Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to methods for primary and secondary cell processing, terminals, and computer-storable media. Background Technology

[0002] Terrestrial mobile communication networks are constrained by factors such as network deployment costs and geographical environment, and cannot provide seamless global coverage. Satellite communication networks, on the other hand, have a wide coverage area, are less affected by geographical environment, and can serve as a supplement to terrestrial cellular networks, providing seamless global coverage.

[0003] In related technologies, terminals can only add or switch primary and secondary cells in terrestrial cellular networks based on cell signal quality conditions. Summary of the Invention

[0004] In non-terrestrial access network scenarios, the signal quality difference between the cell center and cell edge is not significant. At the same time, the relative positions of terminals and satellites are complex and changeable. Relying solely on cell signal quality conditions will lead to problems such as high handover frequency and short cell dwell time. It is impossible to effectively add or switch primary and secondary cells based on non-terrestrial access networks, and it will also lead to unstable dual connectivity between the primary base station network and the non-terrestrial access network.

[0005] To address the aforementioned technical issues, this disclosure proposes a solution that can improve the effectiveness of adding or switching primary and secondary cells based on non-terrestrial access networks and enhance the stability of dual connectivity between the primary base station network and the non-terrestrial access network.

[0009] In some embodiments, the time condition includes at least one of timer timing, trigger time, and remaining service time of candidate primary and secondary cells, wherein the trigger time includes a trigger time point or a trigger time range.

[0026] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] Figure 1 This is a flowchart illustrating a primary and secondary cell processing method according to some embodiments of the present disclosure.

[0033] like Figure 1 As shown, the primary / secondary cell processing method includes: step S1, obtaining the configuration information and handover triggering conditions of at least one candidate primary / secondary cell; step S2, determining whether each candidate primary / secondary cell meets its corresponding triggering conditions; step S3, if at least one candidate primary / secondary cell meets its corresponding triggering conditions, selecting a target primary / secondary cell from the at least one candidate primary / secondary cell; and step S4, accessing the target primary / secondary cell according to its configuration information. The primary / secondary cell processing method is executed by the terminal.

[0034] In step S1, the configuration information (including configuration information for accessing the candidate primary / secondary cell group cell) and the triggering conditions required for handover are obtained from the primary base station for at least one candidate primary / secondary cell group cell (PSCell) corresponding to the secondary base station based on the non-terrestrial access network. The candidate primary / secondary cells overlap with the primary cell of the primary base station, and the primary and secondary base stations have data communication and interaction capabilities. In some embodiments, the terminal receives an RRC (Radio Resource Control) reconfiguration message from the primary base station. The RRC reconfiguration message includes the configuration information of each candidate primary / secondary cell and the triggering conditions required for handover. The triggering conditions include at least one of time conditions and location conditions, as well as cell signal quality conditions. The triggering conditions corresponding to each candidate primary / secondary cell are pre-configured in the primary base station.

[0035] In some embodiments, the time condition includes at least one of a timer, a trigger time, and the remaining service time of the candidate primary and secondary cells. The trigger time includes a trigger point or a trigger time range. For example, a time condition threshold can be set to help determine whether the time condition is met.

[0036] In some embodiments, the secondary base station broadcasts cells via satellite. Location conditions include the relative position between the terminal and the satellite (i.e., the satellite corresponding to the candidate primary / secondary cell). The relative position includes at least one of the following: the distance between the terminal and the satellite, the distance between the terminal and the coverage center of the candidate primary / secondary cell, and the geographical coverage area of ​​the candidate primary / secondary cell. For example, a location condition threshold can be set to help determine whether the location conditions are met.

[0037] In some embodiments, cell signal quality conditions include at least one of RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), and SINR (Signal to Interference plus Noise Ratio).

[0038] In some embodiments, the secondary base station is a satellite base station, and the terminal has GNSS (Global Navigation Satellite System) positioning capability.

[0039] In some embodiments, the primary base station is based on a terrestrial access network. In other embodiments, the primary base station is based on a non-terrestrial access network. When the primary base station is also based on a non-terrestrial access network, both the primary and secondary base stations can be high-Earth orbit (GEO) satellites, low-Earth orbit (LEO) satellites, or a combination of GEO and LEO satellites.

[0040] In some embodiments, the primary base station sends an indication message to the candidate secondary base stations in advance to request the candidate secondary base stations to pre-configure access resources for the terminal. That is, the candidate secondary base stations feed back the configuration information of the candidate primary and secondary cells to the primary base station. The primary base station sends an RRC reconfiguration message to the terminal, which contains the configuration information of at least one candidate primary and secondary cell and the triggering conditions required to hand over to each candidate primary and secondary cell.

[0041] Figure 2 A schematic diagram of the combination of a primary base station and a secondary base station in some embodiments of this disclosure is shown.

[0042] like Figure 2 As shown, the main base station is a terrestrial base station, based on a terrestrial access network. The secondary base station is based on a non-terrestrial access network and connects via... Figure 2 The satellites broadcast information to the cell. The ground cell coverage of the primary base station and the satellite cell coverage of the secondary base station overlap. The terminal can communicate with both the primary and secondary base stations simultaneously.

[0043] Figure 3 A schematic diagram of the combination of a primary base station and a secondary base station is shown in some other embodiments of this disclosure.

[0044] like Figure 3 As shown, both the primary and secondary base stations are based on a non-terrestrial access network and broadcast cells via Satellite 1 and Satellite 2, respectively. The coverage areas of the Satellite 1 cell corresponding to the primary base station and the Satellite 2 cell corresponding to the secondary base station overlap. The terminal can communicate with both the primary and secondary base stations simultaneously.

[0045] return Figure 1 In step S2, it is determined whether each candidate primary and secondary cell meets its corresponding triggering condition.

[0046] In some embodiments, it is determined whether the corresponding triggering condition is met based on the priority configuration relationship information between the triggering conditions corresponding to each candidate primary and secondary cell.

[0047] In some embodiments, if the triggering conditions corresponding to each candidate primary and secondary cell have the same priority, it is simultaneously determined whether the corresponding triggering conditions are met. If multiple triggering conditions are configured to have the same priority, the terminal evaluates all triggering conditions simultaneously, and only when the candidate secondary cell meets all triggering conditions simultaneously is it considered that the execution conditions for adding / handing over the secondary cell are met.

[0048] For example, if the triggering conditions for handover include location conditions and cell signal quality conditions, and these two triggering conditions have the same priority, then the terminal simultaneously measures the relative position between the terminal and the satellites corresponding to the candidate primary and secondary cells, as well as the reference signal quality of the candidate primary and secondary cells. In some embodiments, the relative position between the terminal and the satellites corresponding to the candidate primary and secondary cells can be calculated based on the terminal's positioning capabilities and satellite ephemeris.

[0049] In some embodiments, when the triggering conditions corresponding to each candidate primary and secondary cell have different priorities, the terminal determines whether the corresponding triggering conditions are met according to the order of priority. If multiple triggering conditions are configured with different priorities, the terminal evaluates the triggering conditions sequentially. When the first triggering condition is met, the second triggering condition is evaluated, and so on. Only when the candidate primary and secondary cells simultaneously meet all the triggering conditions is the condition for adding / handing over the primary / secondary cell considered met. By setting priorities, signaling overhead can be reduced, terminal power consumption can be lowered, and problems such as high handover frequency and short cell dwell time can be effectively solved, improving the stability of multiple connections and enhancing the user experience.

[0050] For example, the triggering conditions required for handover include location conditions and cell signal quality conditions, and the location conditions have a higher priority. Then, the terminal measures the relative position between the terminal and the satellites corresponding to the candidate primary and secondary cells, and only starts measuring the reference signal quality of the candidate primary and secondary cells when the location conditions are met.

[0051] For example, the triggering conditions required for handover include time conditions and cell signal quality conditions, and the time conditions have a higher priority. In this case, the terminal will start measuring the reference signal quality of the candidate primary and secondary cells only when it detects that the timer has expired or that a specific time has been met.

[0052] For example, the triggering conditions required for handover can also include time conditions, location conditions, and cell signal quality conditions simultaneously. The determination process is similar to the aforementioned embodiments and will not be repeated here.

[0053] In step S3, if at least one candidate primary / secondary cell meets its corresponding triggering condition, a target primary / secondary cell is selected from at least one candidate primary / secondary cell. For example, a candidate primary / secondary cell that meets the triggering condition can be randomly selected as the target primary / secondary cell, or the candidate primary / secondary cell with the strongest cell signal quality can be selected as the target primary / secondary cell. Those skilled in the art can make configuration adjustments according to the actual situation, which will not be elaborated here.

[0054] In step S4, the target primary and secondary cells are accessed according to their configuration information.

[0055] In some embodiments, if the terminal has already accessed the original primary or secondary cell before accessing the target primary or secondary cell, the terminal must also release the original primary or secondary cell. This primary / secondary cell handling process is a primary / secondary cell handover or change process.

[0056] In some embodiments, the terminal has not accessed any primary or secondary cells before accessing the target primary or secondary cell. In this case, the terminal directly accesses the target primary or secondary cell. The primary or secondary cell processing procedure is a primary or secondary cell addition process.

[0057] In some embodiments, after accessing the target primary and secondary cells, the terminal also notifies the primary base station that it has selected the target primary and secondary cells, meaning the terminal has applied the configuration of the target primary and secondary cells. For example, the terminal may send indication information containing relevant information about the target primary and secondary cells to the primary base station.

[0058] In the above embodiments, considering that the signal quality changes very little in the cell center and cell edge in the non-terrestrial access network scenario and that the satellite cell corresponding to the non-terrestrial access network has the characteristic of continuous movement relative to the Earth's surface, by adding at least one of time conditions and location conditions to the configuration information of candidate primary and secondary cells, the effectiveness of adding or switching primary and secondary cells based on the non-terrestrial access network is improved, and the stability of dual connectivity between the primary base station network and the non-terrestrial access network is improved.
