Abstract:
1. A computer-implemented method of transmitting supplemental information in Improved Multi-Band Excitation (IMBE) voice blocks in a transport network, the method comprising: identifying an IMBE voice block with unused octets; revising a frame type identifier associated with the identified IMBE voice block to identify the IMBE voice block as an enhanced IMBE voice block by replacing a first hexadecimal digit of a frame type of the identified IMBE voice block with a second hexadecimal digit that is different from the first hexadecimal digit; selecting at least one of the unused octets to act as a control field; assigning values to a first number of bits in the control field to identify a parameter type; assigning values to a second number of bits in the control field to indicate that appended data is one of: the first data segment of the parameter, the last data segment of the parameter, or an intermediate data segment of the parameter; assigning values to other octets of the unused octets according to the parameter value and metadata describing aspects of the parameter value, thereby completing the assembly of an enhanced IMBE voice block; and transmitting the enhanced IMBE voice block.
