| 20100103935 | USING A CACHE OF OUTGOING PACKET IDENTIFIERS TO RECOVER FROM A PROTOCOL ERROR IN GTP-U - A process of using a cache of outgoing packet identifiers to recover from a protocol error includes assigning a receive identifier associated with a user entity to a traffic stream at a receive node. The receive identifier is sent to a transmit node. The transmit node is instructed to associate the receive identifier with a receive plurality of data packets of the traffic stream. The transmit identifier associated with the user entity is assigned to the traffic stream at the transmit node. The transmit node identifier, the receive node identifier, and the address of the receive node are stored in a transmit cache at the transmit node for each of the receive plurality of data packets. The receive plurality of data packets is sent from the transmit node to the receive node. An error message is received at the transmit node from the receive node, indicating that the receive identifier was not recognized. The transmit cache is searched for the transmit node identifier using the receive node identifier and the address of the receive node. The user entity associated with the transmit node identifier is identified, and the user entity is removed. | 04-29-2010 |
| 20080198992 | Method for Setting Up a Multimedia Connection In Case Of Cascade Connection Transfer - The invention concerns a method for setting up a multimedia connection via a packet-switching computer network between at least one first calling subscriber (A-Tln) and at least one first called subscriber (B-Tln), the called subscriber terminal (B-Tln) triggering a cascade call transfer to other subscriber terminals (C-Tln, D-Tln). The invention is characterized in that the multimedia connection of the calling subscriber (A-Tln) to the terminal of the first called subscriber (B-Tln) is first set up via a network element (PR) of the computer network. Then, the terminal of the first called subscriber (B-Tln) transmits to the network element (PR) the connection transfer to another terminal (C-Tln, D-Tln) and the data associated with said other subscriber terminal (C-Tln, D-Tln). The network element (PR) then retransmits, while maintaining the multimedia connection to the calling subscriber (A-Tln), the setting up of the connection to said other subscriber terminal (C-Tln, D-Tln). The invention thus ensures in simple manner that a specific network element (PR) continues, notwithstanding the cascade call transfer, to participate in the setting up of the multimedia connection, thereby enabling the multimedia connection to be taxed, a legal interception to be performed and traffic measurements to be made. | 08-21-2008 |
