here, the first parameter may specifically be a synchronization sequence energy; after obtaining the N first different information, the first terminal analyzes each piece of synchronization information to obtain N synchronization sequence energies.
Step 103: and updating the multi-hop level of the first terminal according to the N first parameters.
Here, the first terminal updates its own multi-hop level according to the magnitude of one or more of the N synchronization sequence energies.
Therefore, in the embodiment of the invention, other information is not needed, and only the energy of the synchronization sequence of one or more multi-hop levels is needed to be known, the first terminal can update the multi-hop level of the first terminal, so that the multi-hop level can be quickly updated; meanwhile, the synchronization sequence energy value is more accurate because the synchronization sequence energy according to the first terminal is sent by all the synchronization source terminals under each multi-hop level, so that the updating accuracy of the first terminal is improved; in addition, the fast update of the multi-hop level further reduces the homogenization synchronization source and reduces the network energy consumption.

The foregoing steps may serve as a further explanation of the method for monitoring the first synchronization information of each of the N multi-hop levels to obtain the N first synchronization information in the present invention.
Step 202: analyzing the n pieces of first synchronization information to obtain n pieces of first parameters corresponding to the n pieces of first synchronization information;
here, the first parameter may specifically be a synchronization sequence energy; after n pieces of first synchronization information are monitored, analyzing each piece of first synchronization information to obtain n pieces of synchronization sequence energy.

Here, in the analyzed n synchronization sequence energies, the first terminal first determines whether there is a synchronization sequence energy exceeding a first predetermined threshold, and when it is determined that there is a synchronization sequence energy exceeding the first predetermined threshold, determines that a multi-hop level corresponding to the synchronization sequence energy exceeding the first predetermined threshold is a first target level, and adds 1 to the first target level and a pre-configured counter, that is, determines, every time it is determined that there is a synchronization sequence energy exceeding the first predetermined threshold in the n monitored synchronization sequence energies, a multi-hop level corresponding to the synchronization sequence energy, and adds 1 to the counter configured for the multi-hop level.
The first terminal monitors first synchronization information under a first target level continuously or discontinuously for M times to obtain M pieces of first synchronization information, and analyzes the M pieces of first synchronization information to obtain M pieces of synchronization sequence energy corresponding to the first target level. And in the M synchronous sequence energies, judging whether M synchronous sequence energies which all exceed a first preset threshold exist, namely judging whether the count value of a counter configured at a first target level is larger than or equal to M, and when M synchronous sequence energies which all exceed the first preset threshold exist, namely judging that the count value of the counter configured at the first target level is larger than or equal to M, cancelling the identity of a synchronous source terminal by the first terminal and updating the terminal to be an asynchronous source terminal.
Wherein, M is an integer greater than or equal to 0, M is an integer greater than or equal to 0 and less than or equal to M, and the first predetermined threshold value M, M and the like can be flexibly set according to actual use conditions. In this embodiment, the first predetermined threshold may be any one of-70 dBm (decibel milliwatt/volt) to-50 dBm, or [ -70dBm to-50 dBm ]; m can be any positive integer from 2 to 5; m is usually an integer of M/2+1 or more.

determining that there are L multi-hop levels for which m first parameters exceed the first predetermined threshold; selecting a minimum multi-hop level from the L multi-hop levels; the first terminal is synchronized with the synchronization source terminal at the minimum multi-hop level; wherein L is a positive integer.
Here, when there are M synchronization sequence energies exceeding a first predetermined threshold among the M synchronization sequence energies, the first terminal determines that there are L first target levels corresponding to the M synchronization sequence energies exceeding the first predetermined threshold, cancels the synchronization source terminal identity, updates the synchronization source terminal to the non-synchronization source terminal, and synchronizes with the synchronization source terminal at the minimum multi-hop level among the L first target levels.
In a further preferred embodiment of the present invention, the method further comprises:
when the first judgment result and/or the second judgment result show that the first judgment result and/or the second judgment result do not exist, judging whether a first parameter corresponding to the analyzed first synchronization information with the multi-hop level being n-1 exceeds a second preset threshold value or not, and obtaining a third judgment result; when the third judgment result shows that the second preset threshold value is exceeded, the first terminal maintains a multi-hop level n; and when the third judgment result shows that the multi-hop level of the first terminal does not exceed the second preset threshold, updating the multi-hop level of the first terminal according to the first synchronization information of each multi-hop level of n-1 multi-hop levels from the multi-hop level 0 to the multi-hop level n-2.
Wherein, the updating the multi-hop level of the first terminal according to the first synchronization information of each multi-hop level of n-1 multi-hop levels from multi-hop level 0 to multi-hop level n-2 further comprises: extracting a first parameter corresponding to first synchronization information of each multi-hop level of n-1 multi-hop levels under the multi-hop level 0 to the multi-hop level n-2 to obtain n-1 first parameters; judging whether a first parameter exceeding the second preset threshold exists in the n-1 first parameters or not, and obtaining a fourth judgment result; when the fourth judgment result shows that the first parameter exists, determining K multi-hop levels corresponding to the first parameter exceeding the second preset threshold; selecting a minimum multi-hop level p of the K multi-hop levels; updating the multi-hop level of the first terminal to be p + 1; if the fourth judgment result shows that the multi-hop level of the first terminal does not exist, updating the multi-hop level of the first terminal to be the minimum multi-hop level in all multi-hop levels, and if the multi-hop level is updated to be multi-hop level 0; wherein K is a positive integer less than or equal to n-1, and p is an integer greater than or equal to 0 and less than or equal to n-2.
Specifically, when it is determined that there is no synchronization sequence energy exceeding a first predetermined threshold in the n synchronization sequence energies and/or it is determined that there are no M synchronization sequence energies exceeding the first predetermined threshold in the M synchronization sequence energies corresponding to each first target level, extracting synchronization sequence energy corresponding to first synchronization information of a multi-hop level n-1, and determining whether the synchronization sequence energy exceeds a second predetermined threshold;
when the energy of the synchronization sequence is judged to exceed a second preset threshold value, the first terminal does not update the multi-hop level and still maintains the multi-hop level n;

In the above scheme, the second predetermined threshold value can be flexibly set according to the actual use condition. In this embodiment, the second predetermined threshold may be any integer from-90 dBm to-110 dBm, or [ -90dBm, -110dBm ].
Therefore, in the embodiment of the invention, other information is not needed, and only the size of the energy of the synchronization sequence of each multi-hop level in the multi-hop levels 0-n-1 is needed to be known, the first terminal can update the multi-hop level of the first terminal, so that the multi-hop level can be quickly updated; meanwhile, the synchronization sequence energy value is more accurate because the synchronization sequence energy according to the first terminal is sent by all the synchronization source terminals under each multi-hop level, so that the updating accuracy of the first terminal is improved; in addition, the fast update of the multi-hop level further reduces the homogenization synchronization source and reduces the network energy consumption.
The third method embodiment:

FIG. 3 is a schematic flow chart illustrating an implementation of a third embodiment of an information processing method according to the present invention; as shown in fig. 3, the method includes:
step 301: selecting a first time, and not sending first synchronization information at the first time, wherein the first terminal needs to send the first synchronization information at the first time;
here, in the multihop network, a first terminal at the multihop level n needs to send first synchronization information with other synchronization source terminals at the same multihop level under the same allocated resource, and preferably, the first terminal at the multihop level n needs to send the first synchronization information with other synchronization source terminals at the same multihop level at the same allocated time; in this embodiment, when the first terminal monitors the first synchronization information at the multi-hop level n, the first synchronization information is not sent in the time of sending the first synchronization information, and the first synchronization information sent by other synchronization source terminals at the same multi-hop level as the first terminal is monitored.
Step 302: monitoring first synchronization information sent by other multi-hop synchronization source terminals with the level n except the first terminal in a first time;
here, the first terminal listens for first synchronization information transmitted by other synchronization source terminals at the same multi-hop level as the first terminal itself in a first time.
Step 303: analyzing the first synchronization information to obtain a first parameter corresponding to the first synchronization information;
here, the first terminal analyzes the first synchronization information with the multi-hop level n to obtain the synchronization sequence energy of the multi-hop level n.
Step 304: judging whether the first parameter exceeds a third preset threshold value or not, and obtaining a fifth judgment result;
here, it is determined whether the synchronization sequence energy is greater than a third predetermined threshold;
step 305: when the fifth judgment result shows that the third preset threshold is exceeded, the first terminal does not execute a synchronization source function and cancels the multi-hop level, and the first terminal and the synchronization source terminal with the multi-hop level being n are synchronized; and when the fifth judgment result shows that the multi-hop level n is not exceeded by the third preset threshold, the first terminal maintains the multi-hop level n.
When the energy of the synchronization sequence is judged to be larger than a third preset threshold value, it is indicated that more synchronization source terminals exist around the first terminal, the first terminal does not need to have the synchronization source terminal identity any more, the synchronization source terminal identity of the first terminal is cancelled, the first terminal is updated to be an asynchronous source terminal, and the first terminal is synchronized with other synchronization source terminals at a multi-hop level n; and when the energy of the synchronization sequence is judged to be less than or equal to a third preset threshold value, the first terminal continuously maintains the identity of the synchronization source terminal at the multi-hop level n.
Therefore, in the embodiment of the invention, other information is not needed, and the multi-hop level n of the first terminal can be cancelled or maintained only by knowing the energy of the synchronization sequence sent by other synchronization source terminals at the multi-hop level n, so that the identity of the synchronization source terminal is rapidly updated; meanwhile, the synchronization sequence energy value is more accurate because the synchronization sequence energy according to the first terminal is sent by all other synchronization source terminals under the multi-hop level n, so that the updating accuracy rate is improved; in addition, when the number of the synchronization source terminals at the same multi-hop level is large or the distance is short, the synchronization source identity of the first terminal is cancelled in time, so that the homogeneous synchronization sources are reduced, and the network energy consumption is reduced.
