The monitoring task information includes at least a configured monitoring object and a monitoring time period. Correspondingly, after the monitoring entity receives the monitoring task information sent by the 0AM system, the monitoring entity acquires the mobility parameter in the monitoring time period. Can Optionally, in the embodiment of the present invention, the mobility parameter may be optimized by a mobility optimization algorithm. The mobility optimization algorithm can be different for different network elements or network management systems.

In a further refinement of the basis of the embodiment shown in Fig. 1, an embodiment of the present invention provides a method for obtaining mobility information. Referring to Figure 2, the method includes:

Step 201: Obtain a mobility parameter of the monitored object during the monitoring period.

Optionally, the monitoring object is a neighboring cell relationship of a cell or a cell under the network element, and the start time and the ending time of the monitoring time period may be configured in the 0AM system in advance.

Alternatively, the mobility parameters can be processed by a mobility optimization algorithm. The entity running the mobility optimization algorithm first acquires the mobility parameter used by the neighboring cell relationship of the cell under the network element or the cell under the network element, and then uses the mobility optimization algorithm to operate the cell under the network element within the controlled range or The mobility parameter used by the neighbor relationship of the cell under the network element is optimized, and the value of the optimized mobility parameter is output. The monitoring entity obtains the value of the optimized mobility parameter of the entity output running the mobility optimization algorithm. Among them, the operator can define a controlled range for each mobility parameter in advance. Mobility parameters can include TTT (T ime To Tr i gger , delayed trigger time), Parameters such as Hyst and/or CIO (Cell Individual Offset). The mobility algorithm may include MRO (Mobility Robustness Optimization) or MLB (Mobility Load Balancing).

The entity running the mobility optimization algorithm optimizes the mobility parameters used by the neighboring cell relationship of the cell under the network element or the cell under the network element in real time during the monitoring period. Therefore, in this embodiment, the monitoring entity obtains the value of the optimized mobility parameter, and saves the value of the obtained mobility parameter, so that the mobility optimization algorithm can be learned in each mobility.

The neighboring cell relationship of a cell under the network element includes the cell and a neighboring cell of the cell, and the mobility parameter actually used by the neighboring cell relationship of the cell directly affects the handover between the cell and its neighboring cell.

For example, an entity that runs the mobility optimization algorithm during the monitoring period optimizes the mobility parameters actually used by the cell A under the network element, and assumes that the mobility parameters actually used by the cell A during the monitoring period include CI0, Hyst, and TTT. Correspondingly, the monitoring entity obtains the mobility parameter CI0 used by the cell A optimized in the monitoring period, including -3, -1, _1, -3, and -2, and the mobility of the optimized cell A.
