  • IMS call routing using tel-URIs
    Patent number: 9237088
    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.
