    摘要： A system and method are provided for canceling interference present in a local channel signal received at a receiver. The system includes a controller and a finger demodulator assembly. The controller is capable of selecting at least one interfering pilot channel signal that has a signal strength above a threshold, where the selected interfering pilot channel signals comprises an interfering set of pilot channel signals. The finger demodulator assembly can then be capable of producing a corrected local channel signal based upon the interfering set of pilot channel signals during the idle state and/or access state.

    摘要： A policy that governs access to a resource may be tested against real-world access requests before being used to control access to the resource. In one example, access to a resource is governed by a policy, referred to as an effective policy. When the policy is to be modified or replaced, the modification or replacement may become a test policy. When a request is made to access the resource, the request may be evaluated under both the effective policy and the test policy. Whether access is granted is determined under the effective policy, but the decision that would be made under the test policy is noted, and may be logged. If the test policy is determined to behave acceptably when confronted with real-world access requests, then the current effective policy may be replaced with the test policy.

    摘要翻译： 管理对资源的访问的策略可以在被用于控制对资源的访问之前被针对真实的访问请求进行测试。 在一个示例中，对资源的访问受政策管辖，被称为有效策略。 当修改或更换策略时，修改或替换可能成为测试策略。 当请求访问资源时，可以根据有效策略和测试策略对请求进行评估。 是否授予访问是根据有效策略确定的，但是将根据测试策略作出的决定被注明，并可能被记录。 如果测试策略在面对现实访问请求时被确定为可接受的行为，则可以用测试策略替换当前的有效策略。
