Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a cell reselection method and a mobile terminal.
Background
In the current mobile communication technology, signals of other cells are measured and more appropriate cells are reselected under the condition that the quality of signals of an original resident cell is reduced and cannot meet service requirements due to the change of the position of a mobile terminal. And when the cells with different priorities all meet the reselection condition, reselecting the cell with high priority.
However, there is a conflict in the priorities configured between cells: for example, in the inter-frequency cells P and Q of LTE (Long Term Evolution), the Priority in the cell P is configured as Priority-P < Priority-Q, and the Priority in the cell Q is configured as Priority-Q < Priority-P, and when both cell signal strength commands are greater than the reselection threshold value, the mobile terminal always tends to reselect another cell different from the currently camped cell, that is, the mobile terminal frequently reselects between the two LTE cells. Therefore, due to the priority conflict between cells, the mobile terminal cannot stably reside in the cell with better service quality, and thus, the service is abnormal.

the first processing module is used for detecting whether the reselection priority configurations of the current service cell and the switchable cell conflict or not in the reselection process of the cell;
and the second processing module is used for determining that one of the current serving cell and the switchable cell is a resident cell according to a preset parameter if the reselection priority configuration of the current serving cell and the switchable cell conflicts, wherein the preset parameter is a parameter other than the reselection priority configuration parameter.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a cell reselection method according to an embodiment of the present invention includes:
In this step, in the reselection process of the cell, by detecting whether there is a conflict between the reselection priority configurations of the current serving cell and the switchable cell, the next step is executed when there is a conflict.
In this step, after detecting that there is a conflict between the reselection priority configurations of the current serving cell and the switchable cell in step 101, it is determined that one of the current serving cell and the switchable cell is a camped cell according to a preset parameter, and since the preset parameter is a parameter other than the priority configuration parameter, the reselection priority between the cells can be ignored for selecting the camped cell, so as to perform effective camping.
Thus, according to the above steps 101 and 102, the cell reselection method according to the embodiment of the present invention first detects whether there is a conflict between the reselection priority configurations of the current serving cell and the switchable cell during the cell reselection process, and then determines the residential cell by using the preset parameter when it is known from the detected result that there is a conflict between the reselection priority configurations of the current serving cell and the switchable cell, and performs residential selection by ignoring the reselection priority of the cell under the condition of the conflict between the reselection priorities because the preset parameter is a parameter other than the reselection priority configuration parameter, so as to stably reside on a cell with better service quality, avoid signal fluctuation, and avoid power consumption increase or abnormal service caused by the fact that the cell cannot enter an idle state due to signal fluctuation.
Taking cell a and cell B both in LTE (Long Term Evolution ) system as an example, as shown in fig. 2, S201, after the mobile terminal is powered on and initialized, accesses to cell a through processes of power-on cell selection/cell reselection, and the like, where reselection priority of cell a is configured as: Priority-A < Priority-B. As the mobile terminal moves, S202, it is detected that cell B having a higher reselection priority than cell a satisfies a reselection condition: selecting a receiving signal intensity value Srxlev > ThreshX and HighP by a cell; where ThreshX, HighP are the signal strength threshold values when reselecting to a cell with high reselection priority. Then, S203, it is detected whether there is a conflict between the reselection priority configurations of cell a and cell B by reading the reselection priority configuration of cell B. If the reselection priority of the cell B is configured as follows: and (3) if the Priority-B is less than the Priority-A, and the reselection Priority configuration of the cell A and the cell B conflicts, executing S204, and selecting the cell A or the cell B as a resident cell by using the preset parameters of the non-reselection Priority configuration parameters. If the reselection priority of the cell B is configured as follows: if Priority-B is greater than or equal to Priority-a, it may be determined that cell B is the camping cell, S205 is performed, the mobile terminal reselects to cell B, and maintains the normal camping state, and detects the next reselectable high reselection Priority cell, and of course, S202 is performed to perform inter-cell collision detection.
Specifically, step 102 includes:
if the switchable cell and the current service cell are cells of the same system, determining a cell with higher signal quality in the switchable cell and the current service cell as a resident cell according to the signal quality of the cell;
and if the switchable cell and the current service cell are cells of different systems, determining a cell with higher system priority as a resident cell in the switchable cell and the current service cell according to the system priority.
In this embodiment, the preset parameter is set according to whether the current serving cell and the switchable cell are cells of the same system, and if the switchable cell and the current serving cell are cells of the same system, the preset parameter is preferably signal quality, and when a resident cell is selected, a cell with higher signal quality in the switchable cell and the current serving cell can be determined as the resident cell; if the switchable cell and the current serving cell are cells of different systems, the preset parameter is preferably the system priority, and when the resident cell is selected, a cell with a higher system priority in the switchable cell and the current serving cell can be determined as the resident cell.
Assuming that the current serving cell X and the switchable cell Y with conflicting reselection priority configurations are cells of adjacent cells with the same radio access technology RAT and the same or different frequency, that is, a cell with high signal quality (such as high signal strength or large signal-to-noise ratio) can be selected to reside; if the current serving cell X and the switchable cell Y are cells of different RATs, a cell with a higher system priority is selected to camp on, for example, under the priority of 4G, even if the signal quality of a UTRAN (universal mobile telecommunications system Terrestrial Access Network) cell is higher than that of an LTE cell, the LTE cell is preferentially camped on.
On the basis of the foregoing embodiment, after step 102, the method for reselecting a cell according to the embodiment of the present invention further includes:
if the mobile terminal cannot camp on any one of the switchable cell and the current serving cell, re-determining the switchable cell;
and if the residence is successful, performing the next cell reselection based on the preset parameters.
The mobile terminal usually resides in a resident cell selected from the current serving cell and the switchable cell, and certainly, if the selected resident cell fails to reside, another cell is selected to reside, and if the cell residences all fail (the mobile terminal quickly passes through the current serving cell and the switchable cell), the determination of the switchable cell is performed again. If the selected resident cell is successful, the reselection priority parameter is ignored based on the preset parameter, and the next cell reselection is carried out.
More specifically, as shown in fig. 3, if the camping is successful, the step of performing the next cell reselection based on the preset parameters includes:
In this step, a target cell with a signal strength greater than a signal strength threshold or a signal-to-noise ratio greater than a signal-to-noise ratio threshold may be determined through neighbor cell measurement/inter-system inter RAT measurement, etc., so as to preferably select a cell suitable for camping. The target cell determined here is a cell satisfying normal reselection conditions, and may be a cell having a higher reselection priority than the current serving cell determined by the reselection priority.
In this step, after the target cell is determined in step 301, it is predicted whether ping-pong reselection will occur in the resident target cell, so as to execute the next step.
In this step, when the prediction result in step 302 indicates that no ping-pong reselection occurs, the target cell is determined to be the next resident cell; and when the prediction result shows that the ping-pong reselection occurs, determining one cell of the current serving cell and the target cell as a next resident cell according to preset parameters.
Thus, in the process of performing the next cell reselection through step 301-.
if the system priority of the target cell is smaller than that of the current service cell, determining that ping-pong reselection exists in the target cell; or
And if the reselection priority configurations of the target cell and the current service cell conflict, determining that ping-pong reselection exists in the target cell.
Here, when the system priority of the target cell is smaller than the system priority of the current serving cell, or when the reselection priority configurations of the target cell and the current serving cell conflict, it can be determined that ping-pong reselection occurs in the target cell, otherwise, the target cell can be considered that ping-pong reselection does not occur in the target cell if none of the above conditions is met. Of course, if there are other optimization rules in the mobile terminal, the target cell is switched to the current serving cell when the mobile terminal resides in the target cell, and whether ping-pong reselection occurs needs to be further determined in combination with whether the target cell satisfies the optimization rules.
In this embodiment, in order to better record the cell selection state of the mobile terminal, a state machine is provided, which includes three states: 1. in a Normal State, a cell in which the mobile terminal resides last time and a cell in which the mobile terminal resides currently do not conflict in the Normal State, and cell reselection next time can be performed according to an original standard flow; 2. a Conflict State Conflict State, wherein the Conflict State indicates that the current cell to be reselected and the previous resident cell have reselection priority Conflict; 3. and keeping a State Hold State, wherein the State indicates that the reselection condition of the conflicting reselection priorities is in a limiting State, and the reselection priority parameters are temporarily stored and forbidden until other normal cells are resident. When the mobile terminal is started up and initialized, the State machine is set to be NormalState, after the fact that the reselection Priority configuration of the current service cell and the reselection Priority configuration of the switchable cell Conflict is detected, the State machine is switched to be Conflict State, resident cell selection is conducted only according to preset parameters, at the moment, the reselection Priority identification Hold _ Priority _ Flag can be set to be True, the current service cell and the switchable cell are updated with the same reselection Priority, and the situation that resident cannot be stably conducted is avoided. Then, if the residence of all cells fails, the State machine switches to the Normal State, and re-determines the switchable cell, and of course, Hold _ Priority _ Flag under the Normal State is False; if the State machine is successfully resided, the State machine is switched to the Hold State, the Hold _ Priority _ Flag is still True at this time, the reselection Priority is continuously ignored, and the residence selection is carried out only according to the preset parameters. If the target cell does not have ping-pong reselection, changing Hold _ Priority _ Flag to False, switching the State machine to Normal State, and residing the mobile terminal in the target cell; if the ping-pong reselection occurs in the target cell, the target cell is added into the candidate handover cell which ignores the reselection priority, the reselection priority is continuously ignored, and the resident selection is performed only according to the preset parameters.
In summary, in the cell reselection method according to the embodiment of the present invention, first, in a cell reselection process, whether a reselection priority configuration of a current serving cell and a switchable cell conflicts or not is detected, and then when it is known from a detection result that the reselection priority configuration of the current serving cell and the switchable cell conflicts, a residential cell is determined by using a preset parameter, and because the preset parameter is a parameter other than the reselection priority configuration parameter, the residential cell is selected by ignoring the reselection priority of the cell in the case of the reselection priority conflict, so that the residential cell stably resides on a cell with better service quality, and signal fluctuation is avoided, and power consumption increase or abnormal service caused by the fact that the cell cannot enter an idle state due to signal fluctuation is avoided.
