Embodiment Construction

[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] 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.

[0049] 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 Co...

Abstract

The invention discloses a data transmission system and method. The method is applied to a mobile terminal and an external device which is connected with the mobile terminal through a preset interface. The mobile terminal comprises a first modulator-demodulator connected with a first subscriber identity module and a second subscriber identity module; and a first application processor. The external device comprises a second application processor and a second modulator-demodulator. When the second application processor entering a wakeup state from a sleep state through a handshake keyword detects a data sending instruction, the second application processor detects whether a data packet in a sending state exists in the preset interface or not; and if the data packet in the sending state does not exist in the preset interface, after first preset time, the second application processor sends a to-be-sent data packet to the first application processor in the wakeup state through the preset interface. According to the system and method, a double-LTE communication process is realized by the mobile terminal through the external device, and the accuracy of identifying the data packet by the mobile terminal is improved, wherein the data packet is sent by the external device.

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-communication, so that users can establish a data service link while realizing voice service standby. Existing mobile terminals can realize two SIM (Subscriber Identity Module, user identification card) cards to surf the Internet at the same time, but if a SIM card is connected to 4G (the 4th Generation Mobile Communication Technology, the fourth generation mobile communication technology), such as LTE (Long Term Evolution, long-term evolution technology), the other card can only connect to the 3G (3rd Generation, third-generation mobile communication technology) network or 2G (2-Generation wireless telephone technology, second-generation mobile communi...
