In the related art, in order to effectively meet the requirements of high system throughput and user experience rate in a hotspot area, a large number of dense wireless access nodes, rich frequency resources and a novel access technology need to be introduced, so that the connection efficiency between the device and the wireless communication device cannot be ensured.
In this embodiment, the ultra-dense heterogeneous network refers to a network in which different types that overlap with each other are merged to meet the diversity requirement of a terminal service, and may include a high-speed wireless communication device, a low-speed wireless communication device, and the like, so that the high-speed wireless communication device and the low-speed wireless communication device may be mixed and grouped to form the heterogeneous group, which is used for transmitting a wireless signal to connect devices, for example, to connect internet of things devices for wireless communication, and the internet of things devices may include two types, namely real-time devices and non-real-time devices.

When the wireless communication device is connected with a plurality of devices, the existing power consumption value and the existing utility value of the wireless communication device can be gradually determined along with the connection of the devices and are updated in a superposition mode, when other devices to be connected request connection, the profit value can be determined according to the existing utility value of the connected devices and the preference value of the wireless communication device to the devices, the expense value can be determined according to the estimated power consumption of the wireless communication device after the wireless communication device is connected with the devices and the existing power consumption value of the wireless communication device to the original devices, and the estimated utility value is determined according to the profit value and the expense value to serve as an evaluation standard for pairing connection of the wireless communication device and the devices to be connected. In this embodiment, the pre-estimated utility value is used to comprehensively judge the profit and power consumption of the wireless communication device after being connected to the equipment, so that when the connection condition of the equipment is determined, the overall operation conditions of the wireless communication device and the equipment after being connected to the equipment can be measured, and then, each wireless communication device can be reasonably allocated to be connected to the equipment to be connected, thereby being beneficial to maximizing the connection efficiency of the wireless communication device and the equipment and reasonably allocating and controlling the power, the energy consumption and the like of the wireless communication device during connection, and further reducing the energy consumption of the operation of the wireless communication device.
When the device requests connection, the ultra-dense heterogeneous network receives the request, and can determine the pre-connection heterogeneous group to be used for pre-connection with the Internet of things device.
In this embodiment, each heterogeneous group has a plurality of wireless communication apparatuses, so that the plurality of wireless communication apparatuses can be numbered sequentially according to the order of connection rates, when a device to be connected is connected to a wireless communication apparatus in a pre-connected heterogeneous group, the estimated utility value can be determined according to the order of numbering the wireless communication apparatuses, when the estimated utility value meets the connection requirement, the wireless communication apparatus is connected to the device to be connected, so as to ensure that the device is connected to a higher-speed wireless communication apparatus, if the estimated utility value does not meet the connection requirement, the utility value of the wireless communication apparatus with the later connection rate is determined, so as to determine in turn until the wireless communication apparatus is connected to the device to be connected, or the estimated utility value of the wireless communication apparatus does not meet the connection requirement, so that the wireless communication apparatus in the pre-connected heterogeneous group is not connected to the device to be connected, and connecting the wireless communication devices of other heterogeneous groups except the pre-connection heterogeneous group in the ultra-dense heterogeneous network with the equipment to be connected, thereby more reasonably distributing the connection pairing of the wireless communication devices and the equipment and ensuring that the higher connection efficiency is achieved.
In an optional embodiment of the present invention, the determining, in the heterogeneous groups other than the pre-connection heterogeneous group in the ultra-dense heterogeneous network, that the wireless communication apparatus is connected to the device to be connected includes:

and connecting the wireless communication device corresponding to the selection value with the maximum value with the equipment to be connected.
In this embodiment, when the estimated utility values of the wireless communication devices in the heterogeneous group to be connected do not meet the requirement, the device to be connected and the wireless communication devices in other heterogeneous groups are connected in a pairing manner, so as to avoid that the utility value is low after the device to be connected is connected, which results in high connection efficiency due to high energy consumption, specifically, whether the device to be connected is connected with the wireless communication devices is determined according to the selection value of the device to be connected to the wireless communication devices, wherein the selection value represents the strength of the selection will of the device to be connected to the wireless communication devices, so as to ensure that the wireless communication devices and the device to be connected are connected in a better pairing manner.
The method comprises the steps of obtaining a preference value of the wireless communication device to the equipment to be connected and obtaining a connection quality value of the wireless communication device to the equipment to be connected; thereby determining the selection value according to the preference value and the connection quality value, wherein the selection value is the sum of the weighted value of the preference value and the weighted value of the connection quality value, and the sum of the weighted value of the preference value and the weighted value of the connection quality value is 1, as in the above embodiment, the preference value can be determined based on the bandwidth requirement, the speed requirement, the access time duration requirement and the like when the device requests connection, for example, the bandwidth requirement and the speed requirement of the device can be better satisfied, the preference value is higher, so that the device can obtain a larger benefit after being connected to the wireless communication device, the device can operate with higher efficiency, the connection quality generally indicates whether the wireless communication device can perform stable connection with the device, for example, when the wireless communication device is farther away from the device and has a wall or the like in the middle, generally, a signal received by a device is weakened, but in some cases, the signal weakening can cause that the device and a wireless communication device cannot perform stable signal transmission, so that the connection quality is poor, and in some cases, the signal can still maintain stable signal transmission even though the signal is weak, at this time, the connection quality is good, the connection quality and a preference value jointly influence the operation condition of the device after the device is connected with the wireless communication device, in some scenarios, multiple wireless communication devices are provided, wherein one wireless communication device has high signal transmission power and strong signal penetration capability, even if a wall block exists, the signal can reach a far transmission distance, can be connected with far-away internet-of-things devices and provide good connection quality, and the signal of the other wireless communication device does not have strong penetration capability but can provide a large bandwidth, and after the equipment is connected, a higher network speed can be provided, but when the equipment is actually connected with the wireless communication device, the requirements on bandwidth and network speed are higher, and the operation condition of the equipment cannot be actually influenced by weaker signal strength, so that the wireless communication device with stronger signal and better connection quality is not required to be connected.
In an optional embodiment of the present invention, the operation control method of the wireless communication apparatus in the ultra-dense heterogeneous network further includes:
acquiring a request rate when the equipment to be connected requests connection, and determining a maximum rate which is suitable for being distributed to the equipment to be connected by the wireless communication device;
determining the preference value based on the requested rate and the maximum rate.
In the above embodiment, the preference value may be determined based on the bandwidth requirement, the rate requirement, the access time duration requirement, and the like when the device requests connection, in an optional embodiment of the present invention, when the preference value is determined, the requested rate when the device to be connected requests connection is obtained, and in general, the maximum rate that the wireless communication apparatus can allocate to the device to be connected can be obtained, so that the maximum rate is compared with the requested rate to determine the preference value, in a specific embodiment, the difference between the maximum rate and the requested rate and the size of the maximum rate and the requested rate can be determined to determine the preference value, if the maximum rate is greater than the requested rate, the wireless communication apparatus can meet the maximum speed requirement of the device to be connected, and the difference between the maximum rate and the requested rate is small, that is, the difference is small, at this moment, after the wireless communication device is connected with the equipment to be connected, the allocation of the bandwidth rate can be reasonable, so that the preference value is large, and the preference value with a large specific numerical value can be determined to be used as an evaluation standard when the wireless communication device is in matched connection with the equipment to be connected. In other embodiments, when the preference value is determined based on the access time duration requirement and the like, the preference value can be calculated in a weighted manner according to the matching condition of the access time of the to-be-connected device and the wireless communication device and the rate matching condition, so that the preference value is determined, the matching connection of the wireless communication device and the to-be-connected device is more reasonable, the power consumption/power of the wireless communication device is more reasonably distributed, the energy consumption is reduced, and the connection efficiency is improved.
In an optional embodiment of the present invention, the operation control method of the wireless communication apparatus in the ultra-dense heterogeneous network further includes:
obtaining the distance and connection quality between the equipment to be connected and the heterogeneous group;
and determining the pre-connection heterogeneous group according to the distance and the connection quality, and/or determining other heterogeneous groups for connecting with the equipment to be connected according to the distance and the connection quality.
In this embodiment, when there is a device to be connected to the ultra-dense heterogeneous network, the distance and connection quality between each heterogeneous group and the device to be connected are obtained, and an appropriate pre-connection heterogeneous group is allocated to the device to be connected for network connection through the distance and connection quality, so as to ensure the efficiency of network connection and the communication quality, as described above, the connection quality generally indicates whether the wireless communication apparatus can perform stable connection with the device, for example, when the wireless communication apparatus is far away from the device and has a wall or other obstruction in the middle, the signal received by the device is usually weakened, but in some cases, the signal weakening may cause the device and the wireless communication apparatus to fail to perform stable signal transmission, so that the connection quality is poor, and in some cases, the signal is weak, but the signal can still be stably transmitted, and at this time, the connection quality is good, the distance between the heterogeneous group and the equipment to be connected can represent the signal strength provided by the wireless communication device in the heterogeneous group to the equipment to be connected, under the normal condition, the wireless communication device in the heterogeneous group with the shorter distance and the higher connection quality is preferentially selected to be connected with the equipment to be connected, so that the communication quality and the communication efficiency of the equipment are ensured, the fluctuation of network connection caused by obstruction is avoided, and when the connection distance and the connection quality cannot be met together, the wireless communication device with the better connection quality or the wireless communication device with the shorter connection distance can be preferentially selected to be connected with the equipment, so that the connection and the operation of the equipment are ensured to be more stable. In addition, when the estimated utility value is determined to judge that the wireless communication device of the pre-connection heterogeneous group is not suitable for being connected with the device to be connected, other heterogeneous groups connected with the device to be connected can be determined again through the distance and the connection quality, so that the communication quality and the communication efficiency are ensured.

According to the access quantity and the access load of the equipment in the ultra-dense heterogeneous network, the peak time and the valley time of the equipment access can be determined, namely the peak time and the valley time of the equipment access, in the peak time of the equipment access, the equipment access is more, the load is larger, and according to the distribution of the wireless communication devices, under the normal condition, each wireless communication device is connected with the equipment, so that the mode of shutting down the wireless communication device is difficult to select so as to reduce the whole power consumption. In this embodiment, the access peak time of the device in a preset time period can be reasonably determined through the access number and the access load of the device in a plurality of preset time periods through the ultra-dense heterogeneous network, for example, the access peak time of the device in each day is determined, and the load condition of each wireless communication device in the access peak time of the device is determined according to the predicted access estimation data, so as to estimate the load of the wireless communication device in the access peak time of the device, it can be understood that, in the access peak time of the device, although the whole load of the wireless communication device is higher, there may be a situation that part of the wireless communication devices are extremely high, and part of the wireless communication devices are low, therefore, in this embodiment, by estimating the load condition of each wireless communication device, a power limit mode is set for the wireless communication devices according with the preset load condition, for example, a preset power is set, the operating power of the wireless communication device is limited, and the operating power of the wireless communication device is prevented from reaching or exceeding the preset power, so that the operating power of the equipment in the access peak period is reduced, the load is reduced, and the energy consumption is reduced.

In addition, in the period of the equipment accessing to the low valley, because the access equipment is less, the dormancy control can be adopted for each wireless communication device in the period of the equipment accessing to the low valley, so as to improve the service life of the wireless communication device.
To sum up, in a specific embodiment of the present invention, when the ultra-dense heterogeneous network receives an access request instruction of a device, a pre-connection heterogeneous group with a short distance and a good connection quality can be allocated to the device to be connected according to the distance between the device to be connected and each heterogeneous group in the ultra-dense heterogeneous network and the connection quality, so as to pair the wireless communication apparatus in the pre-connection heterogeneous group with the device to be connected and determine whether connection can be performed, specifically, when the device to be connected and the wireless communication apparatus in the pre-connection heterogeneous group perform connection pairing determination, a determination is performed based on the predicted utility value of the wireless communication apparatus corresponding to the device to be connected, when the predicted utility value of the wireless communication apparatus meets the requirement, the wireless communication apparatus is connected with the device to be connected, when the predicted utility value meets the requirement, it is sequentially determined whether the predicted utility values of other wireless communication apparatuses in the pre-connection heterogeneous group meet the requirement, the method ensures that the equipment to be connected is preferentially connected with the wireless communication devices in the pre-connection heterogeneous group for distribution, so as to improve the communication quality and the operation efficiency of the connected equipment, wherein the estimated utility value is determined based on the income of the connected equipment after the equipment is connected with the wireless communication devices and the cost, such as energy consumption, of the connected equipment after the equipment is connected with the wireless communication devices, and when the estimated utility value is used for determining the connection condition of the equipment, the overall operation condition of the connected equipment and the connected equipment can be measured, thereby being beneficial to the maximization of the connection efficiency of the connected equipment and the reduction of the energy consumption of the operation of the wireless communication devices.
When the estimated utility values of all the wireless communication devices in the pre-connection heterogeneous group do not meet the connection requirements of the devices to be connected, the wireless communication devices are selected from other heterogeneous groups to be connected, and the selection values of the devices to be connected to the wireless communication devices are specifically adopted as evaluation criteria, wherein the selection values are determined based on the preference values of the devices to the wireless communication devices and the connection quality of the devices to be connected to the wireless communication devices, so that the devices to be connected and the wireless communication devices can have high matching degree, and the devices to be connected can obtain high connection operation efficiency under the condition that the connection quality reaches the standard.
When the heterogeneous groups in the ultra-dense heterogeneous network work for a certain time, the access situations of the wireless communication devices in each heterogeneous group, such as the access number and the access time period of the wireless communication devices, have a certain rule, so that access estimation data for estimating the future access situation of the wireless communication devices can be generated by storing the access number and the access time period of the wireless communication devices, the future operation situations of each wireless communication device can be estimated according to the access estimation data, and the operation state of the wireless communication devices can be regulated and controlled, such as the wireless communication devices are turned off in a certain time period or the operation power of the wireless communication devices is reduced, so that energy is saved and consumption is reduced. Specifically, the number of the ultra-dense heterogeneous network connection devices and the operation load condition can be analyzed to determine the peak time and the valley time of the ultra-dense heterogeneous network connection devices, the operation power of some devices can be limited in the peak time, for example, it is determined that some wireless communication devices may only be connected with fewer devices in the peak time according to the access estimation data, at this time, the maximum power of the wireless communication devices is limited, some wireless communication devices can be turned off in the valley time to reduce the energy consumption, and in the valley time, due to the fact that the number of the connection devices is small, each wireless communication device can be cyclically dormant in the valley time to gradually turn off and regulate each wireless communication device, so that the operation life of the wireless communication device is prolonged. When the wireless communication device is closed or the operating power of the wireless communication device is limited, when new equipment to be connected is required to be connected, the equipment to be connected can be redistributed and connected according to the communication quality, so that the connection between the equipment and the wireless communication device can be reasonably distributed and regulated, the equipment can be ensured to operate with higher efficiency, and the operating power of the wireless communication device can be reasonably reduced.
The invention also provides an operation control device of the wireless communication device of the ultra-dense heterogeneous network, which comprises a memory, a processor and a computer program which is stored on the memory and can be operated on the processor, and when the processor executes the computer program, the operation control method of the wireless communication device of the ultra-dense heterogeneous network is realized so as to achieve the beneficial effects of the invention.
