[0058] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0059] Currently, the frame routing processing mechanism in the 3GPP TS23.501 protocol is that after the customer terminal device (CPE) initiates a protocol data unit (PDU) session, the frame routing information of the CPE's hanging device is provided by the DN-AAA server or the unified data management function (UDM) to the session management function (SMF), and then the SMF is issued to the user plane function (UPF), and the UPF publishes the IP routing with IPv4 address or IPv6 prefix as the destination in the 5G network, and establishes a communication connection with the CPE's hanging device through the IP routing. However, in the case of changes in the internal networking architecture of the CPE's hanging device, the operator needs to update the subscription data of the DN-AAA or UDM, otherwise it will cause communication failure. In addition, the existing processing mechanism does not support publishing frame routing information to the CPE, and when the internal networking of the CPE's hanging device changes, the CPE still needs to be manually configured by the user to allocate the IPv4 address segment or IPv6 prefix consistent with the new frame routing information to the port of its hanging device, otherwise it will cause communication failure. Therefore, the traditional method will have an impact on 5G network communication in the case of changes in the internal networking architecture of the CPE's hanging device.

[0060] Figure 1 Schematic diagram of an application scenario of a service transmission method provided in an embodiment of the present application. Figure 1 As shown, the scenario includes a frame routing server 100, a customer premises equipment (CPE) 200, and a 5G core network element device 300. The CPE 200 is a device that converts 4G or 5G mobile signals into wireless WiFi signals and can support a large number of mobile terminals accessing the Internet simultaneously. The CPE can be widely used in areas with wireless network access, such as rural areas, towns, hospitals, units, factories, and residential areas. The CPE 200 can be connected to multiple downstream devices. The CPE 200 is in communication with the frame routing server 100 and the 5G core network element device 300, respectively. The frame routing server 100 can send frame routing information of the CPE 200's downstream devices to the CPE 200 and the 5G core network element device 300, respectively, so that the CPE 200 can connect the downstream devices to the 5G core network based on the frame routing information, thereby achieving communication connection between the downstream devices and the 5G core network.

[0061] Based on the above-mentioned traditional technology, an embodiment of the present application provides a method for determining frame routing information. When the CPE initiates a protocol data unit (PDU) session, a service request is sent to the frame routing server. The service request instructs the frame routing server to send the frame routing information of the CPE's downstream devices to the CPE and the 5G core network element respectively, so that the CPE and the 5G core network element can obtain the frame routing information of the CPE's downstream devices in a timely manner, and adaptively manage and match the frame routing information of the CPE's downstream devices, so that the CPE's downstream devices can be connected to the 5G core network based on the obtained frame routing information, ensuring the normal communication connection between the CPE's downstream devices and the 5G core network, and avoiding the impact of changes in the internal networking of the CPE's downstream devices on 5G network communication.

[0062] It should be noted that the beneficial effects or technical problems solved by the embodiments of the present application are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0063] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] In one embodiment,Figure 2 As shown, a frame routing information determination method is provided, and the method is applied to Figure 1 The method includes the following steps:

[0065] S201, in the case of initiating a protocol data unit (PDU) session, sending a service request to a frame routing server; the service request is used to instruct the frame routing server to send frame routing information of a device hung below the CPE to the CPE and a 5G core network element, respectively.

[0066] The PDU session refers to a communication process between the CPE and the 5G core network. After the PDU session is established, a data transmission channel between the CPE and the 5G core network is established. The PDU session information includes a number, a PDU session ID, a session type, an uplink and downlink rate, a charging ID, roaming state information, and IP information of the CPE. When the CPE has a service demand, an application for establishing a PDU session is initiated.

[0067] It should be noted that, in this embodiment, the frame routing refers to the IP routing of the device hung below the CPE. One frame routing corresponds to one IPv4 address segment or IPv6 prefix. One PDU session can be associated with multiple frame routings. The corresponding relationship between a certain PDU session and the multiple frame routings associated therewith is referred to as frame routing information. The frame routing server in this embodiment is a server preconfigured with the frame routing information of the device hung below the CPE. It can be understood that when the internal network of the device hung below the CPE changes, the frame routing information in the frame routing server can be reconfigured to ensure that when the internal network of the device hung below the CPE changes, the frame routing information in the frame routing server also changes. The frame routing server is configured with the latest frame routing information of the device hung below the CPE.

[0068] In this embodiment, when the CPE initiates a PDU session, the CPE sends a service request to the frame routing server through a communication connection between the CPE and the frame routing server. After receiving the service request, the frame routing server determines the current latest frame routing information of the device hung below the CPE in response to the service request, and sends the frame routing information to the CPE through the communication connection between the CPE and the frame routing server, and sends the frame routing information to the 5G core network element through the communication connection between the 5G core network element and the frame routing server.

[0069] S202, receiving the frame routing information sent by the frame routing server.

[0070] In this embodiment, after the CPE sends the above-mentioned service request to the frame routing server, the CPE receives the frame routing information of the device hung below the CPE sent by the frame routing server in response to the above-mentioned service request through the communication connection between the CPE and the frame routing server.

[0071] It can be understood that after the CPE receives the frame routing information sent by the frame routing server, the frame routing information can be parsed to obtain the frame routing in the frame routing information, so that the IPv4 address segment or the IPv6 prefix consistent with the parsed frame routing is allocated to the device port under the CPE according to the frame routing information.

[0072] S203, access the device under the CPE to the 5G core network based on the frame routing information.

[0073] It can be understood that the frame routing server sends the frame routing information of the device under the CPE to the CPE and the 5G core network element respectively in response to the service request sent by the CPE, so the 5G core network element can also update the subscription data of the DN-AAA or UDM according to the frame routing information of the device under the CPE sent by the CPE. After the CPE receives the frame routing information sent by the frame routing server, the frame routing information can be parsed to obtain the frame routing in the frame routing information, so that the IPv4 address segment or the IPv6 prefix consistent with the parsed frame routing is allocated to the device port under the CPE according to the frame routing information, realizing adaptive matching of the frame routing in the whole network, so that the CPE can access the device under the CPE to the 5G core network based on the frame routing information.

[0074] In the above method for determining the frame routing information, the customer terminal device sends a service request to the frame routing server in the case of initiating a protocol data unit (PDU) session, which can indicate the frame routing server to send the frame routing information of the device under the customer terminal device to the customer terminal device and the 5G core network element respectively, so that the customer terminal device and the 5G core network element can obtain the frame routing information of the device under the customer terminal device in time and adaptively manage and match the frame routing information of the device under the customer terminal device, so that the device under the customer terminal device can be accessed to the 5G core network based on the obtained frame routing information, ensuring the normal communication connection between the device under the customer terminal device and the 5G core network, and avoiding the impact on the 5G network communication in the case of internal network change of the device under the customer terminal device.

[0075] In the above scenario that the CPE accesses the device under the CPE to the 5G core network based on the received frame routing information, the CPE can update the port of the device under the CPE based on the received frame routing information, and access the device under the CPE to the 5G core network based on the updated port of the device under the CPE. In one embodiment, the above S203 comprises: updating the port of the device under the CPE based on the frame routing information, so as to access the device under the CPE to the 5G core network based on the updated port.

[0076] In the embodiment, the CPE can parse the received frame routing information, obtain the IP address included in the frame routing information, and update the port of the hung device by using the IP address, so as to access the hung device of the CPE into the 5G core network based on the updated port of the hung device.

[0077] Optionally, in the embodiment, the CPE can assign the port of the hung device corresponding to the IP address by using the IP address included in the frame routing information, and assign the IPv4 address segment or the IPv6 prefix consistent with the frame routing information sent by the frame routing server to the received frame routing information, so as to count the hung device of the CPE into the 5G core network based on the updated port.

[0078] In the embodiment, the CPE can update the port of the hung device based on the received frame routing information sent by the frame routing server, and the 5G core network element also receives the frame routing information of the hung device of the CPE sent by the frame server, so that the 5G core network element and the CPE can adaptively manage and match the frame routing information of the hung device of the CPE, thereby the hung device can be accessed into the 5G core network based on the updated port, and the normal communication connection between the hung device of the CPE and the 5G core network is ensured, and the influence on the 5G network communication caused by the change of the internal network of the hung device of the customer terminal device is avoided.

[0079] In one embodiment, as shown in Figure 3 , a method for determining frame routing information is provided, which is applied to a frame routing server in Figure 1 for example, and includes the following steps:

[0080] S301, receiving a service request sent by a customer terminal equipment CPE; wherein the service request is sent by the CPE in the case of initiating a protocol data unit PDU session.

[0081] The PDU session refers to the process of communication between the CPE and the 5G core network, and after the PDU session is established, a data transmission channel between the CPE and the 5G core network is established. The PDU session information includes number, PDU session ID, session type, uplink and downlink rate, charging ID, roaming state information, IP information of the CPE, and other related information. When the CPE has a service demand, it will initiate an application for establishing a PDU session.

[0082] In the embodiment, the CPE sends a service request to the frame routing server through a communication connection between the CPE and the frame routing server in the case of initiating a PDU session, and the frame server receives the service request sent by the CPE through a communication connection between the CPE and the frame server.

[0083] S302, in response to the service request, sending frame routing information of the CPE's hanging device to the CPE and the 5G core network element respectively, so that the CPE accesses the hanging device to the 5G core network based on the frame routing information.

[0084] It should be noted that in the embodiment, the frame routing refers to the IP routing of the CPE's hanging device, one frame routing corresponds to one IPv4 address segment or IPv6 prefix, and one PDU session can be associated with multiple frame routings. The correspondence between a certain PDU session and multiple frame routings associated therewith is referred to as frame routing information.

[0085] In the embodiment, the frame routing server is pre-configured with the frame routing information of the CPE's hanging device. When the internal network of the CPE's hanging device changes, the frame routing server can reconfigure the pre-configured frame routing information to ensure that the frame routing information in the frame routing server changes when the internal network of the CPE's hanging device changes. The frame routing server is configured with the latest frame routing information of the CPE's hanging device.

[0086] In the embodiment, after the frame server receives the service request, the frame routing information of the CPE's hanging device is determined in response to the service request, and the frame routing information is sent to the CPE through the communication connection between the CPE and the CPE, and the frame routing information is sent to the 5G core network element through the communication connection between the CPE and the 5G core network element.

[0087] In the above method of determining the frame routing information, the client terminal device sends a service request to the frame routing server when initiating a protocol data unit (PDU) session. After receiving the service request, the frame routing server can send the frame routing information of the client terminal device's hanging device to the client terminal device and the 5G core network element in response to the service request. The client terminal device and the 5G core network element can obtain the frame routing information of the client terminal device's hanging device in time and adaptively manage and match the frame routing information of the client terminal device's hanging device, so that the client terminal device can access the 5G core network based on the obtained frame routing information, ensuring normal communication connection between the client terminal device's hanging device and the 5G core network, and avoiding the impact of changes in the internal network of the client terminal device's hanging device on 5G network communication.

[0088] In the above scenario where the frame routing server sends the frame routing information of the CPE's hanging device to the CPE and the 5G core network element in response to the received service request, the frame routing information of the CPE's hanging device is pre-configured in the frame routing server. In one embodiment, as shown in Figure 4 the above method further comprises:

[0089] S401, receiving configuration information.

[0090] The configuration information is frame routing information of the CPE's hanging device. In this embodiment, as an optional implementation, the configuration information can be generated and input into the frame routing server according to the frame routing information of the CPE's hanging device after the change by the user in the case of detecting that the internal network of the CPE's hanging device changes; or, as another optional implementation, the configuration information can also be sent to the frame routing server by the CPE in the case of detecting that the internal network of the CPE's hanging device changes.

[0091] S402, configuring the frame routing information of the CPE's hanging device based on the configuration information.

[0092] In this embodiment, the frame routing server can parse the received configuration information, determine the frame routing information of the CPE's hanging device after the change, and configure the frame routing information of the CPE after the change based on the configuration information, so that the latest frame routing information of the CPE's hanging device is configured in the frame routing server.

[0093] In this embodiment, the frame routing server can configure the frame routing information of the CPE's hanging device based on the received configuration information, so that the latest frame routing information of the CPE's hanging device is configured in the frame routing server, and the accuracy of the frame routing information of the CPE's hanging device configured in the frame routing server is ensured.

[0094] In the above scenario that the frame server sends the frame routing information of the CPE's hanging device to the CPE and the 5G core network element respectively in response to the service request sent by the CPE, the frame server can send the frame routing information to a specific network element in the 5G core network element. In one embodiment, the above S302 includes: sending the frame routing information to a network exposure function platform NEF of the CPE and the 5G core network respectively in response to the service request.

[0095] The network exposure function (Network Exposure Function, NEF) is located between the 5G core network and the frame routing server, and is responsible for managing the external opening network data of the 5G core network. All external applications that want to access the internal data of the 5G core network must pass through the NEF, and the NEF provides corresponding security protection to ensure the security of the external application to the 3GPP network.

[0096] In the embodiment, the frame routing server sends the frame routing information of the CPE's hanging device to the CPE and the NEF of the 5G core network respectively in response to the service request sent by the CPE, and the NEF of the 5G core network distributes the frame routing information of the CPE's hanging device to other network elements of the 5G core network based on the 5G standard protocol.

[0097] In the embodiment, the frame routing server sends the frame routing information to the CPE and the NEF of the 5G core network respectively in response to the service request sent by the CPE, so that the CPE and the network elements of the 5G core network can obtain the frame routing information of the CPE's hanging device in time and adaptively manage and match the frame routing information of the CPE's hanging device, thereby enabling the CPE to access the 5G core network based on the obtained frame routing information, ensuring the normal communication connection between the CPE's hanging device and the 5G core network, and avoiding the influence on the 5G network communication in the case that the internal networking of the CPE's hanging device changes.

[0098] In one embodiment, as shown in Figure 5 , a method for determining frame routing information is provided, which is applied to the 5G core network elements in Figure 1 for example, and includes the following steps:

[0099] S501, receiving the frame routing information of the CPE's hanging device sent by the frame routing server; the frame routing information is sent by the frame routing server to the CPE and the 5G core network elements respectively in response to the service request sent by the CPE; the service request is sent by the CPE to the frame routing server in the case of initiating a protocol data unit (PDU) session.

[0100] The PDU session refers to the communication process between the CPE and the 5G core network, and after the PDU session is established, a data transmission channel between the CPE and the 5G core network is established. The PDU session information includes number, PDU session ID, session type, uplink and downlink rate, charging ID, roaming state information, IP information of the CPE, and other related information. When the CPE has a service demand, it will initiate an application for establishing a PDU session.

[0101] It should be noted that in the embodiment, the frame routing refers to the IP routing of the CPE's hanging device, one frame routing corresponds to one IPv4 address segment or IPv6 prefix, one PDU session can be associated with multiple frame routings, and the correspondence between a certain PDU session and multiple frame routings associated therewith is referred to as frame routing information. The frame routing server in the embodiment is a server preconfigured with the frame routing information of the CPE's hanging device. It can be understood that when the internal networking of the CPE's hanging device changes, the frame routing information in the frame routing server can be reconfigured to ensure that when the internal networking of the CPE's hanging device changes, the frame routing information in the frame routing server also changes, and the frame routing server is configured with the latest frame routing information of the CPE's hanging device.

[0102] In the embodiment, when the CPE initiates a PDU session, the CPE sends a service request to the frame routing server through a communication connection between the CPE and the frame routing server. After receiving the service request, the frame server determines the current latest frame routing information of the CPE's hanging device in response to the service request, and sends the frame routing information to the CPE through a communication connection between the CPE and the frame routing server, and sends the frame routing information to the 5G core network element through a communication connection between the 5G core network element and the frame routing server. The 5G core network element receives the frame routing information of the CPE's hanging device sent by the frame routing server. Optionally, in the embodiment, the frame routing information of the CPE's hanging device sent by the frame routing server can be received through the network exposure function (Network Exposure Function, NEF) network element of the 5G core network.

[0103] S502, access the hanging device to the 5G core network based on the frame routing information.

[0104] In the embodiment, after the 5G core network element receives the frame routing information of the CPE's hanging device sent by the frame routing server, the frame routing information of the CPE's hanging device can be distributed in the 5G core network. After the 5G core network receives the frame routing information, the 5G core network can establish a communication connection with the CPE's hanging device based on the frame routing information, and access the CPE's hanging device to the 5G core network.

[0105] In the method for determining the frame routing information, the CPE sends a service request to the frame routing server in the case of initiating a protocol data unit (PDU) session, and the frame routing server sends the frame routing information of the CPE's hanging device to the CPE and the 5G core network element in response to the service request. The 5G core network element can obtain the frame routing information of the CPE's hanging device in time and adaptively manage and match the frame routing information of the CPE's hanging device, so that the CPE can access the 5G core network based on the obtained frame routing information, and ensure the normal communication connection between the CPE's hanging device and the 5G core network, thereby avoiding the impact of the internal network change of the CPE's hanging device on the 5G network communication.

[0106] After the 5G core network element receives the frame routing information of the CPE's hanging device sent by the frame routing server, the frame routing information can be sent to other network elements. In one embodiment based on the above embodiment, the method further includes sending the frame routing information to a session management function (SMF).

[0107] In the above embodiment, the session management function (SMF) is a core network element of the 5G core network, responsible for session management related functions. In this embodiment, after the 5G core network element receives the frame routing information of the CPE's hanging device sent by the frame routing server, the 5G core network element can send the received frame routing information to the SMF according to the 5G protocol standard. The SMF sends the frame routing information to a user plane function (UPF), and the UPF sends the IP routing in the frame routing information to the 5G core network, so that the 5G core network obtains the frame routing information of the CPE's hanging device.

[0108] In this embodiment, after the 5G core network element receives the frame routing information of the CPE's hanging device sent by the frame routing server, the frame routing information is sent to the SMF of the 5G core network based on the 5G protocol standard, so that the 5G core network can obtain the frame routing information of the CPE's hanging device in time. In addition, the CPE can also receive the frame routing information of the CPE's hanging device sent by the frame routing server, so that the CPE and the 5G core network can obtain the frame routing information of the CPE's hanging device in time, and adaptively manage and match the frame routing information of the CPE's hanging device. Therefore, the CPE can access the CPE's hanging device to the 5G core network based on the obtained frame routing information, ensuring the normal communication connection between the CPE's hanging device and the 5G core network, and avoiding the influence of the internal network change of the CPE's hanging device on the 5G network communication.
