US Patent:

20090163206, Jun 25, 2009

Filed:

Dec 19, 2007

Appl. No.:

11/960106

Inventors:

Ravi M. Adatrao - West Dundee IL, US
Tommy Chang - Niles IL, US
Pramod Karnam - Rolling Meadows IL, US
Apurv Mathur - Wheeling IL, US
Robert S. Nikides - Carol Stream IL, US

Assignee:

MOTOROLA, INC. - Schaumburg IL

International Classification:

H04Q 7/20

US Classification:

455436

Abstract:

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.

Assignee:

MOTOROLA, INC. - Schaumburg IL

International Classification:

H04J 3/14

US Classification:

370237

Abstract:

A method includes receiving a request from a mobile station () to initiate a call session with a base station (). After receiving the request, the base station determines that it cannot process the call session with the mobile station because the base station is fully loaded and sends a busy indication to the mobile station in response to determining that it cannot process the call session. The method can also include sending a scan response to the mobile station indicating a load for a neighboring base station () to the base station and handing over the mobile station to the neighboring base station.

International Classification:

H04W 76/02
H04W 28/12
H04W 28/08
H04W 84/04

Abstract:

In a communication system where a primary cell is controlled by a first base station and a secondary cell is controlled by a second, different base station, flow control is performed between the primary cell and the secondary cell for data for a radio link control layer. According to the flow control, the data for the radio link control layer is communicated between the first and second base stations using a link between the first and second base stations. Flow control may be performed between the primary cell and the secondary cell by dynamically controlling a depth of queued radio link control data in the secondary cell for one or more UEs based on one or more factors, e.g., current/future loading of secondary cell, peak theoretical throughput for a UE in the secondary cell, and/or a UE's current channel quality information. Apparatus, methods, and computer program products are disclosed.
