Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular to a method and system for managing N5CW equipment access to a core network. Background Art

[0002] Currently, the 5G (The 5th Generation Mobile Communication Technology) core network manages user data by allocating resources based on the contracted data of 5G users, such as QoS (Quality of Service) resources and slicing resources. The overall bandwidth of core network user data is planned based on hardware resources and user data volume.

[0003] When N5CW (Non-5G-Capable over WLAN) Wi-Fi devices are introduced into the 5G core network, 5G UEs and N5CW devices will simultaneously exchange data with the 5G core network, increasing the amount of data processed by the core network's data plane. To address the issue of insufficient uplink bandwidth for 5G NR (New Radio), N5CW devices are introduced into the 5G core network. While the high traffic generated by Wi-Fi devices meets users' uplink bandwidth needs, it also occupies network resources on the 5G core network's data plane devices. Without a specific resource management mechanism, insufficient bandwidth is easily available for 5G UEs.

[0004] Therefore, how to effectively manage data resource scheduling when 5G UEs access the 5G core network at the same time and ensure that 5G UE users have schedulable bandwidth has become an urgent problem to be solved. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] To address the insufficient uplink bandwidth of 5G NR, the 5G core network supports the access of N5CW devices. While increasing the system bandwidth, it also burdens the data plane processing capabilities of the core network. To ensure the normal access of each terminal device, especially to prioritize the data access of 5G UE, the present invention proposes a new access core network management method for N5CW devices.

[0035] Figure 1 This is one of the flow charts of the method for managing the access of N5CW equipment to the core network provided by the present invention, such as Figure 1 Shown, including:

[0036] Step S1: Wait for a wireless local area network N5CW WIFI device without 5G access capability to access and receive data transmission from the N5CW WIFI device;

[0037] Step S2: According to the system performance statistics, the access bandwidth of the N5CW WIFI device is dynamically adjusted based on the N5CW slice to enable normal access of the 5G user terminal UE.

[0038] Specifically, the N5CW WIFI device is normally connected to the 5G core network. After the connection is established, the 5G core network assigns the corresponding terminal identifier and corresponding slice information to the N5CWWIFI device.

[0039] At this time, the N5CW WIFI device and the ordinary 5G UE device access the 5G core network at the same time. The core network interacts with the above two types of devices at the same time and starts system performance statistics. If the system load is too high, it will start to control the access data of the N5CWWIFI device. The present invention dynamically adjusts the access bandwidth of the N5CW WIFI device through the slice information allocated to the N5CW WIFI device, that is, the N5CW slice, thereby reducing the overall load of the system to ensure normal access of the 5G UE.

[0040] The present invention sets specific slices for the N5CW device to ensure that when the 5G core network system bandwidth is overloaded, the throughput of the N5CW device can be adjusted to guarantee the throughput of the 5G UE.

[0041] Based on the above embodiment, the process before step S1 includes:

[0042] The N5CW WIFI device connects to a trusted WLAN access network TWAN device via WIFI and receives a registration request from the TWAN device;

[0043] Determine the WIFI terminal identifier of the N5CW WIFI device and allocate an S-NSSAI slice to the N5CW WIFI device.

[0044] Specifically, if Figure 2 As shown in the figure, the process of N5CW WIFI device accessing the 5G core network includes:

[0045] First, the N5CW WIFI device connects to the TWAN (Trusted WLAN Access Network) device via WIFI, and then TWAN initiates registration with the 5GC (5G Core Network). After receiving the registration request, the 5GC identifies the N5CW WIFI device registered with TWAN, allocates an S-NSSAI (Single Network Slice Selection Assistance Information) slice, and returns a registration success response to the TWAN device. At this point, the WIFI connection is established.

[0046] The present invention accesses the N5CW WIFI device through TWAN, and the 5G core network allocates proprietary slice information to the N5CW WIFI device, so that the system can dynamically control the access bandwidth of the N5CW WIFI device through the allocation and adjustment of slice resources when dynamically adjusting the bandwidth.

[0047] Based on any of the above embodiments, step S1 specifically includes:

[0048] Establishing a Stream Control Transmission Protocol (SCTP) connection with the TWAN device and returning a registration success response to the TWAN device;

[0049] Establish a connection with the N5CW WIFI device and receive a data service request initiated by the N5CW WIFI device.

[0050] Specifically, if Figure 2 As shown, after the N5CW WIFI device successfully connects to the 5GC, the N5CW WIFI device initiates a data service request to the TWAN device, and the TWAN device initiates a session establishment process to the 5GC. After the data session connection is successfully established, the N5CWWIFI device initiates data transmission to the 5GC.

[0051] The present invention manages the data services of N5CW WIFI devices accessing the 5G core network through TWAN devices, and realizes effective management of N5CW WIFI devices through terminal identification and slicing.

[0052] Based on any of the above embodiments, step S2 includes:

[0053] Receiving system bandwidth statistics from a user plane function (UPF), and if the system bandwidth exceeds a bandwidth threshold, receiving overload information reported by the UPF;

[0054] The N5CW slice is processed to reduce the access bandwidth of the N5CW WIFI device so that the system bandwidth is lower than the bandwidth threshold.

[0055] Specifically, when the N5CW WIFI device and the 5G UE device access the 5GC at the same time, the UPF (User Plane Function) counts the current system bandwidth in real time to confirm whether the system bandwidth exceeds the threshold. If it is determined to exceed the threshold, the UPF reports the overload information. After receiving the overload, the 5GC processes the N5CW slice to reduce the access bandwidth of the N5CW WIFI device, thereby reducing the overall bandwidth of the system, thereby ensuring that the 5G UE can transmit data normally.

[0056] This method identifies N5CW devices through the 5G core network and performs resource scheduling based on the number of activated devices in the system, real-time throughput, and overall system latency. This solves the problem of ensuring the core network's support for 5G UE data transmission and reception after bandwidth increases.

[0057] Based on any of the foregoing embodiments, processing the N5CW slice to reduce the access bandwidth of the N5CW WIFI device so that the system bandwidth is lower than the bandwidth threshold includes:

[0058] A protocol data unit (PDU) Modification is performed on the N5CW slice to reduce the maximum bit rate (MBR) of the N5CW slice, thereby reducing the access bandwidth of the N5CW WIFI device.

[0059] Specifically, when the system bandwidth reaches the threshold, the UPF reports overload information; after receiving the overload, the 5GC uniformly modifies the PDU (Protocol Data Unit) of the N5CW slices to reduce their MBR (Max Bit Rate), thereby reducing the WiFi traffic of the N5CW WiFi device, reducing the N5CW data bandwidth, and providing data forwarding guarantee for the 5GUE.

[0060] In the present invention, the 5G core network manages 5G UE and N5CW simultaneously. Both 5G UE and N5CW have large-bandwidth data passing through the 5G core network. When the data plane throughput of the 5G core network exceeds the threshold and causes overload, the N5CW device slices are uniformly scheduled for resources by identifying the N5CW device and counting the bandwidth of various data services to ensure the data forwarding performance requirements of the 5G UE.

[0061] Based on any of the above embodiments, the WIFI terminal identifier is used to distinguish N5CW users from 5G ordinary users.

[0062] Specifically, when 5GC establishes an SCTP coupling with TWAN, it is marked as a device connected to N5CW. 5GC distinguishes the user type based on the Wi-Fi terminal identifier, that is, determines whether it is an N5CW device or an ordinary 5G UE device.

[0063] The present invention allocates a WIFI terminal identifier to the N5CW WIFI device to distinguish it from ordinary 5G UE users, making it easier to control and adjust the corresponding network bandwidth resources using the allocated slice resources.

[0064] The following is a complete example to illustrate the solution process of the present invention. Figure 2 Shown, including:

[0065] Step 1: Connect the N5CW WIFI device to the TWAN device via WIFI.

[0066] Step 2: TWAN initiates registration with 5GC;

[0067] Step 3: After receiving the registration request, 5GC identifies the N5CW Wi-Fi device registered with TWAN and allocates S-NSSAI slices.

[0068] Step 4: Return a registration success response to the TWAN device;

[0069] Step 5: Complete the WiFi connection establishment between TWAN and N5CW WiFi device;

[0070] Step 6: The N5CW Wi-Fi device initiates a data service request to the TWAN device;

[0071] Step 7: The TWAN device initiates a session establishment process to the 5GC;

[0072] Step 8: After the data session connection is successfully established, the N5CW Wi-Fi device initiates data transmission to the 5GC.

[0073] Step 9: 5GC performs user plane performance statistics.

[0074] Step 10: 5GC detects user plane data overload;

[0075] Step 11: The 5GC performs PDU modification on the N5CW slice to reduce the MBR of the N5CW slice.

[0076] Step 12: TWAN controls the reduction of Wi-Fi traffic on the N5CW Wi-Fi device, thereby reducing the N5CW data bandwidth.

[0077] The present invention performs unified resource scheduling on N5CW device slices by identifying N5CW devices and counting the bandwidth of various data services to ensure the data forwarding performance requirements of 5G UE.

[0078] The N5CW device access core network management system provided by the present invention is described below. The N5CW device access core network management system described below and the N5CW device access core network management method described above can be referenced to each other.

[0079] Figure 3 This is a schematic diagram of the structure of the N5CW device access core network management system provided by the present invention, such as Figure 3 As shown, it includes: a receiving module 31 and an adjustment module 32, wherein:

[0080] The receiving module 31 is used to access the wireless local area network N5CW WIFI device without 5G access capability and receive the data transmission of the N5CW WIFI device; the adjustment module 32 is used to dynamically adjust the access bandwidth of the N5CW WIFI device based on the N5CW slice according to the system performance statistics, so that the 5G user terminal UE can access normally.

[0081] The present invention sets specific slices for the N5CW device to ensure that when the 5G core network system bandwidth is overloaded, the throughput of the N5CW device can be adjusted to guarantee the throughput of the 5G UE.

[0082] Based on the above embodiment, the system also includes a connection module 33, which is used for the N5CW WIFI device to connect to a trusted WLAN access network TWAN device via WIFI and receive a registration request from the TWAN device; determine the WIFI terminal identifier of the N5CW WIFI device, and allocate an S-NSSAI slice to the N5CW WIFI device.

[0083] The present invention accesses the N5CW WIFI device through TWAN, and the 5G core network allocates proprietary slice information to the N5CW WIFI device, so that the system can dynamically control the access bandwidth of the N5CW WIFI device through the allocation and adjustment of slice resources when dynamically adjusting the bandwidth.

[0084] Based on any of the above embodiments, the receiving module 31 is specifically configured to:

[0085] Establish a Stream Control Transmission Protocol (SCTP) connection with the TWAN device and return a registration success response to the TWAN device; establish a connection with the N5CW WIFI device and receive a data service request initiated by the N5CW WIFI device.

[0086] The present invention manages the data services of N5CW WIFI devices accessing the 5G core network through TWAN devices, and realizes effective management of N5CW WIFI devices through terminal identification and slicing.

[0087] Based on any of the above embodiments, the adjustment module 32 is specifically configured to:

[0088] Receive the system bandwidth counted by the user plane function UPF. If the system bandwidth exceeds the bandwidth threshold, receive the overload information reported by the UPF; process the N5CW slice and reduce the access bandwidth of the N5CW WIFI device so that the system bandwidth is lower than the bandwidth threshold.

[0089] This method identifies N5CW devices through the 5G core network and performs resource scheduling based on the number of activated devices in the system, real-time throughput, and overall system latency. This solves the problem of ensuring the core network's support for 5G UE data transmission and reception after bandwidth increases.

[0090] Based on any of the foregoing embodiments, the adjusting module 32 processes the N5CW slice to reduce the access bandwidth of the N5CW WIFI device so that the system bandwidth is lower than the bandwidth threshold, including:

[0091] A protocol data unit (PDU) Modification is performed on the N5CW slice to reduce the maximum bit rate (MBR) of the N5CW slice, thereby reducing the access bandwidth of the N5CW WIFI device.

[0092] In the present invention, the 5G core network manages 5G UE and N5CW simultaneously. Both 5G UE and N5CW have large-bandwidth data passing through the 5G core network. When the data plane throughput of the 5G core network exceeds the threshold and causes overload, the N5CW device slices are uniformly scheduled for resources by identifying the N5CW device and counting the bandwidth of various data services to ensure the data forwarding performance requirements of the 5G UE.

[0093] Based on any of the above embodiments, the WIFI terminal identifier is used to distinguish N5CW users from 5G ordinary users.

[0094] The present invention allocates a WIFI terminal identifier to the N5CW WIFI device to distinguish it from ordinary 5G UE users, making it easier to control and adjust the corresponding network bandwidth resources using the allocated slice resources.
