Patent attributes
Apparatus communicating with a mobile and a remote base station. The mobile is assumed to have a coding unit capable of operating in at least one mode selected from a set, each mode in the set being associated with a coding requirement. The set is characterized in that it has at least one mode that is associated with a greater coding requirement than a “designated” mode. Also, the apparatus comprises a control entity suitable to establish a tandem-free transfer of data received from the mobile to the remote base station. The control entity is operative to send control information to the mobile to cause the coding unit therein to operate in the designated mode prior to establishment of the tandem-free transfer. By forcing the mobile to operate in the designated mode, it is guaranteed that the tandem-free transfer can be achieved.
