VIRTUAL ADMISSION CONTROL INFORMATION DISPLAY IN USER EQUIPMENT

by Cristovao Correia Da Silva

Abstract

This solution aims to provide prior information to the user on how its demand for networks resources are likely to be met, according to service.

Introduction

This paper describes how to allow the user to know beforehand the likelihood of obtaining any of the network services available to him. 3G networks are characterised by making available a wide range of services to each user however, these services will place very different demands on the network. A voice call will use much less network resources than a 384 LCD link, and so whilst it is likely that a user 800m from its serving cell will be able to make and receive voice calls it is unlikely that he will be able to establish a 384 LCD link. It would be very useful if the user knew beforehand what would be the result of attempting to establish each kind of link through what we shall denote as Virtual Admission Control, VAC. This consists in using the knowledge of relevant network and UE parameters to prejudge the admission control decision at the RNC if a request for such service was placed. The VAC result for each relevant service will then be communicated via the UE graphic display, allowing the user to make intelligent decisions in what concerns the request for network services.

Problem(s) To Be Solved

In current 2G networks the user is given an indication of network coverage, which gauges how likely he is to be able to make and receive calls. However, this simple indicator is clearly insufficient in the multi-service 3G environment, where the UE will be involved (sometimes simultaneously) in many different services, not just voice, with totally different network/air-interface requirements. Since the admission control decisions concerning these services are likely to be very different, there is a need for a specific indicator for each type of service.

Another 3G development is the ability of achieving the same result by using different services. Whilst, this is done automatically for packet-switch services where the Radio-Link controller assigns network resources to each user in order to optimise the overall performance, in what concerns LCD services that decision might still left to the user. In many cases the more sophisticated user will want to exercise this discretion because it is impossible for any generic admission control strategy to predict the expectations of all users. Obviously, to make these choices the user needs information on the availability of resources and maybe even pricing.

Proposed Solution to the Problem(s)

In order to make an intelligent decision about which services to request each user should be able to constantly monitor the likelihood of obtaining the various services available to him from the network. This can be achieved by displaying, on the user graphical inter...
