Cell obtaining method, and terminal

A data processing method, wherein the method is applicable to the Narrowband Internet of Things, and comprises:

• sending, by a target base station, a first indication message to a core network device, wherein the first indication message is used to indicate that a terminal device completes a cell change or a cell reselection, wherein the target base station is a base station which the terminal device is connected after completing the cell change or the cell reselection;
• and
• receiving, by the target base station, the downlink data from the core network device.

A data processing apparatus, wherein the apparatus is applicable to the Narrowband Internet of Things, and comprises:

• a receiver, configured to receive a first indication message, wherein the first indication message is used to indicate that a terminal device completes a cell change or a cell reselection;
• and
• a transmitter, configured to send downlink data to a target base station, wherein the target base station is a base station which the terminal device is connected after completing the cell change or the cell reselection.

A non-transitory computer readable medium storing program codes for use by a core network device for data processing, wherein the program codes comprise instructions for:

• receiving a first indication message, wherein the first indication message is used to indicate that a terminal device completes a cell change or a cell reselection;
• and
• sending downlink data to a target base station, wherein the target base station is a base station to which the terminal device is connected after completing the cell change or the cell reselection.
