Abstract
Instead of rejecting an incoming request at a node of a SIP domain, e.g. an IMS domain, when a user database query has failed, it is determined whether the DNS domain name of the request is registered as a shared domain or not. If it is found that the DNS domain name is registered as a shared domain, the DNS domain name is resolved into a globally routable URI, and the request is routed towards the terminating entity. If, however, the DNS domain name is not shared, the request is rejected. Such a mechanism enables operators to allow for a DNS domain name to be utilized by more than one SIP domain.
Claims20
A method in a node of a SIP domain for handling an incoming request for a SIP service at the SIP domain for which a user database query has failed, the method comprising the following steps:
- determining if a DNS domain name of said request is registered as a shared domain, by checking configuration data, said configuration data comprising all DNS domains managed by an operator of said SIP domain,
- resolving said DNS domain name into a globally routable URI, and
- one of routing said request towards a terminating entity if said DNS domain name is registered as a shared domain, and
- rejecting said request if said DNS domain is not registered as a shared domain.
A node of a SIP domain in a telecommunications network for handling an incoming request for a SIP service at the SIP domain for which a user database query has failed, the node comprising a microprocessor, a main memory coupled to the microprocessor and persistent storage, associated with the microprocessor, including instructions that, when executed by the microprocessor, cause the node to perform the following:
- initiating a domain checking procedure in response to said failed user database query, by checking configuration data, said configuration data comprising all DNS domains managed by an operator of said SIP domain, and
- said domain checking procedure comprising determining if the DNS domain of said request is registered as a shared domain or not,
- resolving said DNS domain name into a globally routable URI and routing said request towards the terminating entity if said DNS domain is registered as a shared domain, or rejecting said request if said DNS domain is not registered as a shared domain.
