    Abstract: PROBLEM TO BE SOLVED: To control access to an uplink link so as to prevent increase of failed access of subscriber's terminals to a radio communication system. SOLUTION: To easily maintain the target performance an uplink and a desired service area map of the uplink, and control an access by a subscriber terminal 24 to the radio communication system 11, a radio communication system 11 measures a first and a second performance indicator for the uplink to a base station 10 which the subscriber terminal 24 is searching for so as to access. A blocking threshold is established based on the second performance indicator. The radio communication system 11 determines whether or not to allow access by subscriber terminal 24 based on a comparison between the measured first performance indicator and the established blocking threshold.

    Abstract: PROBLEM TO BE SOLVED: To remarkably reduce reaction delay by determining whether or not each backward link data packet received from a first base station is to be contained in the reconstituted frame of backward link data through a data selecting function part on the basis of at least one of assigned time lag and assigned sequence number. SOLUTION: A forward link RLP transfer function is executed by a method distributed to a forward link RLP (BE/RLP) in the base station and a forward link RLP transfer function (FS/RLP) in a selective frame distributing function element. The FS/RLP function element divides incoming forward link data into RLP data unit size and assigns serial original RLP numbers to each segment. Continuously, the FS/RLP function element transfers the forward link data to the BS/RLP function element together with this serial number information. Physical layer framing is performed by the BS/RLP function element.

    Abstract: PROBLEM TO BE SOLVED: To provide a hierarchical cell layer system that can effectively utilize a frequency resource. SOLUTION: In an embodiment, when a mobile unit is connected to a cell of a first cell layer, a timer is started, and when the mobile unit is disconnected from the cell, the timer is stopped. An interlayer handoff system decides whether the mobile unit is to be served by other cell layer, depending on the time when the mobile unit stays in the cell of the first layer or on its function. For example, a network compares the value of the timer or its function with a threshold, so that number of handoff times is at a level or lower at each cell layer.
