Problems solved by technology
[0002] When public safety occurs, such as earthquakes, fires and other emergencies, the cellular network is usually affected. For example, when the signal is unstable, or even when there is no signal, the cellular network will be affected and cannot work normally.
At this time, users cannot use mobile terminals, such as mobile phones, to communicate, which delays the time and information communication of disaster relief and mitigation, and makes disasters worse

Embodiment Construction
[0020] see figure 1 , figure 1 It is a mobile terminal that can perform end-to-end communication under off-network conditions provided by the embodiment of the present invention. The mobile terminal 10 includes a first transceiver module 11, a second transceiver module 12, a setting module 13 and a switch membrane block 14.
[0021] Wherein, the first transceiver module 11 performs signal reception on the first frequency and transmits signals on the second frequency, and the second transceiver module 12 performs signal transmission on the first frequency and performs signal reception on the second frequency. It can be seen that the frequencies used by the first transceiver module 11 and the second transceiver module 12 for signal transmission and reception are paired frequencies. Specifically, the frequency for signal reception by the first transceiver module 11 corresponds to the second transceiver module 11. The frequency at which the module 12 performs signal transmission...

The invention discloses a mobile terminal and method capable of performing end-to-end communication under an offline condition. The mobile terminal comprises a first receiving-transmitting module, a second receiving-transmitting module, a setting module and a switching module, wherein the first receiving-transmitting module is used for performing signal reception at a first frequency and performing signal transmission at a second frequency; the second receiving-transmitting module is used for performing signal transmission at the first frequency and performing signal reception at the second frequency; the setting module is used for receiving the working mode of the mobile terminal selected by a user; and the setting module is used for selecting the first receiving-transmitting module to perform signal receiving-transmitting work through the switching module when an online mode selected by the user is received, and for selecting the second receiving-transmitting module to perform signal receiving-transmitting work through the switching module after an offline mode selected by the user is received in order that the mobile terminal can perform end-to-end communication with other mobile terminals while working in the offline mode. The mobile terminal can work under the offline condition, so that network constraints are avoided.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a method capable of performing end-to-end communication under off-network conditions. Background technique [0002] When public safety occurs, such as earthquakes, fires and other emergencies, the cellular network is usually affected. For example, when the signal is unstable, or even when there is no signal, the cellular network will be affected and cannot work normally. At this time, users cannot use mobile terminals, such as mobile phones, to communicate, which delays the time and information communication of disaster relief and mitigation, and makes disasters worse. [0003] Therefore, it is necessary to provide a technical solution to solve the above technical problems. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a mobile terminal and a method capable of end-to-end communication ...
