Title:
ＴＥＬ−ＵＲＩを用いた、ＩＭＳ呼のルーティング
Document Type and Number:
Japanese Patent JP5620965
Kind Code:
B2
Abstract:
The present invention proposes a specific handling of tel URIs in an IMS terminating network so as to enable routing of calls using telephone numbers (and not SIP URIs with embedded telephone numbers) as identifiers of the target users of those calls. Specifically, the present invention introduces a conversion module which is located within the IMS terminating network and is capable of converting SIP URIs with embedded telephone numbers into equivalent tel URIs which are then used by a terminating I-CSCF and S-CSCF to query the SLF and/or HSS so that they can route the calls to the target users.
