Data packet processing method and related device

A mobile terminal, comprising:

• a memory configured to store an instruction;
• an application processor;
• and
• a modem coupled to the memory, the modem configured to:
• receive an Internet Protocol (IP) data packet from a network;
• determine an online status of a data service of the mobile terminal;
• process the IP data packet based on a transfer protocol type of the IP data packet when it is determined that the data service of the mobile terminal is not in an online state, wherein the modem does not forward the IP data packet to the application processor when it is determined that the data service of the mobile terminal is not in the online state;
• detect whether a destination IP address of the IP data packet is the same as one of a plurality of local IP addresses of the mobile terminal when it is determined that the data service of the mobile terminal is in the online state;
• and
• process the IP data packet based on the transfer protocol type of the IP data packet when it is detected that the destination IP address of the IP data packet is different from any one of the plurality of local IP addresses of the mobile terminal, wherein the modem does not forward the IP data packet to the application processor of the mobile terminal when it is detected that the destination IP address of the IP data packet is different from any one of the plurality of local IP addresses of the mobile terminal.

A nonvolatile non-transitory computer readable storage medium comprising one or more programs which when executed by a mobile terminal comprising a modem and an application processor, cause the mobile terminal to:

• receive an Internet Protocol (IP) data packet from a network;
• determine an online status of a data service of the mobile terminal;
• process the IP data packet based on a transfer protocol type of the IP data packet when it is determined that the data service of the mobile terminal is not in an online state, wherein the modem does not forward the IP data packet to the application processor when it is determined that the data service of the mobile terminal is not in the online state;
• detect whether a destination IP address of the IP data packet is the same as one of a plurality of local IP addresses of the mobile terminal when it is determined that the data service of the mobile terminal is in the online state;
• and
• process the IP data packet based on the transfer protocol type of the IP data packet when it is detected that the destination IP address of the IP data packet is different from any one of the plurality of local IP addresses of the mobile terminal, wherein the modem does not forward the IP data packet to the application processor of the mobile terminal when it is detected that the destination IP address of the IP data packet is different from any one of the plurality of local IP addresses of the mobile terminal.
