摘要： Methods and apparatus are provided for a voice over LTE system to shorten the call set up time. In one novel aspect, the mobile origination (MO) UE starts the UE-initiated dedicated resource allocation before receiving any responses from the remote UE. In another embodiment, the mobile termination (MT) UE starts the UE-initiated dedicated resource allocation upon receiving the INVITE from the remote UE. In one embodiment, the UE adjusts the timeout value based on the PLMN information in its PLMN database. The timeout value can be set to be zero if early reservation is allowed. Upon timer expires, the UE starts UE-initiated dedicated resource allocation. In one novel aspect, the MO UE retrieves the codec information of a remote UE from its peer profile information database and uses a matching codec in its INVITE message. In another embodiment, the MT MO includes the SDP answer in its 180 RINGING message.

摘要： A PDU session status information element (IE) is used to bi-directionally synchronize the state of a multi-access (MA) Protocol data unit (PDU) session between UE and NW. In the downlink, the PDU session status IE is included in a 5GMM message sent from NW to UE over an access type, and it indicates the user plane resources are NOT established at NW side on the access type the 5GMM message is sent over. For MA PDU sessions having user plane resources established in the UE side only on the access type the 5GMM message is sent over, the UE performs a local release of those MA PDU sessions. For MA PDU sessions having user plane resources established in the UE side on both access types, the UE performs a local release on the user plane resources on the access type the 5GMM message is sent over.

摘要： A method of handling multi-access (MA) Protocol data unit (PDU) session handover is proposed. A UE and network can support Access Traffic Steering Switching and Splitting (ATSSS) functionalities to distribute traffic over 3GPP access and non-3GPP access for the established MA PDU session. An ATSSS-Supported UE first establishes a MA PDU Session on both 3GPP and non-3GPP access in a currently registered PLMN which is an ATSSS-Supported network. The UE then moves from the ATSSS-Supported network to an ATSSS-not-Supported network and finally reaches another ATSSS-Supported network. In one novel aspect, a solution is provided on how to handle the ongoing MA PDU Session with two accesses under handover scenarios between ATSSS-Supported and ATSSS-not-Supported networks. Furthermore, if the ongoing MA PDU Session cannot handover, a solution is provided on how to handle the MA PDU Session.

摘要： A method can include receiving a non-access stratum (NAS) message for establishing or modifying a protocol data unit (PDU) session at a user equipment (UE) from a core network, determining whether there is a quality of service (QoS) flow description resulting from the establishment or modification of the PDU session that is associated with a guaranteed bit rate (GBR) QoS flow of the PDU session, and invalid, and when it is determined that there is the invalid QoS flow description associated with the GBR QoS flow of the PDU session, performing an error handling operation.

摘要： A method for synchronizing evolved packet system (EPS) bearer context status between a user equipment (UE) and a network can include locally deactivating an EPS bearer context of a packet data network (PDN) connection at the UE while the UE operates in S1 mode without notifying the network serving the UE, wherein interworking to a fifth generation system (5GS) is supported for the deactivated EPS bearer context, and upon inter-system change from S1 mode to N1 mode, including an EPS bearer context status information element (IE) in a registration request message indicating which EPS bearer contexts are active in the UE before the inter-system change.

摘要： Solutions for data network name (DNN) selection when user equipment (UE) route selection policy (URSP) rule is applied in evolved packet system (EPS) with respect to user equipment and network apparatus in mobile communications are described. An apparatus may start an application in an EPS network. The apparatus may select a URSP rule from one or more configured URSP rules by matching a traffic descriptor (TD) of the URSP rule with the application. The apparatus may determine whether a data network name (DNN) or access point name (APN) included in a route selection descriptor (RSD) is a local area data network (LADN) DNN or APN. The apparatus may skip the RSD in an event that the DNN or APN is the LADN DNN or APN. The apparatus may evaluate a next RSD or a next URSP rule in case that the next RSD or the next URSP rule is available.

摘要： A method of handling invalid PDU session during handover procedure between non-3GPP access and 3GPP access in a mobile communication network is proposed. A UE establishes a PDU session over a first RAT, and then tries to handover the PDU session from the first RAT to a second RAT. However, at the network side, the PDU session over the first RAT does not exist anymore and the network considers the PDU session to be invalid. The network thus sends a PDU session establishment reject message back to the UE, with a 5GSM status message cause value #54 indicating “PDU session does not exist”. At the UE side, the PDU session over the first RAT is still valid (e.g., not inactive). In order to resynchronize with the network, the UE performs a PDU session release procedure to release the PDU session over the first RAT.

摘要： 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.

For example, the apparatus can include a non-volatile memory, receiving circuitry, transmitting circuitry and processing circuitry. The receiving circuitry can be configured to receive a configuration update command message and a registration accept message, each of which includes a CAG information list IE containing a CAG information list. The transmitting circuitry can be configured to transmit a configuration update complete message and a registration request message. The processing circuitry can be configured to store the CAG information list of the CAG information list IE in the non-volatile memory, and select a public land mobile network based on the CAG information list stored in the non-volatile memory.

摘要： Aspects of the disclosure provide apparatuses and methods for wireless communications. One apparatus includes processing circuitry that selects a non-default and unevaluated URSP rule as an evaluating URSP rule. The URSP rule includes a traffic descriptor matching an application triggered by the apparatus. The processing circuitry selects a first unevaluated RSD of the evaluating URSP rule as an evaluating RSD, and determines whether the evaluating RSD includes at least one of a non-supported PDU session type, a non-supported SSC mode, and a non-supported S-NSSAI. When the evaluating RSD is determined to include at least one of the non-supported PDU session type, the non-supported SSC mode, and the non-supported S-NSSAI, the processing circuitry determines whether the evaluating URSP rule includes a second unevaluated RSD. The processing circuitry selects the second unevaluated RSD as the evaluating RSD when the evaluating URSP rule is determined to include the second unevaluated RSD.
