[0027] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0029] Before providing a detailed description of the call processing method provided in this application, a brief introduction to the implementation environment (implementation architecture) involved in this application will be given.

[0030] The call processing method provided in this application can be applied to a call processing system. Figure 1 A schematic diagram of one structure of the call processing system is shown. For example... Figure 1 As shown, the call processing system 10 includes a calling user equipment 11, a first called user equipment 12, a dual-number platform 13, an electronic device 14, and a second called user equipment 15. The calling user equipment 11, the first called user equipment 12, the dual-number platform 13, the electronic device 14, and the second called user equipment 15 are connected wirelessly.

[0031] When a calling user makes a call to the first called user's first called user equipment 12 through the calling user equipment 11, the calling user equipment 11 sends a call request to the first called user equipment 12 to realize the call service.

[0032] Electronic device 14 can be used to interact with the one-number-two-device platform 13, for example, to obtain the target tracking area code (TAC) of the calling user equipment from the first call request sent by the one-number-two-device platform 13; the target TAC is located in the first call request sent by the calling user equipment to the first called user equipment.

[0033] Furthermore, the electronic device 14 is also used to determine the target region code corresponding to the target TAC from a pre-stored mapping relationship based on the target TAC; the pre-stored mapping relationship includes multiple TACs and multiple region codes corresponding one-to-one with the multiple TACs.

[0034] Electronic device 14 is also configured to generate a second call request based on the target TAC and the target area code, and send the second call request to the second called user equipment associated with the first called user equipment.

[0035] Optionally, the electronic device 14 can be a physical machine, such as an application server (AS) in the core network, a desktop computer, or a server group composed of multiple servers.

[0036] Optionally, the aforementioned electronic device 14 can also achieve the functions to be performed by using a virtual machine (VM) deployed on a physical machine.

[0037] It should be noted that the electronic device 14 and the dual-machine platform 13 can be independent devices or integrated into the same device; this application does not make any specific limitation in this regard.

[0038] When electronic device 14 and dual-machine platform 13 are integrated into the same device, the communication method between electronic device 14 and dual-machine platform 13 is the same as the communication between internal modules of the device. In this case, the communication process between the two is the same as the communication process between electronic device 14 and dual-machine platform 13 when they are independent of each other.

[0039] Figure 2 This is a schematic diagram illustrating a routing method for a call request from a calling user equipment in a current network. For example... Figure 2 As shown below, the reasons why the second called user equipment has no caller ID when there is an error in the tracking area code and area code of the calling user equipment in this application are explained:

[0040] The calling user equipment's tracking area code and area code are manually entered by maintenance personnel from multiple operators in different regions. Furthermore, because the demand for tracking area codes far exceeds the maximum allowed, the tracking area codes and area codes for the same region often change over time. Additionally, errors may occur in the data entered manually by operator maintenance personnel.

[0041] When a calling user equipment (User Equipment) sends a call request to a first called user equipment (User Equipment), the proxy-call session control function (P-CSCF) in the core network receives the request. Since both the first and second called user equipments have subscribed to the "One Number, Two Devices" service, the "One Number, Two Devices" platform is triggered for the first time. The first and second called user equipments ring simultaneously or in a preset order. However, if the region code corresponding to the calling user equipment's tracking region code stored in the proxy session border controller (PSBC) is incorrect, the region code corresponding to the tracking region code in the p-assered-identity field of the call request sent by the "One Number, Two Devices" platform to the second called user equipment will also be incorrect. This will result in an incorrect phone number format for the calling user equipment in the session initiation protocol (SIP). In this case, a second "One Number, Two Devices" platform will be triggered, leading to the second called user equipment not displaying caller ID.

[0042] In the following embodiments provided in this application, the electronic device 12 is described as an example of being set up independently.

[0043] For ease of understanding, the call processing method provided in this application will be described in detail below with reference to the accompanying drawings.

[0044] Figure 3 This is a flowchart illustrating a call processing method according to an exemplary embodiment. The method can be applied to an electronic device, or to a call processing device connected to or located within an electronic device. The method can also be applied to base station equipment. The following description uses the application of this method to an electronic device as an example to illustrate the method. Figure 3 As shown, the call processing method includes the following steps:

[0045] S201. The electronic device receives the first call request sent by the No. 1 dual-machine platform.

[0046] Among them, the one-number-two-machine platform is used to send the first call request sent by the calling user equipment to the second called user equipment.

[0047] S202, The electronic device obtains the target TAC from the first call request.

[0048] The target TAC is located in the first call request sent by the calling user equipment to the first called user equipment.

[0049] As one possible implementation, the electronic device queries the first call request to find the field name that indicates the target TAC of the calling user equipment in the first call request, and then obtains the field value after that field name.

[0050] It should be noted that the field value after the field name in the target TAC is the target TAC.

[0051] For example, the first call request includes 1001 "52632", 1002 "4561", and 1003 "18500000001"; where 1001 is the field name of the calling user equipment's target TAC, 52632 is the field value of the calling user equipment's target TAC; 1002 is the field name of the calling user equipment's area code, 4561 is the field value of the calling user equipment's area code; 1003 is the field name of the calling user equipment's mobile phone number, and 18500000001 is the field value of the calling user equipment's mobile phone number. The electronic device obtains 52632 as the calling user equipment's target TAC.

[0052] S203. The electronic device determines the target area code corresponding to the target TAC from the pre-stored mapping relationship based on the target TAC.

[0053] The pre-stored mapping relationships include multiple TACs and multiple region codes that correspond one-to-one with each TAC.

[0054] As one possible implementation, the electronic device queries a pre-stored mapping relationship to find a TAC that matches the target TAC, and then queries the target area code corresponding to that TAC through the TAC.

[0055] It should be noted that the pre-stored mapping relationships are pre-set by the operator's maintenance personnel.

[0056] For example, the pre-stored mapping relationships can be shown in Table 1 below:

[0057] Table 1 Pre-stored mapping relationships

[0058] TAC area code 52632 4561 52642 4562 52652 4563 52662 4564

[0059] As shown in Table 1 above, when the TAC in the pre-stored mapping relationship is 52632, the region code is 4561; when the TAC in the pre-stored mapping relationship is 52642, the region code is 4562; when the TAC in the pre-stored mapping relationship is 52652, the region code is 4563; and when the TAC in the pre-stored mapping relationship is 52662, the region code is 4564.

[0060] S204. The electronic device generates a second call request based on the target TAC and the target area code.

[0061] As one possible implementation, the electronic device replaces the first area code in the first call request with the target area code to generate a second call request.

[0062] As another possible implementation, if the first area code and the target area code are inconsistent, the electronic device replaces the first area code in the first call request with the target area code and generates a second call request.

[0063] If the first area code matches the target area code, the electronic device will treat the first call request sent by the calling user equipment to the first called user equipment as the second call request.

[0064] S205, The electronic device sends a second call request to a second called user equipment associated with the first called user equipment.

[0065] Understandably, the technical solution provided in this application obtains the target tracking area code of the calling user equipment and determines the target area code corresponding to the target TAC from a pre-stored mapping relationship based on the target TAC. Further, based on the target TAC and the target area code, a second call request is generated and sent to the second called user equipment associated with the first called user equipment. Thus, since the target TAC and the target area code are correct, the second call request received by the second called user equipment enables normal caller ID display, providing a simple and easy method to resolve the issue of no caller ID display on the second called user equipment.

[0066] In some embodiments, in order to generate a second call request, such as Figure 4 As shown, in the call processing method provided in this application embodiment, the first call request further includes a first area code, and the above-mentioned S204 specifically includes the following steps:

[0067] S301. The electronic device determines whether the first region code and the target region code are consistent.

[0068] As one possible implementation, the electronic device queries the first area code from the first call request and determines whether the target first area code matches the target area code.

[0069] S302. If the first area code and the target area code are inconsistent, the electronic device replaces the first area code in the first call request with the target area code to obtain the second call request.

[0070] As one possible implementation, the electronic device queries the first area code from the first call request and replaces the first area code with the target area code to obtain the second call request.

[0071] For example, the first call request includes 1001 "52632", 1002 "4561", and 1003 "18500000001"; where 1001 is the field name of the calling user equipment's target TAC, 52632 is the field value of the calling user equipment's target TAC, 1002 is the field name of the calling user equipment's area code, 4561 is the field value of the calling user equipment's area code, 1003 is the field name of the calling user equipment's mobile phone number, and 18500000001 is the field value of the calling user equipment's mobile phone number. If the target area code is 4562, the electronic device will replace 4561 with 4562.

[0072] Understandably, the technical solution provided in this application, when the first area code and the target area code are inconsistent, replaces the first area code in the first call request with the target area code to obtain the second call request. This provides a simple and convenient solution to resolve abnormal caller ID display on the second called user equipment.

[0073] like Figure 5 This is a schematic diagram illustrating the routing method for the calling user equipment's call request in this application.

[0074] The calling user equipment sends a call request to the first called user equipment. The proxy-call session control function (P-CSCF) in the core network receives the call request. Since the first and second called user equipments have subscribed to the "one number, two devices" service, the "one number, two devices" platform is triggered. The first and second called user equipments ring simultaneously or in a preset order. The caller ID on the second called user equipment is normal.

[0075] The foregoing mainly describes the solutions provided by the embodiments of this application from a methodological perspective. To achieve the above functions, the call processing device or electronic device includes hardware structures and / or software modules corresponding to the execution of each function.
