Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0027] Such as figure 1 As shown: the application server on the network side can access different core networks at the same time, and the different core networks and access networks can be interconnected and interoperable. The environmental information database is responsible for collecting and maintaining the status information of each core network and access network. A variety of network terminal devices can independently access different networks.

[0028] The network selection server includes a network environment information database and a network selection algorithm function module. The environmental information database is responsible for collecting and maintaining the status information of each core network and access network. The parameters involved in this example are network parameters, which mainly include network type and attributes, available bandw...

Abstract

The invention discloses a network link selecting method distinguishing an upstream data stream from a downstream data stream, and belongs to the technical field of wireless communications. The network link selecting method includes that a network selecting server obtains various medium streams of the upstream and downstream data streams according to business requirements of users, and matches a device required by business with the best network link according to network environment parameters and quality of service (QoS) information of the various medium streams. By means of the network link selecting method, the business requirements are divided into a plurality of medium streams by aid of differences of transmission rates of the upstream and downstream data stream links, uploading of the various medium streams is finished by means of the upstream or downstream data stream link with the maximum rate, and therefore selecting efficiency of a converged network is improved.

Description

technical field [0001] The invention discloses a network link selection method for distinguishing uplink and downlink data flows, and belongs to the technical field of wireless communication. Background technique [0002] The next-generation converged network architecture system is the coexistence, overlapping coverage and intercommunication of wireless networks including 2G (GSM), 3G (UMTS), LTE, WLAN, WiMax, etc., and wired networks including xDSL, broadcasting networks, etc. Terminal collaboration is to use single-mode or multi-mode terminal equipment for different networks, so that it can provide business continuity and synergy between the whole business or different parts under the environment of network convergence. [0003] The traditional network selection method is to select a network with the best quality as the access network of the device according to the quality of different networks that the user equipment can access. This method is aimed at the current situat...
