Timing control information, especially scheduling information, is transmitted between single network devices in a wireless network. Timing control information is usually time-critical information since communication parameters may be changing rapidly in wireless networks. The invention provides a method to transmit the time-critical and up-to-date timing control information to a recipient just-in-time.

A RF-ID based wireless terminal includes a reader device with transponder functionality implementing ECMA 340 standard for near field communication and has shortened session set-up and user identification. The reader device is operable in an active communication mode or a passive communication mode. During the active mode, one RF-ID tag reader simulates a RF-ID tag while the other simulates a RF-ID tag reader. The reader includes a transponder, which operates during periods of time when the reader is not energized. A radio frequency interface provides signal for operation of the reader in the reader operation mode or transponder mode of operation. An RF-ID reader upon receiving a response signal from a semi-passive or active RF-ID tag of reader emulating a tag informs the terminal CPU which instructs the short-range communication to enter e.g. a page scanning mode which shortens session set-up time and user identification.

Method of prioritising the usage of slotted links by single network devices in a wireless network for adapting to varying traffic loads, comprising the steps of pre-setting a distribution of priorities for using a link to predetermined values, monitoring the current link usage, and adapting the priorities in accordance with the monitored usage.

The method, terminal and computer program product determine the context of the mobile terminal associated with the RFID reader and adjusts the power consumption of the RFID reader based upon the determined context relative to at least one previous context determination. To adjust the power consumption, the frequency at which the RFID reader is actuated may be altered. Thus, the power consumption of the RFID reader may be reduced when no change in the context of the mobile terminal is determined and/or may be increased when a change in the context of the mobile terminal is determined. Due to the adjustment of power consumption by RFID readers, power is conserved in the mobile terminals associated with RFID readers, which permits the mobile terminals and RFID readers to operate longer without requiring charging or replacement of the power supply.
