摘要： A network selection method for a mobile station which is associated with a Home Public Land Mobile Network (HPLMN) identified by a home Mobile Network Code (MNC) and Mobile Country Code (MCC) pair. The mobile station identifies a plurality of PLMNs in a geographic area, and selects a non-home PLMN identified by a non-home MNC/MCC pair and designated as a Registered PLMN (RPLMN). In response to regaining signal coverage from an out-of-coverage condition with the RPLMN, or being powered-on from a power-off state entered while operating with the RPLMN, the mobile station selects the HPLMN if the HPLMN identified by the home MNC/MCC pair is available. Otherwise, if the HPLMN is unavailable and the RPLMN identified by the non-home MNC/MCC pair is available, the mobile station selects the RPLMN. However, if the RPLMN is unavailable, the mobile station selects an alternate PLMN in accordance with an automatic or manual network selection method.

摘要翻译： 一种与家庭移动网络代码（MNC）和移动国家代码（MCC）对识别的归属公共陆地移动网络（HPLMN）相关联的移动站的网络选择方法。 移动站识别地理区域中的多个PLMN，并且选择由非归属MNC / MCC对标识并被指定为注册PLMN（RPLMN）的非归属PLMN。 响应于从RPLMN的覆盖不完整状态恢复信号覆盖，或者在使用RPLMN操作时从输入的电源关闭状态接通电源，如果由家庭MNC识别的HPLMN，则移动台选择HPLMN / MCC对可用。 否则，如果HPLMN不可用，并且由非归属MNC / MCC对标识的RPLMN可用，则移动台选择RPLMN。 然而，如果RPLMN不可用，则移动台根据自动或手动网络选择方法选择备用PLMN。
