Description
Technical Field
The embodiment of the application relates to electronic technology, and relates to but is not limited to a method and a device for processing radio link failure, a terminal and a storage medium.
Background
An LTE (Long Term Evolution) Network is composed of an E-UTRAN (E-UTRAN, evolved Universal Terrestrial Radio Access Network) and an EPC (Evolved Packet switching center), and the Network is flat. The E-UTRAN is connected with the EPC through an S1 interface, consists of a plurality of interconnected eNBs (Evolved NodeBs), and all the eNBs are connected through an X2 interface. In an LTE network, due to factors such as a wireless environment or movement of a terminal (i.e., user equipment) in a network coverage area, an abnormal connection of the terminal may be caused, for example, RLF (Radio Link Failure) may occur in the terminal, thereby affecting a normal service of the terminal.
Currently, the conventional technology is based on a procedure specified by 3GPP (The 3rd generation partnership project), and when a terminal camps on an LTE cell and RLF occurs in a connected state, RRC (Radio Resource Control) re-establishment is performed and cell selection is performed again. However, if the network parameter configuration of the LTE cell in which the terminal resides is abnormal, RLF is easily caused to the terminal. According to the existing scheme, the terminal may continue to select the abnormal cell, and then the terminal always generates the RLF on the abnormal cell, thereby causing the problems of network card pause or silent conversation and the like.

In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no specific meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.

The embodiment of the present application provides a method for processing a radio link failure, where the method is applied to a terminal, and a function implemented by the method may be implemented by a processor in the terminal calling a program code, where of course, the program code may be stored in a storage medium of the terminal. Fig. 1 is a first schematic flow chart illustrating an implementation process of a method for handling a radio link failure according to an embodiment of the present application, as shown in fig. 1, the method includes:
step S101, acquiring the number of times of radio link failure of a terminal on a target service cell;
here, the terminal may be various types of devices having an information processing capability, such as a mobile phone, a tablet computer, a notebook computer, a fixed terminal such as a personal computer, a server cluster, and other computing devices having an information processing capability.
For each terminal attached to the network, a Mobility Management Entity (MME) serves the terminal, and the MME and the eNB are connected by using a control plane S1 interface (i.e., S1-MME interface). The S1-MME interface provides control plane services for the terminal, and comprises the functions of mobility management and bearing management.
In the embodiment of the present application, the target serving cell refers to a serving cell in which a terminal resides. The target serving cell may be a cell on a different base station, or may be a different cell on the same base station.
In the prior art, according to the 3GPP protocol, when the terminal camps on the LTE cell and RLF occurs while the terminal is in a connected state, RRC reestablishment is performed and cell selection is performed again. Therefore, for example, after the terminal camps in the target serving cell, the monitoring is performed, and when it is monitored that the terminal has RLF, it is considered that the terminal has a radio link failure in the target serving cell. When RLF occurs, the terminal performs cell selection again and performs RRC reestablishment according to the 3GPP protocol. And after the terminal selects to reside in the target serving cell again and RRC reestablishment is successful, if the terminal generates RLF again, the terminal is considered to generate two times of radio link failures on the target serving cell.
Step S102, if the times reach preset times, determining a first time point when the terminal firstly generates wireless link failure on the target service cell and a second time point when the times reach the preset times;
for example, if the preset number of times is set to 10, a time point at which the terminal has a radio link failure at 1 st time on the target serving cell and a time point at which the terminal has a radio link failure at 10 th time on the target serving cell are determined.
Step S103, if the time difference between the first time point and the second time point is less than a first preset time duration, adding the target serving cell to a forbidden cell list.
For example, if the first predetermined duration is 60 seconds and the predetermined number of times is 10, if the difference between the time point at which the radio link failure occurs 1 st time on the target serving cell and the time point at which the radio link failure occurs 10 th time on the target serving cell by the terminal is less than 60 seconds, it is considered that the RLF frequently occurs on the target serving cell, and thus the target serving cell is added to the forbidden cell list.
In the embodiment of the application, the times of the wireless link failure of the terminal on the target serving cell are obtained; if the times reach preset times, determining a first time point when the terminal firstly generates wireless link failure on the target service cell and a second time point when the times reach the preset times; and if the time difference between the first time point and the second time point is less than a first preset time length, adding the target serving cell into a forbidden cell list, so that a fault cell can be identified, and the problem of network abnormality or abnormal call caused by the fact that the terminal stays in the fault cell again when selecting the cell can be prevented in a mode of forbidding the fault cell, and the network stability of the terminal is improved.
Based on the foregoing embodiments, an embodiment of the present application further provides a method for processing a radio link failure, where the method includes:
step S111, acquiring the times of radio link failure of the terminal on a target service cell;
step S112, if the times reaches the preset times, determining a first time point when the terminal firstly generates the radio link failure on the target service cell and a second time point when the times reaches the preset times;
step S113, if the time difference between the first time point and the second time point is less than a first preset time length, adding the target serving cell into a forbidden cell list;
step S114, if the time difference between the first time point and the second time point is greater than or equal to the first preset time length, reacquiring the number of times that the terminal has a radio link failure on the target serving cell.
For example, if the first preset duration is 60 seconds and the preset number of times is 10 times, if the difference between the time point of the radio link failure occurring at the 1 st time on the target serving cell by the terminal and the time point of the radio link failure occurring at the 10 th time on the target serving cell by the terminal is greater than or equal to 60 seconds, it is determined that the RLF frequently occurs on the target serving cell by the terminal, and the terminal may continue to select to camp on the target serving cell. And, re-acquiring the number of times of radio link failure of the terminal on the target serving cell. That is, after the time taken for the terminal to generate RLF on the target serving cell 10 times is 60 seconds or more, the counting is restarted, and if the terminal generates RLF again thereafter, the counting is counted once and the retiming is started.
Based on the foregoing embodiment, an embodiment of the present application further provides a method for processing a radio link failure, and fig. 2 is a schematic view of an implementation flow of the method for processing a radio link failure in the embodiment of the present application, and as shown in fig. 2, the method includes:

step S204, if the time difference between the first time point and the second time point is greater than or equal to the first preset time length, the number of times of radio link failure of the terminal on the target serving cell is obtained again;
step S205, after the terminal executes the reconstruction of the radio resource control, determining whether the cell to be accessed by the terminal belongs to the forbidden cell list;
step S206, if the cell to be accessed by the terminal belongs to the forbidden cell list, reselecting the cell to be accessed by the terminal.
Here, after the terminal generates RLF and performs radio resource control reestablishment, it is determined whether a cell to be accessed by the terminal is in the forbidden cell list, and if the terminal selects the cell to be accessed to be in the forbidden cell list, cell selection is performed again to avoid the cells in the forbidden cell list.

step S222, if the terminal has a radio link failure in the target serving cell, starting to count the number of times of the radio link failure of the terminal in the target serving cell;
step S223, acquiring the number of times of wireless link failure of the terminal on the target service cell;
step S224, if the times reaches the preset times, determining a first time point when the terminal first generates a radio link failure on the target serving cell and a second time point when the times reaches the preset times;
step S225, if the time difference between the first time point and the second time point is less than a first preset time length, adding the target serving cell into a forbidden cell list;

step S231, if the radio resource control corresponding to the terminal is in a connection state, determining whether the terminal has a radio link failure on the target serving cell;
wherein it is determined that the terminal has a radio link failure on the target serving cell when one of the following conditions is satisfied:
the link quality corresponding to the target serving cell does not meet the requirement, and the duration of the link quality which does not meet the requirement exceeds a third preset duration; or the like, or, alternatively,

step S240, if the signal of the current serving cell of the terminal is smaller than a preset signal value, removing a part of cells or all cells in the forbidden cell list from the forbidden cell list.
Here, if the signal of the current serving cell of the terminal is smaller than a preset signal value, it indicates that the signal quality of the serving cell is poor, thereby causing poor network signal or call signal of the terminal. And removing part of or all cells in the forbidden cell list from the forbidden cell list so as to prevent the terminal from having no service problem caused by the fact that no service cell with better signal quality can reside.
Fig. 3A is a method for handling a radio link failure in the prior art, as shown in fig. 3A, the method includes:
step S31, the terminal is in an RRC connection state;
step S32, the terminal generates RLF;
step S33, the terminal executes RRC reestablishment;
step S34, the terminal performs cell selection and camps on LTE.
That is, after the terminal enters the RRC connected state on a cell, if RLF occurs (for example, the T310 and T312 timers are expired, or random access fails), the terminal performs RRC re-establishment and cell selection is resumed.
However, this has the following problems: if the network parameter configuration of the cell is abnormal, the terminal is easy to have RLF, and the terminal may continue to select the abnormal cell according to the existing scheme, so that the terminal is always in the abnormal cell RLF, thereby causing the problems of network card pause, silent conversation and the like.
Therefore, based on the foregoing embodiments, the present application further provides a method for handling a radio link failure. The method in the embodiment of the application can detect whether the LTE cell frequently generates the RLF, identify the cell frequently generating the RLF, and add the cell into the forbidden LTE cell list to prevent the fault cell frequently generating the RLF from residing when the cell selection is executed next time, thereby improving the network stability of the terminal.
First, a "forbidden LTE cell list" is maintained for storing cell information of the frequently occurring RLFs. Next, two variables are defined, one being the number Count and the other being the timer T. The variable Count indicates the number of RLFs occurring in a certain cell. And recording the time corresponding to the variable Count by the variable T. Again, two constants are defined, one constant MAX _ COUNT, and the other constant MAX _ T. The constant MAX _ COUNT represents the maximum preset number of RLF occurring in a certain cell, and the constant MAX _ T represents the maximum preset time corresponding to the RLF occurring in the certain cell reaching the maximum preset number. For example, the MAX _ COUNT may be 10 times, and the MAX _ T may be 60 seconds.
Correspondingly, fig. 3B is a schematic view of a third implementation flow of the method for processing a radio link failure according to the embodiment of the present application, and as shown in fig. 3B, the method for processing a radio link failure includes:
step S301, after the terminal enters the RRC connection state, starting to monitor whether RLF occurs in the target cell, and setting the initial value of the times Count to be 0;
step S302, if RLF occurs, the frequency Count is added with 1, and a timer T starts to Count time;
step S303, after RLF occurs, the terminal executes RRC reestablishment to recover RRC connection, and if RLF still occurs on the target cell subsequently, the frequency Count continues to be increased by 1;
step S304, if the number of times Count is equal to a constant MAX _ COUNT and the timer T is less than the constant MAX _ T, determining that the target cell belongs to a cell with high frequency RLF, and adding the target cell to a forbidden LTE cell list, so that the terminal does not continuously camp on the target cell when performing cell selection next time;
step S305, if the number of times Count is equal to the constant MAX _ Count and the timer T is greater than or equal to MAX _ T, it is determined that the target cell does not belong to a cell in which RLF occurs at a high frequency, and the variable Count and the variable T are reset to continue monitoring.
In the embodiment of the application, whether the LTE cell frequently generates the RLF is detected, the cell frequently generating the RLF is identified, the cell is added into a forbidden LTE cell list, and the terminal is prevented from residing on the cell frequently generating the RLF next time. Therefore, the fault cell can be identified according to the characteristic that RLF frequently occurs, the cell is prevented from residing again and having fault in the next cell selection, and the network stability of the terminal is improved.
Of course, a timer may be added in the above scheme to maintain the "forbidden LTE cell list," and when the timer expires, the cells in the "forbidden LTE cell list" are automatically removed. For example, if the timer setting time is 12 hours, then after 12 hours, all cells in the "forbidden LTE cell list" are released. Alternatively, the list can be actively released when the overall network signal is too poor, so as to avoid the out-of-service condition.
