[0049] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0050] The present application provides a network search method, which includes: performing network search according to an updatable priority list. It can be understood that this network search method can be applied to communication devices that support connections of multiple communication systems, such as smart phones, smart watches, etc. When a communication device needs to use the network, it first searches for the existing base stations around it and performs network search according to the priority list corresponding to each base station. The priority list includes the priorities of each communication system. The communication device will first attempt to connect to the network corresponding to the communication system with a higher priority. After successfully connecting to the network corresponding to a certain communication system, in order to ensure the network quality, the communication device will also perform a re-network search when certain conditions are met. For example, when the residence time on the network corresponding to a certain communication system reaches a preset time, a re-network search will be performed. In the traditional technology, the more advanced network system is often set to a higher priority. However, the popularization degree of the base stations of the more advanced network system is often not high, resulting in some areas not supporting the connection to the network corresponding to the more advanced network system. Therefore, searching for the more advanced network system during each network search or re-network search will increase the additional link data packet delay and radio frequency link power consumption. To solve this problem, the priorities of each network system in the priority list in the present disclosure can be updated according to the actual situation. Please refer to Figure 1 , and the update process of the priority list includes steps S102 to S104.

[0051] S102, when performing network search according to the first priority list, if connected to the network of the first system, keep the first priority list; if connected to the network of the second system, lower the priority of the first system to the priority of the second system to update the current priority list to the second priority list.

[0052] The first priority list includes multiple network systems, and the network search priorities include the first system, the second system, and the third system in descending order. It can be understood that the first priority list is the initial priority list for each base station, such as Figure 2As shown, for ease of explanation, the serial numbers in the list represent the priority levels, with the smaller the serial number, the higher the priority. When setting the first priority list, it can be done according to the advancement degree of each network mode. For example, the advancement degrees of the first mode, the second mode, and the third mode decrease. It can also be set in other ways according to the actual situation for the priorities of each network mode in the first priority list. When searching for a network according to the first priority list, if a network of the first mode is searched and successfully connected, it means that there is a stable base station supporting the first mode in the current area. It makes sense to search for the network signal of the relatively advanced network mode of the first mode first. Therefore, when the communication device re-searches for a network on the connected base station, it will continue to search for a network according to the first priority list, as Figure 2 shown in A1.1.1. However, if a network of the first mode is not searched but a network of the second mode is searched and connected, it means that there is temporarily no stable base station supporting the first mode in the current area (for example, the network of the first mode is occupied or there is no base station transmitting the network signal of the first mode). Searching for the network signal of the first mode first will cause increased power consumption and network latency. Therefore, the network of the first mode is reduced to the same priority as the network of the second mode, as Figure 2 shown in A1.1.2, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the second priority list.

[0053] S104, when searching for a network according to the second priority list, if connected to a network of the first mode, the current priority list is restored to the first priority list; if connected to a network of the second mode, the priority of the first mode is reduced to the priority of the third mode to update the current priority list to the third priority list; if connected to a network of the third mode, the search for the first mode is turned off and the priority of the second mode is reduced to the priority of the third mode to update the current priority list to the fourth priority list.

[0054] For the second priority list, the highest priority is serial number 2. The network of the first mode can be searched first to determine whether the situation of unstable support for the first mode is lifted. If a network of the first mode is searched, it means that the situation of unstable support for the first mode is lifted, and the network of the first mode can be searched most preferentially, and the second priority list is restored to the first priority list, as Figure 3 shown in A1.2.1, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the first priority list. If a network of the first mode is not searched but a network of the second mode is searched and connected, it means that the situation of not supporting the network of the first mode cannot be solved temporarily. Then the priority of the network of the first mode is further reduced to the same priority as the network of the third mode, and the second priority list is updated to the third priority list, as Figure 3As shown in A1.2.2, when the communication device re-searches for a network on the connected base station, it will search for the network according to the third priority list.

[0055] If neither the network of the first radio access technology (RAT) nor the network of the second RAT in the second priority level is found, then the network in the third priority level will be searched. If a network of the third RAT is found and connected, it means that the networks of the second RAT in the current area are not stable, and the possibility that the base station stably supports the network of the first RAT is small. Then, the search for the first RAT will be turned off, and the second RAT will be reduced to the same priority level as the third RAT, and the second priority list will be updated to the fourth priority list, as Figure 3 As shown in A1.2.3, when the communication device re-searches for a network on the connected base station, it will search for the network according to the fourth priority list.

[0056] Based on the network search method in this embodiment, when the communication device searches for a network, it searches for the network according to an updatable priority list. The update of the priority list is based on the actual connection situation of the communication device with each network RAT. In the case that the base station does not support the network of a more advanced RAT, the priority of the network of the more advanced RAT will be reduced or even turned off to reduce the search process for the unsupported more advanced network, thereby reducing network latency and reducing the power consumption of the communication device.

[0057] In one embodiment, the update process of the priority list further includes: when searching for a network according to the third priority list, if a network of the first RAT is connected, the current priority list will be restored to the first priority list; if a network of the second RAT is connected, the third priority list will be maintained; if a network of the third RAT is connected, the search for the network of the first RAT will be turned off and the priority of the second RAT will be reduced to the priority of the third RAT, so as to update the current priority list to the fourth priority list.

[0058] It can be understood that when searching for a network according to the third priority list, the network of the second RAT has the highest priority, so the network of the second RAT will be searched first. If a network of the second RAT is found and connected, the third priority list will remain unchanged, as Figure 4 As shown in A2.1.1, when the communication device re-searches for a network on the connected base station, it will search for the network according to the third priority list.

[0059] If the network in the second priority level is not found, the network in the third priority level will be searched. The network of the first RAT can be searched first to determine whether the situation of unstable support for the first RAT is resolved. If a network of the first RAT is found and connected, it means that the situation of unstable support for the first RAT is resolved, and the network of the first RAT can be searched with the highest priority, and the third priority list will be restored to the first priority list, as Figure 4As shown in A2.1.2, when the communication device re-searches for a network on the connected base station, it will search for a network according to the first priority list. If the network of the first radio access technology is not found, but the network of the third radio access technology is found and connected, it means that the networks of the second radio access technology in the current area are not stable, and the possibility that the base station stably supports the network of the first radio access technology is small. Then, the search for the first radio access technology is turned off, and the priority of the second radio access technology is reduced to the same priority as the third radio access technology, and the third priority list is updated to the fourth priority list, as Figure 4 shown in A2.1.3, when the communication device re-searches for a network on the connected base station, it will search for a network according to the fourth priority list.

[0060] In one embodiment, the first priority list further includes a fourth radio access technology, and the priority of searching for the fourth radio access technology is lower than that of the third radio access technology. That is, the communication device also supports communicating with the network of the fourth radio access technology. When setting the first priority list, if sorted by advancement, the advancement of the network of the fourth radio access technology is lower than that of the network of the third radio access technology. It can also be sorted according to other factors according to the actual situation. In addition, it is worth mentioning that when the first priority list further includes the fourth radio access technology, it should be in Figures 2 to 4 a network of "4. Fourth radio access technology" should be added below the serial number 3 in each priority list. When the first priority list further includes the fourth radio access technology, the update process of the priority list further includes:

[0061] When searching for a network according to the fourth priority list, if connected to the network of the second radio access technology, the current priority list is restored to the second priority list; if connected to the network of the third radio access technology, the search for the network of the second radio access technology is turned off to update the current priority list to the fifth priority list; if connected to the network of the fourth radio access technology, the priorities of the second radio access technology and the third radio access technology are reduced to the priority of the fourth radio access technology to update the current priority list to the sixth priority list.

[0062] It can be understood that the highest priority in the fourth priority list is the network under the priority of serial number 3, including the networks of the second radio access technology and the third radio access technology. The network of the second radio access technology can be searched first to determine whether the situation of unstable support for the second radio access technology is resolved. If the network of the second radio access technology is found and connected, it means that the situation of unstable support for the second radio access technology is resolved, and the priority of the second radio access technology can be restored, and on the basis of the restoration of the priority of the second radio access technology, it is re-tried whether the network of the first radio access technology can be stably supported, that is, the fourth priority list is restored to the second priority list, as Figure 5As shown in A3.1.1, when the communication device re-searches for a network on the connected base station, it will search for a network according to the second priority list. If the network of the second system is not found but the network of the third system is found and connected, it means that the possibility of the base station stably supporting the network of the second system is small. Then, the search for the second system is turned off, and the fourth priority list is updated to the fifth priority list, as Figure 5 shown in A3.1.2, when the communication device re-searches for a network on the connected base station, it will search for a network according to the fifth priority list.

[0063] If the network of the priority No. 3 is not found, the network of the priority No. 4 will be searched, that is, the network of the fourth system will be searched. If the network of the fourth system is found and connected, it means that the networks of the second system and the third system in the current area are not stable. Then, the second system and the third system are reduced to the same priority as the fourth system, and the fourth priority list is updated to the sixth priority list, as Figure 5 shown in A3.1.3, when the communication device re-searches for a network on the connected base station, it will search for a network according to the sixth priority list.

[0064] In one embodiment, since the networks of the third system and the fourth system are already relatively backward networks, when the priority list is updated to the fifth priority list, it means that the communication infrastructure in the current area is relatively backward. When searching for a network according to the fifth priority list, only the connection between the third system and the fourth system needs to be tried.

[0065] In one embodiment, the first priority list further includes a network mode to be retired, and the priority of the network mode to be retired is lower than that of the fourth network mode. That is, the communication device still supports communicating with the network of the network mode to be retired. When setting the first priority list, the advancement degree of the network mode to be retired may be the same as that of one of the second network mode, the third network mode, and the fourth network mode. However, since some advanced communication network modes and backward communication network modes occupy the same frequency band, the relatively backward communication network mode needs to give up communication resources to the advanced communication network mode. Therefore, the relatively backward communication network mode will gradually retire from the network. In a specific embodiment, the network of the first network mode includes the NR network, the network of the second network mode includes the LTE network, the network of the third network mode includes the WCDMA network, the network of the fourth network mode includes the GSM network, and the network of the network mode to be retired includes the TDSCDMA network, the EVDO network, and / or the CDMA network. In this embodiment, the network of the network mode to be retired and the network of the third network mode both belong to the 3G network and have a similar advancement degree. However, since the frequency band occupied by the network mode to be retired is very important for 4G and 5G networks, this part of the frequency band needs to be given up for 4G and 5G, so the network in the network mode to be retired will gradually withdraw from the market. The specific communication network modes of the first network mode, the second network mode, the third network mode, the fourth network mode, and the network mode to be retired may be different from those in this embodiment and may change with the development of communication technologies and the regions where this disclosure is used. It is worth mentioning that when the first priority list further includes the network mode to be retired, Figures 2 to 5 a network of "5. Network mode to be retired" should be added below the serial number 4 in each priority list of

[0066] When searching for a network according to the sixth priority list, if connected to the network of the second network mode, the current priority list is restored to the second priority list; if connected to the network of the third network mode, the current priority list is restored to the fourth priority list; if connected to the network of the fourth network mode, the search for the networks of the second network mode and the third network mode is stopped to update the current priority list to the seventh priority list; if connected to the network mode to be retired, the priorities of the second network mode, the third network mode, and the fourth network mode are reduced to the priority of the network mode to be retired to update the current priority list to the eighth priority list.

[0067] It can be understood that the network with the highest priority in the sixth priority list is the network under the priority of serial number 4, including the networks of the second, third, and fourth systems. The network of the second system can be searched first to determine whether the situation of unstable support for the second system has been resolved. If the network of the second system is searched and connected, it means that the situation of unstable support for the second system has been resolved, and the priority of the second system can be restored. Based on the restored priority of the second system, it can be retried whether the network of the first system can be stably supported, that is, the sixth priority list is restored to the second priority list, as Figure 6 shown in A4.1.1, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the second priority list. If the network of the second system is not searched but the network of the third system is searched and connected, it means that the situation of unstable support for the third system has been resolved, and the priority of the third system can be restored. Based on the restored priority of the third system, it can be retried whether the network of the second system can be stably supported, that is, the sixth priority list is restored to the fourth priority list, as Figure 6 shown in A4.1.2, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the fourth priority list. If the networks of the second and third systems are not searched but the network of the fourth system is searched and connected, it means that the possibility of the base station stably supporting the networks of the second and third systems is small. Then, the searches for the second and third systems are closed, and the sixth priority list is updated to the seventh priority list, as Figure 6 shown in A4.1.3, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the seventh priority list.

[0068] If the network of the priority of serial number 4 is not searched, the network of the priority of serial number 5 will be searched, that is, the network of the system to be retired from the network will be searched. If the network of the system to be retired from the network is searched and connected, it means that the networks of the second, third, and fourth systems in the current area are all unstable. Then, the second, third, and fourth systems are reduced to the same priority as the system to be retired from the network, and the sixth priority list is updated to the eighth priority list, as Figure 6 shown in A4.1.4, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the eighth priority list.

[0069] In one embodiment, since the networks of the fourth system and the system to be retired from the network are already relatively backward networks, when the priority list is updated to the seventh priority list, it means that the communication infrastructure in the current area is relatively backward. When searching for a network according to the seventh priority list, it is only necessary to try to connect between the fourth system and the system to be retired from the network. If it is considered that there are few base stations still supporting the system to be retired from the network, after the network of the fourth system is searched for a preset number of times, the network of the system to be retired from the network can be searched again.

[0070] In one embodiment, the process of updating the priority list further includes: when searching for a network according to the eighth priority list, if connected to a network of the second mode, the current priority list is restored to the second priority list; if connected to a network of the third mode, the current priority list is restored to the fourth priority list; if connected to a network of the fourth mode, the current priority list is restored to the sixth priority list; if connected to a network of the mode to be retired from the network, the search for networks of the second mode, the third mode, and the fourth mode is turned off, so as to update the current priority list to the ninth priority list.

[0071] It can be understood that the network with the highest priority in the eighth priority list is the network under the priority of serial number 5, including the networks of the second mode, the third mode, the fourth mode, and the mode to be retired from the network. The network of the second mode can be searched first to determine whether the unstable support for the second mode is lifted. If the network of the second mode is searched and connected, it means that the unstable support for the second mode is lifted, and the priority of the second mode can be restored, and based on the restored priority of the second mode, it is re-tried whether the network of the first mode can be stably supported, that is, the eighth priority list is restored to the second priority list, as Figure 7 shown in A5.1.1, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the second priority list. If the network of the second mode is not searched but the network of the third mode is searched and connected, it means that the unstable support for the third mode is lifted, and the priority of the third mode can be restored, and based on the restored priority of the third mode, it is re-tried whether the network of the second mode can be stably supported, that is, the eighth priority list is restored to the fourth priority list, as Figure 7 shown in A5.1.2, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the fourth priority list. If the networks of the second mode and the third mode are not searched but the network of the fourth mode is searched and connected, it means that the unstable support for the fourth mode is lifted, and the priority of the fourth mode can be restored, and based on the restored priority of the fourth mode, it is re-tried whether the network of the third mode can be stably supported, that is, the eighth priority list is restored to the sixth priority list, as Figure 7 shown in A5.1.3, so that when the communication device re-searches for a network on the connected base station, it will search for a network according to the sixth priority list. If the networks of the second mode, the third mode, and the fourth mode are not searched but the network of the mode to be retired from the network is searched and connected, it means that the possibility of the base station stably supporting the networks of the second mode, the third mode, and the fourth mode is small, then the search for the second mode, the third mode, and the fourth mode is turned off, and the eighth priority list is updated to the ninth priority list, as Figure 7As shown in A5.1.4, when the communication device re-searches for a network on the connected base station, it will search for the network according to the ninth priority list.

[0072] In one embodiment, the network search method further includes:

[0073] 1) When connected to a network of the first mode and re-searching for a network according to the first priority list, if the communication quality of the first mode does not meet the preset conditions, then determine whether the communication quality of the second mode meets the preset conditions.

[0074] 2) If the communication quality of the second mode meets the preset conditions, then connect to the network of the second mode.

[0075] It can be understood that generally, communicating using the network of the first mode will be better than other networks with lower priorities. However, in some special cases, the network of the first mode may fluctuate, resulting in a large network delay, etc. To ensure the stable use of the network by the communication device, when connected to the network of the first mode, if the communication quality of the first mode does not meet the preset conditions, then search for the network signal of the second mode and determine whether the communication quality of the second mode meets the preset conditions. When the communication quality of the second mode meets the preset conditions and the communication quality of the first mode does not meet the preset conditions, then connect to the network of the second mode. According to the process of updating the priority list, at this time, the priority of the first mode should be reduced to the priority of the second mode to update the current priority list from the first priority list to the second priority list. In one embodiment, the preset conditions include: the communication bandwidth is above the bandwidth threshold and / or the signal strength is above the strength threshold. The signal strength can be evaluated by selecting the parameter index of RSSI (Received Signal Strength Indicator). The bandwidth threshold can be selected as 20M when the first mode is the NR network and the second mode is the LTE network.

[0076] This application also provides a communication mode switching method. Please refer to Figure 8 The method includes step S802 and step S804.

[0077] S802, when both the wide area network connection and the wireless connection are enabled, determine the target communication mode from multiple communication modes.

[0078] It can be understood that a wide area network connection can also be referred to as a cellular connection. Generally, a communication device can connect to the cellular network provided by an operator through the operator's Subscriber Identity Module (SIM card), thereby accessing the Internet. A wireless connection, on the other hand, enables a communication device to access the Internet based on the wireless signal emitted by a wireless router. In this embodiment, the communication device is configured with multiple communication modes, and each communication mode has different preferences when choosing between a wide area network connection and a wireless connection to access the Internet. The target communication mode is one selected by the communication device from multiple communication modes in response to the user's selection.

[0079] S804, when the communication rate of the wireless connection method is greater than the threshold corresponding to the target communication mode, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method. The wide area network connection method is implemented based on the network search method in any of the above embodiments.

[0080] Specifically, the threshold corresponding to each communication mode is different. This threshold reflects the lower limit of the wireless network communication rate when the user selects the wireless connection method. Only when the communication rate of the wireless connection method reaches this threshold will the wireless connection method be preferentially selected to save the user's traffic; otherwise, the wide area network connection method will be selected to ensure communication performance. Therefore, the higher the communication mode's requirement for communication rate, the higher the corresponding threshold.

[0081] In a specific embodiment, the multiple communication modes include a performance mode, a balanced mode, and a traffic-saving mode. When the communication rate of the wireless connection method is greater than the threshold corresponding to the target communication mode, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method, including:

[0082] 1) When the target communication mode is the performance mode, if the communication rate of the wireless connection method is greater than the first threshold, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method.

[0083] 2) When the target communication mode is the balanced mode, if the communication rate of the wireless connection method is greater than the second threshold, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method. The second threshold is less than the first threshold.

[0084] 3) When the target communication mode is the traffic-saving mode, if the communication rate of the wireless connection method is greater than the third threshold, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method. The third threshold is less than the second threshold.

[0085] It can be understood that from the data-saving mode to the performance mode, the requirement for communication rate gradually increases, and the traffic consumption of users also gradually increases, thus resulting in the quantitative relationship that the first threshold is greater than the second threshold, and the second threshold is greater than the third threshold. The communication rate of the wireless connection method can be determined according to the communication protocols supported by the wireless router. For example, wireless communication protocols such as 11ax and 11ac can be comparable to the communication rate of the 5G network, and wireless communication protocols such as 11n and 11g can be comparable to the communication rate of the 4G network. In a specific embodiment, the first threshold matches the average communication rate of the 5G network, the second threshold matches the average communication rate of the 4G network, and the third threshold matches the average communication rate of the 3G network.

[0086] The embodiment of the present application further provides a network search device, which includes a network search module, a first update module, and a second update module. The network search module is used to search for networks according to an updatable priority list. The first update module and the second update module can update the priority list. Specifically, when the first update module is used to search for networks according to the first priority list, if it connects to a network of the first network mode, it maintains the first priority list; if it connects to a network of the second network mode, it reduces the priority of the first network mode to the priority of the second network mode, so as to update the current priority list to the second priority list. The first priority list includes multiple network modes, and the search priorities include the first network mode, the second network mode, and the third network mode in descending order. When the second update module is used to search for networks according to the second priority list, if it connects to a network of the first network mode, it restores the current priority list to the first priority list; if it connects to a network of the second network mode, it reduces the priority of the first network mode to the priority of the third network mode, so as to update the current priority list to the third priority list; if it connects to a network of the third network mode, it closes the search for the first network mode and reduces the priority of the second network mode to the priority of the third network mode, so as to update the current priority list to the fourth priority list.

[0087] In one of the embodiments, the device further includes a third update module. When the third update module is used to search for networks according to the third priority list, if it connects to a network of the first network mode, it restores the current priority list to the first priority list; if it connects to a network of the second network mode, it maintains the third priority list; if it connects to a network of the third network mode, it closes the search for the first network mode and reduces the priority of the second network mode to the priority of the third network mode, so as to update the current priority list to the fourth priority list.

[0088] In one embodiment, the first priority list further includes a fourth network mode, and the network search priority of the fourth network mode is lower than that of the third network mode. The apparatus further includes a fourth update module. When the fourth update module performs network search according to the fourth priority list, if it is connected to a network of the second network mode, it restores the current priority list to the second priority list; if it is connected to a network of the third network mode, it closes the search for the network of the second network mode to update the current priority list to the fifth priority list; if it is connected to a network of the fourth network mode, it reduces the priorities of the second and third network modes to the priority of the fourth network mode to update the current priority list to the sixth priority list.

[0089] In one embodiment, the first priority list further includes a network mode to be retired, and the network search priority of the network mode to be retired is lower than that of the fourth network mode. The apparatus further includes a fifth update module. When the fifth update module performs network search according to the sixth priority list, if it is connected to a network of the second network mode, it restores the current priority list to the second priority list; if it is connected to a network of the third network mode, it restores the current priority list to the fourth priority list; if it is connected to a network of the fourth network mode, it closes the search for the networks of the second and third network modes to update the current priority list to the seventh priority list; if it is connected to the network mode to be retired, it reduces the priorities of the second, third, and fourth network modes to the priority of the network mode to be retired to update the current priority list to the eighth priority list.

[0090] In one embodiment, the apparatus further includes a sixth update module. When the sixth update module performs network search according to the eighth priority list, if it is connected to a network of the second network mode, it restores the current priority list to the second priority list; if it is connected to a network of the third network mode, it restores the current priority list to the fourth priority list; if it is connected to a network of the fourth network mode, it restores the current priority list to the sixth priority list; if it is connected to a network of the network mode to be retired, it closes the search for the networks of the second, third, and fourth network modes to update the current priority list to the ninth priority list.

[0091] An embodiment of the present application further provides a communication mode switching apparatus. The communication mode switching apparatus includes a mode determination module and a connection mode selection module. The mode determination module is used to determine a target communication mode from multiple communication modes when both a wide area network connection and a wireless connection are enabled. The connection mode selection module is used to perform communication using the wireless connection mode when the communication rate of the wireless connection mode is greater than the threshold corresponding to the target communication mode; otherwise, it performs communication using the wide area network connection mode. The wide area network connection mode is implemented based on the network search apparatus in any of the above embodiments.

[0092] In one embodiment, the multiple communication modes include a performance mode, a balanced mode, and a data-saving mode. The connection method selection module is configured to, when the target communication mode is the performance mode, if the communication rate of the wireless connection method is greater than a first threshold, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method. When the target communication mode is the balanced mode, if the communication rate of the wireless connection method is greater than a second threshold, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method. The second threshold is less than the first threshold. When the target communication mode is the data-saving mode, if the communication rate of the wireless connection method is greater than a third threshold, communicate using the wireless connection method; otherwise, communicate using the wide area network connection method. The third threshold is less than the second threshold.
