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 Cor...

Abstract

The invention discloses a mobile terminal and a data transmission method thereof. A first processing chip in the mobile terminal comprises a first temporary buffer and a first modulator-demodulator, a second processing chip in the mobile terminal comprises a second temporary buffer and a second modulator-demodulator, the first modulator-demodulator is connected with the second modulator-demodulator through a UART, and a capacity value of the first temporary buffer and a capacity value of the second temporary buffer synchronously change; the second modulator-demodulator caches an acquired to-be-transmitted data packet in the second temporary buffer, and therefore the first modulator-demodulator can acquire the to-be-transmitted data packet from the first temporary buffer; and the capacity value of the first temporary buffer and the capacity value of the second temporary buffer are equal to the sum of a default capacity value and an increment value, and the sum of the default capacity value and the increment value is larger than or equal to the size of the to-be-transmitted packet. According to the mobile terminal and the data transmission method, the problem that in the process that the mobile terminal achieves double-LTE communication, the mobile terminal is likely to be crashed when telecom card data is transmitted between two processing chips 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...
