摘要： Each of a plurality of wireless communication units (102) is pre-programmed (402) with a plurality of orthogonal codes corresponding to a plurality of canned messages, the plurality of orthogonal codes chosen such that when a group of different canned messages are received simultaneously by a wireless processing device (104), thereby producing an interference symbol pattern, the interference symbol pattern provides a non-zero probability of correctly decoding at least some of the group. A portion of the plurality of wireless communication units then detects (404) a triggering event. Each of the portion selects (406) one of the plurality of canned messages as a selected message to be transmitted in response to the triggering event, and transmits (408) one of the plurality of orthogonal codes corresponding to the selected message during a randomly-selected slotted-aloha time slot.

摘要： Method and apparatus for use in a variety of communications systems providing one or more payment alternatives for communication services and automatically selecting of a group of alternative payment techniques while significantly reducing the amount of interactive activity required from the user. Upon entry of a request to establish communications between calling and called electronic devices, the system initially looks towards a primary service provider. Absent acceptance of the request for service by the primary service provider, for whatever reason, the system automatically reverts to an alternative service provider and/or payment provider by searching data provided by the user and coupled to the electronic device for which a communication link is requested, eliminating the need for any further input by the user in the form of redialing the call, providing data through insertion of a debit or credit card, for example, identifying the alternative payment provider. The data identifying alternative service/payment providers may be contained in a card or chip removably insertable into the electronic device or in a storage device incorporated therein. Capability may be provided for choosing the most economic service/payment provider to be selected for honoring the request for service.

摘要： A controller (112) controls (706) at least two transmitters (302) to transmit at least two simulcast signals (502, 504) during a time period. The at least two simulcast signals produce intersymbol interference at a receiver. At least one of the transmitters changes (708) its output amplitude during a portion of the time period, thereby altering the intersymbol interference during the portion of the time period.

摘要： A base station (214) synchronizes a data stream of a second transmitter (202) with that of a first transmitter while maintaining full user traffic through a radio communication system (200). The first and second transmitters transmit (501), during a first time interval, a first portion of the user traffic in a simulcast mode; and at least the first transmitter transmits (503), during a second time interval, a second portion of the user traffic in a non-simulcast mode. A receiver (204) proximate the second transmitter monitors (505) the second portion of the user traffic transmitted from the first transmitter to determine a time delay, and then adjusts (507) a launch time of the second transmitter in accordance with the time delay.
