[0038] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] In the current call establishment method, when the first terminal device sends a first call request to the second terminal device and receives a second call request sent by the second terminal device, based on the current call mechanism, the first terminal device will reject the second call request and the second terminal device will reject the first call request, resulting in the failure of call establishment between the first terminal device and the second terminal device and poor call establishment efficiency.

[0041] Figure 1 The flowchart of the call establishment method of one embodiment of the present disclosure is as follows. It should be noted that the call establishment method of the present embodiment can be applied to a call establishment device, which can be configured in an electronic device or chip so that the electronic device or chip can perform a call establishment function.

[0042] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0043] In addition, the call establishment device may also be software in an electronic device, etc. The software may be, for example, call establishment software, etc. In the following embodiments, the execution subject is taken as the first terminal device as an example for description.

[0044] like Figure 1 As shown, the method comprises the following steps:

[0045] Step 101: when a first call request is sent to a second terminal device and a second call request is received from the second terminal device, a candidate reserved call request is determined in the first call request and the second call request based on a call processing strategy.

[0046] In the embodiment of the present disclosure, the situation where a first call request is sent to a second terminal device and a second call request is received from the second terminal device refers to the situation where the first terminal device sends a first call request to the second terminal device and does not receive a first response message for the first call request, but then receives the second call request from the second terminal device; or, the first terminal device receives the second call request from the second terminal device while sending the first call request to the second terminal device.

[0047] In the disclosed embodiment, the first call request may carry the first number; the second call request may carry the second number. Correspondingly, the call processing strategy may include any one of the following: determining the call request corresponding to the larger number of the first number and the second number as a candidate for reserved call request; determining the call request corresponding to the smaller number of the first number and the second number as a candidate for reserved call request; determining the call request corresponding to the number with the larger local number of the first number and the second number as a candidate for reserved call request; the local number is a local number composed of characters preset at multiple consecutive positions in the first number and the second number; determining the call request corresponding to the number with the smaller local number of the first number and the second number as a candidate for reserved call request; determining the call request corresponding to the number with the larger value calculated by the preset algorithm of the first number and the second number as a candidate for reserved call request; determining the call request corresponding to the number with the smaller value calculated by the preset algorithm of the first number and the second number as a candidate for reserved call request.

[0048] In one example, the call processing strategy may be to determine the call request corresponding to the larger number between the first number and the second number as a candidate for reserved call request. Correspondingly, the process of the first terminal device determining the candidate for reserved call request between the first call request and the second call request based on the call processing strategy may be, for example, to compare the first number and the second number to obtain a comparison result; if the comparison result is that the first number is smaller than the second number, the second call request is determined as a candidate for reserved call request; if the comparison result is that the first number is larger than the second number, the first call request is determined as a candidate for reserved call request.

[0049] In another example, the call processing strategy may be to determine the call request corresponding to the smaller number between the first number and the second number as a candidate for reserved call request. Correspondingly, the process of the first terminal device determining the candidate for reserved call request between the first call request and the second call request based on the call processing strategy may be, for example, to compare the first number and the second number to obtain a comparison result; if the comparison result is that the first number is smaller than the second number, the first call request is determined as a candidate for reserved call request; if the comparison result is that the first number is larger than the second number, the second call request is determined as a candidate for reserved call request.

[0050] In another example, the call processing strategy may be to determine the call request corresponding to the number with the larger local number between the first number and the second number as a candidate reserved call request. The local number is a local number composed of characters in a plurality of preset consecutive positions in the first number and the second number. For example, the first number and the second number may be 11-digit numbers, and the number composed of characters in the last 4 digits may be used as the local number. Correspondingly, the process of the first terminal device determining the candidate reserved call request in the first call request and the second call request based on the call processing strategy may be, for example, to compare the local number in the first number and the local number in the second number to obtain a comparison result; if the comparison result is that the local number in the first number is smaller than the local number in the second number, the second call request is determined as a candidate reserved call request; if the comparison result is that the local number in the first number is larger than the local number in the second number, the first call request is determined as a candidate reserved call request.

[0051] In another example, the call processing strategy may be to determine the call request corresponding to the number with the smaller local number in the first number and the second number as a candidate for reserved call request. Correspondingly, the process of the first terminal device determining the candidate for reserved call request in the first call request and the second call request based on the call processing strategy may be, for example, to compare the local number in the first number and the local number in the second number to obtain a comparison result; if the comparison result is that the local number in the first number is smaller than the local number in the second number, the first call request is determined as a candidate for reserved call request; if the comparison result is that the local number in the first number is larger than the local number in the second number, the second call request is determined as a candidate for reserved call request.

[0052] In another example, the call processing strategy may be to determine the call request corresponding to the number with the larger value calculated by combining the preset algorithm in the first number and the second number as a candidate for reserved call request. The preset algorithm may be, for example, a hash algorithm. Correspondingly, the process of the first terminal device determining the candidate for reserved call request in the first call request and the second call request based on the call processing strategy may be, for example, to compare the value corresponding to the first number and the value corresponding to the second number to obtain a comparison result; if the comparison result is that the value corresponding to the first number is less than the value corresponding to the second number, the second call request is determined as a candidate for reserved call request; if the comparison result is that the value corresponding to the first number is greater than the value corresponding to the second number, the first call request is determined as a candidate for reserved call request.

[0053] In another example, the call processing strategy may be to determine the call request corresponding to the number with the smaller value calculated by combining the preset algorithm among the first number and the second number as the candidate reserved call request. Correspondingly, the process of the first terminal device determining the candidate reserved call request among the first call request and the second call request based on the call processing strategy may be, for example, to compare the value corresponding to the first number and the value corresponding to the second number to obtain a comparison result; if the comparison result is that the value corresponding to the first number is smaller than the value corresponding to the second number, the first call request is determined as the candidate reserved call request; if the comparison result is that the value corresponding to the first number is larger than the value corresponding to the second number, the second call request is determined as the candidate reserved call request.

[0054] It should be noted that the call processing strategies in the embodiments of the present disclosure are not limited to the above strategies and may be any strategy in existing technologies or future technologies that can distinguish the first number from the second number and select and determine candidate call reservation requests.

[0055] Among them, the setting of multiple call processing strategies enables each terminal device or two terminal devices that need to communicate to select one of the call processing strategies according to the needs, thereby improving the flexibility of call processing strategy selection.

[0056] Step 102: based on the candidate reserved call requests, retain one of the first call request and the second call request as a target reserved call request.

[0057] In the embodiment of the present disclosure, the process of the first terminal device executing step 102 may, for example, be: when the candidate call retention request is the first call request, determining whether the second terminal device supports call conflict handling capability; determining the target call retention request in the first call request and the second call request in combination with whether the second terminal device supports the call conflict handling capability; and / or, when the candidate call retention request is the second call request, determining the target call retention request in the first call request and the second call request in combination with whether the first terminal device sending the first call request supports the call conflict handling capability.

[0058] In the embodiment of the present disclosure, the second terminal device supports the call conflict handling capability, which means that when the second terminal device sends a second call request and receives a first call request from the first terminal device, the second terminal device can choose to retain the received first call request, so as to combine the second response message of the first terminal device to the second call request to finally determine whether to retain the first call request. Wherein, the second terminal device does not support the call conflict handling capability, which means that when the second terminal device sends a second call request and receives the first call request from the first terminal device, the second terminal device does not retain the first call request.

[0059] Step 103: Based on the target reserved call request, a call establishment process is performed between the first terminal device and the second terminal device.

[0060] In the embodiment of the present disclosure, the process of the first terminal device executing step 103 may, for example, include the following steps: when the target reserved call request is the first call request, sending a second response message for the second call request to the second terminal device; the second response message indicates call rejection; and when a call indication for the first call request returned by the second terminal device is received, performing call establishment processing between the first terminal device and the second terminal device.

[0061] The first terminal device may return a second response message carrying a value of 486 to the second terminal device to indicate that the call is rejected. The first terminal device may receive a call indication carrying a value of 200 returned by the second terminal device, wherein the value 200 indicates that the second terminal device connects the call, and then the call process between the first terminal device and the second terminal device may be carried out.

[0062] In addition, the process of the first terminal device executing step 103 may also include the following steps: when the target reserved call request is a second call request, detecting a call indication for the second call request; sending a call indication to the second terminal device to perform call establishment processing between the first terminal device and the second terminal device.

[0063] Among them, when the target reserved call request is a second call request, the first terminal device can detect the operation of the object on the interface; when the call connection operation of the object is detected, a call indication is sent to the second terminal device; the second terminal device conducts the call process between the first terminal device and the second terminal device according to the call indication.

[0064] Among them, after determining the target reservation call request, the interaction between the first terminal device and the second terminal device can speed up the establishment of the call process between the first terminal device and the second terminal device, and ensure that the call is successfully established.

[0065] In the call establishment method of the embodiment of the present disclosure, by sending a first call request to the second terminal device and receiving a second call request from the second terminal device, based on the call processing strategy, determining a candidate reserved call request among the first call request and the second call request; based on the candidate reserved call request, retaining one of the first call request and the second call request as a target reserved call request; based on the target reserved call request, performing call establishment processing between the first terminal device and the second terminal device; wherein, based on the determined target reserved call request, it is possible to ensure that the call between the first terminal device and the second terminal device is successfully established, thereby improving the call establishment efficiency.

[0066] Figure 2 The flowchart of the call establishment method of one embodiment of the present disclosure is as follows. It should be noted that the call establishment method of the present embodiment can be applied to a call establishment device, which can be configured in an electronic device or chip so that the electronic device or chip can perform a call establishment function.

[0067] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0068] In addition, the call establishment device may also be software in an electronic device, etc. The software may be, for example, call establishment software, etc. In the following embodiments, the execution subject is taken as the first terminal device as an example for description.

[0069] like Figure 2 As shown, the method comprises the following steps:

[0070] Step 201: when a first call request is sent to a second terminal device and a second call request is received from the second terminal device, a candidate reserved call request is determined in the first call request and the second call request based on a call processing strategy.

[0071] Step 202: When the candidate reserved call request is the first call request, a first response message for the first call request returned by the second terminal device is received.

[0072] In the embodiments of the present disclosure, it should be noted that, if the first terminal device supports the call conflict handling capability, the first terminal device may first wait for the first response information returned by the second terminal device; based on the first response information, determine the second response information to be returned to the second terminal device. If the first terminal device does not support the call conflict handling capability, the first terminal device does not need to wait for the first response information returned by the second terminal device, and may directly return the first response information indicating call rejection to the second terminal device.

[0073] Step 203: When the first response message indicates that the call is to continue, determine that the second terminal device supports the call conflict handling capability.

[0074] In the embodiment of the present disclosure, the first response message may indicate a temporary response, and the temporary response indicates that the call is continued. In addition, the first response message may indicate a rejection response, and the rejection response indicates that the call is rejected. The first response message may carry a value less than 200 to indicate a temporary response. Specifically, the value less than 200 may be, for example, 180 for ringing.

[0075] Step 204: When the first response message indicates call rejection, determine that the second terminal device does not support call conflict handling capability.

[0076] In the embodiment of the present disclosure, the first response message may carry a value greater than or equal to 300 to indicate a rejection response. Specifically, the value greater than or equal to 300 may be, for example, 486 for rejection.

[0077] It should be noted that step 203 and step 204 may be in an and / or relationship. That is, in an example, step 203 and step 204 are in an and relationship. The first terminal device may determine whether to execute step 203 or step 204 according to actual conditions. That is, if the first response message indicates that the call is continued, step 203 is executed, and if the first response message indicates that the call is rejected, step 204 is executed.

[0078] In another example, step 203 and step 204 are in an OR relationship. Assuming that there is only step 203, the first terminal device determines whether the condition in step 203 is met, and if so, step 203 is executed, otherwise it is not executed. Assuming that there is only step 204, the first terminal device determines whether the condition in step 204 is met, and if so, step 204 is executed, otherwise it is not executed.

[0079] Step 205: When the second terminal device supports call conflict handling capability, determine that the target reserved call request is the first call request.

[0080] In the embodiment of the present disclosure, in the case where the second terminal device supports the call conflict handling capability, the first terminal device may support the call conflict handling capability, or the first terminal device may not support the call conflict handling capability.

[0081] Wherein, in the case where the second terminal device supports the call conflict handling capability and the first terminal device supports the call conflict handling capability, the call interaction process between the first terminal device and the second terminal device may be as follows, for example: Figure 3 As shown. Figure 3 In the example, the first terminal device is represented by user B; the second terminal device is represented by user A; the candidate reserved call request is the first call request (ie, INVITE) initiated by user B. The call interaction between user A and user B is implemented through the network.

[0082] exist Figure 3In the example, (1) user B initiates an INVITE to user A; at the same time, user A initiates an INVITE to user B. (2) In response to the received INVITE, user A sends a 180 ringing to user B. (3) Based on the received 180 ringing, user B sends a 486 to user A to indicate that the INVITE initiated by user A is rejected. After user B receives the 180 ringing from user A, it determines that user A supports the call conflict handling capability, thereby ensuring that the INVITE initiated by user B needs to be retained, while the INVITE initiated by user A is not retained. Therefore, in response to the INVITE initiated by user A, user B sends a 486 to user A to reject the INVITE initiated by user A. (4) In response to 486, user A sends an ACK to user B to indicate that 486 has been received. (5) User A sends a 200 to user B to indicate that the call is connected. (6) User B connects the call and sends an ACK to user A to indicate that 200 has been received.

[0083] Wherein, in the case where the second terminal device supports the call conflict handling capability and the first terminal device does not support the call conflict handling capability, the call interaction process between the first terminal device and the second terminal device may be as follows: Figure 4 As shown. Figure 4 In the example, the first terminal device is represented by user B; the second terminal device is represented by user A; the candidate reserved call request is the first call request (ie, INVITE) initiated by user B. The call interaction between user A and user B is implemented through the network.

[0084] exist Figure 4 In the example, (1) user B initiates an INVITE to user A; at the same time, user A initiates an INVITE to user B. (2) In response to the received INVITE, user B sends a 486 to user A to indicate that the INVITE initiated by user A is rejected. (3) In response to the received INVITE, user A sends a 180 ringing to user B to indicate to user B that user A supports the call conflict handling capability. (4) In response to the received 486, user A sends an ACK to user B to indicate that the 486 has been received. After receiving the 486 from user B, user A determines that user B does not support the call conflict handling capability, and thus can send a 200 to user B. (5) User A sends a 200 to user B to indicate that the call is connected. (6) User B connects the call and sends an ACK to user A to indicate that the 200 has been received.

[0085] Step 206: When the second terminal device does not support the call conflict handling capability and the first terminal device supports the call conflict handling capability, determine that the target reserved call request is the second call request.

[0086] In the embodiment of the present disclosure, when the second terminal device does not support the call conflict handling capability, and the first terminal device supports the call conflict handling capability, the call interaction process between the first terminal device and the second terminal device can be as follows: Figure 5 As shown. Figure 5 In the example, the first terminal device is represented by user B; the second terminal device is represented by user A; the candidate reserved call request is the first call request (ie, INVITE) initiated by user B. The call interaction between user A and user B is implemented through the network.

[0087] exist Figure 5 In the example, (1) user B initiates an INVITE to user A; at the same time, user A initiates an INVITE to user B. (2) In response to the received INVITE, user A sends a 486 to user B to indicate that the INVITE initiated by user B is rejected. (3) In response to the received 486, user B sends an ACK to user A to indicate that the 486 is received. (4) Based on the received 486, user B sends a 180 ringing to user A. After receiving the 486 from user A, user B determines that user A does not support call conflict handling capabilities, and thus determines that the INVITE initiated by user A needs to be retained, while the INVITE initiated by user B needs to be retained. Therefore, in response to the INVITE initiated by user A, a 180 ringing is sent to user A. (5) User B sends a 200 to user A to indicate that the call is connected. (6) User A connects the call and sends an ACK to user B to indicate that the 200 is received.

[0088] Step 207: Based on the target reserved call request, a call establishment process is performed between the first terminal device and the second terminal device.
