Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a configuration update method according to the present invention is shown, which may specifically include the following steps:
in this embodiment of the present invention, the distribution unit may receive a Configuration Update request sent by the concentration unit, where the Configuration Update request may be used to trigger a Configuration Update procedure (Configuration Update).
in the embodiment of the present invention, the central unit side may encounter abnormal situations, such as a failure of cell configuration information due to the central unit starting from a self-detection task, a failure of cell configuration information due to a suspended process of the central unit, an abnormal processor, and an abnormal storage, and cause a failure of the cell configuration information, for example, an activation condition of a cell cannot be known or the cell configuration information is deleted. At this time, since the central unit is only responsible for activation and deactivation of the cells, the configuration information of the cells is abnormal on the central unit side, but the abnormal cells are maintained on the distribution unit side, so that the physical resources corresponding to the cells cannot be released.
Therefore, a cell information invalidation identifier may be added to the configuration update request, where the cell information invalidation identifier is used to indicate whether an abnormal condition occurs at the central unit side, so that the configuration information of the cell is invalidated. And if the configuration information of the cell at the side of the centralized unit is invalid, the cell invalid identifier is a valid cell information invalid identifier.
In a specific implementation, the value of the cell information invalidation identifier may be 0 or 1, tune or false, and the like, which is not limited in the present invention. For example, when the value of the cell information invalidation flag is 0, it indicates that the problem of invalidation of the configuration information of the cell does not occur on the concentrating unit side, and when the value of the cell information invalidation flag is 1, it indicates that the problem of invalidation of the configuration information of the cell occurs on the concentrating unit side, and at this time, it may be considered that the cell information invalidation flag is valid.
In a specific implementation, the value of the cell information invalidation identifier may further include cell information with an abnormal occurrence, which is used to indicate that the distribution unit needs to update the cell configuration information in a preset cell information list.
In this embodiment, the cell information list may include at least one cell configuration information, where the cell configuration information includes an identifier and a status of a cell.
In the embodiment of the present invention, when there is an effective outgoing information invalidation identifier in the configuration update request, it indicates that the configuration information of the cell at the central unit side is invalid.

in the embodiment of the present invention, when the distribution unit determines that a valid cell information invalidation identifier exists in the configuration update request sent by the concentration unit, the distribution unit may try to help the concentration unit to update the concentration unit information list, so that the currently invalidated cell is recovered to be normal. Thus, the distribution unit may obtain the target cell configuration information related to the concentration unit from a preset cell configuration list, and prepare to send to the concentration unit.
A substep 22 (not shown in the figure) of generating a configuration reset request using said target cell configuration information;
in this embodiment of the present invention, the distribution unit may send a configuration resetting request to the concentration unit, where the configuration resetting request may include the target cell configuration information, and is used for the concentration unit to update the concentration unit information list.

In the embodiment of the present invention, the central unit may set, according to an actual situation, all the cell information failure flags or a part of the cell information failure flags in the configuration update request to be in an effective state. For example, when the cell configuration information in the central unit is unable to know the activation condition or the cell configuration information is partially deleted, the cell information partial failure flag in the configuration update request may be set to be in an effective state, and the cell configuration information unable to know the activation condition may be further supplemented. When all the cell configuration information in the central unit is deleted, all the cell information invalidation identifiers may be set to be in an effective state.
In a preferred embodiment of the present invention, the configuration reset request comprises a first reset request and a second reset request;
