The method and the device can be applied to a 5G system or other wireless communication systems adopting various wireless access technologies, and can also be applied to a subsequent evolution system.

The shared processing module may mean that the communication modules share the same processing module, but the communication modules cannot share data with each other; that is, the same working mode of each communication module in the same common processing module may mean that each communication module does not need to be concurrent, and the security level between the two is the same, but the two cannot share data with each other. Furthermore, the communication modules in different common processing modules need to be concurrent or have different security levels.
The concurrency mode in the application can comprise concurrency and non-concurrency; in an operating system, concurrency may mean that several programs are running between the time when they are started and the time when they are finished, and the programs are running on the same processor, but only one program is running at any point in time.

Specifically, in the present application, the communication modules included in the common processing module do not need to be concurrent, and have the same security level, but cannot share data with each other. The communication modules of different shared processing modules need to be concurrent and have different security levels, and then each shared processing module can be controlled by adopting a switching module. Based on this application can reach integrated and keep apart the effect.
As shown in fig. 3, the number of the shared processing modules is 2, and the number of the communication modules included in the shared processing module is 2 for example; the multimode isolation integrated system can comprise two processing modules, wherein each processing module comprises two communication modules, and the multimode isolation integrated system is simply described as follows: the communication module 1 and the communication module 2 sharing the first processing module belong to the same security level (namely the same security level), are not concurrent and are isolated by partitions; the communication module 3 and the communication module 4 of the second shared processing module belong to the same security class, are not concurrent and adopt partition isolation; the group I and the group II have different security levels (i.e. different security levels), the information processing requirements of the group 2 must be independent of each other, and the group I and the group II need to be concurrent, so that the group I and the group II can be respectively controlled to achieve the physical isolation effect. Specifically, the first group and the second group can be controlled through the switching module without influencing data isolation between the first group and the second group.

the isolation processing module is used for isolating the internal network from the external network by adopting network isolation.
Specifically, the communication module in the present application may include an isolation processing module; the isolated processing module can be kept secret by network isolation. For example, two or more routable networks, such as TCP/IP (Transmission Control Protocol/Internet Protocol ), are isolated by exchanging data via corresponding protocols. The isolation processing module in the present application can be implemented by using a corresponding network isolation device or a network isolator.
In one embodiment, as shown in fig. 4, the isolation processing module may include a control circuit, and a dual port memory, a first switch, and a second switch, each connected to the control circuit;
one port of the dual-port memory is connected to an external network through a first switch, and the other port is connected to an internal network through a second switch.
Specifically, the network isolation in the present application can be implemented by using a bus-based switch. The dual-port memory in the application can mean that the same memory is provided with two groups of mutually independent read-write control lines, and the memory which works at high speed is realized due to parallel independent operation; in some embodiments, the dual port memory may be implemented using a dual port static memory.
The isolation processing module of the real-time switch based on the bus can adopt a dual-port static memory to be matched with an independent control circuit, and the dual ports are respectively connected with opposite processing units through switches (namely a first switch K1 and a second switch K2), so that the physical isolation between an internal network and an external network can be realized, and the logical connection between the internal network and the external network can be kept. The control circuit in the application can be realized by adopting an ARM. In some embodiments, as shown in fig. 4, the isolation processing module may further include switching devices (i.e., switching device 1, switching device 2).
As shown in fig. 4, the isolation processing module may provide an independent control circuit (i.e., ARM) to ensure that there is one switch on each port of the dual port static memory and that both switches cannot be closed at the same time, i.e., K1 × K2 is 0. The data exchange principle of the present application may be as follows: taking the data transmission from the external network to the internal network as an example, firstly, the external host (namely, the external network processing unit) strips the TCP/IP protocol and the application protocol from the data received by the external network, restores the data into original data, and examines the integrity and the security of the data; after the examination is passed, the secure data is transmitted to the switching equipment, then the internal host (i.e. the intranet processing unit) receives the batch of data, encapsulates the data according to the TCP/IP protocol and the application protocol, and sends the encapsulated data to the intranet, and vice versa.
The isolation processing module of the application goes through three processes of data receiving, storing and forwarding in each data exchange, and the processes are completed in the memory and the kernel, so that the speed is guaranteed, and the bus processing capacity can reach 100%.

It should be noted that the memory in the present application may include a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium.
Based on the application, the single-storage physical isolation can be divided into a public partition and a safe partition, each partition is provided with one operating system, and in operation, a user works in the environments of two mutually exclusive operating systems in a safe state and a public state, so that the isolation of an internal network and an external network is realized.

Furthermore, the switching module in the present application may be configured to control each common processing module, that is, each common processing module may be controlled by the switching module. The control process of the switching module may be triggered externally (for example, each processing module corresponds to one trigger button), and when the switching module receives a trigger signal, the switching module responds to the change trigger signal to switch to the corresponding processing module, at this time, all peripherals (i.e., external devices) are controlled by the processing module, and the processing modules outside the processing module have no influence on the communication transmission service, but need the service of the peripherals to be interrupted but not hung up, and the service can continue after the next switching back.
In one embodiment, the switching module may include a switch array;
the switch array is used for responding to the trigger signal and switching the control end of the external equipment to the corresponding processing module.
Specifically, the switch array can realize the related functions of the switching module, namely a switch array formed by a series of switches with different functions. In some embodiments, according to different peripheral signals, a switch suitable for corresponding signal characteristics is selected, and generally, a plurality of signals are provided, so that a switch array can be formed by adopting a plurality of switches.
Taking the switching module as a switch array as an example, the working process of the application is described as follows: the control of the switching module can be triggered by the outside designed as a button, each processing module can correspond to a trigger key (the serial number can be consistent with that of the communication module), when real-time service needs to be carried out by using the communication module N (N is 1, 2 and 3), the key N (N is 1, 2 and 3) is pressed, all the change-over switches are controlled by a trigger signal to be switched to the corresponding processing module N (N is 1, 2 and 3), at the moment, all the peripheral equipment is controlled by the processing module N, and the processing modules except the processing module N are not influenced by communication transmission service, but the service needing the peripheral equipment is interrupted but not hung up, and the service can continue after the next switching back.
