Abstract

The embodiment of the invention discloses a data routing method and a terminal, and the method comprises the steps: obtaining a target identifier of a received target data packet, determining a targetnetwork interface card corresponding to the target identifier, and sending the target data packet through the target network interface card. The method disclosed by the embodiment of the invention has the beneficial effects that the method is adopted; the terminal is connected to a plurality of data networks according to the needs of service types. the terminal determines the corresponding targetnetwork interface card through the target identifier; if yes, the terminal can send the target data packet to a data network capable of serving the target data packet through the target network interface card; therefore, when the terminal accesses a plurality of data networks, the target data packet can be accurately sent to the corresponding data network without complex change of the code of theapplication program.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data routing method and a terminal. Background technique [0002] In the fifth-generation mobile communication technology (5th-generation, 5G) standard, the concept of network slice (network slice, NS) is proposed, which means that an operator's network can be divided into multiple network slices according to user groups or service types. Each network slice can contain one or more data networks (data network, DN). The terminal can access multiple network slices at the same time, and the terminal can establish communication connections with multiple data networks, and the link of each communication connection corresponds to a network interface card (network interface card, NIC) on the terminal. This will lead to a problem: when the terminal sends uplink data, how should the terminal select the NIC to send the data. [0003] The technical solution adopted i...
