Engineering Contradiction Analysis
1Productivity
If data packets are processed by the access network side to optimize OTT service, then service quality is improved, but the network side cannot determine which data packets need to be processed
Solution Approach 1:
The patent introduces a capability exposure function device as an intermediary between the third-party application and the network side. This device receives processing policies from third-party applications, translates external identifiers to internal identifiers, and configures the policies on the network side, enabling the network to identify and process specific data packets without exposing internal network details to external applications.
2Productivity
If a processing policy is configured on the network side to process data packets, then data packet transmission efficiency is improved, but the system complexity increases due to identifier conversion and policy configuration
Solution Approach 1:
The capability exposure function device serves as a mediator that handles the complexity of identifier conversion and policy configuration. It translates external identifiers provided by third-party applications into internal network identifiers and manages the configuration of processing policies on network elements, thereby shielding the complexity from both the application and the core network infrastructure.
Solution Approach 2:
The system performs preliminary actions by pre-configuring processing policies on the network side before data packet transmission occurs. The capability exposure function device receives and processes policy configurations in advance, translating identifiers and setting up the necessary routing and processing rules, so that when data packets arrive, the network is already prepared to handle them efficiently.
3Speed
If mobile edge computing platform performs local routing on data packets, then routing efficiency is improved, but the platform cannot determine which data packets require local routing
Solution Approach 1:
The capability exposure function device acts as an intermediary that provides the mobile edge computing platform with the necessary information to make routing decisions. It translates external identifiers into internal identifiers that the edge platform can use to determine which data packets require local routing, enabling fast routing decisions without exposing the edge platform to the complexity of identifier management.

AI summary
The present invention discloses a data packet processing method and a device. The method includes: receiving, by a capability exposure function device, a first processing policy sent by a third-party application, where the first processing policy includes an external identifier of UE, an identifier of the third-party application, and a processing policy of a data packet sent by the UE to the third-party application; obtaining an internal identifier of the UE based on the external identifier of the UE; determining a second processing policy based on the internal identifier of the UE, where the second processing policy includes the internal identifier of the UE, the identifier of the third-party application, and the processing policy of the data packet; and configuring the second processing policy on a network side, where the second processing policy is used by a network side device to process the data packet.
