摘要：
A method, apparatus, and computer program product can provide for procedures at an access terminal (510) for handling the delivery of packets from the MAC entity (800) to the RLC entity (312), with an aim to reduce the occurrence of RLC resets that might otherwise be caused by out-of-order processing of control packets following a serving cell change. In one example, a MAC entity (800) may insert an identifier into a packet delivered up to the RLC entity (312), to indicate whether the packet arrived from the current primary serving cell. In another example, a serving cell change procedure may include steps to flush a queue at the MAC entity (800) and kill any running reordering release timers (616). In these ways potential problems caused by out-of-order control packets can be reduced or avoided.
摘要（中）：
方法，装置和计算机程序产品可以提供在接入终端（510）处理从MAC实体（800）到RLC实体（312）的分组传送的过程，目的是减少RLC的发生 可能由于服务小区更改后控制数据包的无序处理而导致的复位。 在一个示例中，MAC实体（800）可以将标识符插入到传送到RLC实体（312）的分组中，以指示分组是否从当前主服务小区到达。 在另一示例中，服务小区改变过程可以包括在MAC实体（800）处刷新队列并杀死任何正在运行的重新排序释放定时器（616）的步骤。 在这些方面，可以减少或避免由无序控制分组引起的潜在问题。
