Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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. 2. An application server apparatus provided in an IP Multimedia Subsystem (IMS), the application server apparatus comprising: a reception unit configured to receive a terminating signal from a call session control server apparatus in the IMS, the terminating signal directed to a mobile station and including call-type information indicating whether the terminating signal is for voice communication or Audio Video (AV) communication; and a determination unit configured to determine 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.
