Embodiment Construction

[0062] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0063] As shown in Figure 1, in this embodiment, a complete closed-loop negative feedback control system is composed of a priority queue model, an adaptive fuzzy degradation control model, and an optimal allocation model of degradation range objects. The priority queue model provides The resource competition method of various types of services when system resources are in short supply, and the solution process of corresponding QoS parameters (handover call drop probability and new call blocking probability), the obtained switching call drop probability of each service ...

Abstract

A permission control method for calling of various service type based on adaptive control, which pertains to wireless network technology. The invention provides differentiating method of various service type based on QoS requirements of different service type in wireless network system; establishes model of queue with priority, proposes resource combating method of different service type when system resource is scarce, and provides general solving procedure of call dropping probability when service switching and blocking probability of new call by analysis of Markov birth and death process; establishes adaptive fuzzy degrade control model, proposes degrade control method of the current call when system resource is scarce, realizes dynamic balance of user QoS and system resource utility; finally, establishes optimal allocation model of degrade amplitude objects by non-linear programming algorithm. Three models proposed by the invention constitutes a close-loop control system together, which is excellent in completeness and robustness, and easy to implement.

Description

technical field [0001] The invention relates to a control method in the technical field of mobile communication, in particular to a multi-service type call admission control method based on adaptive control. Background technique [0002] One of the main goals of the fourth generation wireless network is to provide every mobile user with multimedia mobile services everywhere and all the time. Therefore, how to provide reliable services for multimedia services with different QoS (Quality of Service) requirements under the environment of diversified wireless access technologies (such as 3G cellular, IEEE802.11 WLAN, Bluetooth) has become the fourth generation wireless One of the most critical issues in network research. In order to provide reliable services for different types of services with different QoS requirements in a heterogeneous wireless network system, it is necessary to establish an effective call admission control method. [0003] Call admission control mainly so...
