call. Frequency band or time slot can be changed due to quality degradation or interference, the
associated base stations can be changed due to the mobility of a user in a multi-cell environment.

heard with no message with two seconds interval. The closer to the cell, the more unstable the
call is. Try to move toward other cell.
