    摘要: A method for selecting a user plane function when a user equipment (UE) attaches to a wireless communication network may include determining a data throughput limit associated with the UE, identifying a first user plane function having a first data throughput capacity, and identifying a second user plane function having a second data throughput capacity, wherein the first throughput capacity is higher than the second throughput capacity. The method may further include selecting the first user plane function if the data throughput limit of the UE is above a predetermined threshold, selecting the second user plane function if the data throughput limit of the UE is below the predetermined threshold, and sending a session request to the selected first or second user plane function.

    摘要: A telecommunication network associated with a wireless telecommunication provider can be configured to select user-plane functions (UPFs) for a user equipment (UE) in a network, and the handover of subscriber sessions. According to some configurations, a nearest UPF to the UE can be picked to service the UE. Choosing the nearest UPF may reduce latency to the UE when sending and receiving packets through a cellular network, such as a 5G network. Subscriber sessions can be handed over across multiple UPFs based on mobility of the UE. Subscriber sessions may be anchored on UPFs located either on edge locations or centralized data centers. Because of mobility of subscribers from a first location (e.g., x) to a second location (e.g., y), a subscriber's session can be moved from one user plane node to another user plane node seamlessly.

    摘要: A system, e.g., associated with a telecommunications network, includes first and second registry devices. In some examples, the first registry device receives a registration message. The second registry device receives a query specifying a type (NFType) of a network function and forwards the query to the first registry device based at least in part on the NFType. The first registry device responds, and the second registry device forwards the response. In some examples, the query specifies a service class and the second registry device forwards the query based at least in part on the service class. In some examples, the first registry device sends an indication of the registration to the second registry device, and the second registry device responds to the query based at least in part on the received indication and on at least one of an NFType or a service class of the query.

    摘要: The disclosed system includes a first gateway of a first type configured to receive wireless packets from a core network node, and a second gateway of a second type colocated with the first gateway and configured to transmit at least a portion of the wireless packets to a network. The first gateway is configured with a first internet address that identifies the second gateway and a second internet address that identifies a third gateway of the second type. The first gateway is configured to transmit a first portion of the wireless packets to the second gateway based on the first internet address and transmit a second portion of the wireless packets to the third gateway based on the second internet address. The second gateway is configured with a third internet address that identifies the second gateway.

    摘要: Solutions for providing a data traffic session for a user equipment (UE) over a wireless network comprises: receiving, by a session management node (e.g., a session management function, SMF), for a packet routing node (e.g., a user plane function, UPF), an indication of supported interne protocol (IP) traffic type (e.g., IPv4 or IPv6), wherein the indication of supported IP traffic type indicates support for a first IP traffic type or support for a second IP traffic type; allocating, by the session management node, to the packet routing node, a set of IP addresses based on at least the indication of supported IP traffic types, wherein allocating the set of IP addresses comprises allocating only supported IP addresses and withholding allocation of unsupported IP addresses; and providing, to the UE, using an IP address of the set of IP addresses, the data traffic session through the packet routing node.
