Method for transmitting data, network device and terminal device

A network device, comprising a processor, a transceiver and a memory storing instructions which when executed by the processor cause the transceiver to:

• receive a first measurement result and a second measurement result sent by a first network device, wherein the first measurement result is used for reflecting signal quality between a terminal device and the first network device and/or between the terminal device and the network device respectively, the first network device and the network device belong to a first communication system, the second measurement result is used for reflecting signal quality between the terminal device and a third network device and/or between the terminal device and a fourth network device respectively, the third network device and the fourth network device belong to a second communication system, and the first communication system and the second communication system are different communication systems;
• and
• send change information of the third network device and/or the fourth network device to the first network device.
