[0043] Figure 2 This is a flowchart illustrating another communication method according to an exemplary embodiment.

[0044] Figure 3 This is a block diagram illustrating a communication device according to an exemplary embodiment.

[0045] Figure 4 This is a block diagram of an electronic device according to an exemplary embodiment. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] First, the application scenarios of this disclosure will be described. This disclosure can be applied to mobile communication scenarios. With the continuous development and advancement of mobile communication technologies such as 4G and 5G, most smart terminals can support carrier aggregation (CA) capabilities to provide higher data service rates. However, in related technologies, terminals with carrier aggregation capabilities may experience communication failures in certain specific communication scenarios, such as dropped voice calls.

[0048] For example, with the construction of 5G SA (Stand Alone) networks, since the currently deployed 5G SA networks do not yet support voice services, 5G users' voice services need to fall back to 4G via methods such as EPSFB (Evolved Packet System Fallback) for voice communication. When a terminal falls back from 5G to 4G for a call, due to the change in the terminal's network state, the network device will send a terminal capability query message to the terminal to check the service capabilities supported by the terminal. In related technologies, if the terminal supports carrier aggregation capability, it will report carrier aggregation capability information in the terminal capability message. This carrier aggregation capability information can include the CA combinations supported by the terminal. Thus, the network device can add CA carriers to the terminal based on the CA combinations reported by the terminal. CA technology refers to aggregating 2 to 5 LTE member carriers together. Once the terminal successfully adds these carriers, it can achieve a maximum transmission bandwidth of 100MHz, meaning the terminal can then access what is commonly referred to as the 4G+ network, thereby increasing data rates and improving the peak rate experience for terminal users. However, during the process of adding a CA carrier to a terminal by network equipment, various reasons can cause the CA carrier addition to fail. If the CA carrier addition fails during voice communication at the terminal, it will affect the voice communication quality. In severe cases, it may even interrupt the wireless communication link between the terminal and the network equipment, directly leading to call failure and seriously affecting the user experience. In addition, even if the CA is added successfully, there will still be some signaling overhead and power consumption issues, which will have a certain impact on the terminal's voice communication performance.

[0049] To address the aforementioned issues, this disclosure provides a communication method, apparatus, storage medium, and electronic device. After receiving a terminal capability query message from a network device, the terminal can, based on its current communication scenario, choose not to send carrier aggregation capability information to the network device. This avoids communication failures caused by the carrier aggregation capability information in the current communication scenario.

[0050] The present disclosure will now be described in conjunction with specific embodiments.

[0051] Figure 1 This is a communication method illustrated according to an exemplary embodiment, such as... Figure 1 As shown, the execution subject of this method can be a terminal, and the method can include:

[0052] S101, Receive terminal capability query message sent by network device.

[0053] S102. Determine whether the current communication scenario of the terminal is the preset communication scenario.

[0054] S103. If the current communication scenario is a preset communication scenario, send a terminal capability message that does not contain carrier aggregation capability information to the network device.

[0055] The communication scenario can be the communication state of the terminal, such as voice communication scenario (indicating that the terminal is making a voice call), high-volume data communication scenario (indicating that the terminal is performing data services with high traffic demand such as file downloading and video playback), low-volume data communication scenario (indicating that the terminal is performing data services with low traffic demand such as real-time communication), and idle scenario (indicating that the terminal is not performing any communication services).

[0056] For example, the current communication scenario could be a voice communication scenario or a low-volume data communication scenario. In these scenarios, the terminal's data traffic demand is relatively low, therefore, it is not necessary to enable the terminal's carrier aggregation capability. By sending a terminal capability message to the network device that does not contain carrier aggregation capability information, the terminal can make the network device believe that the terminal does not have carrier aggregation capability. Therefore, the terminal's carrier aggregation capability will not be enabled, which reduces the signaling or service interactions required to enable carrier aggregation capability. This avoids communication failures caused by signaling or service interactions and does not degrade the performance of the terminal's current voice or low-volume data communication.

[0057] Using the above method, a terminal capability query message sent by a network device is received; it is determined whether the terminal's current communication scenario is a preset communication scenario; if the current communication scenario is a preset communication scenario, a terminal capability message without carrier aggregation capability information is sent to the network device. In this way, by not sending the carrier aggregation capability information to the network device, communication failures caused by the network device performing corresponding signaling or service interactions based on the carrier aggregation capability information can be avoided.

[0058] Furthermore, the step S102 above, which determines whether the terminal's current communication scenario is a preset communication scenario, may include one or more of the following methods:

[0059] Method 1: Obtain the scene discrimination parameters of the terminal; if the scene discrimination parameters are the preset scene parameters, determine that the current communication scene of the terminal is the preset communication scene.

[0060] For example, the scene discrimination parameters can be obtained through the following steps:

[0061] First, upon receiving a voice call command, monitor the network status of the terminal.

[0062] The voice call instruction can be a calling instruction initiated by the user through the terminal (e.g., a calling instruction triggered by the user making a voice dialing through the terminal), or a voice paging instruction received by the terminal as the called party.

[0063] Then, based on the network status of the terminal, the scene discrimination parameters of the terminal are determined.

[0064] For example, if the network status of the terminal changes from occupying the first network to occupying the second network, the scene discrimination parameter of the terminal is determined to be the preset scene parameter.

[0065] The first network can be a network that does not support voice communication, such as a 5G or 6G network that does not support voice communication. In the early stages of 5G network construction, only data service communication capabilities may be provided, and core network equipment related to voice may not be deployed. Therefore, this 5G network may not support voice communication.

[0066] It should be noted that after determining that the scene discrimination parameter of the terminal is the preset scene parameter, the scene discrimination parameter can be stored in the terminal's memory so that the terminal can retrieve the scene discrimination parameter when needed and determine whether the terminal's current communication scene is the preset communication scene based on the scene discrimination parameter.

[0067] Method 2: If it is determined that the terminal reselects from the first network or switches to the second network for voice communication, the current communication scenario of the terminal is determined to be the preset communication scenario.

[0068] For example, the following steps can be used to determine whether the terminal reselects or switches from the first network to the second network for voice communication:

[0069] First, upon receiving a voice call command, determine whether the terminal is currently registered on the first network.

[0070] Similarly, the voice call command can be a calling command initiated by a user through the terminal (e.g., a calling command triggered by a user making a voice dialing through the terminal), or a voice paging command received by the terminal as the called party. The first network can be a network that does not support voice communication, such as a 5G or 6G network that does not support voice communication. In the early stages of 5G network deployment, only data service communication capabilities may be provided, and voice-related core network equipment may not be deployed; therefore, the 5G network may not support voice communication.

[0071] Secondly, if the terminal is currently residing on the first network, it can reselect or switch to the second network to make a voice call.

[0072] The second network is a network that supports voice communication, such as a 4G network, a 3G network, or a 2G network that supports voice communication.

[0073] Finally, during the voice call process, it is determined that the terminal will reselect or switch from the first network to the second network for voice communication.

[0074] For example, if the first network is a 5G network and the second network is a 4G network, the terminal can reselect to the 4G network and make a voice call using EPSFB (Electronic Shared Fallback). When the terminal is camped on a 5G network that does not support voice communication, it will initiate EPSFB upon receiving a voice call command. This involves using fallback technology to transfer the voice communication service to the corresponding 4G network for processing. This process may include: the 5G network device sending a blind redirection message; the terminal determining the 4G serving cell to which it can fall back based on the received blind redirection message; and establishing a communication service based on that 4G serving cell. The blind redirection message can be a Radio Resource Control Release (RRCRelease) message, which may carry a specific target cell frequency to instruct the terminal to fall back to that target cell frequency for communication. Thus, when the terminal falls back to the 4G network for a voice call, it can be determined whether the terminal has reselected from the first network or switched to the second network for voice communication.

[0075] In this way, if a terminal capability query message is received from the network device during the current voice communication, it can be determined that the current communication scenario of the terminal is the preset communication scenario. This allows the terminal capability message that does not contain the carrier aggregation capability information to be sent to the network device, thus avoiding voice communication drops caused by the network device performing corresponding signaling or service interactions based on the carrier aggregation capability information. Additionally, it saves signaling overhead, reduces terminal power consumption, and improves the terminal's voice communication performance.

[0076] Method 3: If it is determined that the terminal is conducting voice communication through the second network, the current communication scenario of the terminal is determined to be the preset communication scenario.

[0077] For example, the second network is a network that supports voice communication. For instance, the second network can be a 4G network that supports HD voice, a 3G network that supports regular voice, or a 2G network.

[0078] Upon receiving a voice call command, if it is determined that the terminal is currently camped on the second network, voice communication can be directly conducted through the second network. In this case, the terminal's current communication scenario can be determined to be the preset communication scenario. This allows the network device to send a terminal capability message that does not contain carrier aggregation capability information, thereby avoiding voice communication drops caused by the network device performing corresponding signaling or service interactions based on the carrier aggregation capability information.

[0079] Furthermore, when the terminal reselects or switches from the first network to the second network for voice communication, or when the terminal directly conducts voice communication through the second network, upon the termination of the voice communication (e.g., upon receiving a voice call termination command, or when the voice communication link is released for specific reasons), the terminal's current communication scenario can be changed to a voice call termination state. At this time, the terminal can proactively send a new terminal capability message containing the aforementioned carrier aggregation capability information to the network device, enabling the network device and the terminal to perform signaling and / or service interactions corresponding to the aforementioned carrier aggregation capability information, thereby improving the terminal's communication service performance.

[0080] In another embodiment of this disclosure, if the terminal's current communication scenario is a preset communication scenario, and if it has not received a terminal capability query message sent by the network device, and the terminal has previously sent a terminal capability message containing carrier aggregation capability information to the network device, it can proactively send a terminal capability message that does not contain the carrier aggregation capability information to the network device.

[0081] It should be noted that since network devices do not need to obtain terminal capability information every time a service is performed, for example, they can obtain complete terminal capability information once by sending a terminal capability query message during terminal registration. Afterward, unless the terminal re-registers, this terminal capability information will be used for communication services. Thus, using this embodiment, if the terminal does not receive a terminal capability query message from the network device after the current communication scenario changes (e.g., within a preset time period after the current communication scenario changes to a preset communication scenario), the terminal proactively sends a terminal capability message to the network device that does not contain the carrier aggregation capability information. This allows the network device to update the terminal's terminal capability information, avoiding communication failures caused by the network device performing corresponding signaling or service interactions based on the carrier aggregation capability information.

[0082] Figure 2 This is another communication method illustrated according to an exemplary embodiment, such as Figure 2 As shown, the method may include:

[0083] S201. Upon receiving a voice call command, monitor the network status of the terminal.

[0084] The voice call instruction can be a calling instruction received by the terminal as the caller, initiated by the user through the terminal, or a voice paging instruction received by the terminal as the called party.

[0085] For example, the terminal may include a call monitoring module and a network monitoring module. In this step, the call monitoring module can determine whether a voice call command has been received. If a voice call command has been received, it is determined that the terminal is in a call and the network monitoring module can be notified to start. The network monitoring module can monitor the network status of the terminal and confirm whether the terminal has undergone network reselection or switching.

[0086] S202. Determine the scene discrimination parameters of the terminal based on the network status of the terminal.

[0087] Specifically, if the scenario discrimination parameter is a preset scenario parameter, it indicates that the terminal's current communication scenario is a preset communication scenario; conversely, if the scenario discrimination parameter is not a preset scenario parameter, it indicates that the terminal's current communication scenario is not the aforementioned preset communication scenario. The preset communication scenario can include one or more. As long as the current communication scenario is any one of multiple preset communication scenarios, the scenario discrimination parameter can be determined to be a preset scenario parameter. The preset communication scenario can include a scenario where the terminal reselects or switches from a first network to a second network for voice calls. That is, if the terminal reselects or switches from the first network to the second network for voice calls, the terminal's scenario discrimination parameter can be determined to be a preset scenario parameter. The first network can be a 5G network, 6G network, or Wi-Fi network that does not support voice communication, and the second network can be a 4G network, 3G network, or 2G network that supports voice communication.

[0088] For example, the terminal may further include a scenario list module, which can be used to store the aforementioned preset communication scenarios. In this step, if the terminal's network monitoring module detects that the terminal reselects or switches from the first network to the second network for a voice call, it can determine that the terminal's current communication scenario is a preset communication scenario stored in the scenario list module, and set the scenario discrimination parameter to the preset scenario parameter. The network monitoring module can store the scenario discrimination parameter so that other modules of the terminal can obtain it.

[0089] S203. If a terminal capability query message is received from a network device, the scenario discrimination parameters of the terminal are obtained.

[0090] S204. If the scenario discrimination parameter is the preset scenario parameter, send a terminal capability message that does not contain carrier aggregation capability information to the network device.

[0091] Specifically, if the scenario discrimination parameter is a preset scenario parameter, the current communication scenario of the terminal can be determined to be a preset communication scenario. In this case, a terminal capability message without carrier aggregation capability information can be sent to the network device. Conversely, if the scenario discrimination parameter is not a preset scenario parameter, that is, if the current communication scenario is not a preset communication scenario, a complete terminal capability message containing carrier aggregation capability information can be sent.

[0092] For example, the terminal may further include a terminal capability determination module, which can perform steps S203 and S204 as described above. If the terminal capability determination module receives a terminal capability query message sent by the network device, it can obtain the terminal's scenario determination parameters from the network monitoring module. If the scenario determination parameters are preset scenario parameters, it can send a terminal capability message to the network device that does not contain carrier aggregation capability information corresponding to the preset communication scenario. Conversely, if the scenario determination parameters are not preset scenario parameters, it can send a complete terminal capability message that includes carrier aggregation capability information.

[0093] In this way, when a terminal falls back from a 5G network to a 4G network for voice calls, the terminal's CA capability can be ignored, thus avoiding dropped voice calls, improving voice communication performance, and reducing signaling overhead and power consumption.

[0103] Optionally, the scenario determination module 302 is configured to determine the current communication scenario of the terminal as the preset communication scenario when it is determined that the terminal is conducting voice communication through the second network.
