Abstract: Upon receiving ( 101 ) a vocoded voice frame and detecting ( 102 ) that the received vocoded voice frame comprises an erased frame, one automatically replaces ( 103 ) the erased frame with a valid frame having at least one error condition. In a preferred approach this error condition is one that is known to cause a receiving target platform to invoke a corresponding erasure process with respect to the valid frame when received.

Abstract: An apparatus (200) checks voice quality when in a vocoder bypass mode. If the voice quality level is beyond an acceptable range, the apparatus (200) ends the vocoder bypass mode and returns to tandem vocoding. For example, a vocoder bypass controller (206) includes a speech quality detector (225) that determines the speech quality level of speech information based on at least one of detected volume level, echo level and noise level of the speech information. The vocoder bypass controller (206) with the speech quality detector (225) outputs a speech quality-based vocoder bypass control signal (236) to selectively activate or deactivate a vocoder bypass operation in response to the speech quality-based vocoder bypass control signal (236). In another embodiment, a network element for communicating speech packets includes an incoming decoder (512) and a speech quality detector (514) operative to determine the speech quality level of incoming speech packets. The speech quality detector (514) determines whether to activate speech quality enhancement operations in response to a determined speech quality level of incoming speech packets.

Abstract: Embodiments of the present invention address the need to support enhanced transcoding functionality by various improvements to the Real Time Protocol (RTP). Enhanced RTP (200, 300, 400) can be used by base station controllers (114, 124) in a radio access network (106) to communicate bearer traffic to core network media gateways (160) containing transcoders (161). Embodiments are described that can provide some or all of the following improvements: UTC time reference for vocoders, errored radio frame indication in conjunction with the decoded radio frame information, encoder analysis frame (i.e., time) alignment, enhanced support for discontinuous transmission, support for Tandem Free Operation (TFO), and support for vocoder rate control (a.k.a. Dim & Burst).

Abstract: A communication system (100) provides a clear channel link for transport of encrypted payload across a network (140) of the communication system. When a source access network (106) receives, via an air interface (104), a frame that is formatted pursuant to an air interface protocol and that comprises encrypted payload, the source access network demultiplexes the frame to separate the encrypted payload and assembles an Intersystem Link Protocol (ISLP) frame that comprises the encrypted payload. The source access network adds a link layer header to the ISLP frame that identifies one or more of frame type information and a sequence value associated with the frame and conveys the ISLP frame and added header to across the network, for example, to a destination access network (126). Based on the added header, the source and destination access networks are able to perform clear channel synchronization.
