As shown in fig. 1, a schematic diagram of an existing 5G system architecture for handling time-sensitive network traffic is provided. The system architecture comprises a User terminal, base station Equipment, core network Equipment and a data network, wherein the terminal Equipment comprises a User Equipment (UE) and a Device-side adapter (Device-Side TSN Translator, DS-TT); the base station device may be a radio access network (Radio Access Network, RAN) device; a data network refers to a private or public network that provides some kind of data service, here representing a TSN network.
The core network device may be divided into a control plane network element device and a user plane network element device. The control plane network element device is mainly responsible for user access authentication, negotiating quality of service parameters (Quality of Service, qoS) with the base station and the user terminal, and transmitting a message forwarding control policy to the user plane network element, and specifically includes, but is not limited to, the following network elements: mobility management functions (Access and mobility Management Function, AMF), session management functions (Session Management Function, SMF), unified data management functions (Unified Data Management, UDM), policy control functions (Policy Control Function, PCF), TSN application functions (TSN Application Function, TSN AF).

The form lacks standard compatible interfaces with 5G system network side equipment, especially virtualized equipment, and cannot realize rapid and flexible integrated deployment. Meanwhile, under the condition that the network side adapter fails or the original network side adapter cannot meet the new service, the fast switching cannot be achieved.
Fig. 2 is a schematic diagram of a 5G system architecture with time-sensitive network capability according to the present invention. Compared with the 5G system architecture of FIG. 1, the invention adds a time-sensitive capability open management unit to manage one to a plurality of network side adapters and to open integration of the network side adapters and the 5G system. Compared with the fixed time-sensitive network side adapter integration application mode in the existing 5G system architecture, the scheme of the invention opens the integration capability of the network side adapter, performs unified management on the network side adapter, and selects the matched network side adapter to integrate into the 5G system according to the registration information, thereby realizing the integration capability opening of the time-sensitive network service of the 5G system and improving the flexibility of the time-sensitive network service deployment.
The following describes a method for opening the capability of a time-sensitive network according to the present invention with reference to fig. 3.
The method comprises the following steps:
step S301, responding to a time network capability registration request, and acquiring registration information of a network side adapter.
The time network capability registration request is issued by the network side adapter and one or more time capability registration requests may be received by the time sensitive capability openness management unit at the same time. The time network capability registration request includes registration information, which is extracted from the time network capability registration request by the time sensitive capability openness management unit. The registration information includes device information and capability parameters, the device information includes network interface information, such as device identifier, port address, port rate, port identifier, etc., and the capability parameters include time synchronization protocol supported by the network side adapter, type of 802.1Q protocol supported, qoS guarantee level, etc.
Step S302, a selection strategy is generated based on the registration information, and the optimal network side adapter is determined through the selection strategy.
The selection strategy comprises the following steps:
and checking the equipment information and the capability parameters, and selecting a network side adapter meeting the checking condition as a matched network side adapter.
Checking network interface information and capability parameters in the network side adapter equipment information, wherein the checking conditions comprise checking whether port rate meets the requirement of configuring the minimum rate, whether port address carrying is correct, whether supported time synchronization protocol meets the requirement of configuring the minimum version, whether supported 802.1Q protocol type meets the requirement of configuring, whether QoS guarantee level meets the requirement of configuring and the like. After the verification is completed, selecting the network side adapter meeting the verification condition as a matched network side adapter, and determining that the matched network side adapter is an optimal network side adapter when only one matched network side adapter exists.
Further, the selection policy further includes:
when a plurality of network side adapters exist, the network interface information and the capability parameters in the network side adapter equipment information are checked, and the checking conditions are the same as the above steps, and are not described herein.
When a plurality of network side adapters meeting the verification conditions exist, all the network side adapters meeting the verification conditions are placed in a registration list, and the optimal network side adapter is selected from the registration list through preset conditions. The preset conditions include the sequence of registration time, port rate level, 802.1Q protocol capability set coverage condition, qoS guarantee level capability and the like. And setting priority scale factors according to the importance degrees of different preset conditions, calculating the weighted priority of each network side adapter meeting the verification conditions through a weighted algorithm, and determining the network side adapter with the highest weighted priority as the optimal network side adapter.
Further, after determining the optimal network side adapter, the method further comprises the following steps:
step S303, sending a time network capability registration response to the optimal network side adapter.
Shi Min the capability openness management unit sends a time network capability registration response to the optimal network side adapter, informing the request result. The time network capability registration response result of the selected network side adapter comprises information such as successful registration, equipment activation information, capability selection list, 5GC system interface information and the like, so that the connection between the optimal network side adapter and the user terminal is convenient to follow. The time network capability registration response received by other matched network side adapters does not comprise equipment activation information and cannot be connected.
Step S304, the device information and the capability parameters of the optimal network side adapter are sent to the control plane functional module and the user plane functional module, so that the control plane functional module and the user plane functional module perform parameter matching and forwarding path planning.
Shi Min capability open management unit sends the device capability and information of the optimal network side adapter to control plane function module and user plane function module, mainly comprising the device capability of the optimal network side adapter, and after receiving the user terminal access signal, the control plane function module records and matches parameters of the control plane. And after receiving the access of the user terminal, the user plane function module performs user plane parameter matching and user plane forwarding path planning. The forwarding path rule includes configuring the next hop of the network traffic as the selected optimal network side adapter according to the device information of the optimal network side adapter, such as port type, port address, etc., notified by the time-sensitive capability openness management unit.
Step S305, a user terminal access signal is sent to the control plane function module, the user plane function module and the optimal network side adapter, and the control plane function module, the user plane function module and the optimal network side adapter perform user terminal access.
Further, after the user terminal is accessed, the method further comprises the following steps:
step S306, transmitting a forwarding signal to the user plane function module and the optimal network side adapter, so that the user plane function module and the optimal network side adapter perform forwarding processing of the user plane message.
After the user plane message is transmitted from the base station in the uplink direction, the user plane message is forwarded to a next hop network side adapter in the planned path after being processed by decapsulation, user matching, qoS mapping and the like of the user plane function, and the network side adapter is forwarded to a data network after being processed by time-sensitive QoS, such as traffic shaping, periodical queuing, frame preemption and the like. In the downlink direction, the optimal network side adapter receives the user plane message from the data network, and forwards the user plane message to the user plane function module after time-sensitive QoS processing, and the user plane function module forwards the base station after user matching, tunnel encapsulation and other processing, and the base station forwards the base station to the user terminal.
As shown in fig. 4, the present invention further provides a flowchart of a de-registration/deactivation step in a method for opening a capability of a time-sensitive network, which includes the following steps:
step S401, responding Yu Shimin network capacity de-registration request or time-sensitive network capacity de-activation request, and performing de-registration or de-activation on the current network side adapter;
the current network side adapter is the network side adapter that initiates the de-registration request or needs to perform the de-activation state, i.e. the second network side adapter 2 in fig. 4. When the current network side adapter fails to work normally, such as power failure, abnormal state and the like of an unrecoverable port, triggering the time-sensitive network capacity to register a request. The deregistration processing of the current network side adapter means that the time-sensitive capability open management unit eliminates the network side adapter which needs to be deregistered from the registration list.
When serious congestion is found, the network side adapter initiating the request can send out a time-sensitive network capability deactivation request to remove the activation state of the network side adapter and not exit the registration state, so that the subsequent time-sensitive capability opening management unit can select to activate the network side adapter again.
As a possible implementation manner, the time-sensitive network capability deactivation request is initiated by the current network side adapter, and may also be initiated by the time-sensitive capability openness management unit. When preset conditions change or network topology of the time-sensitive network changes and the like, and network side adapters need to be reselected, a time-sensitive network capacity deactivation request is sent to the network side adapters needing to be deactivated by the time-sensitive capacity opening management unit.
Step S402, based on the registration information and the selection policy, the optimal network side adapter is redetermined from the network side adapters which are in registration state except the current network side adapter.
And initiating reselection processing of the optimal network side adapter in the rest network side adapters in the registration state. According to the selection policy of step S302, the time-sensitive capability openness management unit reselects the optimal network side adapter, that is, the first network side adapter 1 in fig. 4, from the rest of network side adapters in the registered state, except the current network side adapter, in the registration list based on the registration information.
Step S403, activating the optimal network side adapter through the time-sensitive network capability activation request, and updating the state of the current network side adapter.
Shi Min the capability openness management unit sends a time-sensitive network capability activation request to the new optimal network side adapter, and instructs the optimal network side to perform an activation operation.
And step S404, after receiving the time-sensitive network capability activation request, the optimal network side adapter replies a time-sensitive network capability activation response to the time-sensitive capability opening management unit so as to inform the operation result of the time-sensitive capability opening management unit activation.
Step S405, the time-sensitive capability open management unit sends a time-sensitive network capability de-registration response or a de-activation response to the current network side adapter. The current network side adapter is a network side adapter which initiates a de-registration request or needs to be in a de-activation state, and the current network side adapter receives the de-registration request and then performs a state de-activation or de-registration operation.
Further, the method further comprises the following steps:
step S406, transmitting the equipment information and the capability parameters of the optimal network side adapter to the control plane function module and the user plane function module to perform parameter matching and user plane forwarding path planning;
and the control plane function module performs control plane parameter recording and matching, and the user plane network element performs user plane parameter matching and network path re-planning to update the newly matched network side adapter into the forwarding path.
Step S407, sending an information updating signal to the control surface functional module, the user surface functional module and the optimal network side adapter so that the control surface functional module, the user surface functional module and the optimal network side adapter update the user terminal information;
step S408, send the route updating signal to the user plane function module and the optimal network side adapter, so that the user plane function module and the optimal network side adapter update the user plane route. After the updating is completed, the user plane function and the reselected network side adapter can execute the user plane processing of the time sensitive service message according to the new path.
