Embodiment Construction

[0050] The present invention will be further described below with reference to the drawings and embodiments.

[0051] figure 1 As a system diagram of a heterogeneous wireless network, the network used in the present invention is the most common universal mobile communication system UMTS and wireless local area network WLAN. The network system includes two UMTS and four WLANs. The base stations and wireless access points of the network have been marked in the figure. They are BS1, BS2, AP1, AP2, AP3, and AP4. For the convenience of algorithmic representation, The six corresponding networks are marked as U1, U2, U3, U4, U5, U6. User terminals are randomly distributed in the entire network. In the figure, representative terminals are marked as UE1, UE2, UE3, UE4, UE5, and UE6. UE1 is in the overlapping coverage area of ​​networks U1 and U3; UE2 is in the overlapping coverage area of ​​U1, U2, U4, U5; UE3 is in the overlapping coverage area of ​​U1, U2, U5; UE4 is in the overlappin...

Abstract

The invention relates to a load balancing method based on forced switching in a heterogeneous wireless network system. The method comprises a) determining whether the load is greater than the threshold; b) determining the network set waiting for load increasing because the difference value of load is greater than a preset threshold value and an overlapping coverage area exists in the network waiting for load decreasing and in the heterogeneous wireless network; c) utilizing a user selection strategy for comprehensively considering the business rate, the fairness, the QoS profit and the network wireless resource utilization rate to select a target switching user; d) switching the target terminal, determining the network waiting for load increasing through a network selection algorithm based on a utility function and fuzzy logic, and switching the target; and e) determining whether the load is balanced. The load balancing method can automatically search out a suitable network waiting for load increasing and switch the target user when an overload network exists, and the user is switched to the network waiting for load increasing to realize load decreasing of the overload network, so that well running of each wireless network can be guaranteed and satisfying service can be always supplied to the user.

Description

Technical field [0001] The present invention relates to a load balancing method based on forced switching in a heterogeneous wireless network system, and more specifically, to a method that can effectively improve the overall utilization and utilization of network resources when the load is unbalanced in a heterogeneous network. A load balancing method based on forced handover for the user's quality of service. Background technique [0002] As people's requirements for wireless network communications continue to increase, a single network cannot meet user needs. Therefore, various wireless access network technologies emerge in endlessly, and the performance and applicable scenarios of different access technologies are different. The next-generation wireless network will be a converged heterogeneous network system where multiple wireless networks cover each other and coexist and complement each other. In order to obtain satisfactory services, users can seamlessly switch between v...
