Heterogeneous fusion network-based traffic management method and system

Abstract

The present invention provides a heterogeneous fusion network-based traffic management method and system. The method comprises steps of A1, when a user terminal accesses a WiFi AP, acquiring current network state information and generating a measurement report; A2, calculating, based on the measurement report and information of each WiFi AP, remaining sub-carrier resource of each WiFi, and acquiring all available WiFi APs of the user terminal; A3, allocating, based on all available WiFi APs and QoS demands, a to-be-transmitted data package sent by a core network to an LTE network and a WiFi network to transmit; and A4, sending an RCC connection establishing signal to the user terminal and establishing a connection, and sending the to-be-transmitted data package to the user terminal through the LTE network and the WiFi network. An authorized frequency and an unauthorized frequency are fully used to meet the QoS demands of users, and the authorized frequency and the unauthorized frequency are managed in a unified manner.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a traffic management method based on a heterogeneous converged network. Background technique [0002] At present, the exponential growth of data traffic and diverse user demands have brought challenges to LTE networks, especially in hotspot areas. In order to improve system capacity, Small Cell (low-power nodes) and WiFi systems are generally deployed in hotspot areas, gradually forming a new heterogeneous network with different characteristics, working in two different frequency bands, authorized and unlicensed . [0003] On the one hand, the WiFi system has the advantages of low deployment cost and high peak rate, but its coverage is limited and it is only suitable for low-speed mobile users. With the dense deployment of WiFi, the occurrence of a large number of conflicts will also affect user performance. The WiFi system does not support seamless han...

Problems solved by technology

With the dense deployment of WiFi, the occurrence of a large number of conflicts will also affect user performance

The WiFi system does not support seamless handover and cannot guarantee communication connectivity during the handover process; on the other hand, the 3GPP cellular system has the characteristics of wide coverage and high spectrum efficiency

However, with the large increase of Small Cells, its shortcomings of scarce spectrum resources and serious interference are quickly realized
