Abstract

A data transmission method and device are provided, the method comprising: sending a connection request including a small data indicator to a base station; and in response to receiving a connection establishment message from the base station including a configuration of a signaling radio bearer and a data radio bearer, Send a connection establishment complete message to the base station, so as to obtain the resource allocation result.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method and equipment. Background technique [0002] In order to reduce the signaling overhead caused by switching from idle (idle) mode to radio resource control connected (RRC CONNECTED) mode, the solutions currently adopted by the industry include: sending a small amount of data (hereinafter referred to as "small data") in the UE Passed when there is no non-intervention layer (NAS) signaling connection. Two options are described in TR23.887. Both options are based on the principle of providing the UE with information about the bearer endpoints of a Public Data Network (PDN) connection in a signaling gateway (eg S-GW). [0003] Tunneling is used in the above solutions, where the base station (e.g. eNB) can directly forward the small data to the S-GW without bearer establishment and without involving the Mobility Management Entity (MME). The eNB identifies specifi...
