In the embodiments of this application, in a case that an electronic device establishes a network connection to a first SA cell, whether the first SA cell is in an abnormal state is determined based on release status information of a first PDU session, and in a case that the first SA cell is in an abnormal state, a network connection between the electronic device and a target cell is established. In this way, because whether the first SA cell is in an abnormal state may be identified in a timely manner based on the release status information of the first PDU session, and in a case that it is recognized that the first SA cell is in an abnormal state, a network connection of the electronic device is switched to another cell, so that the electronic device stores a normal network connection.
The following describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application.
In the specification and claims of this application, the terms such as “first” and “second” are used for distinguishing similar objects, and are not necessarily used to describe a particular order or sequence. It should be understood that terms used in such a way are interchangeable in proper circumstances, so that embodiments of this application can be implemented in an order other than the order illustrated or described herein. Objects classified by “first”, “second”, and the like are usually of a same type, and a quantity of objects is not limited. For example, there may be one or more first objects. In addition, in this specification and the claims, “and/or” indicates at least one of connected objects, and a character “/” generally indicates an “or” relationship between associated objects.
A network connection method, an electronic device, a readable storage medium, and a chip provided in the embodiments of this application are described in detail below by using specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Step S101: In a case that the electronic device establishes a network connection to a first standalone 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.
Step S102: In a case that it is determined, based on the release status information, that the first SA cell is in an abnormal state, establish a network connection to a target cell, where the target cell is a cell other than the first SA cell.
The electronic device may be various types of User Equipment (UE) carried by a user. For ease of understanding, UE is used below to represent the electronic device.
The first SA cell may be a 5th Generation (5G) Mobile Communication Technology SA cell.
That the electronic device establishes a network connection to the first standalone SA cell may mean that the UE establishes a network connection to a base station corresponding to the first SA cell. A specific network connection process may be as follows:
The UE sends a PDU session establish request to the base station of the first SA cell, where the PDU session establish request is used to request to establish the first PDU session; and in response to the PDU session establish request, the base station of the first SA cell sends a PDU session establish accept message to the UE, where the PDU session establish accept message is a PDU session establish accept message. After the two steps, a process of completing the network connection of the UE is completed, that is, a process of establishing the first PDU session is completed. In this case, the UE may normally access the Internet.
When a large quantity of different UEs establish network connections to the base station of the first SA cell at a same time, because the first SA cell may be unable to simultaneously meet Internet access requirements of the large quantity of UEs, the first SA cell actively disconnects network connections of some UEs, that is, disconnects PDU sessions of some UEs. After the PDU session between the first SA cell and the UE is disconnected, a PDU release command PDU session release command is sent to the UE.
Based on this, in an embodiment of this application, the release status information may include the PDU release command. In addition, cases in which received PDU release commands are in a normal state of the SA cell and states in which received PDU release commands are in an abnormal state of the SA cell may be predefined. Then, whether the first SA cell is in an abnormal state may be determined based on the release status information.
It may be understood that, that the first SA cell is in an abnormal state may mean that the first SA cell itself is faulty, or may mean that the first SA cell is in an overloaded state because excessive UEs are connected to the first SA cell.
The target cell may be various cells other than the first SA cell that can provide a network service for the electronic device. The electronic device is located within network coverage of the target cell.
In this implementation, in a case that the electronic device establishes the network connection to the first SA cell, whether the first SA cell is in an abnormal state is determined based on the release status information of the first PDU session, and in a case that the first SA cell is in an abnormal state, the network connection between the electronic device and the target cell is established. In this way, because whether the first SA cell is in an abnormal state may be identified in a timely manner based on the release status information of the first PDU session, and in a case that it is recognized that the first SA cell is in an abnormal state, a network connection of the electronic device is switched to another cell, so that the electronic device stores a normal network connection.
For example, the release status information includes a first time difference, and the first time difference includes a time difference between a time point at which the first PDU session is established and a time point at which the first PDU session is released. Before the establishing a network connection to a target cell, the method further includes:
For example, a first timer may be preconfigured in the electronic device. When the electronic device receives the PDU session establish accept message, that is, when the electronic device successfully establishes the network connection to the first SA cell, the electronic device controls the first timer to start timing. When receiving the PDU session release command, that is, when disconnecting the network connection between the electronic device and the first SA cell, the electronic device controls the first timer to end timing. The first time difference may be obtained through reading of timing duration of the first timer.
It may be understood that the first time difference may be a relatively short time difference, for example, a value range of the first time difference may be 0 to 10 seconds. In other words, after the electronic device establishes the network connection to the first SA cell, the established network connection is immediately released by the first SA cell. In this case, it may be considered that the first SA cell is abnormal.
After camping on a first SA cell, an electronic device establishes a data PDU, and sends a PDU session establish request to a base station of the first SA cell.
The base station of the first SA cell sends a PDU session establish accept message to the electronic device in response to the PDU session establish request. After receiving the PDU session establish accept message, the electronic device starts a first timer.
Before the first timer expires, if a PDU session release command is not received, the electronic device normally camps on the first SA cell. Timing duration that is set by the first timer is a size of the first time difference.
Before the first timer expires, if the PDU session release command is received, it is determined that the first SA cell is in an abnormal state, and a network connection between the electronic device and a target cell is established.
It may be understood that, after the first timer expires, if a network connection between the electronic device and the first SA cell is released, it is considered that the network connection is normally released, that is, the first SA cell is in a normal state. In this case, after the electronic device establishes the network connection to the first SA cell again, and after the electronic device successfully establishes the network connection to the first SA cell, the electronic device starts the first timer to be perform timing again, and repeats the foregoing determining process. In other words, if the network connection between the electronic device and the first SA cell is released before the first timer expires, it is determined that the first SA cell is in an abnormal state.
In addition, in another embodiment of this application, whether the first timer expires may be determined after the PDU session release command is received, to determine whether the first SA cell is in an abnormal state. For example, after the PDU session release command is received, if the first timer has expired, it is determined that the first SA cell is in a normal state. Correspondingly, after the PDU session release command is received, if the first timer does not expire, it is determined that the first SA cell is in an abnormal state.
In this implementation, a time difference between a time point at which the first PDU session is established and a time point at which the first PDU session is released is determined, and in a case that 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 the network connection to the first SA cell and the network connection is released in a relatively short time, it is determined that the first SA cell is in an abnormal state. In this way, whether the first SA cell is in an abnormal state is determined based on the release status information.
For example, the release status information includes a quantity of releasing times, and the quantity of releasing times includes a quantity of times that the first PDU session between the electronic device and the first SA cell is released within a preset period of time. Before the establishing a network connection to a target cell, the method further includes:
The preset time period may be a relatively short time period, for example, may be 1 to 3 minutes. The preset quantity of times may be 3 to 5 times, that is, in a relatively short time period, the electronic device establishes a network connection to the first SA cell for a plurality of times, and network connections established in the plurality of times are all released. In this case, it may be determined that the first SA cell is in an abnormal state.
For example, as shown in
Step 301: After camping on a first SA cell, an electronic device establishes a data PDU, and sends a PDU session establish request to a base station of the first SA cell.
Step 302: The base station of the first SA cell sends a PDU session establish accept message to the electronic device in response to the PDU session establish request, to establish a network connection.
Step S303: Start a second timer and a counter in a case that a PDU session release command is received for a first time, where timing duration of the second timer is a size of the foregoing preset time period, and an initial value of the counter is n=1.
Step S304: Send a PDU session establish request to the base station of the first SA cell again.
Step S305: The base station of the first SA cell sends a PDU session establish accept message to the electronic device in response to the PDU session establish request.
Step S306: In a case that the PDU session release command is received, increase the counter by 1, that is, n=n+1.
Step S307: Determine whether the second timer expires, and return to perform step S304 in a case that the second time does not expire.
Step S308: In a case that the second timer expires, determine whether n is less than or equal to a preset quantity of times, and if yes, perform normal camping.
Step S309: If n is greater than the preset quantity of times, determine that the first SA cell is in an abnormal state.
Step S310: Establish a network connection to a target cell, to access the Internet normally.
In this implementation, a quantity of times that the first PDU session between the electronic device and the first SA cell is released within the preset time period is determined, and in a case that the quantity of releasing times is greater than a second preset value, it is determined that the first SA cell is in an abnormal state, that is, when a quantity of times that a network connection between the electronic device and the first SA cell is released exceeds a specified quantity of times in a relatively short time, it is determined that the first SA cell is in an abnormal state. In this way, whether the first SA cell is in an abnormal state is determined based on the release status information.
In an embodiment of this application, whether the first time difference is a first preset value and whether the quantity of releasing times is greater than the second preset value may be simultaneously determined, to determine whether the first SA cell is in an abnormal state, where the first preset value is less than duration of the preset time period, that is, timing duration of the first timer is less than timing duration of the second timer.
For example, the electronic device is preconfigured 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, the target cell is any candidate cell in the at least two candidate cells, and the establishing a network connection to a target cell includes:
For example, coverage ranges of neighboring cells of a same type usually have overlapping areas, and in addition, coverage ranges of cells of different types also have overlapping areas. Therefore, when the electronic device camps on the first SA cell, a network connection may be further established to another cell. A frequency of the candidate cell and a coverage range of the candidate cell may be preconfigured in the electronic device. In this way, when the first SA cell is in an abnormal state, the electronic device may determine, from configuration information, the at least two candidate cells that can normally provide a network service for the electronic device, and may determine the target cell from the at least two candidate cells. In addition, a network connection between the electronic device and the target cell is established based on a frequency of the target cell. A process of establishing the network connection between the electronic device and the target cell is similar to the foregoing process, that is, after a PUD session establish request is sent to a base station of the target cell, and a PUD session establish accept message sent by the base station of the target cell is received, a network connection process is completed.
In this implementation, in a case that the first SA cell is in an abnormal state, the network connection between the electronic device and the target cell is established. In this way, it can be ensured that an Internet access service can be normally provided for the electronic device.
For example, before the establishing a network connection to a target cell, the method further includes:
In some embodiments, the determining the target cell from at least one LTE cell in a case that the at least two candidate cells do not include the second SA cell may mean: determining the target cell from the at least one LTE cell in a case that the at least two candidate cells do not include the second SA cell and the at least two candidate cells include the at least one LTE cell.
In comparison with the LTE cell, an Internet access speed of an Internet access service provided by the SA cell is faster. Therefore, for example, in a case that the at least two candidate cells include the second SA cell, the target cell may be determined from the second SA cell, to improve network service quality. Correspondingly, in a case that the at least two candidate cells do not include the SA cell, the target cell is determined from the LTE cell, so that a network service can be normally provided for the electronic device.
For example, before the establishing a network connection to a target cell, the method further includes:
The electronic device may directly download signal strength of the candidate cell.
In this implementation, the candidate cell with the strongest signal strength in the at least two candidate cells is determined as the target cell. In this way, network service quality is improved.
In another embodiment of this application, before the establishing a network connection to a target cell, the method further includes:
For example, in a case that it is determined, based on the release status information, that the first SA cell is in an abnormal state, the method further includes:
The abnormal 5G SA cell list may cache frequency information of a cell that is determined by the electronic device as an abnormal cell within preset duration. In this way, when connecting to a network, the electronic device may choose to establish a network connection to a cell other than the abnormal 5G SA cell list, to improve a network connection success rate. It may be understood that the first SA cell stores only the frequency information of the cell that is determined by the electronic device as an abnormal cell within the preset duration, and after the preset duration, the cell that is determined by the electronic device as abnormal is removed from the abnormal 5G SA cell list. In this way, it can be ensured that after such a cell is recovered to normal, the cell can normally provide a network service for the electronic device.
For example, the release status information includes a first time difference, and the first time difference includes a time difference between a time point at which the first PDU session is established and a time point at which the first PDU session is released. As shown in
For example, the release status information includes a quantity of releasing times, and the quantity of releasing times includes a quantity of times that the first PDU session between the electronic device 400 and the first SA cell is released within a preset period of time;
For example, the electronic device 400 is preconfigured 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 in the at least two candidate cells; and
For example, the electronic device 400 further includes:
For example, the obtaining module 401 is further configured to obtain signal strength information of the at least two candidate cells; and
In this implementation, in a case that the electronic device 400 establishes the network connection to the first SA cell, whether the first SA cell is in an abnormal state is determined based on the release status information of the first PDU session, and in a case that the first SA cell is in an abnormal state, the network connection between the electronic device 400 and the target cell is established, to ensure that the electronic device 400 can still connect to a network in a case that the first SA cell is abnormal, thereby improving a network connection effect of the electronic device 400.
