For ease of understanding, before describing embodiments of the present disclosure, several terms referred to in the embodiments of the present disclosure are first explained as follows:
and (3) an OLT: english is called Optical LINE TERMINAL, chinese is called Optical line terminal, and is the core component of Optical access network.

The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.
First, an implementation system for forwarding PON network and 5G network data traffic shown in fig. 1 is provided in an embodiment of the present disclosure, and the system may be applied, but is not limited to, in a network architecture shown in fig. 2. The network architecture shown in fig. 2 is an intranet of a factory or an enterprise, and service data can be transmitted between a terminal and a service platform through a PON network or through a 5G network. Wherein, PON network includes: ONU network element and OLT network element; the 5G network includes: gNB network element and UPF network element.
As shown in fig. 1, the implementation system for forwarding PON network and 5G network data traffic provided in an embodiment of the present disclosure includes: an OLT network element 101 and a UPF network element 102 with built-in network switching control modules (Network Switcher Contorl Function, NSCF) 100; the network switching control module 100 is configured to: monitoring link quality of the PON network and the 5G network; when the link quality of the PON network is higher than that of the 5G network, migrating the service data to an OLT network element 101 of the PON network; the traffic data is migrated to the UPF network element 102 of the 5G network when the link quality of the 5G network is higher than the link quality of the PON network.
It should be noted that, in the embodiment of the present disclosure, the OLT network element 101 and the UPF network element 102 may interact with a handover signaling of a link between the PON network and the 5G network through an SC interface (Switcher Contorl, handover control interface), so as to ensure that a traffic can be identified after the link is switched, and may be identified: the non-switched traffic is 0 and the switched traffic is 1.
The implementation method for data traffic migration between the PON network and the 5G network provided by the embodiment of the disclosure needs to define a control signaling flow for switching between the PON network and the 5G network, and for the PON network, a terminal is always connected with an OLT network element by adopting a C-VLAN, and the OLT network element is connected with a service platform by adopting an S-VLAN; in specific implementation, the S-VLAN identifier may be set to 100 to represent that PON network link establishment is successful, and the S-VLAN identifier may be set to 50 to represent PON network link establishment release.
In one embodiment of the present disclosure, when service data needs to be migrated to the OLT network element 101 of the PON network, the UPF network element may send a first data migration request to the OLT network element 100, so that the OLT network element performs a service data migration operation according to the first data migration request, and migrates the service data to the OLT network element. In this embodiment, the UPF network element may further send a first notification message to the service platform to notify that the current service network has been switched to the PON network; after receiving the first notification message, the service platform returns a second notification message to the UPF network element so as to notify the service platform that the first notification message is received.
In another embodiment of the present disclosure, when service data needs to be migrated to the UPF network element 102 of the 5G network, the OLT network element may send a second data migration request to the UPF network element, so that the UPF network element performs a service data migration operation according to the second data migration request, and migrates the service data to the UPF network element. In this embodiment, the OLT network element sends a third notification message to the service platform to notify that the current service network has been switched to the 5G network; and after receiving the third notification message, the service platform returns a fourth notification message to the OLT network element so as to inform the service platform that the third notification message is received.
It should be noted that, in the embodiment of the present disclosure, the link quality monitored by the network handover control module 100 may include: link quality of uplink and/or downlink; the uplink is a link of the terminal transmitting service data to the service platform through the PON network or the 5G network; the downlink is a link through which the service platform transmits service data to the terminal via the PON network or the 5G network.
In particular implementations, depending on the traffic data transmitted, the link quality of the uplink and/or downlink may be optionally monitored, including but not limited to the following three cases: if the currently transmitted service data is uplink data sent to the service platform by the terminal, the link quality of an uplink can be monitored; if the currently transmitted service data is uplink data sent to the service platform by the terminal, the link quality of an uplink can be monitored; if the currently transmitted service data is uplink data sent to the service platform by the terminal, the link quality of the uplink can be monitored.
Those skilled in the art will appreciate that the number of terminals, OLT network elements, UPF network elements and service platforms shown in fig. 1 and 2 is merely illustrative, and that any number of terminals, OLT network elements, UPF network elements and service platforms may be provided as desired. The embodiments of the present disclosure are not limited in this regard.
Fig. 3 shows a control signaling interaction flow diagram for switching between an industrial PON network and a 5G network in an embodiment of the disclosure, as shown in fig. 3, NR, AMF, SMF and UPF are network elements of the 5G network; the OLT is a network element of the PON network; the industrial terminal can select a 5G network or a PON network to transmit service data with the service platform.
Taking the example of transmitting data (downlink data) from a service platform to an industrial terminal, when the service platform transmits the service data to the industrial terminal through a 5G network, if a UPF network element of the 5G network monitors that the current network needs to be switched, a data migration request (namely the first data migration request) is sent to an OLT network element of a PON network, so that the OLT network element changes the value of an identification S-VLAN to 100, and after the data migration is successfully executed, a response message of successful data migration is returned to the UPF network element. The UPF network element can inform the service platform that the link has migrated to the PON network link; the service platform replies a message that the received link has migrated to the PON network link to the UPF network element; the service platform switches the service data to the PON network channel, and the OLT network element returns data fingerprint information containing a switching identifier, a destination IP address before switching and a destination IP address after switching to the industrial terminal, so that a PON network link is established between the industrial terminal and the service platform.
When the service platform transmits service data to the industrial terminal through the PON network, if the OLT network element of the PON network monitors that the current network needs to be switched, a data migration request (namely the second data migration request) is sent to the UPF network element of the 5G network, so that the value of the modified identifier S-VLAN of the OLT network element is 50, after the data migration is successfully executed, the service platform returns a response message of successful data migration to the OLT network element and switches the service data to a 5G network channel, and the UPF network element returns data fingerprint information containing a switching identifier, a destination IP address before switching and a destination IP address after switching to the industrial terminal, so that a 5G network link is established between the industrial terminal and the service platform.
It should be noted that, when the PON network and the 5G network are switched, the service platform cannot sense the switching of the network data traffic, and for the 5G network, the network elements need to complete the transfer of the link information by a request/reply manner, so that the step of notifying the service platform that the link has been migrated is needed; whereas for PON networks, the S-VLAN identification of the OLT is already able to specify the service switch, so that the service platform need not be notified of the link switch.
In an industrial network, there are two scenarios:
1) Industrial high reliability transmission: the 5G network is used for bearing data connection of industrial field devices, and under the influence of air interface jitter and uncontrollable factors, the performance of the 5G network fluctuates, so that the capability of industrial data transmission cannot meet the service requirement, and normal production is affected.
2) And (3) flexible production: the layout of the production line is adjusted in real time according to the change of orders, and meanwhile, the access requirement of the industrial terminal is met by re-wiring, and the access mode of the industrial terminal is required to have flexible adjustment and switching capability because the production line is frequently adjusted to meet the requirement of flexible production.
In the embodiment of the disclosure, a PON network and a 5G network dual-connection are built in an intranet of a factory or an enterprise, and a functional network switching control module, such as network detection, network quality judgment, link switching signaling, is newly added in an OLT network element and a UPF network element, so that the network quality of the PON network and the 5G network is monitored in real time, and the network is switched to a link with good network quality in real time to transmit service data, thereby ensuring high reliability of an industrial network and flexible and convenient access capability of an industrial terminal.
Based on the same inventive concept, the embodiment of the disclosure also provides a method for implementing data traffic migration between a PON network and a 5G network, where the method may be executed by any electronic device having a computing processing capability.
Fig. 4 shows a flowchart of a method for implementing data traffic migration between a PON network and a 5G network in an embodiment of the present disclosure, as shown in fig. 4, where the method for implementing data traffic migration between a PON network and a 5G network in an embodiment of the present disclosure includes the following steps:
Step S402 monitors link quality of PON network and 5G network.
It should be noted that, the link quality monitored in the step S402 includes: link quality of uplink and/or downlink; the uplink is a link of the terminal transmitting service data to the service platform through the PON network or the 5G network; the downlink is a link through which the service platform transmits service data to the terminal via the PON network or the 5G network.
In implementations, various link index data of the PON network or the 5G network may be monitored to determine network quality of the PON network or the 5G network based on the link index data. The monitored link index data includes, but is not limited to: transmission bandwidth (uplink bandwidth, downlink bandwidth), transmission delay, packet loss rate, jitter rate, etc.
In step S404, when the link quality of the PON network is higher than that of the 5G network, the service data is migrated to the OLT element of the PON network.
In one embodiment of the present disclosure, the step S404 may be implemented by: a UPF network element sends a first data migration request to an OLT network element; and the OLT network element executes the migration operation of the service data according to the first data migration request.
Further, in some embodiments, the implementation method for forwarding PON network and 5G network data traffic provided in the embodiments of the present disclosure may further include the following steps: a UPF network element sends a first notification message to a service platform, wherein the first notification message is used for notifying that the current service network is switched to a PON network; and returning a second notification message to the UPF network element by the service platform, wherein the second notification message is used for notifying the service platform that the first notification message is received.
In step S406, when the link quality of the 5G network is higher than that of the PON network, the service data is migrated to the user plane function UPF element of the 5G network.
In one embodiment of the present disclosure, the step S406 may be implemented as follows: the OLT network element sends a second data migration request to the UPF network element; and executing the migration operation of the service data by the UPF network element according to the second data migration request.
Further, in some embodiments, the implementation method for forwarding PON network and 5G network data traffic provided in the embodiments of the present disclosure may further include the following steps: sending a third notification message to the service platform by the OLT network element, wherein the third notification message is used for notifying that the current service network is switched to the 5G network; and returning a fourth notification message to the OLT network element by the service platform, wherein the fourth notification message is used for notifying the service platform that the third notification message is received.

The following algorithm can be configured in the network handover control module:
1) The links of the PON network include: ①②③; the links of the 5G network include: ④⑤⑥ The judgment factors include: upstream bandwidth, downstream bandwidth, delay, packet loss, jitter.
2) Judging a link rule according to the service type:

And judging the link quality from the terminal to the service platform and from the service platform to the terminal according to the services (such as uploading industrial data and issuing machine operation instructions during industrial control) with the uplink and downlink flows.
3) The network quality calculation method can select a common algorithm: and when the quality of the 5G network is reduced and the quality of the PON network is not good, switching the service data from the 5G network to the PON network, and when the quality of the PON network is reduced and the quality of the 5G network is not good, switching the service data from the PON network to the 5G network.
