System and method for configuring and executing communication diversion with a globally routable user agent uniform resource identifier
View Patent ↗A method for diverting a Session Initiation Protocol (SIP) message is provided. The method includes receiving a SIP message comprising a Globally Routable User Agent Uniform Resource Identifier (GRUU). The method further includes evaluating a diversion rule including a condition comprising whether the first GRUU matches a second GRUU, wherein the second GRUU is contained in the condition.
1. A method for diverting Session Initiation Protocol (SIP) messages using rules, the method comprising:
receiving a SIP message including a first field, the first field comprising a first Globally Routable User Agent Uniform Resource Identifier (GRUU) identifying a node, wherein the first GRUU comprises a GR URI parameter and a GR parameter value;
evaluating a communication policy comprising a diversion rule, the diversion rule including a condition, the condition comprising matching the first GRUU to a second GRUU, wherein the second GRUU is contained in the condition and wherein the communication policy further comprises a target field set to a URI; and
in response to evaluating the diversion rule, diverting the SIP message when the first GRUU matches the second GRUU, the diverting comprising setting a second field of the SIP message to the URI of the target field.
2. The method of claim 1 , wherein the first GRUU further comprises a public user identity (PUID).
3. The method of claim 1 , wherein the first GRUU is a GRUU of at least one of:
a first node that originates the SIP message;
a second node to which the SIP message is targeted;
a third node to which the SIP message is diverted; or
an intermediate node to which the SIP message was targeted;
and wherein the second GRUU is a GRUU of at least one of:
a first node that originates the SIP message;
a second node to which the SIP message is targeted;
a third node to which the SIP message is diverted; or
an intermediate node to which the SIP message was targeted.
4. The method of claim 1 , wherein the first GRUU is located in at least one of:
a Contact header field in the SIP message;
a History-Info header field in the SIP message;
a P-Asserted-Identity header field in the SIP message;
a To header field in the SIP message; and
a From header field in the SIP message.
5. The method of claim 1 , wherein the SIP message is a SIP INVITE request.
6. The method of claim 1 , wherein the method is implemented through a modification of a Communication Diversion (CDIV) configuration.
7. A telecommunications network, comprising:
a component including a processor configured to execute instructions on a storage device in order to:
receive a Session Initiation Protocol (SIP) message including a first field, the first field comprising a first Globally Routable User Agent Uniform Resource Identifier (GRUU) identifying a node, wherein the first GRUU comprises a GR parameter and a GR parameter value;
evaluate a communication policy comprising a diversion rule, the diversion rule including a condition comprising whether the first GRUU matches a second GRUU, wherein the second GRUU is contained in the condition, and wherein the communication policy further comprises a target field set to a URI; and
in response to evaluating the diversion rule, diverting the SIP message when the first GRUU matches the second GRUU, the diverting comprising setting a second field of the SIP message to the URI of the target field.
8. The telecommunications network of claim 7 , wherein the first GRUU further comprises a public user identity (PUID).
9. The telecommunications network of claim 7 , wherein the first GRUU is at least one of:
a first node that originates the SIP message;
a second node to which the SIP message is targeted;
a third node to which the SIP message is diverted; or
an intermediate node to which the SIP message was targeted; wherein the first GRUU is located in at least one of:
a Contact header field in the SIP message;
a History-Info header field in the SIP message;
a P-Asserted-Identity header field in the SIP message;
a To header field in the SIP message; or
a From header field in the SIP message;
and wherein the second GRUU is a GRUU of at least one of:
a first node that originates the SIP message;
a second node to which the SIP message is targeted;
a third node to which the SIP message is diverted; or
an intermediate node to which the SIP message was targeted.
10. The telecommunications network of claim 8 , wherein the SIP message is a SIP INVITE request that is diverted through a modification of a Communication Diversion (CDIV) configuration.
