Definitions
- various types of devices i.e. a digital camera, a printer, a keyboard, an MP3 player, a personal digital assistant (PDA), a mouse, a digital subscriber line (xDSL), Access Point (AP) and a scanner, configures the WPAN as a coordinator, centering around a computer.
- Each of the devices is connected by a wireless method using a predetermined frequency band, instead of a wired method.
- the WiMedia may use two types of access methods, a Distributed Reservation Protocol (DRP), and a Prioritized Contention Access (PCA).
- DRP Distributed Reservation Protocol
- PCA Prioritized Contention Access
- FIG. 5 is a diagram illustrating a frame structure of a GWS transmitted in a device located in a WPAN according to an exemplary embodiment of the present invention
- a value recorded in the LWS period field 431 includes period information of a superframe 400 where a corresponding device is awake. Specifically, when the corresponding device is in sleep mode for two superframe durations, and when the device is in awake mode for subsequent superframe durations, the value recorded in the
- the establishing of the value in the GWS Countdown field 532 will be described in detail below.
- a value of the GWS period field 531 included in GWI IE 615 of GWI 610 is three
- a value of the GWS period field 531 included in the GWI IE 615 is three and an initial value of the GWS Countdown field 532 is two.
- a value of the GWS period field 531 included in GWI IE 625 of GWS 620 is three and a value of the GWS Countdown field 532 becomes one.
- a value of the GWS period field 531 included in GWI IE 635 of the GWS 630 is three and a value of the GWS Countdown field 532 becomes zero.
- GWS Countdown field 532 becomes zero, all devices communicating with a corresponding device in the WPAN, including a device acting as a coordinator in the WPAN, wake up. After the devices are awake, when the devices, maintained in the awake mode during a predetermined superframe duration, return to sleep mode, a value of the GWS period field 531 included in the GWI IE 645 of the LWS 640 is established as three, and an initial value of the GWS Countdown field 532 is established as two. With respect to a subsequent GWS, the operations described above are repeated.
- the values of GWS field Countdown 532 are taken as an example for convenience of explanation, the initial value of the GWS Countdown field 532 and the value of the GWS Countdown field 532 where the corresponding devices are awake may be established as different values. Modification or variation of values of the GWS Countdown field 532 would be appreciated by those skilled in the art.
- Method of controlling awake/sleep mode using LWS/GWS By referring to FIG. 7, a method of controlling awake/sleep mode between devices located in the WPAN according to the present invention will be described using the LWS and the GWS described by referring to FIGS. 4 through 6.
- FIGS. 8 and 9 a method of operation of a device in the WPAN, where the method of controlling awake/sleep mode, using the LWS/GWS, is performed, and a configuration of the device will be described in detail.
- the values of the LWS period and the LWS Countdown field established in operation 810 is recorded in an LWI IE of a beacon slot of the LWS and an LWS in the WPAN is broadcasted.
- the LWI IE includes the LWS period field and the LWS Countdown field, and values of the LWS period and the LWS Countdown are recorded in each field.
- operation 830 when a subsequent superframe is transmitted, a value of one less than a value of the LWS Countdown field in a prior superframe is included in the LWI IE, and is repeatedly broadcasted.
- whether the value of the LWS Countdown field reaches zero or not is determined, and when the value of the LWS Countdown field reaches to zero, the device wakes up in operation 850.
- the PAL 900 may include a local parameter analysis unit 920, an LWS period management unit 930, a Countdown unit 940, a superframe generation unit 950, a control unit 960, and a GWS period/Countdown management unit 970.
- the PHY 910 controls physical transmission and an interfacing with a wireless media.
- the local parameter analysis unit 920 determines an LWS period by analyzing the local parameter of a corresponding device located in the WPAN.
- the local parameter may be at least any one of current traffic information for the device, expected traffic information, channel condition of the WPAN, or a power level of the device.
- a algorithm for determining the LWS period by analyzing the local parameter may be variously designed.
- the LWS period management unit 930 maintains a value of the LWS period determined in the local parameter analysis unit 920, or a value of the LWS period inputted from a user, as a setting value. According to the values of the LWS period, a value of the LWS Countdown included in the LWI IE of the LWS is determined.
- the superframe generation unit 950 broadcasts the values of the LWS period and the LWS Countdown to the WPAN through the PHY 910 by inserting the values of the LWS period that is maintained in the LWS period management unit 930, and the LWS Countdown that is transmitted from the Countdown unit 940.
- the PAL 900 and the PHY 910 of the configuration of the device in the WPAN are taken as an example described as a functional module performing the method of generating the LWS/GWS and controlling awake/sleep mode, name modification, also segmentation/combining or the like of the functional module using the LWS/GWS of the present invention may fall into a category of the present invention.
- a superframe transmitted/received in a wireless communication which can minimize data traffic in a WPAN since each of devices is informed of an awake/sleep mode of other devices in a neighborhood by broadcasting a local wakeup interval (LWI) in the WPAN.
- LWI local wakeup interval
- a superframe transmitted/received in a wireless communication which can maximize power efficiency of a transmission (Tx) device when transmitting to a target reception (Rx) device since each of devices is informed of an awake/sleep mode of other devices by broadcasting a local wakeup interval (LWI) in a WPAN.
- a superframe transmitted/received in a wireless communication which can wake all devices in a WPAN according to a predetermined period by broadcasting a global wakeup interval (GWI) in the WPAN.
- GWI global wakeup interval
- a superframe transmitted/received in a wireless communication which can optimize power efficiency of data traffic and a device in a WPAN since each of devices dynamically controls its awake/sleep mode in the WPAN.
