The following quote was obtained by the news editors from the background information supplied by the inventors: "In the context of mobile network and VOIP over data connection to receive incoming VOIP call the end point should inform server regarding its current location.
"Known methods which based on popular SIP standards require that the end point should inform server regarding its current location using mechanism of SIP registration. This registration should be permanently maintained which requires VOIP application on device to be permanently running. In addition to keep pinhole open at firewall, VOIP client should use additional mechanisms (keep alive, registration refreshes, persistent connection, etc). All that result in using resources of mobile device and shorter battery life. In addition, many mobile OS don't allow applications to run on background or may unload application in arbitrary manner.
"As a solution many VOIP application leverage 'registration on demand' approach when application is either awaken or activated by push notification sent by the server. Once awaken/activated application sends registration requests and server route call to the device based on this registration. This approach causes significant delays for accepting incoming calls because it requires propagating a registration request from the device to the server and than a call request from the server to the device.
"There therefore exists a need for a method and system that provides an effective way of accepting incoming VOIP calls without maintaining permanent registration which save the battery life and can be also time efficient.
"There therefore exists a need for service providers to enable a method and system that can establish a call to their customers by answering incoming VOIP call through VOIP pick up call without maintaining of permanent SIP registration and therefore reduce the power consumption on the phone and reduce the delay of answering the call."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "It is therefore an object of the invention to provide a method and a system for receiving incoming VOIP call without maintaining of permanent SIP registration.
"The invention therefore provides a method for receiving incoming VOIP call without maintaining of permanent SIP registration comprising: receiving initial incoming VOIP call through the call control application server (CCAS); keeping this initial call request by CCAS and notifying user's mobile phone equipped with mobile application by sending notification to this application; retrieving of parameters of pickup call from notification message or from configuration on the phone by mobile application; making a VOIP pickup call from this mobile phone with appropriate parameters (Replaces header can be used, but other proprietary mechanisms can be used as well); holding initial incoming call until CCAS receives an incoming VOIP pickup call from the user device and after that completing the call.
"The invention further provides a system for receiving incoming VOIP call without maintaining of permanent SIP registration, comprising: a mobile phone equipped with application client programmed to: monitor notification about incoming VOIP calls from a call control server (CCAS); retrieve parameters of pickup call from notification message or from configuration on the phone by mobile application; make a VOIP pickup call from this mobile phone with appropriate parameters (Replaces header can be used, but other proprietary mechanisms can be used as well); and a call control application server (CCAS), comprising a service programmed to: receive initial incoming VOIP call; keep this initial call request and send notification about the call request to the application on user's mobile phone; wait for incoming VOIP pickup call from the subscriber mobile phone; correlate this VOIP pickup call request with initial VOIP incoming call based on information provided in VOIP pickup call and complete the connection between them.
"The invention further provides a mobile handset application client, comprising: program instructions for receiving notification from the server about incoming VOIP call through different notification mechanisms; retrieving parameters of VOIP pickup call from this notification message or from local configuration prior to initiating of VOIP pickup call; making a VOIP pickup call from this mobile phone with appropriate parameters (Replaces header can be used, but other proprietary mechanisms can be used as well).
"The invention yet further provides a call control application server, comprising: a service application that is receiving VOIP incoming call to subscriber; instead of sending call to the device sending notification to the device by using push notification, SMS or another mechanism; keeping (parking) this initial received incoming call request while waiting for incoming VOIP call pick up from the subscriber phone; correlates this VOIP pickup call request with initial VOIP incoming call based on information provided in VOIP pickup call; completes the call setup request to connect the subscriber to the initial VOIP incoming call.
BRIEF DESCRIPTION OF THE DRAWINGS
