Abstract: The present disclosure presents a method and an apparatus for searching for service when a multi-mode UE goes out of service (OOS). For example, the disclosure presents a method for receiving a request to scan frequencies of a RPLMN of a first RAT and scanning the frequencies of the first RAT based on an acquisition database (ACQ DB). In addition, such an example method, may include sending an available PLMN list to the NAS layer, switching to a second RAT based on a request from the NAS layer, scanning frequencies of the second RAT based on the ACQ DB, and camping on a frequency of the second RAT found during the scanning of the frequencies of the second RAT based on the ACQ DB. As such, a method and an apparatus for searching for service when a multi-mode UE goes OOS may be achieved.

Abstract translation: 本公开提供了当多模式UE停止服务（OOS）时搜索服务的方法和装置。 例如，本公开提供了一种用于接收扫描第一RAT的RPLMN的频率的请求并基于获取数据库（ACQ DB）扫描第一RAT的频率的方法。 此外，这样的示例方法可以包括：向NAS层发送可用的PLMN列表，基于来自NAS层的请求切换到第二RAT，基于ACQ DB扫描第二RAT的频率，以及在 基于ACQ DB扫描第二RAT的频率期间发现的第二RAT的频率。 因此，可以实现当多模UE进入OOS时搜索服务的方法和装置。

Abstract: Embodiments of the present invention include devices, systems and methods for efficient PLMN searching. One method can include initiating a service search procedure. A list of channels to perform a power scan on is prepared. One or more channels are removed from the list of channels that use a same public land mobile network as a camped on cell. Frequencies of the channels are obtained from system information. A power scan is performed on the channels in the list of channels to obtain power scan results. One or more channels are removed from the power scan results. An acquisition process is performed on the channels in the power scan results. Other aspects, embodiments and features are also claimed and described.
