Power saving method for scanning input signals in a wireless telephone

The telephone intermittently monitors for a received signal. If during a given period of time (a 'third' period of time), longer than the monitoring period (the 'first' period of time), no signal is received, the monitoring period is increased to save power. If, however, during this new, longer, monitoring period (the 'second' period), a signal is received, the mode is returned to the original, shorter monitoring period. In another embodiment, if an input signal is received during the third period of time, the strength of the signal is measured at a 'first mode keeper'. If the signal strength is at or above a threshold value then the first, shorter monitoring period is maintained. Also described is a computer program for causing a computer to control the operation of this system.

The receiver uses compression to transmit acknowledgement messages to multiple terminals. These reduce the size or number of bits of the acknowledgement message, such as by only sending slot identifiers of successfully decoded slots or by using hashing of the terminal identification number.

METHODS AND SYSTEMS FOR CONFIGURATION AND ACTIVATION OF POWER SAVING CLASSES BY A MOBILE STATION IN A SLEEP MODE

Techniques presented herein allow connections with different (albeit possibly similar) scheduling or data delivery services to be aggregated (or 'bundled') into groups, with each group assigned a common Power Savings Class Type. Bundling different connections into common PSC types may reduce the overall number of different sleep windows for active connections, which may help reduce overall power consumption. For example, by automatically activating different PSC types (for different bundles of connections), the reduced number of sleep windows may overlap in a manner that results in the MS spending more overall time in a low power state than when conventional 'unbundled' PSC schemes are utilized.

The invention relates to a transmission apparatus, a control method thereof and an information communication system. When a communication between a camera and a television is performed utilizing a first wireless communication mode which employs high-directional radio transmission, and a second wireless communication mode which employs low-directional radio transmission with lower directivity than that of high-directional radio transmission, the television detects that the communication in the first wireless communication mode has been disconnected and notifies the camera. The camera determines whether or not the movement of the camera is the cause of disconnection in the first wireless communication mode. If the reason for disconnection is the movement of the camera, a control signal is transmitted to the television so as not to execute the process for an avoiding no-signal condition.

This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.

MLD BSS parameters change count at MLD level in management frames

To signal critical updates to Basic Service Set (BSS) Parameters of reported affiliated access points (APs), a reporting AP of the same AP multi-link device (MLD) includes a MLD BSS Parameters Change Count in the ML element of its ML beacon frames. The Count is incremented at each new BSS parameter critical update announced or reported by the reported affiliated APs over time. A non-AP station of a non-AP MLD in ML Power Save mode receives such beacon frame and then directly accesses this information without parsing the complex Reduced Neighbour Report information element. The RNR IE can thus be omitted to save bandwidth. Next, the non-AP station requests the reporting AP for the missing updated BSS parameters of the reported APs, without waking up the reported non-AP stations of the non-AP MLD. The BSS parameters for these reported non-AP stations can then be updated with low complexity.

Systems and methods for extending battery life by monitoring device activity

The disclosed technology includes techniques for preserving battery life of a mobile device by monitoring a mobile device to determine a state of inactivity. A state of inactivity may be determined if the screen of the mobile device is off and the mobile device remains stationary for a period of time. Battery life may be preserved by placing the mobile device and/or a mobile application of the mobile device into an idle state for successive idle periods separated by maintenance periods. When in an idle state, the mobile device and/or a mobile application of the mobile device may be prevented from utilizing various features or functions of the mobile device that may tend to drain the battery. The mobile device and/or mobile application may be granted temporary access to the various features and functions during the maintenance periods to temporarily allow the mobile device and/or mobile application to perform updates

METHOD AND APPARATUS FOR ENERGY-OPTIMIZED DATA TRANSMISSION BY MEANS OF OPC UA PROTOCOL

An OPC UA client that consolidates transmission and reception times so as to extend the antenna amplifier pause times is disclosed. Thus, without requiring a change to the OPC UA protocol, data is sent exclusively at defined focusing times. No sending is meant to be necessary between these times. A set of requests is sent to the server at a particular time. The client then enters reception mode. The server handles the received requests periodically over time. When almost all requests have been handled, a new set of requests is made to the server again. Between these focusing times, the transmitter of the client/mobile device can be switched off completely and hence save power. The method disclosed is totally compatible at all levels of communication, both TCP stack, WLAN for instance. 17.-. (canceled)8. A method of communication in a communication network , between at least one client and at least one server in a client/server system using the OPC-UA communication protocol in which only one server responds to an enquiry from a client , and a keep-alive mechanism terminates a data link between the server and the client if no data packets are transmitted between the server and the client during a keep-alive period , said method comprising:the client sending out a first group of multiple enquiries that follow one another directly in time to the server; andthe server responding to the respective group of multiple enquiries at a time that is offset in time from the time of the respective group of multiple enquires, wherein the period between a first response and a subsequent second response is shorter than the keep-alive period.9. The method of claim 8 , wherein the server apparatus communicates with the client using the Internet.10. The method of claim 8 , wherein the client is on a mobile terminal having a stored-power power supply.11.

Electronic devices for receiving pushed data

Mobile devices such as cellular telephones are provided that communicate with wireless networks. Cellular telephone network equipment may communicate with a cellular telephone over a data connection. The cellular telephone may have an internet protocol (IP) address that allows data to be provided to the cellular telephone over the data connection. To conserve resources and release unused IP addresses, the cellular telephone network equipment may deactivate inactive data connections after a period of inactivity. A baseband processor within a mobile device may periodically send User Datagram Protocol (UDP) keep-alive packets over the data connection to ensure that the data connection remains active. The keep-alive packets may be directed to a packet sink server or may be associated with a black hole route. An applications processor in the telephone may remain in sleep mode during keep-alive packet transmission to conserve power.
