[0025] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The following describes the method, device, electronic device and storage medium for a terminal to return to the network according to an embodiment of the present application with reference to the accompanying drawings.

[0027] Figure 1 A flowchart of a method for a terminal to return to a network provided in an embodiment of the present application.

[0028] The executor of the method for returning the terminal to the network in the embodiment of the present application is a device for returning the terminal to the network, which can be set in an electronic device. The electronic device can be a terminal, such as a smart phone, a smart watch or other wearable devices, etc., which is not limited in this embodiment.

[0029] like Figure 1 As shown, the method may include the following steps:

[0030] Step 101, in response to the end of the drawing time of the neighboring area map of the terminal and the terminal entering a service abnormality state from the first cell of the target network, obtain the neighboring area map of the first cell.

[0031] Among them, the duration of neighborhood map drawing is a duration set based on demand, for example, 3 days. During the duration of neighborhood map drawing, the cell information of other cells to which the terminal switches or reselects from the currently registered cell will be recorded based on the cell currently registered by the terminal, so as to record the switching and reselection behavior of the terminal under different network states. Optionally, a countdown for the duration of neighborhood map drawing can be set, and the duration of neighborhood map drawing ends when the countdown ends.

[0032] Among them, the target network is a mobile communication network, such as an independent networking SA network in a 5G network, so the terminal is an independent networking SA terminal; such as a non-independent networking BSA network in a 5G network, so the terminal is a non-independent networking NSA terminal.

[0033] The first cell is a cell that the terminal is currently connected to and can provide normal services. The abnormal service status includes the no service status and the limited service status, wherein the no service status is the OOS status; the limited service status means that the services enjoyed by the terminal are restricted, for example, only emergency call services can be made, and other services cannot be enjoyed.

[0034] In an embodiment of the present application, when it is detected that the terminal enters a service abnormality state from the first cell of the target network, that is, enters a no-service state or a restricted-service state, a neighboring cell map of the first cell is obtained. The neighboring cell map of the first cell stores the cell information of the neighboring cell to which the terminal switches or reselects from the first cell within a set time period. The cell information includes the frequency and identification information of the cell. That is to say, the neighboring cell map records the terminal's switching and reselection behavior under different network states.

[0035] Step 102: During the sleep cycle of the terminal re-searching for cells, the cell information recorded in the neighboring cell map is searched according to the search strategy corresponding to the service abnormality state to obtain a registrable target cell.

[0036] In an embodiment of the present application, when it is detected that the terminal enters a service abnormality state from the first cell of the target network, the terminal enters a network search process, also known as a cell search process, that is, re-searching the cell. Thus, during the sleep cycle of the search cell, according to the cell information of the neighboring cells recorded in the neighboring cell map, the search strategy corresponding to the service abnormality state is executed to search the cell to obtain the target cell, thereby saving power consumption. Since the neighboring cell map records the cell information of each neighboring cell that has been historically registered, compared with the full-band cell search, the efficiency and reliability of searching for the registrable target cell are increased, thereby achieving rapid determination of the registrable target cell.

[0037] Different service abnormality states have different corresponding search strategies to meet the efficiency of quickly determining the registrable target cell in different scenarios.

[0038] Step 103: Re-camp on the target network based on the target cell.

[0039] In the embodiment of the present application, after the terminal determines the target cell that can be registered, the terminal will register with the target cell to achieve re-stationing in the target network corresponding to the target cell, and quickly return to the target network, thereby improving the efficiency of returning to the network.

[0040] In the method for returning the terminal to the network in the embodiment of the present application, in response to the end of the drawing time of the neighboring area map of the terminal and the terminal entering the service abnormality state from the first cell of the target network, the neighboring area map of the first cell is obtained, and during the sleep cycle of the terminal re-searching the cell, the cell information recorded in the neighboring area map is searched according to the search strategy corresponding to the service abnormality state to obtain a registrable target cell, and the target network is re-resident based on the target cell. During the sleep cycle of the terminal, the neighboring cells that have been accessed and recorded in the neighboring area map of the first cell are searched, which improves the efficiency of searching for the registrable target cell, thereby enabling the terminal to quickly restore the connection to the target network.

[0041] Based on the above embodiments, Figure 2 A flowchart of another method for a terminal to return to a network provided in an embodiment of the present application is shown as follows: Figure 2 As shown, the method comprises the following steps:

[0042] Step 201, in response to the end of the drawing time of the neighboring area map of the terminal and the terminal entering a service abnormality state from the first cell of the target network, obtain the neighboring area map of the first cell.

[0043] Among them, step 201 can refer to the explanation in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0044] Step 202: During the sleep period when the terminal searches for cells again, the search priorities of the multiple cell lists included in the neighboring cell map are obtained.

[0045] Among them, the neighboring cell map includes multiple cell lists, and different cell lists record the switching and reselection behaviors of the terminal under different network states, that is, record the cell information to which the terminal switches or reselects under different network states. The search strategy corresponding to the out-of-service state is to set the search priority of the multiple cell lists included in the neighboring cell map corresponding to the first cell, wherein the multiple cell lists include a first cell list and a second cell list, wherein the first cell list includes the normal service cell switched or reselected from the first cell; and the second cell list includes the restricted service cell switched or reselected from the first cell. The search strategy of the terminal in the out-of-service state is to search for the cell that can provide normal service first and register to the cell that can provide normal service, and the first cell list records the normal service cell that is switched or reselected to, so that the search priority of the first cell list is higher than the search priority of the second cell list, so as to search for the target cell that can be registered and provide normal service as soon as possible, so as to restore the target network connection as soon as possible.

[0046] In one implementation of the embodiment of the present application, the sleep cycle of the terminal re-searching the cell means waking up the terminal at a set time interval during the sleep cycle and controlling the terminal to search for the cell. For example, if the sleep cycle is one hour and the set time interval is 10 minutes, the terminal will be awakened once every 10 minutes, and the cell search will be performed according to the search strategy corresponding to the abnormal service state of the terminal, so as to quickly restore the network connection.

[0047] Step 203: Search the first cell list for cells in which the terminal can be registered according to the search strategy corresponding to the out-of-service state.

[0048] In one implementation of the embodiment of the present application, there is only one first cell list, and a search is first performed in the first cell list for cells in which the terminal can be registered. By preferentially searching for each cell in the first cell list that has records of normal services that have been switched or reselected, the efficiency of the terminal registering with each cell can be improved, so that the terminal can quickly restore network connection.

[0049] In another implementation of the embodiment of the present application, there are multiple first cell lists, which are respectively referred to as the first normal neighboring cell list, the second normal neighboring cell list and the third normal neighboring cell list. The first normal neighboring cell list includes the second cell with normal service switched or reselected from the first cell; the second normal neighboring cell list includes the third cell with normal service switched or reselected from the first cell after being disconnected from the network; the third normal neighboring cell list includes the fourth cell with restricted service switched or reselected from the first cell, and the fifth cell with normal service switched or reselected from the fourth cell. Among them, the search priorities corresponding to the first normal neighboring cell list, the second normal neighboring cell list and the third normal neighboring cell list are from high to low, that is, the search priority of the first normal neighboring cell list is greater than that of the second normal neighboring cell list, and the search priority of the second normal neighboring cell list is greater than that of the third normal neighboring cell list. Thus, the first normal neighboring cell list is first searched for cells that the terminal can register. If the cells are found, the search is terminated and the searched cells are used as the target cells. If the cells are not found, the second normal neighboring cell list is searched. If the cells are found, the search is terminated and the searched cells are used as the target cells. If the cells are not found, the third normal neighboring cell list is searched. If the cells are found, the search is terminated and the searched cells are used as the target cells. If the cells are not found, the subsequent step 204 is executed.

[0050] Step 204: In response to not finding a cell in which the terminal can be registered in the first cell list, searching the second cell list for a cell in which the terminal can be registered.

[0051] Step 205: In response to searching for a cell in the second cell list where the terminal can register, the cell in which the terminal can register is used as a target cell.

[0052] In an embodiment of the present application, in response to not finding a cell in which the terminal can register in the first cell list, a search is performed on the second cell list for cells in which the terminal can register, so as to quickly search for a restricted service cell in which the terminal can register, and reside in the target network based on the restricted service cell, so as to get out of the out of service state as soon as possible.

[0053] Step 206: In response to searching for a cell in the first cell list where the terminal can register, the cell in which the terminal can register is used as a target cell.

[0054] In the embodiment of the present application, if a cell that the terminal can register is searched in the first cell list, the registrable cell is used as the target cell, so that the terminal can quickly re-resident on the target network based on the target cell.

[0055] Step 207: Re-camp on the target network based on the target cell.

[0056] For details, please refer to the explanations in the aforementioned embodiments, and the principles are the same and will not be repeated here.

[0057] In the method for returning the terminal to the network in the embodiment of the present application, a neighboring cell map is used to record the terminal's switching and reselection behaviors in different network states. When it is detected that the terminal registers no service cell, that is, it is in a no service state, the network search plan is intelligently adjusted, that is, according to the search plan corresponding to the no service state, the various frequency point cells recorded in the neighboring cell map are searched first during the terminal's sleep cycle, so that the terminal can quickly restore the network connection. At the same time, searching the network during the sleep cycle can save the terminal power consumption.

[0058] Based on the above embodiments, the present application provides another method for a terminal to return to the network. Figure 3 A flowchart of another method for a terminal to return to a network provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the method comprises the following steps:

[0059] Step 301, in response to the end of the drawing time of the neighboring area map of the terminal and the terminal entering a service abnormality state from the first cell of the target network, the neighboring area map of the first cell is obtained.

[0060] Among them, step 301 can refer to the explanation in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0061] Step 302 searches the third normal neighboring cell list in the first cell list according to a search strategy corresponding to the restricted service state during the sleep cycle of the terminal re-searching the cell.

[0062] In an embodiment of the present application, the terminal is in a restricted service state. The terminal can re-switch or reselect to a cell in a normal service state in the restricted service state. In order to improve the efficiency and reliability of selecting cells with normal service and increase the efficiency and reliability of reconnecting to the network, the third normal neighboring area list in the first cell list can be searched during the sleep cycle of the terminal re-searching the cell. The third normal neighboring area list records the switching or reselection from the first cell to the fourth cell with restricted service, and the switching or reselection from the fourth cell to the fifth cell with normal service. In other words, the third normal neighboring area list records the fifth cell with normal service to which the terminal switched when the network was in a restricted service state. Therefore, by searching the third normal neighboring area list, the terminal can quickly determine the cell with normal service that can be registered, thereby improving the efficiency and reliability of the terminal in restoring network connection.

[0063] Step 303: In response to obtaining a registrable cell through searching in the third normal neighbor cell list, the registrable cell is used as a target cell.

[0064] Step 304: Re-camp on the target network based on the target cell.

[0065] For details, please refer to the explanations in the aforementioned embodiments, and the principles are the same and will not be repeated here.

[0066] In the method for the terminal to return to the network in the embodiment of the present application, a neighboring cell map that records the terminal's switching and reselection behaviors under different network states is used. When it is detected that the terminal is registered in a restricted service cell, that is, in a restricted service state, the network search plan is intelligently adjusted, that is, according to the search plan corresponding to the restricted service state, the various frequency cells recorded in the neighboring cell map are searched first during the terminal's sleep cycle, so that the terminal can quickly restore the network connection. At the same time, searching the network during the sleep cycle can save the power consumption of the terminal.

[0067] Based on the above embodiment, in the embodiment of the present application, before obtaining the neighboring area map of the first cell, during the time when the terminal is in the neighboring area map drawing of the first cell, by recording the switching and reselection behavior of the terminal in different network states, the following is combined with Figure 4 , neighborhood map drawing is explained for different scenarios.

[0068] As an example, the terminal in the embodiment of the present application is an SA terminal, and the target network is a 5G SA network.

[0069] like Figure 4As shown, it is detected that the SA terminal is turned on and registered to the first cell, that is, the 5G cell CellA, that is, it is stationed in the 5G cell, and the service cell frequency and cell identification information currently registered by the terminal UE are recorded as CellA{freq,pci}. The learning cycle T_learn for neighbor map drawing is set to 3 days, and the countdown of T_learn is started, that is, the neighbor map drawing corresponding to the cell CellA is started.

[0070] In one scenario, while the terminal is in the first cell and the neighborhood map is being drawn, in response to detecting that the terminal switches or reselects from the first cell to a second cell that is in normal service, the cell information of the first cell and the cell information of the second cell are added to a first normal neighborhood list of the first cell, and a neighborhood map is generated based on the first normal neighborhood list. By drawing the neighborhood map, the terminal's switching or reselection behavior under normal network conditions is recorded.

[0071] As an example, if it is detected that the terminal switches or reselects another cell (including hetero-frequency hetero-system) CellB{freq,pci}, then cell B is recorded in the neighboring cell list of A, that is, the first normal neighboring cell list can be represented as N_normalGroup{CellA,{CellB,...,CellX}}. Among them, the other cell can be a hetero-frequency hetero-system cell, such as a cell of the long-term evolution LTE system.

[0072] In the second scenario, while the terminal is in the first cell and the neighborhood map is drawn, in response to detecting that the terminal is disconnected from the first cell and switching or reselecting the terminal from the first cell to a third cell in normal service, the cell information of the first cell and the cell information of the third cell are added to the second normal neighborhood list of the first cell, and a neighborhood map is generated based on the second normal neighborhood list, thereby recording the third cell in normal service to which the terminal is switched or reselected after being disconnected from the network in the second normal neighborhood list of the neighborhood map, thereby recording the behavior of the terminal switching or reselecting to the normal service network in the offline state.

[0073] As an example, if it is detected that the terminal is disconnected from the normal service state, that is, disconnected from the service cell CellA, and then registered in the cell CellB1 that can provide normal service (including cells of different frequencies and systems), the service cell CellA before the disconnection and the new cell CellB1 that is registered for normal service after the disconnection are recorded in A's second normal neighbor cell list. The second normal neighbor cell list can be represented by N_oosGroup{CellA,{CellB1,...,CellX1}}.

[0074] In the third scenario, while the terminal is in the neighborhood map drawing period of the first cell, in response to detecting that the terminal is disconnected from the first cell and the terminal is switched or reselected from the first cell to a fourth cell of restricted service, the cell information of the first cell and the cell information of the fourth cell are added to the second cell list of the first cell, and a neighborhood map is generated based on the second cell list, so that the fourth cell of restricted service to which the terminal is switched or reselected after being disconnected from the network is recorded in the second cell list of the neighborhood map, thereby recording the behavior of the terminal switching or reselecting to the restricted service network in the disconnected state.

[0075] As an example, if it is detected that the terminal is disconnected from the normal service state, that is, disconnected from the service cell CellA, and then registers for the limited service cell CellB2 to obtain the restricted service, the original service cell CellA and the subsequently registered restricted cell CellB2 are recorded in A's neighboring cell list, that is, the second cell list. The second cell list example is expressed as N_groupLimited{CellA,{CellB2,...,CellX2}}.

[0076] In the fourth scenario, while the terminal is in the first cell, within the duration of the neighborhood map drawing, in response to detecting that the terminal switches or reselects from the first cell to the fourth cell of restricted service, and then switches or reselects from the fourth cell to the fifth cell of normal service, the cell information of the first cell and the cell information of the fifth cell are added to the third normal neighborhood list of the first cell, and a neighborhood map is generated based on the third normal neighborhood list, thereby achieving the switching or reselection of the terminal from the normal service network to the cell of restricted service, and then switching or reselecting from the cell of restricted service to the fifth cell of normal service, thereby recording the fifth cell in the third normal neighborhood list of the neighborhood map, recording the terminal's behavior from the normal service network to the restricted service network and then to the normal service network.

[0077] As an example, if it is detected that the terminal registers a limited service cell from a normal service cell CellA, and then switches from the limited service network to a normal service cell CellB3, the original service cell CellA and the new service cell CellB3 in the limited service state are recorded in A's neighboring cell list, that is, the third normal neighboring cell list. An example of the third normal neighboring cell list is expressed as N_limitedGroup{CellA,{CellB3,...,CellX3}}.

[0078] As an implementation method, during the time when the terminal is in the first cell and the neighborhood map is drawn, the terminal may be in different network states, which will include the behavior of switching and reselecting the terminal in the above-mentioned different network states, that is, the neighborhood map may include multiple neighborhood lists under the above-mentioned four scenarios.

[0079] Furthermore, if it is detected that T_learn has timed out, the search network optimization corresponding to the terminal being in the out of service state oos or the limited service state limited service is enabled.

[0080] In one scenario, if the terminal switches from the serving cell to the out-of-service state, the cell search is performed in accordance with the search strategy corresponding to the abnormal service state during the sleep cycle of the terminal's network search process, that is, the terminal is determined to be in an off-network state and in the sleep cycle, and the search is performed in the order of N_normalGroup, N_oosGroup, N_limitedGroup, and N_groupLimited, that is, the neighboring cells saved in the N_normalGroup list are searched first, and if the network is not restored, the neighboring cells in the N_oosGroup are searched continuously, and if the network that can be registered is still not found, the neighboring cells in the N_limitedGroup list are searched next, and the neighboring cell search recorded in N_groupLimited has the lowest priority, so as to improve the efficiency and reliability of the terminal re-residence in the normal service network. At the same time, the searched cells are saved in the corresponding cell list of the neighboring cell map for timely update.

[0081] In another scenario, the terminal is currently in the limited service state. During the sleep cycle of the terminal's network search process, the second cell list is searched, that is, each neighboring cell (CellB3, ..., CellX3) saved in N_limitedGroup{CellA,{CellB3, ..., CellX3}} is searched. If the 5G target cell is found, the terminal registers to the found 5G target cell, so that the terminal can quickly restore the 5G network connection. At the same time, the searched cell is saved in the corresponding cell list of the neighboring cell map for timely update.

[0082] Furthermore, if the terminal eventually resumes service, the new neighboring area is added to the corresponding neighboring area map based on the aforementioned neighboring area map drawing algorithm, that is, the neighboring area map is updated. If the terminal is turned off or the SIM card is removed, the optimization is stopped and the neighboring area map data is cleared.

[0083] In order to implement the above embodiment, the embodiment of the present application also proposes a device for a terminal to return to the network.

[0084] Figure 5 A schematic diagram of the structure of an apparatus for returning a terminal to a network provided in an embodiment of the present application.

[0085] like Figure 5 As shown, the device may include:

[0086] The acquisition module 51 is used to acquire the neighbor map of the first cell in response to the terminal's neighborhood map drawing time ending and the terminal entering a service abnormality state from the first cell of the target network.

[0087] The search module 52 is used to perform a cell search on the cell information recorded in the neighboring cell map according to the search strategy corresponding to the service abnormality state during the sleep cycle of the terminal re-searching the cell, so as to obtain a registrable target cell.

[0088] The stationing module 53 is used to station again on the target network based on the target cell.

[0089] Further, in an implementation of the embodiment of the present application, the abnormal service state includes a no service state, and the search module 52 is specifically used to:

[0090] Acquire the search priorities of multiple cell lists included in the neighboring cell map; wherein the search priority of a first cell list included in the multiple cell lists is higher than that of a second cell list; the first cell list includes normal service cells switched or reselected from the first cell; and the second cell list includes restricted service cells switched or reselected from the first cell;

[0091] Searching the first cell list for cells in which the terminal can be registered according to the search strategy corresponding to the out-of-service state;

[0092] In response to not finding a cell in which the terminal can register in the first cell list, searching the second cell list for a cell in which the terminal can register;

[0093] In response to searching for a cell in which the terminal can be registered in the second cell list, the registrable cell is used as the target cell.

[0094] In one implementation of the embodiment of the present application, the search module 52 is specifically configured to:

[0095] In response to searching for a cell in the first cell list in which the terminal can be registered, the registrable cell is used as the target cell.

[0096] In one implementation of the embodiment of the present application, the first cell list includes a first normal neighbor cell list, a second normal neighbor cell list, and a third normal neighbor cell list ordered in descending order of search priority, wherein the first normal neighbor cell list includes a second cell with normal service that is switched or reselected from the first cell; the second normal neighbor cell list includes a third cell with normal service that is switched or reselected from the first cell after being disconnected from the network; and the third normal neighbor cell list includes a fourth cell with restricted service that is switched or reselected from the first cell, and a fifth cell with normal service that is switched or reselected from the fourth cell.

[0097] In an implementation of the embodiment of the present application, the service abnormality state includes a restricted service state, and the search module 52 is specifically used to:

[0098] Searching a third normal neighboring cell list in the first cell list according to a search strategy corresponding to the restricted service state;

[0099] In response to obtaining a registrable cell through searching in the third normal neighbor cell list, the registrable cell is used as the target cell.

[0100] In one implementation of the embodiment of the present application, the device further includes: a generating module.

[0101] A generation module is used to add the cell information of the first cell and the cell information of the second cell to a first normal neighboring cell list of the first cell in response to detecting that the terminal switches or reselects from the first cell to a second cell in normal service during the duration of the neighboring cell map drawing of the terminal in the first cell; and generate the neighboring cell map according to the first normal neighboring cell list.
