    摘要： A mobile UE initiates a full search of all supported frequencies upon detecting a change in the Mobile Country Code (MCC) transmitted by a PLMN. The change in MCC indicates the user had crossed a political border, and the spectrum allocated for wireless communication may be different. In one embodiment, the mobile UE stores the current MCC. Upon obtaining an updated MCC, it is compared to the stored MCC. If the updated MCC is different from the stored MCC, the full frequency search is initiated. To prevent excessive searching, with concomitant power consumption, while traveling near a border, the UE waits a predetermined duration after an MCC-initiated full scan before conducting a subsequent full scan, even if the MCC changes within that duration.

    摘要翻译： 移动UE在检测到由PLMN发送的移动国家代码（MCC）的变化时发起对所有支持的频率的全面搜索。 MCC的变化表明用户已经越过政治边界，分配给无线通信的频谱可能不同。 在一个实施例中，移动UE存储当前MCC。 在获得更新的MCC后，将其与存储的MCC进行比较。 如果更新的MCC与存储的MCC不同，则启动全频搜索。 为了防止过多的搜索，随着功率消耗，在边界附近行驶时，即使MCC在该持续时间内变化，UE在进行后续的全扫描之前等待MCC启动的全扫描之后的预定持续时间。
