Abstract
A method of delivering information from a Notifying node of a SIP/IMS network to a Watcher Client, via an intermediate Watcher Proxy. A connection is established between the Watcher Proxy and the Watcher Client, using a SIP session, wherein the established connection is used for forwarding a request for a SIP subscription to the Watcher Proxy as an embedded SIP subscribe message. Once a backend SIP subscription has been setup between the Watcher Proxy and the Notifying node, SIP notify messages delivered from the Notifying node will be forwarded from the Watcher Proxy to the Watcher Client via the established connection, thereby separating SIP subscribe traffic from SIP control traffic.
