s1: the terminal executes the activation operation and writes a network number;
s2: the terminal periodically searches for the pilot broadcast broadcasted by the base station in the range, the broadcasting cycle time of the base station is 1 second, and the ratio of the transmission time of the pilot broadcast in the broadcasting cycle time is not more than 1%. The terminal searches for base stations with the same network number in the pilot broadcast, tries to establish communication connection with the base station corresponding to the pilot broadcast, and as the network numbers of the base stations in the local area network are the same, the terminal does not try to communicate with the base stations which do not belong to the network, stops searching for other pilot broadcasts, and simultaneously judges the registered network access information initiated by the terminal by the base stations in an edge calculation mode, and immediately gives a response if the judgment is passed; if the pilot broadcast to the matching is not searched, the terminal continues to search periodically; meanwhile, the registration information of the terminal is pushed to the network for final judgment, if the terminal can be finally judged to be in the network, the terminal and the base station continue to keep communication connection, if the terminal can not be in the network, the terminal receives failure notification next time, and continues the guide broadcast broadcasted by the base station in the periodic search range;
s3: after receiving the response given by the base station, the terminal registers for network access and periodically reports the state information and the position information of the terminal; otherwise, continuing the periodic search;
s4: and the terminal executes logout operation and erases the network number, and stops the guide broadcast in the search range. Further, the step S2 includes the following steps:
s5: if the terminal searches a plurality of guide broadcasts with the same network number and capable of being matched, the communication quality of the searched guide broadcasts is judged first, and a base station corresponding to the guide broadcast with the optimal communication quality is selected from the guide broadcasts to try to establish communication connection with the base station.
Further, the step S3 is followed by the following steps:
s6: the terminal judges whether the value of the communication quality of the current communication connection is in the range value of the grade C (the communication is medium, the communication failure risk exists at low probability) in real time, if so, the pre-search is started, and the specific implementation method of the pre-search is as follows:
1) setting the interval base number of terminal searching base station as N, and the communication quality of current communication connection as QC1Represents;
2) the terminal judges the current communication quality in real time to determine the cycle time of pre-search: if Q isC1If the value of (1) is within the range of A or B, then the pilot broadcast within the range is not searched; if Q isC1If the value of (1) is within the range of communication quality grade C, pre-searching for the pilot broadcast once every N; if Q isC1The value of (2) is in the range of communication quality grade D, and the pilot broadcast is pre-searched once every N/2^ 1; if Q isC1The value of (c) is within the range of the communication quality level E, the pilot broadcast is pre-searched every N/2^2, the worse the communication quality is, the shorter the interval is, after each pre-search is finished, the terminal records the communication quality Q for the pilot broadcast of the last pre-searchC2Typically, the level of communication quality can be refined according to specific situations, and a more refined solution is set;
3) when the terminal and the current base station still keep communication, pre-switching is carried out according to the following strategies: when Q isC1When the value is within the range of the communication quality grades A and B, the pilot broadcast within the range is not searched; when Q isC1When the value is in the threshold range of the communication quality grade C, Q isC1Value ratio QC1The values are compared, if QC1Value ratio QC1If the value is at least 2 grades larger, the base station is directly switched, and the network access is registered to enter QC2The corresponding base station realizes the seamless switching of the base station; if not, triggering the pre-search again.
Wherein the quality of communication QcThe communication quality is classified into five levels of ABCDE in advance (as shown in table 1).
Table 1 communication quality rating table
| QCValue taking | Quality grade | Means of |
| 0.8＜Qc≤1 | A | Excellent communication without switching |
| 0.6＜Qc＜0.8 | B | Good communication without switching |
| 0.4＜QC≤0.6 | C | Moderate and low probability of communication failure |
| 0.2＜QC≤0.4 | D | Poor communication, medium probability with communication failure risk |
| 0＜QC≤0.2 | E | Poor communication and high probability of communication failure risk |
The communication quality is determined by the signal strength in the pilot broadcast and the busy degree of the base station, and the calculation formula of the communication quality is as follows:
wherein Q isCFor the current communication quality, C0The current base station telephone traffic, c is the upper limit of the base station telephone traffic, R is the current communication signal strength between the terminal and the base station, S is the communication sensitivity, K is the communication sensitivityCRTo normalize the factor, so that QCThe value range of (1) is 0-1.
Further, the guided broadcast is that the base station periodically transmits broadcast signals outwards at an appointed frequency point, and the guided broadcast comprises a base station number, a network number, a communication frequency point, a modulation mode, transmission power and a base station busy degree.
