摘要:
A communication system (100) includes a shared communication medium, such as a communication channel or a base station, for providing messages and transmission devices (110) for transmitting the messages over the shared communication medium during sharing periods defined by a sharing pattern (114). A trading center (105) coupled to the transmission devices (110) modifies the sharing pattern (114) in response to traffic handled by the transmission devices (110).

Traffic in a radio communication system (FIG. 1) is adaptively balanced (300) to control congestion. A congestion model is maintained (302) with congestion dependencies including first and second types of congestion along with corresponding likelihood functions that indicate a likelihood that the first type of congestion will lead to the second type of congestion. An early warning of an impending congestion is detected (304) from an incoming traffic mix which exceeds an output traffic capability, given a current output allocation and configuration. The congestion model is accessed (306), in response to detecting the impending congestion, to identify and determine a priority for possible sources of the impending congestion. Action is then taken (308, 314, 318) to relieve the impending congestion by doing at least one of (a) increasing output resources and (b) decreasing traffic rates from the possible sources, prioritized in accordance with the congestion model.

A battery saving interval utilized for communicating with a portable subscriber unit (122) in a radio communication system is dynamically adjusted. An occurrence of a predetermined triggering event associated with the portable subscriber unit is observed (504), and the battery saving interval utilized for communicating with the portable subscriber unit is adjusted (506) in response to the predetermined triggering event, while battery saving intervals of other portable subscriber units in the system are left unchanged.

A stochastic method and apparatus schedules airtime in a radio communication system having a plurality of transmission protocols. At a queue measurement time airtimes are measured (402) that are required for transmitting messages stored in queues (222) corresponding to the plurality of transmission protocols. A corresponding plurality of estimated arrival rates are determined (404) equal to estimated rates of increase of the plurality of airtimes due to arriving traffic. An objective function is structured (408) equal to a sum of penalties corresponding to the plurality of transmission protocols, the penalties dependent upon the plurality of airtimes and the plurality of estimated arrival rates, and further dependent upon an optimal airtime allocation decision. The optimal airtime allocation decision is derived (410) by minimizing the objective function, and then airtime is allocated (412) among the plurality of transmission protocols in accordance with the optimal airtime allocation decision.
摘要:
A method and apparatus utilize an original stream (424) for communicating. Additional data is selected from predetermined messages to define a selected message (422). The original stream is altered (604) in a manner corresponding uniquely with the selected message to form a transmission stream (522) having a size identical to that of the original stream, and the transmission stream is then communicated (606, 608). The alteration of the stream is reversed (612) as it applies to the predetermined messages, thereby generating candidate streams. An error tally (544) corresponding to each of the candidate streams is determined (614) from an error checking mechanism (310, 312). From the candidate streams a member is selected corresponding to a lowest error tally, the member thereafter defined (620) to be a restored original stream. One of the predetermined messages is selected (622) as the selected message associated with the lowest error tally.
摘要:
Channels are assigned to a plurality of transmitters (206) in a radio communication system. First, interference constraints are defined (402) for the plurality of transmitters, and channel capacity required to handle traffic for each of the plurality of transmitters is measured (404). Then a mathematical programming technique is applied (406) to minimize the total number of channels assigned in the system, consistent with the interference constraints and the channel capacity required. The programming technique is selected from an integer programming technique (414) and a linear programming technique (408).
摘要:
A method and apparatus for providing a wireless transmit/receive unit (WTRU) with access to at least one peripheral device, and/or at least one peripheral device associated with an available auxiliary device. The current peripheral device requirements of the WTRU are determined. The radio frequency (RF) environment of the WTRU is scanned to determine if there are any available wireless peripheral devices or wireless auxiliary devices proximate to the WTRU. A determination is also made as to whether there is a wired peripheral device or a wired auxiliary device available. A list of currently available peripheral devices is compiled by scanning at least one peripheral device registry associated with at least one of a wireless auxiliary device and a wired auxiliary device. The list is presented on the WTRU's display and a user selects at least one of the available peripheral devices from the list.

An electronic device receives user inputs. The user inputs indicating interactions of the user with processing of the electronic device. The device determines interaction patterns of the user with the device. The device uses the determined interaction patterns to determine adjustments for the electronic device. The electronic device is adjusted using the determined adjustments.

A messaging device for receiving a plurality of messages that have a relevancy status includes a selective call receiver (22) for receiving the plurality of messages, the relevancy status, and updates to the relevancy status, a memory (30) for storing at least a portion of the plurality of messages and the updates to the relevancy status and a processor (24, 40 and 28) for processing the portion of the plurality of messages that have received updates to the relevancy status. The relevancy status is ideally a location identifier and could additionally include a valid time indication.
