Abstract:
According to a method and an apparatus in embodiments, in a redirection scenario, a target network device receives, from a terminal device, a first measurement result obtained in a source cell, and configures carrier aggregation CA and/or dual connectivity DC for the terminal device based on the first measurement result. In this way, a network side obtains a measurement result in advance, which reduces a latency between configuring, by a network side device, a measurement configuration for a terminal device after redirection and receiving a measurement result from the terminal device, so that the network side can configure proper CA and/or MR-DC for the terminal device earlier.
