Abstract: An energy-conserving mobile station and a means for reducing the energy consumption of a mobile station and to reduce burn-in on the display element, where a part of the liquid crystal display element (LCD) of a mobile station is switched off, when the whole display element is not needed and a limited amount of information is displayed on the switched-on part of the display element (A1). An arrangement according to the present invention can be implemented by e.g. driving the control circuit (DC) of the liquid crystal display that supports the partition of the display element to switch of certain rows of the display element in energy conservation mode and switching them on to be used, when information is desired to be displayed on all of the display element.

Abstract: In TDMA systems it is possible to transmit data on more than one consecutive slot per frame. This introduces increased workloads on the power amplifier of the transmitter of the mobile station. To prevent the power amplifier from overheating, temperature sensing means are incorporated into the mobile station which output to a control system comprising a comparator and feedback means which together regulate the operation of the transmitter if the power amplifier approaches or exceeds it upper rated operating value. Thereby preventing the power amplifier from damage.

Abstract: A method for refreshing memory cells in a dynamic memory includes dividing the information stored therein at a given time into information to be maintained and information not requiring maintenance, wherein at least some of such memory cells containing information not requiring maintenance are left unrefreshed. In the method application programs are executed. The memory cells of the dynamic memory are divided into two or more blocks which can be refreshed irrespective of each other. Information on the location of each application program to be executed is stored, as well as on the quantity of memory allocated by each application program to be executed. In the method it is further determined on the basis of said stored information which of said memory blocks contains information requiring maintenance, wherein other memory blocks remains unrefreshed. The invention also relates to an electronic device.

Abstract: A method and apparatus for updating transmission power class information of a Mobile Station (MS) in a General Packet Radio Services (GPRS) network. The invention updates transmission power class information of the MS in the GPRS network by initiating a Routing Area Update (RAU) procedure in the MS. The RAU procedure includes sending from the MS to a Serving GPRS Support Node (SGSN) of the GPRS network a RAU request message including a MS Radio Access Capability (RAC) Information Element (IE) which includes an IE indicating a new transmission power class of the MS, accepting in the SGSN the IE indicating a new transmission power class of the MS included in the MS RAC of the RAU request message, and delivering to a Base Station (BSS) the IE indicating a new transmission power class of the MS, thereby updating the transmission power class information of the MS at the BSS.

Abstract: A mobile station (MS) that includes an interface card slot (SLOT) to which it is possible to connect either an MMC-card or a small SIM-card. To connect the small interface card a separate adapter the size of an MMC-card is used, or, in addition to the first contact pins for use of an MMC-card, second contact pins for use of a SIM-card are arranged to the interface card slot. The operating voltage of the interface card is selected to fit the currently used interface card. In some embodiments of the present invention at least partially shared contact pins, which have been multiplexed, are being used to connect MMC- and SIM-cards.
