Abstract

Abstract Fast resource assignments, especially needed in microcellular network architectures having many fast moving subscribers (e.g.42) and high traffic volume, is provided through the use of a priority based resource assignment apparatus and procedure. Part of the communications resources in a cellular network, for example, one carrier frequency and/or one time slot, or particular code division multiple access sequences, are dedicated to the execution of the assignment procedure. Available communications resources are auctioned to cellular subscribers (42) contending for resources (e.g.,in 32) based upon a level of priority assigned to each contending subscriber. The priority level may be based on such things as the quality of service to which a customer subscribes or the particular needs of a subscriber at the time the subscriber is contending for resources, for example, the subscriber's request for resources may be prompted by a need to make a handoff (from 32 to elsewhere). The procedure involves an auction period when a determination is made regarding which of a group of contending subscribers has the highest priority level. The procedure then enters a resource assignment period where an available communications resource is actually assigned to the subscriber having the highest priority level. The auction and assignment periods are then repeated for the remaining contending subscribers until there are no longer any contending subscribers or there are no longer any available resources. Fast resource assignment could be used to increase system capacity and efficiency of spectrum utilization through the ability to perform speech activity resource sharing.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 56 words
An apparatus for assigning one of a plurality of communications resources in a wireless telecommunication system to a requesting subscriber, comprising: means for identifying one of a plurality of prioritized subscribers contending for service on the wireless telecommunications system having the highest level priority; and means for assigning an available communications resource to the identified subscriber.
Claim 2
Dependent Claim 40 words
The apparatus of claim 1, in which the identifying means comprises a means responsive to a modulated assignment carrier frequency for performing an auction procedure with respect to one or more contending subscribers which determines the highest level priority subscriber.
Claim 3
Dependent Claim 30 words
The apparatus of claim 2, in which the identifying means further comprises a means for repeating the auction procedure for subscribers remaining after identification of the highest level priority subscriber.
Claim 4
Dependent Claim 24 words
The apparatus of claim 2, in which the modulated assignment carrier frequency is modulated in accordance with an M-ary frequency shift keying modulation procedure.
Claim 5
Dependent Claim 21 words
The apparatus of claim 4, in which the frequency shift keying modulation procedure is a quaternary frequency shift keying modulation procedure.
Claim 6
Dependent Claim 18 words
The apparatus of claim 2, in which the assignment carrier is modulated in accordance with a CDMA procedure.
Claim 7
Dependent Claim 32 words
The apparatus of claim 2, in which the assigning means assigns an available communications resource to the subscriber having the highest level priority in response to the completion of the auction procedure.
Claim 8
Dependent Claim 39 words
The apparatus of claim 1, in which the identifying means is responsive to a multidigit code comprising a predetermined number of digits uniquely identifying each subscriber and a priority code identifying a level of priority associated with each subscriber.
Claim 9
Dependent Claim 38 words
The apparatus of claim 8, in which the identifying means is responsive to the most significant digits of the priority codes of a plurality of contending subscribers for determining which of the most significant digits is the highest.
Claim 10
Dependent Claim 57 words
The apparatus of claim 9, in which the identifying means further comprises a means for notifying the contending subscribers of the magnitude of the highest most significant digit of the contending subscribers and inhibiting further communication between the identifying means and those contending subscribers having most significant digits with a magnitude less than the highest received magnitude.
Claim 11
Dependent Claim 43 words
The apparatus of claim 10, in which the identifying means repeats the auction procedure for the next most significant digits of the contending subscriber which had the highest magnitude most significant digits until only one contending subscriber having the highest priority code remains.
Claim 12
Dependent Claim 34 words
The apparatus of claim 11, in which the assigning means is responsive to the idenfication of the contending subscriber with the highest magnitude priority code and assigns an available communications resource to that subscriber.
Claim 13
Dependent Claim 45 words
The apparatus of claim 12, in which the assigning means transmits to the subscriber having the highest magnitude priority code a multidigit code representing the identity of a communications resource which is to be used by that subscriber to communicate with the wireless telecommunications system.
Claim 14
Dependent Claim 41 words
The apparatus of claim 13, in which the identifying means comprises a means for repeating the procedure for identifying a contending subscriber with the highest magnitude priority code in response to the assignment of a communications resource by the assigning means.
Claim 15
Dependent Claim 27 words
The apparatus of claim 14, in which the assigning means assigns another communications resource to a subscriber having the highest priority code of the remaining contending subscribers.
Claim 16
Dependent Claim 22 words
The apparatus of claim 1, in which the communications resource is a time slot on one of a plurality of carrier frequencies.
Claim 17
Dependent Claim 14 words
The apparatus of claim 1, in which the communications resource is a CDMA sequence.
Claim 18
Dependent Claim 45 words
The apparatus of claim 1, in which at least one of the assigning and identifying means comprises means for spreading signal power produced by the identifying means or the assigning means over at least a portion of a bandwidth allocated to the wireless telecommunications system.
