MSC LOGIC FOR SIP INVITE WITH IMRN |
| 摘要 |
A method of receiving, by a mobile switching center (MSC), a first call associated with an IP multimedia subsystem (IMS) network. The method determines whether an origination request return result (ORREQ rr) message, associated with the first received call, was previously received by the MSC. Based on the determination that the ORREQ rr was previously received, the method generates a session initiation protocol (SIP) invite message and sends the SIP invite message from the MSC. |
