A method, information processing system, and wireless communication system, initiate a handover scanning procedure with a wireless device. The method includes monitoring a first signal strength measurement () transmitted by a wireless device (). A second signal strength measurement associated with the wireless device () that is measured locally is monitored (). The method also includes determining, in response to monitoring the first signal strength and the second signal strength measurement, if a scan event trigger has been detected (). A scan initiation message is transmitted () to the wireless device () in response to a scan event trigger being detected. The scan initiation message signals the wireless device () to perform handover scanning procedures.

Network initiated proactive handover procedure for fast moving wireless devices

A method, a network base station, and a user communication device for transmitting control data are disclosed. A processormay encode a rescue frameof a set of frames with a higher rescue overhead to data ratio. The processormay encode an ancillary frameof the set of frames with a lower rescue overhead to data ratio. A transceivermay transmit the set of frames.

Method for efficiently increasing hand-off and access reliability

A method and a system for switching a mobile device () from a source Base Transceiver Station (BTS) to a target BTS in a mobile network () are disclosed. The method includes detecting an intention to switch the cell transmitted by the mobile device. A Base Station Controller (BSC) () then receives the switch detect time from the source BTS and/or the target BTS. The switch detect time is processed by the BSC to determine the switch time for the mobile device. The mobile device then switches from communication with the source BTS to communication with the target BTS, based on the switch time.

Method and system for switching a mobile device in a mobile network

A communication system includes a forward link from a base station to multiple mobile units, the forward link having multiple shared channels (SHCH's), multiple shared control channels (SHCCH's), and multiple dedicated pointer control channels (DPTRCH's), and utilizes HARQ error control for error detection and error correction. The mobile unit, when listening to the DPTRCH, uses a SHCCH pointed to by the DPTRCH to demodulate and decode data on the SHCH. Throughput problems may arise in the system when the mobile unit combines and decodes the wrong SHCH data, that is, SHCH data that is intended for a different mobile unit, or may incorrectly decodes SHCH data that is intended for the mobile unit. In order to improve the data throughput of the system, the systems employs a flush test and an energy detector test to prevent improperly decoded data blocks from corrupting properly decoded data blocks.

Method and apparatus for preventing received data from corrupting previously processed data in a wireless communications system

A mobile station ( ) selects ( ) a preferred cell site for transmitting a frame of data to be sent subsequently to the mobile station. A base station ( ) of the preferred cell site schedules ( ) a transmission of the frame of data, wherein parameters for the transmission are determined by the base station from recently-measured channel and interference information. Thereafter, the base station sends ( ) the frame of data from the preferred cell site; and an active set of base stations associated with the mobile station at ones of a plurality of cell sites synchronize ( ) their data queues to reflect the transmission of the frame of data.

Method and apparatus for providing a distributed architecture digital wireless communication system

A method is provided for preemptively protecting mobile units within a wireless communication system from interference caused by sudden high speed data transmission within the system. The method includes detecting an imminent high speed data transmission in at least one particular cell of the system. At least each current local mobile unit is identified that is in signal communication with a base station of the at least one particular cell. A current operating level for at least each of the current local mobile units is determined. A necessary increase in the current operating level is estimated for at least each of the current local mobile units. A transmit time is predicted for when the imminent high speed data transmission will occur. The current operating level for at least each of the current local mobile units is increased by the corresponding necessary operating level increase at a time no later than the predicted transmit time.

Preemptive power-up method for protecting system users from sudden high speed data

An estimated signal quality measurement (224) of a received signal is determined by sampling a first signal quality measurement (208) at a first time and sampling a second signal quality measurement (203) at a second time. The second signal quality measurement being sampled from a different source than the first signal quality measurement. A predicted signal quality value is then calculated at a third time based on the first and second received signal quality measurements. Next, a signal quality value of a signal received at the third time is measured. The predicted signal quality value and the measured signal quality value are then used to estimate a signal quality measurement (224) of the received signals (203, 208).
