Method and apparatus for call notification and delivery to a busy mobile station
First Claim
1. A method of call handling in a wireless communication network comprising:
- receiving an incoming voice call for a mobile station that is busy in a packet-switched data call;
sending an incoming call notification to the mobile station via signaling over an existing traffic channel allocated to the data call; and
reconfiguring the existing traffic channel to support the incoming voice call and delivering the incoming voice call to the mobile station via the reconfigured existing traffic channel.

Abstract
A call handling method and apparatus provide improved call handling in scenarios where concurrent voice and data service is not supported, or is not possible. A wireless communication network can be configured to provide real-time notifications of incoming voice calls to mobile stations that are busy in data calls, and can route those incoming voice call to voice mail, etc. The network can be configured to attempt call delivery of an incoming voice call to a mobile station busy in a data call with or without prompting the mobile station user, depending on the type of data service the mobile station is engaged in. According to exemplary embodiments, the traffic channel and other resources as desired are retained from the data call for use in supporting the voice call. Also, the mobile stations can be configured to support such notification, reconfiguration and channel retention processing.

14. A method of call handling in a mobile station for use in a wireless communication network, the method comprising:
-
carrying on a packet-switched data call over an existing traffic channel; and renegotiating the existing traffic channel for circuit-switched voice call use responsive to signaling from the network, said renegotiating including receiving a call notification from the network via signaling on the existing traffic channel indicating that an incoming circuit-switched voice call is pending for the mobile station, returning a notification response to the network via signaling on the existing traffic channel based on prompting a user of the mobile station as to whether receipt of the incoming circuit-switched voice call is desired, sending and receiving signaling as needed to and from the network via the existing traffic channel to reconfigure it for circuit-switched voice use, and receiving an alert message from the network via signaling on the existing traffic channel indicating that the incoming circuit-switched voice call is set up and returning a call connect order to the network via signaling on the existing traffic channel; and changing from carrying on the packet-switched data call to carrying on the circuit-switched voice call over the existing traffic channel.
