Abstract:
Provided in the present application are a downlink data transmission method and device. The method comprises: a user plane apparatus receiving downlink data of a terminal; the user plane apparatus sending to an access network apparatus in a tracking area of the terminal, via a shared bearer, the downlink data; the access network apparatus receiving a context establishment request message sent by a control plane apparatus; the access network apparatus establishing, according to the context establishment request message, a radio bearer between the access network apparatus and the terminal; and the access network apparatus sending to the terminal the downlink data via the radio bearer. In this way, a transmission delay is reduced for downlink data, thus improving downlink data transmission efficiency.
