User application-oriented adaptive access network selection device and method

Abstract

The invention discloses an adaptive access network selection device and an adaptive access network selection method, which belong to the technical field of communication. Own macro and micro characteristics of a terminal are sensed, a service sensitivity variable is determined according to a user application status and preference analysis, network application priorities and quality of service (QoS) sensitivity priorities are sequenced based on information such as the characteristics of the terminal, application needs, network statuses and the like, adaptive modeling is performed on different networks according to historical data, the QoS characteristics of a user terminal accessing the networks are acquired, an access network is judged according to the guidance information of an intelligent information management module and the actual output of an intelligent network simulation module and inter-network switching is performed. By the device and the method, heterogeneous networks are accessed adaptively optimally and selectively to effectively realize the user transparency orientation of heterogeneous properties of the access network and the terminal universality orientation of application service characteristics.

Description

technical field [0001] The invention relates to a communication optimization technology in the heterogeneous network field, in particular to an adaptive management method for resource management and access network selection in the heterogeneous access network. Background technique [0002] The future communication network will be a heterogeneous converged network in which various access technologies coexist and cannot replace each other. Various network access technologies such as WiFi, WiMAX, UMTS, and even satellite networks and MANET (Mobile Ad Hoc Networks) and other wireless networks can realize IP-based voice, data and multimedia services. Seamlessly integrated heterogeneous networks, such as figure 1 shown. [0003] Different access networks have brought a lot of inconvenience to users and operators due to their technical differences and incompatibility. For example, it is difficult to maintain real-time smoothness of the application services being served between di...

Problems solved by technology

Its technical feature is that the optimization form is fixed and lacks flexibility; it is not suitable for the complex and variable current network environment. Facing the increasing complexity of the network environment and the comprehensive trend of business applications, there is still no good solution to the problem of network selection.
