    摘要: This disclosure generally relates performing UE authentication and registration with the core network, and in particular, to supporting secure interactions between the UE and the target AMF when the UE is re-allocated to the target AMR During a UE registration procedure, the initial AMF generate a 5G-GUTI for the UE and retrieves a candidate AMF list. The initial AMF sends the generated 5G-GUTI (or 5G-S-TMSI), the candidate AMF list, and a full registration request message to the (R)AN for storage and subsequent use. The initial AMF, once determines an AMF re-allocation is needed, instruct the UE to re-start the registration procedure with the core network, by using the generated 5G-GUTI. The (R)AN selects the target AMF, and forward the stored full registration request message to the target AMF to complete the registration.

    摘要: Methods, apparatus, and systems for enabling an application function to influence access traffic steering, switching, splitting control are described. In one example aspect, a wireless communication method includes transmitting a request from an application function to a network function to enable a creation or an update of a policy or a rule for traffic routing. The request includes one or more parameters indicating traffic routing information for one or more user devices. The one or more parameters comprise at least an access type preference for the one or more user devices. The method also includes receiving a response from the network function indicating the creation or the update of the policy or the rule for traffic routing.

    摘要: Methods, apparatus and systems for backward compatible multi-access protocol data unit session (PDU) registration and deregistration are described. One method of digital communication includes establishing, by a session management function operating in a communication network, a PDU session for a wireless device and transmitting, upon successfully establishing the PDU session, a registration request to a network-side function to register a context of a PDU session of the wireless device with the network-side function, wherein the registration request identifies a set of session management functions that includes the session management function.

    摘要: A communication network supports multiple accesses by a wireless communication device in one implementation as follows. After a PDU session is established via a first access (e.g., via 3GPP access), an SMF (such as an hSMF) receives notification that the wireless communication device is registered over a second access (such as an untrusted non-3GPP access). The SMF establishes new QoS flows in the second access by sending a message to the AMF currently service the wireless communication device (including QoS information of the new QoS flow and information that these QoS flows are associated with the second access). The SMF also sends QoS rules of the new QoS flows to the wireless communication device via the first access.

    摘要: A wireless communication method for use in a network entity is disclosed. The method comprises receiving, from a wireless terminal, an indicator associated with a capability of supporting at least one method of interacting with an external network for a packet data connection authentication and/or authorization of the external network, and performing a procedure based on the indicator, wherein the procedure is associated with establishing a packet data network connectivity in a second network.

    摘要: Methods, apparatus, and systems that can be implemented to associate User Datagram Protocol (UDP) based connection identifiers with appropriate Quality of Service (QoS) flows are disclosed to enable Access Traffic Steering, Switching and Splitting functionality at lower layers and to allow accurate measurements of Round-Trip Time for all traffic on a session. In one example aspect, a wireless communication method includes determining, by one or more nodes in a core network for a session that comprises at least one QoS flow, at least two identifiers identifying two connections associated with the at least one QoS flow. The two connections are established according to a UDP based protocol. The method also includes establishing, by the one or more nodes in the core network, a mapping between the at least two connection identifiers and the at least one QoS flow.

    摘要: Disclosed are methods, systems and devices for selecting non-3GPP access nodes to support IMS services to 5G core networks. One example method for enabling identification of IMS support in a candidate non-3GPP node or network includes transmitting configuration information that includes an indicator of IMS (Internet Protocol (IP) Multimedia Subsystem) voice services support by an access node in a second network, where the indicator corresponds to an ability of the access node in the second network to support IMS voice services. Another method includes receiving configuration information comprising an indicator of IMS voice services support by an access node in a second network, and selectively accessing the IMS voice services in the second network through the access node based on the indicator.
