In heterogeneous wireless networks, data transmission performance can be enhanced through the multi-access utilization of multi-mode terminals, it is carried out by the simultaneous employment of multiple parallel links over terminal's multiple radio access technologies. Promoting the multi-mode terminal's transmission performance while ensuring its energy efficiency is focused in this paper, we design a multiaccess transmission model and formulate the transmission delay minimization problem under the total data transmission rate demand and total transmission power constraint. An optimal traffic allocation algorithm using a modified particle swarm method is conducted to dynamically allocate traffic arrival rate for terminal's each radio access technology. Compared with the traditional algorithm, simulation results show that the proposed algorithm is efficient, and can significantly reduce the transmission delay while guaranteeing the total transmission power constraint.
