摘要： A method for initiating a codec rate change during a VoIP call by a wireless communication device is disclosed. The method can include the wireless communication device establishing a first codec rate for use in the VoIP call during a call establishment phase; using the first codec rate to encode voice data for transmission during a first portion of the VoIP call; determining a channel quality while using the first codec rate; determining that the channel quality satisfies a threshold for requesting a codec rate change; requesting a codec rate change from the first codec rate to a second codec rate in response to the channel quality satisfying the threshold; and using the second codec rate to encode voice data for transmission during a second portion of the VoIP call.

摘要： This application presents techniques for an LTE user equipment (UE) to use an extended service request (ESR) extension for LTE TDD to FDD redirection for mobile originated and mobile terminated VoLTE calls. These techniques include the UE informing the network that it supports the particular features of the ESR extensions presented. Once the UE attaches to the network, a radio resource control (RRC) message can be sent to indicate that the UE supports the new ESR extension, after which the UE can use the new ESR extension to facilitate an LTE TDD to FDD redirection for the VoLTE call.

摘要： Apparatus and methods of performing a network cell transition for a voice over long term evolution (VoLTE) capable mobile device. Initially, the mobile device can detect a call initiation event. Thereafter, the mobile device determines whether a radio signal power associated with its serving LTE network base station is less than a radio access technology (RAT) specific threshold (i.e., an LTE-specific threshold). In a scenario where the radio signal power is less than the RAT-specific threshold the mobile device can effectuate a transition to an available neighbor network base station employing a legacy RAT, prior to establishing a voice call. When the mobile device is in a radio resource control (RRC) connected mode the network cell transition may be associated with an induced network handover procedure. Alternatively, when the mobile device is in an RRC idle mode the network cell transition may be associated with network reselection procedure.
摘要翻译：对具有长期演进（VoLTE）能力的移动设备的语音执行网络小区转换的装置和方法。最初，移动设备可以检测呼叫发起事件。此后，移动设备确定与其服务LTE网络基站相关联的无线电信号功率是否小于无线接入技术（RAT）特定阈值（即，LTE特定阈值）。在无线电信号功率小于RAT特定阈值的情况下，在建立语音呼叫之前，移动设备可以实现对使用传统RAT的可用的相邻网络基站的转换。当移动设备处于无线电资源控制（RRC）连接模式时，网络小区转换可以与诱导的网络切换过程相关联。或者，当移动设备处于RRC空闲模式时，网络小区转换可以与网络重选过程相关联。
