Abstract: A system for facilitating the acquisition of a most desirable wireless service for a wireless phone. The system includes a scanning mechanism for periodically scanning for a signal indicative of a wireless service having a coverage area that overlaps one or more coverage areas of other wireless services. A service acquisition mechanism acquires the wireless service or one of the other wireless services based on predetermined selection criteria and the signal. More specifically, the present invention includes a wireless phone having a first mechanism for determining if a detected system, i.e., service is associated with a coverage area that overlaps one or more coverage areas of different systems. A second mechanism compares the different systems to the detected system and selects a preferred system based on the comparison. A third mechanism acquires the preferred system. In the specific embodiment, the wireless phone includes a computer that runs software for implementing the first, second, and third mechanisms.

Abstract: A method and apparatus for acquiring an emergency service from one or more candidate mobile radio communication systems. An attempt is made by the mobile radio unit to acquire normal non-emergency service. If the attempt of acquiring normal non-emergency services fails and the user needs to originate an emergency call, an emergency scan list containing one or more candidate mobile radio communication systems is scanned, and an attempt is made to acquire emergency service from one of these systems. The emergency scan list is different from the normal preferred roaming list stored in the mobile radio unit. Next, the invention originates an emergency call in accordance with the service acquired from the emergency scan list.

Abstract: A system for facilitating the acquisition of a most desirable wireless service for a wireless phone. The system includes a scanning mechanism (83) for a periodically scanning for a signal indicative of a wireless service having a coverage area that overlaps one or more coverage areas of other wireless services. A service aquisition mechanism (87) acquires the wireless service or one of the other wireless services based on predetermined selection criteria and the signal. More specifically, the present invention includes a wireless phone (26) having a first mechanism (85) for determining if a detected system, i.e., service is associated with a coverage area that overlaps one or more coverage areas of different systems. A second mechanism (84) compares the different systems to the detected system and selects a preferred system based on the comparison. A third mechanism (87) acquires the preferred system. In the specific embodiment, the wireless phone includes a computer that runs software for implementing the first, second, and third mechanisms.

Abstract translation: 一种用于促进无线电话获取最理想的无线服务的系统。 该系统包括扫描机构（83），用于周期性地扫描指示具有与其他无线服务的一个或多个覆盖区域重叠的覆盖区域的无线服务的信号。 服务采集机构（87）基于预定的选择标准和信号来获取无线服务或其他无线服务之一。 更具体地，本发明包括一种无线电话（26），其具有用于确定检测到的系统（即服务是否与覆盖区域相关联的第一机制），覆盖区域与不同系统的一个或多个覆盖区域重叠。 第二机制（84）将不同系统与检测到的系统进行比较，并且基于比较选择优选系统。 第三种机制（87）获取首选系统。 在具体实施例中，无线电话包括运行用于实现第一，第二和第三机制的软件的计算机。
