  • the cell phone device If you are not constantly in such a cell phone cell, but are moving with the cell phone device in a car, for example, the cell phone device tries to register itself cyclically in a WLAN network, which leads to increased power consumption and reduced standby time of the cell phone device leads.
  • the present invention is therefore based on the object of providing a method for reducing the power consumption of a mobile terminal or a mobile terminal with reduced energy consumption, which ensures a reduction in power consumption even with low network coverage and / or small mobile radio cells.
  • the mobile terminal can be any type of mobile terminal with the capability for mobile communication such as, for example, mobile radio terminals or PDAs (Personal Digital Assistants).

  • the radio cell plan is preferably a database which contains an association between the available mobile radio standard and the local position. So with help of the radio cell plan can be determined where a respective mobile radio standard is available.

  • a registration attempt is preferably made in a radio cell in which the mobile terminal is located after its activation.

  • the at least one mobile radio module is activated only when the mobile radio standard of the mobile radio module is available at the current local position of the mobile terminal. If the mobile terminal can be operated, for example, with the GSM standard and the UMTS standard, the corresponding mobile radio module is activated or a registration attempt is only made if the mobile terminal is in a radio cell with the respective standard.

If the mobile terminal is inside or on the edge of a WLAN radio cell, the WLAN components (software stack and WLAN hardware) are activated. Now broadband services can be activated and accrued data such as larger e-mails can be sent quickly until the WLAN connection breaks down again.
