Abstract:
1. A method for transmitting traffic channel assignment (TCA) messages in a radio access network, the method comprising: (a) periodically transmitting an asynchronous capsule that includes one or more TCA messages, wherein an asynchronous-capsule timer specifies a period that is used to periodically transmit the asynchronous capsule; and (b) using one or more backhaul-latency indicators as a basis for determining the period specified by the asynchronous-capsule timer, wherein: wherein periodically transmitting an asynchronous capsule comprises separately transmitting each of a plurality of asynchronous capsules, wherein transmission of a given one of the plurality of asynchronous capsules is separated from transmission of a next of the plurality of asynchronous capsules by the period specified by the asynchronous-capsule timer, wherein a first of the plurality of asynchronous capsules is transmitted at a first point in time with a first set of one or more TCA messages, and wherein, after transmitting the first asynchronous capsule and then waiting for the period specified by the timer, a second of the plurality of asynchronous capsules is transmitted with a second set of TCA messages, wherein the second set of TCA messages includes substantially all TCA messages received from a radio network controller (RNC) in between transmitting the first asynchronous capsule and transmitting the asynchronous second capsule.
