S2: and encrypting the acquired operation data to obtain a communication message.
The data interaction with the communication terminal in the power wireless heterogeneous network is realized through the international standard protocol, and meanwhile, the safety of the power wireless heterogeneous network needs to be met. Aiming at the characteristics that the bandwidth of the power wireless heterogeneous communication network is relatively small and the processing capacity of the wireless terminal is limited, the embodiment adopts a lightweight asymmetric encryption algorithm to encrypt the communication message formed by the operation data. The encryption is completed by the power system server, and specifically comprises the following steps:
taking one point on a preset elliptic curve Ep (a, b) as a base point G, determining a user private key K, and generating a public key K=kG;
Encoding the acquired operation data to a point M on an elliptic curve Ep (a, b) to randomly generate an integer r;
Communication message C 1 and communication message C 2 are obtained by encryption calculation, respectively, wherein C 1＝M+rK,C2 =rg.
The requirements in terms of security, hardware overhead, traffic overhead and computational efficiency are simultaneously met through the improved elliptic encryption algorithm. In elliptic curve systems we can achieve the same security strength as conventional RSA algorithms by using much shorter keys. For example, it is generally believed that 160-bit elliptic curve keys provide security strength comparable to 1024-bit RSA keys, and the use of short keys has the benefits of fast encryption and decryption, energy conservation, bandwidth conservation, and storage space.
S3: and analyzing whether the degradation reason is that the link is at the cell edge or not according to the link degradation condition of the power wireless heterogeneous network by the communication message.
And receiving the communication message C 1 and the communication message C 2, and performing decryption calculation on the communication message C 1 and the communication message C 2 according to the private key k of the user.

And performing quality detection on the decrypted communication message, comparing the operation data in the communication message M with a preset degradation condition, and judging that the link degradation condition occurs if the communication message meets the preset degradation condition.
The reasons for link degradation mainly include that the link of the terminal is at the cell edge, the interference of the frequency band where the link of the terminal is located is too large, and other reasons, and in this embodiment, a processing policy for switching between heterogeneous networks is adopted according to the situation that the link is at the cell edge, which specifically includes: and acquiring uplink and downlink data in the communication message, and acquiring pilot frequency RSCP of a cell where a link is located according to the uplink and downlink data. Pilot RSCP is the signal strength of a pilot channel, and pilot is a direct sequence spread spectrum signal which is not modulated and continuously transmitted by devices such as a base station, a terminal and the like, and provides signal strength comparison for each base station, so that the devices such as the terminal and the like can determine when to switch.
If the pilot frequency RSCP of the cell is lower than a preset threshold, determining that the degradation of the link is caused by the fact that the link is at the edge of the cell. In this embodiment, in order to obtain the pilot RSCP of the cell where the link is located and the pilot RSCP of the neighboring cell, for downlink measurement, the terminal is required to report the operation data while adding the same-frequency measurement result and the different-frequency measurement result, for uplink measurement, after determining that the link is degraded, an internal measurement control message is required to be initiated to the terminal, and the terminal is required to report the same-frequency measurement result and the different-frequency measurement result periodically.
If the pilot RSCP of the cell is not lower than the preset threshold, it is considered that other reasons cause link degradation, and the link rate is selected to be reduced to reduce interference to other users, and intra-cell time slot adjustment is generally performed on the large-rate service portion, which mainly considers that after the large-rate service is adjusted to other time slots, the user in other time slots is also an interference.
S4: and if the link is at the cell edge, adjusting the cell where the link is located.
If the degradation is due to the link being at the cell edge, the cell of the link is handed over. The embodiment realizes cell switching through an HC algorithm, wherein the HC algorithm is used for transferring a link to a new cell to realize handover, thereby ensuring the continuity and the service quality of communication.
And after switching the link to a new cell, re-analyzing the link degradation condition of the power wireless heterogeneous network, namely repeating the step S3, and if the link degradation condition is not improved, reducing the rate of the link.
In addition, the embodiment further includes generating alarm information when a link degradation condition occurs, where the alarm information includes an alarm code, an alarm level, an alarm name, and a service standard name corresponding to the alarm name. The method comprises the steps of carrying out standardized processing on alarm information through a standardized alarm mapping code table constructed in advance to form a communication alarm standard mapping rule applicable to various power distribution and utilization service communication terminals, taking the most main optical fiber communication and wireless communication technology of a power terminal communication access network as an example, forming standard alarm codes and standard names as shown in a table 1, converting the alarm information into standard names and outputting the standard names, and realizing cross-manufacturer, cross-technology system and cross-level state monitoring and alarm of a power production service communication channel, so that the method can be applicable to alarms of different equipment manufacturers.
TABLE 1
The method for generating the alarm information solves the problems that the heterogeneous network is cracked and cannot be monitored in the whole course in the traditional monitoring mode, provides an effective and visual means for monitoring and guaranteeing the state of communication service and positioning and checking faults, and can remarkably improve the operation and maintenance management efficiency of the electric power wireless heterogeneous network.
