<p>Provided are a system and method for supporting the same number using SRVCC. The system for supporting the same number using SRVCC of the present invention comprises: an IMS network , a CS network a first terminal device and a second terminal device , wherein the first terminal device is used for establishing a session between the IMS network and the second terminal device using a subscriber number , and is also used for establishing a session between the CS network ,and the second terminal device using the subscriber number when being switched from the IMS network to the CS network while it is a calling party. The method can support an SRVCC system to establish sessions among different networks using the same number during domain switching , improve the operating efficiency of the SRVCC system , and facilitate the use by users.</p> |
