Abstract
A proxy maintains registration in an IP Multimedia Subsystem (IMS) network for a user equipment while the user equipment is disconnected from the system. The user equipment connects to the proxy and establishes a proxy session with the proxy. The proxy opens a proxy session for the user equipment, establishes a registration within said IMS network for IMS services on behalf of the user equipment; and maintains the registration for the user equipment for the duration of the proxy session. While the proxy session is ongoing, the user equipment can disconnect from the IP proxy.
