Embodiment Construction

[0036]The techniques described in this application can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier FDMA (SC-FDMA) and other systems. The terms "system" and "network" are often used interchangeably. A CDMA system may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, and so on. UTRA includes Wideband-CDMA (W-CDMA) and other variants of CDMA. CDMA2000 covers the Interim Standard (IS)-2000, IS-95 and IS-856 standards. A TDMA system can implement a radio technology such as Global System for Mobile Communications (GSM). OFDMA systems can implement radio technologies such as Evolved Universal Terrestrial Radio Access (Evolved UTRA or E-UTRA), Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi)...

Abstract

As a communication is engaged upon a mobile device, data can be relayed through a base station. Determining which base station the mobile device should use can be based upon location and velocity of the mobile device. Other factors can be taken into account in determining a base station, such as power output of the mobile device and base station, load balancing, mobile device trends, and the like. Based upon these various factors, a determination can be made if the mobile device should transfer base stations.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Application Serial No. 61 / 016,759, filed December 26, 2007, entitled "Location Assisted Handofin LTE," which is hereby incorporated by reference in its entirety. technical field [0003] The following description relates generally to wireless communications and, in particular, to managing communication handoffs, typically in conjunction with mobile devices. Background technique [0004] In order to provide various communication contents such as voice, data, and the like, wireless communication systems are widely deployed. A typical wireless communication system may be a multiple access system, which supports multiple users to communicate by sharing available system resources (eg, bandwidth, transmission power...). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA...
