Abstract: A packet transmission system (100) for reducing request traffic contention and the likelihood of resource misallocation includes a communications controller (110) and a plurality of remote requesting units (112) requesting packet transmission services. In response to receipt of a request (302), the controller (110) transmits a grant (306) to a requesting unit (112) when packet transmission resources (304 and 310) are available or a request acknowledgment (306) when packet transmission resources (304 and 310) are unavailable. Each remote unit (112) comprises apparatus structure and method steps for transmitting requests (302) to the controller (110) and starting a first timer having an interval (T) determined as a function of a number (Q) of outstanding requests (302). Upon receipt of an acknowledgment (306), the remote unit (112) starts a second timer having an interval (T1) longer than the inverval (T). Upon expiration of either the first timer or the second timer, the remote unit (112) will then and only then transmit a duplicate request (302). By limiting the number of duplicate requests transmitted by a remote unit (112), the present invention operates to reduce request traffic contention and the likelihood of resource misallocation.

Abstract translation: 用于减少请求业务争用和资源错位的可能性的分组传输系统（100）包括：请求分组传输服务的通信控制器（110）和多个远程请求单元（112）。 响应于接收到请求（302），当分组传输资源（304和310）可用时，控制器（110）向请求单元（112）发送授权（306），或者当分组传输时，请求确认（306） 资源（304和310）不可用。 每个远程单元（112）包括用于向控制器（110）发送请求（302）并启动具有根据未完成请求的数量（Q）确定的间隔（T）的第一定时器的装置结构和方法步骤（302） ）。 在接收到确认（306）时，远程单元（112）启动具有比倒数（T）更长的间隔（T1）的第二定时器。 当第一定时器或第二定时器到期时，远程单元（112）然后将仅发送重复请求（302）。 通过限制由远程单元（112）发送的重复请求的数量，本发明操作以减少请求流量争用和资源错位的可能性。
