Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039]A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be used mixedly.

[0040] figure 1 It is a schematic diagram of an LTE network architecture according to an embodiment of the present invention. The LTE network architecture of an embodiment of the present invention includes: one or more mobile terminals (user equipment, UE) 100, E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, evolved UMTS Terrestrial Radio Access Network) (not numbered in the figure) , Evolved Packet Cor...

Abstract

The invention discloses a data transmission system and method. The method is applied to a mobile terminal and an external device connected to the mobile terminal through USB. The mobile terminal includes a first modem connected to a physical subscriber identification card, a first temporary buffer and a second An application processor, a virtual subscriber identity card is embedded in the first modem, and the external device includes a second application processor, a second temporary buffer and a second modem; The transmission data packet is cached in the second temporary buffer for the first application processor to obtain the data packet to be transmitted from the first temporary buffer; the capacity values ​​of the first temporary buffer and the second temporary buffer are equal to the default capacity value and The sum of the increased values, and the sum of the default capacity value and the increased value is greater than or equal to the size of the data packet to be transmitted. The invention solves the problem that the mobile terminal and the external device are prone to crash during the process of transmitting telecommunication card data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data 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, Fourth-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 phone communi...
