Use of packet data duplication to manage access network connections

摘要

As a communication device receives packet data via a first access network, the communication detects that packet data arriving via a second access network is duplicative of the packet data that the communication device is receiving via the first access network. In response to detecting such duplication, the communication device discontinues being served by the first access network and continues with communication via the second access network.

主权项

1. A method comprising:
a communication device being served by a first access network and receiving packet data from a remote endpoint via the first access network, wherein a first bearer extends from a packet gateway via the first access network to the communication device, and wherein the packet data flows from the remote endpoint to the packet gateway and via the first bearer to the communication device; while receiving the packet data from the remote endpoint via the first access network, the communication device being served by a second access network and beginning to receive a duplicate of the packet data from the remote endpoint via the second access network, wherein a second bearer extends from the packet gateway via the second access network to the communication device, and wherein the duplicate of the packet data flows from the packet gateway via the second bearer to the communication device; detecting, by the communication device, that the packet data that the communication device is receiving from the remote endpoint via the second access network is duplicative of the packet data that the communication device is receiving from the remote endpoint via the first access network; and responsive to the detecting, the communication device discontinuing being served by the first access network, wherein discontinuing being served by the first access network comprises transmitting a detach request to the first access network.
