摘要： A wireless communications system includes: a first communications processing section for implementing a dedicated communications function that is only for the first wireless communications scheme; a second communications processing section for implementing a dedicated communications function that is only for the second wireless communications scheme; a shared transceiver section shared by the first communications processing section and the second communications processing section; a scheme selection section for selectively inputting a signal from the first communications processing section or a signal from the second communications processing section to the shared transceiver section; and a communications switching control section for indicating, to the scheme selection section, a scheme to be selected. The communications switching control section determines a switching timing based on frame and sub-frame information from the first communications processing section in an operation of switching from the first wireless communications scheme to the second wireless communications scheme or an operation of searching for a communications target station using the second wireless communications scheme.

摘要： Prior to detection of a start of a session having periodicity in a wireless terminal, the wireless terminal powers on a communication unit that performs wireless communication with a wireless base station, in accordance with a reception timing of receiving a beacon signal once in several times and a generation timing of transmission packets of sessions. After the start of a session having periodicity has been detected in the wireless terminal, the communication unit is only powered on when transmission packets of sessions having periodicity are generated.

摘要： Provided is a network chip that controls issuance of interrupts based on the contents of the received packets. The network chip receives a data packet containing a type that indicates a realtime packet or a not-realtime packet, where the realtime packet needs consideration of delay time, and the not-realtime packet does not need consideration of delay time. The network chip obtains a type by analyzing the received packet. When the obtained type indicates a realtime packet, the network chip stores the received packet into a realtime reception packet buffer, and issues an interrupt to the CPU immediately; and when the obtained type indicates a not-realtime packet, it stores the received packet into a not-realtime reception packet buffer, and issues an interrupt to the CPU after a predetermined time period passes, or after the number of packets stored in the not-realtime reception packet buffer reaches a predetermined number.

摘要： When the communication channel is to be changed, a more optimal communication channel is determined by summing up the results of measuring communication states transmitted from individual wireless terminals A, B, and C and making a collective judgment. Weighting coefficients are set to the individual wireless terminals A, B, and C. Values indicating whether or not the respective communication states of the individual wireless terminals are optimal with channels ch1 to ch4 to be used for communication (which are, e.g., 1, 0, 1, 2 with the respective channels ch1, ch2, ch3, and ch4 for the wireless terminal A and larger as the communication states are less optimal) are multiplied by the weight coefficient (the value of 3). The resulting values are summed up on a per-channel basis and the most optimal communication channel (of which the summed value is lowest) is selected. As a result, wave interference with the other wireless terminal is reduced.
