Abstract: Methods, systems and devices for improving discontinuous reception (DRX) in wireless telecommunication networks are disclosed. According to an embodiment, a retransmission buffer status report (BSR) timer is implemented in a user equipment (UE) as an attribute that is configurable for each logical channel of the UE. According to another embodiment, a data flush token is implemented as a logical channel attribute in a UE in order to expedite emptying of the UE's uplink buffer. According to another embodiment, improvements are provided to the manner in which a UE determines to cancel regular BSRs. According to other embodiments, features are implemented at a base station such as an E-UTRAN Node B (eNB) to improve downlink and uplink transmission scheduling between the base station and a UE. According to further embodiments, improved methods of detecting and handling late and delayed BSRs are implemented at a base station. The disclosed embodiments promote improved battery life of a UE as well as improved network data performance.

Abstract: Dynamic control of the length of time that an RRC connection exists is implemented based on the known and anticipated data needs of the UE. More specifically, the lifetime of the RRC connection may be a) initially set, b) extended, or c) shortened, even to the point of substantially immediately releasing it, based on the expected data transmission needs of the UE. This dynamic control is implemented by elements of the core network which are aware of the known and anticipated data needs of the UE. The UE needs are a function of the applications running on the UE. In one LTE-based embodiment, the RRC release timer is responsive to the Policy and Charging Rules Function (PCRF), which can access information about the applications that are running at the UE. In another embodiment, the RRC release timer is responsive to the Policy and Charging Enforcement Function (PCEF).

Abstract: A method and/or device that determines when an erroneous voice packet has been received over the air interface of a cellular communication network, such as a 4G LTE network, and initiates a voice communications re-establishment procedure when a triggering event—based on receptions of erroneous voice packets—has occurred. The voice communications re-establishment procedure is performed to avoid at least a portion of the air interface (i.e., an uplink or downlink of the Uu interface through which the erroneous voice packets have traversed) from becoming non-operational. The triggering event may be the number of consecutive erroneous voice packets received over an uplink or downlink surpassing a threshold or it may be the length of time that has lapsed during receptions of consecutive erroneous voice packets. The triggering event is an indication that an uplink or downlink will most likely become non-operational if voice communications are not re-established.
Abstract translation: 一种确定何时通过诸如4G LTE网络的蜂窝通信网络的空中接口接收到错误语音分组的方法和/或设备，并且当基于接收的触发事件时发起语音通信重建过程 的错误语音数据包。 执行语音通信重建过程以避免空中接口的至少一部分（即，错误语音分组穿过的Uu接口的上行链路或下行链路）变得不可操作。 触发事件可以是在超过阈值的上行链路或下行链路上接收的连续错误语音分组的数量，或者可以是在接收连续的错误语音分组期间已经过去的时间长度。 触发事件是指示如果语音通信不被重新建立，则上行链路或下行链路将很可能变得不可操作。
