Data transmission method, terminal, and network side device

A data transmission method, wherein the method comprises:

• in a case that a sensing service request message is received from a consumer device, sending, by a first network element, a first sensing service control message to a radio access network (RAN) according to the sensing service request message, wherein the first sensing service control message comprises at least tunnel information of the first network element;
• wherein the first sensing service control message is used to instruct the RAN to establish a sensing service shared channel, wherein the sensing service shared channel corresponds to the tunnel information of the first network element, and the sensing service shared channel is used for transmitting at least one piece of sensing measurement data corresponding to a first sensing service;
• wherein the tunnel information of the first network element comprises tunnel endpoint identification information of the first network element and/or address information of the first network element;
• wherein the RAN transmits, based on the first sensing service control message, a second sensing service control message to a sensing signal measurement device associated with a first sensing task, wherein the second sensing service control message is used for establishing a data channel between the RAN and the sensing signal measurement device.

A data transmission method, wherein the method comprises:

• receiving, by a sensing signal measurement device, a third sensing service control message sent by a first network element, wherein the third sensing service control message is used for establishing a first sensing service, and the first network element transmits a first sensing service control message comprising at least tunnel information of the first network element to a radio access device (RAN), the tunnel information of the first network element comprising tunnel endpoint identification information of the first network element and/or address information of the first network element;
• performing, by the sensing signal measurement device, measurement on a sensing signal based on the third sensing service control message to obtain at least one piece of sensing measurement data, wherein the sensing signal corresponds to the first sensing service;
• and sending, by the sensing signal measurement device, the at least one piece of sensing measurement data to a radio access network (RAN);
• wherein the method further comprises:
• receiving, by the sensing signal measurement device, a second sensing service control message sent by the RAN, wherein the second sensing service control message is used for establishing a data channel between the RAN and the sensing signal measurement device.
