Using non-IMS connections in IMS sessions
Systems and methods can be implemented for IP multimedia subsystem (IMS) resource reservation. A first electronic device can transmit, through an IP network, a non-Session Initiation Protocol (SIP) message to an application server in an IMS network, where the non-IMS SIP message includes a request to initiate an IMS communication session through the IMS network with a second electronic device. A SIP message can also be transmitted through the IMS network to the application server that initiates a SIP INVITE session between the first electronic device and the application server, where the SIP INVITE session is routed through the IMS network. The first electronic device can then, receive a SIP response message that identifies a resource reservation for the IMS communication session from the application server.
1. A method, comprising:
receiving, at a first network node, a non-“Session Initiation Protocol (SIP)” authentication message, wherein the non-“SIP” authentication message is an Hypertext Transfer Protocol (HTTP) message;
receiving, at a second network node, a SIP message; and
associating, at the second network node, the SIP message with the non-“SIP” authentication message.
2. The method of claim 1 , wherein the first network node is the second network node.
3. The method of claim 1 , further comprising: after receiving the non-“SIP” authentication message, sending, by the first network node, a response that includes an identifier.
4. The method of claim 3 , wherein the identifier is included in the SIP message.
5. The method of claim 3 , wherein the associating is performed using the identifier.
6. The method of claim 1 , wherein the first network node and the second network node are different network nodes.
7. A communication network, comprising:
a first network node comprising:
a first receiver configured to receive a non-“Session Initiation Protocol (SIP)” authentication message, wherein the non-“SIP” authentication message is an Hypertext Transfer Protocol (HTTP) message; and
a second network node comprising:
a second receiver configured to receive a SIP message;
at least one hardware processor; and
a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the at least one hardware processor to perform operations comprising:
associating, at the second network node, the SIP message with the non-“SIP” authentication message.
8. The communication network of claim 7 , wherein the first network node is the second network node.
9. The communication network of claim 7 , wherein the first network node comprises a first transmitter, the first transmitter configured to: after the first receiver receiving the non-“SIP” authentication message, send a response that includes an identifier.
10. The communication network of claim 9 , wherein the identifier is included in the SIP message.
11. The communication network of claim 9 , wherein the associating is performed using the identifier.
12. The communication network of claim 9 , wherein the first network node and the second network node are different network nodes.
13. A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising:
receiving, at a second network node, a Session Initiation Protocol (SIP) message, wherein the non-“SIP” authentication message is an Hypertext Transfer Protocol (HTTP) message; and
associating, at the second network node, the SIP message with a non-“SIP” authentication message, wherein the non-“SIP” authentication message is received at a first network node.
14. The non-transitory computer-readable medium of claim 13 , wherein the first network node is the second network node.
15. The non-transitory computer-readable medium of claim 13 , wherein the first network node sends a response that includes an identifier after receiving the non-“SIP” authentication message.
16. The non-transitory computer-readable medium of claim 15 , wherein the identifier is included in the SIP message.
17. The non-transitory computer-readable medium of claim 15 , wherein the associating is performed using the identifier.
