Abstract

The invention provides a method for data transmission, a diverging point device, a user terminal and a system thereof. The method comprises the following steps of: allocating downlink data to be sent to a user terminal on the basis of a preset strategy to a first air interface and a second air interface, wherein the user terminal is connected to a core network by a first access network through a first air interface, and is connected to the core network by a second access network through the second air interface; sending downlink data allocated to the first air interface to the user terminal through the first air interface; and sending downlink data allocated to the second air interface to the user terminal through the second air interface. Based on the technical scheme, data transmitted to the first air interface and the second air interface is flexibly allocated, and communication states of the first air interface and the second air interface are linked for being uniformly managed, therefore, energy saving effect of the user terminal is favorably improved, use efficiency of network resources is increased, and overlarge transmission load caused to the single air interface is relieved.

Description

technical field [0001] The present invention relates to the communication field, and more particularly, to a method for data transmission in the communication field, a distribution point device, a user terminal and a system thereof. Background technique [0002] With the emergence of smart phones, various new data services emerge as the times require. Under this background, the mobile data volume of cellular networks, especially 3G (Third Generation, third generation) networks, shows explosive growth. In order to reduce the load of the 3G network, various offloading technologies including WiFi (Wireless Fidelity, Wireless Fidelity) offloading and micro-cell offloading have emerged. Among them, WiFi offloading is the most valued solution by operators, and has already begun to spread among operators. Scope of deployment. [0003] From the perspective of WLAN (Wireless Local Area Network, Wireless Local Area Network) and mobile network interworking methods such as UMTS (Univer...
