Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.

Method and apparatus for dormant mode support with paging

One aspect of the present invention regards a method of coordinating the handoff of a mobile carrier between a first access network and a second access network, the method including handing off from a first access network that the mobile carrier is currently operating within to a second access network and building physical access network topology based on the handing off without input from either the first access network or the second access network.

To provide a data transmitter-receiver bidirectional transmitting system, and data transmitting-receiving method capable of reducing influences of a transmission delay when performing bidirectional communication with an other-communication-party apparatus in an environment in which various states are dynamically changed depending on time. A data obtaining portionof a terminalobtains positional directional information D(Tn) and a time information obtaining portionobtains time information Tn. The terminalstores D(Tn) and Tn in a memory portionand a transmitting portiontransmits D(Tn) and Tn to a server. A data generating portionof the servergenerates stereophonic data S(Tn) by using D(Tn), a time information copying portioncopies Tn, a transmitting portiontransmits S(Tn) and Tn to the terminal. A data obtaining portionof the terminalobtains positional directional information D(Tm), the time information obtaining portionobtains time information Tm, and a correcting portioncorrects the difference between D(Tm) and D(Tn) to generate S'(m).

A speaking period required for a voice recognition processing is detected with a simple and robust approach. A speaking period is detected based on an EMG generated when a speaker speaks. A large amplitude is observed in an EMG as muscular activity is caused when a speaker speaks. By observing this, a speaking period can be detected. The EMG can be measured from the speaker's skin via electrodes provided on a mobile-type terminal. Since a mobile-type terminal is usually pressed to the skin for use, affinity between this use form and the present invention is very high.
