Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] figure 1 It is a schematic diagram of the network layer mobility management function structure applied by the mobility management method of the present invention.

[0040] figure 1 The network layer mobility management function structure shown is divided into three layers, the bottom layer is composed of wide area mobile communication network (WCDMA, CDMA2000, etc.), wireless local area network (WLAN), time division synchronous code division multiple access (TD-SCDMA) ), large area synchronous code division multiple access (LAS-CDMA) and other wireless access networks; the middle layer is the network layer supported by protocols such as mobile IP, IPv4 / v6 and cellular IP; the top layer is the It is a functional unit composed of location management, fast switching, paging, security, quality of service control, and authentication. Such as figure 1 As shown in ...

Abstract

The network layer includes at least two levels of management domain. The method includes following step: (a) measuring switching intensity of current management domain and adjacent management domain; (b) based on measured result of switching intensity, adjusting management ranges of current management domain and adjacent management domain forms structure of management domain in new levels with minimum switching spending. The invention measures switching intensity in real time, evaluates network spending, and based on evaluating result, subordination of management domain in network is changed dynamically. Thus, network hierarchy can be self-organized based on practical situation so as to reduce signaling spending in network, as well as raise service quality of network.

Description

technical field [0001] The invention relates to a management method of a mobile communication network, in particular to a mobility management method of hierarchical network layers in the mobile Internet. Background technique [0002] Mobile communication and the Internet are two hot spots in the development of the information industry today, and the integration of the two has produced a new growth point, that is, the mobile Internet. It adopts the Internet Protocol IP to realize interconnection among heterogeneous networks, which is conducive to the development of future networks towards all-IP networks, and provides users with higher communication rates and richer services. Mobility management is one of the key technologies of the mobile communication system. The so-called mobility management is used to deal with the problems involved in the movement of users in the mobile communication network. It is the core issue of the mobile communication network. With the transformat...
