[0023] 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, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present disclosure as detailed in the appended claims.

[0024] The terms used in the disclosed embodiments are only for the purpose of describing specific embodiments and are not intended to limit the disclosed embodiments. The singular forms of "a" and "the" used in the disclosed embodiments and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0025] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the disclosed embodiments, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other.

Depending on the context, the words "if" and "if" as used herein may be interpreted as "at" or "when" or "in response to determination".

[0026] To facilitate understanding, the background technology involved in this application is first introduced.

[0027] With the continuous development of communication technology and the gradual enhancement of mobile communication technology, network equipment can send cell switching conditions and reconfiguration messages carrying switching target cell configurations to the terminal in advance. When the communication signal meets the above switching conditions, the terminal triggers conditional switching and switches the terminal's current service cell to the switching target cell.

[0028] If the signal strength detected by the terminal does not meet the conditional switching trigger condition, the terminal will not actively switch to other cells with better signals until the signal quality continues to deteriorate and the wireless link fails, triggering the reconstruction process. During the cell selection process of the reconstruction process, a cell with a stronger signal is selected.

[0029] Therefore, in order to solve the problems existing in the related technology and avoid triggering the reconstruction process, the present disclosure proposes a network switching method, which presets a third preset value and determines that the first measurement value of the service cell is lower than the third preset value, thereby determining that the signal quality of the current service cell is poor, so that the terminal can actively switch from the service cell to the switching target cell when the conditional switching is not met, thereby improving the terminal communication quality and stability.

[0030] Before introducing the detailed solution of the present disclosure, the scenario to which the solution of the present disclosure is applied is described first.

[0031] In some optional embodiments, the terminal for executing the present method may be at least one of a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

[0032] In some embodiments, the terms "terminal", "terminal device", "user equipment (UE)", "user terminal" "mobile station (MS)", "mobile terminal (MT)", subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device (mobile device), wireless device (wireless device), wireless communication device (wireless communication device), remote device (remote device), mobile subscriber station (mobile subscriber station), access terminal (access terminal), mobile terminal (mobile terminal), wireless terminal (wireless terminal), remote terminal (remote terminal), handset (handset), user agent (user agent), mobile client (mobile client), client (client) and the like can be used interchangeably.

[0033] It can be understood that the description of the embodiments of the present disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the network switching method, device and storage medium proposed in the embodiments of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0034] Figure 1 The flowchart of a network switching method provided by an embodiment of the present disclosure is executed by a terminal. Figure 1 As shown, the network switching method includes steps 101-103.

[0035] Step 101: obtain one or more first messages and determine one or more candidate target cells.

[0036] In some embodiments, the terminal may obtain one or more first messages sent by the network device, and determine one or more candidate target cells for cell switching when a preset condition is met.

[0037] In some embodiments, the terminal may determine one or more candidate target cells based on the second message embedded in the first message, but is not limited thereto. The terminal may also determine one or more candidate target cells by separately acquiring the second message. For a detailed description of the second message, see step 201, which will not be repeated here.

[0038] In some embodiments, the first message may be a reconfiguration message, such as a Radio Resource Control Reconfiguration (RRCReconfiguration) message.

[0039] In some embodiments, the first message includes a first information element, wherein the first information element is used to indicate that a cell switch is to be performed on the terminal when a preset condition is met.

[0040] In some embodiments, the first information element may be a conditional reconfiguration information element.

[0041] In some embodiments, the preset condition is that a first measurement value of the serving cell is lower than a first preset value and a second measurement value of the candidate target cell is higher than a second preset value, wherein the serving cell is a cell currently providing communication services to the terminal.

[0042] In some embodiments, the first preset value may be a measurement value of a serving cell when the terminal can perform cell switching in a standard protocol, but is not limited thereto and may also be a preset value.

[0043] In some embodiments, the second preset value may be a measurement value of a candidate target cell when the terminal can perform cell switching in a standard protocol, but is not limited thereto and may also be a preset value.

[0044] In some embodiments, the first measurement value and / or the second measurement value includes: at least one of: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RPRQ), and Signal to Interference plus Noise Ratio (SINR).

[0045] In some embodiments, when the terminal is able to communicate stably, the cell providing service can be measured, and the lowest RSRP, RSRQ, and SINR values ​​obtained by the measurement can be determined as the second preset values, or values ​​higher than the above-mentioned lowest RSRP, RSRQ, and SINR values ​​can be determined as the second preset values, but not limited to this. The present disclosure does not limit the method for determining the second preset value.

[0046] Step 102: Determine that a first measurement value of a serving cell is lower than a third preset value.

[0047] In some embodiments, the terminal determines that the first measurement value of the service cell is lower than the third preset value, thereby determining that although the service cell does not meet the conditions for cell switching, the communication quality provided by the service cell is poor, which lays the foundation for the terminal to actively switch cells and avoids further deterioration of communication quality and triggering the reconstruction process.

[0048] In some embodiments, the third preset value may be a local preset value configured in the terminal, wherein the third preset value is used to determine the communication or signal quality of the service cell. When the first measurement value is higher than or equal to the third preset value, the signal quality of the service cell is considered to be good; when the first measurement value is lower than the third preset value, the signal quality of the service cell is considered to be poor.

[0049] In some embodiments, the third preset value is higher than the first preset value, but is not limited thereto, and may also be lower than or equal to the first preset value. The present disclosure does not limit the relationship between the third preset value and the first preset value.

[0050] For example, the first measurement value of the service cell of the terminal is lower than the first preset value in the preset conditions issued by the network, but the measurement value of the candidate target cell is lower than the second preset value in the preset conditions. At this time, the preset conditions for conditional switching are still not met. The terminal can determine that the signal quality of the service cell is poor by determining that the first measurement value of the service cell is lower than the set third preset value, and actively seek for a target candidate cell with better signal quality to perform cell switching to ensure the terminal communication quality.

[0051] In some embodiments, the communication signal of the service cell can be tested, and the lowest RSRP, RSRQ, and SINR values ​​measured when stable communication can be performed can be determined as the third preset value. The third preset value can also be determined by other methods. The present disclosure does not limit the method for determining the third preset value.

[0052] Step 103: determine a handover target cell from one or more candidate target cells, and handover the serving cell to the handover target cell.

[0053] In some embodiments, the terminal determines a switching target cell from one or more candidate target cells, thereby switching the serving cell to the switching target cell, thereby enabling the terminal to actively switch when the communication quality of the serving cell is poor but does not meet the cell switching conditions specified in the protocol, thereby improving the quality and stability of terminal communication.

[0054] In some embodiments, a switching target cell can be determined from candidate target cells whose second measurement value is higher than a fourth preset value, so that the terminal can perform cell switching when the above-mentioned preset conditions are not met, wherein the relationship between the fourth preset value and the second preset value is not limited, that is, the fourth preset value can be greater than, less than or equal to the second preset value. The specific description can be found in step 205, which will not be repeated here.

[0055] In some embodiments, the communication signal of the candidate target cell can be tested, and the lowest RSRP, RSRQ, and SINR values ​​measured when stable communication can be performed can be determined as the fourth preset value. The fourth preset value can also be determined by other methods. The present disclosure does not limit the method for determining the fourth preset value.

[0056] In some embodiments, the candidate target cell with the highest second measurement value is determined as the switching target cell; or, the switching target cell is randomly determined from the candidate target cells with second measurement values ​​higher than a fourth preset value, which is not limited in the present disclosure.

[0057] In summary, according to the network switching method proposed in the present disclosure, the method is executed by the terminal, including: obtaining one or more first messages, and determining one or more candidate target cells, the first message includes a first information element, the first information element is used to indicate that the terminal is to perform cell switching when a preset condition is met, the preset condition is that the first measurement value of the service cell is lower than the first preset value and the second measurement value of the candidate target cell is higher than the second preset value; determine that the first measurement value of the service cell is lower than the third preset value; determine the switching target cell from one or more candidate target cells, and switch the service cell to the switching target cell. This method determines that the first measurement value of the service cell is lower than the third preset value, thereby determining that although the signal of the current service cell does not meet the conditions for cell switching, the communication quality of the service cell is poor, so that the terminal actively switches from the service cell to the switching target cell when the switching conditions are not met, thereby improving the communication quality and stability of the terminal and avoiding triggering the reconstruction process due to poor communication quality.

[0058] Figure 2 A schematic diagram of a network switching method proposed in an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, in Figure 1 Based on the illustrated embodiment, it is further explained that the method is executed by a terminal and includes steps 201-205.

[0059] Step 201, obtaining a second message.

[0060] In some embodiments, the terminal may obtain a second message sent by the network device to determine the reconfiguration information of the candidate target cell.

[0061] In some embodiments, the second message may be reconfiguration information for indicating a candidate target cell, such as a radio resource control condition reconfiguration (condRadio Resource ControlReconfiguration, condRRCReconfig) message.

[0062] In some embodiments, the second message includes a second information element, which can be used to indicate reconfiguration synchronization information of the candidate target cell, such as a synchronous reconfiguration (reconfigurationWithSync) information element.

[0063] In some embodiments, the second information element may include a physical cell address (Physical Cell Identifier, PCI) and other parameters that may indicate a cell address.

[0064] In some embodiments, the network device may embed the second message in the first message, that is, send the second message and the first message to the terminal at the same time. In other words, the terminal may obtain the second message and the first message at the same time, that is, step 201 and step 202 are performed simultaneously.

[0065] In some embodiments, the network device may send the first message and the second message to the terminal respectively, that is, the terminal may obtain the first message and the second message respectively.

[0066] Step 202: Obtain one or more first messages and determine one or more candidate target cells.

[0067] In some embodiments, the terminal may obtain one or more first messages, and determine one or more candidate target cells based on a second message embedded in the first message or a second message obtained separately.

[0068] For example, the terminal obtains an RRCReconfiguration message in which a condRRCReconfig message is embedded. The terminal may determine a candidate target cell based on the PCI indicated by the reconfigurationWithSync information element in the condRRCReconfig message.

[0069] In the present disclosure, the principle of step 202 is the same as Figure 1 Step 101 in the embodiment shown is the same as that in the embodiment shown in FIG. Figure 1 The relevant description will not be repeated here.

[0070] Step 203: Save the first information element and the second information element to a first variable list of the terminal.

[0071] In some embodiments, the terminal may save the first information element and the second information element to a first variable list of the terminal to maintain relevant information of the cell switching, that is, the first variable list may include one or more candidate target cells.

[0072] In some embodiments, the first variable list is used for cell reconfiguration.

[0073] In some embodiments, the first variable list may be a conditional reconfiguration variable table (VarConditionalReconfig) in the terminal.

[0074] Step 204: Determine second measurement values ​​of one or more candidate target cells based on a second information element in the first variable list.

[0075] In some embodiments, the terminal may determine one or more candidate target cells based on the second information element in the first variable list, thereby measuring the candidate target cells to determine second measurement values ​​of the one or more candidate target cells.

[0076] In some embodiments, the second measurement value includes: at least one of: a reference signal received power RSRP, a reference signal received quality RPRQ, and a signal to interference plus noise ratio SINR.

[0077] Step 205: Determine a handover target cell from candidate target cells whose second measurement value is higher than a fourth preset value.

[0078] In some embodiments, the terminal determines a switching target cell from candidate target cells whose second measurement value is higher than a fourth preset value, thereby laying a foundation for the terminal to perform cell switching.

[0079] In some embodiments, the fourth preset value may be a local preset value configured in the terminal, wherein the fourth preset value is used to determine the communication or signal quality of the candidate target cell. When the second measurement value is higher than the fourth preset value, the signal quality of the candidate target cell is considered to be better.

[0080] In some embodiments, the relationship between the fourth preset value and the second preset value is not limited. For example, when the measurement value of the candidate target cell is lower than the second preset value, but still can provide stable communication services, the fourth preset value may be less than or equal to the second preset value. For example, when the measurement value of the candidate target cell is higher than the second preset value, but still cannot provide stable communication services, the fourth preset value may be greater than the second preset value.

[0081] In some embodiments, the terminal may determine the candidate target cell with the highest second measurement value as the switching target cell, provided that the second measurement value is higher than a fourth preset value.

[0082] In some embodiments, the terminal also randomly determines a switching target cell from candidate target cells whose second measurement value is higher than a fourth preset value.

[0083] It should be understood that any of the above steps 201-205 may be omitted or replaced in different embodiments. That is, in the absence of contradiction, the above steps may be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples may be arbitrarily combined and may be arbitrarily combined with other implementation methods or embodiments.

[0084] In summary, according to the network switching method proposed in the present disclosure, the method is executed by the terminal, and the method includes: obtaining a second message, the second message is used to indicate the reconfiguration information of the candidate target cell; obtaining one or more first messages, and determining one or more candidate target cells, the first message includes a first information element, the first information element is used to indicate that the terminal is to perform cell switching when a preset condition is met, and the preset condition is that the first measurement value of the serving cell is lower than the first preset value and the second measurement value of the candidate target cell is higher than the second preset value; saving the first information element and the second information element to the first variable list of the terminal, the first variable list is used for cell reconfiguration; based on the second information element in the first variable list, determining the second measurement value of one or more candidate target cells; determining the switching target cell from the candidate target cells whose second measurement value is higher than the fourth preset value. The method disclosed in the present disclosure presets the third preset value and the fourth preset value, so that the terminal can actively perform cell switching when the serving cell and the candidate target cell do not meet the preset conditions for cell switching sent by the network device, thereby improving the communication quality and stability of the terminal and avoiding triggering the reconstruction process due to poor communication quality.

[0085] This solution enables the terminal to determine the submission of cell switching by obtaining a first message; determines a candidate target cell by obtaining a second message; determines that the communication quality of the service cell is poor by determining that the first measurement value of the service cell is lower than a third preset value; and determines that the candidate target cell has a second measurement value greater than a fourth preset value, so that the terminal determines the switching target cell, so that when the service cell and / or the candidate target cell do not meet the preset conditions for cell switching sent by the network device, the terminal actively performs cell switching, thereby improving the communication quality and stability of the terminal and avoiding triggering a reconstruction process due to poor communication quality.

[0086] Therefore, this solution has the following beneficial effects:

[0087] 1. For terminals that can perform cell switching under preset conditions, when the communication signal of the serving cell is poor but its signal strength does not meet the preset conditions for cell switching, it can actively switch to a candidate target cell with a better signal, thereby improving the communication quality and avoiding problems such as network freezes caused by the terminal in a serving cell with a poor signal.

[0088] 2. It can prevent the terminal from being in a cell with poor signal because the signal quality continues to deteriorate until the wireless link fails, triggering the reconstruction process, thereby avoiding the adverse effects caused by reconstruction, such as excessive signaling interaction, high latency, low recovery link efficiency, and poor user experience.
