Abstract
Disclosed in the present invention are a data transmission method and a network device. The method comprises: sending first information to a second network device, the first information being used to assist the second network device to determine whether to perform early sending of called data targeting a terminal.
Claims13
A data transmission method, performed by a first network device, the method comprising:
- during establishing a Packet Data Network, PDN, connection, determining whether an early transmission of downlink data is to be used for the PDN connection according to at least one of the following information:
- capability information of the terminal about support for an early transmission of called data,
- local configuration information, or
- service data information provided by external networks;
- and
- receiving, by the first network device, first indication information of whether to transmit first information to a second network device,
- wherein the first indication information includes a size of called data;
- determining, by the first network device and based on the received first indication information, to transmit the first information to the second network device;
- upon determining to transmit the first information, generating, by the first network device, the first information based on the size of called data by comparing the size of called data with a preset threshold,
- wherein the first information is configured to assist the second network device in configuring its early transmission of downlink data for a terminal, wherein the first network device is a mobility management entity, MME, or an access and mobility management function, AMF, and wherein the second network device is a radio access node, RAN;
- and
- transmitting the first information to the second network device,
- wherein the method further comprises:
- receiving a second message transmitted by the terminal, and determining, based on the second message, capability of the terminal about support or nonsupport for the early transmission of called data;
- and
- determining whether to transmit the early transmission of called data for the terminal according to service data information provided by an external network.

A first network device comprising:
- a processor;
- a memory for storing computer programs;
- and
- a transceiver,
- wherein the processor is configured to execute the computer programs stored in the memory to:
- during establishing a Packet Data Network, PDN, connection, determine whether an early transmission of downlink data is to be used for the PDN connection according to at least one of the following information:
- capability information of the terminal about support for an early transmission of called data,
- local configuration information, or
- service data information provided by external networks;
- and
- receive, by the first network device, first indication information of whether to transmit first information to a second network device,
- wherein the first indication information includes a size of called data;
- determine, by the first network device and based on the received first indication information, to transmit the first information to the second network device;
- upon determining to transmit the first information, generate, by the first network device, the first information based on the size of called data by comparing the size of called data with a preset threshold,
- wherein the first information is configured to assist the second network device in configuring its early transmission of downlink data for a terminal, wherein the first network device is a mobility management entity, MME, or an access and mobility management function, AMF, and wherein the second network device is a radio access node, RAN;
- and
- transmit the first information to the second network device via the transceiver,
- wherein the processor is further configured to execute the computer programs stored in the memory to receive, via the transceiver, a second message transmitted by the terminal, and determine, based on the second message, capability of the terminal about support or nonsupport for the early transmission of called data, and
- wherein the processor is further configured to determine whether to transmit the early transmission of called data for the terminal according to service data information provided by an external network.
