Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, a base station, and a storage medium for activating a composite cell in case of transmission link abnormality.
Background
In the initial stage of the fifth generation mobile communication (5G), in order to rapidly push 5G into the market, an operator generally uses a Non-independent Networking (NSA) mode as a transition first, and then transitions to a cell sharing one of an independent networking (SA) and a composite networking (NSA & SA), and a base station of the NSA & SA composite cell becomes a main stream.
A user terminal accessing a cell requires that the cell to be accessed is in an active state, and that the cell is able to communicate with the core network in order to obtain the required service.
In the cell activation strategy, an NSA cell can communicate with a 4G core network through a fourth generation mobile communication (4G) base station only by establishing a Dual Connectivity (endec) transmission link, and the NSA cell can be directly activated without other limitations without a separate transmission link to the core network; the SA cell needs to establish an NG transmission link to Access control and mobility Management Function (AMF) to communicate with the 5G core network, the activation of the SA cell is bound to the NG transmission link, i.e. the activation of the SA cell is allowed only under the condition that at least one NG link is established, and the deactivation of the SA cell is performed after the last NG link is broken, so that the situation that the SA user terminal accesses the SA cell but no core network provides service can be avoided. The activation/deactivation scheme of the NSA & SA composite cell is the same as that of the SA cell.
Therefore, in the NSA & SA composite cell mode, once the NG link is broken down, the NR cell cannot be activated, and not only the SA cell cannot be normally accessed, but also the NSA user cannot be normally accessed, which causes the network coverage to be seriously affected, and also seriously affects the user experience.
In view of this, when a transmission link is abnormal, how to improve the network coverage becomes a technical problem to be solved urgently.

Detailed Description
The embodiment of the invention provides a method for activating a composite cell under the condition of transmission link abnormality, a base station and a storage medium, which are used for solving the technical problem that the network coverage is small when the transmission link is abnormal in the prior art.
In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:
a method for activating a composite cell under the condition of transmission link abnormity is provided, which is applied to setting a base station in composite networking, wherein a non-independent networking NSA and an independent networking SA share the cell in the composite networking, and the method comprises the following steps: periodically detecting the current connection state of the transmission link; the transmission link is used for communication between a cell governed by the base station and a core network and comprises an NG transmission link and a dual-connection ENDC transmission link; when at least one of the NG transmission link and the ENDC transmission link is in an unconnected state, determining that the transmission link is abnormal, and changing the type of the cell according to the current connection state; after changing the type of the cell, the activation state of the cell is re-determined.
Because in the above scheme, the current connection state of the transmission link is periodically detected; when at least one of the NG transmission link and the ENDC transmission link is detected to be in an unconnected state, determining that the transmission link is abnormal, and changing the type of the cell according to the current connection state; after the type of the cell is changed, the activation state of the cell is determined again; the transmission link is used for communication between a cell governed by a base station and a core network, and comprises an NG transmission link and a dual-connection ENDC transmission link. Therefore, after the transmission link of the cell is abnormal, the type of the cell can be changed, so that the cell can adopt the cell activation strategy corresponding to the changed type of the cell to re-determine the activation state of the cell, the cell can work normally, and the technical effect of improving the network coverage when the transmission link is abnormal is achieved.
In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
Referring to fig. 1, an embodiment of the present invention provides a method for activating a composite cell under a transmission link anomaly, which is applied to setting a base station in a composite networking, where a non-independent networking NSA and an independent networking SA share a cell in the composite networking, and a processing procedure of the method is as follows:
step 101: periodically detecting the current connection state of the transmission link; and the transmission link is used for the communication between the cell governed by the base station and the core network, and comprises an NG transmission link and a dual-connection ENDC transmission link.
The base station may detect the current connection status of the transmission link of the base station, e.g. every 10 seconds, since the transmission link of the base station comprises an NG transmission link and a dual-connectivity endec transmission link, i.e. the NG transmission link and the dual-connectivity endec transmission link.
The time interval of the detection period is not limited to 10 seconds, and may be freely set as needed in practical applications, and is not limited herein.
Because there are multiple NG transmission links and dual-connection ENDC transmission links, all NG transmission links are in an unconnected state during detection, the NG transmission links are determined to be in an unconnected state, otherwise, the NG transmission links are in a connected state; similarly, when all the ENDC transmission links are in an unconnected state during detection, the ENDC transmission links are determined to be in the unconnected state, otherwise, the ENDC transmission links are in a connected state.
For example, in the current period, 10 endec transmission links are detected to be in the connected state, 3 NG transmission links are detected to be in the connected state, and both the endec transmission links and the NG transmission links can be considered to be in the connected state.
For another example, in the next period, 1 piece of the endec transmission link is detected to be in a connected state, 0 piece of the NG transmission link is detected to be in a connected state, and the endec transmission link can be considered to be in a connected state, and the NG transmission link is considered to be in an unconnected state.
After detecting the current connection status of the transmission link of the base station, step 102 can be executed.
Step 102: and when at least one of the NG transmission link and the ENDC transmission link is in an unconnected state, determining that the transmission link is abnormal, and changing the type of the cell according to the current connection state.
The types of cells can be divided into composite cells and non-composite cells, the composite cells communicate with the core network through NG transmission links and ENDC transmission links, and the composite cells allow user terminals to access the cells through NSA and SA; the non-composite cells communicate with the core network via NG transmission links or endec transmission links, which allow the user terminals to access the cells via NSA or SA.
Under normal conditions, a transmission link of a base station arranged in the composite networking allows a user terminal to be accessed by NSA and SA in the same cell controlled by the base station. And when the type of the cell is the composite cell, the activation/deactivation of the cell is bound with the NG transmission link. Namely when at least one NG transmission link is in a connected state, the cell is in an activated state; when all NG transmission links are in an unconnected state, the cell is in a deactivated state (i.e. cell activation is not allowed).
Therefore, when at least one of the NG transmission link and the ENDC transmission link is in an unconnected state, the transmission link of the base station is determined to be abnormal, at the moment, the type of the cell is changed according to the current connection state, so that the cell can adopt a cell activation strategy with the type of a non-composite cell to re-determine the activation state of the cell, the cell can work normally, and the technical effect of improving the network coverage when the transmission link is abnormal is realized.
The type of the cell is changed according to the current connection state of the transmission link of the base station, and the method can be realized by adopting the following modes:
when only one connected transmission link exists in the transmission links, the type of the cell is changed to a non-composite cell.
The type of cell is kept as a composite cell when there is no connected transmission link in the transmission link.
For example, only 30 of the transmission links of the base station are connected, while all NG transmission links are unconnected; or only 2 NG transmission links in the transmission links of the base station are in a connected state, and all ENDC transmission links are in an unconnected state, and the type of the cell is changed into a non-composite cell.
And if at least one NG transmission link is in a connected state and all ENDC transmission links are in an unconnected state currently, changing the type of the cell into an SA cell.
For example, only 2 NG transmission links in the transmission links of the base station are in a connected state, and all the endec transmission links are in an unconnected state, it is determined that the transmission links of the base station are abnormal, at this time, the type of the cell needs to be changed from the composite cell to the SA cell, and the cell activation policy under the SA cell is used to re-determine the activation state of the cell.
If at least one ENDC transmission link is in a connected state and all NG transmission links are in an unconnected state, changing the type of the cell into an NSA cell; wherein the non-composite cell comprises an NSA cell.
For example, only 1 of the transmission links of the base station is in a connected state, and all NG transmission links are in an unconnected state, it is determined that the transmission link of the base station is abnormal, at this time, the type of the cell needs to be changed from the composite cell to the NSA cell, and the cell activation policy under the NSA cell is used to re-determine the activation state of the cell.
After the type of the cell is changed to the NSA cell, indication information for prohibiting the user terminal from accessing the cell in an SA manner may be broadcast. The indication information may be CELL BAR ACCESS, and of course, with the progress of technology and the establishment of new standards, the indication information may also be other information, which is not limited herein.
In one possible implementation, after the type of the cell is changed to the non-composite cell, in the next period, after detecting that at least one NG transmission link and at least one endec transmission link are both in the connected state, the type of the cell is restored to the composite cell.
For example, if the current cell is an NSA cell, and in the next detection period, 1 endec transmission link and 1 NG transmission link are detected to be in a connected state, the cell type is restored to the composite cell.
For another example, if the current cell type is an SA cell, and in the next detection period, it is detected that 1 endec transmission link and 20 NG transmission links are in a connected state, the cell type is restored to the composite cell.
After the transmission link of the base station is abnormal, the type of the cell is changed in the above manner, and step 103 can be executed.
Step 103: after changing the type of the cell, the activation state of the cell is re-determined.
The activation state of the cell is re-determined in the following ways:
in the first mode, when the type of the cell is a non-composite cell, the cell is in an active state.
For example, in the current cycle, after the type of the cell is changed to the NSA cell, the cell is determined to be in the activated state again according to the activation policy of the NSA cell.
For another example, after the type of the cell is changed to the SA cell in the current period, the cell is determined to be in the activated state again according to the activation policy of the SA cell.
And secondly, when the type of the cell is a composite cell and both the NG transmission link and the ENDC transmission link are in a connected state, the cell is in an activated state.
For example, in the previous cycle, the type of the cell is the NSA cell, and the cell is in the active state. And in the current period, after the type of the cell is recovered to the composite cell, re-determining the cell to be in an activated state according to the activation strategy of the composite cell.
For another example, in the previous cycle, the type of the cell is an SA cell, and the cell is in an active state, and in the next cycle, after the type of the cell is restored to the composite cell, the cell is determined to be in the active state again according to the activation policy of the composite cell.
And thirdly, when the type of the cell is the composite cell and the NG transmission link and the ENDC transmission link are both in an unconnected state, the cell is in a deactivated state.
For example, in the current period, both the NG transmission link and the endec transmission link are in an unconnected state, the type of the cell is maintained as the composite cell, and the cell is determined to be deactivated (i.e., unavailable) again according to the activation policy of the composite cell.
In the next period, if 1 NG transmission link and 1 endec transmission link are in the connected state, the type of the cell continues to be kept as the composite cell, and the cell is determined to be active (i.e. available) again according to the activation strategy of the composite cell.
Or, in the next period, if 1 NG transmission link and 0 endec transmission link are in the connected state, the type of the cell is changed to the SA cell, and the cell is determined to be activated (i.e. available) again according to the activation strategy of the SA cell.
Or, in the next period, if there are 0 NG transmission links and 1 endec transmission links in the connected state, the type of the cell is changed to the NSA cell, and the cell is determined to be active (i.e. available) again according to the activation policy of the NSA cell.
Based on the same inventive concept, an embodiment of the present invention provides a base station, where the base station is disposed in a composite networking, and a specific implementation manner of a method for activating a composite cell when a transmission link of the base station is abnormal may refer to the description in the method embodiment, and repeated details are not repeated, referring to fig. 2, where the base station includes:
