Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a network stationing method and related equipment. Background Art

[0002] Currently, watches that support an embedded subscriber identity module (ESIM) will perform a cell search and cell registration after the Bluetooth connection between the watch and the mobile phone is disconnected. When the watch performs a cell search and cell registration, there are two situations: ① If there is a historical frequency point, the watch will first perform a cell search based on the historical frequency point to obtain the cell information of the cell on the historical frequency point; then, it will select a cell for registration. In this way, there is a situation where the signal of the cell where the watch finally registers is poor. ② If there is no historical frequency point, the watch will perform a full-band network search to read the cell information of the cell with the strongest signal on each frequency point; then, it will select a cell for registration. This causes the watch to stay on the network for a longer time.

[0003] Therefore, after the Bluetooth connection between the watch and the mobile phone is disconnected, how to quickly select a cell with better signal strength for registration becomes an urgent problem to be solved. Summary of the Invention

[0004] The embodiments of the present application provide a method for registering on a network and related devices, which enable a second device to quickly select a cell with better signal strength for registration when detecting that the short-range wireless communication connection between the second device and the first device has been disconnected.

[0005] In a first aspect, an embodiment of the present application provides a method for stationing on a network, applied to a second device, the method comprising:

[0006] detecting whether the short-range wireless communication connection with the first device is disconnected;

[0007] If it is detected that the short-range wireless communication connection with the first device is disconnected, a cell is selected for registration based on the cell information, where the cell information includes cell identifiers of the cells obtained by sorting the cells in descending order of signal strength.

[0008] After implementing the method provided in the first aspect, since the cell information includes the cell identifiers of each cell obtained by sorting the cells in order of signal strength from strong to weak, when the second device detects that the short-range wireless communication connection with the first device has been disconnected, it can quickly select a cell with better signal strength for registration based on the cell information. In this way, not only can the time for the second device to perform cell registration be saved, but also when the signal of the cell on the historical frequency point is weak and the signal of the cell on the non-historical frequency point is strong, the second device can register with the cell with better signal. In addition, the second device does not need to perform cell search, thereby reducing the power consumption caused by cell search.

[0009] In combination with the first aspect, in an optional implementation, before detecting whether the short-range wireless communication connection with the first device is disconnected, the method further includes: receiving cell information from the first device.

[0010] In this embodiment, the second device may also receive cell information from the first device before detecting whether the short-range wireless communication connection between the second device and the first device is disconnected. In this way, when the second device detects that the short-range wireless communication between the second device and the first device has been disconnected, there is no need to search for a cell, and the second device may directly select a cell with better signal strength for registration based on the received cell information.

[0011] In combination with the first aspect, in an optional implementation, selecting a cell for registration based on the cell information includes: selecting cells for registration in order of signal strength from strong to weak in the cell information until registration is successful.

[0012] In this implementation, the second device may select cells for registration in order of signal strength from strong to weak. This not only allows the second device to select cells with better signal strength for registration, but also improves the success rate of cell registration.

[0013] In combination with the first aspect, in an optional implementation, the method further includes: if all cells in the selected cell information have attempted to register and all registrations have failed, determining its own location information; obtaining the cell information corresponding to the location information; and selecting a cell for registration based on the cell information corresponding to the location information.

[0014] In this embodiment, after the second device fails to register with all cells in the selected cell information, it can select a cell for registration based on the cell information corresponding to its location information. This can improve the success rate of cell registration.

[0015] In a second aspect, an embodiment of the present application provides a method for stationing on a network, which is applied to a first device, and the method includes:

[0016] Determine cell information, the cell information including cell identifiers of each cell obtained by sorting the cells in descending order of signal strength;

[0017] The cell information is sent to the second device, where the second device is a device that has a short-range wireless communication connection with the first device. The cell information is used by the second device to select a cell for registration when it detects that the short-range wireless communication connection with the first device is disconnected.

[0018] After implementing the method provided in the second aspect, the first device sends determined cell information to the second device, where the cell information includes the cell identifiers of each cell sorted in order from strong to weak according to the signal strength of each cell. This helps the second device to quickly select a cell with better signal strength for registration based on the received cell information when it detects that the short-range wireless communication connection with the first device is disconnected.

[0019] In combination with the second aspect, in an optional implementation, determining the cell information includes: if it is detected that the second device is connected, periodically searching for each cell in the current network environment; and determining the cell information based on each searched cell.

[0020] In this implementation, the first device can periodically search for cells in the current network environment and sort the cells in descending order of signal strength to obtain cell identifiers for each cell, thereby obtaining cell information. The first device can then send the cell information to the second device, enabling the second device to quickly select a cell with better signal strength for registration.

[0021] In combination with the second aspect, in an optional implementation, before responding to a first operation input to the first device, a step of sending cell information to the second device is performed, where the first operation is used to indicate confirmation of disconnecting the short-range wireless communication connection with the second device.

[0022] In this embodiment, the first device may send cell information to the second device before receiving an indication from the user input confirming the operation of disconnecting the short-range wireless communication connection with the second device. This helps the second device to quickly select a cell with better signal strength for registration based on the cell information when it detects that the short-range wireless communication connection with the first device has been disconnected.

[0023] In combination with the second aspect, in an optional embodiment, the first operation is an operation acting on the first control, and the method also includes: in response to the second operation input to the first device, outputting the first control of whether to disconnect the short-range wireless communication connection with the second device; receiving the first operation input to the first device through the first control.

[0024] In combination with the second aspect, in an optional implementation, the method further includes: determining whether the signal strength of communication with the second device reaches a first threshold; if it is determined that the signal strength of communication with the second device reaches the first threshold, executing the step of sending cell information to the second device.

[0025] In this embodiment, the first device may send cell information to the second device when the communication strength with the second device is weak. This helps the second device to quickly select a cell with better signal strength for registration based on the cell information when it detects that the short-range wireless communication connection with the first device has been disconnected.

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the 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. Mentioning "embodiment" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present embodiment application. The appearance of this phrase in various positions in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of this application.

[0048] In the specification, claims, and accompanying drawings of this application, the terms "first," "second," and the like are used to distinguish different objects and are not used to describe a particular order. Furthermore, the terms "including," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a list of steps or elements may be included, or alternatively, steps or elements not listed may be included, or other steps or elements inherent to the process, method, product, or apparatus may be included.

[0049] Only part relevant to the present application is shown in the accompanying drawings, not all of it. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processing or methods depicted as flow charts. Although flow charts describe various operations (or steps) as sequential processing, many operations therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of various operations can be rearranged. When its operation is completed, the processing can be terminated, but can also have additional steps not included in the accompanying drawings. The processing can correspond to methods, functions, procedures, subroutines, subprograms, etc.

[0050] As used in this specification, the terms "component," "module," "system," "unit," and the like are used to refer to computer-related entities, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a unit can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, an execution thread, a program, and / or distributed between two or more computers. In addition, these units can be executed from various computer-readable media having various data structures stored thereon. Units can communicate, for example, through local and / or remote processes based on signals having one or more data packets (e.g., data from a second unit interacting with another unit in a local system, a distributed system, and / or a network. For example, the Internet interacts with other systems via signals).

[0051] Currently, after an ESIM-enabled watch loses its Bluetooth connection to a phone, it controls the modem to power on, thereby powering on the ESIM and performing a cell search and registration. However, during this process, the watch may encounter the following issues: ① The signal strength of the cell ultimately registered by the watch is poor; ② The watch remains on the network for a long time.

[0052] An embodiment of the present application provides a method for staying on a network, in which a second device detects whether a short-range wireless communication connection between the second device and the first device is disconnected; if the second device detects that the short-range wireless communication connection between the second device and the first device is disconnected, the second device selects a cell for registration based on cell information; wherein the cell message includes a cell identifier of each cell obtained by sorting the cells in order of signal strength from strong to weak.

[0053] The implementation of the network access method provided by this application has the following beneficial effects:

[0054] (1) When the second device detects that the short-range wireless communication connection with the first device has been disconnected, it can quickly select a cell with better signal strength for registration based on the cell information. This not only saves the second device time in cell registration, but also allows the second device to register with a cell with better signal strength when the signal of the cell on the historical frequency point is weak and the signal of the cell on the non-historical frequency point is strong.

[0055] (2) The second device does not need to perform cell search, thereby reducing power consumption caused by cell search.

[0056] In this application, the first device may be a device equipped with Or devices with other operating systems, such as mobile phones, tablet computers, desktop computers, laptop computers, handheld computers, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, as well as cellular phones, personal digital assistants (PDAs), augmented reality (AR) devices, virtual reality (VR) devices, artificial intelligence (AI) devices, wearable devices, in-vehicle devices, smart home devices and / or smart city devices, etc. This application does not impose any special restrictions on the specific type of the first device.

[0057] In this application, the second device can be a device that has a short-range wireless communication connection with the first device, such as a watch or smart bracelet that supports ESIM. This application does not impose any special restrictions on the specific type of the second device.

[0058] Optionally, when the first device is a mobile phone and the second device is a watch supporting ESIM, the subscriber identity module (SIM) card of the first device and the ESIM card of the second device belong to the same operator.

[0059] The following takes the short-range wireless communication connection between the first device and the second device as an example, wherein the short-range wireless communication connection between the first device and the second device is a Bluetooth connection. Figures 1a to 1c The application scenarios of the network stationing method provided in the embodiment of the present application are introduced.

[0060] Figure 1a Schematic diagram of a short-range wireless communication system provided by an embodiment of the present application. Figure 1a As shown, the first device 101 is a smart phone and the second device 102 is a smart watch. Both the first device 101 and the second device 102 have their Bluetooth functions turned on, and a communication connection is established between the first device 101 and the second device 102 via Bluetooth.

[0061] like Figure 1b As shown, the default user interface provided by the settings application after the first device 101 is opened is displayed. This user interface may include multiple functional options such as airplane mode, WiFi, Bluetooth, personal hotspot, and mobile network. The first device 101 can detect user touch operations on different functional options in the user interface 11 and, in response to the operations, can turn on or off functions such as airplane mode, WiFi, Bluetooth, personal hotspot, and mobile network.

[0062] Among them, the "Bluetooth" option 111 in the user interface is used to turn on or off the Bluetooth function of the first device 101, and the Bluetooth function can be used to establish a short-range wireless communication connection with the second device 102. The "Bluetooth" option 111 includes a setting switch 111A. The setting switch 111A can detect a user's touch operation and, in response to the operation, turn the Bluetooth function on or off on the first device 101. For example, when the main color displayed by the switch 111A is white, the Bluetooth function is in the off state, and when the main color displayed by the switch 111A is gray, the Bluetooth function is in the on state.

[0063] like Figure 1b As shown, the first device 101 can detect the user's touch operation on the setting switch 111A. In response to the operation, the first device 101 turns off the Bluetooth function, and the main body color of the setting switch 111A changes from gray to white.

[0064] like Figure 1c As shown, the user interface of the second device 102. The user interface may include a connection prompt information box 222. The connection prompt information box 222 is used to indicate whether the Bluetooth connection between the second device 102 and the first device 101 is successful or disconnected. For example, the connection prompt information box 222 may display "Bluetooth connection disconnected" and "Bluetooth connection successful". Exemplarily, if the second device 102 detects that the Bluetooth connection between it and the first device 101 is disconnected, the connection prompt information box 222 displays "Bluetooth connection disconnected". At this time, the second device 102 can select a cell for registration based on the cell information, wherein the cell information includes the cell identifiers of each cell obtained by sorting the signal strength of each cell from strong to weak.

[0065] The network access method provided in the embodiment of the present application is described in detail below.

[0066] See Figure 2 , Figure 2 This is a flow chart of a method for stationing on a network provided by an embodiment of the present application. Figure 2 As shown, the network stationing method may include but is not limited to the following steps:

[0067] S201: The second device detects whether the short-range wireless communication connection between the second device and the first device is disconnected.

[0068] Short-range wireless communication refers to a technology that can achieve a maximum distance of over 100 meters, utilizing semiconductor communication, wireless communication, and electronic network technologies to effectively connect and transmit information wirelessly within a 100-meter range. Simply put, it is a communication method that utilizes the ability of electromagnetic wave signals to propagate in free space to exchange information.

[0069] Optionally, the short-range wireless communication connection may include, but is not limited to, a wireless fidelity (WIFI) connection, a Bluetooth connection, a near field communication (NFC) connection, and the like.

[0070] S202. If the second device detects that the short-range wireless communication connection with the first device is disconnected, the second device selects a cell for registration based on the cell information, where the cell information includes cell identifiers of the cells sorted in descending order of signal strength.

[0071] Optionally, the cell information may be sent by the first device to the second device, or may be pre-stored by the second device, which is not limited here.

[0072] In an optional implementation, the second device selects a cell for registration based on the cell information. This can be done by sequentially selecting cells for registration based on the signal strength of each cell in the cell information, from strong to weak, until registration is successful. This allows the second device to select a cell with better signal strength for registration and improves the success rate of cell registration.

[0073] For example, assume that the cell information includes cell information for five cells, and the cell identifiers of the five cells are, for example, cell 1, cell 2, cell 3, cell 4, and cell 5. The five cells are sorted in descending order of cell signal strength, and the obtained cell identifiers are, in order, cell 3, cell 2, cell 5, cell 4, and cell 1. In this case, the second device may first select cell 3 for registration. If registration is successful, it is determined that it has successfully camped on cell 3, and can thus use the mobile network normally based on cell 3. If registration fails, the second device may sequentially select cell 2, cell 5, cell 4, and cell 1 for registration until registration is successful.

[0074] Optionally, if the second device detects that the short-range wireless communication connection with the first device is disconnected, it may control the modem to power on, thereby powering on the ESIM, and select a cell for registration based on the cell information.

[0075] In an embodiment of the present application, the second device detects whether the short-range wireless communication connection between the second device and the first device is disconnected; if the second device detects that the short-range wireless communication connection between the second device and the first device is disconnected, the second device selects a cell for registration based on the cell information, and the cell information includes the cell identifiers of each cell obtained by sorting the cells in order from strong to weak according to the signal strength of each cell. It can be seen that when the second device detects that the short-range wireless communication connection between the second device and the first device is disconnected, it can quickly select a cell with better signal strength for registration based on the cell information. In this way, not only can the time for the second device to perform cell registration be saved, but also when the signal of the cell on the historical frequency point is weak and the signal of the cell on the non-historical frequency point is strong, the second device can register with the cell with better signal.

[0076] See Figure 3 , Figure 3 This is a flow chart of another method for staying on the network provided by the embodiment of the present application. Figure 2 The difference between the stationing method shown is that Figure 3 In the method for stationing on the network shown, the second device also receives the cell information from the first device. Figure 3 In the method for stationing on the network shown in FIG, the cell information is described as an example in which the first device sends the cell information. Figure 3 As shown, the network stationing method may include but is not limited to the following steps:

[0077] S301. A first device determines cell information, where the cell information includes cell identifiers of cells obtained by sorting the cells in descending order of signal strength.

[0078] In an optional implementation, the first device may determine the cell information in the following manner: if it is detected that the second device is connected, periodically search for cells in the current network environment; and determine the cell information based on the searched cells.

[0079] In this embodiment, the first device determines the cell information based on each searched cell, which may include: sorting the cell identifiers of each cell in descending order of signal strength to obtain the sorted cell identifiers of each cell; and determining the cell information based on the sorted cell identifiers of each cell. Optionally, sorting the cell identifiers of each cell in descending order of signal strength may be sorting the cell identifiers of each cell in order of reference signal received power (RSRP) of the signals of each cell.

[0080] For example, suppose the first device detects that it is connected to the second device and searches for five cells in the current network environment for the first time, such as cell 1, cell 2, cell 3, cell 4, and cell 5. The first device sorts cells 1, 2, 3, 4, and 5 in descending order of signal strength, and the resulting cell identifiers are cell 3, cell 2, cell 5, cell 4, and cell 1, in that order. In this case, the first device can determine that the cell identifiers in the cell information are cell 3, cell 2, cell 5, cell 4, and cell 1, in that order.

[0081] In this implementation, the first device may further re-search each cell in the current network environment when detecting that the cell currently residing therein has changed.

[0082] Optionally, if the first device has preferentially registered a 5th-Generation Mobile Communication Technology (5G) cell, and the second device only supports 4G cells, if the first device detects that it has been connected to the second device, it can search for each 4G cell in the current network environment; and determine the 4G cell information based on the searched 4G cells.

[0083] S302: The first device sends cell information to the second device. Correspondingly, the second device receives the cell information from the first device.

[0084] In an optional implementation, the first device may perform a step of sending cell information to the second device before responding to a first operation input to the first device, where the first operation is used to indicate confirmation of disconnecting the short-range wireless communication connection with the second device.

[0085] In this embodiment, the first operation is an operation acting on the first control; the first device also outputs the first control of whether to disconnect the short-range wireless communication connection with the second device in response to the second operation input to the first device; and receives the first operation input to the first device through the first control.

[0086] The following takes the short-range wireless communication connection as an example, combined with Bluetooth connection Figure 4a and Figure 4b An example is given of the step of sending cell information to the second device by the first device before responding to the first operation input to the first device.

[0087] See Figure 4a , Figure 4a This is a user interface diagram provided by an embodiment of the present application. Figure 4a As shown in FIG, it is a schematic diagram of the default user interface provided by the setting application after the first device 401 opens the setting application. Figure 4aAs shown, the user interface may include multiple functional options such as airplane mode, WiFi, Bluetooth, personal hotspot, and mobile network. The first device 401 may detect a user's touch operation on different functional options in the user interface, and in response to the operation, the first device 401 may turn on or off functions such as airplane mode, WiFi, Bluetooth, personal hotspot, and mobile network.

[0088] like Figure 4a As shown, the user can click the second control 402 to input an operation of disconnecting the Bluetooth connection between the first device 401 and the second device.

[0089] See Figure 4b , Figure 4b This is another user interface diagram provided by the embodiment of the present application. Figure 4b As shown, the first control 403 is the first device 401 detecting that the user acts on Figure 4a In the case of a touch operation of the second control 402 in the first device, in response to the operation, the control is output. In this case, the first device 401 can send the cell information to the second device.

[0090] In another optional implementation, the first device may further determine whether the signal strength of communication with the second device reaches a first threshold; if it is determined that the signal strength of communication with the second device reaches the first threshold, the step of sending cell information to the second device is executed.

[0091] Optionally, the signal strength refers to a received signal strength indicator (RSSI). RSSI reflects the degree of signal attenuation, which is related to the received signal power and is generally a negative value. Optionally, when the first device determines the signal strength of communication with the second device based on the received signal power, the following formula (1) may be used.

[0092] RSSI=10logP (1)

[0093] In formula (1), RSSI represents the signal strength of the communication between the first device and the second device; P represents the signal power received by the first device.

[0094] Taking the short-range wireless communication connection between the first device and the second device as a Bluetooth connection as an example, assuming that the first threshold is -70 decibel relative to one milliwatt (dBm), if the first device determines that the signal strength RRSI of the Bluetooth communication between the first device and the second device reaches the first threshold (-70dBm), the cell information can be sent to the second device.

[0095] S303: The second device detects whether the short-range wireless communication connection between the second device and the first device is disconnected.

[0096] S304: If the second device detects that the short-range wireless communication connection with the first device is disconnected, the second device performs cell registration based on the cell information.

[0097] In an optional implementation, the specific description of steps S303 and S304 can refer to the description of the aforementioned steps S201 and S202 respectively, and will not be repeated here.

[0098] In an embodiment of the present application, the first device can determine the cell information when it is connected to the second device, and the cell information includes the cell identifiers of each cell obtained by sorting the cells in order of signal strength from strong to weak; the first device sends the cell information to the second device, and correspondingly, the second device receives the cell information from the first device; the second device registers the cell based on the cell information when it detects that the short-range wireless communication connection between it and the first device is disconnected. It can be seen that when the second device detects that the short-range wireless communication connection between it and the first device is disconnected, it can quickly select a cell with better signal strength for registration based on the cell information from the first device. In this way, not only can the time for the second device to perform cell registration be saved, but also when the signal of the cell on the historical frequency point is weak and the signal of the cell on the non-historical frequency point is strong, the second device can register with the cell with better signal. In addition, the second device does not need to perform cell search, thereby reducing the power consumption caused by cell search.

Figure 3 The difference between the stationing method shown is that Figure 5 The method for stationing on the network shown in FIG. 1 also describes how the second device performs cell registration if all cells selected in the cell information have been attempted to register and all registrations have failed. Figure 5 As shown, the network stationing method may include but is not limited to the following steps:

[0107] S506: If the second device has attempted to register in all cells selected in the cell information and all registrations have failed, the second device determines its own location information.

[0108] Optionally, the cell information corresponding to the location information may be cell information of all registrable cells in the area where the second device is located. Optionally, the number of cells in the cell information corresponding to the location information may be one or more.

[0109] S507: The second device obtains cell information corresponding to the location information.

[0110] In an optional implementation, the second device obtains the cell information corresponding to the location information in the following manner: based on the location information, obtains the cell information corresponding to the location information from the cloud.

[0111] S508. The second device selects a cell for registration based on the cell information corresponding to the location information.

[0112] In an optional embodiment, the second device selects a cell for registration based on the cell information corresponding to the location information, and can adopt the following method: determine the signal strength of each cell in the cell information corresponding to the location information; according to the order of the signal strength of each cell in the cell information corresponding to the location information from strong to weak, select the cell for registration in turn until the registration is successful.

[0113] Optionally, if the second device has attempted to register in all cells in the cell information corresponding to the selected location information and all registrations have failed, the second device may perform cell search and cell registration.

[0114] In an embodiment of the present application, the first device can search for each cell in the current network environment when it is connected to the second device, and determine the cell information based on each searched cell, the cell information including the cell identifier of each cell obtained by sorting the signal strength of each cell from strong to weak; when the short-range wireless communication connection between the first device and the second device is not disconnected, the first device sends the cell information to the second device, and correspondingly, the second device receives the cell information from the first device; when the second device detects that the short-range wireless communication connection between it and the first device is disconnected, it registers the cell based on the cell information; if the second device selects all cells in the cell information and attempts to register and all registrations fail, it can obtain the cell information corresponding to the location information, and select a cell for registration based on the cell information corresponding to the location information. It can be seen that if the second device selects all cells in the cell information and attempts to register and all registrations fail, it can select a cell for registration based on the cell information corresponding to the location information, thereby improving the success rate of cell registration.
