Amit Shah - North Bergen NJ
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04M 1100
US Classification:

455404, 455434, 455450, 455509, 455512, 455515, 370329, 370348
Abstract:

A high priority and/or emergency overload access control system treats a wireless unit as a higher priority wireless unit when the wireless unit is attempting to access a wireless communications system with a high priority call, such as an emergency call. For example, the overload access control system can recognize if the wireless unit is attempting to initiate a call to an emergency number. If so, the wireless unit can perform a persistence test as an emergency class (e. g. overload class ) wireless unit in attempting to access the wireless communications system. Thus, the wireless unit will experience an increased probability of passing the persistence test and thereby reducing the persistence delay in attempting to access the wireless communications system with the emergency call.

Carl Francis Weaver - Hanover Township, Morris County NJ
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04B 106
US Classification:

4552451, 455 24, 455 673, 455 69
Abstract:

A method of controlling the power in a wireless communication system. In one embodiment of the invention, a base station determines the information rate of a signal to be transmitted to a mobile station, and obtains the variable power control scaling factor based on this information rate. The base station then transmits the variable power control scaling factor to the mobile station. The mobile station determines a target signal quality measurement for a received signal from the base station, such as a target E /N , and scales the target E /N by the variable power control scaling factor. The mobile station also obtains an information rate scaling factor based on the information rate of the received signal, and further scales the target E /N by this information rate scaling factor. The mobile station then compares the target E /N to a measured E /N of the received signal. An increase in power of the received signal is requested when the measured E /N of the received signal is smaller than the scaled E /N.

Appl. No.:

09/234414
Inventors:

Ching Yao Huang - Randolph NJ
Frances Jiang - Whippany NJ
Yuen-Yin L. Koo - Morristown NJ
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04Q 700
US Classification:

370329, 370331, 370332, 455436, 455450, 455453, 455452
Abstract:

A method for allocating traffic between multiple carriers in a wireless communications system measures loading on the communication system and selects an appropriate carrier from multiple carriers, based upon the loading measured. A first carrier is selected if the load on the first carrier is lower than or equal to the lowest loading of any supplemental carrier among the multiple carriers. If the load on the first carrier is not lower, then the subscriber may be assigned either to a supplemental carrier or the first carrier. The carrier assignment of the subscriber depends upon a predetermined threshold, which preferably considers actual or estimated differential interference between the first carrier and the supplemental carrier.

Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04B 7216
US Classification:

370335, 370342, 455522
Abstract:

A method for adjusting the power of a probe signal to be transmitted by user equipment to system equipment of a wireless communication system. The power of the probe signal is adjusted based on information received by the user equipment from the system equipment. The information is a local mean of RSSI at the system equipment. The adjusted probe signal is transmitted and thus has an increased likelihood of being detected by the system equipment. Also, the power available for transmitting the probe signal is used more efficiently when the probe signal is adjusted in accordance with the local mean information received by the user equipment from system equipment of the wireless communication system.

US Patent:

6925057, Aug 2, 2005
Filed:

Dec 6, 2000
Appl. No.:

09/731213
Inventors:

Terry Si-Fong Cheng - Singapore, SG
Frances Jiang - Whippany NJ, US
Stanley Vitebsky - Parsippany NJ, US
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

G01R031/08
US Classification:

370235, 370333, 370253, 4554522, 455512
Abstract:

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. The end user that has the greatest final result is normally selected to next receive data.

US Patent:

6999425, Feb 14, 2006
Filed:

Dec 7, 2000
Appl. No.:

09/732454
Inventors:

Terry Si-Fong Cheng - Singapore, SG
Frances Jiang - Whippany NJ, US
Stanley Vitebsky - Parsippany NJ, US
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04Q 7/00
H04J 3/22
US Classification:

370252, 370278, 370329
Abstract:

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. This aggregate rate of data during the frame is filtered to minimize irregularities by using the moving average of an infinite impulse response filter and then normalized.

Abstract:

A wireless data network distinguishes among different users connected to the network and associates each user with a service class that offers a selected level of service. The base station in the network queries the user for its unique user identification code and accesses a database linking user identification codes with their corresponding services classes. The network then controls the service level given to that user based on the service class associated with the user identification code. The user identification code can be sent to the network via existing fields in current standards.
