Abstract: Aspects of the disclosure provide a processing circuit in an electronic apparatus and a method to switch the electronic apparatus during an inter-system handover (HO) process from a source network system to a target network system. The processing circuit can include an inter-system HO signal processing module and a mapping module. The inter-system HO signal processing module can be configured to obtain a mapping relationship between a set of source bearers associated with the source network system and a first set of target bearers associated with the target network system based on quality of service (QoS) characteristics associated with the set of source bearers and the first set of target bearers. The mapping module can be configured to obtain a second set of target bearers based on resources allocated to the first set of target bearers by the target network system and to obtain a third set of target bearers that is based on the first and second set of target bearers.

Abstract: A method of maintaining a proper forbidden tracking area identifier (TAI) list is proposed. A UE receives a service area list comprising one or more allowed tracking areas. The service area list may be carried by a configuration update command. UE compares if any of the allowed tracking area having a matching TAI in the forbidden TAI list. Accordingly, UE removes any allowed tracking areas having a matching TAI from the forbidden TAI list. In one embodiment, UE sends a REGISTRATION REQUEST message to initiate a registration procedure. In response, UE receives a REGISTRATION ACCEPT message, which may also carry a service area list. UE may remove the allowed tracking area having a matching TAI from the forbidden TAI list. However, if UE is registered for emergency services, then UE shall not remove the allowed tracking area from the forbidden TAI list.

Abstract: A method for UE route selection policy (URSP) rule matching is proposed. URSP is used by a UE to determine if a detected application can be associated to an established PDU session, can be offload to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU session. The UE first finds a non-default URSP rule with a matching traffic descriptor to the application. When the UE fails to find existing PDU session or setup new PDU session with any or the route selection descriptors of the non-default URSP rule, the UE moves to another non-default URSP rule, if any, and try the matching. If all non-default URSP rules cannot be matched with the application, then the UE tries the default URSP rule, which includes a match-all traffic descriptor.

Abstract: A method of enhanced handling of a Forbidden Public Land Mobile Network (PLMN) list is proposed. When a UE tries to attach to a PLMN and receives an ATTACH Reject message having no integrity protection, it could be transmitted from a network entity trying to block the PLMN for providing service. Therefore, by introducing a temporary forbidden PLMN list and a timer T3247, UE can avoid adding the PLMN ID to the Forbidden PLMN list and avoid being blocked for network access. Instead, UE is only temporary refrained from selecting the PLMN ID and is able to retry for the network access after T3247 expiry. The temporary list together with T3247 mechanism thus gives UE more opportunity to try with the same PLMN ID at a different time and/or a different UE location, where the malicious blocking is no longer available.

Abstract: A method of managing default QoS rules for PDU session is proposed. A PDU session defines the association between the UE and the data network that provides a PDU connectivity service. Each PDU session is identified by a PDU session ID, and may include multiple QoS flows and QoS rules. There can be more than one QoS rule associated with the same QoS flow. A default QoS rule is required to be sent to the UE for every PDU session establishment and it is associated with a QoS flow. Within a PDU session, there should be one and only one default QoS rule. In one novel aspect, UE behavior and error handling for proper QoS rule management is defined for PDU session establishment and modification procedures to enforce the one and only one default QoS rule policy.

Abstract: A method of defining ATtention (AT) commands for 5G session management operations is proposed. In one example, the AT command can be a set command for configuring a PDU session establishment procedure. Additional 5G parameters including PDU session ID, Single-Network Slice Selection Assistance Information (S-NSSAI), Service and Session Continuity (SSC) mode, access type, and Reflective QoS (RQ) indication are defined for AT command +CGDCONT to configure the PDU session. In another example, the AT command can be a read command for querying PDU session and QoS flow parameters. Additional 5G parameters including PDU session ID (PSI), QoS flow ID (QFI), S-NASSI, SSC mode, access type, and RQ timer are defined for AT command +CGCONTRDP or +CGSCONTRDP.

Abstract: Various solutions for avoiding circuit-switched call drop with respect to user equipment and network apparatus in mobile communications are described. An apparatus transmits a non-access stratum (NAS) message in a NAS signaling connection. The apparatus receives a NAS response message. The apparatus initiates a timer to control the NAS signaling connection. The apparatus further receives a circuit-switched (CS) service notification. The apparatus then stops the timer and execute a CS service procedure.

Abstract: Various examples pertaining to reflective quality of service (QoS) control in wireless communications are described. A user equipment (UE) receives from a wireless network control signaling that activates support of reflective QoS by the UE. The UE determines whether a predefined condition exists. The UE then indicates to the wireless network a change in a capability of the UE to support the reflective QoS responsive to the determining indicating that the predefined condition exists. When the UE receives from the wireless network control signaling that activates support of reflective QoS by the UE, the UE deletes one or more UE-derived QoS rules among a plurality of active UE-derived QoS rules each with a respective reflective QoS (RQ) timer running.

Abstract: Solutions are proposed to facilitate the support of 3GPP PS_Data_Off feature. The PS_Data_Off feature prevents transport via 3GPP access of all IP packets except those related to 3GPP PS_Data_Off Exempt Services. In one example, signaling storms due to frequent PS_Data_Off reconfiguration are prevented. In another example, for multi-SIM devices and for devices that supporting WiFi access, UE reconfigures the PS_Data_Off feature upon a triggering condition is satisfied. In yet another example, upon status change of PS_Data_Off feature, UE initiates RAT change to improve performance, to reduce power consumption and cost, and to maintain service continuity. Furthermore, new AT commands and parameters are introduced to enable the PS_Data_Off feature.
