[0035] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] For mobile base stations, especially mobile base stations with large coverage areas, such as satellite base stations, the present disclosure proposes an information processing method. Figures 1 to 3 Give a description.

[0037] Figure 1 Flowcharts of some embodiments of the information processing method disclosed in the present invention. Figure 1 As shown, the method of this embodiment includes: steps S102 to S104.

[0038] In step S102, the core network element obtains information about the current coverage area corresponding to the base station.

[0039] In some embodiments, the base station sends information about the current coverage area to the core network element, and correspondingly, the core network element receives the information about the current coverage area sent by the base station.

[0040] The coverage area is not necessarily the area covered by the signal of the base station, but a fixed area pre-divided on the ground, which can also be called a tracking area group, etc., and is named according to actual needs and is not limited to the examples given. In some embodiments, the ground is divided into different coverage areas, and each coverage area corresponds to a group (multiple) of tracking areas. Each coverage area can be configured with a unique identifier (for example, a code). For example, the information of the current coverage area includes the identifier of the current coverage area. Figure 2 As shown, the areas of the four TAs TA1, TA2, TA3, and TA4 are coded as coverage area a, and the areas of the four TAs TA5, TA6, TA7, and TA8 are coded as coverage area b.

[0041] In some embodiments, the ground tracking areas covered by the base station can be grouped and the corresponding identifiers can be determined according to the movement law of the base station. For example, the base station can be set on a satellite that moves relative to the ground (such as a medium- and low-orbit satellite). For example, according to the orbital characteristics and laws of the satellite (base station), the ground TAs covered by the satellite (base station) are grouped and encoded. For example, when the satellite (base station) moves to a position, the group of TAs covered corresponds to the encoding of a coverage area, and when the satellite (base station) moves to the next position, the group of TAs covered corresponds to the encoding of the next coverage area.

[0042] The number of tracking areas corresponding to each coverage area can be the same or different, and the number of tracking areas corresponding to each coverage area can be greater than or equal to the number of tracking areas actually physically covered by the base station. For example, the number of TAs contained in each coverage area can be greater than the number of TAs that the satellite (base station) can actually physically cover, that is, the area of ​​the coverage area is larger than the area covered by the satellite signal. This processing is applicable to the case where the satellite (base station) uses a dynamic scanning beam instead of a staring beam.

[0043] The tracking areas corresponding to different coverage areas may be completely different. Alternatively, the tracking areas corresponding to different coverage areas may be at least partially different. For example, the multiple TAs corresponding to coverage areas a and b may be partially overlapped / identical.

[0044] In some embodiments, when the base station moves to a range corresponding to the current coverage area, information about the current coverage area is sent to the core network element. Different coverage areas may correspond to different location points, and when the base station moves to the corresponding location point, information about the current coverage area is sent to the core network element.

[0045] For example, when the base station is moving, such as when the base station is located on a moving satellite, the base station sends the information (code) of the current coverage area to the core network element. When the base station moves to the next location and the coverage area changes, the base station sends the information (code) of the new coverage area to the core network element. Figure 2As shown, when the signal of the satellite (base station) covers the coverage area a, it sends its current coverage area a to the core network element; when the satellite (base station) moves, when the signal covers the coverage area b, it sends its current coverage area b to the core network element.

[0046] In some embodiments, the base station sends connection establishment information or radio access network configuration update information to the core network element, and correspondingly, the core network element receives the connection establishment information or radio access network configuration update information sent by the base station, wherein the connection establishment information or radio access network configuration update information includes information about the current coverage area. The base station can send the information about the current coverage area to the core network element during the connection establishment or RAN (Radio Access Network) configuration update process.

[0047] For example, when the satellite (base station) is turned on, or when the satellite (base station) needs to connect to a new core network due to large-scale movement, it initiates connection establishment to the core network element. When the current coverage area of ​​the satellite (base station) changes, it initiates RAN configuration update information to the core network element.

[0048] In some embodiments, in 5G (5th Generation Mobile Communication Technology), the core network element is AMF (Access and Mobility Management Function).

[0049] In some embodiments, the core network element queries the information of the current coverage area corresponding to the base station according to the information of the base station. The relevant embodiments will be described in detail later.

[0050] In step S104, the core network element determines the current tracking area corresponding to the base station according to the information of the current coverage area.

[0051] In some embodiments, the core network element determines the tracking area corresponding to the information of the current coverage area according to the correspondence between the information of each coverage area and the tracking area stored, as the current tracking area corresponding to the base station; and / or the core network element queries other network elements for the tracking area corresponding to the information of the current coverage area, as the current tracking area corresponding to the base station. The other network elements may be other network elements in the core network except the core network element.

[0052] For example, the core network element can query the obtained base station coverage area information based on the information of different coverage areas and the corresponding TA information table within itself, and query the specific TA corresponding to the base station. If the core network element does not store the coverage area information and the corresponding TA, it can query other network elements. Other network elements query based on the information of different coverage areas and the corresponding TA information table within themselves, and return to the core network element when multiple TAs corresponding to the current coverage area information are queried. For example, Figure 2 As shown, the current coverage area is a, then the TAs corresponding to the core network element query are TA1, TA2, TA3, and TA4. After the base station moves, the current coverage area is b, then the TAs corresponding to the core network element query are TA5, TA6, TA7, and TA8.

[0053] In some embodiments, the core network element determines a current tracking area corresponding to the base station from a group of tracking areas corresponding to the current coverage area according to the movement law of the base station. For example, for a satellite (base station), the position of the satellite at any time can be determined according to ephemeris information, thereby determining a current tracking area corresponding to the base station from a group of tracking areas corresponding to the current coverage area. It is more accurate to determine the current tracking area corresponding to the base station through the base station report and the core network element based on the movement law of the base station.

[0054] In some embodiments, the core network element performs mobility management according to the current tracking area corresponding to each base station.

[0055] In some embodiments, the core network element matches the tracking area to which the terminal belongs with the current tracking area corresponding to each base station to determine the target base station; and sends a paging indication to the target base station so that the target base station pages the terminal. For example, when there is a downlink service, the core network element initiates paging to one or more satellites (base stations) currently covering the TA according to the location of the terminal (indicated by a specific TA).

[0056] In the method of the above embodiment, the ground is divided into different coverage areas, each coverage area corresponds to a group of tracking areas, and the base station only needs to send the information of the current coverage area to the core network element after the corresponding coverage area changes. The core network element determines the current tracking area corresponding to the base station based on the information of the current coverage area. Since the coverage area corresponds to a group of tracking areas, that is, the area of ​​the coverage area is larger, the signaling of the wireless network information update between the core network element and the base station caused by the movement of the base station is reduced, saving signaling resources. The solution of the above embodiment is suitable for the scenario where the base station is set on a moving satellite, which improves the actual networking capability of a large-scale satellite constellation based on 3GPP mobile communication technology.

[0057] For base stations with regular movements, such as base stations installed on mobile satellites, the satellite's orbit is actually controlled and predictable. The signaling interaction between core network elements and base stations can be further reduced based on the movement patterns.

[0058] Combine the following Figure 3 Other embodiments of the information processing method disclosed herein are described.

[0059] Figure 3 Flowcharts of other embodiments of the information processing method disclosed in the present invention. Figure 3 As shown, the method of this embodiment includes: steps S302 to S304.

[0060] In step S302, the core network element queries the information of the current coverage area corresponding to the base station according to the information of the base station.

[0061] In some embodiments, when the information of the current coverage area sent by the base station is not received, the information of the current coverage area corresponding to the base station is queried according to the information of the base station, which can be used in parallel with step 102 as a processing method of the core network element in different situations.

[0062] The core network element actively queries the information of the current coverage area corresponding to the base station, which can be triggered periodically or after a long period (preset time) without receiving the information of the current coverage area sent by the base station, and is not limited to the examples given. For base stations that can determine the position at different times according to the law of movement, the signaling interaction process between the core network element and the base station can be completely omitted, and the core network element only queries the information of the current coverage area corresponding to the base station according to the information of the base station.

[0063] For example, if the IP of the satellite (base station) remains unchanged and the connection with the core network remains unchanged, the core network can obtain information about the coverage area corresponding to the satellite at different times based on the query.

[0064] In some embodiments, the core network network element queries the stored information of the coverage area corresponding to the base station at each time based on the information of the base station, and determines the information of the current coverage area corresponding to the base station at the current time; and / or queries other network elements for the information of the current coverage area corresponding to the base station based on the information of the base station.

[0065] For example, the core network element can store the correspondence between the information (identification) of each base station and the motion information (e.g., ephemeris information, etc.) of the base station to determine the information of the coverage area corresponding to the base station at different times. The core network element can also access other network elements to determine the information of the current coverage area corresponding to the base station.

[0066] In step S304, the core network element determines the current tracking area corresponding to the base station according to the information of the current coverage area.

[0067] In some embodiments, the core network element determines the tracking area corresponding to the information of the current coverage area according to the correspondence between the information of each coverage area and the tracking area stored, as the current tracking area corresponding to the base station; and / or queries other network elements for the tracking area corresponding to the information of the current coverage area, as the current tracking area corresponding to the base station. For details, please refer to the above embodiments, which will not be repeated here.

[0068] The core network element can query other network elements to obtain information about the coverage area covered by a certain base station at different times and the corresponding specific TA. After the core network element determines the current tracking area corresponding to the base station, it performs mobility management operations.

[0069] The method of the above embodiment can further reduce the signaling of wireless network information update between the core network element and the base station due to the movement of the base station, thereby saving signaling resources.

[0076] The determination module 420 is used to determine the current tracking area corresponding to the base station according to the information of the current coverage area.
