[0005] In an exemplary embodiment, after dynamically allocating the antenna time slot occupied by each communication system according to the amount of data transmitted by the communication system, the method further includes: switching between the multiple communication systems according to the allocated antenna time slots.

[0006] In an exemplary embodiment, the clock synchronization of multiple communication systems of the same terminal includes one of the following: clock synchronization of the multiple communication systems through clock synchronization functions of the multiple communication systems; setting a common clock for the multiple communication systems.

[0007] In an exemplary embodiment, the dynamic allocation of antenna time slots occupied by each communication system according to the amount of data transmitted by the communication system includes: obtaining the amount of data transmitted by each communication system within a preset time interval and comparing them; and dynamically allocating the antenna time slots occupied by each communication system according to the comparison results.

[0008] In an exemplary embodiment, the antenna shared by the multiple communication systems includes a main antenna and an auxiliary antenna, and the main antenna and the auxiliary antenna respectively use independent switching switches to implement different working modes of the multiple communication systems.

[0009] In an exemplary embodiment, the working mode includes one of the following: only one communication system is online, and the online communication system works independently; multiple communication systems are online, and each online communication system works independently through network fallback; multiple communication systems are online, each online communication system completes clock synchronization, and multiple communication systems are time-division multiplexed through the RF front end.

[0039] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as a read-only memory / random access memory (ROM / RAM), a disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present application.

[0045] In order to facilitate the understanding of the technical solutions provided by the application embodiments, the embodiments are described below in combination with specific scenarios.

[0046] Figure 5 is a flowchart of a method for processing coexistence of multiple communication systems according to another embodiment of the present application, such as Figure 5 As shown, the method comprises the following steps:

[0047] Step S502, aligning the timing of different communication systems;

[0048] Specifically, since modern broadband and narrowband communication systems operate at high frequencies, usually in the range of 300MHz-6000MHz, and the time interval of communication subcarriers is usually at the level of us (microseconds)-ms (milliseconds), in order to achieve fast switching of different communication systems, a high-precision clock reference circuit is required, and the clock synchronization function of different communication systems is used to synchronize the clocks of two or more communication systems, or a common clock solution is used to achieve clock synchronization;

[0049] Step S504, distinguishing time slot intervals of different communication systems.

[0050] Specifically, by analyzing and sorting out the working timings between the communication protocols of various communication networks, the time intervals of two or more communication systems are distinguished by a data model, and the switching of multi-system shared antennas is achieved through time division between two different communication systems.

[0051] Figure 6 is a schematic block diagram of the connection of the main and auxiliary antennas of the two-way communication system working in the intelligent time division multiplexing mode according to an embodiment of the present application, such as Figure 6As shown, two main and auxiliary antenna interfaces of two different Long Term Evolution (LTE) communication systems are respectively connected to a single-pole double-throw switch (SP2T), connected to a double-pole double-throw (DPDT) through the single-channel interface of the SP2T, and then connected to the two antennas through the interfaces on both sides of the DPDT.

[0052] Figure 6 In the intelligent mode shown, the system side completes the subframe synchronization (clock synchronization) of system A and system B, and uses time division multiplexing through the RF front end to prevent the user layer from sensing the system disconnection. The terminal dynamically allocates the antenna occupancy time in real time according to the data carrying capacity of each network.

[0053] Figure 7 is a schematic block diagram of the connection of the main and auxiliary antennas of the two-way communication system working in independent mode according to an embodiment of the present application, such as Figure 7 As shown, when only system A or only system B is online, the working diagram shows that the single system is in the optimal state of system performance, in conventional terminal mode.

Figure 8 As shown, system A and system B are online at the same time, and the two systems work independently. The system end turns off Multiple-Input Multiple-Output (MIMO) and the network side falls back to Telemanagement 1 (TM1) mode to ensure that each system can maintain a normal single-antenna connection.

[0055] From the above description, it can be seen that the above embodiment achieves the following technical effects: through lower design and manufacturing costs, it is relatively easy to achieve a more flexible terminal structure. It has low requirements on system integration capabilities and is compatible with normal mode, single-channel mode, and smart mode.
