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.

International Classification:

H04Q 720

US Classification:

455434, 455450, 455515

Abstract:

The present invention, in illustrative embodiments, implements systems and methods for adjusting the timing of access requests in mobile communications systems, such as IS-95-A mobile telephone systems, to reduce the likelihood of request collisionsâespecially during periods of very high calling rates. These embodiments employ measurements of access channel occupancy, as well as system operator inputs, to develop thresholds and parameter translations at a base station. Execution of control algorithms at a base station advantageously yields modified persistence test parameters sent to mobile stations. When overload conditions are present, these modified parameters cause the mobile stations to experience variable delays through judicious control of persistence testing at the mobile stations.

International Classification:

H04Q 700

US Classification:

370332, 370436, 370441, 370462

Abstract:

A method and apparatus for transmitting a burst of data over a supplemental channel on just one leg of a handoff by changing the maximum allowed burst duration of the data to be transmitted over the supplemental channel as a function of the future and/or current characteristics of the communication link of the leg(s) of the handoff. The data is then transmitted over just one leg of handoff using the maximum allowed burst duration. By changing the parameters of the data, the data may still be acceptably received at the mobile terminal over just one leg of the soft handoff even when the strength of the pilot signal used for the supplemental channel changes significantly. In an illustrative embodiment of the invention the stability of the communication link is used as a way of ascertaining the future conditions of the communications link.

Appl. No.:

Inventors:

Qi Bl - Morris Plains NJ, US
Ching Yao Huang - Randolph NJ, US

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04Q007/20

US Classification:

4554522, 455450

Abstract:

A communication system includes a base station and a plurality of remote stations wirelessly communicating with the base station. The base station determines a respective RF quality for each remote station. In response to a request for RF resources from a given remote station, the base station determines whether admission of the given remote station would exceed an RF power budget threshold. If the RF power budget threshold would not be exceeded, the RF quality is compared to a first quality threshold to determine whether to allocate the requested RF resource to the given remote station. Otherwise, the RF quality is compared to a second quality threshold more stringent than the first quality threshold to determine whether to allocate the RF resource to the given remote station. The base station may further determine whether to allocate requested RF resources on the basis of a priority of the requested resources.

International Classification:

US Classification:

370232, 370235, 3703954, 4554521, 4554522, 455453

Abstract:

In the method, an average user throughout over all active users is computed, and each user's user perceived throughput is compared against the computed average throughout. Based on the comparison, the scheduling of the plurality of users is prioritized. In an embodiment, a priority adjustment factor is applied to each user to prioritize the scheduling of users to receive a data transmission. The priority adjustment factor is determined based in part on an update function. The update function is proportional to a calculated difference between each user's user perceived throughput and the average user throughput. Based on the sign of the update function, the priority adjustment factor is either incremented or decremented, and hence, prioritization of users is ordered. The output of the scheduler is user identifying information that informs the base station to transmit data in a current time slot to the identified user determined as the highest priority user by the scheduling method.

US Classification:

3405721, 3405731

Abstract:

A system consists of remote identification tag (in the form of wristband) for personnel who must undergo hand hygiene frequently during a day's work, programmed soap and rinse-free disinfectant dispensers, entry-exit sensors for controlled access areas and data transfer stations is used to monitor and record every handwashing procedure along with its thoroughness as well as every hand cleaning event with rinse-free disinfectant. The system will further prompt each worker's identification tag at an appropriate place to examine its record to see whether a hand hygiene procedure is required before proceeding to his/her next task. The recorded data with time-date of each event will be transferred to a central computer for statistical analysis and presentation as a daily and/or periodic hand hygiene compliance report on each staff, department, shift and the entire institution.
