Reducing latency and packet loss related to handoffs of mobile video traffic

摘要

In one embodiment, a system including a memory capable of storing data and a processor is disclosed. The processor is configured for using the data such that the system can request from a source gateway subscription information related to a plurality of multicast video streams subscribed by the source gateway upon receiving a handoff request from a mobile device transitioning from a source region to a target region, wherein the handoff request contains information related to the source gateway. The processor is further configured for using the data such that the system can subscribe to at least a subset of the plurality of multicast video streams before the requested handoff is complete.
