Patent number: 8874172Abstract: A wireless communication system (20) includes an ability to discern whether an end of a communication link between a mobile station (22) and a base station (26) corresponds to the mobile station (22) tuning away from a first service to a second, different service. In a disclosed example, a radio network controller (28) includes a link monitoring portion that uses information regarding the mobile station from the second service to determine a pattern of expected tune aways by the mobile station to the second service. In one disclosed example, the link monitoring portion uses observed mobile station behavior to estimate the pattern of expected tune aways. Whenever an end of a communication link with the mobile station corresponds to an expected tune away, that end is not considered for purposes of service measurement parameters.Type: GrantFiled: September 29, 2005Date of Patent: October 28, 2014Assignee: Alcatel LucentInventors: Frances Jiang, Vladan Jovanovic, Yang Yang

Patent number: 8730923Abstract: A resource allocation algorithm identifies a resource hogger in a wireless communication system data sharing arrangement and control shared resource overuse by the resource hogger. In one embodiment, the base station for a given sector in the system tracks the time-slot usage of each active user in the sector. If the usage for any user reaches a predetermined hogger threshold, normal target QoS enforcement is suspended for that user to allow more time slots to be allocated to the other, non-hogger users. When the resource hogger user's usage falls below the threshold, target QoS enforcement is returned to that user. Temporarily suspending target QoS enforcement for resource hoggers and allocating the remaining resources to other users prevents resource hoggers from deteriorating performance of the entire system.Type: GrantFiled: June 11, 2003Date of Patent: May 20, 2014Assignee: Alcatel LucentInventors: Daniel Matthew Andrews, Qi Bi, Frances Jiang, Aleksandr Stolyar, Yang Yang

Patent number: 7706311Abstract: The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.Type: GrantFiled: December 9, 2005Date of Patent: April 27, 2010Assignee: Alcatel-Lucent USA Inc.Inventors: Qi Bi, Terry Si-Fong Cheng, Frances Jiang, Yang Yang

Patent number: 7565152Abstract: A method of wireless communication over the reverse link. The method may include evaluating a reverse link loading. This evaluation step may involve examining at least two resources associated with reverse link loading within a first time period. Thereafter, a message is broadcast containing information regarding the availability of resources. This message is generated in response to the evaluated reverse link loading. This availability of resources message may correspond with an overload condition, increasing a number of active connections, decreasing the number of active connections, increasing an available transmit rate, maintaining the available transmit rate and/or decreasing the available transmit rate. In one example, the availability of resources message comprises a reverse activity bit.Type: GrantFiled: July 31, 2003Date of Patent: July 21, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Asif D Gandhi, Frances Jiang, Mathew Thomas, Stanley Vitebsky

Patent number: 6999425Abstract: A method for determining the reverse link data Rate Limit for mobile stations active on the reverse link of a High Data Rate system is disclosed. In the ideal case, the Rate Limit is based on only the number of mobile stations located in a common sector that are actually active on the reverse link. Currently, the Rate Limit is determined from the total number of mobile stations in a common sector where the total includes mobiles that are transmitting and receiving. Thus, the current method includes mobile stations that are active on the forward link and may not be active on the reverse link. In this invention, a more optimum method of estimating the reverse link loading is obtained from calculations which includes only the mobile stations which are active on the reverse link. An estimate of the reverse link loading of the mobile stations in a common cell is obtained by adding together the data rates of the data sent from each mobile in a common sector during a common frame.Type: GrantFiled: December 7, 2000Date of Patent: February 14, 2006Assignee: Lucent Technologies Inc.Inventors: Terry Si-Fong Cheng, Frances Jiang, Stanley Vitebsky

Patent number: 6925057Abstract: The present invention is a method for selectively providing, on demand, a Quality of Service level to an end user's data transmitted from a base station to a mobile station of a High Data Rate system. In the disclosed method, a data base is established which contains the Quality of Service level selected by a mobile user from a plurality of levels for data to be transmitted from the base station to the mobile station. Using the reverse link, an end user at a mobile notifies the base station that it is ready to receive data and specifies the rate at which the data is to be sent. Upon receipt of the request for data from the mobile terminal, the base station accesses and runs a scheduler which determines which user's data is to be transmitted next. For each end user, the scheduler divides the requested data rate by the average rate of data received by the mobile during a specific interval and then combines by adding or multiplying the result with the Quality of Service level requested by the end user for data.Type: GrantFiled: December 6, 2000Date of Patent: August 2, 2005Assignee: Lucent Technologies Inc.Inventors: Terry Si-Fong Cheng, Frances Jiang, Stanley Vitebsky

Publication number: 20050096059Abstract: A method of wireless communication. The method includes the step of transmitting at least one message including delay information. This delay information may correspond with a delay length associated with accessing a service through an open loop network. The delay length may include a time interval between a first instant corresponding with a received service request and a second instant corresponding with granting service access. Alternatively, the delay length may comprise a time interval between a first instant corresponding with a received service request generating at a predefined moment in time and a second instant corresponding with granting service access. The delay length may correspond with traffic congestion, channel condition, system loading, processor occupancy, queuing delay, and/or scheduling delay, for example.Type: ApplicationFiled: October 31, 2003Publication date: May 5, 2005Inventors: Frances Jiang, Gopal Kumar, Aparajita Misra, Ganapathy Sundaram

Publication number: 20050041673Abstract: A resource allocation method equalizes distribution of network resources among gateway users connected to at least one gateway access terminal and non-gateway users. Gateway access terminals having data backlogs exceeding a predetermined backlog threshold are assigned higher priorities to increase their transmission rate and relieve the backlog. Alternatively, priority is assigned based on the relative data backlogs of all of the gateway access terminals in the network. This ensures that gateway users are allocated resources fairly and in a comparable manner to non-gateway users, maximizing system throughput.Type: ApplicationFiled: August 20, 2003Publication date: February 24, 2005Inventors: Frances Jiang, Yang Yang
