Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a control method, apparatus, terminal device and storage medium for a network search mode. Background Technology

[0002] Regarding the search and selection of available networks, the terminal device provides users with two network search modes: manual network search and automatic network search. The default mode is automatic network search, which means that the optimal network is automatically selected according to the protocol based on the actual network conditions. Manual network search allows users to select a specified operator's network for internet access according to their own expectations, but it is very likely that the selected network conditions will be poor and the user will be in a state of network outage for a long time.

[0003] The terminal device also provides an optimized solution for automatically searching for a network based on network status after a manual network search. This solution aims to ensure a good internet experience for users when a manual network search fails. However, this solution does not consider other aspects of the user experience, such as pricing, regional differences, and variations in operator behavior. Therefore, the existing network search mode still has some shortcomings and urgently needs optimization. Summary of the Invention

[0008] When it is determined that the terminal device has entered roaming status, it is monitored whether the terminal device meets the automatic network search conditions in the current roaming area;

[0009] When it is determined that the terminal device meets the automatic network search conditions, the network search mode of the terminal device is switched to automatic network search mode;

[0010] When it is determined that the terminal device does not meet the automatic network search conditions, the network search mode of the terminal device is switched to manual network search mode.

[0011] Secondly, a control device for a network search mode is provided, including:

[0014] The control unit is used to switch the network search mode of the terminal device to automatic network search mode when it determines that the terminal device meets the automatic network search conditions.

[0015] The control unit is further configured to switch the network search mode of the terminal device to manual network search mode when it determines that the terminal device does not meet the automatic network search conditions.

[0016] Thirdly, a terminal device is provided, comprising: a processor and a memory configured to store a computer program capable of running on the processor.

[0017] Wherein, the processor is configured to execute the steps of the aforementioned method when running the computer program.

[0018] Fourthly, a computer-readable storage medium is provided having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the aforementioned method.

[0019] This application provides a method, apparatus, terminal device, and storage medium for controlling network search mode. The method includes: monitoring whether the terminal device has entered roaming mode; when it is determined that the terminal device has entered roaming mode, monitoring whether the terminal device meets the automatic network search conditions; when it is determined that the terminal device meets the automatic network search conditions, switching the network search mode of the terminal device to automatic network search mode; and when it is determined that the terminal device does not meet the automatic network search conditions, switching the network search mode of the terminal device to manual network search mode.

The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0027] Figure 1 This is a schematic diagram illustrating an application scenario of an embodiment of this application. For example... Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0028] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto.

[0029] exist Figure 1 In the communication system 100 shown, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0031] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

[0038] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0039] Figure 2 This is a first flowchart illustrating the control method for the network search mode in this application embodiment, as shown below. Figure 2 As shown, the method may specifically include:

[0040] Step 201: Monitor whether the terminal device has entered roaming mode;

[0041] It should be noted that when a terminal device moves from city A to city B, if the terminal device's network location is city A, that is, the terminal device leaves the coverage area of ​​operator network A in city A and enters the coverage area of ​​operator network B in city B, the terminal device enters roaming status.

[0042] In some embodiments, the terminal device obtains Subscriber Identity Module (SIM) information and network information of the current roaming area; based on the SIM card information and network information, it determines whether the user has entered a roaming state. For example, the terminal determines whether it has entered a roaming state by obtaining the Public Land Mobile Network (PLMN) of the operator network in the roaming area and the Home Public Land Mobile Network (HPLMN) of the terminal device. It should be noted that operator network A and operator network B can be provided by the same operator or by different operators. Different operator networks have different PLMN numbers. Here, PLMN = MCC + MNC, where MCC uniquely identifies the country or region to which the mobile user belongs, and MNC identifies different operator networks in the same region. If the operator network PLMN and HPLMN currently obtained by the terminal device are not simultaneously determined to be in a roaming state, and if they are the same, it is determined that the user has not entered a roaming state.

[0043] Step 202: When it is determined that the terminal device has entered roaming status, monitor whether the terminal device meets the automatic network search conditions in the current roaming area; if yes, proceed to step 203; if no, proceed to step 204.

[0044] It should be noted that the automatic network search condition is a trigger condition for automatically searching the operator's network in the current roaming area. Based on the operator's network information in the current area, it is determined whether the terminal device meets the automatic network search condition in the current roaming area. When the terminal device enters roaming state and meets the automatic network search condition, the terminal device is controlled to enter the automatic network search mode; when the terminal device enters roaming state but does not meet the automatic network search condition, the terminal device is controlled to enter the manual network search mode.

[0045] In some embodiments, the roaming scenario of the terminal device is determined based on the operator network information of the current area. If the terminal device is in a first roaming scenario, it is determined that the automatic search conditions are met; if the terminal device is in a second roaming scenario, it is determined that the automatic search conditions are not met. It is understood that the automatic network search conditions include: the terminal device is in a first roaming scenario; wherein, in the first roaming scenario, the terminal device is allowed to automatically search for the operator network in the current roaming area. It should be noted that roaming scenarios can be divided according to the country (or region) and operator network configuration to obtain a first roaming scenario that allows automatic network search and a second roaming scenario that does not allow automatic network search.

[0046] It should also be noted that the first roaming scene can be at least one roaming scene obtained according to at least one segmentation strategy. The second roaming scene can be any other roaming scene besides the first roaming scene.

[0047] In some embodiments, considering the impact of roaming charges, the first roaming scenario can be a roaming scenario where the target operator network in the current roaming area has no roaming charges. The first roaming scenario can also be a roaming scenario where the terminal device subscribes to roaming services of the target operator network in the current roaming area. Accordingly, monitoring whether the terminal device meets the automatic network search conditions in the current roaming area includes: monitoring whether there is a target operator network in the current roaming area that provides free roaming services to the terminal device, and determining whether the automatic network search conditions are met; or, monitoring whether there is a target operator network in the current roaming area for which the terminal device has subscribed to roaming services, and determining whether the automatic network search conditions are met. It should be noted that the target operator network can be one or more operator networks in the current roaming area, and the target operator and the home operator can be the same operator or different operators.

[0048] For example, when a terminal device moves from city A to city B, if the terminal device's network home location is city A, that is, the terminal device leaves the coverage area of ​​operator network A in city A and enters the coverage area of ​​operator network B in city B, and operator network B provides it with free roaming service, or the terminal device has pre-subscribed to the roaming service of operator network B, then the roaming scenario of the terminal device from city A to city B is the first roaming scenario.

[0049] In some embodiments, considering the operator's network configuration, the first roaming scenario can be divided based on country (or region) or operator network coverage. For example, the first roaming scenario includes a domestic roaming scenario; specifically, it refers to a scenario where the terminal device can use mobile communication services when it leaves the city where its home network is located and travels to another city within the same country or region. Monitoring whether the terminal device meets the automatic network search conditions in the current roaming area includes: obtaining the public land mobile network (PRM) of the operator's network in the current roaming area of ​​the terminal device; if the country code of the PRM in the roaming area is the same as the country code of the PRM in the terminal device's home location, the terminal device is determined to be in a domestic roaming scenario; if the country code of the PRM in the roaming area is different from the country code of the PRM in the terminal device's home location, the terminal device is determined to be in an international roaming scenario.

[0050] In some embodiments, the first roaming scenario includes domestic roaming, and the operator network in the current roaming area has no roaming charges. In other embodiments, the first roaming scenario includes domestic roaming, and the terminal device subscribes to roaming services of the operator network in the current roaming area. When multiple operators exist in a country or region, and the operator networks have coverage blind spots, the network search mode control method provided in this application can provide domestic roaming users with reasonable and efficient network search services, reduce roaming charges caused by automatic network search, avoid users frequently performing manual network searches, and improve network search efficiency.

[0051] In some embodiments, the first roaming scenario may include an international roaming scenario, where the operator network in the current roaming area has no roaming charges. In other embodiments, the first roaming scenario includes an international roaming scenario, where the terminal device subscribes to the roaming service of the operator network in the current roaming area. Specifically, an international roaming scenario may involve the terminal device leaving the country or region where the network is located to travel to another country or region, where the operator network in the current roaming area provides free roaming service, or the terminal device subscribing to the roaming service of the operator network in the current roaming area in advance. For terminal devices that frequently move between two countries, the control method for the network search mode provided in this application embodiment can provide them with efficient network search services, reduce roaming charges caused by automatic network search, avoid users frequently performing manual network search, and improve network search efficiency.

[0052] In some embodiments, the method further includes: when determining that the terminal device has entered roaming status, obtaining operator network information of the target operator network in the current roaming area; determining, based on the operator network information, whether the target operator network in the current roaming area has enabled intelligent handover functionality; if the target operator network in the current roaming area has enabled intelligent handover functionality, determining that the automatic search conditions are met; if the target operator network in the current roaming area has not enabled intelligent handover functionality, determining that the automatic search conditions are not met. It is understood that the automatic network search conditions also include: the target operator network in the current roaming area has enabled intelligent handover functionality.

[0053] It should be noted that the operator network information may include a smart handover identifier for the current roaming area or operator network, used to indicate whether the smart handover function is enabled in the current roaming area or operator network. For example, a smart handover identifier of TRUE indicates that the smart handover function is enabled, and FALSE indicates that the smart handover function is disabled. Different roaming areas or different operator networks can configure whether to enable the smart handover function provided in this application embodiment through the smart handover identifier. In some embodiments, the smart handover identifier of the current roaming area sent by the network device is obtained; or the smart handover identifier of the current roaming area is obtained from a local cache unit.

[0054] Step 203: When it is determined that the terminal device meets the conditions for automatic network search, switch the network search mode of the terminal device to automatic network search mode;

[0055] It should be noted that if the current network search mode is automatic network search mode, then when it is determined that the terminal device meets the conditions for automatic network search, the automatic network search mode will be maintained, and automatic network search will be performed on the current roaming area. If the current network search mode is manual network search mode, then when it is determined that the terminal device meets the conditions for automatic network search, the mode will be switched from manual network search mode to automatic network search mode, and automatic network search will be performed on the current roaming area.

[0056] Step 204: If the terminal device does not meet the conditions for automatic network search, switch the terminal device's network search mode to manual network search mode.

[0057] It should be noted that if the current network search mode is automatic, it will switch to manual network search mode if the terminal device does not meet the conditions for automatic network search. If the current network search mode is manual, it will remain in manual network search mode if the terminal device does not meet the conditions for automatic network search.

[0058] In some embodiments, the method further includes: when it is determined that the terminal device does not meet the conditions for automatic network search, generating a manual network search prompt message to prompt the user that the current network connection is disconnected and to perform a manual network search, so as to avoid being in a network outage state for a long time and affecting network services.

[0059] In some embodiments, the method further includes: disconnecting the network connection when it is determined that the terminal device has entered roaming mode and the terminal device does not meet the automatic network search conditions. It should be noted that if the terminal device enters roaming mode and the current roaming area does not meet the automatic network search conditions, the network connection is disconnected to avoid incurring additional roaming charges.

[0060] By adopting the above technical solution, automatic network search conditions are set for different roaming scenarios, realizing a scenario-based intelligent switching solution for network search modes. This not only meets the network connection needs of terminal devices in roaming mode, but also takes into account other needs such as tariffs and operator network configuration, thereby improving the quality of Internet access services for terminal devices in roaming mode.

[0061] Figure 3 This is a second flowchart illustrating the control method for the network search mode in an embodiment of this application, as shown below. Figure 3 As shown, the method may specifically include:

[0062] Step 301: When the terminal device is in manual network search mode, monitor whether the terminal device has entered roaming mode; if not, proceed to step 302; if yes, proceed to step 303.

[0063] Step 302: When it is determined that the terminal device has not entered roaming mode, switch to automatic network search mode.

[0064] In some embodiments, when it is determined that the terminal device is not in roaming mode but is detected to be in a network-disconnected state, the terminal device's network search mode is switched to automatic network search mode. It should be noted that if the current network search mode is automatic, it will remain in automatic mode when the terminal device is detected to be in a network-disconnected state. If the current network search mode is manual, it will switch from manual to automatic mode when the terminal device is detected to be in a network-disconnected state, to avoid the terminal being in a network-disconnected state for an extended period.

[0065] Step 303: When it is determined that the terminal device has entered roaming state, monitor whether the terminal device is in the first roaming scenario; if not, proceed to step 304; if yes, proceed to step 305.

[0066] Step 304: When the terminal device is in the second roaming scenario, maintain the manual network search mode.

[0067] Step 305: When the terminal device is in the first roaming scenario, monitor whether the target operator network in the current roaming area has enabled the intelligent handover function; if not, proceed to step 307; if yes, proceed to step 306.

[0068] It should be noted that the smart handover function may be enabled or disabled for all carrier networks in the current roaming area, or for some carrier networks in the current roaming area.

[0069] Step 306: If the target operator's network in the current roaming area has the intelligent switching function enabled, switch the terminal device's network search mode to automatic network search mode;

[0070] In some embodiments, the method further includes: automatically searching for an optimal network in the target operator network of the current roaming area and registering with the optimal network.

[0071] Step 307: If the target operator's network in the current roaming area does not have the smart switching function enabled, keep the manual network search mode.

[0072] It should be noted that the first roaming scenario can be a roaming scenario where the target operator's network in the current roaming area has no roaming charges, while the second roaming scenario can be a roaming scenario where all operator networks in the current roaming area have roaming charges. The first roaming scenario can also be a roaming scenario where the terminal device subscribes to roaming services of the target operator's network in the current roaming area, while the second roaming scenario can be a roaming scenario where the terminal device does not subscribe to roaming services of all operator networks in the current roaming area.

[0073] In some embodiments, the first roaming scenario is a domestic roaming scenario, and there are no roaming charges in the domestic roaming scenario. The second roaming scenario is an international roaming scenario, and there are roaming charges in the international roaming scenario.

[0074] By adopting the above technical solution, network search scenarios are divided into international roaming scenarios and domestic roaming scenarios. Automatic network search conditions can be set based on information such as tariffs and operator network configurations. When a manual network search results in a network drop due to roaming, the automatic network search mode is only triggered if the automatic network search conditions are met. This achieves a scenario-based intelligent switching solution for network search modes, satisfying the network connectivity needs of terminal devices while also considering other factors such as tariffs and operator network configurations, thereby improving the quality of internet service for terminal devices while roaming.

[0075] Figure 4 This is a schematic diagram of the third process of the control method for the network search mode in the embodiments of this application, as shown below. Figure 4 As shown, the method may specifically include:

[0076] Step 401: When the terminal device is in automatic network search mode, monitor whether the terminal device has entered roaming state; if not, proceed to step 402; if yes, proceed to step 403.

[0077] Step 402: When it is determined that the terminal device has not entered roaming mode, maintain the automatic network search mode.

[0078] Step 403: When it is determined that the terminal device has entered roaming state, monitor whether the terminal device is in the first roaming scenario; if yes, proceed to step 404; if no, proceed to step 405.

[0079] Step 404: When the terminal device is in the first roaming scenario, maintain the automatic network search mode;

[0080] Step 405: When it is determined that the terminal device is not in the first roaming scenario, switch the terminal device's network search mode to manual network search mode.

[0081] In some embodiments, the first roaming scenario is a domestic roaming scenario, and there are no roaming charges in the domestic roaming scenario. The second roaming scenario is an international roaming scenario, and there are roaming charges in the international roaming scenario.

[0082] By adopting the above technical solution, the network search scenario is divided into international roaming scenario and domestic roaming scenario. Automatic network search conditions can be set according to information such as tariffs and operator network configuration. When the network is lost due to roaming during automatic network search, the automatic network search mode will continue if the automatic network search conditions are met, and will switch to manual network search mode if they are not met, thereby reducing unnecessary roaming charges.

[0083] This application also provides a control device for network search mode, applied to terminal devices. Figure 5 This is a schematic diagram of the structural composition of the control device for the network search mode provided in the embodiments of this application, as shown below. Figure 5 As shown, the control device 50 for the network search mode includes:

[0084] Monitoring unit 501 is used to monitor whether the terminal device has entered roaming mode;

[0085] The monitoring unit 501 is also used to monitor whether the terminal device meets the automatic network search conditions in the current roaming area when it is determined that the terminal device has entered the roaming state.

[0086] The control unit 502 is used to switch the network search mode of the terminal device to automatic network search mode when it determines that the terminal device meets the automatic network search conditions.

[0087] The control unit 502 is also used to switch the network search mode of the terminal device to the manual network search mode when it is determined that the terminal device does not meet the conditions for automatic network search.

[0088] In some embodiments, the monitoring unit 501 is used to monitor SIM card information and network information. Based on the SIM card information and network information, it determines whether the terminal device has entered roaming mode and whether the conditions for automatic network search are met.

[0089] In some embodiments, the automatic network search conditions include: the terminal device is in a first roaming scenario; wherein, in the first roaming scenario, the terminal device is allowed to automatically search for the target operator's network in the current roaming area.

[0090] In some embodiments, the first roaming scenario includes the target operator network in the current roaming area providing free roaming services to the terminal device; or, the first roaming scenario includes the terminal device subscribing to roaming services of the target operator network in the current roaming area.

[0091] In some embodiments, the first roaming scenario includes a domestic roaming scenario;

[0092] The monitoring unit 501 is used to obtain the public land mobile network of the operator network in the current roaming area of ​​the terminal device; when the mobile country code of the public land mobile network in the roaming area is the same as the mobile country code of the public land mobile network of the terminal device's home location, it is determined that the terminal device is in a domestic roaming scenario; when the mobile country code of the public land mobile network in the roaming area is different from the mobile country code of the public land mobile network of the terminal device's home location, it is determined that the terminal device is in an international roaming scenario.

[0093] In some embodiments, the automatic network search conditions further include: the target operator network in the current roaming area has enabled the intelligent handover function; the monitoring unit 501 is also used to obtain the operator network information of the target operator network in the current roaming area when it is determined that the terminal device has entered the roaming state; and to determine whether the target operator network in the current roaming area has enabled the intelligent handover function based on the operator network information.

[0094] In some embodiments, the device further includes a network search unit, configured to automatically search for the optimal network in the target operator network of the current roaming area and register with the optimal network when the terminal device meets the automatic network search conditions.

[0095] In some embodiments, the monitoring unit 501 is used to monitor whether the terminal device enters roaming mode when the terminal device is in manual network search mode.

[0096] By using the above-mentioned device, automatic network search conditions can be set for different roaming scenarios, realizing a scenario-based intelligent switching scheme for network search modes. This can not only meet the network connection needs of terminal devices in roaming mode, but also take into account other needs such as tariffs and operator network configuration, thereby improving the quality of Internet access services for terminal devices in roaming mode.
