If a wireless resource congestion occurs, the wireless resources of the entire system are used efficiently to reduce a disconnection of communication with a congested sector and a state in which a new call cannot be originated nor terminated. A base station control apparatus compares the wireless resource usage amount of each sector of each base station with values stored in a wireless resource threshold table. If a sector of a base station is in the light congestion state, the neighbor search window size of a sector specifying the congested sector as a neighbor is changed to restrict a soft hand-over to the congested sector. If a sector of a base station is in the heavy congestion state, a mobile station which is communicating in the congested sector and receiving radio waves of another sector with stability is subjected to a forced soft hand-over.

A packet recovery method of the present invention is a packet recovery method upon loss of a plurality of packets transmitted from a first node 111 to second node 112 through a network in the order of sequence numbers assigned to each of said packets, wherein second node 112, upon detection of a loss of a packet transmitted from first node 111, transmits an acknowledgement message, including a sequence number of a packet whose receipt has been confirmed or whose loss has been detected and including information on the lost packet, to first node 111 through the network. Then, first node 111, upon receipt of the acknowledgement message from second node 112, assigns a sequence number that is different from that of any of the plurality of packets to a retransmission packet which is a packet to be retransmitted, and subsequently, transmits an acknowledgement-to-acknowledgement message attached to the retransmission packet through the network for notifying that the acknowledgement message has been received to second node 112.

There is disclosed a transflective liquid crystal display having pixels each including a reflective region and a transmissive region. The aperture ratio of the pixels can be enhanced. End portions of two adjacent color filters are overlapped to form an optically shielding portion for each pixel.

In a multiprocessor system in which a plurality of processors share an n-way set-associative cache memory, a plurality of ways of the cache memory are divided into groups, one group for each processor. When a miss-hit occurs in the cache memory, one way is selected for replacement from the ways belonging to the group corresponding to the processor that made a memory access but caused the miss-hit. When there is an off-line processor, the ways belonging to that processor are re-distributed to the group corresponding to an on-line processor to allow the on-line processor to use those ways.

Even when all of usable sessions are in use, a communication can be established for a new session and the interrupted session is automatically restored. Information on degrees of importance of communication sessions and information of restoration requirement are set in advance and stored in a session importance table in association with identifier (URI) of communication initiating terminals and identifier of destinations of communication. When a connection request for a session having a high degree of importance such as an emergency session is received, the session having the lowest degree of importance is selected and interrupted. Information of the interrupted session such as the communication initiator identifier and the communication destination identifier is stored in a session restoration table. The session is automatically restored as soon as a session resource becomes unoccupied according to the communication initiator identifier and the communication destination identifier stored in the session restoration table.
