Mobile terminal and data packet transmission method

Abstract

The invention discloses a mobile terminal and a data packet transmission method. The mobile terminal comprises a first processing chip, a second processing chip, a first radio-frequency module and a second radio-frequency module; the first processing chip and the second processing chip are connected through a pre-set interface; the first processing chip comprises a first application processor, a first modem and a real subscriber identity module card; a virtual subscriber identity module card is embedded in the first modem; the real subscriber identity module card is connected with the first modem; the second processing chip comprises a second application processor and a second modem; the first modem receives a data packet obtaining request sent by the second modem through the pre-set interface, and extracts a data packet from the virtual subscriber identity module card or the real subscriber identity module card; the extracted data packet is compressed and cached in the temporary buffer of the pre-set interface, so that the second modem extracts the compressed data packet from the buffer; and thus, transmission of the data packet is completed. By means of the mobile terminal and the data packet transmission method disclosed by the invention, the problem that the terminal is crashed due to the fact that the packet capacity value is too high in the data packet transmission process can be avoided.

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...
