Abstract: Various solutions for enhancing quality of service (QoS) based on environmental conservation in mobile communications are described. An apparatus may determine whether an eco-friendly condition associated with a data session is met. Also, the apparatus may determine to modify a QoS associated with the data session in an event that the eco-friendly condition associated with the data session is met.

Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.

Abstract: A method for handling a PDU session status IE for MBS when the PDU session status IE indicates that the PDU session is inactive is provided. A UE receives a service accept or a service reject message from the network, which comprises a PDU session status IE indicating that a PDU session is inactive. Accordingly, the UE locally releases the PDU session if the PDU session is active, and determines if the PDU session is associated with one or more MBS sessions. If so, the UE locally leaves the associated MBS sessions. The PDU session can be a single access PDU session or a multiple access PDU session.

Abstract: The present invention provides a filtering circuit comprising a poly phase filter and a quadrature phase detector. The poly phase filter comprises a first path, a second path, a third path and a fourth path. The first path is configured to receive a first input signal to generate a first clock signal. The second path comprising a first adjustable delay circuit is configured to receive the first input signal to generate a second clock signal. The third path comprising a second adjustable delay circuit is configured to receive a second input signal to generate a third clock signal. The fourth path is configured to receive the second input signal to generate a fourth clock signal. The quadrature phase detector is configured to detect phases of these clock signals to generate control signals to control the first adjustable delay circuit and the second adjustable delay circuit.

Abstract: When a UE is registered to the same PLMN or SNPN over 3GPP and non-3GPP access, the UE and the AMF maintain one 5G-GUTI that is common to both 3GPP and non-3GPP access. When the UE is required to re-register to the network, the UE follows the procedures of deregister over both accesses, delete the common shared 5G-GUTI, and re-register over both accesses. The UE needs to perform the above procedures in a graceful sequence. In one novel aspect, the UE triggers the re-registration (either over 3GPP or non-3GPP access) after the completion of deregistration over both 3GPP and non-3GPP access. In addition, the UE deletes the common 5G-GUTI only after the completion of deregistration over both 3GPP and non-3GPP access.

Abstract: A method for route selection policy (URSP) rule matching enhancement in EPS is proposed. When an application is executed, the upper layer of a UE sends the application information to URSP entity for matching a URSP rule. The UE selects and evaluates a route selection descriptor (RSD) from a list of RSDs of a selected URSP rule to be matched with a PDN connection. If there is a “PDU session pair ID type” and/or “RSN type” route selection descriptor components in an RSD, such RSD components are intended for a redundant PDU session, which is not supported in EPS. Therefore, the UE ignores the specific RSD components and continues to evaluate the RSD with the remaining RSD components.

Abstract: The present invention provides a differential to single-ended converter including a first input node, a second input node, an operational amplifier and a feedback circuit. The operational amplifier has a first terminal and a second terminal, wherein the first terminal of the operational amplifier receives a first signal from the first input terminal, and the second terminal of the operational amplifier receives a second signal from the second input terminal. The feedback circuit is configured to receive an output signal of the operational amplifier and generate a first feedback signal to the first terminal of the operational amplifier to reduce a swing of the first signal, and generate a second feedback signal to the second terminal of the operational amplifier to balance noises induced by the feedback circuit and inputted to the first terminal and the second terminal.

Abstract: A method of supporting IMS signaling over EPS bearer or QoS flow upon inter-system change between EPS and 5GS is proposed. When inter-system change from 5GS to EPS occurs, a PDU session is converted to a PDN connection having multiple EPS bearers. The EPS bearer mapped from the QoS flow that is used for IMS signaling in 5GS is the EPS bearer for IMS signaling in EPS. When inter-system change from EPS to 5GS occurs, a PDN connection is converted to a PDU session having multiple QoS flows. The QoS flow that is associated with the default QoS rule is the QoS flow for IMS signaling in 5GS, regardless of which EPS bearer is used for IMS signaling in EPS.

Abstract: A method of defining ATtention (AT) commands for supporting Service and Session Continuity (SSC) mode 2 and SSC mode 3 of 5G Protocol Data Unit (PDU) session operations is proposed. The AT command can be a notification of an unsolicited result code +CGEV: NW PDN DEACT, +CGEV: NW MODIFY, or +CGEV: ME PDN ACT, or a configuration command +CGDCONT with additional 5G parameters. Additional 5G parameters include an SSC, an old CID, a change reason and a PDU lifetime for the purpose of communicating information regarding the request of PDU session anchor relocation.
