Engineering Contradiction Analysis
1Reliability
If base stations perform tunnel negotiation and upper-layer protocol encapsulation with strong computing capability, then QoS requirements can be met, but deployment costs increase and extensive deployment cannot be achieved
Solution Approach 1:
The patent extracts the tunnel negotiation and protocol encapsulation functions from the base station and relocates them to the core network gateway. This separation allows base stations to use simpler, lower-cost hardware while the core network handles the computationally intensive tasks, thereby reducing deployment costs while maintaining QoS requirements.
Solution Approach 2:
The patent introduces a core network gateway as an intermediary between the base station and the external network. The gateway performs tunnel negotiation and protocol encapsulation, acting as a mediator that offloads computational tasks from the base station, enabling cost-effective deployment while ensuring QoS through centralized control.
2Stability of the object's composition
If forwarding resources are fixed in the network, then network stability is maintained, but forwarding resources cannot be adjusted based on service requirements
Solution Approach 1:
The patent implements dynamic forwarding resource allocation by allowing the core network gateway to negotiate tunnels and establish forwarding paths based on real-time service requirements. The forwarding resources are no longer fixed but can be dynamically adjusted through tunnel negotiation and path computation, enabling the network to adapt to varying service demands while maintaining stability through controlled management.
Solution Approach 2:
The patent changes the forwarding resource parameters from fixed to variable by introducing tunnel-based forwarding where resource allocation can be modified through negotiation. The core network gateway can adjust tunnel parameters, bandwidth allocation, and path selection based on service requirements, enabling flexible resource adjustment while maintaining network stability through protocol-controlled changes.
3Manufacturing precision
If base stations have strong computing capability for protocol encapsulation, then packet processing quality is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex protocol encapsulation and tunnel negotiation functions from the base station and relocates them to the core network gateway. This separation simplifies the base station design, reducing device complexity, while the core network gateway handles the sophisticated packet processing to maintain high processing quality.
Solution Approach 2:
The core network gateway acts as an intermediary that performs the complex upper-layer protocol encapsulation and tunnel negotiation. This mediator approach allows the base station to remain simple while the gateway ensures high packet processing quality through centralized intelligent handling of complex protocols.

AI summary
This application relates to a packet processing method. Before sending a service packet, a terminal device sends, to a server, a request packet for requesting the server to allocate an identifier of a network slice, and the server allocates the identifier of the network slice to the terminal device based on a service type of the terminal device and sends the identifier of the network slice to a control device. The control device determines parameter information of the network slice based on the identifier of the network slice and determines a forwarding path based on the parameter information. Then, the control device adds a forwarding resource included in the forwarding path to a forwarding resource of the network slice. When the terminal device sends the service packet, the service packet is forwarded by using the forwarding resource of the network slice. In the foregoing solution, the control device dynamically determines the forwarding resource for the network slice based on a service requirement, so that a forwarding resource in a network can be fully used, saving forwarding resource and improving network flexibility.
