Abstract: Methods and apparatus are provided to reduce service interruption for intra-RAT and inter-RAT handover procedures. The UE performs a NAS signaling procedure via a NAS signaling connection in a mobile communication network. The UE monitors a radio resource status and determines whether a radio bearer has been or is being established for a RRC connection for data transmission. The UE determines whether to release the NAS signaling connection after completing the NAS signaling procedure based on whether the radio bearer has been established. In one embodiment, the UE monitors a radio resource status and determines whether a radio bearer has been established for a RRC connection for data transmission. The UE determines whether to start a timer upon completing the NAS signaling procedure based on whether the radio bearer has been or is being established.

Abstract: A method of applying a network forbidden list for enhanced service recovery in mobile communication networks is provided. In a first embodiment, upon receiving an error cause for a RAT in a selected network, a UE stores a PLMN ID, the RAT information, and the error cause as an entry in the forbidden list. The UE will not select to the RAT of the network stored in the forbidden list until the PLMN/RAT entry is removed from the forbidden list. In a second embodiment, upon receiving an error cause in a selected network, a UE stores a PLMN ID, the error cause, and a timer value as an entry in the forbidden list. The UE will not select to the network stored in the forbidden list until the timer associated with the PLMN ID is expired.
Abstract translation: 提供了一种在移动通信网络中应用用于增强业务恢复的网络禁止列表的方法。 在第一实施例中，UE在接收到所选择的网络中的RAT的错误原因时，将PLMN ID，RAT信息和错误原因作为禁止列表中的条目存储。 在不被禁止的列表中删除PLMN / RAT条目之前，UE不会选择存储在禁止列表中的网络的RAT。 在第二实施例中，在接收到所选择的网络中的错误原因之后，UE将PLMN ID，错误原因和定时器值存储为禁止列表中的条目。 直到与PLMN ID相关联的定时器到期，UE将不会选择存储在禁止列表中的网络。

Abstract: A network accessing method includes performing a cell search procedure for a first RAT; receiving first SI from a first cell of the first RAT when the first cell has been found in the cell search procedure; determining whether second SI is scheduled by the first cell according to content of the first SI; receiving the second SI in response to determination of the second SI being scheduled and deriving information regarding a second cell of a second RAT different from the first RAT; searching for the second cell according to the information regarding the second cell; and attempting to access the second cell instead of the first cell when the second cell has been found. The first cell is configured to provide access to a first core network and the second cell is configured to provide access to a second core network different from the first core network.

Abstract: Examples pertaining to flexible radio access technology (RAT) selection for 5th Generation (5G) mobile communications are described. A user equipment (UE) may receive, from a network node of a wireless network, information related to a RAT preference with respect to RAT selection by the UE. Based at least in part on the received information, the UE may perform a RAT or Public Land Mobile Network (PLMN) selection procedure. Alternatively, or additionally, the UE may receive, from the network node, information related to ability of one or more neighbor network nodes of one or more RATs in a region. Based at least in part on the received information, the UE may select one of the one or more RATs or one of the one or more neighbor network nodes.
