    • Various embodiments for providing multi-band operation in a mobile computing device are described. In one or more embodiments, a mobile computing device may be arranged to support quad-band GSM communication in the GSM-850, GSM-900, GSM-1800, and GSM-1900 frequency bands. The mobile computing device may be arranged to determine a starting frequency band based on the home country and home network. By using the determined starting frequency band associated with the home country and home network of the user, fewer and/or shorter delays may be experienced when searching for and acquiring an available frequency. Once a network search is completed, the mobile computing device may be arranged to determine whether a network can be found in current frequency band pair for normal service, to disconnect from the acquired network if normal service is not supported, and to intelligently search for an available frequency in a different frequency band. Other embodiments are described and claimed.
    • 描述了用于在移动计算设备中提供多频带操作的各种实施例。 在一个或多个实施例中,移动计算设备可以被布置成支持在GSM-850,GSM-900,GSM-1800和GSM-1900频带中的四频GSM通信。 移动计算设备可以被布置为基于本国和家庭网络来确定起始频带。 通过使用与用户的本国和家庭网络相关联的确定的起始频带,在搜索和获取可用频率时可能会遇到更少和/或更短的延迟。 一旦网络搜索完成,移动计算设备可以被布置为确定是否可以在正常服务的当前频带对中找到网络,如果不支持正常服务,则从所获取的网络断开连接,并且智能地搜索 可用频率在不同的频带。 描述和要求保护其他实施例。

    • Techniques for accessing wireless networks are disclosed. For instance, an apparatus may include a control module to broadcast messages for transmission within a coverage area of a first type of a wireless communications network. In addition, the apparatus may include a storage medium that stores access parameters for wireless network(s) of a second type that are accessible within the coverage area. Additionally, the control module may generate messages for transmission that include the one or more access parameters. The types of wireless communications networks may be, for example, wireless cellular networks and wireless data communications networks.
    • 公开了用于访问无线网络的技术。 例如,装置可以包括控制模块,以广播用于在第一类型的无线通信网络的覆盖区域内传输的消息。 另外,该装置可以包括存储介质,该存储介质存储在覆盖区域内可访问的第二类型的无线网络的访问参数。 另外,控制模块可以生成包括一个或多个访问参数的用于传输的消息。 无线通信网络的类型可以是例如无线蜂窝网络和无线数据通信网络。
