Network selection and channel resource configuration method in hybrid wireless network

Abstract

The invention relates to a network selection and channel resource configuration method in a hybrid wireless network, which comprises the following steps: a base station to which each network belongs counts channel quantity and conditions per se, and broadcasts the channel quantity and the conditions to a mobile user in the base station; the mobile user selects a proper base station for accessing according to the estimation per se, and each base station counts access conditions and broadcasts user load conditions; the process is repeated until reaching a balance state, subsequently, inside of each base station is subjected to channel resource allocation; the base station broadcasts channel quantity information, each user returns self selected and accessed channel number; the base station counts channel selection states and broadcasts channel load conditions; and the process is repeated until reaching the balance state, and finally resource allocation in the base stations and network selection of the users are realized. The method disclosed by the invention is suitable for a 4G hybrid wireless network environment with a plurality of frequency spectrum owners, is dispersedly executed and has low complexity; and signaling overhead is saved, information interaction does not need among the channel owners, and information interaction does not need among the mobile users.

Description

technical field [0001] The invention relates to a method in the field of communication network technology, in particular to a method for user network selection and channel resource configuration in a hybrid radio network. Background technique [0002] A typical feature of the 4th generation (referred to as 4G) mobile communication network is the user's hybrid wireless network access capability. Mobile terminals can access various existing networks, such as Global Interoperable Microwave Access Network (referred to as WiMAX), Third Generation Partnership Project Long Term Evolution (referred to as LTE), Wireless Fidelity (referred to as WiFi), etc. . In order to enable mobile users to achieve wireless access with the required quality of service (referred to as QoS) in a mixed network environment, it is necessary to design a joint access mechanism including network selection and spectrum resource allocation. [0003] At present, the network selection problem and the resource...
