Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a RedCap intelligent measurement and switching control method, system and device. Background Art

[0002] The 3GPP R17 standard defines RedCap (Reduced Capability) technology, which is designed to carry medium- and high-speed mobile IoT services. RedCap technology has a wide range of application scenarios, covering industry applications such as video surveillance, smart power, smart manufacturing, and consumer electronics products such as wearable devices.

[0003] RedCap terminals can only reside in 5G cells that support RedCap technology (hereinafter referred to as 5G RedCap cells), but cannot reside in ordinary 5G cells that do not support RedCap technology (hereinafter referred to as 5G ordinary cells). The large-scale application of RedCap terminals depends on the large-scale coverage of the 5G RedCap network. However, the current 5G commercial network coverage breadth and depth are still insufficient, and the 5G commercial network needs to be adapted and upgraded to support the access of RedCap terminals.

[0004] In the current 5G network environment, 5G RedCap cells coexist with 5G ordinary cells, and this coexistence is expected to continue for a long time. In this hybrid network environment, how to optimize the connection state mobility management of RedCap terminals, ensure the continuity and mobility of RedCap services, and thus improve the user experience of RedCap terminals is of great significance to the large-scale development of RedCap technology.

[0005] RedCap terminals usually reside in a 5G cell that supports RedCap (service cell CELL1) and establish a service connection. During the movement of the terminal, switching or redirection operations are required. In order to improve the success rate of switching or redirection, some optimization methods are currently used on the terminal side, such as: CN117336802A-A RedCap terminal and its switching control method: When the RedCap terminal switches or redirects to any NR cell, if it is found that the NR cell does not allow the RedCap terminal to access, the cell information is added to the blacklist to prevent subsequent unnecessary attempts.

[0006] However, this approach has the following limitations:

[0007] 1. High storage capacity requirements:

[0008] As RedCap terminals continue to move, the information in the blacklist continues to increase, which places high demands on the storage capacity of the terminal. The long-term accumulation of blacklist information will take up a lot of storage space and increase the burden on terminal hardware.

[0009] 2. Risk of information loss:

[0010] When the terminal is turned off or restarted, the blacklist information may be lost. Once the information is lost, the terminal needs to relearn which cells do not support RedCap, which may lead to repeated invalid measurements and handover attempts, affecting the user experience.

[0011] 3. Information timeliness issue:

[0012] The 5G RedCap network is constantly being upgraded and improved, and the original blacklist information may become outdated. If the terminal continues to make decisions based on the old blacklist information, it may miss new cells that already support RedCap, thus affecting the success rate of handover or redirection. Summary of the invention

[0013] To solve the above problems, the present invention aims to propose a RedCap intelligent measurement and switching control method, system and device, which can reduce the invalid measurement work of the RedCap terminal through network side optimization and reduce the probability of switching or redirection failure; specifically, through the intelligent filtering mechanism on the network side, it is ensured that the terminal only measures and switches the cells that support RedCap, thereby improving business continuity and user experience.

[0014] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0015] A RedCap intelligent measurement and switching control method includes the following steps:

[0016] S1, through the intelligent filtering mechanism on the network side, real-time acquisition and maintenance of the network's neighboring area information, and collection of mobile data of multiple RedCap terminals residing on the network side;

[0017] S2. The network side sends the filtered measurement configuration information to the RedCap terminal. The measurement configuration information only contains the information of the frequency points or cells that support RedCap.

[0018] S3. After receiving the measurement configuration information, the RedCap terminal starts to measure the signal quality of the candidate target cell; after the measurement is completed, the terminal reports the measurement result to the network side;

[0019] S4. The received measurement results are filtered through the intelligent filtering mechanism on the network side. When a cell that does not support RedCap appears in the measurement results, the network side filters it out and then selects the best RedCap cell as the target cell.

[0020] S5. The network side instructs the RedCap terminal to switch to the target cell or redirect to the target cell.

[0021] Furthermore, the mobile data includes signal strength and historical switching success rate.

[0022] Furthermore, the neighboring cell information is the frequency points and cells supporting RedCap.

[0023] Furthermore, the candidate target cells are marked as CELL2, CELL3, CELL4...

[0024] Furthermore, the network side is a base station.

[0025] Furthermore, the redirection directly initiates RRC connection release to the UE through the network side, and instructs the UE to select a cell access at the frequency point where the candidate target cell is located.

[0026] In order to achieve the above object, the present invention also provides a RedCap intelligent measurement and switching control system, including the following modules:

[0027] RedCap measurement frequency and measurement cell filtering module: used to obtain and maintain the network's neighboring cell information in real time through the intelligent filtering mechanism on the network side, and collect the mobile data of multiple RedCap terminals residing under the base station;

[0028] Measurement configuration information sending module: used for the network side to send the filtered measurement configuration information to the RedCap terminal. The measurement configuration information only contains the frequency points or cells that support RedCap.

[0029] Terminal measurement and reporting module: After receiving the measurement configuration information, the RedCap terminal starts measuring the signal quality of the candidate target cell; after the measurement is completed, the terminal reports the measurement result to the network side;

[0030] Measurement result filtering and RedCap target cell selection module: used to filter the received measurement results through the intelligent filtering mechanism on the network side. When a cell that does not support RedCap appears in the measurement result, the network side filters it out and then selects the best RedCap cell as the target cell.

[0031] Switching or redirection control module: used by the network side to instruct the RedCap terminal to switch to the target cell or redirect to the target cell.

[0032] In order to achieve the above objectives, the present invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the RedCap intelligent measurement and switching control method as described above is implemented.

[0033] Beneficial effects: The present invention ensures that the RedCap terminal only measures and switches to cells that support RedCap through an intelligent filtering mechanism on the network side (initial measurement configuration information filtering + terminal reporting result filtering), thereby reducing invalid measurement workload, improving the success rate of switching or redirection, and ultimately improving the user experience of the RedCap terminal; the method of the present invention not only improves the utilization efficiency of network resources, but also enhances the adaptability and stability of the RedCap terminal in the network environment.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] Glossary:

[0040] RedCap: Reduced Capability, reduced performance

[0041] NR: New Radio

[0042] Example 1

[0043] See also Figure 1 :A RedCap intelligent measurement and switching control method, comprising the following steps:

[0044] S1, through the intelligent filtering mechanism on the network side, real-time acquisition and maintenance of the network's neighboring area information, and collection of mobile data of multiple RedCap terminals residing on the network side;

[0045] S2. The network side sends the filtered measurement configuration information to the RedCap terminal. The measurement configuration information only contains the information of the frequency points or cells that support RedCap. This ensures that the terminal only measures those candidates that may become the target cells. It ensures that the RedCap terminal only measures the cells that support RedCap, reducing the workload of invalid measurements.

[0046] S3. After receiving the measurement configuration information, the RedCap terminal starts to measure the signal quality of the candidate target cell; after the measurement is completed, the terminal reports the measurement result to the network side;

[0047] S4. The received measurement results are filtered through the intelligent filtering mechanism on the network side. When a cell that does not support RedCap appears in the measurement results, the network side filters it out and then selects the best RedCap cell as the target cell.

[0048] S5. The network side instructs the RedCap terminal to switch to the target cell or redirect to the target cell.

[0049] This embodiment ensures that the RedCap terminal only measures and switches cells that support RedCap through an intelligent filtering mechanism on the network side (initial measurement configuration information filtering + terminal reporting result filtering), thereby reducing invalid measurement workload, improving the success rate of switching or redirection, and ultimately improving the user experience of the RedCap terminal; the method of this embodiment not only improves the utilization efficiency of network resources, but also enhances the adaptability and stability of the RedCap terminal in the network environment.

[0050] In a specific example, the mobility data includes signal strength (RSRP, RSRQ) and historical handover success rate.

[0051] Based on the above historical data, the intelligent filtering mechanism of this embodiment can accurately identify the frequencies and cells that do not support RedCap; therefore, when the network side detects that the RedCap terminal needs to be switched or redirected, it will first start the intelligent filtering mechanism to filter all possible target frequencies and cells, and remove those frequencies or cells that do not support RedCap, thereby avoiding the terminal from performing unnecessary measurements on these inappropriate cells.

[0052] In a specific example, the neighboring cell information is the frequency points and cells supporting RedCap.

[0053] In this embodiment, before sending the measurement configuration information, the network side intelligently filters the candidate frequency points and cells to exclude the frequency points and cells that do not support RedCap, so as to ensure that the terminal only receives the measurement configuration information that supports RedCap.

[0054] In a specific example, the candidate target cells are marked as CELL2, CELL3, CELL4, . . .

[0055] In a specific example, the network side is a base station.

[0056] The intelligent filtering mechanism on the network side (base station) of this embodiment can be updated in real time. Even if the 5G RedCap network is continuously upgraded and improved, the terminal can still accurately identify cells that support RedCap, thereby improving the timeliness of information.

[0057] In a specific example, the redirection directly initiates RRC connection release to the UE through the network side, and instructs the UE to select a cell access at the frequency point where the candidate target cell is located.

[0058] This embodiment enhances the adaptability and stability of the RedCap terminal in the network environment through optimization control on the network side, and ensures the service continuity of the terminal during movement.

[0059] Example 2

[0060] To achieve the above purpose, see Figure 2 :This embodiment also provides a RedCap intelligent measurement and switching control system, including the following modules:

[0061] RedCap measurement frequency and measurement cell filtering module: used to obtain and maintain the network's neighboring cell information in real time through the intelligent filtering mechanism on the network side, and collect the mobile data of multiple RedCap terminals residing under the base station;

[0062] Measurement configuration information sending module: used for the network side to send the filtered measurement configuration information to the RedCap terminal. The measurement configuration information only contains the frequency points or cells that support RedCap.

[0063] Terminal measurement and reporting module: After receiving the measurement configuration information, the RedCap terminal starts measuring the signal quality of the candidate target cell; after the measurement is completed, the terminal reports the measurement result to the network side;

[0064] Measurement result filtering and RedCap target cell selection module: used to filter the received measurement results through the intelligent filtering mechanism on the network side. When a cell that does not support RedCap appears in the measurement result, the network side filters it out and then selects the best RedCap cell as the target cell.

[0065] Switching or redirection control module: used by the network side to instruct the RedCap terminal to switch to the target cell or redirect to the target cell.
