SBC-localized handoff

摘要

Systems and methods are provided to facilitate the performance of a Session Border Controller (SBC)-localized handoff. As part of the SBC-localized handoff, a communication device may transmit packets within a data call to an SBC via a first IP address. Subsequently, the communication device may be assigned a second IP address. The communication device may then transmit further packets to the SBC via the second IP address. In response, the SBC may route all traffic within the data call direct to the communication device via the second IP address, regardless of whether the traffic indicates that the traffic should be delivered to the first IP address.

主权项

1. A method comprising:
associating, at a packet network interface, a first communication device, a particular port of a Session Border Controller (SBC, and a first IP address via which the first communication device is accessible; maintaining, by the packet network interface, a communications session between the first communication device and a second communication device; and during the maintained communications session:
receiving, at the particular port of the packet network interface, a first packet from the first communication device, the first packet including first content that is to be delivered to the second communication device, and the first packet indicating that the first communication device is accessible via a second IP address;subsequent to receiving the first packet, receiving, at the SBC from the second communication device, a second packet indicating the first IP address and including second content that is to be delivered to the first communication device; androuting, by the packet network interface, the content of the second packet to the first communication device by using the second IP address.
