摘要： A system for providing statistical multiplexing of speech, other real-time data services and non-real-time data services for point to point and point to multipoint communications. The system has fast access and assignment procedures that allow the multiplexing of real-time, delay-critical data services with non-real-time data services. Continuity of periodic control channels across speech talkspurt and silence periods for conversational voice is maintained to carry signal measurement reports, channel quality feedback, and “comfort” noise information between different parts of the system.

摘要： Unlike earlier methods and systems in which Radio Link Control (RLC) performance was characterized in terms of the throughput, and the size of the higher layer Protocol Data Units (PDUs) or packets to be transferred was ignored, a method and apparatus is provided that is based on the delay of a higher layer PDU or packet. A method and apparatus so based have less delay than a method and apparatus based on employing adaptive coding and modulation to achieve the greatest mean throughput of a data block.

摘要： A system and method for providing wireless time division multiplexed communications in which time is divided into a plurality of frames and each frame is divided into N data bursts, which has a first multiplexer defining a channel as a series of bursts that occur periodically every N bursts once per frame; a second multiplexer defining a sub-channel as every Mth burst of said channel; and a transmitter transmitting said channel and sub-channel from a first station to a second station. A new interleaving 0246/1357 method is used by the system which is just as good as the known 0123/4567 method when ideal frequency hopping is used, and 0246/1357 has better performance when non-ideal frequency hopping or no frequency hopping is used.

摘要： Four stages of digital cellular architecture are presented which reuse much of the existing voice infrastructure while allowing graceful introduction of data and integrated voice/data services over industry standard, low cost platforms. First, a separate ATM-based infrastructure is introduced that supports data services. A new data call control is introduced on industry standard hardware platforms using object oriented and modular programming. Second, ATM is introduced at radio ports and call control functions are migrated to the new ATM-based call control platforms. Third, vocoders are introduced at the DCS. Fourth, the cellular functions of the legacy cellular switch are phased out and replaced by the ATM-based target architecture.

摘要： A code division multiple access system method and apparatus provides for allocation of increased bandwidth to a requesting mobile station. An access controller receives a data burst request (from either a requesting mobile station or from an external network already in connection with the mobile station) requesting a first data rate in excess of the basic data rate B allocated to a mobile station of a first cell. The access controller determines an increased data rate which is to be granted to said mobile station without causing excessive interference at said first cell and at least one adjacent cell and transmits a data burst assignment to a base station of said first cell indicating the increased data rate which has been granted to said mobile station. In another feature, the access controller processes a data burst request received from a mobile station involved in a soft handoff between multiple base stations and negotiates with those base stations for an increased data rate which may be granted to the requesting mobile station. One feature enables additional interactions to further refine the allocation process. A variety of system architectures are also described.

摘要： Methods and apparatuses for allocating control and data time slots to a plurality of wireless mobile stations in a wireless communication system using time division multiplexing. The methods and apparatuses assign such time slots by first placing the wireless mobile stations into a number of different groups. Then, control time slots and anchor data time slots are assigned to the groups in the uplink and downlink frames of a carrier such that the uplink control time slot for each group is maximally spaced in time relative to the downlink control time slot for the same group. Data time slots are subsequently assigned to a particular mobile station by assigning time slots in the uplink and downlink frames which are as close as possible to the group's uplink or downlink anchor data time slots, as the case may be, according to a “grow from center” technique.

摘要： A method and system for reducing delay in wireless communications by use of a burst based access and assignment system. The method for setting up a communication channel uses short burst(s) (essentially a slot of a time frame). Time is saved by keeping the uplink and downlink channels flexible and independent of each other. Thus less time is used trying to fit all requests and responses into constrained choices as in previous protocols. The result is less delay to the mobile user and greater usage density for the wireless service provider.
