The method for barring access to a cell provided by the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings through some embodiments and application scenarios.

As shown in Figure 2, this embodiment of the present application provides a method for barring access to a cell, and the method may include the following steps 201 to 203.

201. The network device sends a broadcast message.

The broadcast message is used to indicate that a device with N antennas is prohibited from accessing the first cell, and the first cell is a serving cell of the network device. Wherein, N is a positive integer.

Wherein, the broadcast message is used to instruct the terminal equipment including N antennas to search for a cell satisfying the camping condition from other cells other than the first cell.

Optionally, N is 1, or N is 2.

202. The terminal device receives the broadcast message sent by the network device.

In the embodiment of the present application, the terminal device includes N antennas.

203. The terminal device searches for a cell satisfying the camping condition from other cells other than the first cell.

It can be understood that satisfying the residency condition means satisfying the residency S criterion. For the description of the residency S criterion, reference may be made to existing related technologies, and details are not repeated here. A cell that meets the residency conditions means that the mobile terminal can obtain normal communication services in the cell, such as making voice calls and sending short messages. The signal quality meets certain requirements, the PLMN to which it belongs is the PLMN selected by the mobile terminal or the Equivalent Public Land Mobile Network (EPLMN for short), and the PLMN or EPLMN is not within the prohibited routing location area, such A cell can be regarded as a cell that satisfies the camping condition.

In this embodiment of the application, the network device notifies the terminal device that the first cell is a cell that is prohibited from accessing by devices with N antennas by broadcasting a message. Therefore, in the case that the terminal device is a device including N antennas, the terminal device searches for a target cell that satisfies the camping condition from other cells other than the first cell based on the broadcast message (for allowing a device with N antennas to access Incoming cell), after searching for the target cell, perform access in the target cell, so as to avoid the failure of accessing the first cell, which leads to a decline in the access success rate.

Optionally, the broadcast message carries a target identifier, and the target identifier is used to indicate that devices with N antennas are prohibited from accessing the first cell.

Exemplarily, the target identifier may be cellAccessBarForSingleAntUE, and the value may be set to TRUE.

Optionally, in the case that the first cell is not a cell prohibited from being accessed by devices with N antennas, the broadcast message may not carry the target identifier, or may carry the target identifier, but the value is set to FALSE.

In the embodiment of the present application, the target identifier can be assembled in the broadcast message. After receiving the broadcast message, the terminal device can obtain the target identifier by parsing the broadcast message, so as to obtain that the first cell is a cell prohibited from accessing by devices with N antennas. It is simple and convenient to indicate that devices with N antennas are prohibited from accessing the first cell through the target identifier, and there are few changes to broadcast messages.

Optionally, the broadcast message is a system message (System Information Blocks, SIB). For example, SIB1, SIB2 or SIB3, etc.; the broadcast message can also be a paging message, etc., which is not limited in the embodiment of the present application.

In the embodiment of this application, the broadcast message is preferably SIB1, because this system message is the first system message sent by the network device, and the terminal device has a higher probability of receiving SIB1.

Optionally, after the terminal device receives the broadcast message, it sets the first cell as a cell that the terminal device is prohibited from accessing, and when searching for a cell that meets the camping condition, it selects the first cell from other cells except the first cell. search.

Optionally, after the terminal device receives the broadcast message, if the searched cell that satisfies the camping condition is the first cell, it is prohibited from accessing the first cell, and searches for other cells that meet the camping condition again.

Exemplarily, referring to FIG. 2, as shown in FIG. 3, before the above step 203, the method for barring access to a cell provided in the embodiment of the present application may further include the following step 204.

204. When the searched cell that meets the camping condition is the first cell, the terminal device prohibits access to the first cell according to the broadcast message.

It can be understood that, after the terminal device determines that the searched cell that meets the camping condition is the first cell, access to the first cell is prohibited, so as to avoid access failure.

Optionally, referring to FIG. 3 , as shown in FIG. 4 , after the above step 202, the method for barring access to a cell provided in the embodiment of the present application may also include the following step 205.

205. The terminal device records the first cell as a cell prohibited from being accessed by a device with N antennas.

In this way, the terminal device can learn that the first cell is a cell that is prohibited from being accessed by devices with N antennas without receiving the broadcast message again subsequently.

Optionally, the above step 205 may specifically be implemented through the following step 205a.

205a. The terminal device adds the cell information of the first cell to the target list.

Wherein, the target list includes a plurality of cell information, and each cell information in the target list is used to indicate a cell that a terminal device with N antennas is prohibited from accessing.

In this embodiment of the present application, the first cell is recorded as a cell prohibited from accessing devices with N antennas by adding the cell information of the first cell to the target list, which is convenient for operation and convenient for terminal device management.

Optionally, the cell information of the first cell includes any of the following: frequency point information of the first cell and an ID card ID of the first cell; frequency point information of the first cell and a primary scrambling code.

In the embodiment of the present application, the cell information of the first cell is used to uniquely indicate the first cell. The frequency point information and the first cell ID of the first cell may uniquely indicate the first cell, and the frequency point information and the primary scrambling code of the first cell may also uniquely indicate the first cell. The embodiment of this application provides a variety of cell information recording methods, which can be set according to usage requirements in actual use.

Optionally, the first cell may be a cell where devices with N antennas are permanently prohibited from accessing, or the load of network devices in the first cell is greater than or equal to the first load threshold, and the first cell is set to prohibit N antennas When the load of the first cell is less than the second load threshold, the first cell is set as a cell that allows devices with N antennas to access. The second load threshold is less than or equal to the first load threshold.

Optionally, referring to FIG. 4, as shown in FIG. 5, before the above step 201, the method for barring access to a cell provided in the embodiment of the present application may also include the following step 206.

206. When detecting that the load of the first cell is greater than or equal to the load threshold, the network device generates the broadcast message.

Wherein, the load threshold in step 206 is recorded as the first load threshold, and the first load threshold and the second load threshold can be determined according to actual usage requirements, which are not limited in this embodiment of the present application.

In this embodiment of the application, the network device sets whether the first cell allows devices with N antennas to access according to the load of the first cell, so that network resources can be allocated more reasonably according to network configuration or network resource conditions, avoiding network The waste of resources makes the deployment of network resources more flexible and reasonable. At the same time, it also allows the terminal to choose to access other more preferred cells to provide better services for the terminal.

Optionally, in this embodiment of the present application, after the above step 206, when the network device detects that the load of the first cell is less than the second load threshold, the network device may send a new broadcast message, and the new broadcast disappears. Indicates that devices with N antennas are prohibited from accessing the first cell. Then, after a terminal device including N antennas receives the above-mentioned new broadcast message, if the terminal device previously recorded that the first cell is a cell that prohibits devices with N antennas from accessing, the terminal device deletes the record, and when the terminal device is turned on In scenarios such as restarting or mobile disconnection, when the terminal device detects that the first cell satisfies the camping condition, the terminal device may access the first cell.

Exemplarily, the method for barring access to a cell provided in the embodiment of the present application is exemplarily described below by taking N as 1 and the broadcast message as SIB1 as an example.

The network device then broadcasts SIB1.

The terminal device receives SIB1, then obtains the content of the SIB1 message body, and parses the parameter information in the SIB1 message; when the cell access related information (cellAccessRelatedInfo) in the parsed SIB1 contains the cellAccessBarForSingleAntUE parameter configuration, and the value is TRUE, the terminal device considers The first cell is a cell prohibited from being accessed by a single-antenna device, and then the first cell is recorded (recorded as a cell prohibited from being accessed by a single-antenna device), and notified to the upper layer of the terminal device. When the terminal device is a single-antenna device, the terminal device searches for other cells that meet the camping conditions except the first cell for access.

Exemplarily, the following is the SIB1 message:
