Detailed Description
However, in the prior art, the calling device needs to know whether the called device can be called after the call is initiated, and the calling device cannot know whether the called device is convenient to talk currently. For example, the called device is currently in a teleconference state, and is inconvenient to answer a call. However, the calling device is not aware that the called device is currently in a teleconference state. If the calling device initiates a call, the called user corresponding to the called device may refuse to receive the call.
In the embodiment of the invention, after receiving the call request, the current equipment state information of the user is acquired, and the current equipment state information of the user is sent. The calling device can acquire the current device state information of the called device, and then the calling user determines whether to continue to call the called device, so that the calling device can be ensured to establish high-quality call with the called device in some special application scenes, and the user experience is improved.
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a call control method, and the call control method is described in detail through specific steps with reference to fig. 1.
In the embodiment of the present invention, the call control method provided in the following steps S101 to S102 may be executed by the called device. Specifically, the following steps S101 to S102 may be performed by a baseband chip in the called device or a chip module including the baseband chip in the called device.
Step S101, receiving a call request and acquiring current equipment state information of the call request.
In a specific implementation, the calling device and the called device may implement a call based on IMS VoLTE functionality. When the calling device has the requirement of calling the called device, the calling user corresponding to the calling device can input the telephone number corresponding to the called device on the dialing interface corresponding to the calling device and call out. When the calling device calls out the telephone number of the called device, the calling device may output a call request (INVITE) to the network side. After receiving the call request output by the calling device, the network side can forward the call request to the called device.
In the embodiment of the invention, the called equipment can acquire the current equipment state information after receiving the call request. The current device state information of the called device may be used to characterize whether the called device is able to establish a call with the calling device and/or to characterize whether the called device is able to establish a high quality call with the calling device.
In the embodiment of the invention, the current equipment state information of the called equipment can only comprise any one of the current use state information of the called equipment, the current electric quantity information of the called equipment, the current signal quality information of the called equipment and the current environment information of the called equipment, or a plurality of the current use state information of the called equipment, the current electric quantity information of the called equipment, the current signal quality information of the called equipment and the current environment information of the called equipment.
In a specific application, if the current usage status information of the called device is that a call is made with other user devices, the called device may not be able to establish a call with the calling device currently or may not be able to establish a high quality call with the calling device. If the current use state information of the called equipment is in a shutdown state, the called equipment cannot establish a call with the calling equipment currently.
If the current use state information of the called equipment is: when the device is in a remote conference state, the called device may be in an important occasion at present, and the call is inconvenient to be received, so that the call of the calling device may be refused to be received. If the current use state information of the called equipment is: when the navigation state is started, the user corresponding to the called equipment may be in a driving state at present, and the call is inconvenient to answer, so that the call of the calling equipment may be refused to answer.
If the current electric quantity of the called equipment is low, the called equipment can not establish a call with the calling equipment at present; alternatively, even if the called device is able to establish a call with the calling device, the power of the called device may not be able to complete the long duration call because the calling device may need to make a longer time consuming call with the called device.
If the current signal quality of the called equipment is poor, the called equipment may not be capable of establishing a call with the calling equipment at present; or even if the called equipment can establish a call with the calling equipment, the situation of call interruption in the process of communicating with the calling equipment may be caused due to poor signal quality of the called equipment, so that the call quality is lower.
If the called equipment is currently in downtown area, the surrounding environment is noisy, and the noise in the background sound of the called equipment is larger. Even if a connection is established with the calling device, the call quality is low due to the large background noise.
It can be seen that the current device state information of the called device is related to whether the called device can establish a call connection with the calling device, and/or is related to whether the called device can establish a high-quality call connection with the calling device. In other words, the current equipment state information of the called equipment relates to whether the call between the called equipment and the calling equipment is established or not and the call quality is high or low.
It will be appreciated that, in a specific application, the current device state information of the called device may further include other information corresponding to the called device, where the other information corresponding to the called device may be used to characterize whether the called device can establish a call with the calling device, and/or to characterize whether the called device can establish a high quality call with the calling device.
Step S102, the equipment state information is sent.
In a specific implementation, after the called device obtains the current device state information of the called device, the current device state information of the called device can be sent.
Referring to fig. 2, a schematic diagram of signaling interaction based on VoLTE call session initiation protocol (session initiation protocol, SIP) is shown.
The calling device may generate a call request (INVITE) to send to the network side when initiating a call. The network side may send a call request (INVITE) to the called device. The called device may send 183Session progress signaling to the network side after receiving the call request (INVITE). The network side may send a 183Session progress signaling to the calling device. 183Session progress signalling is signalling in the resource reservation medium negotiation process.
After receiving the 183Session progress signaling, the calling device may generate a PRACK signaling and send the PRACK signaling to the network side. And the network sends the PRACK signaling to the called equipment. After receiving the PRACK signaling, the called equipment generates a 200OK signaling and sends the 200OK signaling to the network side, and the network side sends the 200OK signaling to the calling equipment.
After the calling device receives the 200OK signaling for the first time, the calling device generates UPDATA signaling and sends the UPDATA signaling to the network side, and the network side forwards the UPDATA signaling to the called device. After receiving the UPDATA signaling, the called device generates a 200OK signaling for the second time and forwards the 200OK signaling to the calling device through the network side. After the called equipment sends the 200OK signaling for the second time, 180RINGING signaling is generated and sent from the network side. The network sends 180RINGING signaling to the calling device. After sending 180RINGING signaling, the called device sends 200OK (INVITE) signaling to the network side. The network side forwards the 200OK (INVITE) signaling to the originating device.
In a specific application, the procedure based on the VoLTE call SIP signaling interaction described in fig. 2 may refer to an existing protocol, where a specific data interaction procedure is not described in detail in the embodiment of the present invention. Based on the existing protocols, those skilled in the art will know that 180RINGING signaling is RINGING signaling, meaning that the called device rings.
In a specific implementation, the called device may send its current device state information to the network side before sending the RINGING notification (i.e., 180RINGING signaling). After receiving the current equipment state information of the called equipment, the network side can forward the equipment state information of the called equipment to the calling equipment, so that the calling equipment can acquire the equipment state information of the called equipment.
In the embodiment of the invention, the called equipment can transmit the current equipment state information of the called equipment through a new signaling. The called device may send the new signaling from the network side, which sends the new signaling to the calling device. After receiving the new signaling, the calling device can acquire the device state information of the called device.
In the embodiment of the invention, the called equipment can also transmit the current equipment state information of the called equipment through the existing signaling. As can be seen from fig. 2, before the called device sends the ringing notification, the called device sends 183Session progress signaling and 200OK signaling twice to the network side. The called device can transmit its current device state information through the 183Session progress signaling bearer, and can also transmit its current device state information through any 200OK signaling bearer.
When the current equipment state information of the called equipment is carried through the existing signaling, the method has the advantages that the existing SIP signaling interaction process is not required to be improved, and only the structure of the existing signaling (183 Session progress signaling and two 200OK signaling) is required to be improved, so that the current equipment state information of the called equipment is added in the existing signaling structure.
In the embodiment of the invention, the called equipment can adopt the signaling in the resource reservation media negotiation process to send the equipment state information to the network side, and the network side can adopt the signaling in the resource reservation media negotiation process to send the equipment state information of the called equipment to the calling equipment.
In an embodiment of the present invention, the signaling in the resource reservation medium negotiation process is a 183Session progress signaling.
In a specific implementation, if the 183Session progress signaling is used to carry the current device state information of the called device, a SIP private header field may be newly added in the 183Session progress signaling, where the SIP private header field is used to carry the current device state information of the called device.
For example, in the 183Session progress signaling, a SIP private header field is newly added, where the SIP private header field carries current device Status information of the called device as P-User-Status: low Power, driving. In the SIP private rain, the current device state information of the called device is low battery, and the called user is in a vehicle driving state.
In a specific implementation, after the calling device obtains the device state information of the called device, the device state information of the called device may be displayed on a user interface of the calling device. The calling user (i.e. the user corresponding to the calling device) can acquire the current device state information of the called device on the display screen of the calling device. If the calling user determines to continue to call the called equipment, a normal call flow is initiated; if the calling user determines not to call the called equipment, the call is ended.
For example, after the calling device receives the 183Session progress signaling of the called device, the calling device analyzes the 183Session progress signaling to obtain the information carried by the newly added SIP private header field as follows: P-User-Status: low Power, driving. Since the called device is currently in a low-power state and the called user is currently in a vehicle driving state, it can be determined that the current device state information of the called device can influence the call state. At this time, the calling device may generate a reminder according to the current device status information of the called device and display the reminder on the display screen to remind the calling user.
In the embodiment of the present invention, if the calling subscriber determines to continue to call the called device, the calling device sends the PRACK signaling to the network side, and the subsequent flow may refer to fig. 2. If the calling user determines not to call the called device, the calling device does not need to send PRACK signaling to the network side, and the communication flow of the calling device, the called device and the network side is ended.
In an embodiment of the present invention, if the calling user considers that a long-time call is required to be performed with the called user (i.e., the user corresponding to the called device), but the current electric quantity of the called device is only 10%, and the long-time call may not be supported, the calling user may determine that the called device is unable to complete the call, so the calling user may select an "end call" option on the user interface of the calling device to stop calling the called device.
In another embodiment of the present invention, if the caller considers that a long-time call with the called party is required, but the called party is currently in the teleconference, the caller considers that the called party is inconvenient to answer the call, and therefore, the caller can select the "end call" option in the user interface of the caller to stop calling the called party.
In yet another embodiment of the present invention, if the caller considers that only a short-time call with the callee is required and the callee is currently in a quiet ambient state, the caller considers that the callee is currently convenient to answer the call, and therefore, the caller selects the "continue call" option at the user interface of the caller to continue to call the callee.
It will be appreciated that in a specific application, the current device state information of the called device only provides a reference for the calling user, and the calling user can determine whether to continue to call the called device according to the device state information of the called device. Of course, if the calling user has an emergency and needs to communicate with the called user, the calling user can ignore the equipment state information of the called equipment and continue to call the called equipment.
Therefore, in the embodiment of the invention, after receiving the call request, the current equipment state information of the user is obtained, and the current equipment state information of the user is sent. The calling device can acquire the current device state information of the called device, and then the calling user determines whether to continue to call the called device, so that the calling device can be ensured to establish high-quality call with the called device in some special application scenes, and the user experience is improved.
Referring to fig. 3, another call control method in the embodiment of the present invention is provided, and the following description is made by specific steps.
In the embodiment of the present invention, the call control method provided in the following steps S301 to S302 may be executed by the calling device. Specifically, the following steps S301 to S302 may be performed by a baseband chip in the calling device or a chip module including the baseband chip in the calling device.
Step S301, a call request is output.
In a specific implementation, the calling device and the called device may implement a call based on IMS VoLTE functionality. When the calling device has the requirement of calling the called device, the calling user corresponding to the calling device can input the telephone number corresponding to the called device on the dialing interface corresponding to the calling device and call out. When the calling device calls out the telephone number of the called device, the calling device may output a call request (INVITE) to the network side. After receiving the call request output by the calling device, the network side can forward the call request to the called device.
In the embodiment of the invention, the called equipment can acquire the current equipment state information after receiving the call request. The current device state information of the called device may be used to characterize whether the called device is able to establish a call with the calling device and/or to characterize whether the called device is able to establish a high quality call with the calling device.
In the embodiment of the invention, the current equipment state information of the called equipment can only comprise any one of the current use state information of the called equipment, the current electric quantity information of the called equipment, the current signal quality information of the called equipment and the current environment information of the called equipment, or a plurality of the current use state information of the called equipment, the current electric quantity information of the called equipment, the current signal quality information of the called equipment and the current environment information of the called equipment.
It will be appreciated that, in a specific application, the current device state information of the called device may further include other information corresponding to the called device, where the other information corresponding to the called device may be used to characterize whether the called device can establish a call with the calling device, and/or to characterize whether the called device can establish a high quality call with the calling device.
Step S302, obtaining the current equipment state information of the called equipment.
In a specific implementation, after the called device obtains the current device state information of the called device, the current device state information of the called device can be sent.
In a specific implementation, the called device may send its current device state information to the network side before sending the RINGING notification (i.e., 180RINGING signaling). After receiving the current equipment state information of the called equipment, the network side can forward the equipment state information of the called equipment to the calling equipment, so that the calling equipment can acquire the equipment state information of the called equipment.
In the embodiment of the invention, the called equipment can transmit the current equipment state information of the called equipment through a new signaling. The called device may send the new signaling from the network side, which sends the new signaling to the calling device. After receiving the new signaling, the calling device can acquire the device state information of the called device.
In the embodiment of the invention, the called equipment can adopt the signaling in the resource reservation media negotiation process to send the equipment state information to the network side, and the network side can adopt the signaling in the resource reservation media negotiation process to send the equipment state information of the called equipment to the calling equipment.
In an embodiment of the present invention, the signaling in the resource reservation medium negotiation process is a 183Session progress signaling.
In a specific implementation, if the 183Session progress signaling is used to carry the current device state information of the called device, a SIP private header field may be newly added in the 183Session progress signaling, where the SIP private header field is used to carry the current device state information of the called device.
In a specific implementation, after the calling device obtains the device state information of the called device, the device state information of the called device may be displayed on a user interface of the calling device. The calling user (i.e. the user corresponding to the calling device) can acquire the current device state information of the called device on the display screen of the calling device. If the calling user determines to continue to call the called equipment, a normal call flow is initiated; if the calling user determines not to call the called equipment, the call is ended.
In the embodiment of the present invention, if the calling subscriber determines to continue to call the called device, the calling device sends the PRACK signaling to the network side, and the subsequent flow may refer to fig. 2. If the calling user determines not to call the called device, the calling device does not need to send PRACK signaling to the network side, and the communication flow of the calling device, the called device and the network side is ended.
