Abstract
Official abstract text for this publication.
Means and methodology for a SIP Invite receiving node to withdraw from the SIP session set-up loop by replying a redirect message to the SIP Invite sending node. The redirect message contains information for setting up alternative SIP session, said information being available in the SIP Invite receiving node. This information is needed by the SIP invite sending node for establishing an alternative SIP session as well as information needed by other nodes and applications further on in the SIP session set-up loop. The SIP Invite sending node is specially adapted to retrieve the information from the redirect message for establishing a new SIP session based on and containing the information from the redirect message. Several implementations are given for use in an IP Multimedia Subsystem of a telecommunication network.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method implemented in a Session Initiation Protocol (SIP) Invite message-sending (SIPIMS) node in a communication network, for removing a first SIP Invite message-receiving (SIPIMR) node from a SIP session setup loop to be established by the SIPIMS node, while passing on information available at said SIPIMR node to other nodes further on in a SIP loop that is to be established, comprising: receiving a SIP Redirect message from the first SIPIMR node r…
