Digital mobile phone call waiting service refers to the service that the user can make or receive a third party call during the call, and can freely switch between two calls, which has the advantages of convenience, accuracy, accuracy and timeliness. No matter whether it is a Chinese mobile user, a Chinese telecom user, or a China Unicom user, the service can be used without an application. Call waiting must be initiated before using a multiparty call, that is, call waiting is the basis of a multiparty call. When in use, the three parties who are talking cannot hear each other at the same time. That is, when the two parties talk, the other party hears the system prompt tone. The launch of the call waiting service was originally designed by the operator for the convenience of the user. In the process of the user's call, the third party can also receive and report the third party call. The answering or hanging operation is determined by the user. However, China Telecom's CDMA network has a bug that greatly affects the user experience (BUG): Voice call service is performed on the CDMA network, and a third party call is received during the call. The called party cannot hang up the call waiting for an incoming call, and selects the hang up operation.

The embodiment of the present invention further provides a terminal, including the call waiting processing device 1 of the CDMA system according to the above embodiment. In addition, the embodiment of the present invention further provides a system. FIG. 6 is a schematic structural diagram of a call waiting processing system of a CDMA system according to an embodiment of the present invention. As shown in FIG. 6, the system includes a terminal 60 and a network side 70. The terminal 60 includes the call waiting processing device 602 of the CDMA system described in the above embodiment, and the network side 70 includes the call waiting processing device 702 of the CDMA system described in the above embodiment.

The invention will now be described in connection with preferred embodiments and preferred embodiments. FIG. 7 is a block diagram of a call waiting processing system in a CDMA network according to a preferred embodiment of the present invention. As shown in FIG. 7, the system includes: a terminal 60 and a network side 70. The terminal 60 includes an application processor 62 (Application Processor, abbreviated as AP), a framework layer 64 (Framework), a Radio Interface Layer (RIL), and a modem 68 (Modem), where AP62, Framework64, RIL66, and Modem 68 is equivalent to call waiting processing device 602 of the CDMA system of FIG. The data flow control layer of each component under the architecture, especially the components, will be described in detail below:

The AP62 is mainly implemented in the form of a Man Machine Interface (MMI) and is provided to provide an operation interface for the user. When the terminal 60 performs call waiting or call hold related processing in the three-party call, the AP 62 can obtain the link state correspondence according to the call state query, and then perform targeted processing of the call waiting of the CDMA system according to the link state correspondence.

The Framework 64 is mainly responsible for receiving and processing the request message sent by the AP 62 when the user operates the AP 62 and transparently transmits it to the RIL 66 for processing.

The RIL 66 is configured to process the request message sent by the Fram _ew0 rk64 and convert the request message into a corresponding AT command and send it to the Modem 68 for processing, where the request includes an instruction request to hang up the call waiting or an instruction request to hang up the current call. Among them, the AT command is equivalent to hanging up the extended instruction.

The Modem 68 mainly implements the 3GPP protocol support required by the terminal 60 in performing the service process, and directly interacts with the network side 70. The network 70 is mainly configured to allocate a designated link ID for the call waiting, that is, the second link or the call hold incoming call, that is, the first link, establish a correspondence between the first link and the first call state, and the second link and the first link The correspondence between the two call states, and the extension of the signaling processing for supporting the call link release for the call link ID, that is, processing the hang up extension instruction.

FIG. 8 is a flowchart of a call waiting processing method for a CDMA system according to a preferred embodiment of the present invention. The method is applied to the system architecture shown in FIG. 7. As shown in FIG. 7 and FIG. 8, the process includes the following steps: Step S802 The modem of the terminal receives the call waiting incoming call message reported by the network side. After the modem receives the call waiting incoming call message reported by the network side, the terminal triggers a call state change message, sends a call state query command to the network side, and obtains a link state correspondence relationship from the network side, for example, a second chain corresponding to the call waiting message. Link ID of the road and its corresponding second call state, and/or corresponding voice call The link ID of the first link and its corresponding first call state. At the same time, the user's operation is detected. If the user clicks the hang up request, step S804 is performed, otherwise step S806 is performed. Step S804, sending an hang up extension command according to the ID of the call waiting incoming call, instructing the network side to hang up the call waiting for the incoming call.

After the AP detects that the user hangs up the call and waits for the incoming call, that is, the command to disconnect the second link, the hang up message is sent to the frame for the ID of the call waiting for the call, that is, the link ID of the second link, and the framework hangs up. The message is transparently transmitted to the RIL, and the RIL converts the hangup message into a corresponding extended AT command and sends it to the Modem, and the Modem performs corresponding signaling interaction processing with the network. Among them, the extended AT command is equivalent to hanging up the extended instruction. Step S806, sending an hang up extension command according to the link ID of the current call, instructing the network side to hang up the current call. In the case that the user chooses to answer the call and wait for the incoming call, the original call state is changed to call hold, and the call waiting call is changed to the call state. If the click button is clicked again, the call in the current call is triggered to hang up and the call is automatically held. The call is switched to the call state.

9 is a flow chart of a second method for call waiting processing of a CDMA system according to a preferred embodiment of the present invention, as shown in FIG.

As shown in FIG. 9, the process includes the following steps: Step S902: The terminal establishes a voice call by calling or called. Take the calling number 10000 as an example. After the call is made, the call status query command "AT+CLCC" is used to query the current call status. The returned results are as follows: > AT+CLCC

< +CLCC: 1 (idl), 0 (MO), 0 (active), 0 (voice), 0 (non-multiparty call), 10000 (call number), 129 (number type), 255 (alpha string), 255 (priority)

<OK Step S904, after receiving the call waiting message reported by the network side, initiate a call state query instruction. At this time, another voice call is received, and the network side reports the call waiting message to the terminal. In the related art, the call waiting message is as follows: < +CCWA: +85226773333 (caller number), 145 (num type), 1 (class, the call is a voice call). It can be seen from the content actively reported by the network side that the call waiting message does not include the link ID information. At this time, the terminal sends a call status query command, and the return result is consistent with the call waiting for the call. The call status query command does not return the status information of the call waiting call, and the terminal cannot hang up the call waiting for the call. In this embodiment, before the network side reports the call waiting message, the network first assigns the link ID1 to the first link that has established the voice call, and assigns the link ID2 to the call waiting for the second link, and links the link. The ID corresponds to the call state information, so as to ensure that the state information of the corresponding link can be queried according to the link ID. In this embodiment, after receiving the call waiting message reported by the network side, the terminal sends a call state query command to the network side, and obtains a result returned by the network side, where the result returned by the network side is equivalent to the link state correspondence relationship. The process of obtaining the link state correspondence is as follows:

> AT+CLCC

< +CLCC: 1 (idl), 0 (MO), 0 (active), 0 (voice call), 0 (non-multiparty call), 10000 (call number), 129 (number type), 255 (alpha string), 255 (priority)

<+CLCC: 2 (id2), 1 (MT), 5 (call waiting), 0 (voice call), 0 (non-multiparty call), "+85226773333" (caller number), 145 (number type), 255 ( Alpha string), 255 (priority)

< OK As can be seen from the above, all the voice call states currently existing on the terminal are very clear, and the correspondence between them and the link is also very clear. The network side may carry a link state correspondence relationship when the base station sends a channel assignment message to the terminal. As shown in FIG. 10, the channel dominance message is equivalent to the return result of the call state. Step S906, detecting the operation of the user, and performing corresponding call waiting processing according to the operation of the user. The terminal receives the call waiting for incoming call during the call. At this time, if it is detected that the user clicks the hang up button, it is equivalent to the instruction to disconnect the second link, and the terminal sends the hang up extension command AT^CHLD=0, and gives the calling party. The voice prompt that the user dialed is busy. In the related art, at this time, the terminal delivers the call hangup command AT+CHV, and thus cannot indicate which link to hang up. If it is detected that the user clicks the answer button, which is equivalent to the command to turn on the second link, the terminal sends an instruction AT+CFSH to turn on the second link, and the call of the first link that is already in the connected state is maintained. The call waiting for the call, that is, the second link becomes the call state, that is, the terminal has two calls, and all the way is activated all the way, and the state of the two-way call can be switched by issuing the command switching command AT+CFSH. At this time, if it is detected that the user clicks the hang up button, the terminal issues an hang up extension command AT^CHLD=1, instructing the network to hang up the current voice call and activate the held voice call. In the related art, the AT+CHV command is sent by the terminal to perform the hang-up action. As a result, the activated and held calls are hanged at the same time, and the user experience is poor. The hangup extension instruction carries a corresponding link state correspondence.

11 is a flow chart of a third method of call processing for a CDMA system according to a preferred embodiment of the present invention, as shown in FIG.

As shown in Figure 11, the process includes the following steps: Step S1102: The terminal establishes a voice call. The voice call corresponds to the first link. Step S1104: The terminal receives a voice call. The voice call is equivalent to a call waiting call corresponding to the call waiting message, which corresponds to the second link. After receiving the voice call, the terminal acquires the link state correspondence from the network side, that is, the first link ID and the first call state corresponding thereto, and/or the second link ID and the second call state corresponding thereto. Step S1106: Detect whether the user selects to answer. If it is detected that the user chooses to answer the voice call, step S1108 is performed, otherwise step S1114 is performed. Step S1108, sending an hang up extension instruction. The terminal sends a hangup extension command AT^CHLD=0 to the network side, where the command carries the link state correspondence relationship obtained by the terminal from the network side. In step S1110, it is determined whether the execution is successful. The terminal determines whether the hang up is successful. If successful, step S1112 is performed. Otherwise, step S1108 is performed. In step S1112, the network side hangs up the call and waits for an incoming call. End this process. In step S1114, a turn-on command is sent. The terminal sends an instruction AT+CFSH to the network side to switch on the second link. In step S1116, the terminal has two calls. The network side connects the second link to the terminal. At this time, the terminal has two calls, one corresponding to the first link, which is in the hold state, and one way corresponding to the second link, which is in an active state. In step S1118, it is detected that the user clicks to hang up. Equivalent to receiving an instruction from the user to hang up the current call. In step S1120, the terminal sends an hang up extension command. The terminal sends an extension command AT^CHLD=1, which instructs the network to hang up the current voice call and activate the voice call in the hold state. In step S1122, it is determined whether the execution is successful. It is judged whether the hang up is successful, if the execution is successful, step S1124 is performed, otherwise, step S1120 is performed. Step S1124, disconnect the current call, and answer the hold call. From the above description, it can be seen that the following technical effects are achieved in the embodiment of the present invention: the terminal receives a call waiting call during a call, and the network side allocates a call ID to the call waiting call, so as to implement the call state and the ID number, After the call status query is available, the terminal generates an hang up extension command according to the link state correspondence, and sends the hang up extension command to the network, and the network receives the hang up extension signaling and executes the corresponding request to implement the function optimization of the three-party call.
