Mobile terminal and data packet transmission method

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 an embedded The first application processor of the virtual subscriber identity card and the first modem connected with the first subscriber identity card and the second subscriber identity card, the second processing chip includes the second application processor and the second modem; The interface receives the data packet acquisition request sent by the second modem, and extracts the data packet from the first or second subscriber identification card; compresses the extracted data packet; and caches it in a temporary buffer buffer of the preset interface for the second The second modem extracts the compressed data packet from the buffer 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 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...
