Dual-mode communication multifunctional mobile phone back clip

Abstract

A dual-mode communication multifunctional mobile phone back clip includes a casing, a main board, a battery, and an antenna, and is characterized in that: a dual-mode communication module is further included, the dual-mode communication module includes a system-on-chip chip, and the system-on-chip chip includes a CPU inner core, a GPU inner core, a DSP inner core, and an algorithm accelerator inner core. The functions of the private network LTE and the ad hoc network are integrated into the system-on-chip chip, wherein the functions of the private network LTE are deployed in the CPU inner coreand the algorithm accelerator inner core, and the functions of the ad hoc network are deployed in the CPU inner core and the DSP inner core. The dual-mode communication multifunctional mobile phone back clip realizes dual-mode communication in the form of back clips, so that the mobile phone back clip can realize the functions of the private network LTE and the ad hoc network without greatly increasing the volume power consumption, and greatly expands the application mode of the daily universal mobile phone under special conditions.

Description

technical field [0001] The invention belongs to the technical field of mobile phone back clips, and in particular relates to a dual-mode communication multifunctional mobile phone back clip. Background technique [0002] Mobile phones generally have public network LTE communication functions, relying on public network base stations deployed by companies such as China Mobile to achieve communication functions, but in some special applications, they need to access private network LTE. For example, the country is currently building a national digital government private network, industry private networks for electric power, circuits, public security, etc. Although these private networks all use the LTE standard, they are somewhat different from the public network in terms of frequency bands and underlying technologies. General mobile phones cannot support it. In addition, the current coverage of private network LTE base stations is limited. For example, in field expeditions, di...

Problems solved by technology

The technical problem solved by this patent is to enhance the signal of the mobile phone in the case of "lack of operator signal" and "weak or no communication signal of the mobile phone itself", so as to connect to the operator's network to realize communication with other devices, and Cannot connect to private LTE network, nor has the function of ad hoc network communication

[0005] The current dual-mode communication is realized by separating the LTE communication function and the ad hoc network communication function. For example, LTE can purchase off-the-shelf LTE modules on the market, and the ad hoc network basically uses ZigBee, WiFi frequency conversion, FPGA and DSP It is realized by a separate chip, that is to say, the ad hoc network in other products is realized outside the LTE chip, and it is possible to use a single chip that supports both LTE and ad hoc network communication systems to form a mobile phone back clip device.
