Method and system for enhancing measurement capability of a terminal device

A network communication system, comprising:

• a network device;
• and
• a terminal device, configured to:
• camp on a first cell and a second cell using a carrier aggregation (CA) technology, wherein the first cell and the second cell are long term evolution (LTE) cells, and the first cell is a primary cell;
• send first information to the network device, wherein the first information indicates whether a measurement gap is required when the terminal device performs inter-frequency measurement;
• and
• report an event A2 of the second cell when the terminal device meets a preset first condition or when the network device meets a preset second condition, wherein the event A2 is specified in a protocol as indicating that a signal quality of a corresponding cell is less than a threshold, and the event A2 enables the network device to de-configure the second cell from being a carrier aggregation cell of the terminal device;
• and
• wherein the network device is configured to:
• send a second message to the terminal device based on the first information when it is determined that a measurement gap is required, wherein the second message indicates to measure a network parameter of a third cell, and the second message comprises measurement gap information;
• and
• send a third message to the terminal device when it is determined that no measurement gap is required, wherein the third message indicates to measure the network parameter of the third cell, and the third message comprises no-gap information.

A method, comprising:

• sending, by a terminal device, first information to a network device, wherein the first information indicates whether a measurement gap is required when the terminal device performs inter-frequency measurement;
• camping, by the terminal device, on a first cell and a second cell using a carrier aggregation (CA) technology, wherein the first cell and the second cell are long term evolution (LTE) cells, and the first cell is a primary cell;
• sending, by the network device, second information to the terminal device, wherein the second information indicates to measure a network parameter of a third cell, the third cell is a New Radio (NR) cell, and the second information comprises information of the measurement gap;
• suspending, by the terminal device, data receiving or sending in the second cell when the terminal device finds no third cell during the measurement gap;
• and
• measuring, by the terminal device, the network parameter of the third cell.
