Abstract: A preferred roaming list (PRL) carries system and acquisition records for wireless wide area network (WWAN) systems and wireless local area network (WLAN) systems. New system and acquisition records may be defined for WLAN. The PRL and system and acquisition records may be defined to be backward compatible with TIA-683-C. System and acquisition information for WLAN systems may be stored in the new system and acquisition records, respectively. Information used to perform encryption and/or authentication for WLAN systems may be stored in a separate WLAN authentication profile table. The system record for each WLAN system indicates a acquisition record and a profile record for that WLAN system. A network identifier table may also carry system records and profile records for WLAN systems. The system records carry information used for WLAN system selection and acquisition. The profile records carry information used to perform encryption and/or authentication for WLAN systems.

Abstract translation: 优选的漫游列表（PRL）携带用于无线广域网（WWAN）系统和无线局域网（WLAN）系统的系统和采集记录。 可以为WLAN定义新的系统和采集记录。 PRL和系统和采集记录可以定义为向后兼容TIA-683-C。 WLAN系统的系统和采集信息可分别存储在新系统和采集记录中。 用于对WLAN系统执行加密和/或认证的信息可以存储在单独的WLAN认证简档表中。 每个WLAN系统的系统记录指示该WLAN系统的采集记录和简档记录。 网络标识符表还可以携带用于WLAN系统的系统记录和简档记录。 系统记录携带用于WLAN系统选择和采集的信息。 简档记录携带用于对WLAN系统执行加密和/或认证的信息。

Abstract: The access terminal is configured to wirelessly send to a data system a request that the data system assign an access terminal identifier (ATI) to the access terminal. The access terminal delays transmission of the request until after a user of the access terminal has employed the access terminal to request a packet data service from the data system. In some instances, the data system is an Evolution, Data Only (EV-DO) system and the access terminal identifier (ATI) is a Unicast Access Terminal Identifier (UATI) generated by the Evolution, Data Only (EV-DO) system.

Abstract translation: 接入终端被配置为向数据系统无线地发送数据系统向接入终端分配接入终端标识符（ATI）的请求。 接入终端延迟请求的发送，直到接入终端的用户已经使用接入终端从数据系统请求分组数据服务为止。 在某些情况下，数据系统是一种Evolution（仅数据）数据（EV-DO）系统，而接入终端标识符（ATI）是由Evolution，Data-only（EV-DO）系统生成的单播接入终端标识符（UATI）。

Abstract: Wireless devices with different capabilities may use a single file containing multiple (e.g., two) PRLs for system selection and acquisition. A first PRL in the file has a first (e.g., IS-683-A) format and includes PRL information for, e.g., 1x systems. A second PRL has a second (e.g., IS-683-C) format and includes PRL information for, e.g., 1x and 1xEV-DO systems or just 1xEV-DO systems. A legacy wireless device supporting only IS-683-A would read and use the first PRL for system selection and acquisition and ignore the second PRL. A wireless device supporting IS-683-C would read the second PRL and (1) use the second PRL by itself if it contains PRL information for both 1x and 1xEV-DO systems or (2) combine the first and second PRLs to generate a combined PRL if the second PRL contains PRL information for only 1xEV-DO systems.

Abstract: A wireless device receives a request to originate a data call, e.g., from the user or a higher layer application. If origination control is not to be applied, then the wireless device originates the data call immediately. Otherwise, the origination of the data call is controlled based on prior data call origination attempts that are applicable to the data call. For example, the wireless device may originate the data call immediately if (1) the most recent origination attempt was successful or (2) the most recent origination attempt was unsuccessful but a predetermined time period has elapsed since this unsuccessful origination attempt. If the most recent origination attempt was unsuccessful and the predetermined time period has not elapsed, then the wireless device may (1) wait until this predetermined time period elapses and then originate the data call or (2) reject the data call.

Abstract translation: 无线设备例如从用户或更高层应用接收到发起数据呼叫的请求。 如果不应用发起控制，则无线设备立即发起数据呼叫。 否则，根据适用于数据呼叫的先前的数据呼叫发起尝试来控制数据呼叫的发起。 例如，如果（1）最近的发起尝试成功，或者（2）最近的发起尝试不成功，但是从该不成功的发起尝试起经过了预定时间段，则无线设备可以立即发起数据呼叫。 如果最近的发起尝试不成功并且预定时间段没有经过，则无线设备可以（1）等待，直到经过该预定时间段，然后发起数据呼叫，或者（2）拒绝该数据呼叫。

Abstract: Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.
