Abstract: Motion-based handoff control techniques are disclosed. For example, an apparatus may include a signal strength determination module, a motion determination module, and a handoff controller. The signal strength determination module generates signal strength information corresponding to the strength of a wireless signal received from a first wireless link. From this information, the motion determination module determines a motion characteristic of the apparatus. Based on the motion characteristic, the handoff controller performs handoff operations for a second wireless link. In this manner, handoff operations may be tailored to the operational characteristics of the apparatus. For instance, certain handoff operations may be halted when the motion characteristic indicates the apparatus having a substantially stationary position. Other embodiments are described and claimed.

Abstract: Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

Abstract: Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

Abstract: According to the embodiments of the techniques of this application, a wireless data device or other data node sends solicitation messages periodically to a wireless gateway, such as a PDSN, when there is no data traffic between the wireless data device and a wireless data network. Each solicitation message resets the simple IP inactivity timer on the wireless gateway. When multiple wireless data devices send solicitation messages, the interval between subsequent transmissions of solicitation messages is randomized to reduce the probability of collision with the solicitations from other devices on the same wireless link. The solicitation timer, for instance, may be based on the simple IP inactivity timer setting on the wireless network, and the number of wireless data devices that the wireless data network serves. Expiration of the solicitation timer at the wireless data device or other data node causes the next solicitation message to be sent from or on behalf of the wireless data device.
