Abstract: Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.

Abstract: Methods and systems are provided for overload control in a wireless communication system. An overload control mechanism identifies an instance of use to eliminate from among a plurality of instances of use in a wireless coverage area. In an overload situation, the overload control mechanism may, for each instance of use, determine a respective ratio of the value of instance of use to the quantity of resource consumed by the instance of use.

The overload control mechanism may select as many instances of use as possible, such that the total amount of resources consumed by the selected instances of use is as high as possible without exceeding the threshold load, and then the overload control mechanism may eliminate the remaining instances of use.

Abstract: A multi-modal wireless communication device contains multiple radios for communication with wireless networks utilizing different communication protocols. When a communication link with a first base station using a first communication protocol is broken, and a communication link established with a second base station, the mobile device stores the communication data related to the prior communication link and stores it in association with the current communication link. At some future time, the mobile device may establish a communication link with the second base station. The mobile device can check the stored data to see if there is a an alternative network connection in the proximity of the current connection. If so, the mobile device may activate the radio for communication with first base station and actively attempt to establish a communication link based on the proximity data recalled from storage in the mobile device.

Abstract: A method and system for protecting a LNA by acquiring a radio frequency control channel signal at a tower top low noise amplifier (TTLNA) system. In response to acquiring the radio frequency control channel signal, LNA mode information is determined from the acquired radio frequency control channel signal. Based at least in part on the determination, the TTLNA is configured to either receive mode when the LNA mode information indicates receive mode or transmit mode when the LNA mode information indicates transmits mode. In an exemplary embodiment, the TTLNA is configured to receive mode only after a determination is made that there is no transmit energy present on the feedline connecting the BTS and the antenna. In another exemplary embodiment, the TTLNA is initialized in transmit mode.

Abstract: A data transfer system receives a first service flow, a second service flow, and a third service flow that comprise a data session for a user device. The data transfer system transfers the first service flow to a scheduler using a first data rate limit and transfers the second service flow to the scheduler using a second data rate limit. The data transfer system also transfers the third service flow to the scheduler. The scheduler schedules transfers of the first service flow and the second service flow at a higher priority than transfers of the third service flow. The data transfer system transfers the first service flow, the second service flow, and the third service based on the prioritized schedule and using a third data rate limit. Thus, the first and second service flows receive a limited amount of preferential bandwidth, and the third service flow obtains unused bandwidth from the first and second service flows, subject to the third data rate limit.

Abstract: A method of operating a communication system is disclosed. A first communication session between a first base station and a mobile station is established. A service session between a first access network and the mobile station is established. When the mobile station moves to the service area of a new base station, a second communication session between a second base station and the mobile station is established. A distance between the first base station and the second base station is determined. If the distance exceeds a criteria, the service session is handed off a second access network. The criteria, which must be greater than zero, corresponds to the number of base station service areas separating the first base station and the second base station.

Abstract: Methods and systems are provided for using base-station location to assist mobile-device system acquisition. A mobile station, which stores a network identifier, selects a carrier frequency. The mobile station receives, from a base station on a first carrier frequency, geographic coordinates of the base station and a base-station network identifier, and determines whether the base-station network identifier matches the mobile-station network identifier. If the base-station network identifier matches the mobile-station network identifier, the mobile station will scan the indicated home frequency bands and will connect to one of the home frequencies, and if the base-station network identifier does not match the mobile-station network identifier, the geographic coordinates of the base station are used to identify a market area and a most-preferred carrier frequency is selected from the identified market area.
