Description

Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of communications, and in particular to an emergency call method, a terminal, and a storage medium. Background Art

[0002] At present, the emergency call process of the terminal is that the user makes an emergency call through the USIM card (Universal Subscriber Identity Module) in the terminal. If the emergency call fails due to network problems connected to the USIM card, the terminal will directly end the emergency call and the user needs to manually initiate a new emergency call. However, according to the existing emergency call process, even if the user re-initiates a new emergency call request, the emergency call connection cannot be guaranteed to be successful, resulting in a poor user experience. Summary of the invention

[0003] The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0004] The main purpose of the embodiments of the present invention is to provide an emergency call method, terminal and storage medium, which can initiate an emergency call request through a new call network when the emergency call request fails, thereby improving the probability of successful connection of the emergency call.

[0005] In a first aspect, an embodiment of the present invention provides an emergency call method, which is applied to a terminal, wherein the terminal is equipped with a first USIM card, and the method includes:

[0006] When the emergency call request initiated by the first USIM card to connect to the first call network fails, obtaining failure information;

[0007] Determine the cause of failure according to the failure information;

[0008] An emergency call request is initiated through the second call network according to the failure reason.

[0009] In a second aspect, an embodiment of the present invention further provides a terminal, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program implements the aforementioned emergency call method when executed by the processor.

[0010] In a third aspect, an embodiment of the present invention further provides a computer-readable storage medium, on which an information processing program is stored, and when the information processing program is executed by a processor, the aforementioned emergency call method is implemented.

[0011] An embodiment of the present invention includes: when an emergency call request initiated by a first USIM card to connect to a first call network fails, failure information is obtained; the cause of the failure is determined based on the failure information; switching to a second call network based on the cause of the failure, and initiating an emergency call request through the second call network. According to the solution provided by an embodiment of the present invention, when an emergency call request initiated by a first USIM card to connect to a first call network fails, failure information of the emergency call request can be obtained, and the cause of the failure can be determined based on the failure information. Since the specific cause of the failure of the emergency call request initiated by the first USIM card to connect to the first call network can be clearly identified, an emergency call request can be initiated through the second call network based on the cause of the failure. Since the re-initiated emergency call request does not pass through the first call network with a network anomaly, but initiates the emergency call request through a new call network, the probability of successful connection of the emergency call can be increased.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] It should be noted that although the functional modules are divided in the device schematic and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0023] The present invention provides an emergency call method, a terminal and a storage medium, wherein the emergency call method comprises: in the case that an emergency call request initiated by a first USIM card to connect to a first call network fails, failure information of an upgraded call request can be obtained, and the cause of the failure can be determined based on the failure information, and then the emergency call request can be continued to be initiated through a new call network (i.e., a second call network) based on the cause of the failure. Since the re-initiated emergency call request does not pass through the first call network with a network anomaly, the probability of successful connection of the emergency call can be increased.

[0024] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, Figure 1 FIG. 1 is a schematic diagram of a system architecture for executing an emergency call method provided by an embodiment of the present invention. Figure 1 In the example, the system architecture includes a terminal 110 and a call network, the call network includes an access network and a core network, the terminal 110 includes a first USIM card 111 and a second USIM card 112, the access network includes a first access network 121, a second access network 122 and a third access network 123, the core network includes a first core network 131 and a second core network 132, the first access network 121 is connected to the first core network 131 and the second core network 132 respectively, the second access network 122 is connected to the first core network 131, and the third access network 123 is connected to the second core network 132. The terminal 110 can register with the first access network 121 and the third access network 123 through the first USIM card 111, and can connect to the first core network 131 through the first access network 121 or the third access network 123 to initiate an emergency call to the first core network 131; the terminal 110 can also register with the first access network 121 and the second access network 122 through the second USIM card 112, and can connect to the second core network 132 through the first access network 121 or the second access network 122 to initiate an emergency call to the second core network 132.

[0026] Among them, the first USIM card 111 and the second USIM card 112 can be used to support the terminal 110 to connect to the same operator or different operators; the first core network 131 and the second core network 132 can be core networks of different operators respectively.

[0027] It should be noted that the first access network 121 may include a shared base station, and the shared base station may support services of different operators and be connected to core networks belonging to different operators, which is not solely limited in this embodiment.

[0028] It should be noted that terminal 110 can be used to initiate an emergency call request, can also be used to store the emergency call capability of the core network emergency call of the USIM card, and can also be used to analyze the failure information of the emergency call request and analyze the cause of the failure based on the failure information. This embodiment does not make specific limitations on this.

[0029] In one embodiment, the terminal 110 can initiate an emergency call request to connect to the first call network (including the first access network 121 and the first core network 131) through the first USIM card 111. When the emergency call request fails, the failure information can be obtained, and the cause of the failure can be determined based on the failure information. Then, the emergency call request can be initiated through the second call network (including the second access network 122 and the first core network 131, or including the first access network 121 and the second core network 132, or including the second access network 122 and the second core network 132) based on the cause of failure. Since the re-initiated emergency call request does not pass through the first call network with network abnormalities, the probability of successful connection of the emergency call can be increased.

[0030] The system architecture and application scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those skilled in the art will appreciate that with the evolution of the system architecture and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are equally applicable to similar technical problems.

[0031] Based on the structure of the above system architecture, various embodiments of the information processing method of the present invention are proposed.

[0032] In one embodiment, referring to Figure 2 , Figure 2 This is a flowchart of an emergency call method provided by an embodiment of the present invention. The emergency call method is applied to a terminal. In one embodiment, the emergency call method includes but is not limited to step S210, step S220 and step S230.

[0033] Step S210: When the emergency call request initiated by the first USIM card to connect to the first calling network fails, failure information is obtained.

[0034] In one embodiment, when the emergency call request initiated by the terminal through the first USIM card to connect to the first call network fails, failure information of the emergency call request may be obtained.

[0035] It should be noted that the failure information may include a failure identifier and a failure reason for returning a failure result.

[0036] It should be noted that the first call network may include the first access network and the first core network, and may also include other networks. This embodiment does not make a sole limitation on the first call network.

[0037] Step S220, determining the failure cause according to the failure information.

[0038] In one embodiment, the acquired failure information may be analyzed to determine the failure reason of the emergency call request.

[0039] It should be noted that the failure cause may be an abnormality in the first access network of the first call network, or an abnormality in the first core network of the first call network, which is not specifically limited in this embodiment.

[0040] Step S230: Initiate an emergency call request through the second call network according to the failure reason.

[0041] In one embodiment, the terminal can switch the network for the emergency call from the first call network to the second call network based on the determined cause of failure, and can initiate an emergency call request through the second call network. Since the re-initiated emergency call request does not pass through the first call network where the network abnormality exists, the probability of successful connection of the emergency call can be increased.

[0042] It should be noted that the second call network can be set according to the cause of the failure, and can include the first access network and the second core network, can include the second access network and the second core network, can include the third access network and the first core network, and this embodiment does not specifically limit it.

[0043] In one embodiment, by adopting the above-mentioned steps S210 to S230, when the emergency call request initiated by the terminal through the first USIM card to connect to the first call network fails, the failure information of the emergency call request can be obtained, and the failure cause of the emergency call request can be determined based on the failure information. Then, the emergency call request can be continued to be initiated through a new call network (i.e., the second call network) based on the failure cause. Since the re-initiated emergency call request does not pass through the first call network with network abnormalities, the probability of successful connection of the emergency call can be improved.

[0044] Reference Figure 3The first call network includes a first access network, and the second call network includes a second access network. In one embodiment, step S230 includes but is not limited to the following steps:

[0045] Step S310: When the failure cause indicates that an abnormality occurs in the first access network, the first USIM card is registered to the second access network according to the failure cause, and an emergency call request is initiated to the second access network through the first USIM card.

[0046] In one embodiment, if it is determined that the cause of the failure of the emergency call request is an abnormality in the first access network, it can be explained that the problem of the failure of the first call network connected by the first USIM card lies in the abnormality of the first access network, not in the core network. Since the core network corresponding to the operator corresponding to the first USIM card is normal, the terminal can switch the network for the emergency call from the first access network to the second access network without switching the first USIM card according to the determined cause of failure, and can initiate an emergency call request to the second access network through the first USIM card. Since the re-initiated emergency call request does not pass through the first access network with the network abnormality, the probability of successful connection of the emergency call can be increased.

[0047] It should be noted that the network standard of the first access network and the network standard of the second access network may be different or the same, and this embodiment does not specifically limit this.

[0048] It should be noted that the network standards of the first access network and the second access network may be the fifth generation mobile communication network standard, the fourth generation mobile communication network standard, or the third generation mobile communication network standard, and this embodiment does not specifically limit it.

[0049] In one embodiment, if the network standard of the first access network of the first call network is the fifth generation mobile communication network standard, and the network standard of the second access network is the third generation mobile communication network standard, when the emergency call request initiated by the terminal through the first USIM card to connect to the first call network fails, the failure information of the emergency call request can be obtained, and then the terminal can analyze the obtained failure information. If it is determined that the failure cause of the emergency call request is an abnormality in the first access network, then the terminal can switch the network for the emergency call from the fifth generation mobile communication network standard of the first call network to the third generation mobile communication network standard of the second access network through CSFB (Circuit Switched Domain FallBack) according to the determined failure cause of the abnormality in the first access network, and can initiate an emergency call request to the second call network through the first USIM card, thereby increasing the probability of successful connection of the emergency call.

[0050] Reference Figure 4 The terminal is also equipped with a second USIM card, the first call network includes a first access network and a first core network, the second call network includes a second core network, and both the first USIM card and the second USIM card are registered with the first access network. In one embodiment, step S230 includes but is not limited to the following steps:

[0051] Step S410: When the failure cause indicates that an abnormality occurs in the first core network, an emergency call request is initiated to the second core network through the first access network using the second USIM card according to the failure cause.

[0052] In one embodiment, when the cause of failure is indicated as an abnormality in the first core network, it can be determined that there is an abnormality in the operator network corresponding to the first USIM card. Then, without switching to the first access network, the terminal can switch the first USIM card currently used for emergency call requests to the second USIM card, and use the second USIM card to initiate an emergency call request to the second core network through the first access network. Since the re-initiated emergency call request does not pass through the first core network with the network abnormality, the probability of successful connection of the emergency call can be increased.

[0053] The first USIM card and the second USIM card may be connected to the core network of their corresponding operators through the same access network; the first core network and the second core network may be core networks of different operators respectively.

[0054] Reference Figure 5 The terminal is also equipped with a second USIM card, the first call network includes a first access network and a first core network, the second call network includes a second access network and a second core network, and the first USIM card and the second USIM card are both registered with the first access network. In one embodiment, step S230 includes but is not limited to the following steps:

[0055] Step S510: When the failure cause indicates that an abnormality occurs in the first core network, the second USIM card is registered to the second access network according to the failure cause, and an emergency call request is initiated to the second core network through the second access network using the second USIM card.

[0056] In one embodiment, when the failure cause indicates that an abnormality occurs in the first core network to which the first USIM card is connected, it can be determined that an abnormality occurs in the operator network corresponding to the first USIM card. Then, the second USIM card can be registered to the second access network based on the failure cause, and then an emergency call request is initiated to the second core network through the second access network through the second USIM card. Since the re-initiated emergency call request does not pass through the first core network with the network abnormality, the probability of successful connection of the emergency call can be increased.

[0057] It should be noted that the first USIM card and the second USIM card can be connected to the core network of their corresponding operators through the same access network, and at the same time connected to the core network of their corresponding operators through different access networks, or they can be connected to the core network of their corresponding operators through different access networks respectively. This embodiment does not specifically limit this.

[0058] It should be noted that the first core network and the second core network may be core networks of different operators respectively, and this embodiment does not make a sole limitation thereto.

[0059] Reference Figure 6 In one embodiment, the emergency call method includes but is not limited to the following steps:

[0060] Step S610, obtaining dialing information for initiating a call request, and when the call request is determined to be an emergency call request according to the dialing information, displaying a dialing button;

[0061] Step S620: when trigger information indicating that the dial button is triggered is obtained, an emergency call request for connecting to the first call network is initiated through the first USIM card;

[0062] Step S630, when the emergency call request initiated by the first USIM card to connect to the first call network fails, obtaining failure information;

[0063] Step S640, determining the failure cause according to the failure information;

[0064] Step S650: Initiate an emergency call request through the second calling network according to the failure reason.

[0065] In one embodiment, the terminal obtains dialing information for initiating a call request. When it is determined that the call request corresponding to the dialing information is an emergency call request, a dial button can be displayed on the screen of the terminal. When the terminal obtains trigger information indicating that the dial button is triggered, the terminal can initiate an emergency call request to connect to the first call network through the first USIM card. If the emergency call request to connect to the first call network initiated by the first USIM card fails, the failure information can be obtained and the cause of the failure can be determined based on the failure information. Then, the emergency call request can be initiated through the second call network based on the cause of the failure. Since the re-initiated emergency call request does not pass through the first call network with the network abnormality, the probability of successful connection of the emergency call can be increased.

[0066] In one embodiment, the terminal may include a first USIM card and a second USIM card. When the dialing information determines that the call request is a non-emergency call request, the terminal can control the display module to merge the two dial buttons corresponding to different USIM cards into one dial button, that is, display one dial button. That is, when the user needs to initiate an emergency call, he only needs to issue an emergency call request through one dial button. The USIM card selected for the subsequent emergency call and the call network corresponding to the USIM card are automatically controlled by the terminal. When an emergency call fails, the terminal can obtain the failure information and determine the cause of the failure based on the failure information, and then initiate an emergency call request through the second call network based on the cause of the failure. Since the re-initiated emergency call request does not pass through the first call network with a network abnormality, the probability of successful connection of the emergency call can be increased.

[0067] It should be noted that the first USIM card and the second USIM card can be used to support the terminal to connect to different operators, which is not limited to this embodiment.

[0068] In one embodiment, for a terminal provided with two USIM cards (including a first USIM card and a second USIM card), the terminal obtains dialing information for initiating a call request. When it is determined that the call request corresponding to the dialing information is an emergency call request, the terminal can control the display module to merge the two dial buttons corresponding to different USIM cards into one dial button, that is, display one dial button. That is, when the user needs to initiate an emergency call, only one dial button is required to issue an emergency call request. The USIM card selected for the subsequent emergency call and the call network corresponding to the USIM card are automatically controlled by the terminal. When trigger information indicating that the dial button is triggered is obtained, the first emergency call capability supported by the core network to which the first USIM card belongs and the second emergency call capability supported by the core network to which the second USIM card belongs can be obtained respectively. According to the obtained first emergency call capability and the second emergency call capability, an emergency call request can be initiated again. By comparing the call capability of the emergency call when the dual cards are registered, a call network with strong call capability can be automatically selected to avoid the problem that the user selects a core network with poor support capability, resulting in emergency call delays. When an emergency call fails, the terminal can also obtain failure information and determine the cause of the failure based on the failure information, and then initiate an emergency call request through the second call network based on the cause of the failure without manual redialing. Since the re-initiated emergency call request does not pass through the first call network where the network abnormality exists, the probability of successful connection of the emergency call can be increased.

[0069] In one embodiment, for a terminal provided with two USIM cards (including a first USIM card and a second USIM card), the terminal obtains dialing information for initiating a call request. When it is determined that the call request corresponding to the dialing information is an emergency call request, the terminal can control the display module to merge the two dial buttons corresponding to different USIM cards into one dial button, that is, display one dial button. That is, when the user needs to initiate an emergency call, only one dial button is required to issue an emergency call request, and the USIM card selected for the subsequent emergency call and the call network corresponding to the USIM card are automatically controlled by the terminal. When trigger information indicating that the dial button is triggered is obtained, the first emergency call capability supported by the core network to which the first USIM card belongs and the second emergency call capability supported by the core network to which the second USIM card belongs can be obtained respectively. When the first emergency call capability of the first USIM card is greater than the second emergency call capability of the second USIM card, it can be determined that the emergency call is made through the first call network of the first USIM card. By comparing the call capabilities of the emergency phone when the dual cards are registered, the first call network with stronger capabilities can be automatically selected to avoid the problem that the user selects a core network with poor support capabilities, resulting in emergency call delays. When an emergency call fails, the terminal can also obtain failure information and determine the cause of the failure based on the failure information. For example, if it is determined that the cause of the failure of the emergency call request is an abnormality in the first access network, then it can be obtained from the failure cause that the core network corresponding to the operator corresponding to the first USIM card is normal. Then, the terminal can switch the call network currently initiating the emergency call from the first access network to the second access network according to the determined cause of failure, and can initiate an emergency call request to the second access network through the first USIM card. Since the re-initiated emergency call request does not pass through the first access network with the network abnormality, the probability of successful connection of the emergency call can be increased.

[0070] It should be noted that the first emergency call capability may be a voice capability or other capabilities, which is not specifically limited in this embodiment.

[0071] It should be noted that voice capabilities can be divided into four levels. The first level may be that emergency services are not supported. The second level may be that emergency services are provided only through NR (New Radio) connected to 5GCN (5th Generation Core Network), and the third level may be that emergency services are provided only through E-UTRA (Evolved Universal Mobile Telecommunication System Territorial Radio Access) connected to 5GCN. The fourth level may be that emergency services can be provided both through NR and through E-UTRA connected to 5GCN. The highest level can be set, and the stronger the voice capability.

[0072] In one embodiment, for a terminal equipped with two USIM cards (including a first USIM card and a second USIM card), when an emergency call is needed, a first voice capability supported by the core network to which the first USIM card belongs and a second voice capability supported by the core network to which the second USIM card belongs can be obtained respectively. When the voice capability of the first USIM card is greater than the voice capability of the second USIM card, it can be determined that the emergency call is made through the first call network of the second USIM card. By comparing the call capabilities of the emergency calls when the dual cards are registered, the first call network with stronger capabilities can be automatically selected to avoid the problem of emergency call delays caused by the user selecting a core network with poor support capabilities.

[0073] Reference Figure 7 The terminal includes a first USIM card and a second USIM card. In one embodiment, the emergency call method includes but is not limited to the following steps:

[0074] Step S710, judging whether the first USIM card and the second USIM card of the terminal are registered in the shared base station through the flag bit in the SIB (Service Independent Building Block) message; if so, executing step S720, if not, executing step S790;

[0075] Step S720, obtaining and storing the voice capabilities of the emergency call of the first USIM card and the second USIM card in the core network;

[0076] Step S730: When the acquired call request is an emergency call request, it is determined that the voice capability of the first USIM card is greater than the voice capability of the second USIM card, and the terminal establishes an emergency call through the first call network (including the first access network and the first core network) of the first USIM card;

[0077] Step S740, determining whether the terminal successfully establishes an emergency call through the first call network of the first USIM card, if so, executing step S790, if not, executing step S750;

[0078] Step S750, determining whether the cause of the emergency call failure is the access network on the base station side or the core network; if it is the core network, executing step S760, if it is the access network, executing step S780;

[0079] Step S760, the terminal establishes an emergency call through the second call network (including the first access network and the second core network) of the second USIM card;

[0080] Step S770, determining whether the terminal successfully establishes an emergency call through the second call network of the second USIM card, if so, executing step S790, if not, executing step S780;

[0081] Step S780: The terminal changes the network standard of the current call network through CSFB on the current USIM card to obtain a third call network (such as the current call network includes the second access network and the second core network, or the third access network and the first core network), and establishes an emergency call through the third call network;

[0082] Step S790, completing the call through the current calling network.

[0083] In one embodiment, the first USIM card and the second USIM card of the terminal are both registered in a shared base station. The terminal can obtain and store the voice capabilities of the first USIM card and the second USIM card for emergency calls in the corresponding core networks. When the user uses the terminal to initiate an emergency call request, the voice capabilities of the first USIM card and the second USIM card can be determined. If the voice capability of the first USIM card is greater than the voice capability of the second USIM card, the terminal can establish an emergency call through the first call network of the first USIM card. If the establishment is successful, the call is completed through the current call network. If the establishment fails, the reason for the failure needs to be analyzed. If the reason for the failure is the access network on the base station side, the terminal changes the network standard of the current call network through CSFB on the current USIM card to obtain a third call network, and establishes an emergency call through the third call network; if the reason for the failure is the core network, the terminal can switch the USIM card connected to the call network to the second USIM card, and establish an emergency call through the second call network of the second USIM card. Since the re-initiated emergency call request does not pass through the first call network with a network abnormality, the probability of successful connection of the emergency call can be improved.

[0084] like Figure 8 As shown, Figure 8The emergency call device of the terminal includes: an acquisition module, which is used to acquire failure information when the emergency call request initiated by the first USIM card to connect to the first call network fails; a determination module, which is used to determine the failure cause according to the failure information; and a call module, which is used to switch to the second call network according to the failure cause, and initiate the emergency call request through the second call network. When the emergency call request initiated by the first USIM card in the terminal to connect to the first call network fails, the acquisition module can acquire the failure information of the emergency call request, the determination module can determine the failure cause of the emergency call request according to the failure information, and then the call module can switch to the second call network according to the failure cause, and initiate the emergency call request through the second call network. Since the re-initiated emergency call request does not pass through the first call network with network anomalies, the probability of successful connection of the emergency call can be increased.

[0085] In one embodiment, the first call network includes a first access network, the second call network includes a second access network, and the call module is further used to register the first USIM card to the second access network according to the failure cause when the failure cause indicates that the first access network is abnormal, and initiate an emergency call request to the second access network through the first USIM card. When the emergency call request initiated by the first USIM card in the terminal to connect to the first call network fails, the acquisition module can obtain the failure information of the emergency call request, and then the determination module can analyze the acquired failure information. If it is determined that the failure cause of the emergency call request is that the first access network is abnormal, then the call module can switch the network of the emergency call from the first call network to the second call network according to the determined failure cause of the first access network being abnormal, and initiate an emergency call request to the second call network through the first USIM card. Since the re-initiated emergency call request does not pass through the first call network with network abnormalities, the probability of successful connection of the emergency call can be increased.

[0086] In one embodiment, the terminal is also equipped with a second USIM card, the first USIM card and the second USIM card are both registered to the first access network, the first call network also includes the first core network, the second call network includes the second core network, and the call module is also used to initiate an emergency call request to the second core network through the first access network using the second USIM card according to the failure cause when the failure cause indicates that the first core network is abnormal. When the emergency call request initiated by the first USIM card to connect to the first call network fails, the acquisition module can obtain the failure information of the emergency call request failure through the Modem, and the determination module can analyze the acquired failure information. If the determination module determines that the reason for the failure of the emergency call request is that the first core network is abnormal, it can be considered that the operator network corresponding to the first USIM card is abnormal, then the call module can not switch the first access network, directly switch the first USIM card to the second USIM card, and then the call module can initiate an emergency call request from the first access network to the second core network through the second USIM card. Since the re-initiated emergency call request does not pass through the first call network with network abnormalities, the probability of successful connection of the emergency call can be improved.

[0087] In one embodiment, the terminal is also equipped with a second USIM card, the first USIM card and the second USIM card are both registered to the first access network, the first call network also includes the first core network, the second call network includes the second core network and the second access network, and the call module is also used to register the second USIM card to the second access network according to the failure cause when the failure cause indicates that the first core network is abnormal, and use the second USIM card to initiate an emergency call request to the second core network through the second access network. When the emergency call request initiated by the first USIM card to connect to the first call network fails, the acquisition module can obtain the failure information of the emergency call request failure through the Modem, and the determination module can analyze the acquired failure information and determine the cause of the emergency call failure. If the determination module determines that the failure cause is that the first core network connected to the first USIM card is abnormal, that is, it can be determined that the operator network corresponding to the first USIM card is abnormal, then the call module can register the second USIM card to the second access network according to the failure cause, and then initiate an emergency call request to the second core network through the second USIM card through the second access network. Since the re-initiated emergency call request does not pass through the first call network with network abnormalities, the probability of successful connection of the emergency call can be improved.

[0088] In one embodiment, the terminal includes a first USIM card and a second USIM card, and the acquisition module can also be used to acquire a first emergency call capability supported by the core network to which the first USIM card belongs and a second emergency call capability supported by the core network to which the second USIM card belongs; the call module can also be used to initiate an emergency call request based on the first emergency call capability and the second emergency call capability. For a terminal equipped with two USIM cards (including the first USIM card and the second USIM card), when an emergency call is required, the acquisition module can respectively acquire the first emergency call capability supported by the core network to which the first USIM card belongs and the second emergency call capability supported by the core network to which the second USIM card belongs, and the call module can initiate an emergency call request based on the acquired first emergency call capability and the second emergency call capability, and can automatically select a network by comparing the call capability of the emergency call when the dual cards are registered, so as to avoid the problem of emergency call delay caused by the user selecting a core network with poor support capability.

[0089] In one embodiment, the emergency call device also includes a display module, which can be used to obtain dialing information for initiating a call request, determine that the call request is an emergency call request based on the dialing information, and display a dial button. When the dialing information for initiating a call request is obtained, and the call request is determined to be an emergency call request based on the dialing information, the display module can control the display module of the terminal to display a dial button, and when the trigger information indicating that the dial button is triggered is obtained, an emergency call request to connect to the first call network is initiated through the first USIM card. That is, the user only needs to issue an emergency call request through a dial button, and the call network selected for the subsequent emergency call is automatically completed by the terminal. Since the re-initiated emergency call request does not pass through the first call network with a network anomaly, the probability of successful connection of the emergency call can be increased.

[0090] In addition, an embodiment of the present invention further provides a terminal, referring to Fig. 9 The terminal 900 includes a memory 920, a processor 910, and a computer program stored in the memory 920 and executable on the processor 910.
