number corresponding to the coverage point, and the simulation may use a monte carlo statistical method, or other similar methods capable of achieving the same purpose, which are not limited in this specific application. And optionally, the second TTI concurrent scheduling number includes a second uplink TTI concurrent scheduling number corresponding to the service requirement and/or a second downlink TTI concurrent scheduling number corresponding to the service requirement. The second uplink TTI concurrent scheduling number is used for indicating the maximum number of users which can be scheduled in one scheduling period in the uplink, and the second downlink TTI concurrent scheduling number is used for indicating the maximum number of users which can be scheduled in one scheduling period in the downlink. In the embodiment of the application, the second TTI concurrency adjustment degree comprises the second uplink TTI concurrency adjustment degree and/or the second downlink concurrency adjustment degree, so that the number of network devices can be determined based on the second uplink TTI concurrency adjustment degree and/or the second downlink concurrency adjustment degree more accurately, the concurrency requirement of the service is met by the network devices, the service SLA is ensured, the user experience is improved, and the 5G to B industry development is facilitated.

Then, the network management system determines a resource policy, i.e. the number of network devices, based on the cell number requirement, the second TTI and the scheduling number, and the capability baseline, specifically including: the network management system firstly determines the number of network devices which correspond to the coverage point positions and meet the requirements of the service on capacity based on the cell number requirements corresponding to the service requirements and the cell number specifications of the network devices included by the capacity base line. Then as shown in fig. 7, the network management system matches the second TTI concurrency modulation number corresponding to the coverage point and the first TTI concurrency modulation number in the capability baseline to obtain the number of network devices corresponding to the coverage point and meeting the concurrency requirement of the service, and then further determines the number of network devices of the coverage point according to the number of network devices simultaneously meeting the capacity and concurrency requirement of the service, so that the obtained resource policy includes the number of network devices corresponding to all the coverage points in the wireless access network, that is, the specific distribution number of the number of network devices meeting the service requirement in each coverage point. Taking the above-mentioned single board shown in fig. 4 as an example, one UBBPg3 single board can meet the cell number requirement corresponding to the service requirement, where the second uplink TTI concurrency scheduling number corresponding to the service requirement is 100, the second downlink TTI concurrency scheduling number is 100, and according to the first uplink TTI concurrency scheduling number and the first downlink TTI concurrency scheduling number included in the capability baseline of the UBBPg3 single board shown in fig. 4, the service requirement needs that the UBBPg3 single board number is MAX (the second uplink TTI concurrency scheduling number divided by the first uplink TTI concurrency scheduling number is rounded up, the second downlink TTI concurrency scheduling number divided by the first downlink TTI concurrency scheduling number is rounded up) =2, so that the service requirement can be met by two UBBPg3 single boards. From this it can be determined that the resource policy, i.e. the number of demands of the network device, is 2.

It can be understood that in the embodiment of the application, the network management system determines the resource policy based on the cell number requirement corresponding to the coverage point location and the second TTI and transmits the scheduling number and the capacity baseline of the network device, so that the number of network devices corresponding to all the coverage points in the wireless access network meeting the service requirement can be obtained, the number of network devices in the wireless access network can be ensured to meet the capacity and concurrency aspect of the service requirement at the same time, further the normal operation of the service is accurately ensured, the SLA of the service is ensured, the user experience is improved, the loss in the industry is reduced, and the 5G is beneficial to the development of the to B industry.

It can be understood that the application scenario of the above wireless access network is only used to understand the embodiment of the present application, and the determining the number of network devices based on the second TTI scheduling number in the service requirement and the first TTI scheduling number included in the capability baseline may also be applied to application scenarios such as a core network, a transmission network, and the like, which is not limited herein.

In the embodiment of the application, a network management system receives a service demand and acquires a capacity baseline of network equipment, wherein the capacity baseline at least comprises a first TTI of the network equipment and a modulation number, and the network management system determines a resource strategy based on the service demand and the capacity baseline, and the resource strategy is used for the number of the network equipment meeting the service demand. The method comprises the steps of determining a corresponding second TTI concurrency adjustment degree based on service requirements, determining the number of network devices based on the first TTI concurrency adjustment degree and the second TTI concurrency adjustment degree, and guaranteeing the concurrency requirements of the service, so that the service SLA is guaranteed, the user experience is improved, the loss in the industry is reduced, and the 5G is beneficial to the to B industry development.
