[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0049] The technical solutions provided by various embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0050] In related technologies, cells are often added to the FTA list due to temporary network anomalies, or other cells with the same TAC are normal, but access is not initiated due to restrictions on the protocol framework; this may lead to some extreme cases, especially when the UE is in a stationary state for a long time, the UE will have a long period of no service, seriously affecting the user experience.

[0051] Based on this, an embodiment of the present disclosure provides a network access method applied to a terminal device. Figure 1 A schematic diagram of a method for network access according to an exemplary embodiment Figure 1 ,like Figure 1 As shown, the network access method provided by the embodiment of the present disclosure includes at least the following steps:

[0052] Step 110: When the terminal device is in an out-of-service state, a first search is performed on a serving cell of the terminal device at the current moment to obtain a first search result;

[0053] Step 120: Detect whether there is a disabled cell identifier that meets the access standard in the disabled tracking area list at the current moment, and obtain a detection result;

[0054] Step 130: Determine a target cell based on the first search result and the detection result;

[0055] Step 140: Perform network access based on the target cell.

[0056] In the embodiments of the present disclosure, the terminal device may be a mobile communication terminal, a user equipment, a mobile device, or other equipment supporting various wireless communication technologies, etc. It should be noted that the specific type of the terminal device is not limited in the embodiments of the present disclosure.

[0057] Here, a cell is also called a cellular cell, which refers to an area covered by a base station or a part of a base station (sector antenna) in a cellular mobile communication system, in which a mobile device can reliably communicate with the base station through a wireless channel. The cellular mobile communication system includes at least one of the following: the fifth generation mobile communication network (5G) network standard, the fourth generation mobile communication network (4G) standard and the third generation mobile communication network (3G) standard, etc.

[0058] In step 110, the Out Of Service (OOS) state may refer to a state in which the terminal device cannot access the Internet, that is, is not connected to the network; for example, the OOS state of the terminal device may be reflected in that its web page cannot be opened for a long time.

[0059] The above-mentioned serving cell may be a cell that the above-mentioned terminal device can search in the current position at the current moment. In some embodiments, the above-mentioned serving cell may include a suitable cell and an acceptable cell; wherein a suitable cell refers to a cell in which the terminal device can reside and provide normal services; and an acceptable cell refers to a cell that is not enough to be a suitable cell, but at least meets the minimum conditions for basic services (e.g., emergency calls).

[0060] It can be understood that the terminal device is in a scenario where there are many base stations around it; that is, the terminal device is surrounded by multiple base stations from multiple different operators rather than multiple base stations from one operator. Accordingly, multiple base stations correspond to multiple different service cells, and the terminal device can perform a first search for multiple service cells around it at its current location.

[0061] In the embodiment of the present disclosure, the first search result may be that the terminal device searches for the service cell that meets the access criteria; or, the terminal device fails to search for the service cell that meets the access criteria, that is, the service cells around the current location of the terminal device do not meet the access criteria of the terminal device.

[0062] In step 120, the disabled tracking area list may be a set of disabled cell identifiers, i.e., a TAC set of disabled cells. The disabled cell identifier may be a TAC corresponding to the disabled cell; the TAC of the cell is allocated by the operator and mainly serves as a unique identifier for mobile user positioning; that is, one disabled cell identifier corresponds to one disabled cell.

[0063] Here, Tracking Area (TA) refers to a free movement area where the UE does not need to update the location service. TA is a cell-level configuration. Multiple cells can be configured with the same TA, and one cell can only belong to one TA.

[0064] The access standard may refer to the network parameters of the serving cell or the conditions that the network parameters of the forbidden cell corresponding to the forbidden cell identifier need to meet.

[0065] For example, the access standard may include an access signal threshold; for example, if the signal strength of a service cell exceeds a preset signal strength threshold specified in the network access protocol of the terminal device, it means that the service cell meets the access standard; or, if the signal power of the service cell exceeds a preset signal power threshold specified in the network access protocol of the terminal device, it can also mean that the service cell meets the access standard; etc. Alternatively, the access standard may also include a service type; for example, if the service type of a service cell is the same as the preset service type accepted by the terminal device, it means that the service cell meets the access standard, etc.

[0066] In the embodiment of the present disclosure, the above detection result may be that the above disabled cell identity that meets the access standard exists in the above disabled tracking area list, or the above disabled cell identity that meets the access standard does not exist in the above disabled tracking area list.

[0067] It can be understood that by detecting whether there is a disabled cell identifier that meets the access criteria in the disabled tracking area list at the current moment, when the serving cell cannot access the network, temporary network access is performed based on the disabled cell corresponding to the disabled cell identifier, thereby avoiding the terminal device being out of service for a long time.

[0068] In step 130, the target cell may be a cell to which the terminal device can access the network.

[0069] In the disclosed embodiment, the serving cell meeting the access standard or the forbidden cell meeting the access standard can be selected as the target cell to which the terminal device can access the network through the first search result and the detection result.

[0070] Here, determining the target cell based on the first search result and the detection result may include: based on the first search result being a service cell that meets the access criteria, taking the service cell as the target cell; or, based on the first search result being no service cell that meets the access criteria is found and the detection result being the presence of a disabled cell identifier that meets the access criteria, taking the disabled cell corresponding to the disabled cell identifier as the target cell; or, based on the first search result being no service cell that meets the access criteria is found and the detection result being the presence of a disabled cell identifier that meets the access criteria, taking the disabled cell as the target cell for network access, further performing a second search on the service cell of the terminal device at the current moment, and based on the second search result being no service cell that meets the access criteria is found, taking the service cell that meets the access criteria found in the second search as the target cell.

[0071] In step 140, performing network access based on the target cell may include: performing network access based on the target cell successfully; or performing network access based on the target cell failing.

[0072] Specifically, in one embodiment of the present disclosure, the network access method may further include:

[0073] Performing network connection and registration based on the target cell;

[0074] In a case where the network connection and registration of the target cell are both successful, determining that the target cell has successfully accessed the network;

[0075] In case of a network connection failure of the target cell and / or a registration failure of the target cell, it is determined that the target cell fails to perform network access.

[0076] In this way, the success or failure of the target cell's network access can be determined based on the success or failure of the target cell's network connection and registration, thereby improving the reliability of the terminal device's network access to the target cell.

[0077] In the disclosed embodiment, the successful network connection of the target cell can be understood as the establishment of a network connection between the terminal device and the target cell; at this time, the target cell cannot yet provide services for the terminal device. The successful network connection and registration of the target cell can be understood as the target cell being able to provide services for the terminal device. Therefore, it is necessary to meet the conditions that the network connection and registration of the target cell are both successful before the target cell is determined to have a successful network access; and if the network connection of the target cell fails, or the registration of the target cell fails, or the network connection and registration of the target cell both fail, it is determined that the target cell has failed to access the network.

[0078] The network access method provided by the embodiment of the present disclosure is, when the terminal device is in a no-service state, to perform a first search for the service cell of the terminal device at the current moment to obtain a first search result; to detect whether there is a disabled cell identifier that meets the access standard in the disabled tracking area list at the current moment to obtain a detection result; to determine the target cell based on the first search result and the detection result; and to perform network access based on the target cell. That is to say, unlike the related art in which the disabled cell corresponding to the disabled cell identifier in the disabled tracking area list is not considered during the network search process of the terminal device, the embodiment of the present disclosure searches the service cell of the terminal device and the disabled cell corresponding to the disabled cell identifier in the disabled tracking area list when the terminal device is in a no-service state, and not only considers the service cell that meets the access standard as the target cell, but also considers the disabled cell that meets the access standard as the target cell to perform network access, thereby increasing the possibility of the terminal device accessing the network when it is in a no-service state, avoiding the problem of the terminal device being out of service for a long time when the service cells of the terminal device cannot access the network, and improving the user experience.

[0079] In one embodiment of the present disclosure, the network access method may further include: in a case where the service cell satisfying the access criterion is searched out in the first search, taking the service cell satisfying the access criterion searched out in the first search as the target cell.

[0080] In this way, when the first search result is a service cell that meets the access standard, the service cell can be directly used as the target cell for subsequent network access, thereby ensuring that the terminal device can end the out-of-service state.

[0081] In one embodiment of the present disclosure, step 130 may be implemented in various ways.

[0082] A specific implementation example is given below. It should be noted that the following is only an example and is not intended to be limiting.

[0083] Figure 2 A schematic diagram of a network access method provided in an embodiment of the present disclosure Figure 2 See also Figure 2 , step 130 in the network access method provided by the embodiment of the present disclosure may include the following steps:

[0084] Step 131: If the serving cell that meets the access criteria is not found in the first search and there is a forbidden cell identifier that meets the access criteria, the forbidden cell corresponding to the forbidden cell identifier that meets the access criteria is used as the target cell.

[0085] In step 131, the disabled cell may be a cell corresponding to a TAC in the disabled tracking area list, that is, a cell whose TAC is disabled.

[0086] In the embodiment of the present disclosure, when there are multiple disabled cells that meet the above access criteria, a target cell can be determined based on the priorities of the multiple disabled cells to enable network access with the terminal device.

[0087] Here, the priorities of multiple disabled cells can be determined based on the degree to which the multiple disabled cells meet the above-mentioned access criteria. For example, when the above-mentioned access criterion is access signal strength, the multiple disabled cells are sorted based on the signal strengths of the multiple disabled cells; wherein the signal strengths of the above-mentioned disabled cells are in direct proportion to the priorities of the above-mentioned disabled cells; that is, the greater the signal strength of the disabled cells, the higher the priority of the disabled cells. Alternatively, when the above-mentioned access criterion is access signal power, the multiple disabled cells are sorted based on the signal power of the multiple disabled cells; wherein the signal power of the above-mentioned disabled cells is in direct proportion to the priority of the above-mentioned disabled cells; that is, the greater the signal power of the disabled cells, the stronger the signal received by the terminal device, and the higher the priority of the disabled cells.

[0088] It can be understood that the network access based on the above-mentioned disabled cell satisfying the above-mentioned access criteria as the target cell is temporary, so as to avoid the terminal device being out of service for a long time.

[0089] In some embodiments, the network access method may further include: when the service cell that meets the access criteria is not found in the first search, and there is no disabled cell that meets the access criteria, obtaining the first search result at the next moment and the detection result at the next moment, and determining the target cell based on the first search result at the next moment and the detection result at the next moment. In this way, when the target cell cannot be determined based on the first search result and detection result at the current moment, the terminal device enters the network search at the next moment, repeats the first search and detection at the next moment, to determine the target cell for network access, thereby ensuring that the terminal device can end the out-of-service state.

[0090] The network access method provided by the embodiment of the present disclosure can use the disabled cell corresponding to the disabled cell identifier as the target cell for subsequent network access when the first search result shows that no service cell meeting the access standard is found and the detection result shows that there is a disabled cell identifier meeting the access standard, thereby avoiding the problem of the terminal device being out of service for a long time when the service cells of the terminal device cannot access the network, thereby improving the user experience.

[0091] Figure 3 A schematic diagram of a network access method provided in an embodiment of the present disclosure Figure 3 . See Figure 3 , step 130 in the network access method provided by the embodiment of the present disclosure may include the following steps:

[0092] Step 132: In the process of performing network access based on the forbidden cell that meets the access standard as the target cell, performing a second search for the serving cell of the terminal device at the current moment;

[0093] Step 133: When the serving cell satisfying the access standard is found in the second search, the serving cell satisfying the access standard found in the second search is used as the target cell.

[0094] In step 132, the second search for the service cell of the terminal device at the current moment is performed on the basis of maintaining the service status with the above-mentioned disabled cell; that is, when the terminal device successfully accesses the network based on the above-mentioned disabled cell as the target cell, the second search for the service cell of the terminal device at the current moment is performed.

[0095] Here, the success of the terminal device's network access based on the above-mentioned forbidden cell can be determined by successfully performing network connection and registration based on the forbidden cell.

[0096] In step 133, when there are multiple serving cells that meet the above access criteria in the above second search, the target cell can be determined based on the priorities of the multiple serving cells to establish network access with the terminal device.

[0097] In the disclosed embodiments, the priorities of multiple service cells can be determined based on the degree to which the multiple service cells meet the above-mentioned access criteria. For example, in the case where the above-mentioned access criteria is access signal strength, the multiple service cells are ranked based on the signal strengths of the multiple service cells; wherein the signal strengths of the above-mentioned service cells are in direct proportion to the priorities of the above-mentioned service cells; that is, the greater the signal strength of the service cells, the higher the priority of the service cells. Alternatively, in the case where the above-mentioned access criteria is access signal power, the multiple service cells are ranked based on the signal power of the multiple service cells; wherein the signal power of the above-mentioned service cells is in direct proportion to the priority of the above-mentioned service cells; that is, the greater the signal power of the service cells, the stronger the signal received by the terminal device, and the higher the priority of the service cells.

[0098] It can be understood that the network access based on the above-mentioned service cell that meets the above-mentioned access standard as the target cell is stable, and the terminal device can access the service cell for a long time.

[0099] The network access method provided by the embodiment of the present disclosure can further perform a second search for the service cell of the terminal device at the current moment on the basis that the first search result shows that no service cell meeting the access standard is found and the detection result shows that there is a disabled cell identifier meeting the access standard, and the disabled cell is used as the target cell for network access. Based on the second search result showing that a service cell meeting the access standard is found, the service cell in the second search is used as the target cell for subsequent network access, thereby avoiding the terminal device from being in a no-service state for a long time and ensuring that the terminal device can access the service cell through the network when the network environment changes, thereby improving the user experience.

[0100] In some embodiments, the network access method may further include:

[0101] In the event that network access based on the disabled cell that meets the access criteria as the target cell fails, or in the event that the serving cell that meets the access criteria is not found in the second search, the first search result at the next moment and the detection result at the next moment are obtained, and the target cell is determined based on the first search result at the next moment and the detection result at the next moment.

[0102] In this way, when the disabled cell fails to access the network as the target cell or no service cell that meets the access criteria is found in the second search, the terminal device enters the network search at the next moment and repeats the first search and detection at the next moment to determine the target cell for network access, thereby ensuring that the terminal device can avoid being out of service for a long time and improving the user experience.

[0103] Among them, the first search result at the next moment can be obtained based on the first re-search of the service cell of the terminal device at the next moment; the detection result at the next moment can be obtained based on re-detecting whether there is a disabled cell identifier that meets the access criteria in the disabled tracking area list at the next moment.

[0104] Here, the disabled tracking area list at the next moment can be obtained by updating the disabled tracking area list at the current moment. Exemplarily, when the network access is successfully performed based on the disabled cell that meets the access standard as the target cell at the current moment, the disabled cell identifier corresponding to the disabled cell in the disabled tracking area list at the current moment is deleted; and the disabled tracking area list at the current moment after deletion is used as the disabled tracking area list at the next moment.

[0105] It should be noted that the time interval between the above-mentioned current moment and the above-mentioned next moment can be set based on the specific result of the terminal device accessing the network, and the embodiment of the present disclosure is not limited thereto.

[0106] In some embodiments, the network access method may further include:

[0107] Get the list of disabled tracking areas at the last moment;

[0108] Updating the forbidden tracking area list at the previous moment to obtain the forbidden tracking area list at the current moment;

[0109] or;

[0110] The historical forbidden tracking area list is used as the forbidden tracking area list at the current moment.

[0111] In this way, the disabled tracking area list at the current moment can be obtained by updating the disabled tracking area list at the previous moment, or the historical disabled tracking area list can be directly used as the disabled tracking area list at the current moment, so as to detect whether there is a disabled cell identifier that meets the access standard in the disabled tracking area list at the current moment in the subsequent process, thereby ensuring the real-time nature of the obtained disabled tracking area list and increasing the possibility of the terminal device accessing the network when it is in a no-service state.

[0112] The above-mentioned historical forbidden tracking area list may be pre-stored by a server outside the terminal device, and the terminal device may directly obtain the above-mentioned historical forbidden tracking area list from the server.

[0113] It should be noted that the time interval between the above-mentioned previous moment and the above-mentioned current moment can be set based on the specific result of the terminal device accessing the network, and the embodiment of the present disclosure is not limited thereto.

[0114] In one embodiment of the present disclosure, the specific process of updating the forbidden tracking area list at the previous moment to obtain the forbidden tracking area list at the current moment may include:

[0115] In the case where the network access is successfully performed based on the disabled cell meeting the access criterion as the target cell at the last moment, deleting the disabled cell identifier meeting the access criterion in the disabled tracking area list at the last moment;

[0116] The deleted disabled tracking area list at the previous moment is used as the disabled tracking area list at the current moment.

[0117] In this way, when network access is successfully performed at the previous moment based on a disabled cell that meets the access criteria as the target cell, the disabled tracking area list at the previous moment can be obtained by deleting the disabled cell identifier that meets the access criteria in the disabled tracking area list at the previous moment. In the subsequent process, it can be detected whether there is a disabled cell identifier that meets the access criteria in the disabled tracking area list at the current moment, thereby ensuring the real-time nature of the obtained disabled tracking area list and increasing the possibility of the terminal device accessing the network when it is in a no-service state.

[0118] It can be understood that if the network access was successful at the last moment based on the disabled cell that met the access criteria as the target cell, that is, the terminal device was able to access the network to the disabled cell at the last moment, then the disabled cell identifier corresponding to the disabled cell can be removed from the disabled tracking area list at the last moment, so that when the terminal device searches the network at the current moment, the disabled cell at the last moment can be classified into the service cell that the terminal device can search for the first time.

[0119] In some embodiments, the terminal device may mark the disabled cell identifiers that meet the above access criteria in the disabled tracking area list at the current moment, record the disabled cells corresponding to the disabled cell identifiers that meet the above access criteria in the target database, and directly obtain the corresponding disabled cells from the target database as the target cells if the serving cells that meet the above access criteria are not found in the first search and there are disabled cell identifiers that meet the above access criteria. For example, the target database may be acq2_db.

[0120] Figure 4 A schematic diagram of a network access method provided in an embodiment of the present disclosure Figure 4 .like Figure 4 As shown, the network access method provided in the embodiment of the present disclosure is only an example and not a limitation, and is intended to facilitate those skilled in the art to better understand the technical solution of the present disclosure. Figure 4 The network access method provided by the embodiment of the present disclosure can be applied to a terminal device, and can specifically include the following steps:

[0121] Step 401: When the terminal device is in an out-of-service state, a first search is performed on a serving cell of the terminal device at the current moment to obtain a first search result;

[0122] Step 402: Obtain a list of forbidden tracking areas at the last moment;

[0123] Step 403: If the forbidden cell that meets the access criteria is used as the target cell for successful network access at the last moment, delete the forbidden cell identifier that meets the access criteria in the forbidden tracking area list at the last moment;

[0124] Step 404: Use the deleted disabled tracking area list at the previous moment as the disabled tracking area list at the current moment;

[0125] Step 405: Use the historical forbidden tracking area list as the forbidden tracking area list at the current moment;

[0134] See also Figure 4 and Figure 5 In one embodiment of the present disclosure, when the terminal device performs the first search, the terminal device such as UE can perform a full band scan, and the disabled cell corresponding to the disabled cell identifier that meets the access standard but is in the FTA list is marked and recorded in acq2_db. Then, if the UE still cannot register on the serving cell after the complete first search, the judgment on the disabled cell in acq2_db is added, and the disabled cell is temporarily attempted to access. When the disabled cell in acq2_db can connect to the UE network and register successfully, while maintaining the service state with the disabled cell, the serving cell around the UE at the current moment is searched for the second time. If a serving cell that meets the access standard is searched in the second search, the network connection and registration are directly performed based on the serving cell, and acq2_db is cleared; if the network access fails based on the disabled cell that meets the access standard as the target cell, or the serving cell that meets the access standard is not searched in the second search, the first search result at the next moment and the detection result at the next moment are obtained, and the target cell is determined based on the first search result at the next moment and the detection result at the next moment, and acq2_db is cleared.
