Abstract

The invention discloses a mobile terminal and a data packet transmission method. The mobile terminal includes a first processing chip connected based on a preset interface, a second processing chip, a first radio frequency module and a second radio frequency module. The first processing chip includes a first An application processor and a first modem connected to the first and second subscriber identification cards, the second processing chip includes a second application processor and a second modem; the first modem receives the data packet sent by the second modem through a preset interface and obtains Request, obtain the data packet from the first or second subscriber identity card; split the extracted data packet, and add the same identification information to each sub-packet after splitting to cache to the temporary buffer of the preset interface buffer, for the second modem to extract each sub-packet and combine it according to the same identification information. It avoids the situation that the terminal crashes due to the excessive packet capacity value during the data packet transmission process.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a data packet transmission 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 p...
