It should be noted that FIG. 1 is only an exemplary architecture diagram. In addition to the functional units or devices shown in FIG. 1 , the network architecture may further include other functional units or devices, which are not limited in this embodiment of the present application.

An embodiment of the present application provides a method for establishing an ad hoc network, which can be applied to the communication network shown in FIG. 1 . As shown in FIG. 2 , the method includes S101-S106.

S101. The mobile device sends at least one piece of location information to a network device.

The location information may specifically be latitude and longitude information or the identity of a base station or a cell accessed by the mobile device, and the like.

It should be noted that the mobile device has a positioning function, and the positioning function can be specifically realized by the existing global positioning system (Global Positioning System, GPS) positioning technology, or the mobile device uses the WiFi technology to realize the positioning function. No restrictions apply.

During the movement of the mobile device, the mobile device acquires location information in real time, and reports the acquired location information to the network device in real time.

Exemplarily, the mobile device and the network device are connected through the 5G network, the relay module of the mobile device can amplify the wireless signal, and send its own location information to the network device in real time through the 5G network to facilitate the network device to the mobile device. Real-time monitoring of equipment to obtain location information.

S102. The network device determines the movement track of the mobile device according to the at least one piece of location information.

The movement track of the mobile device is a track formed by the current location information acquired in real time during the movement of the mobile device.

Optionally, in the process of determining the movement track of the mobile device, the time interval for the mobile device to report the location information and the time interval for the network device to determine the movement track of the mobile device according to the reported location information may be set according to the actual situation. Exemplarily, the mobile device reports the location information every 1 minute, then the network device can determine the movement trajectory of the mobile device every 1 hour, that is, the network device samples 60 pieces of location information of the mobile device every 1 hour to determine the 1 hour. movement trajectory.

Optionally, in the specific process of determining the movement trajectory of the mobile device, the mobile device reports at least one location information to the network device in real time, when the network device samples multiple location information of the mobile device within a period of time, for example: 60 locations. information, the network device first forms the movement trajectory of the mobile device according to the sampled 60 position information, and then judges whether there is any position information that deviates from the trajectory in the 60 position information.

Afterwards, the network device determines the active area of the mobile device according to the trajectory formed by the valid location information, such as longitude and latitude information. The above-mentioned deviation track is the location information that is obviously discrete from other valid location information.

S103. The network device determines whether the mobile device is located in a preset area according to the movement track of the mobile device.

Taking the 5G network as an example, the preset area referred to in S103 is the area where the high-frequency 5G signal is relatively weak, that is, the high-frequency signal strength is less than the preset strength threshold, and the preset strength threshold can be set according to the actual situation. .

The network device compares the obtained movement trajectory of the mobile device with the pre-stored network coverage heat map in the GIS. If the 5G signal at the location of the mobile device is determined to be less than the preset threshold, the network device determines that the mobile device is in the preset position. In the area, the following step S104 is performed.

S104. The network device sends a first instruction to the mobile device.

Optionally, when multiple mobile devices are simultaneously in the same 5G network hole edge area, the mobile device scheduling module in the network device will control and schedule the above-mentioned multiple mobile devices. For example, the mobile device scheduling module selects some mobile devices from multiple mobile devices and sends a first instruction to them, instructing them to enable the relay function.

For another example, the mobile device scheduling module may select a mobile device closest to the edge of the 5G network hole from multiple mobile devices to send the first instruction.

It has the functions of amplifying signals, compensating for signal attenuation, and supporting long-distance communication.

Optionally, after the mobile device receives the first instruction issued by the network device, the mobile device automatically enables the relay function of the relay module. Or, after the mobile device receives the first instruction issued by the network device, the relay module outputs a prompt message for enabling the relay function in the display module by scheduling other modules of the mobile device, such as the display module, to prompt the user to enable the relay Function.

After the mobile device completes S105, while the mobile device continues to move, the mobile device and the network device continue to perform the above process, that is, to determine whether the mobile device is at the edge of network coverage, and when it is determined that the mobile device is not at the edge of the 5G network coverage, That is, the mobile device is located in an area with good 5G network signal coverage, and step S106 is performed.

In the method for establishing an ad hoc network provided by the present application, the network device determines the movement track of the mobile device by receiving at least one piece of location information reported by the mobile device. If the movement track of the mobile device is located in an area with poor network signals, the network device sends a first instruction to the mobile device to instruct the mobile device to enable the relay function and join the ad hoc network, thereby making up for the high frequency band hole in the network to reduce network High frequency band coverage holes.

It should be noted that in the process of using a mobile device to form an ad hoc network, the relay signal formed by the mobile device may have some influences such as signal interference on the network. , therefore, the number of mobile devices held by the user should be minimized. Based on this, an embodiment of the present application also provides a method for reducing the number of mobile devices used. The method includes the following steps:

1. The operator issues an announcement to recruit candidate relay volunteers, that is, mobile device carriers. Preliminary screening of candidate volunteers.

The user equipment can be the user's mobile phone, or the user can carry other devices with positioning functions, that is, As an alternative to determining the movement trajectory in the above S101-S106, other devices with a positioning function carried by the user may also report the user's location information when the network signal strength is high.

Of course, the user equipment may also be the above-mentioned mobile equipment (ie, small base station) with the relay function disabled.

2. The operator obtains the location information of the candidate volunteer user through the network side device, and determines the movement trajectory of the candidate volunteer user.

The operator acquires at least one location information of the candidate volunteer user in real time, determines the movement trajectory of the candidate volunteer user according to the acquired at least one location information, and counts the activity trajectory of the candidate volunteer user for a week.

3. Determine the volunteers, the final mobile device carriers, from the candidate volunteers.

The operator compares the obtained movement trajectories of the candidate volunteer users with the network coverage heat map pre-stored in the GIS module. If the obtained movement trajectories are more repetitive and closer to the network holes, the score will be higher, and the candidate volunteers will be compared. The user's activity track for a week is sorted according to the score from high to low, and volunteers are selected according to the score from high to low.

After the volunteers are selected, a device as shown in the mobile device 102 in FIG. 1 can be distributed to the volunteers, and the volunteers can carry the mobile device to implement S101-S106 described in the embodiments of the present application.

Improve the blinding effect of network holes.

In other embodiments of the present application, the information returned by the mobile device to the network device may also be used to indicate the networking of the subsequent ad hoc network. Exemplarily, the network device obtains the power consumption and the quality of the backhaul signal when the mobile device is in different locations, and determines the signal strength at different locations based on these two parameters. When the power consumption of the mobile device is large and the quality of the backhaul signal is poor , it means that the network signal at the location where the mobile device is located is poor. Subsequently, the operator can perform network optimization for the network deployment at this location, thereby improving network performance.
