[0002] In the 5G base station traffic splitting technology, the base station can identify local services based on traffic splitting strategies, such as through IP quintuples, slice IDs, DNS (Domain Name System for short), etc., and split local services to local service servers. Figure 1 As a schematic diagram of the existing network architecture based on 5G base station traffic splitting, the base station splits local data to the local MEC (Mobile Edge Computing) edge cloud, and sends the data transmitted to the public network through the UPF (User Plane Function) to the Internet. There is an existing legal monitoring device in the DMZ (Demilitarized Zone) passed through to monitor the data transmitted to the public network. In this existing network based on 5G base station traffic splitting, local data will be directly unloaded locally, resulting in the inability to reasonably control this part of the data and there are certain security risks. Summary of the Invention

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0030] The specific implementation of the present invention will be described in detail in combination with specific embodiments as follows:

[0031] Example 1:

[0032] Figure 2 The implementation process of the local data monitoring method for a 5G base station provided in Embodiment 1 of the present invention is shown. For the sake of convenience of description, only the parts related to the embodiments of the present invention are shown and are described in detail as follows:

[0033] In step S201, receive the local service data transmitted between the user terminal and the MEC edge cloud, and copy the local service data;

[0034] The embodiments of the present invention are applicable to 5G base stations to monitor the service data sent by user terminals (UEs). After the 5G base station receives the local service data transmitted between the user terminal and the MEC edge cloud, it copies the local service data to obtain the copied local service data. Among them, the local service data transmitted between the user terminal and the MEC edge cloud can be the local service data sent by the user terminal to the MEC edge cloud, or the local service data sent by the MEC edge cloud to the user terminal. The MEC edge cloud is used to store local service data to improve the operation efficiency of the communication network and enhance the service distribution and transmission capabilities.

[0035] In a preferred embodiment, when receiving the local service data transmitted between the user terminal and the MEC edge cloud and copying the local service data, receive the terminal service data sending request of the user terminal, and determine whether the terminal service data is local service data or public network service data (for example, service data for accessing the Internet) according to the destination identification number in the terminal service data sending request. If it is determined that the terminal service data is local service data, send the terminal service data to the MEC edge cloud and copy the terminal service data, so as to copy the local service data sent by the user terminal to the MEC edge cloud while splitting the service data at the base station, providing a basis for subsequent monitoring of local service data. Among them, the destination identification number can be an IP five-tuple, a slice ID, a DNS, etc., for determining whether the terminal service data is local service data.

[0036] In another preferred embodiment, when receiving the local service data transmitted between the user terminal and the MEC edge cloud and copying the local service data, receive the local service data transmitted by the MEC edge cloud to the user terminal, send the local service data to the user terminal, and copy the local service data, so as to copy the local service data sent by the MEC edge cloud to the user terminal when the base station receives downlink service data, providing a basis for subsequent monitoring of local service data.

[0037] In step S202, the locally copied service data is sent to the monitoring device set in the DMZ so that the monitoring device can detect whether there is illegal information in the locally copied service data.

[0038] In the embodiment of the present invention, a monitoring device is set in the DMZ to ensure the security of the DMZ and the intranet data. After the 5G base station copies the locally copied service data, it sends it to the monitoring device set in the DMZ so that the monitoring device can detect whether there is illegal information in the locally copied service data, so that the monitoring device in the DMZ can uniformly monitor the locally copied service data and the public network service data. The illegal information can be harmful information such as porn, gambling, and drugs, or can be set according to the specific MEC edge cloud application scenario to achieve differentiated monitoring and improve the monitoring efficiency. Specifically, the 5G base station will be assigned an intranet IP address in the communication network. The monitoring device in the DMZ belongs to a public network device and will be assigned a public network IP address. When the base station forwards the locally copied service data to the monitoring device in the DMZ, it needs to go through internal IP conversion mapping in the base station before it can be forwarded to the monitoring device in the DMZ.

[0039] In step S203, if it is detected that there is illegal information in the locally copied service data, the corresponding session link of the locally copied service data between the user terminal and the MEC edge cloud is aborted.

[0040] In the embodiment of the present invention, if the monitoring device detects that there is illegal information in the locally copied service data, the 5G base station aborts the corresponding session link of the locally copied service data between the user terminal and the MEC edge cloud, thereby releasing the corresponding user terminal bearer and ensuring the data security of the user terminal and the security of the communication system where the 5G base station is located.

[0041] In one embodiment, if the monitoring device detects that there is illegal information in the locally copied service data, it sends a message indicating that illegal information has been detected in the locally copied service data to the 5G base station. At this time, the 5G base station aborts the corresponding session link of the locally copied service data between the user terminal and the MEC edge cloud, so that the 5G base station actively aborts the corresponding session link of the locally copied service data between the user terminal and the MEC edge cloud.

[0042] In another embodiment, if the monitoring device detects that there is illegal information in the locally copied service data, it sends a corresponding session link abort instruction to the 5G base station. When the 5G base station receives the corresponding session link abort instruction sent by the monitoring device, the 5G base station aborts the corresponding session link of the locally copied service data between the user terminal and the MEC edge cloud according to the session link abort instruction.

[0043] Specifically, when the base station receives a message indicating that illegal information exists in the local service data or a corresponding session link termination instruction, the base station maps the address information in the message or instruction fed back by the monitoring device in the DMZ to the user information connected to the base station, ensuring that a specific user and even the data session link of a specific user can be corresponded inside the base station, so as to accurately terminate the corresponding session link of the local service data between the user terminal and the MEC edge cloud.

[0044] In the embodiment of the present invention, when receiving the local service data transmitted between the user terminal and the MEC edge cloud, the local service data is copied, and the copied local service data is sent to the monitoring device set in the DMZ, so that the monitoring device can detect whether there is illegal information in the local service data. If it is detected that there is illegal information in the local service data, the corresponding session link of the local service data between the user terminal and the MEC edge cloud is terminated, thereby realizing the monitoring of the local service data transmitted between the user terminal and the MEC edge cloud based on the 5G base station, and improving the monitoring efficiency of the local service data.

[0045] Example 2:

[0046] Figure 3 The implementation process of the local data monitoring method of the 5G communication system provided by the second embodiment of the present invention is shown. For the sake of convenience of description, only the parts related to the embodiment of the present invention are shown and are described in detail as follows:

[0047] In step S301, the 5G base station receives the local service data transmitted between the user terminal and the MEC edge cloud, copies the local service data, and sends the copied local service data to the monitoring device set in the DMZ;

[0048] The embodiment of the present invention is applicable to a 5G communication system, which includes a 5G base station, an MEC edge cloud, and a monitoring device set in the DMZ to monitor the service data sent by a user terminal (UE). After receiving the local service data transmitted between the user terminal and the MEC edge cloud, the 5G base station copies the local service data to obtain the copied local service data, and sends the copied local service data to the monitoring device set in the DMZ, so that the monitoring device in the DMZ can uniformly monitor the local service data and the public network service data. Among them, the local service data transmitted between the user terminal and the MEC edge cloud can be the local service data sent by the user terminal to the MEC edge cloud, or the local service data sent by the MEC edge cloud to the user terminal. The MEC edge cloud is used to store the local service data to improve the operation efficiency of the communication network and enhance the service distribution and transmission capabilities.

[0049] In one embodiment, the 5G base station receives a terminal service data transmission request from a user terminal, and determines whether the terminal service data is local service data or public network service data (e.g., service data for accessing the Internet) according to the destination identification number in the terminal service data transmission request. If it is determined that the terminal service data is local service data, the 5G base station sends the terminal service data to the MEC edge cloud, copies the terminal service data, and sends the copied local service data to the monitoring device set in the DMZ. Thus, while the base station shunts the service data, it copies the local service data sent to the MEC edge cloud and sends it to the monitoring device, providing a basis for subsequent monitoring of local service data. The destination identification number can be an IP five-tuple, a slice ID, a DNS, etc., for determining whether the terminal service data is local service data.

[0050] In another preferred embodiment, the 5G base station receives local service data transmitted from the MEC edge cloud to the user terminal, sends the local service data to the user terminal, copies the local service data, and sends the copied local service data to the monitoring device set in the DMZ. Thus, when the base station receives downlink service data, it copies the local service data sent from the MEC edge cloud to the user terminal and sends it to the monitoring device set in the DMZ, providing a basis for subsequent monitoring of local service data.

[0051] In step S302, the monitoring device detects whether there is illegal information in the local service data. If it detects that there is illegal information in the local service data, it sends a session link termination instruction to the 5G base station;

[0052] In the embodiment of the present invention, a monitoring device is set in the DMZ to ensure the security of the DMZ and the internal network data. After receiving the copied local service data, the monitoring device detects whether there is illegal information in the local service data. If the monitoring device detects that there is illegal information in the local service data, it sends a session link termination instruction to the 5G base station. The illegal information can be harmful information such as porn, gambling, and drugs, or can be set according to the specific MEC edge cloud application scenario to achieve differentiated monitoring and improve the monitoring efficiency.

[0053] In step S303, the 5G base station terminates the corresponding session link of the local service data according to the session link termination instruction.

[0054] In the embodiment of the present invention, after receiving the session link termination instruction sent by the monitoring device, the 5G base station terminates the corresponding session link of the local service data according to the session link termination instruction, thereby releasing the corresponding user terminal bearer and ensuring the data security of the user terminal and the security of the communication system where the 5G base station is located.

[0055] After receiving the local service data transmitted between the user terminal and the MEC edge cloud in the 5G communication system according to an embodiment of the present invention, the 5G base station replicates the local service data, and sends the replicated local service data to the monitoring device set in the DMZ. The monitoring device detects whether there is illegal information in the local service data. If it detects that there is illegal information in the local service data, it sends a session link termination instruction to the 5G base station. The 5G base station terminates the corresponding session link of the local service data between the user terminal and the MEC edge cloud according to the session link termination instruction, thereby realizing the monitoring of the local service data transmitted between the user terminal and the MEC edge cloud based on the 5G base station, and improving the monitoring efficiency of the local service data.
