Abstract: Techniques for reliable transmission of higher priority data within a frame are disclosed. In one aspect, an inner code is applied to one or more partial segments of a transmitted data frame in addition to any outer code applied to the entire frame. In another aspect, inner coded segments of a received frame are decoded when decoding of the outer code indicates one or more errors within the frame. The inner coded segment is retained when the inner decoding decodes without error. Various other aspects are also disclosed. These aspects have the benefits of reducing the number of retransmissions of higher priority data, as well as reducing delay for time-sensitive segments of the frame. The result is more efficient use of bandwidth, more responsiveness to higher priority segments, such as signaling traffic, and capacity, power, and other efficiencies associated therewith.

Abstract: Method for reducing backlogged calls is disclosed. According to one embodiment, an initial parameter set providing an initial blocking probability and a timestamp is received. A current time index is determined based on the timestamp. Following, a current blocking probability is calculated based on the initial blocking probability and the current time index. The initial parameter set can also provide a delay period, a throughput rate, an expected new call rate and an initial backlog. The initial blocking probability can be determined, for example, from the throughput rate, expected new call rate and initial backlog. An elapsed time between the timestamp and the current system time is determined, and a current time index is determined by dividing the elapsed time by the delay period. A call request is blocked, for example, when a randomly generated number between 0 and 1 is less than the current blocking probability.

Abstract: Method for segmented message transmission wherein each message is first divided into segments and the segments are fragmented. A segment parameter is applied to each segment, and a segment identifier to each fragment. The fragments are provided to a lower level for preparation into frames for transmission. One embodiment is applied to the transmission of short duration messages, such as control messages. On receipt of a frame within a segment, a timer is initiated having an expiration period. Receipt of a next frame in the segment stops the timer. Expiration of the expiration period for a timer indicates that a next sequential frame is lost.

Abstract: Method for segmented message transmission wherein each message is first divided into segments and the segments are fragmented. A segment parameter is applied to each segment, and a segment identifier to each fragment. The fragments are provided to a lower level for preparation into frames for transmission. One embodiment is applied to the transmission of short duration messages, such as control messages. A timer is used to detect an erasure within a plurality of transmission frames, wherein the timer uses an average inter-arrival time period between transmitted frames to determine a missing frame. In one embodiment, the time period is given as &agr;*AIT, wherein &agr; is a constant value, and AIT is the average inter-arrival time of frames.

Abstract: In a communication system (100), a method and apparatus provide for efficient control of call requests from mobile stations (102-104) to base station (101). Mobile station (102-104) receives an initial call request block probability from base station (101), determines an elapsed time from an effective time of the initial call request block probability, and adjusts the initial call request block probability based on an elapsed time. Mobile station (102-104) uses the adjusted initial call request to block call request.
