A Wireless communication s stem (100, 200) Comprises an infrastructure element that allocates wireless resources to one of a plurality of wireless communication units (112-116) dependent upon an operational state of the wireless communication unit. The infrastructure element transitions the wireless communication unit between a plurality of operational states based on a variable, service or quality of service accessed by the wireless communication unit. The transitional, preferably, used in a Radio Resource Controller (RRC) state model, are based on the QoS class of the service that, the communication unit is using. An improvement in signalling load results from reduced signalling procedures required for mobility management, session management and RRC connection management.

In a method for transmitting service information between network nodes in a wireless system providing one or more multimedia broadcast/multicast service (MBMS), when one terminal is moved from a first network node to a cell managed by a second network node, the first network node receives status information of the cell from the second network node, and when the specific terminal is moved into the cell, the first network node selectively transmits an MBMS connection request message to the second network node. In this case, the status information includes MBMS service area information of a neighboring cell with respect to the MBMS service for which the specific terminal has joined and/or information an MBMS function is supported.

It is expected to increase the size of a display panel and the number of tones to be displayed on the display panel, and it is requested to use a display panel displaying M (M>3) types of colors. This requires a large memory capacity and makes a circuit for performing signal conversion complex due to an increase in the amount of data to be subjected to the signal conversion. An image memory stores image data compressed at a fixed compression rate, and the signal conversion is performed on the compressed image data. This technique reduces a memory capacity and simplifies a signal conversion circuit. The signal conversion makes it possible to improve color reproducibility of an image displayed and the quality of the image due to smoothing of the outline of the image. In the case of a display panel having sub-pixels displaying M types of colors, the signal conversion is performed on a compressed signal for each sub-pixel to improve the quality of an image.
