[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] The cell reconstruction method provided in this application embodiment can be applied to, for example... Figure 1 The application environment is shown. Base station 104 is a device deployed in the access network to provide wireless communication functionality to terminal 102. In systems employing different wireless access technologies, the name of the device with base station functionality may differ. For example, in LTE systems, it is called an evolved Node B (eNodeB) or eNB; in 5G New Radio (NR) systems, it is called a gNodeB or gNB. Wireless communication can occur between terminal 102 and base station 104. Terminal 102 can be a smartphone, tablet, personal computer, laptop, wearable device, vehicle-mounted device, etc., and base station 104 can be any type of base station device, such as a macro base station, micro base station, or pico base station.

[0032] Generally, the downlink out-of-sync state determination of the terminal at the network side involves the following timers and constants: N310, T310 and N311, wherein N310 indicates the maximum number of downlink out-of-sync indications received by the terminal, T310 is a timer indicating that the terminal monitors the radio link failure, and N311 indicates the maximum number of downlink in-sync indications received by the terminal. These timers and constants can be configured to the terminal by dedicated signaling, for example, the timers and constants can be configured to the terminal by the signaling RLF-TimersAndConstants IE, or the timers and constants can be configured to the terminal by the parameters in the system broadcast (SIB1), for example, the timers and constants can be configured to the terminal by the parameters ue-TimersAndConstants IE in the system broadcast.

[0033] When the terminal performs radio link detection, if the number of downlink out-of-sync indications continuously received by the radio resource control layer (RRC layer) of the terminal is equal to N310, the timer T310 is triggered to start. If the number of downlink in-sync indications continuously received during the continuous process of the timer T310 is equal to N311, the timer T310 is stopped, indicating that the radio link synchronization has been restored. If the timer T310 expires, it is considered that the terminal is in a downlink out-of-sync state, that is, the terminal has a radio link failure (RLF). Further, when the terminal determines that the RLF occurs, the terminal starts the timer T311 and performs cell search and cell selection, as shown in Figure 2 If a suitable cell is found before the timer T311 expires, the terminal initiates an RRC connection reestablishment process to the cell, otherwise, the terminal enters an RRC_IDLE state. After entering the RRC_IDLE state, the RRC layer triggers the NAS layer to initiate a location update process to attempt to restore the RRC connection. However, in the conventional technology, the basis for the terminal to select a reestablishment cell during the RRC connection is the adjacent cell configuration or the historical cell from the network, and however, there is a problem of a high probability of reestablishment failure.

[0034] Based on the above problems, as shown in Figure 3 , a cell reestablishment method is provided. The cell reestablishment method is applied to the terminal in Figure 1 for example, and the cell reestablishment method comprises the following steps.

[0035] S201, in the case that the terminal is in a radio link failure (RLF), determining a target type of the RLF according to configuration information of a target cell.

[0036] In the process that the terminal establishes a communication connection with the base station, the base station reports configuration information to the terminal. Optionally, in this embodiment, the terminal can acquire configuration information of a target cell based on the configuration information reported by the base station when the terminal is in a radio link failure (RLF) state. It can be understood that the target cell in this embodiment is a cell that can establish a communication connection with the terminal. Optionally, in this embodiment, the target type of the RLF of the terminal can include permanent failure and non-permanent failure. Further, the terminal can determine the target type of the RLF according to whether the configuration information of the target cell is configuration information that violates a specified protocol. For example, if the configuration information of the target cell is configuration information that violates a specified protocol, the terminal can determine that the target type of the RLF is permanent failure. If the configuration information of the target cell is configuration information that does not violate a specified protocol, the terminal can determine that the target type of the RLF is non-permanent failure. For example, in this embodiment, taking the RRC reconfiguration parameter of the configuration information of the target cell as an example, if the terminal fails to detect the legality of the RRC reconfiguration parameter IE, the terminal can determine that the target type of the RLF is permanent failure according to the configuration information.

[0037] S202, based on the target type, disabling the target cell when it is determined that the target cell meets a preset disabling condition.

[0038] Optionally, in this embodiment, the disabling conditions of the target cells corresponding to different target types are also different. For example, if the target type is permanent failure, the disabling condition of the corresponding target cell can be that the number of reestablishment signaling sent within a preset time interval is greater than a preset number threshold. If the target type is non-permanent failure, the disabling condition of the corresponding target cell can be that the number of reestablishment signaling sent within a preset time interval is less than a preset number threshold. In this embodiment, the terminal can determine whether the target cell meets the disabling condition corresponding to the target type of the RLF based on the disabling condition. Optionally, in this embodiment, the cell disabling time corresponding to different target types is also different. In this embodiment, the terminal can disable the target cell within the cell disabling time corresponding to the target type when it is determined that the target cell meets the preset disabling condition based on the target type of the RLF. For example, taking the disabling time corresponding to permanent failure as 14400s and the disabling time corresponding to non-permanent failure as 7200s as an example, if the terminal determines that the target type of the RLF is permanent failure, the terminal can disable the target cell within 14400s after it is determined that the target cell meets the preset disabling condition. If the terminal determines that the target type of the RLF is non-permanent failure, the terminal can disable the target cell within 7200s after it is determined that the target cell meets the preset disabling condition.

[0039] It should be noted that in the embodiment, the disabled target cell is still effective in the process that the terminal is in the flight mode and the network initiatively configures the redirection, and the state of the disabled target cell can be cleared and the disabled target cell is invalid only in the case that the user restarts the terminal through the key of the terminal. In addition, after the target cell is disabled due to the preset disabling condition, the request of re-searching the network in the disabled cell initiated by the NAS layer is cleared after the request is received, but the terminal can be allowed to re-try the current disabled cell once, so as to prevent the case that no cell can be selected in the case that the timer does not expire.

[0040] S203, performing cell reestablishment based on the cell other than the target cell.

[0041] It should be noted that the cell reestablishment in the embodiment refers to the process that the terminal establishes a communication connection with the cell other than the target cell. Alternatively, the terminal can perform cell search and cell selection in the cell other than the target cell, and if a cell capable of establishing a communication connection is found in the cell other than the target cell before the timer T311 expires, the terminal initiates an RRC connection reestablishment process to the cell and performs cell reestablishment. Alternatively, in the embodiment, the terminal can perform cell search and cell selection based on the priority of the cell other than the target cell to find a cell capable of establishing a communication connection.

[0042] In addition, it should be noted that the cell reestablishment method provided in the embodiment of the application can be applied to various communication systems, for example, a New Radio (NR) system, an evolved system of the NR system, a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an Advanced Long Term Evolution (6LTE-A) system, or other communication systems, and the like.

[0043] In the cell reestablishment method, when the terminal is in a radio link failure, the target type of the radio link failure can be determined according to the configuration information of the target cell, so that the target cell can be disabled when the target cell meets the preset disabling condition according to the target type of the radio link failure. The target cell that is disabled cannot participate in the selection and reestablishment of the cell again, which avoids the terminal repeatedly reestablishing on the target cell that is disabled, leading to the failure of the terminal reestablishment. Therefore, the terminal can reestablish the cell based on other cells except the target cell, and the signal quality of the other cells is better than that of the target cell. Therefore, the method ensures the success rate of the terminal reestablishment and reduces the probability of the failure of the terminal reestablishment.

[0044] In the scenario of disabling the target cell when the target cell meets the preset disabling condition, it is necessary to determine whether the target cell meets the preset disabling condition based on the target type of the radio link failure. Optionally, in an embodiment, if the target type of the radio link failure is permanent failure, the target cell is disabled when the target cell meets the preset disabling condition, as shown in the following table. Figure 4 The method further includes the following steps.

[0045] S301, if the target type is permanent failure, the number of reestablishment signaling sent in a preset first time interval is obtained.

[0046] If the target type is permanent failure, the target cell cannot establish a communication connection under the target type, the target cell cannot participate in the selection and reselection of the cell, and the target cell is not allowed to be measured as a target measurement cell in the connected state. Optionally, in this embodiment, if it is determined that the target type of the radio link failure of the terminal is permanent failure, a timer can be started, and the number of reestablishment signaling sent by the terminal is obtained in a first time interval monitored by the timer. For example, in this embodiment, the preset first time interval can be 60s, and the terminal can monitor the number of reestablishment signaling sent by the terminal in 60s from the start time of the timer.

[0047] S302, determining whether the target cell meets the disabling condition according to the number of reestablishment signaling.

[0048] Optionally, in the embodiment, the acquired number of reestablishment signaling and the preset first number threshold can be compared to obtain a comparison result, and the comparison result is used to determine whether the target cell satisfies the disabling condition. Further, as an optional implementation, if the terminal determines that the comparison result is that the number of reestablishment signaling is greater than the preset first number threshold, the terminal can determine that the target cell satisfies the disabling condition. Taking the preset first time interval as 60s and the preset first number threshold as 3 times as an example, if the terminal determines that the target type of the RLF is permanent failure according to the configuration information of the target cell, and starts the timer, and the number of reestablishment signaling sent by the terminal monitored in 60s is 4 times, that is, the number of reestablishment signaling sent by the terminal monitored in 60s is greater than the preset first number threshold, it can be determined that the target cell satisfies the disabling condition at this time.

[0049] In the embodiment, in the case that the target type of the RLF occurred by the terminal is permanent failure, the process of acquiring the number of reestablishment signaling sent in the preset first time interval is relatively simple, so that whether the target cell satisfies the disabling condition can be quickly determined according to the number of reestablishment signaling sent by the terminal in the first time interval, and the efficiency of determining whether the target cell satisfies the disabling condition is improved, so that when it is determined that the target cell satisfies the preset disabling condition, the target cell is disabled, so that the disabled target cell can no longer participate in the selection and reestablishment of the cell, and the situation that the terminal repeatedly reestablishes on the disabled target cell and leads to the failure of the terminal reestablishment is avoided.

[0050] In the above scenario of disabling the target cell when it is determined that the target cell satisfies the preset disabling condition, it is necessary to determine whether the target cell satisfies the preset disabling condition based on the target type of the RLF. Optionally, in one embodiment, if the target type of the RLF is non-permanent failure, as shown in the embodiment, in one embodiment, the above method further includes: Figure 5

[0051] S401, if the target type is non-permanent failure, the signal strength of the target cell and the number of reestablishment signaling sent in the preset first time interval are acquired.

[0052] ​If the target type is non-permanent failure, it can be characterized that the target cell under the target type can establish a communication connection, but there can be a connection failure, so that the target cell cannot participate in cell selection and reselection, and as a target measurement cell in the connected state is not allowed to measure. Optionally, in this embodiment, if it is determined that the target type of the RLF occurred by the terminal is non-permanent failure, the terminal can determine the signal strength of the target cell according to the communication signal sent by the target cell, and start a timer to obtain the number of reestablishment signaling sent by the terminal in a first time interval monitored by the timer. Exemplarily, in this embodiment, the preset first time interval can be 60s, or 90s, etc., which is not limited in this embodiment.

[0053] S402, determining whether the target cell satisfies the disabling condition according to the signal strength and the number of reestablishment signaling.

[0054] Optionally, in this embodiment, the signal of the target cell can be a strong signal or a weak signal, that is, the signal strength of the target cell can be greater than a preset strength threshold or less than or equal to the preset strength threshold. Further, the disabling condition corresponding to the case that the signal strength of the target cell is greater than the preset strength threshold can be different from the disabling condition corresponding to the case that the signal strength of the target cell is less than or equal to the preset strength threshold. Next, how to use the number of reestablishment signaling sent in the above first time interval to determine whether the target cell satisfies the disabling condition when the signal strength of the target cell is greater than the preset strength threshold and when the signal strength of the target cell is less than or equal to the preset strength threshold will be described respectively:

[0055] Firstly, if the signal strength of the target cell is greater than the preset strength threshold, determining whether the target cell satisfies the disabling condition can include:

[0056] Step A, determining whether the number of reestablishment signaling is greater than a preset second number threshold.

[0057] Optionally, in the embodiment, the second threshold of times can be less than the first threshold of times. For example, the first threshold of times can be 3, and the second threshold of times can be 2. Alternatively, the first threshold of times and the second threshold of times can have other values, which are not limited in the embodiment. Optionally, in the embodiment, the terminal can compare the number of times of the reestablishment signaling with the second threshold of times, to determine whether the number of times of the reestablishment signaling is greater than the second threshold of times. Alternatively, the terminal can take the difference between the number of times of the reestablishment signaling and the second threshold of times, to determine whether the number of times of the reestablishment signaling is greater than the second threshold of times according to whether the difference is negative. Alternatively, the terminal can take the ratio between the number of times of the reestablishment signaling and the second threshold of times, to determine whether the number of times of the reestablishment signaling is greater than the second threshold of times according to whether the ratio is greater than 1.

[0058] In step B, if the number of times of the reestablishment signaling is greater than the second threshold of times, the terminal adjusts the signal receiving power value of the target cell to the first power value in a preset second time interval. If the number of times of the reestablishment signaling sent in the second time interval is greater than a preset third threshold of times, it is determined that the target cell satisfies the disabling condition.

[0059] Optionally, in the embodiment, the second time interval can be 600s, 800s, or the like, and the first power value can be 6db or other power values. In the embodiment, if the terminal determines that the number of times of the reestablishment signaling sent in the first time interval is greater than the second threshold of times, the terminal can adjust the signal receiving power value of the target cell to the first power value according to the difference between the current signal receiving power value and the first power value, and maintain the signal receiving power value of the target cell as the first power value in the preset second time interval. Further, after the signal receiving power value of the target cell is adjusted to the first power value in the second time interval, the terminal can obtain the number of times of the reestablishment signaling sent in the second time interval, and then compare the number of times of the reestablishment signaling sent in the second time interval with the preset third threshold of times. If the number of times of the reestablishment signaling sent in the second time interval is greater than the third threshold of times, it is determined that the target cell satisfies the disabling condition. Optionally, the third threshold of times in the embodiment can be equal to the second threshold of times, or can be greater than the second threshold of times, or can be less than the second threshold of times. The embodiment does not limit the value of the third threshold of times. For example, the value of the third threshold of times can be the same as the value of the second threshold of times, such as 2.

[0060] In the embodiment, when the signal strength of the target cell is greater than the preset strength threshold, the terminal can quickly determine whether the number of the reestablishment signaling sent in the first time interval is greater than the second number threshold by comparing the number of the reestablishment signaling sent in the first time interval with the second number threshold, thereby improving the determination efficiency. In the case that the number of the reestablishment signaling sent in the first time interval is greater than the second number threshold, the signal receiving power value of the target cell can be quickly adjusted to the first power value in the preset second time interval, and in the case that the number of the reestablishment signaling sent in the second time interval is greater than the third number threshold, it is determined that the target cell satisfies the preset disabling condition. In the process, the calculation amount is small, the determination process is simple, and in the case that the target type of the RLF of the target cell is non-permanent failure and the signal strength of the target cell is greater than the preset strength threshold, the number of the reestablishment signaling sent in the first time interval is used to quickly determine whether the target cell satisfies the preset disabling condition, thereby improving the efficiency of determining whether the target cell satisfies the preset disabling condition.

[0061] The second: if the signal strength of the target cell is less than or equal to the preset strength threshold, determining whether the target cell satisfies the disabling condition can include:

[0062] Step C, determining whether the number of the reestablishment signaling is greater than the third number threshold.

[0063] Optionally, in the embodiment, the third number threshold can have the same value as the first number threshold, for example, the first number threshold and the third number threshold can both have a value of 3, or the third number threshold can have the same value as the second number threshold, for example, the second number threshold and the third number threshold can both have a value of 2, which is not limited in the embodiment. Optionally, in the embodiment, the terminal can directly compare the number of the reestablishment signaling with the third number threshold to determine whether the number of the reestablishment signaling is greater than the third number threshold, or the terminal can take the difference between the number of the reestablishment signaling and the third number threshold to determine whether the number of the reestablishment signaling is greater than the third number threshold according to whether the difference is negative, or the terminal can take the ratio between the number of the reestablishment signaling and the third number threshold to determine whether the number of the reestablishment signaling is greater than the third number threshold according to whether the ratio is greater than 1.

[0064] Step D, if the number of the reestablishment signaling is greater than the third number threshold, the signal receiving power value of the target cell is adjusted to the second power value in the preset third time interval; and in the case that the number of the reestablishment signaling sent in the third time interval is greater than the fourth number threshold, it is determined that the target cell satisfies the disabling condition.

[0065] Optionally, in the embodiment, the third time interval can be 600s, 700s, or the like, and the second power value can be 3db, or the like, or other power values, and it should be noted that the second power value is less than the first power value. In the embodiment, if the terminal determines that the number of reestablishment signaling sent in the first time interval is greater than the third threshold, the terminal can adjust the signal receiving power value of the target cell to the second power value according to the difference between the current signal receiving power value and the second power value, and keep the signal receiving power value of the target cell as the second power value in the preset third time interval. Further, after adjusting the signal receiving power value of the target cell to the second power value in the third time interval, the terminal can obtain the number of reestablishment signaling sent in the third time interval, and then compare the number of reestablishment signaling sent in the third time interval with the fourth threshold. If the number of reestablishment signaling sent in the third time interval is greater than the fourth threshold, it is determined that the target cell meets the disabling condition. Optionally, the fourth threshold in the embodiment can be equal to the third threshold, or greater than the third threshold, or less than the third threshold, and the embodiment does not limit the value of the fourth threshold. For example, the value of the fourth threshold can be the same as the value of the third threshold, such as both being 2.

[0066] In the embodiment, if the signal strength of the target cell is less than or equal to the preset strength threshold, the terminal can quickly determine whether the number of reestablishment signaling sent in the first time interval is greater than the third threshold by comparing the number of reestablishment signaling sent in the first time interval with the third threshold, thereby improving the determination efficiency. Further, if the number of reestablishment signaling sent in the first time interval is greater than the third threshold, the signal receiving power value of the target cell can be quickly adjusted to the second power value in the preset third time interval, and if the number of reestablishment signaling sent in the third time interval is greater than the fourth threshold, it is determined that the target cell meets the preset disabling condition. In this process, the calculation amount is small, and the determination process is simple. If the target type of the RLF of the target cell is non-permanent failure and the signal strength of the target cell is less than or equal to the preset strength threshold, the terminal can quickly determine whether the target cell meets the preset disabling condition according to the number of reestablishment signaling sent in the first time interval, thereby improving the efficiency of determining whether the target cell meets the preset disabling condition.

[0067] In the scenario of disabling the target cell when it is determined that the target cell meets the preset disabling condition, the target cell can be disabled based on the disabling duration corresponding to the target type of the RLF of the target cell. In an embodiment, the disabling of the target cell in S202 includes disabling the target cell based on the disabling duration corresponding to the target type.

[0068] Optionally, the target type of the RLF of the target cell can include any one of permanent failure and non-permanent failure, wherein the disabling duration corresponding to the permanent failure is greater than the disabling duration corresponding to the non-permanent failure. That is, in this embodiment, if the target type of the RLF of the target cell is permanent failure, the terminal can disable the target cell using the disabling duration corresponding to the permanent failure; if the target type of the RLF of the target cell is non-permanent failure, the terminal can disable the target cell using the disabling duration corresponding to the non-permanent failure.

[0069] In order to facilitate the understanding of those skilled in the art, the core parameters involved in the process of disabling the target cell are illustrated by Table 1 as follows:

[0070] Table 1

[0071]

[0072] As shown in Table 1, exemplarily, when the target type of the RLF occurring in the target cell is permanent failure, the terminal can acquire the number of times of sending the reestablishment signaling in a preset first time interval, if the number of times of sending the reestablishment signaling in the first time interval is greater than a first number threshold (bar_threshold) 3 times, the terminal can determine that the target cell satisfies the disabling condition, and disable the target cell within 14400s; when the target type of the RLF occurring in the target cell is non-permanent failure, and the signal strength of the target cell is greater than or equal to a preset strength threshold 105dbm, i.e., the target type of the RLF occurring in the target cell is non-permanent failure-strong signal, the terminal can acquire the number of times of sending the reestablishment signaling in the first time interval, if the number of times of sending the reestablishment signaling in the first time interval is greater than a second number threshold (offset_threshold) 2 times, the terminal can adjust the signal receiving power of the target cell to a first power value (offset_penalty) 6db within a preset second time interval (offset_time) 600s, and determine whether the number of times of sending the reestablishment signaling in the second time interval is greater than a preset third number threshold (bar_threshold) 2 times, if yes, it can be determined that the target cell satisfies the disabling condition, and the target cell is disabled within 14400s; when the target type of the RLF occurring in the target cell is non-permanent failure, and the signal strength of the target cell is less than a preset strength threshold 105dbm, i.e., the target type of the RLF occurring in the target cell is non-permanent failure-weak signal, the terminal can acquire the number of times of sending the reestablishment signaling in the first time interval, if the number of times of sending the reestablishment signaling in the first time interval is greater than a third number threshold (offset_threshold) 3 times, the terminal can adjust the signal receiving power of the target cell to a second power value (offset_penalty) 3db within a preset third time interval (offset_time) 600s, and determine whether the number of times of sending the reestablishment signaling in the third time interval is greater than a preset fourth number threshold (bar_threshold) 2 times, if yes, it can be determined that the target cell satisfies the disabling condition, and the target cell is disabled within 7200s.

[0073] In the embodiment, the terminal disables the target cell based on the disabling duration corresponding to the target type of the RLF occurring in the target cell, which can disable the target cell within the corresponding disabling duration for different target types, avoids the problem that the target cell cannot participate in cell reselection due to long-time disabling, and ensures the availability of the target cell.

[0074] For the convenience of those skilled in the art, the cell reestablishment method provided in the present application is described in detail in combination with a complete embodiment as follows:
