Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an information processing method and apparatus, and a readable storage medium.
Background
In recent years, giant constellations characterized by low orbits have rapidly evolved. Generally, satellite communications loads tend to use beam-hopping modes of operation subject to a number of factors such as power.
Giant constellations typically use a phased construction approach. As shown in fig. 1 and fig. 2, schematic diagrams of coverage elevation angles and terminal scanning angles of satellites before and after constellation expansion are shown. In the initial construction stage of the constellation (referred to as an original constellation for short), because of the continuous coverage formed by the small number of satellites, the capabilities of the corresponding satellites and the terminal need to be stronger, for example, the satellites have an elevation angle (-B1-0 DEG, 0-B1) with a larger coverage range, and the terminal has a scanning angle (-A1-90 DEG, 90-A1) with a larger scanning range; in the later construction stage of the constellation (referred to as "expanded constellation"), because of the continuous coverage formed by a greater number of satellites, the capabilities of the corresponding satellites and the terminals can be weakened, i.e., the elevation angles (-B2-0 °, 0 ° -B2) covered by the satellites can be reduced (i.e., B2< B1), and the scanning ranges (-a 2- — 90 °, 90 ° -a 2) of the terminals can also be reduced (i.e., a2> a 1). The cost of the satellite decreases as the elevation angle covered by the satellite decreases, and the cost of the terminal decreases as the range scanned by the terminal decreases. Therefore, the expansion of the constellation can reduce the terminal cost, thereby promoting the maturity of the industry.
As shown in fig. 3(a) and 3(b), after the constellation system is expanded, the coverage area of each satellite in the original constellation system needs to be reduced to reduce interference caused by overlapping coverage of adjacent satellites. For a satellite communication system using beam hopping, the coverage of the satellite is reduced, which means that the wave position of the beam hopping needs to be changed, i.e. the wave position of the original coverage is adjusted to the wave position of the new coverage. The change in the number of bits affects both the network and the terminal, and therefore, it is necessary to take appropriate measures to solve the problem to ensure normal communication.

Referring to fig. 4, fig. 4 is a flowchart of an information processing method provided in an embodiment of the present application, and as shown in fig. 4, the method includes the following steps:
the satellite communication system supports the total wave position number of the wave beams, the number of the wave beams, frequency point information of each wave beam, the wave position number corresponding to each wave beam, the residence time of the wave beam at each wave position and the scanning pattern of the wave beam at the wave position.
Where wave location refers to the footprint of the beam on the earth's surface in a particular orientation. The beam may be a control beam or a traffic beam.
For example, for a control beam, in practical application, for a low-earth-orbit satellite communication system using a hopping beam, after a co-frequency capacity expansion of a same-layer orbit is performed on a constellation system, in order to ensure normal communication, a network device may send information of the control beam to a terminal, where the information of the control beam includes:
the satellite communication system supports the total wave position number of control beams, the number of the control beams, frequency point information of each control beam, the wave position number corresponding to each control beam, the residence time of each control beam in each wave position and the scanning pattern of each control beam in the wave position.
Wherein the maximum value (L) of the wave position number corresponding to the control wave beam max ) The maximum value of the wave bit number which can be supported by all low-orbit satellites before and after capacity expansion needs to be reflected, the total wave bit number of the control wave beams supported by the satellite communication system, namely the actual wave bit number (L) corresponding to the control wave beams can be flexibly adjusted, and the condition that L is more than or equal to 1 and less than or equal to L is met max 。
In particular, if there is only one control beam, the network device may send to the terminal the number of bits corresponding to the control beam, the dwell time of the beam at each bit, and the scan pattern of the beam at the bit.
The number of wave positions supported by a single control beam can be different before and after capacity expansion, and the number of wave positions supported by a plurality of control beams can be the same or different.
In practical applications, the network device may send the information of the beam to the terminal in a broadcast manner, or may also agree with the terminal for the information of the beam.
As shown in fig. 5, it is assumed that the satellite system supports a coverage of 112 wave bits at the initial construction. After subsequent capacity expansion, because the actual coverage area of each satellite is reduced, the satellite in the original system can only support the coverage area of 72 wave bits without supporting 112 wave bits. Therefore, the satellite system needs to determine two parameters related to the number of wave bits corresponding to the control beam, one of which is the maximum value (L) of the number of wave bits corresponding to the control beam max 112), which is the number of bits corresponding to the supported control beam (L72), and L may be broadcast to the terminal through a system message.
In the embodiment of the present application, the scan pattern of the beams at the wave positions may include or may not include the geographical adjacent relationship of the beams between different wave positions. If not, the network device may further send indication information to the terminal, where the indication information is used to indicate information of a neighboring wave position of the wave position corresponding to the beam where the terminal is currently located. The geographical adjacent relation between different wave positions refers to the geographical position relation between adjacent wave positions. For example, the geographic adjacency may be formed by the information of a wave position a and its adjacent wave positions in the south, southeast, east, northeast, northwest, west, and southwest directions.
For the case of a single steering beam, a wave bit scan pattern of the steering beam is shown, as shown in FIG. 6. Assuming that the dwell time of the control beam at each wave bit is 3ms, the control beam completes one scan of all wave bits, and it takes 3ms × 112 to 336ms for 112 wave bits in the original constellation system, and it takes 3ms × 72 to 216ms for 72 wave bits in the expanded constellation.
For the case of multiple control beams, a wave bit scan pattern of two control beams is shown, as shown in FIG. 7. Assuming that the dwell time of the control beam at each wave bit is 3ms, the control beam completes one scan of all wave bits, and it takes 3ms (112/2) × (168 ms) for 112 wave bits in the original constellation system, and it takes 3ms (72/2) × (108 ms) for 72 wave bits in the expanded constellation system.
In practical application, the scan pattern of the wave position of the wave beam comprises the index number of the wave position of the wave beam and the service time of the wave position of the wave beam; alternatively, the scan pattern of the beam at the wave position comprises an index number of the beam at the wave position, a service time of the beam at the wave position, and a geographical adjacent relationship of the beam between different wave positions.
In the embodiment of the present application, the scanning pattern of the beam at the wave position can be embodied by a wave position scanning list. As shown in table 1, a mapping relationship between the index number of wave bits and the service time (alternatively referred to as scanning time) of the wave beam in the wave bits is shown.
TABLE 1
Of course, the wave position scanning list may also be recorded in a two-dimensional manner, as shown in table 2, the scanning pattern may reflect both the mapping relationship between the wave position index number and the service time of the beam in the wave position, and the geographic neighboring relationship between the wave positions. Therefore, for any wave position, the adjacent wave positions corresponding to different azimuths can be clearly known.
TABLE 2
Through the obtained scan pattern, the terminal can determine a search detection window of the wave position signal based on the wave position scan table, and can start RRM (Radio resource management) measurement of the adjacent wave position based on the currently-residing wave position number. In this way, the bit number occupied by the pattern is controllable, so that the resource can be saved.
In the embodiment of the application, the network device of the satellite communication system sends the information of the beam to the terminal, so that the terminal can determine the time sequence relation of the downlink signal according to the wave position information corresponding to the currently-resident beam and the information of the beam, thereby ensuring normal communication.
Referring to fig. 8, fig. 8 is a flowchart of an information processing method provided in an embodiment of the present application, and as shown in fig. 4, the method includes the following steps:
After the terminal is started, one beam is searched and resided in first, and the wave bit index number corresponding to the beam is obtained. Because the number of satellites in the original satellite system is small, the satellites correspond to a larger coverage area, which also means that the terminal needs to support a larger search angle. After the expansion, the satellite corresponds to a smaller coverage, which also means that the terminal only needs to support a smaller search angle. For the existing terminal, if the satellite searching is always performed according to the supported larger searching angle range every time, on one hand, the satellite searching time is too long, and on the other hand, the satellite with the best quality may not be accessed. In order to solve the problem, the terminal can adopt a priority search mode in star searching to reduce the search complexity.
Specifically, the terminal may search according to the historical search angle, select the currently-resident beam according to the search result, and determine the wave position information corresponding to the currently-resident beam. Wherein, the historical search angle may be the search angle adopted by the last search, and the like. Or, the terminal may also search according to the historical beam coverage information, select the currently-residing beam according to the search result, and determine the wave position information corresponding to the currently-residing beam. For example, the network may notify the terminal of the maximum number of waves or the maximum coverage angle, and then the terminal derives the search angle of the terminal based on the information notified by the network, and preferentially searches within the range of the search angle.
For example, assume that the minimum search elevation angle of a terminal under the original satellite system is 10 °; after capacity expansion, the minimum search elevation angle of the terminal is 30 degrees. If the terminal of the original satellite system searches for satellites according to the capability range of the terminal [ 10-90 degrees, -90 degrees to-10 degrees ], the search of the terminal in the range of [ 10-30 degrees, -30 degrees to-10 degrees ] is a waste of time. Therefore, the terminal records the angle of successful satellite search each time, and after a period of training, the terminal can automatically judge that the minimum elevation angle of successful satellite search of the terminal is 30 degrees, and then during subsequent satellite search, the terminal only needs to search for satellites within the range of (30 degrees to 90 degrees, -90 degrees to-30 degrees). Or the network informs the terminal of the maximum coverage angle of the satellite under the expanded constellation, so that the terminal calculates the minimum elevation angle of the satellite under the maximum coverage angle of the satellite to be 30 degrees, and only needs to search for the satellite within the range of (30-90 degrees, -90-30 degrees) during subsequent satellite searching.
The information of the beam may be preset or may be sent by the network device. Thus, in a sub-step, the terminal may receive information of said beam transmitted by the network device of the satellite system; or, acquiring information of a preset beam. Wherein the information of the beam comprises: the total wave position number of wave beams supported by the satellite communication system, the number of the wave beams, frequency point information of each wave beam, the wave position number corresponding to each wave beam, the residence time of the wave beam at each wave position and the scanning pattern of the wave beam at the wave position.
Optionally, in the information of the beam, the scan pattern of the beam at the wave position may include a geographical adjacent relationship of the beam between different wave positions. At this time, the terminal may determine the timing relationship of the downlink signal according to the information of the adjacent wave bits.
The network device may send this information to the terminal if the scan pattern of beams at wave positions does not include the geographical proximity of beams between different wave positions. Correspondingly, the terminal may receive indication information sent by a network device of the satellite system, where the indication information is used to indicate information of an adjacent wave position of a wave position corresponding to a beam where the terminal is currently located. At this time, the terminal determines the time sequence relationship of the downlink signal according to the wave position information corresponding to the currently-resident wave beam and the information of the adjacent wave position of the wave position corresponding to the wave beam where the terminal is currently located.
Specifically, in the process of determining the time sequence relationship of the downlink signal, the terminal obtains information of adjacent wave bits based on the index number of the wave bit where the terminal is located and the geographical adjacent relationship of the wave beam between different wave bits, and determines the time sequence relationship of the downlink signal according to the information such as the residence time of the wave beam at each wave bit, thereby ensuring the control processes such as data transmission and switching.
As shown in fig. 9, assuming that the terminal currently resides in the #1 wave position, the network device may notify the terminal of information of adjacent wave positions (for example, wave positions #2 to #9 of the adjacent wave position # 1) of the wave position where the terminal resides, so that the terminal can perform measurement specifically, which is beneficial to handover. Namely, aiming at the switching caused by the satellite movement, the terminal can measure in advance based on the known adjacent wave position information, thereby not only avoiding the complexity of blind measurement, but also shortening the measurement time; the terminal can rapidly perform the wave position synchronization and measurement operation based on the wave position and the known wave position scanning information.
In the embodiment of the application, the network device of the satellite communication system sends the information of the beam to the terminal, so that the terminal can determine the time sequence relation of the downlink signal according to the wave position information corresponding to the currently-resident beam and the information of the beam, thereby ensuring normal communication. For a low-orbit satellite communication system using beam hopping, software and hardware upgrading is not needed in the scheme of the embodiment of the application, so that the implementation is simple.
It should be noted that the method of the present invention is also applicable to a terrestrial communication system using beam hopping.
As shown in fig. 10, an information processing apparatus according to an embodiment of the present application is applied to a network device of a satellite communication system, and includes: the processor 1000, which is used to read the program in the memory 1020, executes the following processes:
