Cooperation resource management method and system in heterogeneous wireless network

Abstract

The invention relates to the resource managing field of a radio network, especially a method and a system for cooperating with the resource management in an isomerism radio network. When the mobile terminal is updating-accessed to the network, the trigger comprises the resource request message with the network list; when the candidate resources are all in the managing range of the local radio resource managing unit, the local radio resource managing unit decides the target network; when the candidate resources are not in the managing range of the local radio resource managing unit, the local radio resource managing unit adds the local network state information to the resource request message, finally the terminal radio resource managing unit is accessed to the target network according to the deciding result. The invention has the combined accessing control and resource scheduling in the access network with different properties in the isomerism radio network achieving the maximization for the using rate for the isomerism radio network based on the service request.

Description

technical field [0001] The invention relates to the field of resource management of wireless networks, in particular to a collaborative resource management method and system in heterogeneous wireless networks. Background technique [0002] In the current wireless network research, it is generally believed that the future 4G communication network is essentially an environment where multiple heterogeneous wireless networks converge, and the concept of multi-radio access is considered to be the most likely existence of future wireless networks. form.

AI Technical Summary

Problems solved by technology

[0003] Traditional wireless resource management manages the resources within a single network without considering the available resources of other networks. Its goal is to provide service quality assurance for wireless user terminals in the network under the condition of limited bandwidth.

However, this isolated resource management method cannot effectively utilize the network capabilities of future multi-wireless access, and has the following disadvantages:

[0004] When a user generates a new service and needs to access the wireless network, because the user does not know the current network situation, some networks may be idle and no user accesses, while other networks are overloaded and new users are blocked, which cannot guarantee services with different characteristics quality of service

[0005] On the other hand, the users faced by heterogeneous wireless networks are mobile. When users move to the edge of a certain network, they need to switch to other available networks. Since users do not know which network can meet the business needs, they choose randomly The network may cause business interruption, and cannot guarantee smooth vertical handover, seamless mobility of users and continuity of business

[0006] To sum up, traditional wireless resource management is an internal function of a single network, which cannot meet the needs of heterogeneous network integration in the future, cannot coordinate resources between wireless networks, and cannot allocate optimal network resources in real time according to user service characteristics. The quality of service cannot be guaranteed, and the resource utilization of the network is low
