TITLE{Effective resource management using reparameterisations}

by {P Randall, W Featherstone}

Abstract

{This method provides a mechanism to oversee algorithm performance and resource levels and to adjust parameters that impact these to maximise overall network performance.}

Introduction

{This paper deals with the self-management and optimisation of algorithms within a network element to efficiently serve mobile telephony users within the resource limitation of that network element.}

Problem(s) To Be Solved

{Due to advances in technologies, more and more complexity is being added into network elements to manage radio resources (or other resources) being used in mobile phone networks. This increased complexity leads to higher demands on the finite hardware resource (e.g. memory, available central processing unit (CPU) cycles) that may change depending on parameterisations of algorithms within the network element. Typically, only manual adjustment of these parameters is provided, such that the parameters have to be selected to suit a wide range of scenarios which can result in sub-optimal network performance and an inability to grant access to all users attempting to connect to the network.

An example of this area is the radio resource control (RRC) state switching algorithm(s) within the radio network controller (RNC) in a Universal Mobile Telecommunications System (UMTS) network. There exist different levels of RRC “connectedness”, specifically the following states: CELL_DCH, CELL_FACH, CELL_PCH, URA_PCH and idle [3GPP TS 25.331 V3.6.0 (2001-03): RRC Protocol Specification]. In each state, there are different tradeoffs to be made – for example to support a user in fully connected CELL_DCH state there is a higher processing overhead. This overhead is a result of having to support dedicated connection management, for example soft/softer handoff, power control, rate adaptation and link quality control. However in CELL_DCH state the user experience is far better as the user has access to a dedicated resource and therefore does not experience the delay overhead associated with the signalling procedures necessary to transition th...
