Abstract: Visiting place access is an effective way to address bottlenecks in roaming bandwidth between provinces. In this paper, we
discuss on the key technologies for transforming access from attribution place to visiting place, so as to effectively identify the target
users through the comprehensive judgment of specific contract information, reduce roaming delay and enhance user perception.
