Method and system to automatically park a voice call for data transfer
A system and method to automatically park a voice call on a mobile electronic device so that the device can receive data, comprising a switch for establishing a voice call at the at least one caller device, a database for storing at least one call processing rule, and an enterprise data server for receiving a data message, comparing contents of the data message with at least one rule in the database, and in the event that the contents match the rule then parking the call, switching the mobile electronic device to a data mode of operation, downloading the data message to the device and un-parking the call.
1. A system, comprising:
at least one mobile electronic device having a voice mode and a data mode of operation;
a switch for establishing a voice call at said at least one mobile electronic device;
a database for storing at least one call processing rule;
an enterprise data server receiving data intended for said mobile electronic device, accessing said database and comparing contents of the data with said at least one rule; and in the event that the contents match said at least one rule then notifying said switch to park the call, switching the device to a data mode of operation and downloading the data to the device while the switch has parked the call, and notifying said switch to un-park the call, wherein upon receipt of notification from the enterprise data server to park the call, a user agent within the switch sends a Session Initiation Protocol (SIP) REFER message to a park server agent within the switch which in response sends an INVITE message to a remote party to replace said call between the mobile electronic device and remote party with a Real-time Transport Protocol (RTP) stream between the park server and remote party.
2. The system according to claim 1 , wherein said switch is a SIP-capable Private Branch Exchange (PBX).
3. The system according to claim 1 , wherein said mobile electronic device is a 2 G mobile electronic device.
4. The system according to claim 1 , wherein the Real-time Transport Protocol (RTP) stream includes an automated voice announcement indicating that the call has been place on hold pending delivery of an important data message.
5. The system according to claim 1 , wherein upon receipt of notification from the enterprise data server to un-park the call, the user agent issues an INVITE to the remote party for replacing the session between the remote party and park server with a two-way Real-time Transport Protocol (RTP) stream between the mobile electronic device and remote party.
6. The system according to claim 1 , wherein said at least one rule includes an importance threshold.
7. The system according to claim 1 , wherein said park server agent includes functionality for inserting a voice announcement in said Real-time Transport Protocol (RTP) stream for announcing that the call has been parked pending delivery of an important data message.
8. The system according to claim 7 , wherein said announcement is made to at least one of the mobile electronic device and remote party.
