Abstract

Systems, methodologies, and devices are described that employ indicators related to a parameter value(s) associated with a neighbor cell to facilitate communication by a mobile device in a network. The mobile device optionally can read a parameter value associated with a detected neighbor cell, and can provide, to the serving base station, signal strength information and indicator information that indicates whether, the mobile device read the parameter value. The serving base station can select a cell to which the mobile device is to be communicatively connected based in part on evaluating the received information. If a parameter value is not read by the mobile device, the serving base station can request the parameter value from a neighbor cell. The neighbor cell can provide a one-to-one indicator to indicate when a specified parameter value is to be applied with regard to a particular base station.
