Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a cell access method and device. Background Art

[0002] With the rapid development of communication technology, terminal devices are increasingly used in people's lives. Communication experience is one of the core competitiveness of terminal devices, and one of the main reasons affecting communication experience is cell optimization; illustratively, cell optimization includes at least one of cell switching, cell reselection, cell residence and cell reconstruction.

[0003] Currently, the cell selection operation is usually implemented based on a communication map pre-built by a network device. The communication map indicates the signal strength between the terminal device and different cells under the network device when the terminal device is at different locations. Thus, the terminal device can select an access cell based on the communication map.

[0004] However, with the development of communication technology, communication scenarios are becoming more and more complex, and the above communication maps can no longer meet the access requirements of terminal devices in complex communication scenarios. Summary of the invention

[0005] The cell access method and device provided in the embodiments of the present application can meet the access requirements of terminal devices in complex communication scenarios.

[0006] In a first aspect, a cell access method is provided, which can be executed by a first device, or by a component of the first device, such as a processor, a chip, or a chip system of the first device, or by a logic module or software that can implement all or part of the functions of the first device. The method includes: the first device receives first information from a second device, the first information is used to indicate first cell information, and the communication quality of N types of tasks corresponding to the first cell in M time periods, and indicates second cell information, and the communication quality of N types of tasks corresponding to the second cell in M time periods, wherein M and N are both positive integers; the first device determines to access the first cell or the second cell based on the first information and the current task type of the first device, and the N types of tasks include the current task type.

[0007] Based on this solution, the first device can receive the communication quality between the first device and different cells at different task types and different access times indicated by the second device; for example, the communication quality of N types of tasks in the first cell within M time periods, and the communication quality of N types of tasks in the second cell within M time periods. Further, based on information such as the current task type and the time to select the access cell, the access cell can be selected. For example, the first device can select the cell with the best communication quality corresponding to information such as the current task type and the time to access the cell. Compared with the solution of selecting the access cell based on the communication map including signal strength, it can provide differentiated assistance for different tasks at different times, thereby improving the optimization degree of cell selection and enhancing the user experience.

[0008] In a possible design, the first cell can be a partial range of the third cell; the first device determining to access the first cell or the second cell includes: the first device determining to access the third cell or the second cell.

[0009] Based on this possible design, since the first device needs to select one of the third cell and the second cell to access, the third cell and the second cell are respectively the basic units provided by different network devices for the first device to provide coverage; therefore, the coverage ranges of the third cell and the second cell are respectively the coverage ranges of their respective network devices. It can be understood that for some of the N types of tasks at different positions within the coverage range of the network device, the corresponding communication quality changes greatly. Therefore, in order to maintain the stability of the communication quality within a range, for this part of the tasks, the corresponding communication quality can be determined for different values within the coverage range of the network device, that is, the coverage range of the network device (such as the third cell) is divided into multiple sub-ranges, and each range corresponds to a sub-cell (such as the first cell), so that the communication quality corresponding to each sub-cell is relatively stable, thereby improving the accuracy of the first information and the accuracy of cell access.

[0010] In a possible design, the cell access method further includes: the first device also determines to access the third cell or the second cell based on the current position of the first device.

[0011] Based on this possible design, for the third cell, at different positions at the same moment, the communication quality of a certain type of task may be different; therefore, the first device can also determine a unique communication quality from the multiple communication qualities corresponding to each of the M time periods of a certain type of task in the third cell based on the current position of the first device, and then use this unique communication quality as the communication quality of this task in the third cell at the current moment to participate in determining the access cell; for example, the first device can select the cell with the best communication quality corresponding to this type of task among the third cell and the second cell, so as to improve the goodness of cell preference for this type of task and enhance the user experience.

[0012] In a possible design, before the first device receives the first information, the cell access method further includes: the first device sends second information to the second device, and the second information includes communication parameters of N types of tasks in M time periods respectively, and the communication parameters are used to determine the first information.

[0013] In a second aspect, a cell access method is provided. This method can be executed by the second device, or by components of the second device, such as the processor, chip, or chip system of the second device, etc., and can also be implemented by a logic module or software that can implement all or part of the functions of the second device. The method includes: the second device sends first information to the first device, where the first information is used to indicate the first cell information, and the communication qualities of N types of tasks corresponding to the first cell in M time periods respectively, and to indicate the second cell information, and the communication qualities of N types of tasks corresponding to the second cell in M time periods respectively, and both M and N are positive integers; the first information is further used for the first device to determine whether to access the first cell or the second cell.

[0014] Based on this solution, the second device can inform the first device of the communication qualities between the first device and different cells at different task types and different access times; for example, the communication qualities of N types of tasks in the first cell in M time periods respectively, and the communication qualities of N types of tasks in the second cell in M time periods respectively. Thus, the first device can select the access cell based on information such as the current task type and the time to select the access cell. For example, the first device can select the cell with the best communication quality corresponding to information such as the current task type and the time to select the access cell. Compared with the solution of selecting the access cell based on the communication map including signal strength, it can provide differentiated assistance for different tasks at different time periods, thereby improving the goodness of cell preference and enhancing the user experience.

[0015] In a possible design, before the second device sends the first information, the cell access method further includes: the second device generates the first information.

[0016] Based on this possible design, the second device may determine the first information based on the communication parameters of N types of tasks indicated by the second information in M time periods respectively, providing a basic guarantee for the first device to determine the access cell based on the first information.

[0017] In a possible design, before the second device sends the first information, the cell access method further includes: receiving the first information from a third device.

[0018] In a possible design, before the second device sends the first information, the cell access method further includes: the second device receives the second information from the first device, where the second information includes the communication parameters of N types of tasks in M time periods respectively, and the communication parameters are used to determine the first information.

[0019] In a possible design, after the second device receives the second information, the cell access method further includes: sending the second information to a third device.

[0020] Based on the above three possible designs, the third device may determine the first information based on the communication parameters of N types of tasks indicated by the second information in M time periods respectively. Exemplarily, the third device may be a cloud. Since the cloud has greater computing power compared to a base station, therefore, the accuracy of the first information determined based on the third device is higher and the operation delay is lower, thereby improving the efficiency of cell access.

[0021] In a possible design, the first cell is a partial range of the third cell; the first information is further used for the first device to determine access to the first cell or the second cell, including: the first information is further used for the first device to determine access to the third cell or the second cell.

[0022] Among them, the technical effects brought by any design in the second aspect can refer to the corresponding technical effects in the first aspect above, and will not be elaborated here.

[0023] In a third aspect, a cell access method is provided. This method may be executed by a third device, or by components of the third device, such as the processor, chip, or chip system of the third device, etc., or may also be implemented by a logic module or software that can implement all or part of the functions of the third device. The method includes: the third device generates the first information, where the first information is used to indicate the first cell information and the communication quality of N types of tasks corresponding to the first cell in M time periods respectively, and to indicate the second cell information and the communication quality of N types of tasks corresponding to the second cell in M time periods respectively, and both M and N are positive integers; the first information is further used for the first device to determine access to the first cell or the second cell; the third device sends the first information to the second device.

[0024] Based on this solution, the third device can generate the first information; for example, the third device can be the cloud. Since the cloud has greater computing power compared to the base station, the accuracy of the first information determined based on the third device is higher and the operation delay is lower, thus improving the efficiency of cell access.

[0025] In a possible design, before the third device generates the first information, the cell access method further includes: the third device receives the second information from the second device, and the second information includes the communication parameters of N types of tasks in M time periods, and the communication parameters are used to determine the first information.

[0026] Among them, the technical effects brought by any design in the third aspect can refer to the corresponding technical effects in the above first aspect or second aspect, and will not be elaborated here.

[0027] Combined with the first aspect, the second aspect or the third aspect, in a possible design, the first device can be a terminal device, the second device can be a network device, and the third device can be the cloud.

[0028] Combined with the first aspect, the second aspect or the third aspect, in a possible design, the first information indicates the first cell information, and the communication quality of N types of tasks corresponding to the first cell in M time periods, and indicates the second cell information, and the communication quality of N types of tasks corresponding to the second cell in M time periods, including: indicating the relationship between the communication quality of some of the N types of tasks in M time periods and the communication quality of the remaining tasks of the N types of tasks in M time periods.

[0029] Based on this optional solution, the first information includes the communication quality of some of the N types of tasks corresponding to multiple cells in M time periods, and the relationship between the communication quality of some tasks and the remaining tasks corresponding to multiple cells in M time periods. Compared with the solution where the second device directly sends the communication quality of N types of tasks corresponding to multiple cells in M time periods to the first device, the relationship between the communication quality of some tasks and the remaining tasks occupies less resources, thus saving communication and storage overhead.

[0030] Combined with the first aspect, the second aspect or the third aspect, in a possible design, the value of M corresponding to the first type of task is greater than the value of M corresponding to the second type of task, and the degree to which the first type of task is affected by network quality is greater than the degree to which the second type of task is affected by network quality, and the N types of tasks include the first type of task and the second type of task.

[0031] Based on this possible example, it can be understood that for some of the N types of tasks, the corresponding communication quality varies greatly during any one of the M time periods. Therefore, in order to maintain the stability of the communication quality within a time period, for these tasks, the duration of each of the M time periods can be shortened. That is to say, for some tasks, the duration of each of the corresponding M time periods is shorter. Thus, when the total duration corresponding to each task is the same, the value of M corresponding to some tasks is greater than the value of M corresponding to the remaining tasks. Thereby improving the accuracy of the first information and the accuracy of cell access.

The communication device can be any one of the first device in the first aspect, the second device in the second aspect, or the third device in the third aspect, or a device included in any one of the first device, the second device, or the third device, such as a chip or a chip system.

The transceiver module can include a receiving module and a transmitting module, which are respectively used to implement the receiving function and the transmitting function in any of the above aspects and any possible implementation manners thereof.

[0034] In some possible designs, the transceiver module can be composed of a transceiver circuit, a transceiver, a transceiver, or a communication interface.

[0035] In a fifth aspect, a communication device is provided, including: a processor and a memory; the memory is used to store computer instructions, and when the processor executes the instructions, the communication device is caused to execute the methods described in any of the above aspects.

The communication device can be any one of the first device in the first aspect, the second device in the second aspect, or the third device in the third aspect, or a device included in any one of the first device, the second device, or the third device, such as a chip or a chip system.

[0062] With the rapid development of communication technology, terminal devices are more and more widely used in people's lives. Communication experience is one of the core competitiveness of terminal devices, and one of the main reasons affecting communication experience is cell selection optimization; exemplarily, cell selection optimization includes at least one of cell handover, cell reselection, cell residence, and cell reconstruction.

[0063] The radio access network (RAN) resource configurations of different networks are different, the network loads are different, and the coverage and interference are different, so the experiences provided for different task types are also different. For example, characteristics such as network load usually have periodic changes, that is, at different moments within a period, the load of the same network is different.

[0064] Currently, the operation of cell selection optimization is usually implemented based on a communication map pre-constructed by a network device. The communication map indicates the signal strengths between a terminal device and different cells under the network device at different positions. Thus, the terminal device can select an access cell based on this communication map.

[0065] However, in the solution of selecting an access cell based on the above communication map, on the movement path of the terminal device, regardless of different task types and different access moments, the cell finally accessed by the terminal device is always the same cell. Therefore, this solution cannot meet the access requirements of terminal devices in complex communication scenarios (such as cell selection optimization scenarios at different moments and different task types).

[0066] Based on this, the embodiments of the present application provide a cell access method and apparatus, where a second device informs a first device of the communication quality between the first device and different cells at different task types and different access times; for example, the communication quality of N types of tasks in M time periods of the first cell and the communication quality of N types of tasks in M time periods of the second cell. Thus, the first device can select the cell to access based on information such as the current task type and the time to select the access cell. For example, the first device can select the cell with the best communication quality corresponding to information such as the current task type and the time to access the cell. Compared with the solution of selecting the access cell based on the communication map including the signal strength, it can provide differentiated assistance for different tasks at different times, thereby improving the goodness of cell preference and enhancing the user experience.

[0067] The technical solution provided by this application can be used in various communication systems, which can be 3rd generation partnership project (3GPP) communication systems. For example, 4th generation (4G) long term evolution (LTE) systems, evolved LTE systems (LTE-Advanced, LTE-A) systems, 5th generation (5G) new radio (NR) systems, vehicle to everything (V2X) systems, systems with hybrid networking of LTE and NR, or device-to-device (D2D) systems, machine to machine (M2M) communication systems, Internet of Things (IoT), LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication systems, and other next-generation communication systems, such as 6th generation (6G) communication systems, etc. Alternatively, the communication system can also be a non-3GPP communication system, such as a WLAN communication system, that is, the communication system can be applicable to the IEEE 802.11 system standard, for example, 802.11a / b / g standards, 802.11n standards, 802.11ac standards, 802.11ax standards, or their next generations, such as 802.11be standards or even more next-generation standards.

[0088] It should be noted that the communication system described in the embodiments of the present application is for more clearly explaining the technical solutions of the embodiments of the present application and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0089] The following describes the cell access method provided in the embodiments of the present application in conjunction with the accompanying drawings. It should be noted that in the following embodiments of the present application, the message names between devices, the names of various parameters, or the names of various information are only examples, and in other embodiments, they may also be other names. The method provided in the present application does not make specific limitations on this.

[0090] It can be understood that in the embodiments of the present application, the execution subject may execute some or all of the steps in the embodiments of the present application. These steps or operations are only examples, and the embodiments of the present application may also execute other operations or various deformations of the operations. In addition, each step may be executed in a different order presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application need to be executed.

[0091] See Figure 3 , which is a flowchart of a cell access method provided in the embodiments of the present application. The cell access method may include the following steps S301 to S302.

[0092] S301. The second device sends the first information to the first device. Correspondingly, the first device receives the first information from the second device.

[0093] Among them, the first information is used to indicate the first cell information and the communication quality of N types of tasks corresponding to the first cell in M time periods, and to indicate the second cell information and the communication quality of N types of tasks corresponding to the second cell in M time periods, where M and N are both positive integers.

[0094] Exemplarily, the first cell information includes the identifier (ID) of the first cell. Correspondingly, the second cell information includes the ID of the second cell.

[0095] Exemplarily, the communication quality of N types of tasks corresponding to the first cell in M time periods can be understood as: the communication quality of each type of task among the N types of tasks of the first cell in each of the M time periods. Similarly, the communication quality of N types of tasks corresponding to the second cell in M time periods can be understood as: the communication quality of each type of task among the N types of tasks of the first cell in each of the M time periods.

[0096] Exemplarily, the communication quality includes but is not limited to the quality of experience (QoE) of the user.

[0097] Optionally, the duration corresponding to each of the M time periods is the same.

[0098] Optionally, the first cell and the second cell are respectively cells within the coverage ranges of different network devices, that is, the first cell and the second cell respectively belong to different network devices.

[0099] Exemplarily, the second device may be a network device belonging to the first cell, or the second device may be a network device belonging to the second cell, or the second device may be other network devices other than the network device belonging to the first cell and the network device belonging to the second cell.

[0100] Optionally, the first information may further indicate cell information other than the first cell information and the second cell information. Correspondingly, the first information may further indicate the communication quality of N types of tasks corresponding to other cells in M time periods respectively; therefore, it can be considered that the first information can indicate the cell information of different cells, and the communication quality of N types of tasks corresponding to each cell in different cells in M time periods respectively. That is, the first information can indicate multiple cell information, and the communication quality of N types of tasks corresponding to each cell in multiple cells in M time periods respectively, where the multiple cells include the first cell and the second cell. The communication quality of N types of tasks corresponding to each cell in multiple cells in M time periods respectively includes: the communication quality of N types of tasks corresponding to the first cell in M time periods respectively, and the communication quality of N types of tasks corresponding to the second cell in M time periods respectively. Wherein, the multiple cells (or different cells) include the first cell and the second cell.

[0101] Exemplarily, taking the multiple cells including 10 cells (such as cell #1 to cell #10) as an example, that is, the first information indicates cell #1 and the communication quality of N types of tasks corresponding to cell #1 in M time periods respectively, cell #2 and the communication quality of N types of tasks corresponding to cell #2 in M time periods respectively,..., cell #10 and the communication quality of N types of tasks corresponding to cell #10 in M time periods respectively.

[0102] S302. The first device determines to access the first cell or the second cell based on the first information and the current task type of the first device, and the N types of tasks include the current task type.

[0103] Exemplarily, the first device may, based on the current task type, select one of the communication qualities of the task type indicated in the first information in M time periods respectively, and determine to access the cell corresponding to the communication quality. For example, the communication quality may be the best communication quality of the task type indicated in the first information in M time periods respectively.

[0104] Optionally, the first device determines to access the first cell or the second cell based on the first information and the current task type of the first device, including: the first device determines to access the first cell or the second cell based on the first information, the current task type of the first device, and the current time period.

[0105] Exemplarily, the first device may, based on the current task type, select one of the communication qualities in the communication qualities of the task type indicated by the first information during the current period, and determine to access the cell corresponding to the selected communication quality. For example, the communication quality may be the best communication quality among the communication qualities of the task type indicated by the first information during the current period.

[0106] Optionally, the first device may also combine the local information of the first device to determine whether to access the first cell or the second cell. That is, the first device may determine whether to access the first cell or the second cell based on the first information, the current task type of the first device, and the local information of the first device.

[0107] Exemplarily, the local information includes, but is not limited to, the signal strength between the first device and the network device to which the first cell belongs, and the signal strength between the first device and the network device to which the second cell belongs. For example, the first device may select to access the cell with the strongest signal strength, the best communication quality corresponding to the current task type, and the best communication quality.

[0108] Optionally, when the multiple cells are the first cell and the second cell, the first device may determine whether to access the first cell or the second cell based on the first information and the current task type of the first device; when the number of cells included in the multiple cells is greater than 2 and the multiple cells include the first cell and the second cell, the first device may determine to access one of the multiple cells based on the first information and the current task type of the first device.

[0109] Exemplarily, when the multiple cells include cell #1 and cell #2, the first device may select the cell to access from cell #1 and cell #2, that is, the first device may determine whether to access cell #1 or cell #2 based on the first information and the current task type of the first device; when the multiple cells include cell #1, cell #2, and cell #3, the first device may select the cell to access from cell #1, cell #2, and cell #3, that is, the first device may determine to access one of cell #1, cell #2, or cell #3 based on the first information and the current task type of the first device.

[0110] An embodiment of this application provides a cell access method, where a second device informs a first device of the communication quality between the first device and different cells at different task types and different access times; for example, the communication quality of N types of tasks in the first cell within M time periods, and the communication quality of N types of tasks in the second cell within M time periods. Thus, the first device can select the cell to access based on information such as the current task type and the time to select the access cell. For example, the first device can select the cell with the best communication quality corresponding to information such as the current task type and the time to access the cell. Compared with the solution of selecting the access cell based on the communication map including the signal strength, it can provide differential assistance for different tasks at different times, thereby improving the optimality of cell preference and enhancing the user experience.

[0111] The above is the overall description of the cell access method provided by the embodiment of this application. Next, a detailed description of the "first information" involved in the above embodiment will be given.

[0112] Optionally, the communication quality of N types of tasks in the i-th cell indicated by the first information within M time periods can be understood as: within each of the M time periods, each of the N types of tasks corresponds to a communication quality; that is to say, the communication quality corresponding to the i-th cell includes M*N communication qualities. Among them, the communication quality corresponding to the i-th cell can be understood as: among the communication qualities indicated by the first information, the communication quality related to the i-th cell; that is, the communication quality of N types of tasks in the i-th cell within M time periods. i = 1, 2,..., X, where X is the number of cells of multiple cells.

[0113] Exemplarily, taking the first information including the communication quality of N types of tasks in each cell among multiple cells within M time periods as an example, the M*N communication qualities corresponding to the i-th cell included in the first information can be the content shown in Table 1 below:

[0114] Table 1

[0115]

[0116] Optionally, the communication quality corresponding to each of the N types of tasks includes X*M communication qualities. Among them, the communication quality corresponding to each type of task can be understood as: among the communication qualities indicated by the first information, the communication quality related to this type of task; that is, the communication quality of this type of task in each cell within M time periods.

[0117] Exemplarily, taking the first information including the communication quality of each of the N types of tasks in each cell among multiple cells within M time periods as an example, the X*M communication qualities corresponding to any one of the N types of tasks included in the first information can be the content shown in Table 2 below:

[0118] Table 2

[0119]

[0120] Optionally, in this possible implementation manner, the communication quality corresponding to each of the M time periods includes X * N communication qualities. Among them, the communication quality corresponding to each time period can be understood as: among the communication qualities indicated by the first information, the communication qualities related to this time period; that is, the communication qualities of the N types of tasks corresponding to each cell within this time period.

[0121] Exemplarily, taking the first information including the communication quality of each type of task among the N types of tasks in each of the M time periods in each of the multiple cells as an example, the X * N communication qualities corresponding to any one of the time periods included in the first information can be as shown in Table 3 below:

[0122] Table 3

[0123] Cell i Task #1 Task #2 … Task #N First cell Communication quality #1 Communication quality #2 … Communication quality #N Second cell Communication quality #N + 1 Communication quality #N + 2 … Communication quality #2N … … … … … Cell X Communication quality #(X - 1)*N + 1 Communication quality #(X - 1)*N + 2 … Communication quality #X*N

[0124] Based on the above three optional solutions, among the communication qualities of the N types of tasks corresponding to the i-th cell indicated by the first information in the M time periods, within each of the M time periods, each of the N types of tasks corresponds to one communication quality. Therefore, the first device can select the cell to access based on its task type and the time when it selects to access the cell, so as to provide differentiated assistance for different tasks in different time periods, thereby improving the optimization degree of cell preference and enhancing the user experience.

[0125] Combined with the above three optional solutions, the first information may include the following four possible implementation manners:

[0126] As the first possible implementation manner, the coverage areas of some of the multiple cells are of different sizes.

[0127] Optionally, some cells may include cells with a coverage area that is a partial range of the coverage area of its affiliated network device, and cells with a coverage area that is the coverage area of its affiliated network device; therefore, it can be considered that some cells include sub-cells and cells. Optionally, since for some of the N types of tasks, at different positions within the coverage area of the network device, the corresponding communication quality changes greatly, or some tasks are more significantly affected by the network quality at different positions within the coverage area of the network device. Therefore, in order to maintain the stability of the communication quality within a range, the coverage area of the network device can be divided into multiple sub-ranges, and each range corresponds to a sub-cell, so that the communication quality corresponding to each sub-cell is relatively stable.

[0128] For the remaining tasks in the N types of tasks, at different positions within the coverage of the network device, the corresponding communication quality changes less, or the remaining tasks are less affected by the network quality at different positions within the coverage of the network device. That is, within the coverage of the network device, the communication quality of this task is relatively stable. Therefore, for this task, there is no need to divide the coverage of the network device into multiple sub-ranges, or rather, the communication quality corresponding to each sub-range (or sub-cell) within the coverage of this network device is the same.

[0129] It should be understood that a sub-cell is a concept of a geographical area; a cell is a basic unit that provides coverage services for terminal devices in wireless communication; therefore, in wireless communication, a terminal device cannot directly access a sub-cell, but accesses the cell that includes the coverage of this sub-cell, that is, accesses the cell to which this sub-cell belongs; that is to say, when a terminal device accesses a sub-cell, it can be understood that: the terminal device accesses the cell to which this sub-cell belongs.

[0130] Optionally, taking some cells including the first cell as an example, the first cell can be a partial range of the third cell. At this time, the sub-cell includes the first cell, and the cell includes the third cell and the second cell; that is to say, the cell to which the first cell belongs is the third cell. Therefore, step S302 can be replaced with: the first device determines to access the third cell or the second cell based on the first information and the current task type of the first device.

[0131] Optionally, the third cell further includes a fourth cell, and the fourth cell can be a partial range of the third cell. Further, the coverage of the fourth cell is the same size as the coverage of the first cell, and the coverage of the fourth cell is different from the coverage of the first cell. That is to say, both the first cell and the fourth cell are sub-cells, and the first cell and the fourth cell belong to the same network device (i.e., the network device to which the third cell belongs), or both the first cell and the fourth cell belong to the third cell.

[0132] Exemplarily, since the third cell includes multiple sub-cells, therefore, for the third cell, in each of the M time periods, each of the N tasks corresponds to multiple communication qualities; at this time, the first device can determine the coverage of the sub-cell to which the current position belongs among the coverages of the multiple sub-cells based on the current position of the first device, and compare the communication quality of the current task type of this sub-cell in this time period with the communication quality of the current task type of the second cell in this time period, so as to determine whether to access the third cell or the second cell. That is to say, the parameter of the current position of the first device is also required in the process of determining whether to access the third cell or the second cell; that is, the cell access method described in the embodiments of the present application further includes: the first device also determines to access the third cell or the second cell based on the current position of the first device.

[0133] Exemplarily, taking the sub - cells including the first cell and the fourth cell, and the cells including the third cell and the second cell as an example, that is, multiple cells include the first cell, the second cell, and the fourth cell, that is, the value of X is 3. At this time, the first information may include the content shown in Table 4 below. Further, any one time period included in the first information corresponds to 3N communication qualities, which can be the content shown in Table 4 below. That is to say, the above Table 3 can be replaced with the content shown in Table 4 below:

[0134] Table 4

[0135]

[0136] Based on this possible implementation, it can be understood that for some of the N types of tasks at different positions within the coverage area of the network device, the corresponding communication quality changes greatly. Therefore, in order to maintain the stability of the communication quality within a range, for this part of the tasks, the corresponding communication quality can be determined for different values within the coverage area of the network device. That is, the coverage area of the network device is divided into multiple sub - ranges, and each range corresponds to a sub - cell, so that the communication quality corresponding to each sub - cell is relatively stable, thereby improving the accuracy of the first information and the accuracy of cell access.

[0137] As a second possible implementation, the value of M corresponding to some of the N types of tasks is different from the value of M corresponding to the remaining tasks.

[0138] Optionally, for some of the N types of tasks, within any one of the M time periods, the corresponding communication quality changes greatly, or for some tasks at different moments within a certain time period, the influence of network quality is more obvious. Therefore, in order to maintain the stability of the communication quality within a time period, the duration of each of the M time periods can be reduced. That is to say, for some tasks, the duration of each of the M time periods corresponding to them is shorter. For the remaining tasks, within any one of the M time periods, the corresponding communication quality changes less, or for the remaining tasks at different moments within a certain time period, the influence of network quality is less. Therefore, there is no need to reduce the duration of each of the M time periods. Thus, the value of M corresponding to some tasks is different from the value of M corresponding to the remaining tasks. Further, when the total duration corresponding to each task is the same, the value of M corresponding to some tasks is greater than the value of M corresponding to the remaining tasks.

[0139] Optionally, taking some tasks including the first - type tasks and the remaining tasks including the second - type tasks as an example, the value of M corresponding to the first - type tasks is greater than the value of M corresponding to the second - type tasks, and the degree to which the first - type tasks are affected by network quality is greater than the degree to which the second - type tasks are affected by network quality.

[0140] Exemplarily, taking the first information including the communication quality of the first type of tasks and the second type of tasks corresponding to multiple cells in M time periods as an example, that is, the value of N is 2. Since the value of M corresponding to the first type of tasks is different from the value of M corresponding to the second type of tasks, the value of M corresponding to the first type of tasks can be M1, and the value of M corresponding to the second type of tasks can be M2. Taking M1 as twice of M2 as an example, at this time, the first information can include the content shown in Table 5 below. That is to say, the above Table 1 can be replaced by the content shown in Table 5 below. Among them, the first information includes the communication quality of the first type of tasks corresponding to any one of the multiple cells in M1 time periods, and the first information includes the communication quality of the second type of tasks corresponding to any one of the multiple cells in M2 time periods.

[0141] Table 5

[0142]

[0143] Based on this possible implementation, it can be understood that for some of the N types of tasks, the change in their corresponding communication quality is relatively large in any one of the M time periods. Therefore, in order to maintain the stability of the communication quality in one time period, for these parts of tasks, the duration of each of the M time periods can be reduced. That is to say, for some tasks, the duration of each of the M time periods corresponding to them is shorter. Thus, when the total duration corresponding to each task is the same, the value of M corresponding to some tasks is greater than the value of M corresponding to the remaining tasks. Thereby improving the accuracy of the first information and the accuracy of cell access.

[0144] As a third possible implementation, the coverage ranges of some of the multiple cells are different in size. And the value of M corresponding to some of the N types of tasks is different from the value of M corresponding to the remaining tasks.

[0145] Exemplarily, the implementation of the coverage ranges of some of the multiple cells being different in size is the same as the implementation of the coverage ranges of some of the multiple cells being different in size in the above-mentioned first possible implementation. Specifically, it can refer to the relevant description in the above-mentioned first possible implementation; the implementation of the value of M corresponding to some of the N types of tasks being different from the value of M corresponding to the remaining tasks is the same as the implementation of the value of M corresponding to some of the N types of tasks being different from the value of M corresponding to the remaining tasks in the above-mentioned second possible implementation. Specifically, it can refer to the relevant description in the above-mentioned second possible implementation; details are not described herein again.

[0146] As a fourth possible implementation, the coverage ranges of each of the multiple cells are the same in size; and the value of M corresponding to each of the N types of tasks is the same.

[0147] As a first example, in this possible implementation, multiple cells respectively belong to different network devices.

[0148] Optionally, in this example, step S302 may be replaced with: The first device determines to access one of the multiple cells based on the first information and the current task type of the first device.

[0149] Optionally, in this example, the coverage range of each of the multiple cells is the coverage range of its affiliated network device.

[0150] As a second example, in this possible implementation, some of the multiple cells belong to the same network device.

[0151] Exemplarily, since some of the cells belong to the same network device, therefore, the coverage range of each of some of the cells is a partial range of the coverage range of its affiliated network device. Since the coverage range sizes of each of the multiple cells are the same, therefore, it can be considered that the coverage range of each of the multiple cells is a partial range of the coverage range of its affiliated network device.

[0152] It can be understood that a sub-cell can be understood as: a cell whose coverage range is a partial range of the coverage range of its affiliated network device; a cell can be understood as: a cell whose coverage range is the coverage range of its affiliated network device; for example, as Figure 6 shown, the coverage ranges of sub-cell #1 to sub-cell #5 can form the coverage range of cell #1, that is, the coverage range of any one of sub-cell #1 to sub-cell #5 is a partial range of the coverage range of cell #1.

[0153] Therefore, in this example, the multiple cells actually refer to multiple sub-cells. Further, the first information indicates the communication quality of N types of tasks corresponding to the multiple sub-cells in M time periods.

[0154] Optionally, in this example, step S302 may be replaced with: The first device determines to access one of the multiple cells to which the multiple sub-cells belong based on the first information and the current task type of the first device. Optionally, in this example, the number of sub-cells belonging to the same network device among the multiple sub-cells is the same.

[0155] Combining the above four possible implementations, optionally, the first information may be generated by the second device and informed to the first device, or the first information may also be generated by the third device and informed to the first device.

[0156] Method 1. In the case where the second device generates the first device, as Figure 4As shown, before step S301, the cell access method further includes steps S303 to S304:

[0157] S303. The first device sends second information to the second device; correspondingly, the second device receives the second information from the first device.

[0158] Wherein, the second information includes communication parameters of N types of tasks in M time periods respectively, and the communication parameters are used to determine the first information.

[0159] Optionally, in step S303, multiple terminal devices may respectively send the second information to the network device to which the cell they access belongs; correspondingly, multiple network devices respectively receive the second information from the terminal devices within their coverage areas.

[0160] Exemplarily, multiple network devices include the network devices to which multiple cells respectively belong, that is, multiple network devices include the network device to which the first cell belongs, the network device to which the second cell belongs, and the second device; thus, multiple terminal devices include the terminal devices within the coverage area of the network device to which the first cell belongs, the terminal devices within the coverage area of the network device to which the second cell belongs, and the first device.

[0161] Optionally, the communication parameters of N types of tasks in M time periods for different cells are different, and therefore, the second information received by multiple network devices is different.

[0162] Optionally, the communication parameters of a certain type of task in a certain time period may include: the operation result of the task in this time period. Exemplarily, the operation result of the task includes but is not limited to: the task runs normally, the task does not run normally.

[0163] Exemplarily, the task runs normally means that: the task runs successfully, and during the running process of this type of task, the network is smooth and there is no at least one of the phenomena of carding and delay. The task does not run normally means that: the task runs failed; or, the task runs successfully, but during the running process of this type of task, there is at least one of the phenomena of network carding, delay, and frame loss.

[0164] Optionally, for the situation where the operation result of the task includes that the task does not run normally, the communication parameters may further include the reason why the task does not run normally. For example, the task runs failed, or, during the running process of this type of task, there is at least one of the situations of network carding, delay, and frame loss.

[0165] Optionally, for the tasks that can run normally, multiple terminal devices (including but not limited to the first device) may periodically report the communication parameters corresponding to this type of task.

[0166] S304. The second device generates the first information.

[0167] Optionally, the second device may generate first information based on second information received by multiple network devices respectively from terminal devices within their coverage areas.

[0168] Optionally, after multiple network devices respectively receive the second information, they may send the second information to the second device, enabling the second device to converge the multiple second information. Further, the first information may be determined based on the multiple second information.

[0169] As a first example, the first information includes multiple cell information, and the communication quality of N types of tasks corresponding to each of the multiple cells respectively within M time periods.

[0170] Exemplarily, the second device may construct a first task map based on the multiple second information, where the first task map includes multiple cell information, and the communication quality of N types of tasks corresponding to each of the multiple cells respectively within M time periods. That is to say, the first information includes the first task map.

[0171] Optionally, the second device may, based on the time period and task type, classify the communication parameters of the same type of tasks corresponding to multiple cells within the same time period among the multiple second information into the same category, so as to determine the communication quality of the same type of tasks corresponding to multiple cells within the same time period based on the same category of communication parameters. Further, the communication quality of N types of tasks corresponding to multiple cells respectively within M time periods is determined.

[0172] Exemplarily, taking the communication parameters of task #n in time period #m corresponding to each of multiple cells as an example, the multiple cells include three cells (such as cell #1, cell #2, and cell #3), task #n is any one of the N types of tasks (i.e., a positive integer where n is less than or equal to N), and time period #m is any one of the M time periods (i.e., a positive integer where m is less than or equal to M). Among them, the communication parameters of task #n in time period #m corresponding to cell #1 include that the task runs normally; the communication parameters of task #n in time period #m corresponding to cell #2 include that the task does not run normally and there is network latency during the task running; the communication parameters of task #n in time period #m corresponding to cell #3 include that the task does not run normally and the task runs failed. Therefore, among these three cells, the running situation of task #n in time period #m corresponding to cell #1 is the best, that is to say, the communication quality of task #n in time period #m corresponding to cell #1 is the best; the running situation of task #n in time period #m corresponding to cell #2 is in the middle, that is to say, the communication quality of task #n in time period #m corresponding to cell #2 is in the middle; the running situation of task #n in time period #m corresponding to cell #3 is the worst, that is to say, the communication quality of task #n in time period #m corresponding to cell #3 is the worst.

[0173] Optionally, the communication quality of the same type of tasks corresponding to multiple cells within the same time period can be represented by different levels. That is to say, the communication quality of the same type of tasks corresponding to multiple cells within the same time period can be divided into multiple levels, so as to represent the communication quality of the same type of tasks corresponding to multiple cells within the same time period through multiple levels.

[0174] Exemplarily, taking the communication quality of task #n corresponding to cell #1 being the best within time period #m, the communication quality of task #n corresponding to cell #2 being medium within time period #m, and the communication quality of task #n corresponding to cell #3 being the worst within time period #m as an example, these 3 communication qualities can be divided into 3 levels. Therefore, the communication quality of task #n corresponding to cell #1 within time period #m can be level #1, the communication quality of task #n corresponding to cell #2 within time period #m can be level #2, and the communication quality of task #n corresponding to cell #3 within time period #m can be level #3.

[0175] It can be understood that the above only takes the example of dividing the communication quality into 3 levels for introduction. In fact, the communication quality can also be divided into multiple levels other than 3. The implementation is similar to that of the above 3 levels, as long as it is ensured that the number of levels is less than or equal to the number of communication qualities of the same type of tasks within the same time period, which will not be elaborated here.

[0176] It can be understood that the above only takes the example of introducing the implementation of the communication quality of task #n corresponding to each of the 3 cells within time period #m. The implementation of the communication quality of the remaining tasks (i.e., the tasks other than task #n in the N types of tasks) corresponding to each of the 3 cells within the remaining time periods (i.e., the time periods other than time period #m in the M time periods) is similar to the implementation of the communication quality of task #n corresponding to each of the 3 cells within time period #m. Specifically, it can refer to the relevant description of the communication quality of task #n corresponding to each of the multiple cells within time period #m above, which will not be elaborated here.

[0177] It can be understood that the above only takes the example of multiple cells including 3 cells for introduction. In fact, for other numbers of cells included in multiple cells other than 3 cells, the implementation is similar to that of the above 3 cells. Specifically, it can refer to the relevant description of the above 3 cells, which will not be elaborated here.

[0178] Based on this example, in the embodiments of the present application, the second device may determine the first information based on the communication parameters of the N types of tasks indicated by the second information in M time periods; since the first information includes multiple cell information and the communication quality of the N types of tasks corresponding to each cell in multiple cells in M time periods respectively, the first device can directly select the cell to access from the first information, which can reduce the delay of cell access and improve the efficiency of cell access.

[0179] As a second example, the first information includes the communication quality of some of the N types of tasks corresponding to multiple cells in M time periods respectively, and the relationship between the communication quality of some of the N types of tasks corresponding to multiple cells in M time periods respectively and the communication quality of the remaining N types of tasks corresponding to multiple cells in M time periods respectively. That is to say, the first information includes the information of the i-th cell, the communication quality of some of the N types of tasks corresponding to the i-th cell in M time periods respectively, and the relationship between the communication quality of some of the N types of tasks corresponding to the i-th cell in M time periods respectively and the communication quality of the remaining N types of tasks corresponding to the i-th cell in M time periods respectively.

[0180] Exemplarily, taking some tasks including task #1 and the remaining tasks including task #2 as an example, in any one of the M time periods, there is a functional relationship between the communication quality of task #1 of the i-th cell and the communication quality of task #2 of the i-th cell. For example, the communication quality of task #1 of the i-th cell and the communication quality of task #2 of the i-th cell may satisfy the following relationship (1):

[0181] The communication quality of task #2 of the i-th cell = f(The communication quality of task #1 of the i-th cell) Relationship (1)

[0182] Exemplarily, in this example, the parameters included in the first information are: the communication quality (i.e., the communication quality of some tasks corresponding to each other in M time periods respectively) and the relationship between the communication quality of some tasks and the communication quality of the remaining tasks (i.e., the relationship between the communication quality of some tasks corresponding to each other in M time periods respectively and the communication quality of the remaining tasks corresponding to each other in M time periods respectively).

[0183] Specifically, taking the example that some tasks in the N types of tasks include Task #1 and the remaining tasks in the N types of tasks include Task #2, the first information may include the communication quality of Task #1 corresponding to the first cell within M time periods, the relationship between the communication quality of Task #1 corresponding to the first cell within M time periods and the communication quality of Task #2 corresponding to the first cell within M time periods, the communication quality of Task #1 corresponding to the second cell within M time periods, and the relationship between the communication quality of Task #1 corresponding to the second cell within M time periods and the communication quality of Task #2 corresponding to the second cell within M time periods. For example, for the communication quality of Task #1 and Task #2 corresponding to the first cell within M time periods respectively, it may include the content shown in Table 6 below:

[0184] Table 6

[0185] Time period #1 Time period #2 … Time period #M Task #1 Communication quality #1 Communication quality #2 … Communication quality #M Task #2 Relationship between communication qualities #1 Relationship between communication qualities #2 … Relationship between communication qualities #M

[0186] Among them, the relationship between the communication quality of Task #1 corresponding to the first cell within M time periods and the communication quality of Task #2 corresponding to the first cell within M time periods includes: the relationship #1 between the communication qualities in Table 6 above to the relationship #M between the communication qualities.

[0187] Exemplarily, the second device may construct a second task map and task relationships based on multiple second information. Among them, the second task map includes multiple cell information, and the communication quality of partial tasks corresponding to each cell among the multiple cells within M time periods respectively; the task relationships include the relationship between the communication quality of partial tasks corresponding to each cell among the multiple cells within M time periods respectively and the communication quality of the remaining tasks corresponding to each cell among the multiple cells within M time periods respectively.

[0188] Optionally, the second device may determine the communication quality of the N types of tasks corresponding to multiple cells within M time periods respectively. Further, determine the relationship between the communication quality of partial tasks and the communication quality of the remaining tasks, so as to generate the first information.

[0189] Exemplarily, the implementation of the communication quality of the N types of tasks corresponding to multiple cells within M time periods respectively is the same as the implementation of the communication quality of the N types of tasks corresponding to multiple cells within M time periods in the above first example. Specifically, reference may be made to the relevant description of the above first example and will not be elaborated here.

[0190] Optionally, there is a strong correlation between partial tasks and the remaining tasks. That is, the correlation between partial tasks and the remaining tasks is greater than the first threshold. Exemplarily, the first threshold may be 95%. Or, the first threshold may also be other values, without limitation.

[0191] Optionally, the second device may determine the relationship between the communication quality of the partial tasks and the communication quality of the remaining tasks for each of the multiple cells based on the communication quality of the partial tasks for each of the multiple cells in M time periods and the communication quality of the remaining tasks for each of the multiple cells in M time periods.

[0192] Optionally, for the communication quality of N types of tasks for each of the multiple cells in M time periods, after the first device receives the first information, it may determine the communication quality of the remaining tasks for each of the M time periods based on the communication quality of the partial tasks for each of the M time periods and the relationship between the communication quality of the partial tasks and the communication quality of the remaining tasks; thereby, it may determine whether to access the first cell or the second cell.

[0193] Based on this example, the second device may determine the first information based on the communication parameters of N types of tasks for each of the M time periods indicated by the second information; wherein, the first information includes the communication quality of the partial tasks of N types of tasks for each of the multiple cells in M time periods and the relationship between the communication quality of the partial tasks and the communication quality of the remaining tasks for each of the multiple cells in M time periods. Compared with the solution where the second device directly sends the communication quality of N types of tasks for each of the multiple cells in M time periods to the first device, the relationship between the communication quality of the partial tasks and the communication quality of the remaining tasks occupies less resources, thereby saving communication and storage overhead.

[0194] Based on the above method 1, in the embodiments of the present application, the second device may determine the first information based on the communication parameters of N types of tasks for each of the M time periods indicated by the second information; which provides a basic guarantee for the first device to determine the access cell based on the first information.

[0195] Method 2, when the second device generates a third device, as Figure 5 shown, before step S301, the cell access method further includes steps S305 to S308:

[0196] S305. Step S305 is the same as the above step S303, and specifically, reference may be made to the relevant description of the above step S303, which will not be elaborated here.

[0197] S306. Multiple network devices respectively send the second information to the third device, and correspondingly, the third device receives the second information from the multiple network devices.

[0198] S307. The third device generates the first information.

[0199] Exemplarily, the implementation of the third device generating the first information is similar to the implementation of the second device generating the first information in the above step S304, and specifically, reference may be made to the relevant description of the above step S304, which will not be elaborated here.

[0200] S308. The third device sends the first information to the second device. Correspondingly, the second device receives the first information from the third device.

[0201] Based on the above-mentioned second method, in the embodiments of the present application, the third device may determine the first information based on the communication parameters of the N types of tasks indicated by the second information in M time periods respectively; Exemplarily, the third device may be a cloud. Since the cloud has a larger computing power compared to a base station, therefore, based on the first information determined by the third device, the accuracy is higher and the operation delay is lower, thereby improving the efficiency of cell access.

[0202] In addition to the first information described in the above embodiments, the first information may also include the following two possible implementation forms:

[0203] In the first possible implementation form, the first information is used to indicate multiple cell information and the communication quality of N types of tasks corresponding to multiple cells, where the multiple cells include a first cell and a second cell. That is to say, the first information can be used to indicate the first cell information and the communication quality of N types of tasks corresponding to the first cell, and to indicate the second cell information and the communication quality of N types of tasks corresponding to the second cell.

[0204] Exemplarily, the communication quality of the N types of tasks corresponding to the i-th cell can be understood as: the communication quality of each type of task in the N types of tasks of the i-th cell. i = 1, 2,..., X, where X is the number of cells of the multiple cells.

[0205] Optionally, the communication quality of the N types of tasks corresponding to the i-th cell indicated by the first information can be understood as: for each cell, each task in the N types of tasks corresponds to a communication quality respectively; that is to say, the communication quality corresponding to the i-th cell includes N communication qualities. Among them, the communication quality corresponding to the i-th cell can be understood as: among the communication qualities indicated by the first information, the communication quality related to the i-th cell; that is, the communication quality of the N types of tasks corresponding to the i-th cell.

[0206] Exemplarily, under this optional solution, the first information may include the content shown in Table 3 above. For details, please refer to the relevant description of Table 3 above, and will not be elaborated here.

[0207] Exemplarily, in this possible implementation form, the first device may determine to access the first cell or the second cell based on the above-mentioned step S302. For details, please refer to the relevant description of the above-mentioned step S302, and will not be elaborated here.

[0208] Optionally, the first information may be generated by the second device and notified to the first device, or the first information may also be generated by the third device and notified to the first device. Exemplarily, the implementation manner of the first information is similar to that of the first information in the above embodiment, and the specific description of the first information in the above embodiment may be referred to, which will not be elaborated here.

[0209] Based on the above possible implementation manners, the first information is used to indicate the information of multiple cells and the communication quality of N types of tasks corresponding to multiple cells. Therefore, the first device can select the accessed cell based on its task type, so as to provide differentiated assistance for different tasks, thereby improving the optimization degree of cell selection and enhancing the user experience.

[0210] In the second possible implementation form, the first information is used to indicate the information of multiple cells and the communication quality of the corresponding multiple cells in M time periods respectively, where the multiple cells include the first cell and the second cell. That is to say, the first information is used to indicate the first cell information and the communication quality of the corresponding first cell in M time periods, and to indicate the second cell information and the communication quality of the corresponding second cell in M time periods.

[0211] Exemplarily, the communication quality of the i-th cell in M time periods can be understood as: the communication quality of the i-th cell in each of the M time periods. i = 1, 2,..., X, where X is the number of cells of the multiple cells.

[0212] Optionally, the communication quality of the corresponding i-th cell indicated by the first information in M time periods respectively can be understood as: for each cell, each of the M time periods corresponds to a communication quality; that is to say, the communication quality corresponding to the i-th cell includes M communication qualities. Among them, the communication quality corresponding to the i-th cell can be understood as: among the communication qualities indicated by the first information, the communication quality related to the i-th cell; that is, the communication quality of the corresponding i-th cell in M time periods respectively.

[0213] Exemplarily, under this optional solution, the first information may include the content shown in Table 2 above. The specific description of Table 2 above may be referred to, which will not be elaborated here.

[0214] Optionally, in this possible implementation form, step S302 may be replaced by: the first device determines to access the first cell or the second cell based on the first information and the time period to which the current moment belongs in the M time periods.

[0215] Exemplarily, since the first device can select one of the communication qualities in the communication qualities of the time period to which the current moment belongs in the M time periods indicated by the first information based on the current moment, and determine to access the cell corresponding to the communication quality. For example, the communication quality may be the best communication quality in the communication qualities of the time period to which the current moment belongs.

[0216] Exemplarily, under this optional solution, the implementation of the first device determining to access the first cell or the second cell is similar to the implementation of the first device determining to access the first cell or the second cell in step S302 above. Specifically, reference may be made to the relevant description of step S302 above, which will not be elaborated herein.

[0217] Optionally, the first information may be generated by the second device and notified to the first device, or the first information may also be generated by the third device and notified to the first device. Exemplarily, the implementation manner of the first information is similar to the implementation of the first information in the above embodiments. Specifically, reference may be made to the relevant description of the first information in the above embodiments, which will not be elaborated herein.

[0218] Based on the above possible implementation manners, the first information is used to indicate multiple cell information and the communication quality of the corresponding multiple cells in M time periods respectively. Therefore, the first device can select the accessed cell based on its task type, so as to provide differential assistance for different tasks, thereby improving the optimization degree of cell selection and enhancing the user experience.

[0244] Wherein, all relevant contents of each step involved in the above method embodiments can be cited in the function descriptions of the corresponding functional modules, and will not be elaborated here.

[0245] In the present application, the communication device 700 may be presented in a form of integrating and dividing each functional module. Here, a "module" may refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and a memory that execute one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0246] In some embodiments, when Figure 7When the communication device 700 in [ID] is a chip or a chip system, the functions / implementation processes of the transceiver module 702 can be implemented through the input / output interface (or communication interface) of the chip or chip system, and the functions / implementation processes of the processing module 701 can be implemented through the processor (or processing circuit) of the chip or chip system.

[0247] Since the communication device 700 provided in this embodiment can execute the above method, the technical effects it can obtain can refer to the above method embodiments and will not be elaborated here.

[0248] As a possible product form, any one of the first device, the second device, or the third device described in the embodiments of the present application can also be implemented using the following: one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gate logic, discrete hardware components, any other suitable circuits, or any combination of circuits capable of performing various functions described throughout the present application.

[0249] As another possible product form, any one of the first device, the second device, or the third device described in the embodiments of the present application can be implemented by a general bus architecture. For ease of explanation, see Figure 8 , Figure 8 is a schematic structural diagram of a communication device 800 provided in an embodiment of the present application. The communication device 800 includes a processor 801 and a transceiver 802. The communication device 800 can be the first device, or a chip or chip system therein; or, the communication device 800 can be the second device, or a chip or module therein; or, the communication device 800 can be the third device, or a chip or module therein. Figure 8 Only the main components of the communication device 800 are shown. In addition to the processor 801 and the transceiver 802, the communication device may further include a memory 803 and an input / output device (not shown in the figure).

[0250] Optionally, the processor 801 is mainly used to process communication protocols and communication data, control the entire communication device, execute software programs, and process data of software programs. The memory 803 is mainly used to store software programs and data. The transceiver 802 may include a radio frequency circuit and an antenna. The radio frequency circuit is mainly used for the conversion between baseband signals and radio frequency signals and the processing of radio frequency signals. The antenna is mainly used to receive and transmit radio frequency signals in the form of electromagnetic waves. Input / output devices, such as touch screens, displays, keyboards, etc., are mainly used to receive data input by users and output data to users.

[0251] Optionally, the processor 801, the transceiver 802, and the memory 803 may be connected through a communication bus.

[0252] After the communication device is powered on, the processor 801 may read the software program in the memory 803, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be wirelessly transmitted, after the processor 801 performs baseband processing on the data to be transmitted, it outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 801. The processor 801 converts the baseband signal into data and processes the data.

[0253] In another implementation, the radio frequency circuit and the antenna may be provided independently of the processor performing baseband processing. For example, in a distributed scenario, the radio frequency circuit and the antenna may be independent of the communication device and arranged in a remote manner.

[0254] In some embodiments, in terms of hardware implementation, those skilled in the art can conceive that the above communication device 700 may adopt Figure 8 the form of the communication device 800 shown.

[0255] As an example, Figure 7 the function / implementation process of the processing module 701 in Figure 8 can be implemented by the processor 801 in the communication device 800 shown calling the computer-executable instructions stored in the memory 803. Figure 7 the function / implementation process of the transceiver module 702 in Figure 8 can be implemented by the transceiver 802 in the communication device 800 shown.

[0256] As another possible product form, any one of the first device, the second device, or the third device in the present application may adopt Figure 9 the composition structure shown, or include Figure 9 the components shown. Figure 9 FIG. 31 is a schematic diagram of the composition of a communication device 900 provided by the present application. The communication device 900 may be a terminal device, or a chip or system-on-chip in a terminal device; or, it may be a module, a chip, or a system-on-chip in any one of the first device, the second device, or the third device.

[0257] As Figure 9 shown, the communication device 900 includes at least one processor 901 and at least one communication interface ( Figure 9is only exemplary and is described by taking a communication interface 904 and a processor 901 as an example. Optionally, the communication device 900 may further include a communication bus 902 and a memory 903.
