specific Embodiment approach 1

[0059] Specific implementation mode 1. Combination figure 1 Illustrate this specific embodiment, the wireless heterogeneous network mobile user position prediction method based on support vector machine, it is realized by the following steps:

[0060] Step 1. Build a heterogeneous network topology

[0061] In a hexagonal 3G sub-network, five non-overlapping WLAN sub-networks are set up.

[0062] Among them: the center of the 3G cell is located at coordinates (0, 0), and the radius is 1000m. Among the five WLAN cells, one center is located at coordinates (0, 0), and the coordinates of the centers of the other four WLAN cells are (-200, 0) , (0, 200), (200, 0), (0, -200), the WLAN cell radius r is 75m. topology such as figure 1 shown. Users move freely in the heterogeneous network, and S→D in the figure represents the possible trajectory of the user.

[0063] Step 2. Define the prediction network model

[0064] As mentioned above, for several key technologies of heterogene...

Abstract

The invention discloses a position prediction method of mobile users in a wireless heterogeneous network based on a support vector machine, and relates to the field of wireless heterogeneous networks. The method meets requirements of position prediction of the mobile users in the wireless heterogeneous network. The invention provides the position prediction method of the mobile users in a heterogeneous network environment based on the support vector machine (SVM). The position prediction method achieves the position prediction of the mobile users in the heterogeneous network environment. The invention provides the position prediction method capable of being adjusted adaptively according to different positions of the users based on a target area concept. Different position prediction methods are applied according to the different areas of the users, so that the prediction precision can be ensured, the overall complexity of the method can be reduced to a certain extent, the prediction expense is reduced, and resources are saved. The method is applicable to the position prediction of the mobile users in the wireless heterogeneous network.

Description

technical field [0001] The invention relates to the field of wireless heterogeneous networks, in particular to a method for predicting the position of a mobile user in a wireless heterogeneous network. Background technique [0002] The future wireless heterogeneous network has a complex network structure, a wide variety of services, and different users have different requirements for services. Therefore, various key technologies of wireless heterogeneous networks, such as access control technology, handover technology, user mobility management and network resource allocation, will face more difficult challenges than single wireless networks. The mobile user location prediction mechanism can well support the key technologies in the wireless heterogeneous network and improve its performance, and it is also an important part of the handover technology and mobility management technology. [0003] Specifically, if the user's movement path can be predicted more accurately, then o...
