[0039] Facing the network connection demand of the integration of space and earth, the satellite Internet has both a ground core network and a network on the satellite, and therefore involves interconnection and intercommunication of different networks. At present, in the roaming state, the satellite Internet as a VPLMN cannot effectively support QoS guarantee for the ground HPLMN user, which reduces the communication performance.

[0040] Based on this, in the embodiments of the present application, the first core network device of the HPLMN of the terminal receives the network performance monitoring data related to the VPLMN reported by the second core network device of the VPLMN in the case that the terminal accesses the VPLMN through the satellite. Based on the above scheme, in the scenario that the terminal roams to the satellite Internet in a different network, the ground core network device of the HPLMN of the terminal can obtain the network performance monitoring data related to the VPLMN, so as to effectively guarantee the QoS of the terminal on this basis, and improve the communication performance.

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

[0042] Firstly, a scenario of inter-network roaming between satellite Internet and ground core network (hereinafter referred to as inter-network roaming of satellite-ground core network) related to the embodiments of the present application is described, wherein in the inter-network roaming of satellite-ground core network, the satellite Internet is a VPLMN, has a satellite network and a ground core network, and a user of a ground HPLMN accesses the ground network of the satellite Internet in a roaming manner. FIG. 1 shows a network architecture in the scenario of inter-network roaming of satellite-ground core network, in which the left rectangular box is a satellite Internet, that is, a satellite VPLMN, and the right rectangular box is a ground cellular network, that is, a ground 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 devices of the operators are connected through an Internet Protocol Version 6 (IPv6) interface and are deployed through a security edge protection proxy (SEPP). In the embodiments of the present application, when a terminal is in the scenario of inter-network roaming of satellite-ground core network, the satellite Internet as a VPLMN needs to support QoS guarantee for users of a ground HPLMN and needs to perform network performance monitoring and real-time reporting on satellite resource allocation of the satellite Internet.

[0043] Based on the above scenario of inter-network roaming of satellite-ground core network, the embodiments of the present application provide a network performance monitoring method applied to a first core network device. The first core network device belongs to a HPLMN of a terminal, that is, the first core network device is a core network device of a ground HPLMN of the terminal. A VPLMN to which the terminal accesses is a satellite Internet, and a second core network device belongs to the VPLMN of the terminal, that is, the second core network device is a ground core network device of the VPLMN of the terminal. As shown in FIG. 2, the method comprises the following steps:

[0044] Step 201: In a case where the terminal accesses a VPLMN through a satellite, receiving network performance monitoring data related to the VPLMN reported by a second core network device of the VPLMN.

[0045] In actual application, a terminal, i.e., a ground HPLMN user, accesses a satellite interconnection network 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 knows that the PLMN ID of the terminal carried in the session creation request is the PLMN ID of the satellite interconnection network, thereby judging that the terminal accesses the network through the satellite, i.e., the terminal is in the scenario of inter-network roaming between the ground core network and the satellite core network. At this time, the first core network device receives the network performance monitoring data related to the satellite interconnection network reported by the second core network device, and thus the first core network device can perform 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 can be a ground SMF, and the second core network device can be a satellite SMF. After receiving the PDU session creation request, the ground SMF interacts with the ground PCF to perform data subscription or subscription data update of the terminal.

[0047] In the embodiment of the application, a ground HPLMN user accesses a satellite interconnection network, and network performance monitoring data related to a satellite VPLMN is transmitted to the ground core network of the satellite interconnection network, and then the network performance monitoring data is transmitted from the ground core network of the satellite interconnection network to the core network of the ground HPLMN through roaming.

[0048] In an embodiment, the network performance monitoring data has one or more of a terminal (perUE), a network node (perNode), a PDU session (perSession), and a data flow (perFlow) as a reporting granularity. In the reporting granularity of the network node, the network node can be a satellite NG-RAN and / or a satellite observatory.

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

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

[0051] The reporting manner of the network performance monitoring data includes two kinds: one is reported through the network side, and the other is reported through network management. The two reporting manners are described in detail as follows.

[0052] First, the network side reports, in an embodiment, the second core network device of the VPLMN reports the network performance monitoring data related to the VPLMN, including:

[0053] acquire the VPLMN-related network performance monitoring data from the second UPF through the first UPF.

[0054] The first UPF belongs to the HPLMN, that is, the first UPF is a UPF of a ground network; and the second UPF represents a ground UPF of the VPLMN, that is, the second UPF is a UPF of a ground core network of a satellite interconnection network.

[0055] Here, as shown in FIG. 3, an N9 interface is created between the first UPF and the second UPF. In actual application, the VPLMN-related network performance monitoring data is collected by a satellite RAN and sent to the second UPF through an N3 interface. Then, the first UPF acquires the VPLMN-related network performance monitoring data from the second UPF through the N9 interface, and sends the acquired network performance monitoring data to a data network (DN) through an N6 interface for related statistics of the network performance monitoring data.

[0056] FIG. 4 shows an interaction process of network-side reporting:

[0057] Step 0: The terminal accesses the VPLMN through a 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 a data subscription or a subscription data update of the terminal from the PCF.

[0060] Step 3: The SMF of the HPLMN determines that the terminal accesses the VPLMN through a satellite according to a PLMN ID carried in the PDU session creation request, thereby triggering network performance monitoring and selecting a UPF for interaction with the VPLMN.

[0061] Step 4: The SMF of the HPLMN 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: The UPF of the HPLMN creates an N9 interface with the UPF of the VPLMN, which is used for the UPF of the HPLMN to acquire VPLMN-related network performance monitoring data.

[0064] Step 7: The VPLMN supports statistics of the 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 acquires the statistics of the VPLMN and aggregates the network performance monitoring data of 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, the terminal and the UPF of the HPLMN perform data interaction.

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

[0069] The SEPP receives first information sent by the second core network device; the first information indicates that the second core network device selects the second UPF for the terminal;

[0070] The second UPF determines the first UPF.

[0071] In actual application, the satellite Internet supports the SMF on the satellite to select the UPF for the satellite access user, thereby triggering the network performance monitoring. Specifically, as shown in FIG. 3, the SEPP of the VPLMN transmits first information indicating the UPF selected for the satellite access user to the SEPP of the ground HPLMN through the N32 interface, so that the ground SMF determines the ground UPF for the satellite access user based on the first information, so that the network performance monitoring data can be transmitted from the satellite VPLMN back to the ground HPLMN.

[0072] Secondly, it is reported through network management. In an embodiment, receiving the network performance monitoring data related to the VPLMN reported by the second core network device of the VPLMN comprises:

[0075] Here, the first OAM of the HPLMN and the second OAM of the VPLMN need to have interaction capability. As shown in FIG. 5, an interface is added between the first OAM and the second OAM, so that the second OAM exposes the network performance monitoring data related to the satellite VPLMN to the first OAM of the ground HPLMN.

[0076] In the embodiments of the present application, the first core network device triggers QoS monitoring based on the network performance monitoring data reported by the second core network device, and takes corresponding measures to adjust network resource allocation, optimize service quality, or notify troubleshooting and processing when determining that network traffic is abnormal, and / or session is abnormal, and / or QoS parameter exceeds threshold, and / or network performance does not meet expectations. 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 device, such as delay, packet loss rate, bandwidth utilization, etc., the service quality is evaluated and QoS monitoring is triggered;

[0078] 2. Pre-set QoS threshold: pre-set QoS threshold in the first core network device, when the QoS parameter in the received network performance monitoring data exceeds or is lower than the corresponding set threshold, trigger QoS monitoring;

[0079] 3. Automatic triggering mechanism: when detecting that the network performance is abnormal or does not meet the expectation, automatically trigger the QoS monitoring program;

[0080] 4. Manual intervention: let the network administrator or operation and maintenance personnel manually trigger QoS monitoring when needed.
