Abstract
The present invention provides a method and apparatus for data transmission in a communication network. In the present invention, additional frequency spectrum resources in an assistant wireless network are introduced by constructing emulation data channels for use by a user equipment in a cellular network, thereby expanding the resources in the cellular network and enhancing throughput of the cellular network. In addition, the original control channels between the base station and the user equipment in the cellular network are maintained, enabling the user equipment to have the quality of service QoS in the cellular network when using the assistant wireless network to transmit data, and sparing the user equipment from handover operations in establishing or releasing the emulation data channels, thereby complicated network control and management mechanisms used for the handover are not needed and thus the user experience is further enhanced. Moreover, it is relatively easy to be implemented and cost efficient.
