Description

Cell access control method, base station, terminal and system

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a cell access control method, a base station, a terminal, and a system.

Background

During use, the mobile terminal needs to access to a suitable cell to initiate a communication service in the cell. With the continuous development of the mobile communication field, the types of carriers are also continuously increased, and some conventional terminals may not support the new type of carriers. Because the conventional terminal often cannot utilize the system gain brought by the new type of carrier, in order to avoid the terminal accessing a cell whose carrier is not supported, the cell access process of the terminal needs to be controlled.

In the existing cell access control method, a base station sends an access prohibition indication of a cell controlled by the base station through a broadcast message, and a terminal detects the setting of the access prohibition indication after receiving the broadcast message sent by the base station; if the access prohibition indication is set to be allowed, the terminal can initiate a cell access process to the base station; if the access prohibition indication is set as prohibition, the terminal does not initiate a cell access process to the base station.

In the process of implementing the invention, the inventor finds that the prior art has at least the following problems:

in the existing cell access control method, the cell prohibition indication of the existing cell access control method aims at all types of terminals, and the terminals cannot distinguish whether the terminals are suitable for accessing the cells corresponding to the base station, so that the performance gain of a new type of carrier waves on a system cannot be fully utilized, and the user experience is not high.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, a flowchart of a method for controlling cell access according to an embodiment of the present invention is shown, where the method is used for controlling a cell access process of a terminal in a base station. The cell access control method may include:

step 101, sending an access prohibition indication and a restricted access indication of a cell controlled by a base station to a terminal, so that the terminal selects to receive one or two of the access prohibition indication and the restricted access indication according to the terminal type of the terminal to confirm whether the cell allows the terminal to access; wherein, the terminal type includes: a first type terminal and a second type terminal; the access barring indication is used for indicating the cell access of the first type terminal, and the restricted access indication is used for indicating the cell access of the second type terminal.

In summary, in the cell access control method provided in the embodiment of the present invention, the base station sends the barring indication and the restrictive access indication of the cell controlled by the base station to the terminal, so that the terminal selects one or both of the barring indication and the restrictive access indication according to the terminal type of the terminal to detect whether the cell allows the terminal to access, thereby solving a problem that the terminal cannot distinguish whether the terminal is suitable for accessing the cell corresponding to the base station in the prior art, and achieving a purpose of fully utilizing a performance gain of a new type of carrier on a system and improving user experience.

Corresponding to the cell access control method described in fig. 1, please refer to fig. 2, which shows a flowchart of a method for controlling cell access according to an embodiment of the present invention, and the method can be applied to control cell access in a terminal. The cell access control method may include:

step 201, receiving an access barring indication and/or a restrictive access indication of a cell controlled by a base station, which is sent by the base station;

step 202, confirming whether the cell allows access according to the received access prohibition indication and/or restricted access indication;

step 203, if it is determined that the cell is allowed to access, the cell is regarded as a candidate cell; if the cell is confirmed not to allow the terminal to access, the cell is not considered as a candidate cell;

wherein, the terminal type of the terminal comprises: a first type of terminal and a second type of terminal.

In summary, in the cell access control method provided in the embodiment of the present invention, the terminal detects whether the cell allows the terminal to access by receiving the barring indication and the restrictive access indication of the cell controlled by the base station, and selecting one or both of the received barring indication and the restrictive access indication according to the type of the terminal to which the terminal belongs, so as to solve the problem that the terminal cannot distinguish whether the terminal is suitable for accessing the cell corresponding to the base station in the prior art, thereby achieving the purpose of fully utilizing the performance gain of a new type of carrier to a system and improving user experience.

For further description of the cell access control method shown in fig. 2, please refer to fig. 3, which shows a cell access control method according to another embodiment of the present invention, which can be applied to control cell access in a terminal. The cell access control method may include:

in step 301, the terminal receives an access barring indication and/or a restricted access indication of a cell controlled by a base station, which are sent by the base station.

The base station may set the barring access indication and the restrictive access indication according to the type of the carrier carried by the corresponding controlled cell. The terminal types include a first type terminal and a second type terminal, wherein the first type terminal may be a legacy type terminal and the second type terminal may be an enhanced type terminal.

If the terminal is the first type terminal, the terminal receives an access prohibition indication of a cell controlled by the base station sent by the base station, or receives an access prohibition indication and a restrictive access indication of a cell controlled by the base station sent by the base station. If the terminal is the second type terminal, the terminal receives a restrictive access instruction of a cell controlled by the base station sent by the base station, or receives an access prohibition instruction and a restrictive access instruction of a cell controlled by the base station sent by the base station.

Step 302, the terminal confirms whether the cell allows access according to the received access prohibition indication and/or restricted access indication;

in particular, the method comprises the following steps of,

if the base station is a first type terminal, the terminal detects the received access prohibition indication; if the access prohibition indication is set as permission, confirming that the cell is permitted to access; and if the access prohibition indication is set as prohibition, confirming that the cell does not permit access.

Wherein, the access prohibition indication and the restricted access indication can be set to two states: allow access and disallow access.

If the base station is a second type terminal and the terminal receives a restrictive access instruction of a cell controlled by the base station, which is sent by the base station, the terminal detects the received restrictive access instruction; if the restrictive access indication is set as allowed, confirming that the cell is allowed to access; and if the restrictive access indication is set as forbidden, confirming that the cell does not allow access.

If the base station is a second type terminal and the terminal receives the access prohibition indication and the restricted access indication of a cell controlled by the base station and sent by the base station, the base station is a second type terminal

The terminal detects the received access prohibition indication and the received restrictive access indication; if the access prohibition indication is set as access permission and the restrictive access indication is set as access permission, confirming that the cell is permitted to access; if the access prohibition indication and/or the restrictive access indication are set as access prohibition, confirming that the cell is not allowed to be accessed;

or, the terminal detects the received access prohibition indication; if the access prohibition indication is set as access permission, confirming that the cell is permitted to access; if the access prohibition indication is set as access prohibition, the restrictive access indication is further detected; if the restrictive access indication is set as the access permission, confirming that the cell is allowed to access; if the restrictive access indication is set as access prohibition, confirming that the cell is not allowed to access;

or, the terminal detects the received restrictive access indication; if the restrictive access indication is set as the access permission, confirming that the cell is allowed to access; if the restrictive access indication is access prohibition, further detecting the access prohibition indication; if the access prohibition indication is set as access permission, confirming that the cell is permitted to access; and if the access prohibition indication is set as access prohibition, confirming that the cell does not permit access.

Step 303, if it is determined that the cell allows access, the terminal regards the cell as a candidate cell; if the cell does not allow the terminal to access, the terminal does not regard the cell as a candidate cell;

and if the terminal confirms that the cell is allowed to be accessed, the cell is regarded as a candidate cell so that the terminal selects a suitable cell or a best cell which can reside in the cell selection and/or reselection process.

Further, if the terminal detects that the cell does not allow the terminal to access, the terminal continues to receive the access indication of other cells.

It should be noted that each cell corresponds to a respective frequency band. If the terminal detects that a cell does not allow the terminal to access, it needs to determine whether to select another cell in the same frequency band as the cell according to a certain rule, for example:

the access indication sent by the base station received by the terminal may further include an intra-frequency reselection indication (intrafreq reselection), where the intra-frequency reselection indication is used to indicate whether the terminal may select another cell that meets the reselection criterion and is in the same frequency band as the cell within a predetermined time. If the intra-frequency reselection indication is set to be allowed, the terminal may continue to select other cells meeting the reselection criterion in the same frequency band as the cell, otherwise, the terminal does not select other cells meeting the reselection criterion in the same frequency band as the cell within a predetermined time (for example, within 300 seconds).
