Abstract

The invention discloses a data packet transmission system and method, the system includes: a mobile terminal and an external device, the mobile terminal includes a first application processor embedded with a virtual subscriber identification card, a first modem, a first radio frequency module, and a The physical subscriber identity card connected to the first modem, the external device includes a second application processor, a second modem and a second radio frequency module; the first application processor receives a data packet acquisition request sent by the second application processor through a preset interface, Extract the corresponding data packet from the virtual or physical subscriber identity card and split it, and add the same identification information to each sub-packet after the split to cache it in the temporary buffer buffer of the preset interface for the second The application processor extracts each subpacket from the buffer, and combines them according to the same identification information. The invention avoids terminal crash caused by excessive packet capacity value during the data packet transmission process.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data packet transmission system and method. Background technique [0002] With the development of mobile communication technology, more and more mobile terminals such as smart phones have the function of dual-card dual-pass, so that users can establish a data service connection while realizing voice service standby. The mobile terminal usually has two subscriber identity cards and a modem connected to the two subscriber identity cards respectively. When the two subscriber identity cards are fully opened, one subscriber identity card (SIM1) can use 4G (the 4th Generation Mobile Communication Technology, No. Four-generation mobile communication technology), such as LTE (Long Term Evolution, long-term evolution technology) network, another subscriber identification card (SIM2) can only use 2G (2-Generation wireless telephone technology, second-generation mobile phon...
