Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to a method, apparatus, computer device, and storage medium for displaying emergency call capabilities. Background Art

[0002] Emergency call capability refers to the ability of components such as terminals (such as mobile phones), communication network infrastructure and Subscriber Identity Module (SIM) cards to work together in an emergency to ensure that users can successfully initiate and complete emergency calls.

[0003] Currently, when a terminal carries a SIM card from a certain carrier but is outside of its network coverage, it will be forced to search for and attach to the network of another available carrier, entering "Emergency Call Only" mode and displaying "Emergency Call Only" on the terminal. However, during terminal development, testers may sometimes encounter issues where they are unable to dial emergency numbers while testing them. Unlike the aforementioned scenario, in this scenario, the terminal is generally within the network coverage of the carrier's SIM card. In addition to issues with the terminal itself, the inability to dial emergency numbers may also be due to the local carrier's network not supporting the emergency call function. This inability to dial emergency numbers, which is not caused by the terminal itself, can impact the overall development speed of the terminal. Summary of the Invention

[0032] In order to make the purpose, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0033] An emergency call refers to dialing emergency or distress numbers using a terminal (such as a mobile phone). The urgency of these numbers has led countries to mandate that they use any available network. Emergency call capability refers to the ability of components such as the terminal (e.g., a mobile phone), the communications network infrastructure, and the SIM card to work together in an emergency to ensure users can successfully initiate and complete emergency calls. Currently, these calls can be made even if the terminal has no phone credit or even a SIM card. In practice, for example, if a terminal uses a China Mobile SIM card and enters an area with no China Mobile signal but only China Unicom signal, while it cannot find a China Mobile signal, it will find a China Unicom signal, also part of the Global System for Mobile Communications (GSM) network. The terminal will then automatically attach to China Unicom's network, providing only emergency call services and displaying "Emergency Calls Only." However, during terminal development, testers often encounter issues with emergency numbers being unable to be dialed. After analysis, the developer identifies the reason for the failure as the local carrier's network not supporting emergency call functionality. This significantly wastes the time of testers and developers, slowing down development.

[0034] In response to the above-mentioned problems, the embodiments of the present disclosure provide a method for displaying emergency call capabilities, including, upon receiving an emergency call capability display instruction, polling and searching for air interface signaling according to a preset period; determining the current radio resource control (RRC) state of the terminal; determining the target signaling based on the RRC state and the found air interface signaling, and determining the current network's support result for the emergency call capability based on the target signaling; controlling the terminal to display a preset flag based on the support result; the preset flag is used to indicate that the terminal supports the emergency call capability under the current network state. In this way, the terminal tester can clearly see the specific situation of the current network's support for the emergency call capability directly from the terminal display screen, reducing ineffective testing work and improving the terminal's R&D speed.

[0035] The display method of the emergency call capability provided by the present disclosure can be applied to Figure 1 In the application environment shown, the method for displaying emergency call capabilities is applied to an emergency call capability display system. The emergency call capability display system includes a terminal 100 and a base station 200. The terminal 100 can establish a communication connection with the base station 200. In one embodiment, the terminal 100 is a device that supports displaying emergency call capabilities, and may include but is not limited to various mobile phones, tablet computers, and portable wearable devices.

[0036] It should be noted that the method for displaying the emergency call capability provided in the embodiment of the present disclosure can be executed by the terminal 100 described above.

[0037] In addition, the display method of the emergency call capability provided by the embodiment of the present disclosure can be executed by a display device of the emergency call capability, and the display device of the emergency call capability can be hardware or software. When the display device of the emergency call capability is hardware, it can be various electronic devices with display functions, including but not limited to mobile phones, tablet computers, vehicle-mounted equipment, portable wearable devices, etc. When the display device of the emergency call capability is software, it can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules, or it can be implemented as a single software or software module. No specific limitation is made here.

[0038] In one embodiment, Figure 2 As shown, the embodiment of the present disclosure provides a method for displaying emergency call capabilities. The embodiment of the present disclosure mainly applies this method to Figure 1 The terminal 100 in FIG. 1 is used as an example.

[0039] S11 . Upon receiving an emergency call capability display instruction, search for air interface signaling by polling according to a preset period.

[0040] First, considering that the need to open the modem communication log (modem log) may cause an increase in terminal power consumption and memory, the display instruction of the emergency call capability can be triggered by the user to issue the corresponding control. For example, in the settings (setting)-mobile connection (Mobile network)-SIM1 / SIM2-SIM card settings, add the switch for the function option "Display ECC", and users who need this function can turn on the function in the settings as needed. In this way, when it is detected that the user triggers the emergency call capability display control (such as Display ECC), it is determined that the display instruction of the emergency call capability is received. In the above scheme, a control that can freely turn on the emergency call capability display is provided in the terminal, so that the user can independently control whether the terminal displays the emergency call capability according to the actual use of the terminal, thereby improving the flexibility of controlling the display of the emergency call capability.

[0041] Then, when it is determined that a display instruction for emergency call capability has been received, the Over The Air (OTA) signaling is searched for in a polling manner according to a preset period. The duration of the preset period is preset, such as a default value, or a value set by relevant personnel according to actual conditions. For another example, the duration of the preset period is 30 seconds (s). The air interface signaling includes the Evolved Packet System Mobility Management (EMM) Attach Accept message and the System Information Block Type 1 (SIB1) message. The way to find the air interface signaling can be to directly print the modem communication log (modem log) and obtain the corresponding air interface signaling according to the log record.

[0042] In one embodiment, the terminal software can be divided into two parts: the Application Processor (AP) and the Baseband Processor (BP). When a call or data connection is needed, the AP communicates with the BP; the BP, also known as a modem, is primarily responsible for making calls and data connections. Therefore, upon detecting a user triggering an emergency call capability display command, the AP can send a query command to the modem, which then polls for air interface signaling at a preset interval.

[0043] S12: Determine the current radio resource control (RRC) state of the terminal.

[0044] The Radio Resource Control (RCC) state includes an idle state (IDLE) and a connected state (CONNECTED).

[0045] Since the RRC state during signaling interaction between the terminal and the base station changes with the terminal's business activities and network scheduling strategy, and different RRC states correspond to different air interface signaling, it is necessary to first determine the current RRC state of the terminal.

[0046] Specifically, the method for determining the current RRC state of the terminal can be determined by the current signaling interaction between the terminal and the base station. For example, if the terminal only performs cell selection or monitors paging and does not establish a radio bearer with the base station, it is determined that the terminal is currently in an idle state; if an RRC connection has been established between the terminal and the base station and data and signaling transmission can be performed, it is determined that the terminal is currently in a connected state. The current RRC state of the terminal can also be determined by signaling packet capture or terminal-side debugging interface, which is not limited in this disclosure.

[0047] S13. Determine target signaling according to the RRC state and the found air interface signaling.

[0048] Specifically, since different RRC states correspond to different air interface signaling, it is necessary to determine the target signaling based on the RRC state and the found air interface signaling, that is, to determine the air interface signaling corresponding to the current RRC state as the target signaling, so as to avoid signaling misjudgment due to mismatch between the RRC state and the air interface signaling, thereby affecting the judgment of the emergency call capability support situation.

[0049] S14. Determine the current network's support result for the emergency call capability according to the target signaling.

[0050] Specifically, parse the target signaling, obtain the parsed field corresponding to the target signaling, and analyze the parsed field to obtain the current network's support result for the emergency call capability. For example, when the target signaling is an EMM additional accept message, parse the EMM additional accept message to obtain the parsed field corresponding to the EMM additional accept message, and analyze the Emergency bearer services in S1 mode field in the parsed field corresponding to the EMM additional accept message to obtain the current network's support result for the emergency call capability. When the target signaling is a SIB1 message, parse the SIB1 message to obtain the parsed field corresponding to the SIB1 message, and analyze the Internet Protocol Multimedia Subsystem Emergency Call Support (ims-EmergencySupport-r9) field of the non-critical extension field in the parsed field corresponding to the SIB1 message to obtain the current network's support result for the emergency call capability.

[0051] S15. Control the terminal to display a preset logo according to the support result.

[0052] The preset flag is used to indicate that the terminal supports emergency call capabilities under the current network status. The specific shape and color of the preset flag are not limited in this disclosure. For example, the preset flag can be the letters "ECC". The support results include supporting emergency call capabilities and not supporting emergency call capabilities.

[0053] Specifically, the method of controlling the terminal to display a preset sign according to the support result may be that when the support result is that the emergency call capability is supported, the terminal is controlled to display a preset sign, for example, Figure 3 As shown, the "ECC" mark is displayed next to the SIM card signal in the terminal status bar. When the support result is that the emergency call capability is not supported, the control terminal displays the unsupported mark, or the control terminal does not display the preset mark. In this way, when the support result is that the emergency call capability is supported, the control terminal displays the preset mark, and when the support result is that the emergency call capability is not supported, the preset mark is not displayed or the unsupported mark is displayed, so that the user can judge whether the current network supports the emergency call capability based on whether the preset mark is displayed or the specific mark is displayed.

[0054] In one embodiment, when the terminal carries multiple subscriber identity module (SIM) cards, controlling the terminal to display a preset mark according to the support result includes: controlling the terminal to display a preset mark according to the support result corresponding to each SIM card. Figure 4 As shown, if the terminal includes two SIM cards, and both SIM cards support emergency call capabilities, an "ECC" logo will be displayed next to the signals of both SIM cards. The support determination process for multiple SIM cards is the same as for a single card, except that the number of determinations is increased. Therefore, the steps for determining support results for multiple SIM cards will not be repeated here. Thus, when a terminal carries multiple Subscriber Identity Module (SIM) cards, it can control the terminal to display a preset logo based on the support results corresponding to each SIM card, allowing the user to promptly understand the emergency call capability support status of each SIM card.

[0055] In one embodiment, after the modem determines the support result, it sends the support result to the AP through the Ril layer. After receiving the support result, the AP determines whether to display the icon based on the support result (which can be implemented according to the VoLTE and VoWiFi icon display process).

[0056] In the above solution, upon receiving a command to display emergency call capabilities, the system first searches for air interface signaling at a preset periodic interval to determine the terminal's current Radio Resource Control (RRC) state. Next, it determines target signaling based on the RRC state and the retrieved air interface signaling, and determines the current network's support for emergency call capabilities based on the target signaling. Finally, based on the support result, the system controls the terminal to display a preset flag. The preset flag indicates that the terminal supports emergency call capabilities under the current network state. This allows the system to parse the air interface signaling exchanged between the terminal and the network to determine whether the current network supports emergency call capabilities, and then displays a preset icon based on the support result. This allows terminal testers to clearly see the network's support for emergency call capabilities directly on the terminal display, reducing unnecessary testing efforts and avoiding unnecessary bug reports to developers. This saves testers time and the time it takes to find the cause of the bug, thereby accelerating terminal development. Furthermore, users who need to make emergency calls can be prompted to move their physical location or change their carrier's SIM card to verify the functioning of emergency call capabilities, ensuring user safety while improving the user experience.

[0057] In one embodiment, the RRC state includes a connected state and an idle state, and the air interface signaling includes an Evolved Packet System Mobility Management EMM Attach Accept message and a System Information Block 1 SIB1 message. Figure 5 As shown, the method of determining the target signaling according to the RRC state and the found air interface signaling may include the following steps:

[0058] S121. Determine whether the RRC state is the connected state, and execute step S131 when the RRC state is the connected state, and execute step S132 when the RRC state is not the connected state.

[0059] Specifically, the method of determining whether the RRC state is the connected state is the same as the method of determining the current RRC state of the terminal in step S12, which will not be repeated here.

[0060] S131. Determine the EMM attachment acceptance message most recently found in the air interface signaling as the target signaling.

[0061] Specifically, since the corresponding air interface signaling is obtained by printing the modem log when searching for the air interface signaling, when it is determined that the current RRC state is the connected state, the EMM additional acceptance message with the time closest to the current time in the modem log is determined as the target signaling.

[0062] Exemplarily, when the modem log printout is as shown in Table 1 below, the EMM additional acceptance message corresponding to the time 17:47:31:675 is determined as the target signaling.

[0063] Table 1

[0064]

[0065]

[0066] S132: When it is determined that the RRC state is the idle state, the SIB1 message most recently found in the air interface signaling is determined as the target signaling.

[0067] Similarly, when it is determined that the current RRC state is the idle state, the SIB1 message with the time closest to the current time in the modem log is determined as the target signaling.

[0068] Exemplarily, when the modem log printout is as shown in Table 2 below, the SIB1 message corresponding to the time 08:57:32:910 is determined as the target signaling.

[0069] Table 2

[0070]

[0071]

[0072] In the above solution, the target signaling can be determined from multiple air interface signalings according to the RRC status, so that the support status of the emergency call capability can be determined from the target signaling and displayed, thereby ensuring user safety and improving user experience.

[0073] In one embodiment, Figure 6 As shown, the current network's support result for emergency call capability is determined based on the target signaling, including:

[0074] S141. Determine that the target signaling is an EMM attachment accept message.

[0075] S142. Determine whether the value of the penultimate bit of the Evolved Packet System EPS Network Feature Support field of the EMM Attach Accept message is 1; and if the value of the penultimate bit of the Evolved Packet System EPS Network Feature Support field of the EMM Attach Accept message is 1, execute step S143; if the value of the penultimate bit of the Evolved Packet System EPS Network Feature Support field of the EMM Attach Accept message is 0, execute step S144.

[0076] Specifically, the EMM additional acceptance message is parsed to find out whether the value corresponding to the Emergency bearer services inS1 mode of the penultimate bit of the Evolved Packet System EPS network feature support field is 1. If it is 1, the emergency call capability is supported; if it is 0, the emergency call capability is not supported.

[0077] Exemplarily, when the content included in EPS network feature support is as follows, if the value corresponding to the second-to-last bit of Emergency bearer services in S1 mode is 0, it is determined that the current network does not support emergency call capability.

[0078] Element ID:0x64

[0079] Length:1

[0087] S143: Determine whether the current network supports emergency call capability.

[0088] S144: Determine that the current network does not support emergency call capability.

[0089] In the above scheme, when the target signaling is an EMM additional acceptance message, the support status of the emergency call capability can be actively determined from the EMM additional acceptance message, which reduces invalid testing work and avoids invalid bugs presented to R&D personnel, saving the test time of testers and the time of R&D personnel to find the cause of bugs, thereby improving the R&D speed of the terminal, ensuring user safety, and improving user experience.

[0090] In one embodiment, Figure 7 As shown, the current network's support result for emergency call capability is determined based on the target signaling, including:

[0091] S145. Determine that the target signaling is a SIB1 message.

[0092] S146. Determine whether the Internet Protocol Multimedia Subsystem Emergency Call Support field of the non-critical extension field of the SIB1 message is 1; and when the Internet Protocol Multimedia Subsystem Emergency Call Support field of the non-critical extension field of the SIB1 message is 1, execute step S143; when the Internet Protocol Multimedia Subsystem Emergency Call Support field of the non-critical extension field of the SIB1 message is 0, execute step S144.

[0093] Specifically, the SIB1 message is parsed to find out whether the value of the Internet Protocol Multimedia Subsystem Emergency Call Support field (ims-EmergencySupport-r9) of the non-critical extension field (nonCriticalExtension) is True (1) or False (0). As above, if it is 1, the emergency call capability is supported, and if it is 0, the emergency call capability is not supported.

[0094] Exemplarily, when nonCriticalExtension includes the following content, and the value of ims-EmergencySupport-r9 is 0, it is determined that the current network does not support emergency call capability.

[0098] S143: Determine whether the current network supports emergency call capability.

[0099] S144: Determine that the current network does not support emergency call capability.

[0100] In the above scheme, when the target signaling is a SIB1 message, the support status of the emergency call capability can be actively determined from the SIB1 message, which reduces invalid testing work and avoids invalid bugs presented to R&D personnel, saving the test time of testers and the time of R&D personnel to find the cause of bugs, thereby improving the R&D speed of the terminal, ensuring user safety, and improving user experience.

[0106] In one embodiment, the determination module is specifically used to: determine that the current network supports emergency call capability when the target signaling is an EMM additional accept message and the value of the second to last bit of the evolved packet system EPS network feature support field of the EMM additional accept message is 1; determine that the current network does not support emergency call capability when the target signaling is an EMM additional accept message and the value of the second to last bit of the evolved packet system EPS network feature support field of the EMM additional accept message is 0; determine that the current network does not support emergency call capability when the target signaling is an SIB1 message and the Internet Protocol Multimedia Subsystem Emergency Call Support field of the non-critical extension field of the SIB1 message is 1; determine that the current network supports emergency call capability when the target signaling is a SIB1 message and the Internet Protocol Multimedia Subsystem Emergency Call Support field of the non-critical extension field of the SIB1 message is 0.

Next, it determines target signaling based on the RRC state and the retrieved air interface signaling, and determines the current network's support for emergency call capabilities based on the target signaling. Finally, based on the support result, the system controls the terminal to display a preset flag. The preset flag indicates that the terminal supports emergency call capabilities under the current network state. This allows the system to parse the air interface signaling exchanged between the terminal and the network to determine whether the current network supports emergency call capabilities, and then displays a preset icon based on the support result. This allows terminal testers to clearly see the network's support for emergency call capabilities directly on the terminal display, reducing unnecessary testing efforts and avoiding unnecessary bug reports to developers. This saves testers time and the time it takes to find the cause of the bug, thereby accelerating terminal development. Furthermore, users who need to make emergency calls can be prompted to move their physical location or change their carrier's SIM card to verify the functioning of emergency call capabilities, ensuring user safety while improving the user experience.
