Abstract

A method of deleting an item from a user account in a SIP multimedia environment. When an item such as an instant message is to be deleted, a SIP REFER message is transmitted from a user device to delete the item from the user account, with the message including a unique identifier for the item. In response to the transmitted request, an SIP INVITE session is established between a virtual agent and a network-based deleted items location. After the SIP INVITE session is established, the item is transferred from the user account to the network-based deleted items location and is deleted from the user account.

Claims

1. A method of deleting an item from a user account in a session initiation protocol (SIP) multimedia environment, comprising the following computer-implemented steps:

receiving a request from a user device to delete the item from the user account, the request comprises a SIP REFER request including a unique identifier for the item to be deleted;

establishing a SIP session between a remote recycle bin and the user account; and

after establishing the SIP session, transferring the item from the user account to the remote recycle bin for automatic deletion without transfer of the item to a local recycle-bin.

2. The method of claim 1, wherein the SIP REFER request includes an address for the remote recycle bin in its Refer-to header.

4. The method of claim 1, further comprising, in response to receiving the request, transmitting an acknowledgment of the request to the user device.
