Description
Technical Field
The embodiment of the invention relates to the technical field of mobile communication, in particular to a video information processing method and a server.
Background
The radio network planning and design refers to the process of primarily planning the geographic position of the base station after obtaining the radio network planning requirement of the planning area, which is completed by the relevant steps of radio environment analysis, scale estimation, topology structure design, network pre-planning simulation and the like.
At present, the problem of inaccurate ground object information acquisition exists in the planning and design of a wireless network. Specifically, in the process of determining the requirement of the wireless network planning, a digital map is generally adopted to acquire the ground feature information of the wireless propagation environment, the highest precision is usually 5 meters, the precision is low, and sufficient three-dimensional (3D) ground feature information such as tree height and the like is lacked. Meanwhile, the timeliness of the ground object information is lower due to the fact that the updating time of the map is slower. The ground object information in the wireless propagation model is basic data of network simulation analysis, and the problems of poor ground object information effectiveness, insufficient precision, partial ground object information deficiency and the like inevitably influence the accuracy of a wireless network planning design scheme. In addition, the base station currently has only one position information, which is provided by the global positioning system (Global Positioning System, GPS) antenna of the base station, and in practice, the distance between the antennas of several cells in the same base station often reaches or even exceeds several tens of meters, and the sharing of one longitude and latitude position information by several pairs of antennas also reduces the accuracy of the scheme.
On the other hand, when planning and designing a wireless network, there is a problem that the display capability is limited. In the planning and design of a wireless network, network analysis and scheme formulation are generally performed by adopting a common personal computer (Personal Computer, PC) mode. The information display capability of the common PC is very limited, so that a planner cannot comprehensively observe the wireless network environment and the performance condition of the wireless network environment, and the network state information is difficult to comprehensively and intuitively analyze, so that the working efficiency is influenced. And the planning designer is required to perform on-site survey, mainly comprising preparation of survey tools (such as vehicles, intelligent survey terminals, GPS (global positioning system) positioners, digital cameras and the like), recording on-site survey conditions (such as antenna on-site environment photo records, antenna on-site size and direction positioning records and the like), arranging survey information (inputting information such as on-site photos and position sizes and the like into a PC), drawing design drawings and the like, and the workload is large.

and when the current traffic of the cell meets the preset condition, the radio frequency equipment transmits the first processing data to the baseband equipment of the base station through a common public radio interface CPRI or an Ethernet-based common public radio interface ECPRI.
In order to reduce the influence of the collection and the feedback of the video information (the radio frequency equipment transmits to the baseband equipment) on the common user, the video collection and the feedback can be performed when the traffic of the cell meets the preset condition according to the real-time uplink utilization rate of the cell and the preset uplink utilization rate threshold value.
Specifically, the traffic situation of the cell may be judged according to the following formula 1:
equation 1:
T＝Max(S1，M1)×M2-S2；
wherein, T is a traffic condition parameter, when the T value is greater than or equal to 0, determining that the current traffic of the cell meets a preset condition, otherwise, not meeting the preset condition;
S1 is a preset uplink utilization threshold, S2 is a real-time uplink utilization;

In the embodiment of the invention, the video information is transmitted back to the server by collecting the video information of the cell of the target area and utilizing the existing wired transmission resource of the network, so that the server generates a three-dimensional model of the target area by combining the position information of the base station and the video information, and the accuracy of the wireless propagation model is improved. Meanwhile, the acquisition frequency of the video information can be obviously improved, for example, the video information is set to be once a week, so that the real-time performance of the ground object information is improved. In the embodiment of the invention, the existing wired transmission resources of the CPRI or ECPRI interface of the existing network are utilized to transmit back the video information, so that the transmission capacity is improved, the high-speed transmission of the video information can be ensured, and meanwhile, precious network air interface resources are not occupied and the use of common mobile users is not influenced.

Su＝Se+ΔSm+ΔSs；
the Su is an updated field intensity value, se is a current field intensity value, deltaSm is field intensity change caused by three-dimensional model change, deltaSs is field intensity change value caused by base station scheme change (wherein DeltaSm and DeltaSs can be monitored in real time), and only the field intensity change part is needed to be calculated through the formula 2, and the whole network is not needed to be re-simulated, so that the calculated amount and calculation time delay are reduced, and the dynamic real-time simulation is realized, and the working efficiency is improved.
In the embodiment of the invention, the three-dimensional model of the target area sent by the server is received, the current network performance parameters in the target area are obtained, the current network performance parameters are superimposed into the three-dimensional model, the actual environment of the target area can be truly displayed through the VR terminal, the site survey work of planning designers can be replaced, the situation that the planning operators can accurately analyze the network performance state in an omnibearing manner is realized, the planning design scheme can be effectively output, and the problem that the display capability is limited in the planning and design of the wireless network in the prior art is solved.
