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, a first modem embedded with a virtual subscriber identification card, a first radio frequency module, and A 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 subscriber identity card or the physical subscriber identity card; compress the extracted data packet and cache it in the temporary buffer buffer of the preset interface, so that the second application processor can extract it from the buffer The compressed data packet to complete the transmission of the data packet. The invention avoids the situation that the terminal crashes due to too large packet capacity 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...
