Embodiment 1
[0053] figure 1 It is a flowchart of a method for interoperability between different systems in a wireless scenario according to an embodiment of the present invention. Such as figure 1 As shown, this embodiment includes:
[0054] Step S102: Obtain the drive test signal of the road section to be optimized;
[0055] Step S104: When the drive test signal decays from the starting point to the critical call drop point within the preset time period, or when the field strength of the drive test signal is lower than the preset field strength value or the coverage exceeds the coverage of automatic adaptation , or when the degree of interference in the drive test signal exceeds the preset interference value, set the interoperability parameters.
[0056] In this embodiment, aiming at the defect that the scene corresponding to the reselection parameter is too rough in the prior art, and the selection of the reselection parameter does not correspond to the specific scene, the scene of ...

[0076] In this embodiment, on the basis of the first embodiment, the setting of reselection parameters from 3G to 2G in different scenarios will be focused on. Table 1 is a mapping table of 3G to 2G reselection parameters and scenarios in the present invention. As shown in Table 1:

[0080] In Table 1, X is the fading time, Fast_fading is the fast fading time threshold, and Slow_fading is the slow fading time threshold. In the TD-SCDMA extremely fast fading sub-scenario, the TD-SCDMA signal rapidly fades with space, such as highways and railway sites with severe fading. Because the TD signal will fade to the critical drop point in a very short period of time, which may be less than 3S, it is necessary to allow the terminal to occupy the G network more quickly, so as to avoid unconnected and call dropped events, which will affect user perception.

Embodiment 3
[0104] The values of the reselection parameters from 2G to 3G are different in different scenarios. In each scenario, a large-scale test needs to be organized, and the test results are finally mapped to the scenario.
[0105] When the 3G signal is good, the terminal should try to stay on the 3G network. To understand this concept in reverse, that is, when the 3G network is not good, the terminal should stay on the 3G network as little as possible. According to the scene identification method, in fact, the existence of a scene in a cell can represent the 3G network coverage of this cell, which is problematic. For these scenarios, the reselection parameters can be used on the 2G side to make it difficult for the terminal to select these 3G cells with scenarios. Then, considering the fluctuation of field strength GAP and the probability of ping-pong handover, the reselection parameters from 2G to 3G are automatically Matching is done.
[0106] In this implementation, the key ...
