It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1 is a flowchart of a method for determining a communication mode of a ground station according to a first embodiment of the present application, where the method may be performed by a device for determining a communication mode of a ground station, and the device may be implemented in software and/or hardware and specifically configured in a ground network control center.
Referring to the ground station communication mode determining method shown in fig. 1, the method is applied to a client, and specifically comprises the following steps:
s110, receiving a communication request between a source ground station and a target ground station associated with a ground network control center.
The Beidou satellite communication system consists of a communication satellite, a ground network control center and a ground station. The communication satellite may achieve complete coverage of ground stations distributed at different locations. The ground network control center can be a centralized network management controller for managing network access management, communication mode dynamic switching and the like of the ground stations in the corresponding range. The different ground network control centers can communicate by means of satellite communication.
The source ground stations associated with the ground network control center may be ground stations within a corresponding range managed by the ground network control center, where the source ground stations may be used to represent ground stations that send communication requests to the associated ground network control center, i.e., ground stations that send communication data during communication between two ground stations. The target ground station may be a ground station in communication with the source ground station, i.e., a ground station that receives communication data during communication by both ground stations. The target ground station and the source ground station may be associated with the same ground network control center or may be associated with different ground network control centers, which is not particularly limited in the present application.
The communication request may be a request for communication connection sent by the source ground station to its associated ground network control center, and may be used to instruct the ground network control center to select a target communication mode for the source ground station. By way of example, the communication request may include the target ground station, the time slot, and the amount of communication data corresponding to the time slot, etc.
S120, in response to the communication request, selecting a target communication mode from candidate communication modes, wherein the candidate communication modes comprise satellite communication and carrier communication.
After receiving the communication request of the source ground station, the ground network control center associated with the source ground station responds to the communication request, namely, a target communication mode is selected for the communication between the source ground station and the target ground station. The candidate communication mode is a mode in which communication between the ground stations is possible. By way of example, candidate communication modes may include satellite communications, carrier communications, and so forth. The target communication mode is a communication mode selected from the candidate communication modes for the present communication.
Specifically, the ground network control center may select the target communication mode according to communication parameters in the historical communication records of the source ground station and the target ground station. The communication parameter may be, for example, a parameter related to a packet loss rate. Specifically, the larger the packet loss rate is, the worse the reliability of communication, so that the probability of selecting a corresponding communication mode can be reduced, so as to improve the reliability of communication. The communication parameter may also be a parameter related to the number of communications, for example. Specifically, the more the number of communications, the higher the frequency of selecting such a communication scheme for communication, the fewer the number of other communication schemes, that is, the lower the utilization rate of other communication schemes, and in order to fully utilize each candidate communication scheme, the probability of selecting the corresponding communication scheme may be reduced to fully utilize each candidate communication scheme.
And S130, transmitting the target communication mode to the source ground station, and indicating the source ground station to communicate with the target ground station by adopting the target communication mode.
The ground network control center transmits the target communication mode to the source ground station after selecting the target communication mode from the candidate communication modes. And after the source ground station receives the target communication mode, the source ground station adopts the target communication mode to communicate with the target ground station, so that information interaction is completed.
In the prior art, communication of ground stations in a Beidou satellite system is mainly realized through a satellite communication mode. The communication between the ground stations is realized by data forwarding through satellites, so that the ground stations cannot directly communicate, partial loss of transmission data possibly occurs, the high reliability requirement of partial service in the power communication network cannot be met, and the problem of low data transmission reliability of the power communication network is caused
The networking technology of the power communication network is an effective method for solving the problems at present. Networking technology is a practical means for ground stations to make communication mode selections. At present, networking planning of the Beidou satellite network mainly relies on manual configuration by operators, so that the problems of large workload and error prone performance exist, and along with the increasing of the number of ground stations and the increasing of the communication demand, reasonable distribution of power communication network resources and effective selection of communication modes cannot be realized.
According to the technical scheme, the ground control center responds to the communication request of the source ground station by receiving the communication request between the source ground station and the target ground station which are associated with the ground control center, selects a target communication mode from candidate communication modes, sends the target communication mode to the source ground station, and indicates the source ground station to communicate with the target ground station by adopting the target communication mode. The candidate communication modes comprise satellite communication and carrier communication, and the ground stations can communicate in one of the candidate communication modes according to requirements, so that the communication modes among the ground stations are enriched. When one of the candidate communication modes has low reliability, another candidate communication mode with high reliability can be selected as the target communication mode, so that the reliability of communication between the ground stations can be improved. Meanwhile, the whole process of selecting the target communication mode does not need to be manually participated, so that the target communication mode with high reliability can be effectively selected while the labor cost is reduced, and the reliability of communication is further improved. Therefore, through the technical scheme of the application, the problem of low reliability of data transmission between the ground stations through satellite communication is solved, and the effect of improving the communication reliability between the ground stations is achieved.

s210, receiving a communication request between a source ground station and a target ground station associated with a ground network control center.
S220, acquiring historical communication parameters between the source ground station and the target ground station.
The historical communication parameters are relevant parameters in the historical communication process between the source ground station and the target ground station and are used for determining the target communication mode. By way of example, the historical communication parameters may include an average communication performance score and a number of communications. The ground network control center obtains the historical communication parameters corresponding to the source ground station and the target ground station from the historical communication record.
S230, determining scores of the corresponding candidate communication modes according to the historical communication parameters of the candidate communication modes.
According to the historical communication parameters of each candidate communication mode, the communication reliability of each candidate communication mode can be determined, so that the reliability of the communication at the time is ensured; and determining the selected balance of each candidate communication mode to fully utilize each candidate communication mode. For example, the likelihood of selecting each candidate communication mode may be scored by integrating the historical communication parameters of each candidate communication mode to select the best target communication mode.

The average communication performance score may be an average of the communication reliability scores during the historical communication for representing the reliability level of each candidate communication mode during the historical communication. For example, the average communication performance score may be determined from the packet loss rate in the historical communications. The number of communications may be a selected number of times during the history of communications and may be used to indicate the sufficiency of use in the history of communications for each candidate communication mode.
The communication performance score may be a score for the communication performance of each candidate communication mode during the historical communication process, and is used to characterize the communication performance of each candidate communication mode. Specifically, the greater the value of the communication performance score, the greater the likelihood of being selected as the target communication mode. For example, the reciprocal of the average communication performance score may be taken as the communication performance score.
The equalization score may be a score for the utilization of each candidate communication pattern in the historical communication process that characterizes the equalization with which each candidate communication pattern was utilized. Specifically, the greater the value of the equalization score, the greater the likelihood of being selected as the target communication mode. For example, the equalization score may be determined based on the number of communications.
The scores for each candidate communication mode are determined based on the communication performance scores and/or the equalization scores using a confidence interval upper bound algorithm for reliability awareness. For example, the sum of the communication performance score and the equalization score may be taken as the score for each candidate communication mode.
The reliability of data transmission of the respective candidate communication modes may be measured by determining the communication performance score of the respective candidate communication mode based on the average communication performance score of each candidate communication mode. And determining the balance score of the corresponding candidate communication mode according to the communication times of the candidate communication modes, and measuring the balance of the candidate communication modes. According to the communication performance score and/or the balance score, the score of each candidate communication mode is determined, the reliability and the utilization efficiency of the candidate communication mode can be comprehensively considered, the communication reliability is guaranteed, meanwhile, each candidate communication mode is fully utilized, the communication reliability and the utilization efficiency of each candidate communication mode can be improved, and the resource waste caused by excessive use of one candidate communication mode is avoided.
In an alternative embodiment, determining the communication performance score for each candidate communication mode based on the average communication performance score for the respective candidate communication mode comprises: and taking the reciprocal of the average communication performance score as the communication performance score corresponding to each candidate communication mode.
The average communication performance score comprises the reciprocal of the packet loss rate, and the reciprocal of the average communication performance score is used as the communication performance score corresponding to each candidate communication mode because the smaller the packet loss rate is, the better the communication performance is.
The ground network control center covered by the communication satellite can be represented by a set as f= { F 1 ,...,f i ,...,f I }. Wherein f 1 And f I F is respectively a first ground network control center and a last ground network control center i I=2, 3..i-1 represents the I-th ground network control center, there are I ground network control centers in total.

The candidate communication mode set may be represented as c= { C 1 ,C 2 }. Wherein C is 1 And C 2 Satellite communications and carrier communications, respectively.

Wherein, the liquid crystal display device comprises a liquid crystal display device,representing the ground network control center f m Is the j-th ground station of (2); f (f) m Representing an mth ground network control center;scoring the average communication performance.
The reciprocal of the average communication performance score is used as the communication performance score corresponding to each candidate communication mode, so that the communication performance score obtained by the candidate communication mode with smaller packet loss rate in the communication process is higher. And the inverse relation between the packet loss rate and the communication performance score is ensured, and the accuracy of the communication performance score is ensured.
In an alternative embodiment, determining the equalization score for each candidate communication mode based on the number of communications in each candidate communication mode includes: determining confidence predicted values of the corresponding candidate communication modes according to the communication times of the candidate communication modes; and taking the confidence predicted value as an equalization score of the corresponding candidate communication mode.

Meanwhile, the load of each candidate communication mode can be balanced, so that the communication performance is prevented from being reduced when the load of one candidate communication mode is overlarge, each candidate communication mode is fully utilized, and the communication reliability is ensured.
