Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] 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.

[0039] 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 Core...

Abstract

The invention discloses a mobile terminal and a data transmission method. A first processing chip in the mobile terminal comprises a first temporary buffer area and a first modem, a second processing chip comprises a second temporary buffer area and a second modem, the first modem is connected with the second modem through a UART, and capacity values of the first temporary buffer area and the second temporary buffer area synchronously change; the second modem caches an obtained to-be-transmitted data packet in the second temporary buffer area, so that the first modem obtains the to-be-transmitted data packet from the first temporary buffer area; and the capacity values of the first temporary buffer area and the second temporary buffer area are equal to a sum of a default capacity value and an increased value, and the sum of the default capacity value and the increased value is greater than or equal to the magnitude of the to-be-transmitted data packet. When the mobile terminal realizes double LTE communication, and when telecom card data are transmitted between the two processing chips, the problem that the mobile terminal is prone to crash is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a data transmission method thereof. 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 ph...
