Detailed Description
The communication satellite sleep control method in this embodiment may be applied to the space-ground integrated communication network shown in fig. 1, which includes a user terminal, a communication satellite, an operation control center, a core network, and the like. Wherein, the communication satellite operates in space; the user terminal can be a terminal such as a mobile phone held or installed by a ground person or a vehicle, or a special satellite communication terminal; the operation control center and the core network can be arranged on the ground, and can be combined into a whole, the operation control center is responsible for directly communicating and controlling with the communication satellite, and the core network carries out various data processing.
In this embodiment, the communication satellite may also be referred to as a satellite base station.
In this embodiment, each step of the communication satellite sleep control method will be described by taking the integrated heaven-earth communication network shown in fig. 1 as an example.
In this embodiment, referring to fig. 2, a communication satellite sleep control method includes the following steps:
s1, detecting the coverage range of a communication satellite;
s2, determining at least one ground base station located in a coverage area;
s3, traffic prediction is carried out on each ground base station, and the duration time of the idle state of each ground base station is determined;
s4, controlling the communication satellite to sleep the target ground base station in a continuous time period; the target ground base station is a ground base station in an idle state for a duration.
In step S1, referring to fig. 3, the communication satellite reports its own state to the operation and control center at intervals of time, for example, 10 minutes, where the state includes the current position of the communication satellite, service information, a timestamp, a satellite ID, and the like, and the operation and control center returns response information to the communication satellite after receiving the information reported by the communication satellite. The operation and control center forwards the information reported by the communication satellite to the core network, and the core network calculates the ground coverage area of the communication signal sent by the current communication satellite according to the information reported by the communication satellite and the ephemeris data.
Referring to fig. 4, the ground base station returns response information to the ground base station at a time interval, for example, 10 minutes, to the core network's own state, including service information, a timestamp, a satellite ID, and the like of the ground base station, after receiving the information reported by the ground base station. Under the condition that the ground base station is a fixed base station, the position of the ground base station is unchanged, and the core network can store the position of the ground base station; in the case that the ground base station is a mobile base station, the position of the ground base station is changed, and the ground base station can report the position of the ground base station to the core network at regular time.
In step S2, the core network determines all available ground base stations located within the coverage area according to the coverage area reported by the communication satellite and the position of the ground base station. Specifically, the core network only needs to determine whether the position coordinates of the ground base station are included in the coverage area reported by the communication satellite. The number of the terrestrial base stations determined by the core network may be zero, one or more, and in this embodiment, only the case that the number of the terrestrial base stations determined is one or more is considered.
When the core network performs step S3, that is, performs traffic prediction on each of the ground base stations, and determines the duration period of the idle state of each of the ground base stations, the following steps may be specifically performed:
s301, acquiring historical traffic time sequences of all ground base stations;
s302, predicting to obtain a future traffic time sequence according to the historical traffic time sequence by using a time sequence prediction algorithm;
and S303, determining the time period in which the value lower than the traffic threshold value in the future traffic time sequence is positioned as the duration time period of the idle state.
In step S301, the core network may count the historical traffic volume of each of the ground base stations determined in step S2 in a period of time before. For example, for one of the terrestrial base stations having ID 1 determined through step S2, the historical traffic volume of the previous 6 minutes is acquired, thereby obtaining the traffic volume of the form shown in table 1 by x 1 -x 7 And a corresponding historical traffic time series of generation times.
TABLE 1
In step S302, a time series prediction algorithm such as sliding window average, Holt' S linear trend or Arima method is used to predict and obtain the x in Table 1 according to the historical traffic time series 8 -x 10 And a corresponding generation time. In this embodiment, the length of the future traffic time series may be 1, that is, the traffic at a time point in the future is predicted, for example, the traffic x of the ground base station 1 in 1 minute in the future is predicted 8 。
In step S303, a traffic threshold x may be set 0 Respectively, to obtain the predicted future traffic x 8 、x 9 、x 10 And traffic threshold x 0 In comparison, it is determined whether the ground base station 1 is in an idle state or a busy state. For example, if x 8 ＜x 0 Then it is determined that the terrestrial base station 1 is at x 8 Corresponding to an idle state at 1 st minute in the future, if x 8 ≥x 0 Then it is determined that the terrestrial base station 1 is at x 8 The corresponding future 1 st minute is busy.
In step S303, if it is determined that the ground base station 1 is at x 8 Corresponding future 1 minute, at x 9 Corresponding future 2 nd minute at x 10 Corresponding to the 3 rd minute being idle state, it may be determined that the terrestrial base station 1 is idle state for the 3 minutes in the future, that is, the duration of time for which the terrestrial base station 1 is determined to be idle state is the 3 minutes in the future calculated from the current time.
In step S303, if it is determined that the ground base station 1 is at x 8 Corresponding to busy state at the 1 st future minute, determined at x 9 Corresponding future 2 min at x 10 Corresponding to the 3 rd minute in the future is idle, then it can be confirmedIt is determined that the terrestrial base station 1 is busy in the 1 st minute in the future and is idle in both the 2 nd and 3 rd minutes in the future, that is, the duration of time for determining that the terrestrial base station 1 is idle is counted from the 2 nd minute in the future to the 3 rd minute in the future.
In step S303, if it is determined that x is 8 Corresponding future 1 st minute at x 9 Corresponding to the 2 nd minute in the future, the state is idle and is determined to be in x 10 Corresponding to busy state at the future 3 rd minute, it may be determined that ground base station 1 is in an idle state at both the 1 st and 2 nd minutes in the future and is in a busy state at the future 3 rd minute, that is, it is determined that the duration time period during which ground base station 1 is in an idle state is 2 minutes in the future counted from the current time.
The above steps S301 to S303 determine idle state duration periods of the ground base station with ID 1, that is, the ground base station 1, and may determine idle state duration periods of other ground base stations within the coverage area of the communication satellite based on the same procedure.
When there are multiple terrestrial base stations in the coverage area of a communication satellite, it may be predicted that some of the terrestrial base stations will be busy for some future time, and thus there will naturally be no corresponding idle duration for these terrestrial base stations. For the terrestrial base stations having the corresponding idle state duration periods, the idle state duration periods corresponding to the terrestrial base stations may coincide, or there may be a case where the idle state duration periods corresponding to all the terrestrial base stations partially coincide. Fig. 5 shows a case where a plurality of ground base stations such as ground base station 1, ground base station 2, ground base station 3, ground base station 4, and ground base station 5 exist in the coverage area of the communication satellite, and the idle state duration period of each ground base station is described.
Referring to fig. 5, for a certain determined time period, which belongs to an idle state duration time period for some terrestrial base stations and belongs to a busy state duration time period for other terrestrial base stations, in this embodiment, when referring to one determined idle state duration time period, the terrestrial base station in an idle state in this time period is referred to as a target terrestrial base station. For example, in fig. 5, during the time period t1-t2, the terrestrial base station 3 and the terrestrial base station 4 are in an idle state, and thus both the terrestrial base station 3 and the terrestrial base station 4 are target terrestrial base stations for the time period t1-t 2; during the time period t2-t3, only the terrestrial base station 3 is in an idle state, and therefore only the terrestrial base station 3 is the target terrestrial base station for the time period t2-t 3.
In step S4, the core network controls the communication satellite to sleep for the target ground base station for the duration of the idle state.
When step S4 is executed, the core network may specifically execute the following steps:
s401, determining a target user terminal;
s402, controlling the communication satellite to close the multiple access of the target user terminal in the continuous time period.
The target ue in step S401 is a ue accessing to the target ground bs. For example, for the time period t1-t2, since the terrestrial base station 3 and the terrestrial base station 4 are in the idle state in the time period t1-t2, the terrestrial base station 3 and the terrestrial base station 4 are both target terrestrial base stations, and the user terminals accessing the terrestrial base station 3 and the terrestrial base station 4 in the time period t1-t2 are both target user terminals. In step S402, the core network controls the communication satellite to stop the target ue, i.e. the ues accessing the terrestrial bs 3 and the terrestrial bs 4 within the time period t1-t2, from accessing the communication satellite within the time period t1-t 2.
Specifically, the communication satellite is accessed by different user terminals through multiple access techniques such as time division multiple access, code division multiple access, or frequency division multiple access, so that the communication satellite can identify different user terminals and can stop access of some user terminals without stopping access of other user terminals. Therefore, in step S402, during the time period t1-t2, the communication satellite may close access only to the user terminals accessing the terrestrial base stations 3 and 4, i.e., the target user terminals, which are rejected by the communication satellite or the core network if an access request is made to the communication satellite.
For the time period t2-t3, since only the terrestrial base station 3 is in the idle state for the time period t2-t3, only the terrestrial base station 3 is the target terrestrial base station, and all the user terminals accessing the terrestrial base station 3 for the time period t2-t3 are target user terminals. In step S402, the core network controls the communication satellite to stop the target ue, i.e. the ue accessing the terrestrial bs 3 in the time period t2-t3, from accessing the communication satellite in the time period t2-t 3.
In step S402, referring to the flow shown in fig. 6, the core network sends a sleep request to the operation and control center, the operation and control center forwards the sleep request to the communication satellite, the communication satellite switches the target ground base station and the target user terminal connected to the target ground base station to a sleep state, and returns response information to the operation and control center, and the operation and control center forwards the response information to the core network.
By executing steps S401 to S402, the communication satellite can be controlled to close the access of the target user terminal connected to the target ground base station within the idle state duration of the target ground base station, so that the communication satellite is dormant with respect to the target ground base station and the target user terminal connected thereto, thereby reducing the number of user terminals accessed to the communication satellite, and the communication satellite does not need to perform operations such as channel detection on the target user terminal, thereby reducing the load of the communication satellite; since the target ground base station is in the idle state during the idle state duration period and can provide the communication service for the target user terminal, the communication quality of the target user terminal can be guaranteed, and thus, the communication satellite sleep control method in this embodiment can balance the load of the communication satellite and the communication service quality provided by the communication satellite.
When the core network performs step S4, that is, the core network controls the communication satellite to sleep for the target ground base station for the duration of time, the following steps may also be performed:
and S403, controlling the communication satellite to open the multiple access of other user terminals except the target user terminal in the continuous time period.
In performing step S403, the communication satellite may not change the configuration of the user terminals other than the target user terminal, and the user terminals other than the target user terminal may be switched to connect with the communication satellite from the terrestrial base station to which the user terminals are connected.
By performing step S403, the communication satellite may be in a dormant state only with respect to the target terrestrial base station and the target ue connected thereto, and may be in an active state with respect to other terrestrial base stations except the target terrestrial base station and the ues connected thereto, and the other ues except the target ue may access the communication satellite to provide communication services through the communication satellite, thereby ensuring the quality of the communication services obtained by the other ues except the target ue.
When the core network performs step S4, that is, the step of controlling the communication satellite to sleep for the target ground base station for the duration of time, the core network may further perform the following steps:
and S404, controlling the communication satellite to restore and open the multiple access of all the user terminals after the duration period is ended.
The ending of the duration in step S404 may refer to ending of the idle state duration of all the ground base stations, that is, all the ground base stations are in a busy state, at this time, the communication satellite resumes opening the multiple access of all the user terminals, so that all the user terminals can be switched from the ground base station connected to the communication satellite to be connected to the communication satellite, or after applying for access to the ground base station is denied, the communication satellite is accessed to obtain communication service, thereby ensuring the quality of the communication service obtained by the user terminals.
When the core network performs step S4, that is, the step of controlling the communication satellite to sleep for the target ground base station for the duration of time, the core network may further perform the following steps:
s405, when all the ground base stations in the coverage range are target ground base stations, controlling the communication satellite to intermittently open the multiple access of the user terminals in the continuous time period, and closing the multiple access of all the user terminals in other time periods in the continuous time period.
In step S405, when all the ground base stations in the coverage area are target ground base stations, it indicates that all the ground base stations in the coverage area are in an idle state within a certain period of time, because the communication service quality provided by the ground base stations to the user terminal is better than that of the communication satellite under the same condition, and the ground base stations are in the idle state, it indicates that the ground base stations are available to the user terminal, the user terminal can be connected to the ground base stations, and the service demand for the communication satellite is low, therefore, the core network can control the communication satellite to set all the ground base stations and the user terminals connected thereto in a sleep state, that is, to turn off the multiple access of all the user terminals, thereby reducing the resource consumption of the communication satellite. In the idle state continuous time period, the communication satellite intermittently opens the multiple access of the user terminal, if the user terminal cannot be connected to the ground base station due to a burst reason, paging can be continuously sent out, and when the communication satellite opens the multiple access, the communication satellite can receive the access request of the user terminal, so that the communication service is provided for the user terminal, and the emergency requirement is met.
In this embodiment, before executing step S4, that is, before controlling the communication satellite to sleep for the target ground base station within the duration, a time threshold t0 may be set, and the relationship between the length of the duration of the idle state and the time threshold t0 may be determined. If the duration of the idle state is less than t0, then the steps S401-S405 may not be executed, and multiple access of all the user terminals may be opened, which is equivalent to the communication satellite not entering the sleep state, and providing normal communication service for all the user terminals.
For example, in the flow shown in fig. 5, if the length of the time period t1-t2 is less than the time threshold t0, even if the terrestrial base station 3 and the terrestrial base station 4 are both in the idle state during this time period, the communication satellite may not enter the sleep state for the terrestrial base station 3 and the terrestrial base station 4 and the connected user terminals, and open the access of all the user terminals as usual. Whether the communication satellite enters the dormant state is determined by judging the relation between the length of the duration time period of the idle state and the time threshold, so that the working state of the communication satellite is prevented from being frequently changed when the duration time period of the idle state is too short, and the stability of a communication network is favorably maintained.
In this embodiment, the core network may further perform the following steps:
s5, receiving a wake-up request sent by a target user terminal;
s6, forwarding the awakening request to a communication satellite, a core network or an operation control center;
and S7, responding to the awakening request, and controlling the communication satellite to recover the multiple access of the open target user terminal.
In step S5, the core network may receive the wake-up request sent by the target ue through the target ground bs, and in step S6, the core network may directly respond to the wake-up request, or forward the wake-up request to the communication satellite or the operation and control center, and in step S7, the communication satellite is controlled to leave the dormant state, so as to resume opening the multiple access of the target ue. By performing steps S5-S7, the communication satellite may be awakened such that the communication satellite opens access for the target user terminal even during the idle state duration of the target terrestrial base station, thereby satisfying emergency communication requirements.
The core network can set the limits of the authority and times of the user terminal for sending the wake-up request, namely only a specific user terminal can send the wake-up request, and the number of times of sending the wake-up request by each user terminal in a period of time is limited, so that the working state of the communication satellite is prevented from being frequently changed due to the fact that the communication satellite frequently responds to the wake-up request in a short time, and the stability of a communication network is maintained. The core network can set the authority and the frequency limit of the wake-up request sent by the user terminal through the commercial service system, and the authority and the frequency limit of the wake-up request are granted to the user terminal after the commercial conditions such as payment are met.
In this embodiment, a heaven-earth integrated communication network may be established through a communication satellite and a ground base station core network, where the core network may be configured to execute any step and combination of steps S1-S5 in this embodiment, so as to achieve the same technical effect as the communication satellite sleep control method in this embodiment.
The communication satellite sleep control method in the present embodiment may be implemented by writing a computer program for implementing the communication satellite sleep control method in the present embodiment, writing the computer program into a computer device or a storage medium, and executing the communication satellite sleep control method in the present embodiment when the computer program is read out and run, thereby achieving the same technical effects as the communication satellite sleep control method in the present embodiment.
