In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that this application can be implemented without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

[0041] This application provides a task registration method, apparatus, device, and storage medium, which will be described in detail below.

[0042] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the scenario of the task registration system provided by an embodiment of this application. The task registration system may include a terminal device 100 and a server 200, and the server 200 may transmit data to the terminal device 100. As the terminal device 100 in Figure 1 can perform task registration with the server according to the network signal, so as to execute the task registration method in this application.

[0045] It should be noted that Figure 1 The schematic diagram of the scenario of the task registration system shown is only an example. The task registration system and scenario described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the task registration system and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0046] As Figure 2 shown, Figure 2 This is a schematic flowchart of an embodiment of the task registration method in the embodiments of the present application. The task registration method may include the following steps 201 to 203:

[0047] 201. If the target task registration fails under the current network, detect whether there is permission to roam the mobile network.

[0048] In an embodiment of the present application, the target task may be IMS task registration. In some cases, if there are problems such as network fluctuations or failures in the device's current primary network, such as Home PLMN, it will cause the IMS task registration to fail. At this time, the device will be in a long-term no-service state. Therefore, it is possible to detect whether the device has roaming permission, and then use the roaming network to restore the device's connection to the server.

[0049] Among them, determining whether the device has roaming permission can be determined according to the service activation status of the operator. For example, the device can send a roaming network usage request to the operator network. If the operator feedbacks a rejection message, it can be determined that the device does not have the permission to roam the mobile network. Specifically, the present application does not limit the specific detection method.

[0050] 202. If there is permission to roam the mobile network, determine the target roaming mobile network.

[0051] In the embodiments of the present application, if it is determined that the device has the permission to roam on the mobile network, the optimal target roaming mobile network can be determined according to each roaming network provided by the operator's base station. Among them, each roaming mobile network provided by the current base station can be filtered according to the signal strength, so as to filter out the target roaming mobile network with the best signal. Or, the roaming mobile network automatically assigned by the base station can be used as the target roaming mobile network. Specifically, the embodiments of the present application do not limit the specific scheme for determining the target roaming mobile network.

[0052] 203. Register the target task according to the target roaming mobile network.

[0053] After successfully connecting to the target roaming mobile network, the IMS task can be registered according to the normal IMS task registration process. Among them, the IMS task registration process can refer to any technical solution, and the embodiments of the present application do not limit it.

[0054] The task registration method provided by the present application can detect whether the device has the permission to roam on the mobile network when the target task registration fails under the current network. If the device has the permission to roam on the mobile network, an optimal target roaming mobile network can be determined, and the target task can be re-registered through the target roaming mobile network, avoiding the problem of the device being without service for a long time.

[0055] In order to better implement the embodiments of the present application, in one embodiment of the present application, if the device has the permission to roam on the mobile network, determining the target roaming mobile network includes:

[0056] If the device has the permission to roam on the mobile network, obtain multiple roaming mobile networks; determine the target roaming mobile network according to the current signal strength, current network load and historical connection success rate corresponding to each roaming mobile network.

[0057] In order to increase the stability of using the roaming mobile network, the embodiments of the present application also provide a better solution for determining a better target roaming mobile network.

[0058] Specifically, if the device has the permission to roam on the mobile network, then when determining the target roaming mobile network from each roaming mobile network, the scheme can not only combine the current signal strength, but also combine the current network load and historical connection success rate of the roaming mobile network to determine the target roaming mobile network.

[0059] Optionally, the first roaming mobile network with a signal strength greater than the signal strength threshold can be determined according to the current signal strength corresponding to each roaming mobile network first; then, from the first roaming mobile networks, the second roaming mobile network with a current network load less than the target load threshold can be determined; finally, from the second roaming mobile networks, the roaming mobile network with the highest historical connection success rate can be determined as the target roaming mobile network. Of course, it is also possible to first screen according to the current network load, then screen according to the historical connection success rate, and then determine the final target roaming mobile network according to the current signal strength. Therefore, this application does not limit the order of determination of the current signal strength, the current network load, and the historical connection success rate.

[0060] In order to better implement the embodiments of the present application, in one embodiment of the present application, after detecting whether there is a permission for the roaming mobile network, the method further includes:

[0061] If there is no permission for the roaming mobile network, detect the wireless network in the current environment to determine the target wireless network; register the target task according to the target wireless network.

[0062] The above embodiments provide a solution for re-registering the target task through the roaming mobile network. However, in some application scenarios, the user may not have the roaming permission enabled. Therefore, when detecting the permission of the roaming mobile network, a detection result of no roaming permission may be obtained. If the user does not have the roaming permission enabled, the roaming mobile network provided by the operator cannot be used. At this time, the IMS task registration can also be considered according to the wireless wifi network.

[0063] Specifically, if it is determined that the device does not have the permission for the roaming mobile network, it is possible to detect whether there is a target wireless network that has been successfully connected historically in the environment where the device is currently located. If there is such a target wireless network, the device can automatically connect to the target wireless network. After successfully connecting to the target wireless network, the IMS task can be registered according to the target wireless network.

[0064] In order to better implement the embodiments of the present application, in one embodiment of the present application, the method further includes:

[0065] Monitor the network status of each roaming mobile network and the wireless network in the current environment; if the network status of each roaming mobile network and the wireless network in the current environment is in an unavailable state, switch to the emergency mode.

[0066] In the above embodiments, a solution for task registration based on a roaming mobile network or a wireless network is provided. However, in some scenarios, after the wireless network is successfully connected, there may be a situation where the wireless network cannot access the Internet, or after the roaming mobile network is connected, the user is in an overdue state, resulting in the inability to use the corresponding network. To avoid the loss of the basic communication function of the user due to the unavailable network, in the embodiments of the present application, if it is detected that both the wireless network and the roaming mobile network are unavailable, the device can be switched to an emergency mode that can make emergency calls.

[0067] It should be noted that in any embodiment of the present application, for example, when switching to a target roaming mobile network or switching to a target wireless network, during the network switching process, the user will generate temporary network data. Therefore, to avoid data loss caused by network switching, in any embodiment of the present application, the temporary data generated by the user can be cached during network switching, and after the network is successfully switched, the temporary data can be synchronized.

[0068] To better implement the embodiments of the present application, in one embodiment of the present application, after the permission of the roaming mobile network is not available, the method further includes:

[0069] If the wireless network is not detected, cache the current temporary data; if the registration of the target task is re-completed under the current network, synchronize the current temporary data.

[0070] The above embodiments provide a solution for task registration using a wireless network when the roaming mobile network permission is not available. However, there are still some situations, that is, in the current environment where the device is located, there is no target wireless network. At this time, the device is in a no-service state, and the device is still generating temporary data that requires services according to the user's operations. Therefore, to avoid data loss of the user in the no-service state, the temporary data generated by the user during this period can also be cached. If the current network is restored and the registration of the IMS task is re-completed under the current network, the temporary data generated during the no-service period can be synchronized at this time, so as to avoid the problem of user data loss.

[0071] Among them, the current temporary data can be cached in the target storage area. When the data is synchronized, feedback to the operator server or after the interaction is completed, the target storage area can be emptied to avoid the occupation of storage space by temporary data.

[0072] To better implement the embodiments of the present application, in one embodiment of the present application, detecting the wireless network in the current environment and determining the target wireless network includes:

[0073] Detect the wireless networks in the current environment, and determine the historical success rate and the current signal strength corresponding to each wireless network; determine the target wireless network according to the historical success rate and the current signal strength corresponding to each wireless network.

[0074] In the above embodiments, a solution for re-registering the target task according to the target wireless network is provided. However, in some scenarios, there are multiple available wireless networks in the current environment that the user has connected to historically. Therefore, in response to this situation, the embodiments of the present application also provide a solution for determining the target wireless network.

[0075] Optionally, first determine the first wireless networks with a current signal strength greater than the signal strength threshold according to the current signal strength corresponding to each wireless network; then, from the first wireless networks, determine the second wireless networks with a current network load less than the target load threshold; finally, from the second wireless networks, determine the wireless network with the highest historical connection success rate as the target wireless network. Of course, it is also possible to first screen according to the current network load, then screen according to the historical connection success rate, and then determine the final target wireless network according to the current signal strength. Therefore, the present application does not limit the order of determination of the current signal strength, the current network load, and the historical connection success rate.

[0076] To better implement the embodiments of the present application, in one embodiment of the present application, the method further includes:

[0077] When performing network switching and / or target task registration, output a prompt message; the prompt message is used to prompt the user of the current network status and / or a suggestion message.

[0078] In the above embodiments, a solution for re-registering the target task is provided, and network switching is involved at the same time. When switching networks, the current network status can be displayed for the user to autonomously select available networks. If the user does not perform a selection operation, the system can automatically select. In addition, since temporary data generated by the user will be stored when switching networks or re-registering tasks. Therefore, relevant suggestion messages can be appropriately reminded. For example, if the current storage space is insufficient to store too much temporary data, it can be suggested that the user wait until the network is restored before performing the operation task, etc.; or, it can also be combined with the network status. For example: if the network status is poor, it can be suggested that the user operate temporarily, etc. The specific embodiments of the present application are not limited.

[0079] To better implement the task registration method in the embodiments of the present application, on top of the task registration method, the embodiments of the present application also provide a task registration device, as Figure 3 shown, the device 300 includes:

[0082] The registration module 303 is used to register the target task according to the target roaming mobile network.

[0083] The task registration device provided by this application can, if the registration of the target task fails under the current network, the detection module 301 detects whether the device has the permission to roam on the mobile network. If the device has the permission to roam on the mobile network, the determination module 302 can determine an optimal target roaming mobile network, and then the registration module 303 can re-register the target task through the target roaming mobile network, avoiding the problem of the device being without service for a long time.
