It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the invention provides a flow chart of a management method of an aerospace VOIP voice terminal;

in this embodiment, a method for managing an aerospace VOIP voice terminal includes the steps of:

s1: the voice processor receives request commands sent by all voice terminal users through the local area network communication platform, extracts address information of each voice terminal and judges the state of the voice terminal;

S2: making corresponding request feedback to the request command according to a feedback strategy corresponding to the state of the voice terminal;

in the feedback strategy, the state of the voice terminal comprises an initial state, an online state and a call state.

Specifically, in the present embodiment, the states of the voice terminal are as follows:

after the voice processor is started or reset, the voice terminal is in an initial state;

the voice processor updates the voice terminal to be in an online state after the voice terminal is normally registered, and allows to access a voice communication mode as required; the voice processor starts the voice call state after the voice terminal accesses the call.

In the present embodiment, the feedback strategy is specifically as follows:

when the voice terminal is in an initial state, the feedback strategy of the voice processor comprises the following steps: when the request command is a registration request, the voice processor adds the voice terminal into the state list, switches the voice terminal into an online state, and feeds back a registration confirmation response to the voice terminal; when the request command is a query request, the voice processor queries the current state list and feeds back the state list information to the voice terminal; when the request command is an access or exit or logout request, the voice processor feeds back an unregistered response of the voice terminal to the voice terminal.

After normal registration, each voice terminal can check the record in the state list fed back by the voice processor. The voice processor can make corresponding feedback of the updated state list according to various request commands sent by various terminals, and can check the state of each voice terminal according to the state list fed back by the voice processor.

When the voice terminal is in an online state, the feedback strategy of the voice processor comprises the following steps: when the request command is a registration request, the voice processor feeds back a registered response of the voice terminal user; when the request command is a query request, the voice processor queries the current state list and feeds back the state list information to the voice terminal; when the request command is an access request, the voice processor inquires the current terminal access quantity and then feeds back a response that the current access quantity is full or feeds back an access confirmation response to the voice terminal; when the request command is an exit request, the voice processor feeds back a response of the call which is not accessed to the voice terminal; when the request command is a logout request, after the voice processor feeds back logout confirmation, the voice terminal is switched to an initial state, the voice terminal is cleared from the state list, and the updated state list is fed back to the voice terminal.

Wherein, the feedback response of the access request of the online state further comprises: when the feedback response is the response that the access quantity is full, the voice processor feeds back the current access state list information; and when the feedback response is an access confirmation response, the voice terminal is switched into a conversation state, the access number of the voice terminal is added by 1, and the state list information is updated.

When the voice terminal is in a call state, the feedback strategy of the voice processor comprises the following steps: when the request command is a registration request, the voice processor feeds back a registered response of a terminal user to the voice terminal and switches the voice terminal into an online state; when the request command is a query request, the voice processor feeds back current state list information to the voice terminal; when the request command is an access request, the voice processor feeds back a call response accessed by the terminal user to the voice terminal; when the request command is an exit request, after the voice processor feeds back an exit confirmation, the voice terminal is switched into an online state, and an updated state list is sent to the voice terminal; when the request command is a logout request, the voice processor disconnects voice communication with the voice terminal, feeds back logout confirmation, switches the voice terminal into an initial state, removes the voice terminal from the state list, and sends the updated state list to the voice terminal.

In summary, the voice terminal obtains different feedback responses from the same request in different states. For example, in the online state, after sending the registration request, the voice processor feeds back the registered response, and in the call state, after sending the registration request, the voice processor enters the online state.

In addition, only the registered voice terminal has a record in the state list, and after the voice terminal is logged off, the voice processor removes the logged-off voice terminal from the state list.

In the embodiment, the voice processor performs corresponding feedback processing according to the request command, and the voice processor comprises a DSP chip and an ethernet transceiver.

The ethernet transceiver in this embodiment uses a KSZ8041NLJ chip. The KSZ8041NLJ chip is used as an MII/RMII physical layer transceiver, has no protocol controller, and therefore cannot be connected with a chip without an Ethernet protocol controller, such as an 8051 series or an MSP430 series. And some ARM chips, such as STM32F207, have protocol controllers inside and can be connected with KSZ8041NLJ chips.

The network layer adopts IP protocol transmission and conforms to the RFC 791 standard. The data link layer and the physical layer conform to the 100BASE-TX standard of the IEEE 802.3u specification.

Data is transmitted on the ethernet in packets, which consist of several parts, different parts performing different functions. Packets are typically generated by a network protocol program and then sent over a network transceiver onto a network cable, through the network cable to their destination machines, with the reverse process being performed at one end of the destination machines. The receiving end machine captures the packets, and performs parsing and corresponding operations.

Further, a frame, i.e., an ethernet frame, is a unit for representing a packet in a data link layer, and includes three parts: frame header, data section, frame trailer. The frame head and the frame tail comprise some necessary control information, such as a lead code, receiving end MAC address information, sending end MAC address information, Ethernet data protocol type, frame inspection sequence and the like; the data portion contains data transmitted by the network layer, such as IP packets.

The transport layer uses the UDP protocol. The UDP packet consists of a UDP packet header and UDP payload data. The UDP payload data is the application layer data.

The application layer protocol includes various management protocol fields and a status list.

The management protocol fields include status list length, identification, request/corresponding field, etc. The length of the state list is the number of network terminals accessed to the voice processor; the identifier is an application layer data packet type, for example, the data length is 8 bits, and 00(H) represents a request data packet; ff (h) indicates a response packet; the request/response field is a data request/response type, such as a data length of 8 bits, 00(H) indicates a terminal registration request, 01(H) indicates a terminal inquiry request, 02(H) indicates a terminal access request, 03(H) indicates a terminal logout request, 04(H) indicates a terminal logout request, 10(H) indicates a terminal registration confirmation response, 11(H) indicates a terminal inquiry response, 12(H) indicates a terminal access confirmation response, 13(H) indicates a terminal logout confirmation response, 14(H) indicates a terminal logout confirmation response, 15(H) indicates a response that the current access number is full, 16(H) indicates a terminal unregistered response, 17(H) indicates a user registered response, 18(H) indicates a user unaccessed call response, and 19(H) indicates a user accessed call response.

Referring to fig. 2, in the present embodiment, the first state, the second state, the third state, and the nth state represent the nth registered voice terminal state. Each voice terminal state is represented by 32 bits. Further, the whole system is in the same local area network, and records the last three bytes of the IP address, for example, 172.2.0.1 records the last three bytes 02(H)00(H)01 (H). The access state of the voice terminal is represented by 8 bits, such as 00(H) representing online; and 55(H) indicates a call state.
