Abstract: In a data transmission method and apparatus, first user equipment (UE) sends a service request message to a first network side device. The first network side device determines, according to an identifier that is of a service and that is in the service request message, a service source that can provide the first UE with data of the requested service. After determining the service source, the first network side device sends configuration information to the first UE, where the configuration information is used to establish a data transmission path between the first UE and the service source. The first UE obtains the data of the requested service from the service source by using the data transmission path, instead of obtaining the data of the requested service from a server by using the first network side device.
