Technical Field

Background

POC is an abbreviation of Push to Talk over Cellular, and refers to a half-duplex voice service implemented by using VoIP technology based on a mobile Cellular network packet domain bearer, and can support rich talkback applications such as one-to-one session, one-to-many group session, full call, and strong insertion. A "one-to-one" or "one-to-many" call can be conducted quickly, just as with a walkie-talkie. Because the cellular communication system is based on a mature operator, cross-regional calling can be conveniently realized. This feature is suitable for small and medium-sized businesses that require frequent intermediate contacts and for individual users who need to chat with friends and family. The method is widely applied to logistics, motorcade, port, city management and other industries at present.

POC communication, as a fast communication method between one-to-one or groups, enables a terminal device to be utilized like a radio transceiver. Communication between groups is performed using SIP (RFC 3216) which is a network protocol, and a network of mobile phones is used. However, the existing POC communication is performed by using the above network protocol, which has the advantages of low cost, good applicability and good expansibility, but since the public network talkback service is complex and there are many signaling and voice interactions with the platform, developers who need to develop talkback applications need strong expertise, which results in slow popularization.

Example 1

As shown in fig. 1, the present embodiment provides a method for controlling a POC communication module using an AT command, where the method is used for calling the POC communication module to perform a trunking communication for a POC-related application unit of a user equipment; the method comprises the following steps:

s1: reading request AT instructions sent by all application units from a user terminal, primarily screening the read request AT instructions, and eliminating invalid request AT instructions;

s2: sequencing the request AT instructions after the preliminary screening is finished to obtain a request instruction queue to be sent, and confirming the current request AT instructions from the request instruction queue;

s3: acquiring an application unit corresponding to a current request AT instruction, and sending the request AT instruction corresponding to the application to a POC communication module through the application unit;

s4: receiving an AT request instruction by the POC communication module, judging whether the POC communication module is in a response state, and executing synchronous response operation if the POC communication module immediately responds; when the timeout does not respond, executing asynchronous response operation;

s5: the POC communication module returns the AT command to the corresponding application unit to complete the execution of the current AT command request, returns to the AT command request queue in step S3, and sends the next AT command request in the AT command request queue to the POC communication module.

In this embodiment, the request AT command consists of a command header, a length and a carrying content. The format is as follows:

command head

Length (length of carrying content)

Carrying content

The command header is a fixed character string, and the length is 1 byte occupied by hexadecimal number, which is the length of a character string carrying content. The portable content adopts standard ASCII code characters, all numbers contained in the portable content adopt decimal representation, and a plurality of parameters contained in the portable content adopt character separation.

In this embodiment, the return AT command consists of a command header and a result, and may also consist of a command header, a result and contents. The return AT instruction may carry a result field as a result of the response to indicate whether the command is successfully executed, and may also carry response content, and whether the return AT instruction contains content is an optional item to indicate an effect after the simple synchronization command is executed. The format of the return AT command is as follows:

command head

Results

Contents (optional)

The command header of the return AT command is the same as the command header of the corresponding request AT command, the command header is a fixed character string, the content of the return AT command is the same as the content carried by the corresponding request AT command, and the command header, the content and the result are separated by commas.

In S1 of the present embodiment, please refer to fig. 2, the method for reading the AT request instruction for preliminary screening includes:

s11, sequentially judging whether the read request AT instructions are repeated with the previous request AT instructions, if so, eliminating the redundant request AT instructions, otherwise, reserving the request AT instructions;

s12, sequentially judging whether the logic of the command format corresponding to each read request AT instruction accords with the specification, if so, reserving the effective request AT instruction, otherwise, judging the request AT instruction as an invalid request AT instruction and rejecting the invalid request AT instruction.

After all the read request AT instructions are preliminarily screened, repeated items and invalid instructions which do not conform to the format of the request AT instructions can be removed, the validity of each request AT instruction is ensured, so that the execution efficiency is improved when POC communication is carried out, and the problems of request AT instruction backlog or communication connection overtime caused by the fact that no response can be obtained due to the fact that the invalid request AT instructions are sent are avoided.

In this embodiment, referring to fig. 3, in S2, the method for confirming the current AT request instruction from the AT request instruction queue includes:

s21, reading all the effective request AT instructions reserved after the preliminary screening, and sequencing according to the sequence of the reading time to obtain a request instruction queue to be sent;

and S22, taking the head item of the request instruction queue as the current request AT instruction.

The operation can not only sort the screened effective request AT commands, but also execute the request sending operation from the first request AT command, so that the POC communication is carried out orderly.

In this embodiment, in S4, when determining whether the POC communication module is responding to a timeout, the POC communication module determines according to a timeout mechanism, and in this embodiment, taking the timeout time as 3S as an example, when the POC communication module responds within 3S, a synchronous response operation is performed, and when the POC communication module does not respond after exceeding 3S, an asynchronous response operation is performed.

When synchronous response operation is executed, the POC communication module immediately sends an execution result back to the application unit through the return AT command after receiving the response of the current request AT command sent by the application unit, and the execution of the current request AT command is completed.

When asynchronous response operation is executed, when the POC communication module responds to the received current request AT command sent by the application unit, processing is started, and the execution result is sent back to the application unit through the return AT command, so that the execution of the current request AT command is completed.

Reporting the response result to the application unit in the unresponsive time period before executing the asynchronous response, that is, the response result is not responded after exceeding 3S, and reporting the response result to the application unit in the first time while judging that the asynchronous response operation is executed after exceeding 3S, but the application unit does not need to wait for the POC communication module to send back the AT request, and directly returns to S3, and sends the next AT request command in the request command queue to the POC communication module. The communication connection time can be greatly shortened, and the next POC communication operation can be started in advance.

The method for controlling the POC communication module using the AT command in this embodiment may be designed as an application software, such as a communication system, and further loads the communication system into the terminal device to implement corresponding trunking communication.
