Abstract: In a method for configuration of a compressed mode in a mobile radiocommunication system, a configuration of a compressed mode defined using the parameters for the compressed mode. The parameters include a transmission gap length (TBVL) and a transmission gap pattern length (TGPL). The transmission gaps are defined in a first transmission time structure specific to a first system and determined relative to a second transmission time structure specific to a second system to permit measures for the second system to be taken in the first system. For each reference configuration, if the duration of the TPGL is such that the transmission gaps occur periodically with fixed position in said second structure, then the TGL is selected to be sufficiently large so that two transmission gaps occur in two of the positions, the closest of which overlap each other with an overlap duration long enough to carry out a measure.

Abstract: A radio base station has a baseband unit (BB) and multiple RF heads (RH1, RH2), which are interconnected by means of a bi-directional two-fiber optical ring (R). Each RF head (RH1, RH2) has a delay counter (31) for determining a propagation delay (tL) on the ring (R) and a variable delay circuit (16, 26) for compensating a difference between the propagation delay on the ring and a predefined target delay (tRR). The delay counter counts (31) the delay between a test signal sent on the first fiber (F1) of the ring to the baseband unit and a received test signal looped back by the baseband unit on the second fiber (F2) of the ring.

Abstract: There is provided a process management system which, when a crash occurs in execution of a processing process, can immediately restart a processing process while holding data used in occurrence of the crash as much as possible. When a determination unit determines that a detected crash is not a crash caused by data used in a processing process, a processing unit reexecutes the processing process in which the crash occurs. When the determination unit determines that the detected crash is a crash caused by the data used in the processing process, an initialization unit initializes the data used in the processing process.
