Method and apparatus for managing packet data loss in a wireless network
First Claim
1. A method for managing packet data loss in a wireless network comprising;
- receiving, by a packet data destination from a packet data source, a flow of packets for a packet data service instance;
transmitting, by the packet data destination to the packet data source, an indication to suspend transmitting the flow of packets for the packet data service instance; and
transmitting, by the packet data destination to the packet data source, an indication of how to process packets for the packet data service instance while the flow transmission is suspended,wherein the indication of how to process packet s comprises signaling that provides packet processing instructions for the packet data source,wherein the packet processing instructions for the packet data source comprise an instruction from the group consisting of an instruction to buffer packets for the packet data service instance while the flow transmission is suspended, an instruction to buffer packets for the packet data service instance for an indicated period of time while the flow transmission is suspended, an instruction to discard packets for the packet data service instance while the flow transmission is suspended, and an instruction to resume flow transmission for the packet data service instance after an indicated period of time.

Abstract
Various embodiments are described to address the need for more effective management of packet data loss in wireless communication systems. When a packet data destination (131) that is receiving a flow of packets for a packet data service instance indicates to the packet data source (141) of the flow that the flow should be suspended, it also indicates to the source how to process packets for the service instance while the flow transmission is suspended. For example, the packet data destination may indicate an event or condition that is triggering the flow suspension, the source can then begin buffering packets, discarding packets, starting timers, and/or taking other packet processing actions to manage packet data loss in view of the packet data destination'"'"'s indication. Alternatively, the packet data destination may explicitly indicate the packet processing actions the source should take while the packet flow is suspended.
