Abstract: Methods and apparatuses are provided that prevent a user equipment (UE) from entering into a permanent out of service (OOS) state. The UE receives a registration reject message associated with a permanent cause when the UE triggers a registration request for registering with a first network entity. It is determined whether the UE was previously registered with a second network entity upon receiving the registration reject message associated with the permanent cause. The UE stores a network entity identifier of the first network entity in a temporary forbidden list when the UE was previously registered with the second network entity, to prevent the UE from entering into the permanent OOS state.

Abstract: A method and system for minimizing delay in circuit-switched fallback (CSFB) procedure is disclosed. The disclosed method provides two different approaches for optimizing the delay during the CSFB procedure. In the first approach, user equipment (UE) receives a Location Area Identifier (LAD along with the Radio Access Technology (RAT) information from the network (LTE network). The UE uses the received RAT information from the network for switching to the target Radio Access Network (RAN) without intimating to the LTE network. In another approach, the UE obtains the RAT information by performing a background scan in idle mode, when the UE receives LAI without RAT information from the network.

Abstract translation: 公开了一种用于最小化电路交换回退（CSFB）过程中的延迟的方法和系统。 所公开的方法提供了两种不同的方法来优化CSFB过程中的延迟。 在第一种方法中，用户设备（UE）从网络（LTE网络）接收位置区域标识符（LAD以及无线接入技术（RAT））信息，UE使用从网络接收的RAT信息切换到目标 无线接入网（RAN），无需接入LTE网络，另一种方法是当UE从网络接收到没有RAT信息的LAI时，通过在空闲模式下执行后台扫描，获得RAT信息。
