Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] In the existing network selection method, the network is mainly selected based on the signal strength, and the terminal preferentially stays on the network with strong signal. However, the network at this time may have reached a high load state and cannot provide high-quality services to users. Based on this, the embodiment of the present invention provides a multi-network-based data transmission method and device. The embodiment of the present invention takes the load conditions of each network as a reference basis, and combines access and switching load balancing to achieve Select the appropriate network for data transmission. The following will be described in detail through specific embod...

Abstract

The invention discloses a multi-network-based data transmission method and a multi-network-based data transmission device. The multi-network-based data transmission method comprises the following steps: when a terminal receives a data transmission request of a user, querying the load conditions of all networks in sequence according to the decreasing sequence of the transmission performances of all the networks by the terminal; when the load condition of a current network is queried to be smaller than a first load threshold, regarding the current network as an access network by the terminal; and establishing a connection between the access network and the terminal and carrying out data transmission through the access network. According to the invention, the problem that multi-mode terminals in relevant technologies cannot use a network with a superior transmission performance is solved, and the terminal can select an appropriate network according to the load conditions of the networks, so that the network access quality of the terminal is increased and the load balance among heterogeneous networks is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a multi-network-based data transmission method and device. Background technique [0002] In my country, the pattern of traditional operators is determined by the second generation (2G for short) network. After the formation of the third generation (3G for short) network, data services are developing rapidly. The future LTE era More so, the involvement of wireless local area network (Wireless Local Area Network, WLAN for short) capabilities will have a major impact on operators' low-cost offloading of data services. Therefore, China Mobile is currently facing the operational status of the integration of four networks, including Global system for Mobile Communication (GSM for short), Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, short for Coordinated development of four networks including TD-SCDMA), TD-SCDMA Long...
