This paper discusses methodologies for effcient Session Initiation Protocol (SIP) message routing on the application layer in the IP Multimedia Subsystem (IMS) of 3rd Generation Partnership Project (3GPP) UMTS networks. The contributions are twofold: Firstly, it introduces a generic multidimensional optimisation metric that can be used in conjunction with existing routing protocols. The metric’s sensitivity depends on the network operating conditions. Secondly, it outlines the need for SIP message routing and introduces concepts that allow eﬀective message routing on the SIP layer. It uses the deﬁned optimisation metric which is, in this case, sensitive to delay, reliability and availability of resources. The introduced methodologies are also applicable for routing problems in generic overlay networks.
