Abstract: An individual IMS terminal acquires address and place information of a service discovery server present in the local IP network from an AP. Next, the individual IMS terminal may query the service discovery server to find out an SIP URL address of a sharing IMS terminal. When the individual IMS terminal finds out the sharing IMS terminal, its own IMS subscription information is transmitted to the sharing IMS terminal. The sharing IMS terminal is dynamically registered in the IMS depending on the received IMS subscription information. When the process ends, the sharing IMS terminal has the same IMS subscription information as the individual IMS terminal, such that the session mobility control provided by the IMS may be applied as it is.
