Abstract: 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.

Abstract: Method and apparatus for facilitating return to a first wireless network from a second wireless network by a wireless communication device is provided. A method includes the wireless communication device engaging in data transfer for an application session on the first wireless network; participating in a CSFB procedure to transition from the first wireless network to the second wireless network for servicing a voice connection; buffering data received for the application session before and/or during the CSFB procedure; releasing the voice connection; discontinuing requests for downlink data for the application session in response to termination of the voice connection to provide a gap in data transfer; reselecting to the first wireless network during the gap in data transfer; using the buffered data to continue the application session during reselection; and resuming data transfer for the application session on the first wireless network after completing reselection.

Abstract: 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.
