Publication number: 20160095033Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., UE, suspends a discarding process of data packets associated with a first RAT during tune away by the UE to a second RAT by stopping a discard timer. The UE restarts the discarding process in response to an occurrence of a triggering event. The triggering event may occur when the UE tunes back to the first RAT, or when a duration of the UE tune away to the second RAT exceeds a threshold. The discarding process may be restarted by resuming the discard timer at the point in time where it was stopped or by resetting the timer to zero.Type: ApplicationFiled: September 23, 2015Publication date: March 31, 2016Inventors: Prasad KADIRI, Pavan KAIVARAM, Neelakanta Venkata Seshachalam CHIMMAPUDI, Ammar Taiyebi KITABI, Chintan Shirish SHAH, Aziz GHOLMIEH
