Abstract
Embodiments of the present invention provide an Internet Protocol multimedia subsystem network, and a data transmission method and apparatus, which are used in the field of communications technologies. The data transmission method which is used in the IMS includes: performing tunnel encapsulation for an RTP packet to obtain a tunnel packet, where the tunnel packet includes a record unit, and a plurality of RTP packets are encapsulated in each record unit; and sending the tunnel packet to a peer end over a tunnel connected to the peer end. According to the embodiments of the present invention, the additional bandwidth caused by tunnel encapsulation is reduced, the bandwidth of a single packet is lowered, and the user experience and service access capabilities are improved.
