Abstract: Method and apparatus are described for wireless communication. A user equipment (UE) located at a public land mobile network (PLMN) border area may modify cell selection parameters in order to leave a current PLMN for a more favorable visited PLMN (VPLMN). The UE may, for example, identify the border area by monitoring GPS coordinates, identifying a mobile country code (MCC) of a network, searching for a background PLMN after experiencing a number of uplink transmit failures, or by detecting a high block error rate (BLER). Additionally or alternatively, the UE may have certain physical or environmental constraints that create a mismatch between the Downlink (DL) reception range and the Uplink (UL) transmission range, and this mismatch may be a basis for, or may be accounted for, in modifying cell selection parameters.
