Abstract
The present disclosure relates to data transmission methods, network devices. One example data transmission method includes: a first network node sends a first indication information to a second network node, the first indication information includes information about an uplink data volume of a buffer of a terminal device, or the first indication information indicates a relationship between an uplink data volume of a buffer of a terminal device and a predefined data volume threshold.

A method, comprising:
- receiving, by a first network device, a first report from a terminal device, wherein the first report indicates an uplink data volume of a buffer of the terminal device, and wherein the first network device is a distributed unit (DU) of a base station;
- and
- based on the uplink data volume of the buffer of the terminal device being greater than or equal to a predefined data volume threshold preconfigured by a second network device, sending, by the first network device, first indication information to the second network device, wherein the second network device is a central unit (CU) of the base station, and wherein the first indication information indicates a relationship between the uplink data volume of the buffer of the terminal device and the predefined data volume threshold preconfigured by the second network device.
A method, comprising:
- receiving, by a second network device, a first indication information sent by a first network device, wherein the first network device is a distributed unit (DU) of a base station and the second network device is a central unit (CU) of the base station, and wherein the first indication information indicates an uplink data volume of a buffer of a terminal device being greater than or equal to a predefined data volume threshold preconfigured by the second network device;
- and
- determining, by the second network device according to the first indication information, whether to perform state switching for the terminal device.
A first network device, comprising:
- at least one processor;
- and
- one or more memories including computer instructions that, when executed by the at least one processor, cause the first network device to perform operations comprising:
- receiving a first report from a terminal device, wherein the first report indicates an uplink data volume of a buffer of the terminal device;
- and
- based on the uplink data volume of the buffer of the terminal device being greater than or equal to a predefined data volume threshold preconfigured by a second network device, sending first indication information to the second network device, wherein the first network device is a distributed unit (DU) of a base station and the second network device is a central unit (CU) of the base station, and wherein the first indication information indicates a relationship between the uplink data volume of the buffer of the terminal device and the predefined data volume threshold preconfigured by the second network device.
