Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a communication method, a communication system, a communication device and a computer-readable storage medium. Background Art

[0002] With the development and popularization of communication technology, the frequency bands used in wireless communication are getting higher and higher, and the coverage area will become smaller accordingly, and the number of users in the cell will also decrease accordingly. However, the users in the cell have higher requirements for data traffic. In order to meet the network usage needs of users with large traffic, many areas have multiple cell coverage. For user equipment, in order to ensure the quality of network communication, it is usually necessary to switch between multiple cells.

[0003] However, the inventor of the present invention has found that although the speed of cell switching of user equipment in the prior art is relatively fast, seamless switching cannot be achieved, resulting in that the network services of the user equipment are affected. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a communication method, a communication system, a communication device and a computer-readable storage medium, which can effectively reduce the switching of user equipment between different cells while ensuring the network usage requirements of user equipment.

[0005] To solve the above technical problems, an embodiment of the present invention provides a communication method, comprising the following steps: forming a secondary cell that is communication-connected to a primary cell, wherein the number of channels used to transmit system information in the secondary cell is less than a preset threshold; obtaining a target user device that meets preset conditions from user devices accessing the primary cell; and establishing a communication connection between the target user device and the secondary cell.

[0006] An embodiment of the present invention further provides a communication system, comprising a primary cell and a secondary cell in communication connection, wherein the number of channels used to transmit system information in the secondary cell is less than a preset threshold; the primary cell and the secondary cell are used to execute the communication method as described above.

[0007] An embodiment of the present invention also provides a communication device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the communication method as described above.

[0008] An embodiment of the present invention further provides a computer-readable storage medium storing a computer program, wherein the computer program implements the aforementioned communication method when executed by a processor.

[0009] Compared with the prior art, the implementation method of the present invention forms a secondary cell that is in communication connection with the primary cell, and for the target user equipment that meets the preset conditions in the primary cell, an additional communication connection is established between the target user equipment and the secondary cell, thereby meeting the network usage requirements of the target user equipment; since the number of channels used to transmit system information in the secondary cell is less than the preset threshold, the user equipment establishes a communication connection with the secondary cell, and the secondary cell sends less system information to the user equipment, so that the user equipment will not identify the secondary cell as an independent cell, and will not switch between cells, thereby effectively reducing the switching of the user equipment between different cells. In addition, since the number of channels used to transmit system information in the secondary cell is less than the preset threshold, the channels originally used to transmit system information in the secondary cell can be used to transmit the network services of the target user equipment, effectively improving the data transmission capacity of the secondary cell; at the same time, when transmitting the same network traffic, the secondary cell sends less system information to the user equipment, which can effectively reduce the power consumption of the entire communication system.

[0021] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0022] The first embodiment of the present invention relates to a communication method, the specific steps are as follows: Figure 1 As shown, including:

[0023] Step S101: forming a secondary cell in communication connection with a primary cell.

[0024] Specifically, in this step, the secondary cell is a special communication cell, and the number of channels used to transmit system information in the secondary cell is less than the preset threshold. Since the number of channels used to transmit system information in the secondary cell is small, the secondary cell cannot send a sufficient amount of system information such as broadcast, access, and control to the user equipment. Therefore, the user equipment will not regard the secondary cell as an independent communication cell, and the secondary cell will not directly access the user equipment. Among them, the preset threshold can be flexibly set according to actual needs. In actual application, the smaller the preset threshold, the fewer the number of channels that can be used to transmit system information in the secondary cell. Since the number of channels used to transmit system information in the secondary cell is less than the preset threshold, the channels originally used to transmit system information in the secondary cell can be used to transmit network services of the target user equipment, which effectively improves the data transmission capacity of the secondary cell; at the same time, when transmitting the same network traffic, the secondary cell sends less system information to the user equipment, which can effectively reduce the power consumption of the entire communication system.

[0025] Step S102: Acquire target user equipment that meets a preset condition from user equipments accessing the primary cell.

[0026] Specifically, in this step, the target user equipment is obtained, that is, the user equipment with a priority higher than the preset priority or a data flow greater than the preset flow value is obtained. The level of the priority and the size of the data flow can reflect the size of the user equipment's demand for network flow. Using the priority and data flow to obtain the target user equipment can effectively ensure that the user equipment with a large demand for network flow is obtained.

[0027] It can be understood that the above-mentioned acquisition of user equipment with a priority higher than the preset priority or a data traffic greater than the preset traffic value as the target user equipment is only a specific example in this embodiment and does not constitute a limitation. In other embodiments of the present invention, user equipment with a usage time greater than the preset time can also be used as the target user equipment, etc., which are not listed one by one here, and can be flexibly set according to actual needs.

[0028] Step S103: Establish a communication connection between the target user equipment and the secondary cell.

[0029] Specifically, in this implementation, after the target user equipment establishes a communication connection with the secondary cell, the secondary cell will provide network business services to the user terminal in the form of a secondary carrier. It can be understood that the secondary cell providing network business services to the user terminal in the form of a secondary carrier is only a specific example in this implementation and does not constitute a limitation. In actual application, the secondary cell may also provide network business services to the user terminal in other forms such as dual links, which can be flexibly set according to actual needs.

[0030] Furthermore, in this embodiment, in order for the user terminal to connect to the primary cell and the secondary cell simultaneously, the coverage area of ​​the primary cell and the coverage area of ​​the secondary cell should at least partially overlap, thereby ensuring that after the target user equipment is selected, the target user equipment can establish a communication connection with the secondary cell.

[0031] Compared with the prior art, in the communication method provided by the first embodiment of the present invention, by forming a secondary cell that is in communication connection with the primary cell, for a target user device that meets the preset conditions and has a large network traffic demand in the primary cell, an additional communication connection between the target user device and the secondary cell is established, and the secondary cell provides network business services to the user terminal in the form of a secondary carrier, thereby meeting the network usage requirements of the target user device with large demand. Since the number of channels used to transmit system information in the secondary cell is less than the preset threshold, even if the user equipment establishes a communication connection with the secondary cell, the secondary cell sends less system information to the user equipment, so that the user equipment will not identify the secondary cell as an independent cell, and will not switch between cells, thereby effectively reducing the switching of user equipment between different cells.

[0032] It should be noted that, in this implementation, the secondary cell may be a new cell established according to preset parameters, or an existing primary cell may be converted into a secondary cell by adjusting relevant parameters of the existing primary cell.

[0033] In a specific solution that can be implemented, the specific steps of establishing a new cell as a secondary cell can be as follows: Figure 2 As shown, including:

[0034] Step S201: configuring cell-related parameters in the background network management according to preset parameters.

[0035] Step S202: The cell control module reads relevant parameters of the background configuration.

[0036] Step S203: Check whether the relevant parameters configured in the background meet the invisible cell parameter conditions. If so, execute steps S204 and S205; if not, execute step S206.

[0037] Step S204: Perform necessary channel parameter configuration on each module.

[0038] Step S205: Determine whether to send broadcast information to adjacent cells according to parameter configuration.

[0039] Specifically, in this step, some channels used to send system information, such as control channels, random access channels, etc., can be configured less or not configured. For MIB (Management Information Base) and SIBs (Super Information Base), it can be decided whether to send them according to actual needs. In addition, when sending a super information base, the cycle of the super information base can be configured longer. With this setting, some channels used to transmit system information can be used to transmit network service data, saving time and frequency resources originally used to transmit system information. At the same time, the resource blocks used for scheduling network service data will be larger and less avoidance will be reduced, which is more conducive to the scheduling of large data flows.

[0040] Step S206: Generate an invalid parameter alarm or event.

[0041] In another specific solution that can be implemented, the step of converting an existing primary cell into a secondary cell can be as follows: Figure 3 As shown, including:

[0042] Step S301: Acquire a second primary cell that is in communication connection with the primary cell.

[0043] Step S302: when the number of users in the second primary cell is less than a preset threshold, user equipment in the second primary cell is moved out of the second primary cell.

[0044] Step S303: Change relevant parameters of the second primary cell to form a secondary cell.

[0045] Specifically, in this step, the relevant parameters of the second primary cell are changed mainly to reduce the relevant channels used for transmitting system parameters in the second primary cell, so as to convert the second primary cell into a secondary cell.

[0046] By modifying relevant parameters of the second primary cell, the second primary cell is converted into a secondary cell, thereby eliminating the need to build a new cell as a secondary cell, effectively utilizing existing resources and reducing the construction cost of the secondary cell.

[0047] Preferably, in this embodiment, changing the relevant parameters of the second primary cell includes an automatic mode and a manual mode. In the automatic mode, the values ​​of the relevant parameters to be modified are pre-set. When the second primary cell needs to be converted to a secondary cell, a pre-set program is executed to modify the relevant parameters to the preset values, thereby completing the conversion of the primary cell to the secondary cell. In the manual mode, when the second primary cell needs to be converted to a secondary cell, the second primary cell generates an alarm or notification event to inform the administrator to make manual modifications, thereby completing the conversion of the primary cell to the secondary cell.

[0048] It is understandable that the above is only a specific example of forming a secondary cell in communication connection with the primary cell in this embodiment, and does not constitute a limitation. In actual application, some steps may be added, reduced or changed, which are not listed here one by one.

[0049] The second embodiment of the present invention relates to a communication method. The communication method provided by the second embodiment is substantially the same as the communication method provided by the first embodiment. The difference is that the second embodiment, based on the first embodiment, further includes the step of determining a target secondary cell from a plurality of secondary cells that are in communication connection with the primary cell according to the target user equipment. The specific steps are as follows: Figure 4 As shown, including:

[0050] Step S401: forming a secondary cell in communication connection with a primary cell.

[0051] Step S402: acquiring target user equipment that meets a preset condition from user equipments accessing the primary cell.

[0052] It should be noted that, since step S401 and step S402 in this embodiment are substantially the same as step S101 and step S102 in the first embodiment, the specific details may be referred to the specific description in the first embodiment, which will not be repeated here.

[0053] Step S403: According to the target user equipment, a target secondary cell is determined from a plurality of secondary cells in communication connection with the primary cell.

[0054] Specifically, in this step, after the target user equipment is obtained, the most suitable secondary cell is selected from multiple secondary cells as the target secondary cell according to the priority and / or data flow of the target user equipment. Among them, the priority of the target secondary cell must be greater than the priority of the target user equipment, and the network service capacity must be greater than the data flow of the target user equipment, so as to ensure that the secondary cell can meet the network service requirements of the target user equipment. It can be understood that selecting the target secondary cell according to the priority and / or data flow of the target user equipment is only a specific example in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the target secondary cell can also be selected according to the usage time of the target user equipment, etc., which are not listed one by one here, and can be flexibly set according to actual needs.

[0055] Step S404: Establish a communication connection between the target user equipment and the target secondary cell.

[0056] It should be noted that, since step S404 in this embodiment is substantially the same as step S103 in the first embodiment, specific details may be referred to the specific description in the first embodiment, which will not be repeated here.

[0057] Compared with the prior art, the communication method provided in the second embodiment of the present invention is improved on the basis of the first embodiment. While retaining all the technical effects of the first embodiment, the corresponding target secondary cell is selected according to the target user equipment, so that the main cell and the secondary cell provide network services to the target user equipment at the same time, thereby ensuring that the target secondary cell can meet the network service requirements of the target user equipment.

[0058] The third embodiment of the present invention relates to a communication method. The communication method provided by the third embodiment is substantially the same as the communication method provided by the first embodiment. The difference is that the third embodiment, based on the first embodiment, further includes the step of periodically detecting the working status of each secondary cell and sending the detection result to the primary cell. The specific steps are as follows: Figure 5 As shown, including:

[0059] Step S501: forming a secondary cell in communication connection with a primary cell.

[0060] Step S502: acquiring target user equipment that meets a preset condition from user equipments accessing the primary cell.

[0061] Step S503: Establish a communication connection between the target user equipment and the secondary cell.

[0062] It should be noted that, since steps S501 to S503 in this embodiment are substantially the same as steps S101 to S103 in the first embodiment, specific details may be referred to the specific description in the first embodiment, which will not be repeated here.

[0063] Step S504: regularly detect the working status of each secondary cell and send the detection result to the primary cell.

[0064] Specifically, in this step, the detection interval duration can be set by a detection timer, and the working status of each secondary cell can be detected at intervals, such as detecting whether an abnormality occurs in the secondary cell and / or whether there are resources in the secondary cell that reach a preset critical value, and broadcasting the detection results to the adjacent primary cell.

[0065] Compared with the prior art, the communication method provided in the third embodiment of the present invention is improved on the basis of the first embodiment. While retaining all the technical effects of the first embodiment, the working status of the secondary cell is regularly detected, and the detection results are broadcast to the adjacent main cell, so that the main cell is more aware of the working status of the secondary cell, avoiding the main cell from allocating user equipment to the secondary cell where an abnormality occurs, or allocating user equipment that exceeds the working capacity of the secondary cell, resulting in the network traffic demand of the user equipment cannot be met, thereby ensuring that the secondary cell can meet the network traffic demand of the user equipment.

[0066] The fourth embodiment of the present invention relates to a communication method. The communication method provided by the fourth embodiment is substantially the same as the communication method provided by the first embodiment. The difference is that the fourth embodiment, based on the first embodiment, further includes the step of converting a secondary cell connected to the overloaded primary cell into a primary cell when the primary cell is overloaded. The specific steps are as follows: Figure 6 As shown, including:

[0067] Step S601: forming a secondary cell in communication connection with a primary cell.

[0068] Step S602: Acquire target user equipment that meets a preset condition from user equipments accessing the primary cell.

[0069] Step S603: Establish a communication connection between the target user equipment and the secondary cell.

[0070] It should be noted that, since steps S601 to S603 in this embodiment are substantially the same as steps S101 to S103 in the first embodiment, specific details may be referred to the specific description in the first embodiment, which will not be repeated here.

[0071] Step S604: when the primary cell is overloaded, the secondary cell in communication connection with the overloaded primary cell is converted into the primary cell.

[0072] Specifically, in this step, when it is detected that the number of users accessed by the primary cell is greater than the maximum number of users it can accommodate, the primary cell is considered to be overloaded. In order to avoid the degradation of network service quality or damage to the primary cell caused by the overload of the primary cell, at least one secondary cell connected to the overloaded primary cell is converted to the primary cell. Some of the overloaded users are connected to the new primary cell. By converting the secondary cell to the primary cell, the network capacity of the entire communication system is improved.

[0073] Furthermore, in this step, the specific steps of converting the secondary cell into the primary cell are as follows: Figure 7 As shown, including:

[0074] Step S701: upon receiving an overload notification message sent by the primary cell, determine whether the secondary cell is in manual mode, if so, execute step S702, if not, execute step S703.

[0075] Step S702: Generate an alarm or event and notify the administrator for processing.

[0076] Step S703: disconnect the secondary cell from the user equipment.

[0077] Specifically, in this implementation, the secondary cell is connected to the user equipment in the form of a secondary carrier. Therefore, when the secondary cell is disconnected from the user equipment, the secondary cell notifies all adjacent primary cells to release the secondary carrier of the secondary cell and no longer accepts secondary carrier requests.

[0078] Step S704: Re-establish the cell according to the primary cell parameters and send a broadcast.

[0079] Specifically, in this step, after receiving the secondary carrier release message fed back by the primary cell, the parameters of the current secondary cell are modified and configured according to the parameters of the primary cell, thereby converting the secondary cell into the primary cell.

[0080] Compared with the prior art, the communication method provided in the fourth embodiment of the present invention is improved on the basis of the first embodiment. While retaining all the technical effects of the first embodiment, when the number of users in the main cell is overloaded, the secondary cell connected to the overloaded main cell is converted into a new main cell, so that some user equipment can be connected to the new main cell, effectively improving the network capacity of the communication system.

[0081] The fifth embodiment of the present invention relates to a communication method. The communication method provided in the fifth embodiment is substantially the same as the communication method provided in the first embodiment. The difference is that the fifth embodiment, based on the first embodiment, further includes a step of disconnecting the communication connection between the target user equipment and the secondary cell when it is detected that the target user equipment does not meet the preset condition. The specific steps are as follows: Figure 8 As shown, including:

[0082] Step S801: forming a secondary cell in communication connection with a primary cell.

[0083] Step S802: Acquire target user equipment that meets a preset condition from user equipments accessing the primary cell.

[0084] Step S803: Establish a communication connection between the target user equipment and the secondary cell.

[0085] It should be noted that, since steps S801 to S803 in this embodiment are substantially the same as steps S101 to S103 in the first embodiment, specific details may be referred to the specific description in the first embodiment, which will not be repeated here.

[0086] Step S804: when it is detected that the target user equipment does not meet the preset condition, the communication connection between the target user equipment and the secondary cell is disconnected.

[0087] Specifically, in this step, after the target user equipment accesses the secondary cell, the target user equipment accessing the secondary cell is regularly detected to determine whether it still meets the preset conditions. If the target user equipment no longer meets the preset conditions is detected, its communication connection with the secondary cell is disconnected.

[0088] Compared with the prior art, the communication method provided in the fifth embodiment of the present invention is improved on the basis of the first embodiment. While retaining all the technical effects of the first embodiment, it regularly detects and disconnects the connection between the secondary cell and the user equipment that does not meet the preset conditions, so as to avoid the secondary cell being occupied by the user equipment that does not meet the preset conditions, so that the secondary cell can better provide network services.

[0089] The sixth embodiment of the present invention relates to a communication method, the specific steps are as follows: Fig. 9 As shown, including:

[0090] Step S901: forming a secondary cell in communication connection with a primary cell.

[0091] Step S902: Acquire target user equipment that meets a preset condition from user equipments accessing the primary cell.

[0092] Step S903: Establish a communication connection between the target user equipment and the secondary cell.

[0093] It should be noted that, since steps S901 to S903 in this embodiment are substantially the same as steps S101 to S103 in the first embodiment, specific details may be referred to the specific description in the first embodiment, which will not be repeated here.

[0094] Step S904: When the user equipment detects the second primary cell, it determines whether to perform primary cell switching. If so, step S905 is executed. If not, the process ends.

[0095] Specifically, in this step, when the user detects the second primary cell, it can be determined whether the primary cell needs to be switched according to the working state and service range of the current primary cell. For example, if the current primary cell is abnormal, or it is predicted that the user equipment is about to move out of the coverage of the current primary cell, the primary cell is switched, otherwise the primary cell is not switched. It can be understood that the above is only a specific example of this implementation mode and does not constitute a limitation.

[0096] Step S905: Switch the user equipment to the second primary cell.

[0097] Step S906: Detect whether the secondary cell is compatible with the second primary cell. If so, end the process. If not, execute step S907.

[0098] Specifically, in this implementation, it can be detected whether the secondary cell currently connected by the user equipment meets the carrier requirement of the second primary cell. If so, the secondary cell currently connected by the user equipment is directly added to the admission information of the second primary cell. It can be understood that the above is only a specific example of determining whether the secondary cell and the second primary cell are compatible in this implementation. In actual application, it can also be determined according to conditions such as coverage area, which are not listed here one by one.

[0099] Step S907: disconnect the communication connection between the user equipment and the secondary cell.

[0100] Compared with the prior art, the communication method provided in the sixth embodiment of the present invention is improved on the basis of the first embodiment. While retaining all the technical effects of the first embodiment, when a second main cell is detected, if the secondary cell to which the user equipment is currently connected is adapted to the second main cell, the main cell is directly switched without disconnecting the communication connection between the user equipment and the secondary cell, thereby effectively simplifying the process of switching the main cell.

[0101] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they contain the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.

[0102] A seventh embodiment of the present invention relates to a communication system, such as Fig.10As shown, it includes: a primary cell 101 and a secondary cell 102 in communication connection, wherein the channel used for transmitting system information in the secondary cell 102 is less than a preset threshold. The primary cell 101 and the secondary cell 102 are used to execute the communication method provided by any of the above embodiments.

[0103] It can be understood that this embodiment is an embodiment of a communication system corresponding to the above method embodiment. Therefore, the communication system provided by this embodiment also has the technical effects of the above method embodiment, which will not be repeated here.

[0105] Among them, the memory 1102 and the processor 1101 are connected in a bus manner, and the bus may include any number of interconnected buses and bridges, and the bus connects various circuits of one or more processors 1101 and the memory 1102 together. The bus can also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface between the bus and the transceiver. The transceiver can be one element or multiple elements, such as multiple receivers and transmitters, providing a unit for communicating with various other devices on a transmission medium. The data processed by the processor 1101 is transmitted on a wireless medium through an antenna, and further, the antenna also receives data and transmits the data to the processor 1101.

[0106] The processor 1101 is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interfaces, voltage regulation, power management and other control functions. The memory 1102 can be used to store data used by the processor 1101 when performing operations.
