Emergency packet data network communication system and call features
First Claim
1. A method of providing callback from a called party to an anonymous initiating user device after a dropped call in a packet data network communication system, the method comprising the steps of:
- initiating a call from the user device on an originating network;
detecting a missing identity of the user device;
assigning an interim identity to the user device;
routing the call with the associated interim identity to the called party;
disconnecting of the call, with the user device roaming to a new network;
attaching of the user device on the new network with PDP context activation;
providing the interim identity of the user device and an originating network identity to the new network; and
forwarding a callback of the called party from the originating network to the new network to the user device camped on the new network using the information from the providing step.

Abstract
A method and apparatus for providing callback from a called party to an anonymous initiating user device after a dropped call in a packet data network communication system includes a first step of initiating a call from the user device on an originating network. A next step includes detecting a missing identity of the user device. A next step includes assigning an interim identity to the user device. A next step includes routing the call with the associated interim identity to the called party. A next step includes disconnecting of the call, with the user device roaming to a new network. A next step includes attaching of the user device on the new network with PDP context activation. A next step includes providing the interim identity of the user device and an originating network identity to the new network. A next step includes forwarding a callback of the called party from the originating network to the new network to the user device camped on the new network using the information from the providing step.

8. A method of providing emergency callback from an emergency calling center to an anonymous initiating user device after a dropped call in a packet data network communication system, the method comprising the steps of:
-
initiating an emergency call from the user device having a missing identity on an originating network;
detecting a missing valid identity of the user device;
assigning an interim identity to the user device and associating the interim identity with an equipment identity of the user device;
routing the call with the associated interim identity to the emergency calling center;
disconnecting of the call, with the user device roaming to a new network;
attaching of the user device on the new network with PDP context activation, wherein a new interim identity is assigned;
providing the interim identity of the user device and an originating network identity to the new network and the new interim identity and new network identity back to the originating network; and
forwarding data packets of the emergency callback of the emergency calling center from the originating network to the new network to the user device camped thereon using the interim identities and network identities. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A communication system for facilitating callback from a called party to an anonymous caller, the communication system comprising:
-
a user device capable of anonymously accessing a packet data network in the absence of an identity;
a packet data network operable to provide communications between the user device and the called party, the packet data network operable to detect a missing identity of the user device, and to detect a disconnected call; and
an emergency packet data network, wherein upon notification from the packet data network that a user device has no identity, the emergency packet data network is operable to assign an interim identity to the user device and route the call with the associated interim identity and an identity of the packet data network to the called party, and wherein upon notification from the packet data network that an anonymous call has been disconnected, the emergency packet data network is operable to provide the interim identity of the user device and an originating packet data network identity to the any new network where the user device is attached with active PDP context and to forward any callback of the called party from the originating network to the new network to the user device attached thereon. - View Dependent Claims (16, 17, 18, 19, 20)
