Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for accessing a cell.
Background
In general, an operator may define a priority level of a cell in advance, so that when a mobile terminal performs cell reselection, a cell with the highest priority level may be preferentially selected to camp on, so as to keep a wireless network of the mobile terminal in an optimal state. After the mobile terminal resides in a certain cell, the mobile terminal acquires the adjacent cell list in the system message broadcast of the cell so as to monitor the signal change conditions of the currently residing cell and the adjacent cell, and performs cell reselection according to the priority level corresponding to each cell in the adjacent cell list, thereby ensuring that the mobile terminal always resides in the cell with better signals.
Since the bearer capability of each cell is limited, if the number of mobile terminals camped in a cell with the highest priority level is too large, the cell may be congested, so that other mobile terminals cannot access the cell. When the mobile terminal attempts to access the cell with the highest priority level, if the cell with the highest priority level is congested, the mobile terminal cannot access the cell. Because the mobile terminal will try to access the cell with the highest priority level when reselecting the cell next time, if the cell with the highest priority level is still in the congestion state, the mobile terminal can not access the cell, so that the mobile terminal can not successfully reselect the cell, and the mobile terminal always resides in the original cell with poor signal quality.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a flow chart illustrating a method of accessing a cell according to an example embodiment. As shown in fig. 1, the method for accessing a cell provided by the present disclosure may enable a mobile terminal to access a cell with the highest priority level and no congestion when performing cell reselection. The method comprises the following steps.
In step S11, when it is detected that the signal strength of the original cell currently camped on is lower than the first threshold, the cell with the highest priority in the cell list is determined as the target cell.
The method provided by the disclosure can be applied to a mobile terminal, and the mobile terminal can be a smart phone or a tablet computer and other devices. A cell refers to an area covered by a wireless signal in mobile communication, and generally refers to a range covered by a signal of a base station. There are many types of cells, for example, the cell may be an LTE cell (Long Term Evolution), a WCDMA cell (Wideband Code Division Multiple Access), a GSM cell (Global System for Mobile Communication), and the like. Of course, the cell may also be other types of cells, and is not described in detail herein.
The first threshold is a preset value, and the first threshold refers to a critical value for triggering the mobile terminal to perform cell reselection. When the mobile terminal detects that the signal strength is lower than the first threshold, it indicates that the signal strength of the original cell where the mobile terminal currently resides is very weak, and cell reselection is required.
For example: assuming that the normal range of signal strength is between 0dbm and-90 dbm, the first threshold may be set to-90 dbm, so that the mobile terminal may perform cell reselection when detecting that the signal strength of the original cell in which the mobile terminal currently resides is lower than-90 dbm.
The original cell periodically sends the cell list with the related information of the adjacent cell to the mobile terminal, so that the mobile terminal can perform cell reselection according to the information in the cell list. The cell list includes cells that can cover the mobile terminal and priority levels corresponding to the cells.
When the mobile terminal detects that the signal strength of the original cell where the mobile terminal currently resides is lower than the first threshold, it indicates that the signal provided by the original cell is very weak, and the mobile terminal needs to perform cell reselection. The mobile terminal determines the cell with the highest priority in the cell list as the target cell to be used as the candidate cell for cell reselection.
For example: assuming that the mobile terminal is a smart phone A, the smart phone A currently resides in a GSM cell, a first threshold is preset to-80 dbm, the GSM cell periodically sends a cell list with related information of adjacent cells to the mobile terminal, the cell list comprises an LTE cell, a WCDMA cell and a TSD cell, and the cell list has a priority level corresponding to each cell, wherein the LTE cell is a first priority level, the WCDMA cell is a second priority level, the TSD cell is a third priority level, and the priority levels are the first priority level, the second priority level and the third priority level from high to low in sequence. When the smart phone a detects that the signal strength of the currently camped GSM cell is-90 dbm and lower than a first threshold value-80 dbm, it indicates that the signal strength of the currently camped GSM cell of the smart phone a is very weak and cell reselection is required, so the smart phone a determines the LTE cell with the highest priority level in the cell list as the target cell to be used as the candidate cell for cell reselection.
In addition, since there are many ways to determine the cell with the highest priority in the cell list as the target cell, several implementations are described herein.
Briefly described below is an implementation of including at least two cells in a cell with the highest priority level, which may include the steps of: first, a cell list is obtained. And secondly, determining the cell with the highest priority in the cell list. And thirdly, when the cell with the highest priority level comprises at least two cells, randomly selecting one cell from the cells with the highest priority level as a target cell.
When the mobile terminal detects that the signal intensity of the original cell where the mobile terminal currently resides is lower than the first threshold, the mobile terminal needs to first acquire a cell list sent by the original cell in advance. The mobile terminal then determines the cell with the highest priority in the cell list. Finally, when the mobile terminal determines that the cell with the highest priority level comprises at least two cells, the mobile terminal can select one cell from the at least two cells, and in order to avoid the situation that the cell congestion occurs because all the mobile terminals select the cell with the highest signal quality in the cells with the highest priority level, the mobile terminal can randomly select one cell from the cells with the highest priority level as a target cell, so that the mobile terminal can be ensured to select different cells with good signal quality, the mobile terminal can normally perform cell reselection, and the pressure of the cell with the highest signal quality can be relieved.
Another implementation of including at least two cells in the cell with the highest priority level is briefly described below, which may include the following steps: first, a cell list is obtained. And secondly, determining the cell with the highest priority in the cell list. And thirdly, when the cell with the highest priority level comprises at least two cells, determining the cell with the highest signal strength in the cell with the highest priority level as a target cell.
When the mobile terminal detects that the signal intensity of the original cell where the mobile terminal currently resides is lower than the first threshold, the mobile terminal needs to first acquire a cell list sent by the original cell in advance. The mobile terminal then determines the cell with the highest priority in the cell list. Finally, when the mobile terminal determines that the cell with the highest priority level comprises at least two cells, the mobile terminal can select one cell from the at least two cells, and when the load pressure of the cell is lower, the mobile terminal can determine the cell with the highest signal strength in the cell with the highest priority level as a target cell so as to ensure that the mobile terminal has better signal quality.
In step S12, an access request is sent to the target cell.
After the mobile terminal determines the cell with the highest priority in the cell list as the target cell, the mobile terminal sends an access request to the target cell, so that the mobile terminal can camp on the target cell after the target cell is confirmed.
In step S13, when the target cell cannot be accessed, the priority level of the target cell in the cell list is modified to a preset level, which is lower than the highest priority level.
After the mobile terminal sends an access request to the target cell, the mobile terminal is in a state of waiting for accessing the target cell. When the target cell is in a congested state, the target cell cannot accept more access requests of the mobile terminal, so that the mobile terminal cannot access the target cell. When the target cell cannot be accessed, it is indicated that the target cell is not suitable for the mobile terminal to reside, so the mobile terminal needs to modify the priority level of the target cell in the cell list to a preset level. Since the priority level of the preset level is lower than the highest priority level, the target cell is not selected when the mobile terminal performs cell reselection next time.
For example: assuming that the mobile terminal is a smart phone A, the smart phone A currently resides in a GSM cell, the GSM cell periodically sends a cell list with related information of adjacent cells to the mobile terminal, the cell list includes an LTE cell, a WCDMA cell and a TSD cell, and the cell list has a priority level corresponding to each cell, wherein the LTE cell is a first priority level, the WCDMA cell is a second priority level, the TSD cell is a third priority level, and the priority levels are the first priority level, the second priority level and the third priority level in sequence from high to low. When the cell reselection is performed by the smart phone A, the smart phone A determines the LTE cell with the highest priority in the cell list as a target cell, and then sends an access request to the LTE cell. When the smart phone a cannot access the LTE cell, it is indicated that the LTE cell is in a congested state and is not suitable for the smart phone a to camp on, so that the smart phone a needs to modify the priority level of the LTE cell in the cell list from the first priority level to a third priority level, so that the LTE cell is not selected when the mobile terminal performs cell reselection next time.
In step S14, the cell with the highest priority in the cell list is determined as the designated cell.
After the mobile terminal modifies the priority level of the target cell in the cell list to the preset level, the mobile terminal needs to select the cell with the highest priority level again in the cell list, and determine the cell with the highest priority level selected this time as the designated cell to be used as the candidate cell for cell reselection.
In step S15, an access request is sent to the designated cell.
After the mobile terminal determines the cell with the highest priority in the cell list as the designated cell, the mobile terminal sends an access request to the designated cell, so that the mobile terminal can camp on the target cell after the designated cell is confirmed.
In the embodiment shown in fig. 1, when the mobile terminal performs cell reselection, an access request is sent to a target cell with the highest priority in the cell list, so as to facilitate access to the target cell. When the mobile terminal cannot access the target cell, it indicates that the target cell is in a congested state, and then the priority level of the target cell in the cell list needs to be modified to a preset level, so that the mobile terminal cannot access the target cell again when performing cell reselection next time, but accesses the specified cell with the highest priority level in the current cell list. Therefore, the scheme provided by the disclosure can enable the mobile terminal to access to the cell with the highest priority level and no congestion when the mobile terminal performs cell reselection, so as to ensure the signal quality of the mobile terminal.
Fig. 2 is a flowchart illustrating another method for accessing a cell according to an exemplary embodiment, and as shown in fig. 2, the method for accessing a cell shown in fig. 2 may be used in a mobile terminal. Fig. 2 is an alternative embodiment based on fig. 1, and in the embodiment shown in fig. 2, the same parts as those of the embodiment shown in fig. 1 can be introduced and explained with reference to the embodiment shown in fig. 1. The method shown in fig. 2 comprises the following steps.
In step S21, when it is detected that the signal strength of the original cell currently camped on is lower than the first threshold, the cell with the highest priority in the cell list is determined as the target cell.
In step S22, an access request is sent to the target cell.
In step S23, when the target cell cannot be accessed, the priority level of the target cell in the cell list is modified to a preset level, which is lower than the highest priority level.
In step S24, the cell with the highest priority in the cell list is determined as the designated cell.
In step S25, an access request is sent to the designated cell.
In step S26, the signal strength of the target cell in the cell list is acquired.
The priority level of the target cell in the cell list is modified to a preset level by the mobile terminal because the mobile terminal cannot be accessed into the target cell. However, it is possible that the target cell is in an idle state after a certain period of time, so the mobile terminal needs to acquire the signal strength of the target cell in the cell list to monitor the signal strength of the target cell in real time.
In step S27, when the signal strength of the target cell in the cell list is greater than the second threshold within the preset time period, the priority level of the target cell in the cell list is restored to the initial level.
The preset time period is a preset time period, and for example, the preset time period may be set to 10 minutes. Of course, different time periods may be set according to actual conditions.
The second threshold is a preset value, and the second threshold refers to a critical value at which the priority level of the target cell is restored to the initial level. For example: assuming a normal range of signal strengths between 0dbm and-90 dbm, the second threshold may be set to-60 dbm.
When the mobile terminal determines that the signal strength of the target cell in the cell list is greater than the second threshold value within the preset time period, it indicates that the target cell is no longer in the congestion state, and the target cell has the capability of accessing more mobile terminals at this time, so that the mobile terminal can restore the priority level of the target cell in the cell list to the initial level, so that the target cell is taken as a candidate cell when cell reselection is performed next time.
Fig. 3 is a flowchart illustrating a method for accessing a cell according to an exemplary embodiment, and as shown in fig. 3, the method for accessing a cell shown in fig. 3 may be used in a mobile terminal. Fig. 3 is an alternative embodiment based on fig. 1, and in the embodiment shown in fig. 3, the same parts as those of the embodiment shown in fig. 1 can be introduced and explained with reference to the embodiment shown in fig. 1. The method shown in fig. 3 comprises the following steps.
In step S31, when it is detected that the signal strength of the original cell currently camped on is lower than the first threshold, the cell with the highest priority in the cell list is determined as the target cell.
In step S32, an access request is sent to the target cell.
In step S33, when the target cell cannot be accessed, the priority level of the target cell in the cell list is modified to a preset level, which is lower than the highest priority level.
In step S34, the cell with the highest priority in the cell list is determined as the designated cell.
In step S35, an access request is sent to the designated cell.
In step S36, the signal strength of the target cell in the cell list is acquired.
The priority level of the target cell in the cell list is modified to a preset level by the mobile terminal because the mobile terminal cannot be accessed into the target cell. However, it is possible that the signal strength of the target cell is still low after a certain period of time, so the mobile terminal needs to acquire the signal strength of the target cell in the cell list to monitor the signal strength of the target cell in real time.
In step S37, when the signal strength of the target cell in the cell list is less than the third threshold within the preset time period, the target cell is deleted in the cell list.
The preset time period is a preset time period, and for example, the preset time period may be set to 1 hour. Of course, different time periods may be set according to actual conditions.
The third threshold is a preset value, and the third threshold refers to a critical value of deleting the target cell in the cell list. For example: assuming a normal range of signal strengths between 0dbm and-90 dbm, the third threshold may be set to-90 dbm.
When the mobile terminal determines that the signal strength of the target cell in the cell list within the preset time period is smaller than the third threshold, it indicates that the target cell is in a state with weak signal strength for a long time and is not suitable for being used as an alternative cell for cell reselection of the mobile terminal, so that the mobile terminal can delete the target cell in the cell list to avoid taking the target cell with weak signal strength as the alternative cell when the mobile terminal performs cell reselection next time.
Fig. 4 is a flowchart illustrating a method for accessing a cell according to an exemplary embodiment, where the method for accessing a cell shown in fig. 4 may be used in a mobile terminal, as shown in fig. 4. Fig. 4 is an alternative embodiment based on fig. 1, and in the embodiment shown in fig. 4, the same parts as those of the embodiment shown in fig. 1 can be introduced and explained with reference to the embodiment shown in fig. 1. The method shown in fig. 4 comprises the following steps.
In step S41, when it is detected that the signal strength of the original cell currently camped on is lower than the first threshold, the cell with the highest priority in the cell list is determined as the target cell.
In step S42, an access request is sent to the target cell.
In step S43, when the target cell cannot be accessed, the priority level of the target cell in the cell list is modified to a preset level, which is lower than the highest priority level.
In step S44, the cell with the highest priority in the cell list is determined as the designated cell.
In step S45, an access request is sent to the designated cell.
In step S46, the priority level of the target cell in the cell list is restored to the initial level after a preset time period.
The preset time period is a preset time period, and for example, the preset time period may be set to 20 minutes. Of course, different time periods may be set according to actual conditions.
And the mobile terminal can not access the target cell, so that the priority level of the target cell in the cell list is modified to a preset level by the mobile terminal. However, in general, after a period of time, the target cell is in an idle state, so the mobile terminal may restore the priority level of the target cell in the cell list to the initial level after a preset period of time, so that the target cell is taken as the candidate cell when performing cell reselection next time.
