摘要:
A system and method for the distribution of time signals is available for devices with multiple communication cores. An embodiment may or may not use a centralized manager for the management of time preservation. When a communication core in a multiple communication core device requires timing information, it may request the time information from another communication core or from the centralized manager. The centralized manager, if present, can obtain time information from an external source or from one of the communication cores. The result can be reduced power consumption at a lower cost.

Some demonstrative embodiments include devices, systems and/or methods of location estimation of a mobile device. For example, a device may include a location error corrector to provide location data to at least one application executed by the device, the location data indicating an estimated location of the device, which is based on location information from at least one location-information generator; to receive from the application error feedback information indicating an error in the estimated location; to determine a correction based on the error feedback information; and to provide to the application corrected location data based on the correction.

Sonic demonstrative embodiments include devices, systems and/or methods of collaboratively correct location errors. For example, a device may include a collaborative location error corrector to collaboratively correct location errors for at least one group of two or more wireless communication devices, the location error corrector is to receive from at least a first wireless communication device of the group an error report indicating an error in an estimated location of the first wireless communication device, to determine correction information based at least on the error report from the first wireless communication device, and to provide the correction information to at least a second wireless communication device of the group.

Some demonstrative embodiments include devices, systems and/or methods of estimating a location of a mobile device. For example, a location estimation entity (LE) may be configured to receive from a server location-based location-enabling source (LES) information identifying one or more location-enabling sources based on a location area of a mobile device, and to communicate with the one or more identified location-enabling sources information for estimating the location of the mobile device.
摘要:
A method and system for time synchronization in a mobile device are disclosed. The method includes negotiating a synchronization schedule. The synchronization schedule defines a plurality of synchronization times for receiving synchronization messages. The method further includes transitioning the mobile device from a first state to a second state to receive a synchronization message. The mobile device uses less power in the first state than the second state and the mobile device cannot receive the synchronization message when in the first state. The method further includes synchronizing a clock component in response to receiving the synchronization message.
摘要:
Disclosed in some examples are methods, systems, and machine readable mediums that provide location based services such as navigation in an indoor space by utilizing a network of specially configured locator nodes (LNs) and the identified line of sight (LOS) relationships between the LNs. The LOS relationships may be automatically learned by the LNs.
摘要:
A method that provides a solution to the problem of overlapping branches in a point to multipoint call. The method is suitable for both Leaf Initiated Joins (LIJ) and existing point to multipoint call. The method has applications when adding a new leaf to an already existing point to multipoint connection and where the ROOT node has a corrupted point to multipoint view of the network. The method includes the overlapping node realizing that it is an overlapping node whereby it continues with the establishment of the downstream path in a conventional manner. The overlapping node then waits for the SETUP/ADD PARTY CONNECT to be received before continuing. Once the CONNECT is received, the overlapping node establishes an end point reference path to the point to multipoint root node over existing branches. The new call segments are established and the overlapping segments are then trimmed from the tree.
