摘要:
A remote machine (10) communicates with a server (24). A mobile telecommunications module (14) is used to send a unstructured supplementary services data (USSD) message from the remote machine, and the remote machine then switches off. By polling the server (24), using USSD, the mobile telecommunications module (14) can be kept normally off, saving power.

A method in a user equipment (110) and a user equipment (110) for setting a timeout value, indicative of a duration during which a value related to radio transmissions is to be reused by the user equipment, are provided. The user equipment obtains a timeout value, which is based on mobility information indicating mobility of the user equipment. Then, the user equipment sets the timeout value. Furthermore, a method in a radio network node (120) and a radio network node (120) for setting a timeout value, indicative of a duration during which a value related to radio transmissions is to be reused by the radio network node, are provided. The radio network node obtains a timeout value, which is based on mobility information indicating mobility of the user equipment. Then, the radio network node sets the timeout value for the user equipment.

A method of saving power in a wireless network can include determining a plurality of stations associated with an AP. The AP can create station groups using group selection logic. Notably, the group selection logic is transparent to the plurality of stations. A plurality of TIMs can then be sent, each TIM allowing only one station group access to a channel during a predetermined time interval, such as a beacon interval. In another method, a station can determine its sleep duration based on at least one of first information from the TIM to generate random sleep duration, second information regarding previous operation of the station, and third information regarding a status of the station. The first, second, and third information can include the number of stations associated with the AP and having buffered data based on the TIM, historical collisions, and power status.

摘要:
A method and system for selecting a thermally optimal airlink for a portable computing device includes monitoring a temperature of the portable computing device as well as determining if the portable computing device has reached a threshold temperature range. Next, an estimated volume of data to be sent over one or more airlinks may be calculated in addition to determining an estimated duration for the data using one or more airlinks. A quality of service needed for the data in connection with the one or more airlinks may be determined. With this estimated data, one or more available airlinks for the data to be transmitted may be compared. After this comparison, one or more thermally optimal airlinks may be selected based on the estimated volume, estimated data rate, and estimated duration. Determining if the portable computing device is proximate to an operator may be used when considering airlinks.

A wireless sensor module (2) includes (i) an acceleration sensor (11), (ii) a wireless communication section (13) for wirelessly transmitting measured data generated by the acceleration sensor (11) and receiving a radio signal, (iii) a MCU (12), and (iv) an electric power storage device (15). The MCU (12) secures an idle period(s) of time in a series of operations for processing the measured data. This makes it possible to prevent an output voltage of an electric power supply section from becoming less than an operable minimum voltage.
摘要:
Apparatuses and methods for controlling a manner of delivering content to a content user in a mobile telecommunication network are provided. The content is sent to the content user using first a first transmission rate when the content user is in a first radio state and uses a first battery power, and then using a second transmission rate that is lower than the first transmission rate, when the content user is in a second radio state and uses a second battery power that is smaller than the first battery power. The sending is performed such as, (A) while delivering the content, an amount of the content already received by the content user to exceed an amount of the content used by the content user, and (B) to minimize an energy used by the content user during delivery.
