The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
FIG. 1 is a flowchart illustrating a PTT set-up method according to an embodiment of the present invention. As shown in fig. 1, the PTT establishing method of this embodiment includes:
s101: when the first processor detects an interrupt event, the first processor calls an Inter-Process Communication (IPC) interrupt function, and the interrupt event is used for indicating the establishment of the PTT.
Specifically, the first processor is integrated in a System On Chip (SOC), and the SOC may also be translated into a System on Chip. The interrupt event detected by the first processor may specifically be a key interrupt of the cluster terminal where the SOC is located, where the key interrupt is used to indicate that the PTT is established. Namely, when a user needs to establish the PTT function of the cluster terminal, the user performs key operation to obtain an interrupt event of key interruption, and the first processor calls an IPC interrupt function after detecting the key interruption. Alternatively, the interrupt event may be an interrupt triggered by other sensing signals, such as a touch signal of a user clicking a touch screen, a voice control signal, a light signal, etc., and the first processor calls the IPC interrupt function after receiving the sensing signal.
S102: the first processor sends an IPC interrupt function to the second processor, the IPC interrupt function instructing the second processor to set up the PTT.
Specifically, the second processor has a function of establishing the PTT, and after the first processor calls the IPC interrupt function in S101, the IPC interrupt function is sent to the second processor, so that the first processor notifies the second processor of establishing the PTT in the form of the IPC interrupt function. The communication method between the first processor and the second processor is the same as the IPC transmission method between the processors in the SOC system, and is not limited herein.
S103: the second processor calls the MT to establish the PTT after receiving the IPC interrupt function.
Specifically, the second processor knows that the PTT needs to be established after receiving the IPC interrupt function sent by the first processor in S102. Since the MT is integrated in the second processor, the MT is a device in the PTT that is ultimately in communication with the network, which can be understood as a modem. The work of finally setting up the PTT is performed by the MT integrated inside the second processor. Therefore, the second processor directly calls the internal MT to set up PTT, and the embodiment does not limit the specific method and workflow for the MT to set up PTT.
Optionally, the second processor interrupts other events after receiving the IPC interrupt function sent by the first processor in S103, and then calls the MT to set up PTT.
The embodiment realizes the fast PTT of the cluster function through an IPC interruption mode based on the SOC. The cluster terminal needing to use the PTT function is provided with a first processor and a second processor which are integrated on an SOC, and after receiving an interrupt event for establishing the PTT sent by a user, the first processor calls an inter-core IPC interrupt function to inform the second processor to establish the PTT; meanwhile, the second processor integrates the MT for establishing the PTT, so that the second processor triggers the establishment of the PTT through the MT after receiving the IPC interrupt function sent by the first processor. The PTT establishing method provided by the embodiment has the advantages that the channel is short when the PTT is established, a special link is not required to be set to inform the MT of establishing the PTT, the PTT establishing time is shortened, and the rapid PTT is realized.
Further, in the above embodiment, the first processor in S102 calls an inter-process communication IPC interrupt function, including: the first processor calls an IPC interrupt function through an interrupt service routine.
The interrupt service program is used to detect interrupt event and call IPC interrupt function to inform MT to set up PTT, and simultaneously, the interrupt service program is also used to inform application layer TE to carry out event synchronous processing.
Further, in the above embodiment, the terminal equipment TE is integrated in the first processor.
Specifically, since the TE is integrated in the first processor, the TE within the first processor performs an event synchronization process when the first processor detects an interrupt event. Optionally, the interrupt service routine inside the first processor directly notifies the TE inside the first processor to perform the event synchronization processing.
Optionally, in the above embodiment, the IPC interrupt function has the highest interrupt priority in SOC. And when the second processor receives the IPC interrupt function sent by the first processor, the PTT establishing work is preferentially executed.
Specifically, in the above embodiment, the first server is a computer application central processing unit APP CPU of the SOC, and the second processor is a Modem central processing unit Modem CPU of the SOC.
Fig. 2 is a schematic structural diagram of a PTT set-up system according to a first embodiment of the present invention.

Specifically, the first processor 101 is integrated in a System On Chip (SOC), and the SOC may be translated into a System on Chip.

That is, when the user needs to establish the PTT function of the group terminal, the user performs a key operation to obtain an interrupt event of key interrupt, and the first processor 101 calls the IPC interrupt function after detecting the key interrupt. Alternatively, the interrupt event may be an interrupt triggered by other sensing signals, such as a touch signal of a user clicking a touch screen, a voice control signal, a light signal, etc., and the first processor 101 calls an IPC interrupt function after receiving the sensing signal. The second processor 102 has the function of establishing PTT, and after the first processor 101 calls the IPC interrupt function, the IPC interrupt function is sent to the second processor 102, so that the first processor 101 notifies the second processor 102 of establishing PTT in the manner of the IPC interrupt function. The communication method between the first processor 101 and the second processor 102 is the same as the IPC transmission method between the processors in the SOC system, and is not limited herein. The second processor 102 receives the IPC interrupt function sent by the first processor 101 and then knows that PTT needs to be established. Since the MT is integrated in the second processor 102, the MT is a device in the PTT that is ultimately communicated with the network, which can be understood as a modem. The work of finally setting up the PTT is performed by the MT integrated inside the second processor 102. Therefore, the second processor 102 directly calls the internal MT to set up PTT, and the embodiment does not limit the specific method and workflow for the MT to set up PTT.

The PTT set-up system provided by the embodiment has a short path when the PTT is set up, and does not need to set up a special link to notify the MT to set up the PTT, thereby reducing the time for setting up the PTT and realizing the rapid PTT.
Further, in the above embodiment, the first processor 101 is specifically configured to call an IPC interrupt function through an interrupt service routine.
