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.

The present invention provides a method of providing a group paging message. One embodiment of the method includes providing a first message during a first portion of a predetermined time period. The first message includes information indicating a second portion of the predetermined time period during which at least one idle first mobile unit is to wake up and attempt to receive a second message from the base station(s). The embodiment of the method also includes providing a third message during a third portion of the predetermined time period. The third message includes information indicating the second portion of the predetermined time period during which at least one idle second mobile unit is to wake up and attempt to receive the second message. The third portion of the predetermined time period is different than the first portion.

A method is provided for sending messages to a plurality of access terminals in a wireless network. The method comprises broadcasting a multicast message along with a predetermined address associated with the plurality of access terminals. The multicast message and the address associated with a plurality of access terminals is received at an access terminal. The access terminal compares the received address with a locally stored address, and the message is accepted in response to the received and locally stored addresses being the same. If the received and locally stored addresses are different, then the multicast message is discarded.

A method is provided for controlling delivery of packets over a synchronous control channel in a wireless system employing the High Rate Packet Data (HRPD) standard. The synchronous channel is comprised of a plurality of slots, and a first packet is sent over the synchronous control channel in a first one of the plurality of slots along with an indication of a second one of the plurality of slots in which a second packet will be delivered. Thereafter, the second packet is sent over the control channel in the second one of the plurality of slots. Subsequent packets are handled similarly.

For applications with very small data activities, connection of a UE to a wireless network for sending or receiving such small data traffic increments via conventional connection set-up processes is quite inefficient in terms of spectral resource utilization. The invention provides a new connectionless methodology for transmission of such small data increments between a UE and a serving eNB. In particular, the invention methodology contemplates identifying a set of preamble sequences among the pool of preamble sequences provided for access requests from a UE to an eNB via the Random Access Channel as corresponding to a request from the UE for access to transmit an increment of data smaller than a predetermined threshold data size. When a UE has data traffic to transmit of a size smaller than the predetermined threshold size, it selects one of the preamble sequences in the identified set and sends an access request, using the selected preamble sequence, to a serving eNB via the Random Access Channel. Upon receipt of the access request from the UE, the eNB determines an appropriate RF resource for the data increment sought to be transmitted by the UE, based on the use of the selected preamble sequence sent by the UE, and schedules an uplink connection for the transmission of that data increment by the UE.
