    摘要: In the selection of a control channel of a mobile station in a radio zone to which some control channels are assigned as communication channels, the receiving levels of the control channels are sequentially measured and control channel candidates are selected. A check is made to see if a control signal can correctly be received in each of the selected control channel candidates, and if not, the number of signal reception failures in that channel is incremented by 1 in a memory used by the mobile rotation. A channel in which the number of signal reception failures has reached a predetermined value M (an integer equal to or greater than 1) is excluded from the group of control channel candidates, and the other selected control channel candidates are similarly checked to determine whether or not the reception of the control signal is possible in each of them. If the control signal can correctly be received in a given control channel, a check is made to see if the mobile station has moved into a different radio zone, and if not, the mobile station enters the state of waiting for an incoming call in that control channel. If the radio zone of the mobile station has changed, the numbers of signal reception failures in all the control channels are reset in the memory, so that all the control channels are made candidates to be selected next as a control channel of the radio zone in which the mobile station is currently located.

    摘要: When a mobile station (4) staying in a first paging zone (1) begins communication with a network through a base station by using a paging channel (P1) which is specific to the paging zone (1) and one of speech channels (S11-S20), and finishes the communication in a paging zone (2) after moving from the zone (1) to the zone (2), the paging channel in the waiting state after the speech in the zone (2) is not (P1), but (P2) which is specific to the zone (2). In order to assure that paging channel (P2), a base station in the zone (2) informs the mobile station (4) the paging channel (P2) which should be used in the waiting state in the disconnect signal. Thus, no switching of a paging channel in waiting state because of low receive level of the paging channel signal is necessary, and a quick service after previous speech is possible.

    摘要: Logic output data of a plurality of channels simultaneously obtained from a circuit under test are sequentially input in a memory, and after inputting a predetermined amount of such data, they are compared with corresponding expected values. The input data are divided into blocks, each including a plurality of data. Whether a mismatch is present in the comparison results for each block is indicated by a respective block element, and such block elements are displayed in a predetermined arrangement. It is also possible to provide a conventional list display including the input timing corresponding to the comparison results in which a mismatch is present.
