Problems solved by technology

Therefore, choosing similar utility functions for different services will have an impact on the performance of network resource allocation algorithms
At present, the multi-service-based wireless network resource allocation method mainly has the following shortcomings: the utility-based resource allocation considers the utility change characteristics of various services in the network, and uses the utility function of different services as the objective function to establish a utility maximization mathematical model. model, but the optimization model does not distinguish between business and user priorities, so this model is not suitable for scenarios with priority distinction

Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Assume that the heterogeneous wireless network environment is covered by two types of wireless networks, WLAN and UMTS, and each wireless network has two access points, namely, n∈{1,2}, s∈{S 1 ,S 2}, where n=1 means RAT1 It is a WLAN network, n=2 means RAT 2 For UMTS networks, S 1 Indicates the set of access points in the WLAN network, S 1 ={1,2},S 2 Denotes the set of access points in the UMTS network, S 2 ={1,2}, the types of user terminals are all multi-mode single-standby terminals. In this wireless network environment, all terminals have the opportunity to access any network to obtain bandwidth resources.

[0044] S1. The terminal user generates a service request, specifically: the terminal user sends a request to the wireless access point under its own wireless network according to its own service requirements, and reports the terminal user ...

Abstract

The invention belongs to the technical field of wireless network resource allocation, in particular to a heterogeneous wireless network resource allocation applicable to multiple services. In the method of the present invention, when multiple mobile terminal services come at the same time, accessing a suitable wireless network for the terminal can not only meet the business needs with priority distinction, but also reasonably allocate network bandwidth resources to meet the maximum All kinds of business requests maximize the total utility of the wireless network. In this process, using the utility function in the form of Sigmoid can conveniently model multiple types of business in a unified way, which is conducive to reducing the complexity of the resource allocation algorithm in the execution process. .

Description

technical field [0001] The invention belongs to the technical field of wireless network resource allocation, in particular to a heterogeneous wireless network resource allocation applicable to multiple services. Background technique [0002] Heterogeneous wireless networks refer to network systems with multiple wireless access technologies. Common access networks include 3G / 4G cellular mobile communication networks, IEEE802 series wireless local area networks and wireless metropolitan area networks. Different access networks cover There are differences and complementarities in scope, transmission rate, bandwidth, price, etc.; at the same time, the QoS requirements of various services in wireless networks are different, such as session services are sensitive to network delay requirements; The service type is a typical "request-response service", and the tolerable network delay is between the session type and the flow type service; the background type service includes file tra...
