PACKET LATENCY REDUCTION IN MOBILE RADIO ACCESS NETWORKS

摘要

Systems, methods, apparatuses, and computer program products for packet latency reduction in mobile radio access networks. One method may include, when a buffer of a first sublayer of a wireless access link is empty and there is a new data unit in the first sublayer or when the first sublayer buffer is not empty and a data unit leaves a second sublayer buffer, comparing the number of data units currently stored in the second sublayer buffer with a queue length threshold that defines a total amount of space in the second sublayer buffer. When the number of data units currently stored in the second sublayer buffer is less than the queue length threshold, the method may also include transferring the data unit from the first sublayer to the second sublayer.
