Detailed Description
For the purposes of brevity and explanation, the principles of the present application are described herein with reference primarily to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of power consumption control methods for mobile terminals, and storage media, and that these same or similar principles may be implemented therein, with any such variations not departing from the true spirit and scope of the present application.
regional/Global Positioning (augmentation) systems such as beidou, GPS (Global Positioning System), glonass, galileo, QZSS (Quasi-Zenith Satellite System) and the like are mature and are currently popularized in terminal devices such as mobile phones. However, because the constellation orbit height of such a system is high, the communication delay is large, the path loss is high, and the transmission rate is low. On the other hand, by combining the low-orbit satellite constellation almanac (ephemeris) and the positioning of the terminal device by the above positioning system, the low-orbit satellite over-top time and the time interval therebetween of the current position of the device can be calculated. Such information may be used to reduce the overhead of the terminal device.
A common satellite communication system includes User Equipment (UE) and network equipment. The user equipment may also be referred to as terminal equipment, user terminals, mobile stations, etc. The network devices may include one or more satellite or ground station devices, which may also be referred to as core network devices. The satellites may be Low Earth Orbit (LEO) satellites (otherwise known as low earth orbit satellites), non-geostationary orbit (NGEO) satellites, and the like.
A mobile terminal (terminal device) in this context includes various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and may particularly refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or a user equipment having wireless communication capabilities. The terminal device may also be a satellite phone, a cellular phone, a smart phone, a wireless data card, a wireless modem, a machine type communication device, which may be a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device or wearable device, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote medical (remote medical) network, a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (security), a wireless terminal in urban wireless network (G), or a future wireless network in a wireless network (G5). The mobile terminal may be powered by a battery, may be attached to and powered by a power supply system of a vehicle or a vessel. The power supply system of the vehicle or the ship may also charge a battery of the mobile terminal to extend the communication time of the mobile terminal.
The ground station device is, for example, a device in a Core Network (CN) of an existing mobile communication architecture (e.g., a 3GPP access architecture of a 5G network) or a device in a core network of a future mobile communication architecture.
As shown in fig. 1, a constellation 10 of communication satellites (hereinafter referred to as constellation 10) is used to cover a portion of the earth. Wherein a number of low earth orbit satellites are included in the constellation 10. Two low earth satellites 101 and 102 and their coverage on the ground are schematically shown. It will be appreciated that the low earth satellites 101 and 102 will move around the earth at a faster rate, and thus the coverage of the satellites on the ground will also change in real time. When satellites 101 and 102 move to the illustrated positions, the position shown at point a in the figure is within the signal coverage of satellite 101, and thus mobile devices near point a may connect to satellite 101 to implement communication functions. Similarly, the location shown at point B is within the signal coverage of satellite 102, and mobile devices in the vicinity of point B may connect to satellite 102 to perform communication functions. And C is not within the signal coverage of any one satellite, a mobile terminal near point C is temporarily unable to establish contact with any one satellite in the constellation 10. At this time, power consumption of a satellite communication circuit (hereinafter, referred to as a communication circuit) of a mobile terminal near point C is substantially meaningless, and the following embodiments of the present application will describe how to reduce power consumption in this part of the scenario.
It should be noted that the principles of the present application are applicable not only to a communication satellite constellation including multiple satellites, but also to emergency communication scenarios where communication is provided only by a single satellite, and the like. Furthermore, the present application is not limited to each satellite in a constellation of communication satellites having to meet a particular frequency requirement. For example, each satellite in the constellation of communication satellites may have a different operating frequency band in the Ka/Q/V band.
According to an aspect of the present application, there is provided a power consumption control method for a mobile terminal. As shown in fig. 2, a power consumption control method 20 (hereinafter, referred to as method 20) for a mobile terminal includes the steps of: determining whether a communication satellite for connecting the mobile terminal exists at the position of the mobile terminal in step S202; and determining to switch the communication circuit of the mobile terminal to an operating state or a low power consumption state according to whether there is a communication satellite available for connection in step S204. The method 20 through the above steps can determine whether the mobile terminal is under the coverage of any satellite in the low earth orbit communication satellite constellation, so as to determine whether to turn on the corresponding satellite communication circuit, which will help to reduce the ineffective overhead of the mobile terminal.
The method 20 determines in step S202 whether a communication satellite to which the mobile terminal is connectable exists at the location where the mobile terminal is located. Since the communication satellite constellation is set to the target coverage at the beginning of its construction, in other words, there are always some areas (e.g., north and south regions of the earth) that are out of the coverage of the constellation due to cost, etc., and it is meaningless to turn on the communication circuit in these areas. For example, when a user flights through these areas with a mobile terminal on an intercontinental flight, the mobile terminal will have no communications satellites available for a period of time. These areas may be selected by a coordinate point box and recorded in the mobile terminal, and once they are entered, it may be determined that there are no communication satellites available to the mobile terminal, and that there may be communication satellites available outside of these areas.
The method 20 determines in step S204 to switch the communication circuit of the mobile terminal to an operating state or a low power consumption state according to whether there is a communication satellite available for connection, wherein the communication circuit is used for processing communication data generated when the mobile terminal communicates with the communication satellite. Continuing with the above example, if a user enters an area with a mobile terminal without available communication satellites, the communication circuitry of the mobile terminal may be switched to a low power state and remain in the low power state until moving out of the area.
The above example evaluates whether there are communication satellites available in the area in a rough manner, and the following example will calculate whether there are communication satellites available in the area in a more accurate manner.
In some embodiments of the present application, in step S202, it may be determined whether there is a communication satellite to which the mobile terminal is connectable at the position where the mobile terminal is located, based on the position information of the mobile terminal and the ephemeris information of the communication satellite. Specifically, in step S202, the position of the mobile terminal may be determined according to the positioning data of the mobile terminal, and ephemeris information of the communication satellite may be acquired. The position and ephemeris information may then be collated to determine whether a communication satellite is available for connection by the mobile terminal.
In some embodiments, the mobile terminal obtains the positioning data according to a satellite positioning system (the mobile terminal is configured with a satellite positioning function), a base station assisted positioning system (the mobile terminal is configured with a base station assisted positioning function), a wireless local area network assisted positioning system (the mobile terminal is configured with a wireless communication function), and the like. Specifically, the mobile terminal may acquire the current location information in real time or at certain time intervals. Of course, for a handheld, vehicle-mounted, or ship-mounted mobile terminal, the moving speed is low relative to the satellite speed, so that when evaluating whether there is a communication satellite to which the mobile terminal can connect, the mobile terminal can update its location information at a low frequency based on the location information acquired in the last positioning period.
In some embodiments of the present application, in step S202, it may be determined whether there is a communication satellite to which the mobile terminal is connectable according to an elevation angle of the satellite relative to the mobile terminal. Specifically, in step S202, in the case where it is determined that a communication satellite having an elevation angle higher than a predetermined angle with respect to the mobile terminal exists based on the position and ephemeris information, it is determined that a communication satellite to which the mobile terminal is connectable exists; and if there is no communication satellite having an elevation angle higher than the predetermined angle, it may be determined that there is no communication satellite to which the mobile terminal is connectable. In some examples, the predetermined angle may be set to 10 °. In other examples the predetermined angle may also be adjusted according to the sensitivity of the receiving device (mobile terminal) or the like.
In some embodiments, the mobile terminal may obtain the ephemeris information from a server, a communication satellite, that stores the ephemeris information. Specifically, the mobile terminal may obtain the updated ephemeris from a server at the ground station, while having an internet connection and being connectable to the ground station. In the case where the ground station cannot be connected, the mobile terminal may update ephemeris by communicating with the low-orbit satellite when establishing a communication connection with the low-orbit satellite.
In some embodiments of the present application, the communication circuit of the mobile terminal may be switched to an operating state by setting a timer in step S204. Specifically, in the case where the communication circuit is in the low power consumption state, it is possible to determine the latest time at which there is a communication satellite to which the mobile terminal is connectable based on the position and ephemeris information, and set a timer based on the latest time (referred to as a first timer for distinction). The communication circuit may be switched to an operational state after the first timer expires.
In some embodiments of the present application, the switching of the communication circuit of the mobile terminal to the low power consumption state in step S204 may be performed by setting a timer. Specifically, in the case where the communication circuit is in the operating state, it is possible to determine the latest time at which there is no communication satellite to which the mobile terminal is connectable based on the position and the ephemeris information, and set a timer (referred to as a second timer for distinction) based on the latest time. The communication circuit may be switched to a low power consumption state after the second timer expires.
The above processes of switching from the low power consumption state to the operating state and switching from the operating state to the low power consumption state may be repeated. In this way, the mobile terminal can be woken up when necessary, while the power consumption of the communication circuit is reduced or even switched off when there is no possibility of connection.
As a specific application scenario, according to the above-described embodiments, the mobile terminal may determine whether a communicable low-orbit satellite passes through the current position at the current time by combining the positioning information and the ephemeris, and the mobile terminal may determine whether a satellite at the nearest position is at a communicable position according to the ephemeris. For example, if the elevation angle to the current position is 10 ° or less, the communication is determined to be in the non-communicable state, and if the elevation angle to the current position is 10 ° or more, the communication is determined to be in the communicable state.
In some embodiments of the present application, the communication circuit includes a chip for processing communication data and peripheral circuits thereof. Further, switching the communication circuit to the low power consumption state also includes turning off the power supply of the communication circuit. If the mobile terminal judges that the current position of the current time has no communicable low-orbit satellite passing through the position of the equipment, the mobile terminal can control the satellite power supply management circuit to close the power supply of the satellite communication chip and peripheral circuits thereof or make the satellite communication chip and the peripheral circuits enter a low-power consumption state, and stop receiving and sending of the satellite transceiver chip so as to achieve the purpose of saving power consumption. Meanwhile, the mobile terminal can calculate the time interval of the low-orbit satellite predicted by the current position, set a timer and start the satellite communication circuit to enter a working state at regular time. For example, the mobile terminal calculates that the current nearest satellite is at an elevation angle of 5 degrees and is not available for communication, closes the satellite communication circuit, and calculates that the current area has satellites reaching the elevation angle of 10 degrees after 10 minutes, and then can set a timer to start the satellite communication circuit. During the period, the moving distance of the position of the equipment is limited, and the equipment can still be regarded as the same area, and after 10 minutes, the CPU of the mobile terminal can control the satellite power supply management chip to supply power to the satellite communication circuit or awaken the satellite communication circuit from a low power consumption state so as to enable the satellite communication circuit to enter a working state.
On the other hand, if the CPU judges that the current position of the current time is the position of the low-orbit satellite capable of communicating in the equipment, the satellite communication can be carried out, the expected time point of the low-orbit satellite is calculated, the time interval is calculated, the timer is set, and the power supply of the satellite communication chip and the peripheral circuits thereof can be turned off or the satellite communication chip and the peripheral circuits thereof can be put into a low-power consumption state after the timer is full.
