摘要： The number of Reverse Activity Bits (RABs) equal to “1” per frame is a Congestion Overload (CO) metric used to determine whether the reverse link in a wireless communications system is in a congestion overload state due to a reverse link RF overload. When the value of the CO metric exceeds a first predetermined threshold that is indicative of a congestion overload condition, the system enters a block state where all new connection requests are blocked. Once in the block state, if the value of the CO metric does not decrease but continues to increase and exceeds a second higher threshold, the system enters a mute state. In the mute state a predetermined large percentage of existing active calls are muted. Specifically, a message is sent downlink to specific ATs instructing them to reduce their transmission rates to zero but to still maintain their active connections.

摘要： Multiple carriers are used to provide access to a wireless communication system. A first carrier transmits synchronization messages in accordance with the IS-95B standard (communication protocol revision 5). The synchronization message directs mobiles attempting to access the network to a paging channel on the first carrier. The paging channel enables mobiles conforming to a standard of IS-2000 revision 0 or older to access the wireless network. The paging channel also includes an extended global service redirection message (EGSRM) that instructs mobiles conforming to the IS-2000 revision A standard (communication protocol revision 7) to use a synchronization channel on a second carrier for reception of an IS-2000 revision A synchronization message. The IS-2000 revision A (communication protocol revision 7) synchronization message instructs the mobile to access the wireless communication network using a BCCH and/or FCCCH on the second carrier, or using a BCCH and/or FCCCH on the first carrier.

摘要： A method of wireless communication. The method includes the step of broadcasting a message, such as channel list message, for example. The broadcasting message lists each available carrier for each available frequency band in the wireless communication spectrum—e.g., 400 MHz and about 2100 MHz. Each available carrier listed within the message may correspond with at least one cell of a coverage area. Moreover, each broadcast message comprises at least one occurrence for each available carrier. Each available carrier may also be repeated within the message a number of times corresponding to a carrier weighting. This carrier weighting in turn corresponds with a traffic load. Alternatively, the method may also include the step of repeating the broadcast of the message a number of times, wherein the number corresponds to a carrier weighting associated with the traffic load. The broadcast message may also comprise a listing of at least one service, such as voice and/or data, supported by each available carrier.

摘要： When an overload condition is determined to exist at a base station in a wireless communications system based on the number of unsuccessful access attempts to access the system relative to the successful access attempts to access the system, the base station broadcasts a message to each mobile terminal within its coverage area that changes at least one access probe-related parameter associated with at least one of: the number, the frequency, and the power intensity of the access probes made by these mobile terminals as they attempt to establish access to the wireless network. By so limiting these access probes in some manner when an overload condition is present, the interference caused on the reverse link by many mobile terminals attempting access is reduced.
