The embodiment of the invention provides an internet protocol, a multimedia subsystem network, a data transmission method and a device, which are used in the communication technology field. Among them, for the data transmission method comprises the following steps: IMS tunnel encapsulation of the RTP message, which includes message tunnel, tunnel message recording unit, each recording unit is encapsulated with multiple RTP message; message through to the tunnel and the tunnel end, between the end of the sending end, STG or IMS terminal. The embodiment of the invention reduces the additional bandwidth caused by tunnel encapsulation, thereby reducing the bandwidth of the single packet, the packet is larger because of the additional bandwidth, put forward higher requirements on the user access bandwidth, to a certain extent, reduce the use of user experience and service access ability.
