Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of communication technology, and particularly to a cell access method, a cell access device, a terminal, and a computer-readable storage medium. Background Technology

[0002] Carrier aggregation (CA) technology combines multiple component carriers (CCs) to support greater transmission bandwidth, thereby increasing the peak throughput of the user equipment (UE). CA is divided into downlink CA combinations and uplink CA combinations, and the number of CA combinations supported by a UE is limited. Generally, uplink CA combinations are a subset of downlink CA combinations. Therefore, in some cases, due to the frequency band of the initially registered cell, only downlink CA combinations may be activated, while uplink CA combinations may not be activated, thus affecting the UE's uplink rate. Summary of the Invention

[0003] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0004] This invention provides a cell access method, a cell access device, a terminal, and a computer-readable storage medium, which can improve the success rate of uplink CA combination activation and achieve the goal of increasing uplink speed.

[0013] The processing unit is used to compare the first frequency band information and the second frequency band information, and adjust the access weight of each cell according to the comparison result;

[0014] An access unit is used to select a target cell from among the multiple cells for access based on the access weight.

[0017] This invention includes a cell access method applied to a terminal. The method comprises the following steps: acquiring cell information of each cell, wherein the cell information includes first frequency band information; acquiring uplink CA combinations supported by the terminal and second frequency band information corresponding to the uplink CA combinations; comparing the first frequency band information and the second frequency band information, and adjusting the access weight of each cell according to the comparison result; and then selecting a target cell from multiple cells for access based on the adjusted access weights. According to the technical solution of this invention, when initially accessing the network, the terminal can calculate the access weight for each of the currently searched available cells based on its own uplink CA combination capability, and sequentially select a target cell from multiple cells to attempt access based on the access weight.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] In related technologies, with the development of communication technology, the number of mobile terminal users and throughput are increasing daily. However, since the carrier resources of a single cell are limited, when there are no idle carrier resources available in a cell, the users in that cell cannot reach the peak throughput that the users are capable of.

[0034] LTE (Long Term Evolution) is the long-term evolution of the UMTS (Universal Mobile Telecommunications System) technical standard developed by the 3GPP (3rd Generation Partnership Project) organization.

[0035] 3GPP introduced CA (Collaboration Capacitor) technology in Release 10. CA technology aggregates multiple CCs together to support greater transmission bandwidth, specifically up to 100MHz, thereby increasing the peak throughput of a single UE.

[0036] In carrier aggregation technology, the aggregated carriers consist of one PCC (Primary Component Carrier) and one or more SCCs (Secondary Component Carriers). Carrier aggregation includes downlink CA and uplink CA. Specifically, downlink CA increases downlink speed by aggregating multiple downlink carriers, while uplink CA increases uplink speed by aggregating multiple uplink carriers.

[0037] Specifically, carrier aggregation is a UE-level feature, and different UEs may have different sets of PCCs and SCCs. For a UE, at any given time, the UE has only one PCC, which is used for both uplink CA and downlink CA.

[0038] Furthermore, the CA combinations supported by a UE are often limited. In other words, not any combination of frequency bands supported by the UE can be used as a CA combination. The types of uplink CA combinations supported by a UE are often fewer than those of downlink CA combinations; uplink CA combinations are a subset of downlink CA combinations.

[0039] Before a CA can be activated and used, it must go through a series of processes, including: initial access, CA configuration, and CA activation, as detailed below:

[0040] During the initial access phase, the cell that the UE accesses is the serving cell. The UE reports its capabilities on this cell, including information such as supported frequency bands, downlink CA combinations, and uplink CA combinations. At this time, the carrier of the serving cell is the PCC.

[0041] During the CA configuration phase, the network sends SCC information currently supported by the network to the UE based on the UE's capabilities.

[0042] During the CA activation phase, the network activates the CA at an appropriate time via instructions from the MAC layer. Depending on whether it is uplink CA or downlink CA, after the corresponding CA is activated, the UE can transmit uplink or downlink data simultaneously on PCC and SCC, thereby achieving the goal of improving the data rate.

[0043] Based on the above description, it is possible that if a UE registers a cell as a PCC, it may be unable to configure and activate the uplink CA. An example is provided below:

[0044] If the network has three cells in the current environment, namely B1, B3, and B7, the UE supports the downlink CA combination of B1+B3+B7, and the uplink CA combination is only B1+B3. During the initial access phase, regardless of which cell the UE accesses (i.e., which cell is the PCC), the downlink B1+B3+B7 combination can be configured and activated. For example, if the initial access is to B1, then the cell of B1 is the PCC. The PCC then sends the information of cells B3 and B7 as the SCC information of the downlink CA to the UE, completing the configuration of the downlink CA combination B1+B3+B7; alternatively, the information of B3 can be sent to the UE as the SCC information of the uplink CA, completing the configuration of the uplink CA combination B1+B3. However, if the UE initially accesses cell B7, since the uplink CA combination supported by the UE is B1+B3 and does not include B7, the network cannot send uplink CA SCC information after the UE camps on cell B7. Therefore, the uplink CA cannot be activated, and the UE can only use cell B7 for uplink data transmission. As a result, the uplink CA combination of B1+B3 in the current environment cannot be utilized.

[0045] Therefore, the choice of the initial access cell for the UE may, under certain circumstances, determine whether the UE can activate the uplink CA combination, that is, whether it can fully utilize the uplink spectrum resources of the current environment to improve the uplink rate. In other words, there may be situations where, due to the frequency band of the initially accessed cell, only the downlink CA combination can be activated, but the uplink CA combination cannot be activated, thus affecting the UE's uplink rate.

[0046] Based on the above, embodiments of the present invention provide a cell access method, a cell access device, a terminal, and a computer-readable storage medium. The cell access method is applied to a terminal and includes, but is not limited to, the following steps: acquiring cell information of each cell, wherein the cell information includes first frequency band information; acquiring uplink CA combinations supported by the terminal and second frequency band information corresponding to the uplink CA combinations; comparing the first frequency band information and the second frequency band information, and adjusting the access weight of each cell according to the comparison result; and then selecting a target cell from multiple cells for access based on the adjusted access weight. According to the technical solution of the embodiments of the present invention, when initially accessing the network, the terminal can calculate the access weight for each of the currently searched available cells based on its own uplink CA combination capability, and sequentially select a target cell from multiple cells to attempt access based on the access weight. Therefore, through the above access process, the embodiments of the present invention enable the terminal to preferentially select cells that support uplink CA combinations as the initial access cell, thereby improving the success rate of activating uplink CA combinations and thus increasing the uplink speed.

[0047] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, Figure 1 This is a schematic diagram of a system architecture platform 100 for performing a cell access method according to an embodiment of the present invention.

[0049] exist Figure 1 In this example, the system architecture platform 100 includes a processor 110 and a memory 120, which can be connected via a bus or other means. Figure 1 Taking the example of a connection between China and Israel via a bus.

[0050] Memory 120, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory 120 may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, memory 120 may optionally include memory 120 remotely located relative to processor 110, and these remote memories can be connected to the system architecture platform via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0051] Those skilled in the art will understand that this system architecture platform can be applied to LTE communication network systems, 5G communication network systems, and subsequent evolved mobile communication network systems, etc., and this embodiment does not specifically limit it in this regard.

[0052] It will be understood by those skilled in the art that Figure 1 The system architecture platform shown does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0053] exist Figure 1 In the system architecture platform shown, processor 110 can call the cell access program stored in memory 120 to execute the cell access method.

[0054] Based on the above system architecture platform, various embodiments of the cell access method of the present invention are proposed below.

[0055] like Figure 2 As shown, Figure 2 This is a flowchart of a cell access method provided in an embodiment of the present invention. The method is applied to a terminal, i.e., a user equipment, and includes, but is not limited to, steps S100, S200, S300 and S400.

[0056] Step S100: Obtain cell information for each cell, wherein the cell information includes first frequency band information;

[0057] Step S200: Obtain the uplink CA combination supported by the terminal and the second frequency band information corresponding to the uplink CA combination;

[0058] Step S300: Compare the information of the first frequency band and the information of the second frequency band, and adjust the access weight of each cell according to the comparison result;

[0059] Step S400: Select the target cell from multiple cells for access based on the access weight.

[0060] Specifically, the terminal scans the cells in the current environment to obtain information on multiple available cells, each including but not limited to information on a first frequency band. Next, the terminal obtains one or more uplink CA combinations supported locally, each corresponding to information on a second frequency band. Then, the terminal compares the first and second frequency band information to obtain a comparison result, and adjusts the access weights of each cell based on this result, obtaining the adjusted access weights for each cell. Finally, based on the adjusted access weights of each cell, the terminal sequentially selects the target cell from the multiple cells in descending order of access weight to attempt access until successful access is achieved.

[0061] According to the technical solution of the embodiments of the present invention, when a terminal initially accesses the network, it can calculate the access weight for each of the currently searched available cells based on its own uplink CA combination capability, and sequentially select a target cell from multiple cells to attempt access based on the access weight. Therefore, through the above-described access process, the embodiments of the present invention enable the terminal to preferentially select cells that support uplink CA combination as the initial access cell, thereby improving the success rate of activating uplink CA combination and thus increasing the uplink speed.

[0062] It should be noted that, regarding the second frequency band information mentioned above, since each uplink CA combination is aggregated from one PCC and one or more SCCs, the second frequency band information will include frequency band information corresponding to two or more cells.

[0063] In addition, such as Figure 3 As shown, Figure 3 This is a flowchart illustrating the filtering process of cell information in a cell access method provided by an embodiment of the present invention. The cell information in this embodiment of the present invention also includes, but is not limited to, communication quality information. Before step S300, the cell access method in this embodiment of the present invention also includes, but is not limited to, step S500.

[0064] Step S500: When the communication quality information does not meet the preset communication quality requirements, filter the cell information.

[0065] Specifically, after the terminal scans the cells in the current environment and obtains information on multiple available cells, the terminal will also filter the obtained information on multiple cells, filtering out cells that do not meet the access conditions. For example, the terminal will filter out cells with poor signal and cells that are prohibited from access, etc.

[0066] In addition, such as Figure 4 As shown, Figure 4This is a flowchart illustrating the initialization of cell access weights in a cell access method according to an embodiment of the present invention. Prior to step S300, the cell access method of this embodiment of the present invention further includes, but is not limited to, step S600.

[0067] Step S600: Initialize the access weight of each cell to ensure that the access weight of each cell is consistent.

[0068] Specifically, since the terminal needs to sequentially select a target cell from multiple cells according to its access weight, in order to ensure the consistency and fairness of the access weights of each cell before adjusting them, this embodiment of the invention initializes the access weights of each cell before adjusting them, keeping the access weights of all cells consistent. For example, the access weights of all cells can be initialized so that the initial value of the access weights of all cells is 0.

[0069] In addition, such as Figure 5 As shown, Figure 5 This is a flowchart illustrating the comparison of first frequency band information and second frequency band information for each cell in a cell access method provided by an embodiment of the present invention. The comparison of the first frequency band information and second frequency band information in step S300 above includes, but is not limited to, step S700.

[0070] Step S700: For each cell, compare the cell's first frequency band information with the second frequency band information of each uplink CA combination in sequence.

[0071] Specifically, when there are multiple available cells in the current environment, in order to calculate the access weight of each cell, this embodiment of the invention needs to analyze and process each cell one by one. Meanwhile, the terminal may support one or more uplink CA combinations. Therefore, in this embodiment of the invention, for each cell, the terminal will sequentially compare the first frequency band information of that cell with the second frequency band information of each uplink CA combination.

[0072] For example, when there are two available cells and the terminal supports only one uplink CA combination, for the first cell, the terminal compares the first frequency band information of the first cell with the second frequency band information of the uplink CA combination, and adjusts the access weight of the first cell according to the comparison result. The adjusted access weight is the final access weight of the first cell. Similarly, for the second cell, the terminal compares the first frequency band information of the second cell with the second frequency band information of the uplink CA combination, and adjusts the access weight of the second cell according to the comparison result. The adjusted access weight is the final access weight of the second cell.

[0073] Additionally, for example, when there are two available cells and the terminal supports two uplink CA combinations, for the first cell, the terminal compares the first frequency band information of the first cell with the second frequency band information of the first uplink CA combination, and adjusts the access weight of the first cell based on the comparison result. Then, it compares the first frequency band information of the first cell with the second frequency band information of the second uplink CA combination, and adjusts the access weight of the first cell based on the comparison result. The adjusted access weight obtained after comparing the two uplink CA combinations is the final access weight of the first cell. Similarly, for the second cell, the terminal compares the first frequency band information of the second cell with the second frequency band information of the first uplink CA combination, and adjusts the access weight of the second cell based on the comparison result. Then, it compares the first frequency band information of the second cell with the second frequency band information of the second uplink CA combination, and adjusts the access weight of the second cell based on the comparison result. The adjusted access weight obtained after comparing the two uplink CA combinations is the final access weight of the second cell.

[0074] In addition, such as Figure 6 and Figure 7 As shown, Figure 6 This is a flowchart illustrating the adjustment of cell access weight based on a comparison result of first frequency band information and second frequency band information in a cell access method provided by an embodiment of the present invention. Figure 7 This is a flowchart illustrating the adjustment of cell access weight based on a comparison result of first frequency band information and second frequency band information in a cell access method provided in another embodiment of the present invention.

[0075] like Figure 6 As shown, step S300 above includes, but is not limited to, step S810.

[0076] Step S810: When the second frequency band information includes the first frequency band information, increase the access weight of the cell by a preset step size.

[0077] like Figure 7 As shown, step S300 above includes, but is not limited to, step S820.

[0078] Step S820: When the second frequency band information does not include the first frequency band information, reduce the access weight of the cell by a preset step size.

[0079] Specifically, the embodiments of the present invention can be adopted individually. Figure 6 The methods and steps in the text, or using them alone Figure 7 The methods and steps in the text, or simultaneously using Figure 6 and Figure 7 The methods and steps in the text.

[0080] It should be noted that the preset step size mentioned above can be 1, -1, or other values. For example, when the initial value of the cell's access weight is 0, if the second frequency band information includes the first frequency band information, the cell's access weight is increased by a preset step size of 1, so that the access weight is updated to 1.

[0081] In addition, such as Figure 8 As shown, Figure 8 This is a flowchart illustrating how a cell access method according to an embodiment of the present invention selects a target cell for access based on the access weight. Step S400 includes, but is not limited to, steps S910 and S920.

[0082] Step S910: Obtain the access priority of each cell based on the access weight.

[0083] Step S920: Select target cells for access in descending order of access priority until access is successful.

[0084] Specifically, after obtaining the access weight of each cell, the embodiments of the present invention will use the access weight as the sorting basis for access priority, and then attempt to access in order of access priority.

[0085] It is understandable that the higher the access weight of a cell, the higher the success rate of activating the uplink CA combination; conversely, the lower the access weight of a cell, the lower the success rate of activating the uplink CA combination. Therefore, in this embodiment of the invention, cells are selected in order of access priority from high to low to attempt access.

[0086] In addition, such as Figure 9 As shown, Figure 9 This is a flowchart illustrating the cell sorting according to access priority in a cell access method provided by an embodiment of the present invention. Step S920 described above includes, but is not limited to, steps S1010 and S1020.

[0087] Step S1010: Sort the multiple cells according to their access priority from high to low to obtain the sorted cells;

[0088] Step S1020: Based on the sorted multiple cells, select the target cell in sequence for access until access is successful.

[0089] Based on the above Figures 2 to 9 The following presents various embodiments of the cell access device of the present invention.

[0090] like Figure 10 As shown, Figure 10This is a schematic diagram of the structure of a cell access device provided in an embodiment of the present invention. The cell access device 200 of the present invention includes, but is not limited to, a scanning unit 210, a storage unit 220, a processing unit 230, and an access unit 240.

[0091] Specifically, the scanning unit 210 is used to acquire cell information of each cell, wherein the cell information includes first frequency band information; the storage unit 220 is used to acquire the uplink CA combination supported by the terminal and the second frequency band information corresponding to the uplink CA combination; the processing unit 230 is used to compare the first frequency band information and the second frequency band information, and adjust the access weight of each cell according to the comparison result; the access unit 240 is used to select a target cell from multiple cells for access according to the access weight.

[0092] In addition, the cell information also includes communication quality information. When the communication quality information does not meet the preset communication quality requirements, the processing unit 230 of this embodiment of the invention is also used to filter the cell information.

[0093] In addition, the processing unit 230 in this embodiment of the invention is also used to initialize the access weight of each cell so that the access weight of each cell remains consistent.

[0094] In addition, the processing unit 230 of this embodiment of the invention is also used to compare the first frequency band information of the cell and the second frequency band information of each uplink CA combination for each cell in turn.

[0095] In addition, when the second frequency band information includes the first frequency band information, the processing unit 230 of this embodiment of the invention is also used to increase the access weight of the cell by a preset step size.

[0096] In addition, when the second frequency band information does not include the first frequency band information, the processing unit 230 of this embodiment of the invention is also used to reduce the access weight of the cell by a preset step size.

[0097] In addition, the access unit 240 in this embodiment of the invention is also used to obtain the access priority of each cell according to the access weight, and select the target cell for access in descending order of access priority until the access is successful.

[0098] In addition, the access unit 240 of this embodiment of the invention also sorts multiple cells according to access priority from high to low to obtain multiple sorted cells, and selects a target cell for access in sequence according to the multiple sorted cells until access is successful.

[0099] Based on the above Figures 2 to 9 Cell access methods and Figure 10 The present invention relates to a cell access device, and below presents a general embodiment of the cell access method of the present invention.

[0100] like Figure 11 As shown, Figure 11 This is a general flowchart of a cell access method provided in an embodiment of the present invention. The cell access method of the present invention includes, but is not limited to, steps S1110, S1120, S1130, S1140, S1150, S1160, C110, S1170, C120, C130, S1180, S1190, and S1200.

[0101] S1110: The scanning unit scans the cells in the current environment to obtain a list of available cell information L1.
