and if the system running in the foreground in the multi-system terminal is switched from the first system to a second system, disconnecting the first identity identification card from the modem and establishing the connection between a second user identity identification card and the modem, wherein the second user identity identification card is used for sending a data packet generated by a second application of the second system to a second target network.
5. A communications apparatus, comprising:
the system comprises an operation module, a first network module and a second network module, wherein the operation module is used for operating a first application in a first system of the multi-system terminal, the first application comprises an identifier of a first target network, and the first system is a system which is operated in a foreground in the multi-system terminal;
a sending module, configured to send a data packet generated by the first application to the first target network through a first data communication interface pre-established in a first namespace corresponding to the first system, where the first data communication interface is used to connect the first namespace and a modem of the multi-system terminal;
a determining module, configured to determine a second data communication interface in a root namespace of the multi-system terminal, where the second data communication interface is used to connect the root namespace to the modem;
a generating module, configured to establish the first data communication interface in the first namespace according to the second data communication interface.
6. The apparatus of claim 5, wherein the sending module comprises:
a first transmission unit, configured to send the data packet to the modem through the first data communication interface;
a second transmission unit, configured to send the data packet to the first target network through a first identity card connected to the modem.
7. The apparatus of claim 5, further comprising:
a process connection module for connecting the first application to a communication process of a first target network;
a channel establishing module, configured to establish a signaling channel between the first application and the modem through a communication process of the first target network, where the signaling channel is used to establish or release a communication connection between the first target network and the multi-system terminal.
8. The apparatus of claim 6, further comprising:
and the reestablishing module is used for disconnecting the connection between the first identity identification card and the modem and establishing the connection between a second user identity identification card and the modem if the system running in the foreground in the multi-system terminal is switched from the first system to a second system, wherein the second user identity identification card is used for sending a data packet generated by a second application of the second system to a second target network.
