To resolve the existing problem that a user terminal may merely run one RTOS based on one set of hardware resources and consequently the user terminal may merely connects to one communication network, a new solution for implementing communication is provided according to embodiments of the disclosure.

The solution according to the embodiments of the disclosure is explained in detail hereinafter in conjunction with drawings.
A method for implementing communication is provided according to an embodiment of the disclosure.
The step 21 is to determine, based on preset correspondences between respective time slices and operating systems supporting different communication network standards, an operating system corresponding to a current time slice; where the operating system supports a communication network standard.
The time slices are periods of time during which a CPU is allocated to respective processes. Usually, each process is allocated with a period of time, called as the time slice for the process, i.e., time during which running of the process is permitted. If the process is still run when the time slice expires, the access to the CPU by the process is robbed and the CPU is allocated to another process; or if the process is blocked or terminated before the end of the time slice, the CPU is immediately switched to another process. According to the embodiment of the disclosure, time division multiplexing of the CPU in a terminal by the operating systems supporting different communication network standards is implemented by setting the correspondences between the respective time slices and the operating systems supporting different communication network standards.
According to the embodiment of the disclosure, the operating systems supporting different communication network standards may include, but not limited to, an operating system supporting a communication network standard of GSM and an operating system supporting a communication network standard of TD-SCDMA.
The step 22 is to determine, based on preset correspondences between the operating systems supporting different communication network standards and memory partitions in a memory of the terminal, a memory partition corresponding to the operating system determined in the step 21.
The step 23 is to run the determined operating system based on the determined memory partition and to drive a corresponding DSP, a corresponding signal processing module supporting a communication network standard and a corresponding Radio Frequency signal transceiver based on a hardware driving program included in a system program of the determined operating system. The signal processing module being driven meets the condition of supporting the communication network standard supported by the determined operating system.
In the step 24, the signal processing module is controlled to read authentication information of the terminal from a Subscriber Identity Module (SIM) card or a Universal Subscriber Identity Module (USIM) card, the DSP is controlled to perform, based on a communication protocol corresponding to the standard supported by the determined operating system, encapsulation on the read authentication information of the terminal to generate a communication network signal.
Since the encapsulation performed on the read authentication information of the terminal by the DSP based on the communication protocol is known in the art, implementation of the encapsulation is not described here.
In the step 25, the Radio Frequency signal transceiver is controlled to convert the communication network signal into a Radio Frequency signal and send the Radio Frequency signal to the communication network.
In the method according to the embodiment of the disclosure, the correspondences between the respective time slices and the operating systems supporting different communication network standards are preset, corresponding operating systems are run in different time slices, and accordingly, the terminal is connected to different communication networks. The terminal may run a plurality of RTOSs based on one set of hardware resources, and the terminal may be connected to a plurality of communication networks.
Optionally, the method for implementing communication according to the embodiment of the disclosure may further include: driving a corresponding data buffer based on the hardware driving program. After the data buffer is driven and after the communication network signal is converted into the Radio Frequency signal by the Radio Frequency signal transceiver and the Radio Frequency signal is sent to the communication network, a storage space partition corresponding to the determined operating system is further determined based on preset correspondences between the operating systems supporting different communication network standards and storage space partitions in a storage space of the data buffer. Then the signal interacted between the terminal and the communication network may be stored in the determined storage space partition of the data buffer, and accordingly, the operating systems supporting different communication network standards may share the space resource of the buffer.
Optionally, the method for implementing communication according to the embodiment of the disclosure may further include: driving a corresponding power amplifier based on the hardware driving program. In this step, after the power amplifier is driven, if it is required to control the Radio frequency signal transceiver to convert the communication network signal into the Radio Frequency signal and send the Radio Frequency signal to the communication network, firstly, the Radio Frequency signal transceiver may be controlled to convert the communication network signal into the Radio Frequency signal; then the Radio Frequency signal is sent to the power amplifier, and the power amplifier is controlled to perform amplification and send the amplified Radio Frequency signal to the communication network.

When compared with an existing terminal, as shown in
The VMM 44 needs to perform virtualization of the CPU in the Modem 451, i.e., perform virtualization of the ARM Core 51. According to the embodiments of the disclosure, in the virtualization of the ARM Core 51, time division scheduling is performed on a hardware ability of the ARM Core 51 so that all RTOSs required to be run in parallel may share a memory, a hardware interrupt and time slices of the ARM Core 51. For example, in the terminal shown in
The VMM 44 further needs to perform virtualization of the DSP 52 as follows. In different time slices, network parameters corresponding to the different communication network standards are set for the DSP 52 based on the preset time division scheduling frequency and communication protocols run by the RTOSs supporting the different communication network standards; hence, the DSP 52 may run the communication protocols of the different communication network standards at different moments and corresponding data is encapsulated based on a currently running communication protocol. In this way, time division multiplexing of DSP 52, i.e., the virtualization of DSP 52 is implemented.
In the step 61, the ARM Core 51 determines, based on preset correspondences between respective time slices and the operating systems supporting the first or second communication network standard, an operating system corresponding to a current time slice. For example, the ARM Core 51 determines that the operating system corresponding to the current time slice is the RTOS 42.
In the step 62, the ARM Core 51 determines, based on preset correspondences between the operating systems supporting the different communication network standards and the memory partitions in the memory of the terminal, a memory partition corresponding to the RTOS 42.

In the step 64, the ARM Core 51 controls the signal processing module 54 supporting the first communication network standard to read the authentication information of the terminal from the SIM card of the terminal. The ARM Core 51 also controls the DSP 52 to perform, based on a first communication protocol corresponding to the first communication network standard supported by the RTOS 42, encapsulation on the read authentication information of the terminal to generate a first communication network signal.

In the step 66, when the above described time slice expires, the ARM Core 51 determines, based on the preset correspondences between the respective time slices and the operating systems supporting the first or second communication network standard, an operating system corresponding to a current time slice. For example, the ARM Core 51 determines that the operating system corresponding to the current time slice is the RTOS 43.
In the step 67, the ARM Core 51 determines, based on the preset correspondences between the operating systems supporting the different communication network standards and the memory partitions in the memory of the terminal, a memory partition corresponding to the RTOS 43.
In the step 68, the ARM Core 51 runs the RTOS 43 based on the memory partition determined in the step 67, and the ARM Core 51 drives the DSP 52, the signal processing module 55 supporting the second communication network standard and the second Radio Frequency signal transceiver 57 based on a hardware driving program included in a system program of the RTOS 43.
Optionally, the ARM Core 51 may further drive the second Power Amplifier 59 and/or the Data Buffer 53.
In the step 69, the ARM Core 51 controls the signal processing module 55 supporting the second communication network standard to read the authentication information of the terminal from the SIM card of the terminal. The ARM Core 51 also controls the DSP 52 to perform, based on a second communication protocol corresponding to the second communication network standard supported by the RTOS 43, encapsulation on the read authentication information of the terminal to generate a second communication network signal.
In the step 610, the ARM Core 51 controls the second Radio Frequency signal transceiver 57 to convert the second communication network signal into a second Radio Frequency signal and send the second Radio Frequency signal to the second communication network. Here the flow is ended.
Optionally, if the second Power Amplifier 59 is further driven in the step 68, after the second Radio Frequency signal transceiver 57 converts the second communication network signal into the second Radio Frequency signal, the second Radio Frequency signal may be sent to the second Power Amplifier 59 to perform amplification, then the amplified signal is sent to the second communication network.
