A communication system and method assigns, such as by marking headers of wireless communication packets, packet classification data to packets to define at least one of the following classes: a control signaling class, such as in-band signaling and control packets, a voice class, a data retransmission class, OAMP class and a data class and wherein each class represents a different transmission priority over a backhaul link. For wireless communication packets associated with the control signaling class and the voice class, the method and apparatus assigns each of the wireless communication packets with additional drop precedent data wherein the drop precedence data defines a further packet drop priority within the control signaling class and the voice class. The apparatus and method drops a queued classified wireless communication packet based on a priority level of assigned drop precedent data and based on the packet classification data.

Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (), fixed network equipment (FNE) () selects a first subset of members () from the targeted group () of units and signals those members to join the group call session. Various techniques for selecting the first subset may be employed depending on what system benefits are desired. A second subset of members () from the targeted group of units is also selected and signaled to join the session. This second subset may be used to invite additional units in order to achieve a maximum number of group participants. Alternatively, the second subset may be used to invite a different unit (or units) to participate. This can be triggered by a user request to invite another subset to the group session, as could occur when the user is not able to resolve the particular matter at-hand with the group members of the first subset.

An apparatus and method for increasing Scheduling Request efficiency in a wireless communication system includes a step of configuring periodic timing opportunities for sending the scheduling request. A next step includes detecting new data arriving in an empty queue to trigger a scheduling request. A next step includes sending a scheduling request at selected SR opportunities until a response to the scheduling request is generated.

At lease one operating condition associated with an end user () of a network is obtained. Based upon the operating condition, a high bit-rate media feed being made to the end user () is halted. Thereafter, a lower bit rate media feed may be supplied to the end user in place of the high bit-rate media feed.

A system and method reduce latency involved in delivery of content to a handheld device. A sample channel comprises a plurality of content segments. Each content segment comprises recent content from one channel of a plurality of channels available for request by a subscriber. The sample channel is received by a handheld device and is not requested by the subscriber. The plurality of content segments are stored in a memory associated with the device. Upon detecting a request from the subscriber to view a specified channel, the content segment corresponding to the specified channel is located in memory and displayed on the device. A request is made for subsequent content from the specified channel, the subsequent content starting at or before the end of the content segment. Playback of the subsequent content is then initiated such that the subsequent content starts at a time when the content segment ends.

For a packet, a communication device determines () a length of a packet length field based on one or more of the following: a size of a transmit region allocated for a remote unit, a size of a transmit region allocated for a remote unit and not to be used for at least one other packet, and/or whether the packet length of the packet is indicated by a history of packet lengths of previously transmitted packets. The communication device may also or alternatively determine () a length of a connection identifier field based on a number of connection identifiers previously established. The communication device then transmits () the packet, which includes the field(s) of determined length. By determining the lengths of these fields in this manner, the fields may be made shorter and their use may potentially reduce signaling overhead as compared to using the present-day fixed-length fields.
