[0039] To meet the needs of integrated ground-to-space network connectivity, satellite internet utilizes both a terrestrial core network and an onboard network, thus also requiring interoperability with roaming networks. Currently, satellite internet, as a VPLMN, cannot effectively support QoS guarantees for terrestrial HPLMN users during roaming, thus reducing communication performance.

[0040] Based on this, in each embodiment of the present application, when the terminal accesses the VPLMN via satellite, the first core network device belonging to the terminal's HPLMN receives the VPLMN-related network performance monitoring data reported by the VPLMN's second core network device. Based on the above solution, in the scenario where the terminal roams to the satellite Internet on a different network, the terrestrial core network device of the terminal's HPLMN can obtain the VPLMN-related network performance monitoring data, thereby effectively providing QoS guarantees for the terminal and improving communication performance.

[0041] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0042] First, the scenario of inter-network roaming between the satellite Internet and the terrestrial core network (hereinafter referred to as inter-network roaming between the satellite and terrestrial core networks) involved in the embodiment of the present application is described. In the inter-network roaming between the satellite and terrestrial core networks, the satellite Internet, as a VPLMN, has an onboard network and a terrestrial core network. Users of the terrestrial HPLMN access the terrestrial network of the satellite Internet through roaming. Figure 1 shows the network architecture in the inter-network roaming scenario between the satellite and terrestrial core networks. In Figure 1, the left rectangular box is the satellite Internet network, that is, the satellite VPLMN, and the terrestrial cellular network in the right rectangular box is the terrestrial network, that is, the terrestrial HPLMN. The access networks and core networks of the operators of the VPLMN and the HPLMN are independently constructed and managed, and the users of the operators are independently managed. The equipment between the operators is connected through the Internet Protocol Version 6 (IPv6) interface and deployed through the Security Edge Protection Proxy (SEPP). In an embodiment of the present application, when the terminal is in a roaming scenario between the satellite-ground core network and the satellite Internet, as a VPLMN, needs to support QoS guarantees for ground HPLMN users, and needs to monitor and report network performance in real time for satellite resource allocation of the satellite Internet.

[0043] Based on the above-mentioned satellite-to-ground core network roaming scenario, an embodiment of the present application provides a network performance monitoring method, which is applied to a first core network device; the first core network device belongs to the terminal's HPLMN, that is, the first core network device is the core network device of the terminal's terrestrial HPLMN, the VPLMN accessed by the terminal is a satellite internet network, and the second core network device belongs to the terminal's VPLMN, that is, the second core network device is the terrestrial core network device of the terminal's VPLMN. As shown in Figure 2, the method includes:

[0044] Step 201: When the terminal accesses a VPLMN via a satellite, network performance monitoring data related to the VPLMN is received from a second core network device of the VPLMN.

[0045] In actual application, the terminal, i.e., the terrestrial HPLMN user, accesses the network via satellite and requests to establish a PDU session. At this time, the second core network device sends a PDU session creation request to the first core network device, requesting to create a PDU session for the terminal. The first core network device receives the PDU session creation request of the terminal sent by the second core network device, and the PDU session creation request carries the PLMN ID of the terminal. Here, the first core network device learns that the PLMN ID of the terminal carried in the session creation request is the PLMN ID of the satellite internet network, thereby determining that the terminal accesses the network via satellite, i.e., the terminal is in a scenario of roaming between the satellite and ground core networks. Then, at this time, the first core network device receives the network performance monitoring data related to the satellite internet network reported by the second core network device. As a result, the first core network device can provide QoS guarantee for the terminal based on the network performance monitoring data reported by the second core network device.

[0046] In actual application, the first core network device may be a ground SMF, and the second core network device may be an onboard SMF. After receiving the PDU session creation request, the ground SMF interacts with the ground PCF to subscribe to or update the data of the terminal.

[0047] In an embodiment of the present application, a terrestrial HPLMN user accesses a satellite internet network, and network performance monitoring data related to the satellite VPLMN is transmitted to the terrestrial core network of the satellite internet network. Then, through roaming, the network performance monitoring data is transmitted from the terrestrial core network of the satellite internet network to the core network of the terrestrial HPLMN.

[0048] In one embodiment, the network performance monitoring data is reported at one or more of the terminal (perUE), network node (perNode), PDU session (perSession) and data flow (perFlow) as the reporting granularity, wherein when the network node is used as the reporting granularity, the network node can be an onboard NG-RAN and / or a satellite observation station.

[0049] In one embodiment, the network performance monitoring data includes one or more of bandwidth, rate and latency.

[0050] That is, the reported content of the network performance monitoring data includes but is not limited to the bandwidth, rate, and latency related to the VPLMN.

[0051] There are two ways to report network performance monitoring data: one is through the network side, and the other is through the network management system. The following describes these two reporting methods in detail.

[0052] First, the network side reports. In one embodiment, receiving the VPLMN-related network performance monitoring data reported by the second core network device of the VPLMN includes:

[0053] The network performance monitoring data related to the VPLMN is obtained from the second UPF through the first UPF.

[0054] Among them, the first UPF belongs to the HPLMN, that is, the first UPF is the UPF of the terrestrial network; the second UPF represents the terrestrial UPF of the VPLMN, that is, the second UPF is the UPF of the terrestrial core network of the satellite Internet network.

[0055] Here, as shown in Figure 3, an N9 interface is created between the first UPF and the second UPF. In actual application, the network performance monitoring data related to the VPLMN is collected by the onboard RAN and sent to the second UPF through the N3 interface. Afterwards, the first UPF obtains the network performance monitoring data related to the VPLMN from the second UPF through the N9 interface, and the first UPF sends the obtained network performance monitoring data to the data network (DN) through the N6 interface to perform relevant statistics on the network performance monitoring data.

[0056] Figure 4 shows the interaction process reported by the network side:

[0057] Step 0: The terminal accesses the VPLMN via satellite.

[0058] Step 1: The SMF of the VPLMN sends a PDU session creation request to the SMF of the HPLMN of the terminal.

[0059] Step 2: The SMF of the HPLMN requests the PCF to subscribe to the terminal's data or update the subscription data.

[0060] Step 3: The HPLMN's SMF determines that the terminal accesses the VPLMN via satellite based on the PLMN ID carried in the PDU session creation request, thereby triggering network performance monitoring and selecting the UPF to interact with the VPLMN.

[0061] Step 4: The HPLMN's SMF sends an N4 session creation request to the UPF.

[0062] Step 5: The UPF of the HPLMN returns an N4 session creation response to the SMF.

[0063] Step 6: An N9 interface is created between the UPF of the HPLMN and the UPF of the VPLMN, so that the UPF of the HPLMN can obtain network performance monitoring data related to the VPLMN.

[0064] Step 7: The VPLMN supports statistics on VPLMN-related network performance monitoring data and opens the statistical data to the UPF of the HPLMN.

[0065] Step 8: The UPF of the HPLMN obtains the statistical data of the VPLMN and aggregates it with the network performance monitoring data from the UPF to the DN.

[0066] Step 9: The SMF of the HPLMN returns a PDU session creation response to the SMF of the VPLMN.

[0067] In this way, based on the created PDU session, data is exchanged between the terminal and the UPF of the HPLMN.

[0068] In one embodiment, before receiving the VPLMN-related network performance monitoring data reported by the second core network device of the VPLMN, the method further includes:

[0069] receiving, based on the SEPP, first information sent by the second core network device; wherein the first information indicates that the second core network device selects the second UPF for the terminal;

[0070] The first UPF is determined based on the second UPF.

[0071] In practical applications, satellite internet supports the onboard SMF selecting a UPF for satellite access users, thereby triggering network performance monitoring. Specifically, as shown in Figure 3, the VPLMN's SEPP transmits first information indicating the UPF selected for the satellite access user to the terrestrial HPLMN's SEPP via the N32 interface. Based on this first information, the terrestrial SMF determines the terrestrial UPF for the satellite access user, facilitating the transmission of network performance monitoring data from the satellite VPLMN back to the terrestrial HPLMN.

[0072] Secondly, reporting is performed through a network management system. In one embodiment, receiving the network performance monitoring data related to the VPLMN reported by the second core network device of the VPLMN includes:

[0073] The network performance monitoring data related to the VPLMN is obtained from the second OAM through the first OAM.

[0074] The first OAM belongs to the HPLMN; the second OAM belongs to the VPLMN.

[0075] Here, the first OAM of the HPLMN and the second OAM of the VPLMN need to have the ability to interact. As shown in Figure 5, a new interface is added between the first OAM and the second OAM to enable the second OAM to open the network performance monitoring data related to the satellite VPLMN to the first OAM of the terrestrial HPLMN.

[0076] In an embodiment of the present application, based on the network performance monitoring data reported by the second core network device, the first core network device triggers QoS monitoring when it determines that network traffic is abnormal and / or session is abnormal and / or QoS parameters exceed thresholds and / or network performance does not meet expectations, and takes corresponding measures to adjust network resource allocation, optimize service quality, or notify troubleshooting and processing. Specifically, QoS monitoring can be triggered in the following four ways:

[0077] 1. Based on the QoS parameters contained in the network performance monitoring data reported by the second core network equipment, such as delay, packet loss rate, bandwidth utilization, etc., the service quality is evaluated and QoS monitoring is triggered;

[0078] 2. Preset QoS threshold: Preset a QoS threshold in the first core network device. When the QoS parameters in the received network performance monitoring data exceed or fall below the corresponding set threshold, QoS monitoring is triggered;

[0079] 3. Automatic trigger mechanism: When network performance is detected to be abnormal or not in line with expectations, the QoS monitoring program is automatically triggered;

[0080] 4. Manual intervention: Allow network administrators or operation and maintenance personnel to manually trigger QoS monitoring when needed.

[0081] Based on the network performance monitoring method for the first core network device side of the above embodiment, the present embodiment also provides a network performance monitoring method applied to the second core network device of the terrestrial core network of the satellite internet network; the satellite internet network is the VPLMN accessed by the terminal. As shown in Figure 6, the method includes:

[0083] The first core network device belongs to the HPLMN of the terminal.

[0084] In one embodiment, reporting the satellite Internet-related network performance monitoring data to the first core network device includes:

[0085] The satellite Internet-related network performance monitoring data is sent to the first UPF through the second UPF.

[0086] The first UPF belongs to the HPLMN; the second UPF represents the terrestrial UPF of the VPLMN.

[0087] In one embodiment, before reporting the satellite Internet-related network performance monitoring data to the first core network device, the method further includes:

[0088] First information is sent to the first core network device based on SEPP; the first information represents the second UPF selected by the second core network device for the terminal.

[0089] In one embodiment, reporting the satellite Internet-related network performance monitoring data to the first core network device includes:

[0090] The satellite Internet-related network performance monitoring data is sent to the first OAM through the second OAM.

[0091] The first OAM belongs to the HPLMN; the second OAM belongs to the VPLMN.
