Methods, systems, and computer program products for triggering SIP nodes to include SS7 routing information in response messages including information requested by SS7 nodes
First Claim
1. A method for triggering session initiation protocol (SIP) nodes to include signaling system number seven (SS7) routing information in response messages including information requested by SS7 nodes, the method comprising:
- (a) receiving, from an SS7 node, a first message having SS7 routing information, wherein the SS7 routing information includes message transfer part level 3 (MTP3) user adaptation layer (M3UA) network appearance information, network group code information, or an SS7 point code, wherein a network appearance parameter, together with a signaling point code, uniquely identifies an SS7 node;
(b) generating a corresponding SIP message that includes the SS7 routing information and a parameter instructing a receiving SIP node to include the SS7 routing information in a SIP response message; and
(c) forwarding the corresponding SIP message to a remote SIP node.

Abstract
Methods, systems, and computer program products are disclosed for triggering SIP nodes to include SS7 routing information in response messages including information requested by SS7 nodes. A message having SS7 routing information is received from a remote SS7 node. A corresponding SIP message is generated that includes the SS7 routing information and a parameter for triggering the SIP node to include the routing information in a response message. The corresponding SIP message is forwarded to a remote SIP node.

15. A system for triggering session initiation protocol (SIP) nodes to include SS7 routing information in response messages including information requested by signaling system number seven (SS7) nodes, the system comprising:
-
(g) an SS7 network interface for receiving, from an SS7 node, a first message having SS7 routing information, wherein the SS7 routing information includes message transfer part level 3 (MTP3) user adaptation layer (M3UA) network appearance information, network group code information, or an SS7 point code, wherein a network appearance parameter, together with a signaling point code, uniquely identifies an SS7 node; (h) a message processor for generating a corresponding SIP message that includes the SS7 routing information and a parameter for triggering a SIP node to include the routing information in a response message; and (i) an IP network interface for forwarding the corresponding SIP message to a remote SIP node. - View Dependent Claims (16, 17, 18, 19, 20, 21)
