For the use of mobile phones and terminals two modes of usage could be distinguished in general: RX mode – the mobile phone is the called party and TX mode – the mobile phone is the calling party. Also three modes of operational status can be distin- guished for the mobile phone: off mode – the mobile phone is deactivated, on standby – the mobile phone is waiting to enter another mode and on operating – the mobile phone is used in RX- or TX mode. Because most user receive and/or make only a few calls a day the mobile phone is very often on standby what means that the mobile phone needs to keep a permanent linkage to the next base station. This re- sults in a high power consumption of the mobile phone. In the case that the user wants to behave as an “TX only user”, what means that he only wants to make outgoing calls and don’t want to receive any incoming call, the mobile phone only needs to link the next base station in the case of a outgoing call.
