And N is an integer greater than 0, and the N second mobile terminals form a determined terminal set.
The specific implementation process of step 402 may be: referring to fig. 5, fig. 5 is a flowchart illustrating an implementation manner of determining a terminal set in the embodiment of the present application. The method comprises the following steps:
The determination of the set of terminals is not taken into account, i.e. not involved, for mobile terminals which cannot communicate with the base station.
Suppose that the current mobile terminal a cannot communicate with the base station, and there are a mobile terminal B, a mobile terminal C, a mobile terminal D, a mobile terminal E, and a mobile terminal F in the mesh network.
If the mobile terminal F cannot communicate with the base station, the candidate set includes the following mobile terminals:
mobile terminal B, mobile terminal C, mobile terminal D, mobile terminal E.
When the communication quality parameters are: when the RSRP drop rate and the remaining network speed are high, the specific implementation of determining the mobile terminal with the highest communication quality in the current candidate set according to the communication quality parameters of each mobile terminal in this step is as follows:
if the mobile terminal with the RSRP disconnection rate smaller than 1 is determined to exist, determining that the communication quality of the mobile terminal with the maximum residual network speed is the highest;
that is, if the RSRP drop rate of a mobile terminal is smaller than the preset threshold, it is considered that the communication quality reflected based on the RSRP drop rate is consistent, and the communication quality of a mobile terminal is measured by the remaining network speed, and the larger the remaining network speed is, it is considered that the communication quality is higher.
If the mobile terminal with the RSRP disconnection rate smaller than the preset threshold value does not exist, determining that the communication quality of the mobile terminal with the minimum RSRP disconnection rate is the highest;
that is, if the RSRP drop rate of a mobile terminal is not less than 1, the communication quality of a mobile terminal is measured by the RSRP drop rate regardless of the network speed of the mobile terminal, and the smaller the RSRP drop rate is, the higher the communication quality is.
Assuming that the RSRP drop rates of the mobile terminal B and the mobile terminal C are both less than 1, and the remaining network speed of the mobile terminal B is greater than the remaining network speed of the mobile terminal C, the RSRP drop rates of the mobile terminal D and the mobile terminal E are both greater than 1, and the RSRP drop rate of the mobile terminal D is less than the RSRP drop rate of the mobile terminal E, the RSRP drop rates are sequentially: mobile terminal B, mobile terminal C, mobile terminal D, mobile terminal E.
In this embodiment, the following preset conditions are taken as examples:
the sum of the remaining network speeds of the N second mobile terminals is not less than the network speed required for data transmission between the first mobile terminal and the base station, and the sum of the remaining network speeds of the N-1 second mobile terminals is less than the network speed required for data transmission between the first mobile terminal and the base station.
And when the remaining network speed of the mobile terminal B is lower than the network speed required by the mobile terminal A, continuing to select the mobile terminal (the mobile terminal C) with the highest communication quality in the candidate set (the mobile terminal C, the mobile terminal D and the mobile terminal E) for deleting the mobile terminal B, and so on until no mobile terminal exists in the candidate set or the sum of the remaining network speeds of all the mobile terminals in the current terminal set is larger than the network speed required by data transmission between the mobile terminal and the base station, and ending the determination of the terminal set.
And 505, taking the current terminal set as the determined terminal set.
At this point, the determination of the terminal set is completed.
In the embodiment of the invention, when a first mobile terminal in the mesh network cannot communicate with a base station, other mobile terminals are selected as transfer to help the first mobile terminal to communicate, the first N second mobile terminals with higher communication quality are selected, and the sum of the remaining network speeds of the N second mobile terminals meets the preset condition for data transmission between the first mobile terminal and the base station, so that the N second mobile terminals can assist the first mobile terminal to communicate, and the network speed requirement of the first mobile terminal is met, namely the communication quality of a single mobile terminal is better improved, and further the communication quality and the resource utilization rate of the mobile terminals in the whole mesh network are improved.

if a mobile terminal with a reference signal receiving power drop rate smaller than a preset threshold exists in all the obtained mobile terminals, determining that the reference signal receiving power drop rate is smaller than the preset threshold, and the mobile terminal with the largest residual network speed has the highest quality, and determining that the mobile terminal is the second mobile terminal;
if no mobile terminal with the reference signal receiving power drop rate smaller than the preset threshold value exists in all the obtained mobile terminals, the mobile terminal with the minimum reference signal receiving power drop rate is the mobile terminal with the highest communication quality, and the mobile terminal is determined to be the second mobile terminal.
In the embodiment, only one second mobile terminal with the highest communication quality is selected, and the second mobile terminal is used for communicating with the mobile terminal which cannot communicate with the base station, so that the mobile terminal which cannot communicate with the base station can communicate with the base station by using the resources of the mesh network under the condition that the mobile terminals in the mesh network communicate infrequently, and meanwhile, the resource utilization rate of the mesh network is improved.
In the first to fourth embodiments, if the second mobile terminal in the determined terminal set cannot directly communicate with the first mobile terminal, the second mobile terminal and the first mobile terminal can communicate with each other, and here, the mobile terminal that enables communication between the second mobile terminal and the first mobile terminal may be referred to as an intermediate mobile terminal, and may be one or a plurality of mobile terminals.
If the mobile terminal a cannot communicate with the base station, the determined terminal set includes the mobile terminal C, but the mobile terminal C cannot directly communicate with the mobile terminal a, for example, due to distance, and the mobile terminal a and the mobile terminal C can both communicate with the mobile terminal B, the mobile terminal a communicates with the mobile terminal C through the mobile terminal B, and then communicates with the base station through the mobile terminal C.
