    Abstract: Se proponen soluciones para facilitar el soporte de la característica PS_Datos_Apagado 3GPP; la característica PS_Datos_Apagado evita el transporte a través del acceso 3GPP de todos los paquetes IP excepto aquellos relacionados con Servicios de Exención de PS_Datos_Apagado 3GPP; en un ejemplo, se pueden evitar tormentas de señalización a causa de una reconfiguración frecuente de PS_Datos_Apagado; en otro ejemplo, para dispositivos multi-SIM y para dispositivos que soportan acceso WiFi, el UE reconfigura la característica PS_Datos_Apagado al momento en que se satisface una condición de disparo; en otro ejemplo todavía, al momento de un cambio de estatus de la característica PS_Datos_Apagado, el UE inicia el cambio de RAT para mejorar el desempeño, reducir el consumo de potencia y costo y mantener la continuidad del servicio; además, se introducen nuevos comandos AT y parámetros para habilitar la característica PS_Datos_Apagado.

    Abstract: A method is proposed for handling a 5G PDU session establishment procedure when a maximum number of active 5G PDU sessions has been reached. When the number of active 5G PDU sessions has reached the maximum number of active PDU sessions as defined for the PLMN/SNPN, a UE needs to release an existing 5G PDU session in order to add a new 5G PDU session. In one novel aspect, the UE can select a 4G PDN connection and release the selected PDN connection to fulfill the requirement for having number of 5G PDU session less than or equal to the maximum number of active 5G PDU sessions. The selected 4G PDN connection is established as a user-plane resource for an MA PDU session; by releasing the selected PDN connection, the UE is then able to establish a new PDU session, including an emergency PDU session in 5GS.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a mobile station (MS). The MS registers to a first public land mobile network (PLMN) over a first access technology (AT). The MS determines that a received signal quality of the first PLMN over the first AT is lower than the operator controlled signal threshold per access technology. In response, the MS periodically attempts to obtain service on the first PLMN over a second AT. A received signal quality of the first PLMN over the second AT is equal to or greater than an operator controlled signal threshold per access technology.

    Abstract: A method of handling de-registration and EPS mobility management (EMM) parameter for 3GPP when UE receives a de-registration request message via non-3GPP is proposed. There is an access type in the de-registration type IE in the de-registration request message. In one novel aspect, a UE handles EMM parameters of the de-registration procedure depending on the received access type in the de-registration type IE. Upon receiving a DEREGISTRATION REQUEST message, if the de-registration request is for 3GPP access or for 3GPP access and non-3GPP access, the UE performs a local release of the PDU sessions over 3GPP access and non-3GPP access, if any. Based on the 5GMM cause, UE also handles the corresponding EMM parameters including EMM state, EPS update status, 4G-GUTI, last visited registered TAI, TAI list, eKSI and attach attempt counter.

    Abstract: A method of handling Paging Early Indication with Paging Subgrouping (PEIPS) assistance information when a UE is registered to the same or different PLMN/SNPN networks is proposed. The PEIPS assistance information includes PEIPS parameters such as a PEIPS subgroup ID that is used by the UE for monitoring paging with PEIPS for power saving. If the UE registers to the same PLMN/SNPN via 3GPP access and non-3GPP access, then the UE handles the PEIPS parameters as one common parameters. If the UE registers to different PLMN/SNPN via 3GPP access and non-3GPP access, then the UE handles the PEIPS parameters as two independent parameters.

    Abstract: A method for handling a PDU session release command for releasing an MA PDU session with a PDN connection established as user-plane resource on 3GPP access is proposed. For an MA PDU session with both EPS/4G 3GPP leg and 5GS non-3GPP leg, if UE/NW wants to release the MA PDU session, UE/NW needs to initiate two procedures. First/Second, to release the EPS 3GPP leg, UE/NW should initiate a PDN disconnect procedure/deactivate EPS bearer context procedure or a detach procedure. Second/First, to release the 5GS non-3GPP leg, UE/NW should initiate a PDU session release procedure. The UE/NW can also initiate two procedures simultaneously. It is also possible that the UE initiates one procedure and the NW initiates the other procedure.
