[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0023] The network connection method, electronic device, readable storage medium, and chip provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0024] See Figure 1 , is a flow chart of a network connection method provided by an embodiment of the present disclosure, the network connection method is applied to an electronic device, and the method includes the following steps:

[0025] Step S101: When the electronic device establishes a network connection with a first standalone network SA cell, obtain release status information of a first protocol data unit (PDU) session, where the first PDU session is a PDU session between the electronic device and the first SA cell;

[0026] Step S102: When it is determined based on the release status information that the first SA cell is in an abnormal state, a network connection with a target cell is established, where the target cell is a cell other than the first SA cell.

[0027] The electronic device may be various types of user equipment (UE) carried by a user. For ease of understanding, the electronic device is hereinafter referred to as UE.

[0028] The above-mentioned first SA cell can be a fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) SA cell.

[0029] The above-mentioned electronic device establishing a network connection with the first independent network SA cell may refer to: the UE establishing a network connection with the base station corresponding to the first SA cell. The specific network connection process may be:

[0030] The UE sends a PDU SESSION ESTABLISH REQTEST request to the base station of the first SA cell, wherein the PDU SESSION ESTABLISH REQTEST request is used to request the creation of the first PDU session; the base station of the first SA cell responds to the PDU SESSION ESTABLISH REQTEST request and sends a PDU SESSION ESTABLISHACCEPT message to the UE, wherein the PDU SESSION ESTABLISH ACCEPT message is a PDU session request acceptance message. After these two steps, the UE's network connection process is completed, and the process of creating the first PDU session is completed. At this time, the UE can access the Internet normally.

[0031] When a large number of different UEs establish network connections with the base station of the first SA cell at the same time, since the first SA cell may not be able to meet the Internet access needs of a large number of UEs at the same time, the first SA cell will actively disconnect the network connections of some UEs, that is, disconnect the PDU sessions of some UEs. After the first SA cell disconnects the PDU session between it and the UE, it will send a PDU release command to the UE: PDU SESSION RELEASE COMMAND.

[0032] Based on this, in one embodiment of the present disclosure, the release status information may include the PDU release command. It is also possible to predefine the situations in which a received PDU release command indicates a normal SA cell state, and to predefine the situations in which a received PDU release command indicates an abnormal SA cell state. Then, based on the release status information, it is possible to determine whether the first SA cell is in an abnormal state.

[0033] It is understandable that the above-mentioned first SA cell is in an abnormal state: it may mean that the first SA cell itself has a fault, or it may mean that the first SA cell is in an overload state due to an excessive number of UEs connected to the first SA cell.

[0034] The target cell may be any other cell other than the first SA cell that can provide network services for the electronic device, wherein the electronic device is located within the network coverage of the target cell.

[0035] In this implementation, when an electronic device establishes a network connection with a first SA cell, it is determined whether the first SA cell is in an abnormal state based on the release status information of the first PDU session, and when the first SA cell is in an abnormal state, a network connection between the electronic device and the target cell is established. In this way, since it is possible to timely identify whether the first SA cell is in an abnormal state based on the release status information of the first PDU session, and when it is identified that the first SA cell is in an abnormal state, the network connection of the electronic device is switched to other cells, it is beneficial for the electronic device to maintain a normal network connection.

[0036] Optionally, the release status information includes a first time difference, where the first time difference includes a time difference between a time point when the first PDU session is created and a time point when the first PDU session is released; before establishing a network connection between the electronic device and the target cell, the method further includes:

[0037] When the first time difference is less than a first preset value, it is determined that the first SA cell is in an abnormal state.

[0038] Specifically, a first timer can be pre-configured in the electronic device, wherein when the electronic device receives the PDU SESSION ESTABLISH ACCEPT message, that is, when the electronic device successfully establishes a network connection with the first SA cell, the first timer is controlled to start timing. When the PDU SESSION RELEASE COMMAND is received, that is, when the electronic device disconnects the network connection with the first SA cell, the first timer is controlled to end timing. The first time difference can be obtained by reading the timing duration of the first timer.

[0039] It is understandable that the first time difference may be a relatively short time difference, for example, the value range of the first time difference may be 0 to 10 seconds. That is, after the electronic device establishes a network connection with the first SA cell, the established network connection is immediately released by the first SA cell. In this case, it can be considered that the first SA cell is abnormal.

[0040] See Figure 2 , is a flow chart of a network connection method provided by an embodiment of the present disclosure, the method comprising the following steps:

[0041] After the electronic device is stationed in the first SA cell, it establishes a data PDU and sends a PDU session establishment request (PDU SESSION ESTABLISH REQTEST request) to the base station of the first SA cell;

[0042] The base station of the first SA cell sends a PDU session request acceptance message (PDU SESSION ESTABLISH ACCEPT message) to the electronic device in response to the PDU session establishment request. After receiving the PDU session establishment request acceptance message, the electronic device starts a first timer.

[0043] If the PDU session release command (PDU SESSION RELEASE COMMAND) is not received before the first timer expires, the electronic device normally resides in the first SA cell, wherein the timing duration set by the first timer is the size of the first time difference;

[0044] If the PDU session release command is received before the first timer expires, it is determined that the first SA cell is in an abnormal state, and a network connection is established between the electronic device and the target cell.

[0045] It is understandable that after the first timer times out, if the network connection between the electronic device and the first SA cell is released, it is deemed to be released normally, that is, the first SA cell is deemed to be in a normal state. In this case, the electronic device establishes a network connection with the first SA cell again, and after successfully establishing a network connection with the first SA cell, the first timer is started to re-time, and the above judgment process is repeated, that is, before the first timer times out, the network connection between the electronic device and the first SA cell is released, then it is determined that the first SA cell is in an abnormal state.

[0046] In addition, in another embodiment of the present disclosure, after receiving the PDU session release command, it is also possible to determine whether the first timer has timed out to determine whether the first SA cell is in an abnormal state. Specifically, after receiving the PDU session release command, if the first timer has timed out, it is determined that the first SA cell is in a normal state. Correspondingly, after receiving the PDU session release command, if the first timer has not timed out, it is determined that the first SA cell is in an abnormal state.

[0047] In this embodiment, by determining the time difference between the time point when the first PDU session is created and the time point when the first PDU session is released, and when the time difference is less than a first preset value, it is determined that the first SA cell is in an abnormal state. That is, after the electronic device establishes a network connection with the first SA cell, when it is released within a short time, it is determined that the first SA cell is in an abnormal state, thereby realizing determining whether the first SA cell is in an abnormal state based on the release status information.

[0048] Optionally, the release status information includes a release count, where the release count includes: the number of times the first PDU session between the electronic device and the first SA cell is released within a preset time period. Before establishing a network connection between the electronic device and the target cell, the method further includes:

[0049] Within the preset time period, upon receiving a first PDU session release command sent by the first SA cell, re-establishing the first PDU session with the first SA cell;

[0050] When the number of release times is greater than a second preset value, it is determined that the first SA cell is in an abnormal state.

[0051] The preset time period may be a relatively short time period, for example, 1-3 minutes. The preset number of times may be 3-5 times, that is, within a relatively short time period, the electronic device establishes a network connection with the first SA cell multiple times, and the multiple established network connections are all released. At this time, it can be determined that the first SA cell is in an abnormal state.

[0052] Specifically, see Figure 3 In one embodiment of the present disclosure, a network connection method is provided, which specifically includes the following steps:

[0053] Step S301: After the electronic device is stationed in the first SA cell, it establishes a data PDU and sends a PDU session establishment request (PDU SESSION ESTABLISH REQTEST request) to the base station of the first SA cell.

[0054] Step S302: The base station of the first SA cell sends a PDU session request accept message (PDU SESSION ESTABLISH ACCEPT message) to the electronic device in response to the PDU session establishment request to establish a network connection.

[0055] Step S303: When the PDU session release command is received for the first time, a second timer and a counter are started, wherein the timing duration of the second timer is the size of the preset time period, and the initial value of the counter is n=1;

[0056] Step S304: Send a PDU session establishment request to the base station of the first SA cell again;

[0057] Step S305: The base station of the first SA cell sends a PDU session request accept message to the electronic device in response to the PDU session establishment request;

[0058] Step S306: When a PDU session release command is received, the counter is incremented by 1, i.e., n=n+1;

[0059] Step S307: Determine whether the second timer has timed out; if the second timer has not timed out, return to step S304;

[0060] Step S308: When the second timer times out, determine whether n is less than or equal to the preset number of times; if so, stay normally;

[0061] Step S309: If n is greater than a preset number of times, it is determined that the first SA cell is in an abnormal state;

[0062] Step S310: Establish a network connection with the target cell, so as to access the Internet normally.

[0063] In this embodiment, by determining the number of times the first PDU session between the electronic device and the first SA cell is released within a preset time period, and when the number of releases is greater than a second preset value, it is determined that the first SA cell is in an abnormal state, that is, when the number of times the network connection between the electronic device and the first SA cell is released exceeds the set number within a short period of time, it is determined that the first SA cell is in an abnormal state, thereby realizing determining whether the first SA cell is in an abnormal state based on the release status information.

[0064] In one embodiment of the present disclosure, whether the first SA cell is in an abnormal state can be determined by simultaneously judging whether the first time difference is a first preset value and whether the number of releases is greater than a second preset value, wherein the first preset value is less than the duration of the preset time period, that is, the timing duration of the above-mentioned first timer is less than the timing duration of the second timer.

[0065] Optionally, the electronic device is pre-configured with frequency information of at least two candidate cells, the at least two candidate cells include at least one of a second SA cell and a Long Term Evolution (LTE) cell, and the target cell is any candidate cell of the at least two candidate cells, and establishing a network connection between the electronic device and the target cell includes:

[0066] A network connection with the target cell is established based on the frequency information of the target cell.

[0067] Specifically, since the coverage of adjacent cells of the same type usually has overlapping areas, and the coverage of cells of different types also has overlapping areas, when the electronic device is stationed in the first SA cell, it can also establish a network connection with other cells. The frequency of the candidate cells and the coverage of the candidate cells can be pre-configured in the electronic device. In this way, when the first SA cell is in an abnormal state, the electronic device can determine from the configuration information the at least two candidate cells that can normally provide network services for it, and can determine the target cell among the at least two candidate cells, and at the same time, establish a network connection with the target cell based on the frequency of the target cell, wherein the process of establishing a network connection between the electronic device and the target cell is similar to the above process, that is, by sending a PUD session creation request to the base station of the target cell, and after receiving the PUD session creation reception message sent by the base station of the target cell, the network connection process is completed.

[0068] In this implementation, by establishing a network connection between the electronic device and the target cell when the first SA cell is in an abnormal state, it can be ensured that Internet access services can be normally provided to the electronic device.

[0069] Optionally, before establishing the network connection between the electronic device and the target cell, the method further includes:

[0070] In a case where the at least two candidate cells include at least one second SA cell, determining the target cell among the at least one second SA cell;

[0071] In a case where the at least two candidate cells do not include the second SA cell, the target cell is determined in at least one LTE cell.

[0072] Among them, when the at least two candidate cells do not include the second SA cell, determining the target cell in at least one LTE cell can specifically refer to: when the at least two candidate cells do not include the second SA cell, and the at least two candidate cells include at least one LTE cell, determining the target cell in the at least one LTE cell.

[0073] Since the Internet access service provided by the SA cell is faster than that provided by the LTE cell, when the at least two candidate cells include the second SA cell, the target cell may be preferentially determined from the second SA cell to improve the quality of the network service. Accordingly, when the at least two candidate cells do not include the SA cell, the target cell is determined from the LTE cell to normally provide the network service to the electronic device.

[0074] Optionally, before establishing the network connection between the electronic device and the target cell, the method further includes:

[0075] Acquiring signal strength information of the at least two candidate cells;

[0076] The candidate cell with the strongest signal strength among the at least two candidate cells is determined as the target cell.

[0077] The electronic device may directly download the signal strength of the candidate cell.

[0078] In this implementation, the candidate cell with the strongest signal strength among the at least two candidate cells is determined as the target cell, which is beneficial to improving the quality of network services.

[0079] In another embodiment of the present disclosure, before establishing the network connection between the electronic device and the target cell, the method further includes:

[0080] In a case where the at least two candidate cells include at least two second SA cells, determining the second SA cell with the strongest signal strength among the at least two second SA cells as the target cell;

[0081] In a case where the at least two candidate cells do not include the second SA cell and the at least two candidate cells include at least two LTE cells, the LTE cell with the strongest signal strength among the at least two LTE cells is determined as the target cell.

[0082] Optionally, when it is determined based on the release status information that the first SA cell is in an abnormal state, the method further includes:

[0083] Add the first SA cell to the locally cached list of abnormal 5G SA cells.

[0084] Among them, the abnormal 5G SA cell list can cache the cell frequency information of the cells determined as abnormal cells by the electronic device within a preset time length. In this way, when the electronic device connects to the network, it can choose to establish a network connection with other cells outside the abnormal 5G SA cell list to improve the success rate of the network connection. It can be understood that the first SA cell only stores the cell frequency information of the cells determined as abnormal cells by the electronic device within the preset time length. The cells determined as abnormal by the electronic device will be removed from the abnormal 5G SA cell list when the preset time length is exceeded. In this way, it can be ensured that such cells can provide network services to the electronic device normally after returning to normal.

[0085] See Figure 4 , is a structural diagram of an electronic device 400 provided in an embodiment of the present disclosure, wherein the electronic device 400 includes:

[0086] An acquiring module 401 is configured to acquire release status information of a first protocol data unit (PDU) session when the electronic device 400 establishes a network connection with a first independent network (SA) cell, where the first PDU session is a PDU session between the electronic device 400 and the first SA cell;

[0089] The first determining module 403 is configured to determine that the first SA cell is in an abnormal state when the first time difference is less than a first preset value.

[0090] Optionally, the release status information includes a release count, where the release count includes: a number of times the first PDU session between the electronic device 400 and the first SA cell is released within a preset time period;

[0100] The electronic device 400 further includes:

[0102] In this embodiment, when the electronic device 400 establishes a network connection with the first SA cell, it is determined whether the first SA cell is in an abnormal state based on the release status information of the first PDU session, and when the first SA cell is in an abnormal state, a network connection between the electronic device 400 and the target cell is established to ensure that when the first SA cell is abnormal, the electronic device 400 can still connect to the network, thereby improving the network connection effect of the electronic device 400.
