Abstract
To increase the number of services and applications in the telecommunication networks a new

service architecture has been proposed and specified. The consortia that initiated the new

service architecture is called Parlay. Since then, there has been a continued development and

3GPP the standardization group for 3G networks, is now cooperating with Parlay. 3GPP and

Parlay are together specifying the Parlay/OSA standard.

However, the aim with the new service architecture is to make the art of service

development so easy that any software developer should be a potential application developer

for telecommunication networks. It is foreseen to be a dramatic increase of new services,... (More)
To increase the number of services and applications in the telecommunication networks a new

3GPP the standardization group for 3G networks, is now cooperating with Parlay. 3GPP and

Parlay are together specifying the Parlay/OSA standard.

However, the aim with the new service architecture is to make the art of service

development so easy that any software developer should be a potential application developer

for telecommunication networks. It is foreseen to be a dramatic increase of new services, but

it has been shown that it is still complex to create new applications. Parlay X is a standard

which is an extension of Parlay/OSA, initiated to allow access to the telecommunication

network capabilities via web services. The Parlay X architectures include an Application

Server (AS), which translates the web service calls to Parlay/OSA commands. A typical AS is

a distributed environment sensitive to overload.

In this paper we propose and investigate an overload control mechanisms for an AS. The

methods have been implemented in a real AS to evaluate the performance. Parlay X is a

contract driven architecture, where different service providers have different constraints about

minimum number of service calls served per second and maximal delays of different services.

The methods and algorithms are designed to serve different service providers with different

contract parameters. (Less)
