Abstract: Embodiments of the present invention provide a link control node and method, and a system. An MPTCP sublink is identified; and from the MPTCP sublink, a first MPTCP sublink on which link control needs to be performed is determined, and an adjustment manner applicable to the first MPTCP sublink is determined. By adding centralized management and control measures on MPTCP connections, a data transmission process on each MPTCP sublink can be performed on an expected communication link, which adapts to running requirements of a system. Therefore, radio resources can be appropriately allocated, and system performance can be improved.

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.
