Methods, systems, and computer program products for silence insertion descriptor (SID) conversion
First Claim
1. A method for silence insertion descriptor (SID) conversion, the method comprising:
- receiving a wireless frame, the frame identifying a first node as a frame source and a second node as a frame destination;
determining whether tandem-free operation (TFO) is applicable;
responsive to a determination that TFO is applicable, determining whether the frame is a SID frame;
responsive to a determination that the frame is a SID frame, determining whether the SID format used by the first node is incompatible with the SID format used by the second node; and
responsive to a determination that the SID format used by the first node is incompatible with the SID format used by the second node, converting the frame from the SID format used by the first node to the SID format used by the second node and sending the converted SID frame to the second node.

6. A method for silence insertion descriptor (SID) conversion, the method comprising:
-
receiving a wireless frame, the frame identifying a first node as a frame source and a second node as a frame destination; identifying a first codec used by the first node and a second codec used by the second node, and determining whether one of the first and second codecs comprises a second generation global system for mobile enhanced full rate (2G_GSM_EFR) codec and the other of the first and second codecs comprises a third generation global system for mobile enhanced full rate (3G_GSM_EFR) codec; responsive to a determination that the codecs comprise a 2G_GSM_EFR codec and a 3G_GSM_EFR codec, determining whether the frame is a SID frame; responsive to a determination that the frame is a SID frame, determining whether the SID format used by the first node is incompatible with the SID format used by the second node; and responsive to a determination that the SID format used by the first node is incompatible with the SID format used by the second node, converting the frame from the SID format used by the first node to the SID format used by the second node and sending the converted SID frame to the second node. - View Dependent Claims (7, 8, 9)

10. A system for silence insertion descriptor (SID) conversion, the system comprising:
-
a control module for receiving a wireless frame, the frame identifying a first node as a frame source and a second node as a frame destination, and for determining whether tandem-free operation (TFO) is applicable; and a SID conversion module, operatively associated with the control module, for determining whether the frame is a SID frame, and, responsive to a determination that the frame is a SID frame, determining whether a SID format used by the first node is incompatible with a SID format used by the second node, and, responsive to a determination that the SID format used by the first node is incompatible with the SID format used by the second node, converting the frame from the SID format used by the first node to the SID format used by the second node and sending the converted frame to the second node. - View Dependent Claims (11, 12, 13, 14)

15. A computer program product comprising computer executable instructions embodied in a non-transitory computer readable medium for performing steps comprising:
-
receiving a wireless frame, the frame identifying a first node as a frame source and a second node as a frame destination; determining whether tandem-free operation (TFO) is applicable; responsive to a determination that TFO is applicable, determining whether the frame is a SID frame; responsive to a determination that the frame is a SID frame, determining whether the SID format used by the first node is incompatible with the SID format used by the second node; responsive to a determination that the SID format used by the first node is incompatible with the SID format used by the second node, converting the frame from the SID format used by the first node to the SID format used by the second node and sending the converted SID frame to the second node.
