Abstract
A method is disclosed of optimizing speech quality in a mobile radio system by using if possible a tandem free operation mode for a mobile-to-mobile call. Because the tandem free operation mode is impossible in the case of a coding mode that is unauthorized for that operation mode, instead of using a tandem operation mode in this case, the tandem free operation mode is used, if possible, with an authorized coding mode, provided that the authorized coding mode is supported.

A method of optimizing speech quality in a mobile radio system by using if possible a tandem free operation mode for a mobile-to-mobile call, in which method, because said tandem free operation mode is impossible in the case of a coding mode that is unauthorized for that operation mode, instead of using a tandem operation mode in this case, said tandem free operation mode is used, if possible, with an authorized coding mode, provided that said authorized coding mode is supported.
A mobile radio system for implementing a method of optimizing speech quality in a mobile radio system by using if possible a tandem free operation mode for a mobile-to-mobile call, in which method, because said tandem free operation mode is impossible in the case of a coding mode that is unauthorized for that operation mode, instead of using a tandem operating mode in this case, said tandem free operation mode is used, if possible, with an authorized coding mode, provided that said authorized coding mode is supported, in which system a tandem free operation mode is used if possible for a mobile-to-mobile call, and, if said tandem free operation mode is not possible in the case of a coding mode that is unauthorized for that operation mode, it includes means for, instead of using a tandem operation mode in this case, using said tandem free operation mode, if possible, with an authorized coding mode, provided that said authorized coding mode is supported.
