A data communication method and apparatus are disclosed. The method includes: a first base station receiving address information of a Transport network layer (TNL) sent by a second base station; the first base station receiving uplink data sent by a terminal device, the uplink data corresponding to a quality of service (QOS) stream; when the uplink data needs to be borne by a default data radio bearer (DRB) of the first base station, and a general packet radio service tunneling protocol (GTP) channel corresponding to the QoS stream is established on the second base station, the first base station establishing a connection with the second base station according to the address information, to transmit the uplink data borne on the default DRB to the second base station, and then transmit the uplink data to a core network device through the GTP channel.

Data transmission method and apparatus

Disclosed by the present application are a location management function (LMF) selection method and terminal location service method and device, said method includes a mobility management function entity, in response to a location service request message from a gateway mobile location center (GMLC), choosing a first LMF to provide a location service to the terminal, sending a confirm location request message to the first LMF, the first LMF being a core network LMF or an LLMF associated with a first access node; the mobility management entity, in response to the location redirection message from the first access node or a second access node, sending a confirm location request message to a second LMF, the second LMF being selected for the terminal by the first access node or the mobility management function entity, the second LMF being a core network LMF or an LLMF associated with the second access node.
