Heterogeneous network switching method for user service awareness and mobile terminal

Abstract

Embodiments of the invention disclose a heterogeneous network switching method for user service awareness and a mobile terminal, which can be used for solving a problem of seamless switching between a WiFi network and a WiMAX network in the field of heterogeneous networks. The embodiments of the invention aim at a WiMAX-WiFi heterogeneous network based on an IEEE 802.21 MIH framework, provide a method for adaptive switching of the user service awareness and allow as many terminal user connections as possible in the premise of guaranteeing the network load balancing, so that the network capacity, the resource utilization rate and the network cooperation efficiency are increased as high as possible, and meanwhile, information interaction between two networks is realized. The method has the advantage that the load rate of the network is improved in the premise of guaranteeing the user QoS / QoE through an access control mechanism and a load balancing scheduler.

Description

technical field [0001] The invention relates to the field of mobile terminal heterogeneous network switching, in particular to a user service-aware heterogeneous network switching method and a mobile terminal. Background technique [0002] A heterogeneous network is a network in which multiple access technologies coexist, and the wireless networks not only compete with each other, but more importantly, achieve the purpose of cooperative work. However, the main challenges faced by the current heterogeneous network handover include: the explosive growth of mobile data traffic leads to the continuous increase of network load; the unbalanced business and traffic load between hotspot areas, and the low utilization of network resources; the evolution of different types of networks makes The network structure is becoming more and more complex, and the efficiency of network collaboration is not good. [0003] In order to cope with unreliable switching of heterogeneous networks, loa...

However, the main challenges faced by the current heterogeneous network handover include: the explosive growth of mobile data traffic leads to the continuous increase of network load; the unbalanced business and traffic load between hotspot areas, and the low utilization of network resources; the evolution of different types of networks makes The network structure is becoming more and more complex, and the efficiency of network collaboration is not good

[0003] In order to deal with the load imbalance caused by the unreliable handover of heterogeneous networks, the utilization rate of resources will be reduced, so that the quality of experience (QoE) of users will not meet expectations.

Most of the existing handover methods are considered from the perspective of users or from the perspective of the network, and there are load imbalances or failure to accommodate more user access; although there are two aspects considered, the handover delay and handover signaling overhead are complicated. of low network utilization

[0004] Therefore, it is a technical problem to be solved by those skilled in the art to provide a method that can effectively solve the low network utilization rate caused by handover delay and handover signaling overhead in heterogeneous networks
