A lossless call may be established over a wireless radio network by determining, at a target subscriber device during a received call, that one or more identified media items in a stream of media items of the call being received over a first radio channel was not successfully received, and responsively: continuing to receive first subsequent media items of the call and buffering, instead of rendering at the target subscriber device, the first subsequent media items, requesting the identified media items, receiving by the target subscriber device via an established second radio channel, different from the first radio channel, the identified media items, re-ordering the identified media items chronologically with respect to the buffered first subsequent media items to create the re-ordered subsequent media stream, and rendering, by the target subscriber device, the re-ordered subsequent media stream at a first increased relative rate. |

1. A method for achieving a lossless call over a wireless radio network, the method comprising:
receiving, by a target subscriber device during a received call, media items in a stream of media items received over a first radio channel, and rendering the media items at a nominal rendering rate lower than a first increased relative rendering rate; determining, by a target subscriber device during the received call, that one or more identified media items in the stream of media items of the received call being received over the first radio channel was not successfully received, and responsively:
continuing to receive, by one of an infrastructure controller and the target subscriber device via the first radio channel, first subsequent media items of the received call and buffering, and refraining from rendering at the target subscriber device, the first subsequent media items;requesting, by the target subscriber device, the identified media items;one of:
receiving, by the target subscriber device via a second radio channel, different from the first radio channel and established at a time of establishment of the received call or responsive to the determining that the one or more identified media items was not successfully received, the identified media items and re-ordering, by the target subscriber device, the identified media items chronologically with respect to the buffered first subsequent media items to create a re-ordered subsequent media stream; andreceiving, by the target subscriber device via a second radio channel, different from the first radio channel and established at the time of establishment of the received call or responsive to the determining that the one or more identified media items was not successfully received, a re-ordered subsequent media stream including the identified media items chronologically ordered with respect to the buffered first subsequent media items;rendering, by the target subscriber device, the re-ordered subsequent media stream at the first increased relative rendering rate; and subsequently receiving, by the target subscriber device via the first radio channel, second subsequent media items of the received call over the first radio channel and rendering, by the target subscriber device, the second subsequent media items at the nominal rendering rate. |
