Methods and systems for periodically transmitting traffic channel assignment (TCA) messages in a radio access network are disclosed herein. An exemplary method involves (a) periodically transmitting a capsule that includes one or more TCA messages, wherein an async timer specifies a period that is used to periodically transmit the capsule; and (b) using one or more backhaul-latency indicators as a basis for determining the period that is used to periodically transmit the capsule. The method may further comprise periodically repeating (b) in order to dynamically update the async timer to reflect changes in backhaul latency.

Methods and systems for providing an enhanced best-effort quality of service (QOS) are provided. As third-party real-time applications may be unable to explicitly signal QOS requests in some environments, this enhanced best-effort QOS may be applied to real-time flows associated with third-party applications. For instance, devices in an access network may determine that a packet is part of a real-time flow of packets, and is associated with a third-party application. In response to this determination, these devices may forward the packet according to the enhanced real-time QOS.

Methods and systems for reducing the latency of instant communication session establishment are presented. According to various preferred embodiments, a RAN, may receive a setup request message via a packet-switched network. The RAN may determine, from a quality of service (QOS) indication contained in the setup request message, that the setup request message is requesting establishment of a instant communication session. The RAN may further determine an intended destination wireless communication device (WCD) for the setup request message. Based on the QOS indication and/or a profile indicating the destination WCD's capabilities, the RAN may pre-allocate resources for the instant communication session in parallel to paging the destination WCD. In this way, the latencies associated with these procedures are overlapped, thus reducing the overall latency of instant communication session establishment.

A method and system for avoiding missed tuneaways from a first wireless link configured according to a first protocol to a second wireless link configured according to a second protocol. An access network providing the first wireless link may receive, from one or more of a group of hybrid access terminals assigned to given cycles/timeslots of the first wireless link, reports of missed tuneaways from the first wireless link to the second wireless link. Based on the received reports, the access network may determine that the group of hybrid access terminals (or a given one of the group) has missed a threshold extent of tuneaways. In response, the access network may decide to reduce an amount of control-channel data to send on the first wireless link during the given cycles/timeslots and then begin to send a reduced amount of control-channel data on the first wireless link during the given cycles/timeslots.

Methods and systems are provided for adjusting the volume on a mobile station earpiece based on reverse frame data rate. In an embodiment of the invention, a mobile station transmits a plurality of reverse frames over a specified period of time. For each frame in the plurality of reverse frames, the mobile station measures a reverse frame data rate. The mobile station then uses the measured reverse frame data rates to calculate an average reverse frame data rate for the reverse frames transmitted over the specified period of time. Next, the mobile station adjusts the volume level of an earpiece based at least in part on the average reverse frame data rate.

Methods and systems for reducing communication session establishment latency are introduced. In a wireless communication network, a radio access network (RAN) determines that a wireless communication device (WCD), such as a mobile phone, is attempting to establish a communication session. Based on the quality-of-service sensitivity of the communication session as well as recent reports of wireless coverage quality received from the WCD, the RAN selects an appropriate timeout value. This selected timeout value is used for a timer associated with a communication session establishment message transmitted by the RAN to the WCD. As a result, the RAN can retransmit the communication session establishment message rapidly in situations where the communication session establishment message is more likely to be lost.
