Abstract

Official abstract text for this publication.

Methods, systems and communication nodes for protecting Session Initiation Protocol (SIP) message payloads are described. Different protection techniques can be used to protect SIP payloads depending upon, for example, whether a recipient client application resides in a user equipment or an application server and/or whether a recipient client application resides in a same SIP/IP domain as the target SIP application server which is sending the SIP payloads.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for protecting a Session Initiation Protocol (SIP) message payload transmitted between a target SIP application server toward a client application residing in one of a user equipment (UE) or in another SIP application server comprising: determining an appropriate protection scheme for protecting said SIP message payload based on whether said target SIP application server is associated with said client application's domain or with another domai…
