Description

Method for realizing multi-party call and call terminal
Technical Field
The present invention relates to the field of applications of wireless communication terminals, and in particular, to a method for implementing a multi-party call and a call terminal.
Background
With the continuous development of communication technology, multiparty calls and telephone conferences begin to prevail, and in the prior art, a single channel is mostly used for realizing the dialing of multiple paths of telephones. In the process of realizing the dialing of a multi-path telephone by using a single channel, after a protocol stack receives the final state of the Call of a network side, the final state is coded, an AT command is generated and reported to a Call management service layer, after the Call management service layer receives the command, the Call management service layer inquires the Call channel number (CID) of a mobile phone corresponding to the incoming Call, then the corresponding telephone number is matched, and finally the CID and the telephone number are reported to a man-machine interface; however, the process of querying and matching can increase the time to call. In addition, each large manufacturer expands the intermediate state by itself, and reports the CID through the intermediate state, wherein the intermediate state includes a ringing message received in the calling process, a call connection establishment message received in the called process, and the like; in addition, in the process of multi-party call, if the intermediate state of one call is mixed with the intermediate state of another call, the call state is disordered.
In the prior art, there is also a situation that the actual response result and operation are inconsistent when a multi-party call is performed, for example, a second way of call is dialed when a first way of call is already connected, and if the called party of the second way of call refuses at this time, the called party of the first way of call hangs up, so that two final result codes are reported at the same time, and therefore, which of the final result codes corresponds to which of the calls is not determined, which leads to a disordered call state; for the problem, some manufacturers propose a solution, that is, the default final result code received first is for the second call, and the final result code received later is for the first call; however, with this solution, there are three cases in the process of implementing a multi-party call: first, the first call is hung up, but the received call is considered to be the final result code of the second call; secondly, the time difference of hanging up the two paths of calls is very small, and the network side does not necessarily report the final result code of the second path of calls first; thirdly, even if the second-path call is refused, the first-path call is hung up, and under the actual condition, the second-path call state refused is a busy state, so that the reporting speed of the final result code of the second-path call is relatively slow, the final result code of the first-path call can be reported only after several seconds, and the final result code of the first-path call can be reported, so that the state reporting is disordered.

The invention provides a method for realizing multi-party call, fig. 2 is a flow diagram of the method for realizing multi-party call, as shown in fig. 2, the method comprises the following steps:
step 201, a call management service layer of a call terminal initiating a call or actively hanging up receives a request message;
specifically, when a user of a calling call terminal picks up a phone and inputs the number of a called call terminal and presses a call key, or when the user on any side hangs up a call and presses a hang-up key, a call control module of a call management service layer of the call terminal which initiates a call or actively hangs up receives a request message; when a calling call terminal user picks up a phone and inputs the number of a called call terminal and presses a call key, a request message received by a call control module is a call request message; when a user on any side hangs up a call, the request message received by the call control module is a hang up request message;
after receiving the request message, a call control module of the call management service layer queries the current call state of the call in which the call terminal sending the request message is located through an interface provided by the management module, the call control module judges whether the queried current call state is correct, if so, step 202 is executed, and if not, the step is ended; for example, when the user hangs up the second-path call, the call control module determines whether the current call state of the second-path call with CID 2 is correct, if the current call state is activated, hung up, calling, call waiting, the current call state is correct, and if the current call state is no call, the current call state is wrong;
step 202, the call management service layer generates an AT command according to the request message and sends the AT command to a protocol stack of the communication terminal where the call management service layer is located;
specifically, a call control module of a call management service layer forwards a request message to a coding module of the call management service layer, and the coding module codes the received request message to generate an AT command; if the request message is a call request message, the message carries the number of the called call terminal; if the request message is a hang-up request message, the message carries the CID of one path of call needing to be hung up; the coding module codes according to the number of the called call terminal in the request message or the CID of one call needing hanging up; the coding method is that according to the character string format of the AT command, the content of the request message which needs to be coded is filled into the character string of the AT command; for example, the string of AT commands may be: ATD [ < n > ] [; < n > ] is the number and the decoration symbol of the called talking terminal, or CID and the decoration symbol; the coding module sends the generated AT command to an analysis module of a protocol stack of the self-located call terminal, namely, the analysis module of the protocol stack of the call terminal which initiates a call or actively hangs up. Here, since the interaction between the protocol stack of the call terminal and the call management service layer can only use the AT command, the request message needs to be encoded into the AT command before being sent to the protocol stack.
Step 203, the protocol stack analyzes the AT command, interacts with the network side according to the content of the request message obtained by analysis, and obtains the final result of the call with the called call terminal or the passive hang-up call terminal and the CID corresponding to the call;
specifically, an analysis module of a protocol stack of a call terminal initiating a call or actively hanging up analyzes a received AT command, and the analysis method is to extract the content of a request message from a character string of the AT command according to the character string format of the AT command; the analysis module sends the extracted content of the request message to an interaction module of a protocol stack, and the interaction module interacts with a network side according to the content of the request message to acquire a final result of the call of the called call terminal or the passive hang-up call terminal and a CID corresponding to the call;
for example, after the analysis module analyzes the AT command, if the number of the called call terminal is obtained, the number is sent to the interaction module, after the interaction module receives the number of the called call terminal, the interaction module knows that calling needs to be performed according to the number, the called call terminal is called through the network side, the interaction module obtains the final result of calling the called call terminal and the CID corresponding to the call through the network side, and the final result and the CID are sent to the extension coding module of the protocol stack; the final calling result comprises NO CARRIER, NOANSWER, BUSY and OK, wherein NO CARRIER indicates that the connection of the calling link fails, NO ANSWER indicates that the calling communication terminal successfully calls but the called communication terminal does not respond, BUSY indicates that the calling communication terminal successfully calls but the called communication terminal refuses, and OK indicates that the calling communication terminal successfully calls and the called communication terminal ANSWERs;
after the AT command is analyzed by the analysis module, if the obtained CID of the call needing to be hung up is sent to the interaction module, after the interaction module receives the CID of the call needing to be hung up, the interaction module knows that the call corresponding to the CID needs to be hung up according to the CID, the interaction module informs the passively hung up call terminal relative to the actively hung up call terminal to hang up the call through the network side, acquires the final result of hanging up and the CID corresponding to the call through the network side, and sends the final result and the CID to an extended coding module of a protocol stack of the actively hung up call terminal; the final result of hang-up includes OK or ERROR, OK represents that the passively hung-up call terminal is hung up successfully, and ERROR represents that hang-up fails due to network or unknown problems.
Step 204, a protocol stack of the call terminal initiating the call or actively hanging up generates an expanded AT command according to the obtained final result and the CID, and sends the expanded AT command to a call management service layer of the call terminal where the protocol stack is located;
specifically, an extended coding module of a protocol stack of a calling or active hanging-up call terminal codes a received final result and a CID obtained by an interactive module, and the coding method is that according to a character string format of an AT command, the content of the final result needing to be coded is filled in a character string of the AT command, and then the CID is added into the character string of the AT command to finally obtain an extended AT command; for example, the string format of the extended AT command may be + XCPI: 1/r/nNO CARRIER, wherein 1 is CID and represents the first call, and NO CARRIER represents the final result of the first call; and the extension coding module of the protocol stack sends the generated extension AT command to an analysis module of a call control service layer of the call terminal which initiates a call or actively hangs up.
Step 205, the call management service layer analyzes the extended AT command, manages the CID and the final result obtained after the analysis, and performs call control according to the CID and the final result;
specifically, an analysis module of a call control service layer of a call terminal initiating a call or actively hanging up analyzes a received extended AT command to obtain a CID and a final result, and simultaneously sends the CID and the final result to a management module and a call control module of the call control service layer; the management module is used for storing CIDs of all calls and current call states corresponding to the CIDs, finding the current call states corresponding to the CIDs according to the CIDs and updating the current call states according to final results;
the call control module can obtain a path of call needing call control according to the CID, and performs call control on the path of call according to a final result, wherein the call control comprises opening a call channel, cutting off the call channel and the like; meanwhile, the call control module needs to prompt the user of the execution result of the call control; for example, by popping up a box, the box may display "being connected", "ending call", and the like, and may also display the call duration and the like at the same time.
By using the method of this embodiment, the call terminal 1 is called and connects one path of call, then dials the second path of call, the called refuses, AT this time, the final result BUSY reported by the network side is slow, the call terminal 1 does not receive the final result temporarily, AT this time, the user of the call terminal 1 hangs up the first path of call, the call control service layer of the call terminal 1 can receive the extended AT command, wherein the extended AT command carries the message that the final results NO CARRIER and CID are 1, and therefore the call terminal cannot be mistakenly regarded as the final result of the second path of call.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements, etc. that are within the spirit and principle of the present invention should be included in the present invention.
