Mobile communication method and application server apparatus |
摘要 |
A mobile communication method according to the present invention includes the steps of: when an S-CSCF in an IMS receives a terminating signal directed to a UE, sending the terminating signal from the S-CSCF to an SCC-AS in the IMS, the terminating signal including call-type information indicating whether the terminating signal is for voice communication or AV communication; sending an inquiry signal including the call-type information from the SCC-AS to an HSS; and determining, by the SCC-AS, a domain to which the terminating signal is to be transferred, based on the call-type information and a response signal received from the HSS as a response to the inquiry signal. |

1. A mobile communication method comprising the steps of:
when a call session control server apparatus in an IP Multimedia Subsystem (IMS) receives a terminating signal directed to a mobile station, sending the terminating signal from the call session control server apparatus to an application server apparatus in the IMS, the terminating signal including call-type information indicating whether the terminating signal is for voice communication or Audio Video (AV) communication; and determining, by the application server apparatus, that a domain to which the terminating signal is to be transferred is a radio access network supporting circuit switch, when the call-type information included in the terminating signal indicates that the terminating signal is for AV communication and the AV communication via the IMS cannot be provided. |
