Using non-IMS connections in IMS sessions
View Patent ↗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, by one or more network nodes and from an electronic device, a non-“Session Initiation Protocol (SIP)” message through a non-SIP-based network;
authenticating, by the one or more network nodes, the electronic device based, at least in part, on authentication information in the received non-“SIP” message;
receiving, by the one or more network nodes, a SIP message through a SIP-based network; and
associating, by the one or more network nodes, the SIP message received through the SIP-based network with the non-“SIP” message received through the non-SIP based network.
2. The method as claimed in claim 1 , wherein the non-“SIP” message is one of a Representational State Transfer (REST) message, a transmission control protocol (TCP) message, P2P protocol message, a proprietary protocol message, or an HTTP message.
3. The method as claimed in claim 2 , wherein the authenticating is based on security provided by transport layer security (TLS) to secure a communications channel.
4. The method as claimed in claim 1 , wherein the authenticating is based on security provided by a transport protocol.
5. The method as claimed in claim 1 , further comprising initiating a SIP session with a second electronic device in response to a request to initiate the SIP session, wherein the request is associated with the non-“SIP” message.
6. The method of claim 1 , further comprising in response to receiving the non-“SIP” message, initiating a SIP dialog with the SIP-based network prior to receiving the SIP message from the electronic device.
7. The method as claimed in claim 1 , wherein the electronic device is one of a user equipment (UE), a server, a private branch exchange (PBX), and a gateway.
8. The method as claimed in claim 1 , wherein the SIP-based network is an IMS network.
9. An electronic device comprising a processor configured to:
send, to one or more network nodes, a non-“Session Initiation Protocol (SIP)” message through a non-SIP based network; and
send, to the one or more network nodes, a SIP message through a SIP-based network, wherein the SIP message includes information for correlation with the non-“SIP” message at the one or more network nodes.
10. The electronic device as claimed in claim 9 , wherein the non-“SIP” message is one of a Representational State Transfer (REST) message, a transmission control protocol (TCP) message, P2P protocol message, a proprietary protocol message, or an HTTP message.
11. The electronic device as claimed in claim 9 , wherein the processor is further configured to initiate a SIP session with a second electronic device in response to a request to initiate the SIP session, wherein the request is associated with the non-“SIP” message.
12. The electronic device as claimed in claim 9 is one of a user equipment (UE), a server, a private branch exchange (PBX), and a gateway.
13. The electronic device as claimed in claim 9 , wherein the SIP-based network is an IMS network.
14. A non-transitory computer-readable medium storing instructions that are executable by one or more data processing apparatus to perform operations comprising:
receiving, by one or more network nodes and from an electronic device, a non-“Session Initiation Protocol (SIP)” message through a non-SIP-based network;
authenticating, by the one or more network nodes, the electronic device based, at least in part, on authentication information in the received non-“SIP” message;
receiving, by the one or more network nodes, a SIP message through a SIP-based network; and
associating, by the one or more network nodes, the SIP message received through the SIP-based network with the non-“SIP” message received through the non-SIP based network.
15. The non-transitory computer-readable medium as claimed in claim 14 , wherein the non-“SIP” message is one of a Representational State Transfer (REST) message, a transmission control protocol (TCP) message, P2P protocol message, a proprietary protocol message, or an HTTP message.
16. The non-transitory computer-readable medium as claimed in claim 14 , wherein the authenticating is based on security provided by a transport protocol.
17. The non-transitory computer-readable medium as claimed in claim 16 , wherein the authenticating is based on security provided by transport layer security (TLS) to secure a communications channel.
18. The non-transitory computer-readable medium as claimed in claim 14 , wherein the operations further comprise initiating a SIP session with a second electronic device in response to a request to initiate the SIP session, wherein the request is associated with the non-“SIP” message.
19. The non-transitory computer-readable medium as claimed in claim 14 , wherein the operations further comprise in response to receiving the non-“SIP” message, initiating a SIP dialog with the SIP-based network prior to receiving the SIP message from the electronic device.
20. The non-transitory computer-readable medium as claimed in claim 14 , wherein the electronic device is one of a user equipment (UE), a server, a private branch exchange (PBX), and a gateway.
21. The non-transitory computer-readable medium as claimed in claim 14 , wherein the SIP-based network is an IMS network.
