Communication method, secondary network node and terminal

A communication method, comprising:

• receiving, by a terminal device, first information sent by a secondary network node, wherein the first information is used for updating a configuration of a cell served by the secondary network node;
• and
• communicating, by the terminal device, with the secondary network node according to the first information,
• wherein the first information comprises IDs of all updated cells served by the secondary network node or an ID of an added cell or released cell served by the secondary network node, and
• wherein the measurement report comprises signal quality of a signal transmitted between the cell served by the secondary network node and the terminal device, and the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal device comprises Reference Signal Receiving Power (RSRP) or reference signal receiving quality (RSRQ).

A secondary network node, comprising a processor and a communication interface,

• wherein the processor is used for receiving a measurement report from a terminal device,
• wherein the communication interface is used for sending first information to the terminal device, wherein the first information is used for updating a configuration of a cell served by the secondary network node,
• wherein the first information comprises IDs of all updated cells served by the secondary network node or an ID of an added cell or released cell served by the secondary network node, and
• wherein the measurement report comprises signal quality of a signal transmitted between the cell served by the secondary network node and the terminal device, and the signal quality of a signal transmitted between the cell served by the secondary network node and the terminal device comprises Reference Signal Receiving Power (RSRP) or reference signal receiving quality (RSRQ).
