S101: Acquire a configuration identifier of the UE.

Optionally, after the UE accesses the network, the second network side device queries the configuration identifier corresponding to the UE from the pre-stored correspondence between the UE and the configuration identifier, and the second network side device sends the configuration identifier of the UE to the first network. Side equipment.

In this embodiment, the configuration identifier refers to a User Profile Identifier (SPID).

S102: Determine, according to a preset correspondence between the preset configuration identifier and the carrier aggregation policy, a carrier aggregation policy corresponding to the configuration identifier of the UE.

Here, the corresponding relationship between the preset configuration identifier and the carrier aggregation policy in the foregoing step is flexibly set by the operator according to actual requirements, and is sent by the second network side device to the first network side device.

When the first network-side device detects that the RB occupied by the current network is greater than 60% of the network bandwidth and is smaller than If the RB of the network is greater than 80% of the network bandwidth and less than or equal to 90% of the network bandwidth, the network running status is poor.

After the current running status of the network is obtained, S202 is performed. In a specific implementation process, the S202 may include: determining, according to a preset correspondence between the network operating status and the carrier aggregation policy, a carrier aggregation policy corresponding to the current running status as an update policy.
