摘要： Systems, devices, and techniques described herein relate to migrating a communication session from a path including a stressed user plane function (UPF) to a path including a replacement UPF. A communication session may traverse a first path including the first UPF. After establishing the communication session, the first UPF may be determined to be stressed. In response, the communication session can be proactively migrated to a second path including a second UPF. According to various implementations, the existing communication session can be maintained during the migration, thereby substantially eliminating interruptions caused by the stressed first UPF.

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.

摘要： System and methods for efficient user plane function (UPF) selection are described. A mobile device (UE) may transmit a connection request to a 5G core network. The connection request can include an indication that the type of data to be serviced is IPv4-type traffic. The access management function (AMF) receives the request from a base station (e.g., gNodeB) and queries a network function repository function (NRF) for an identification of a session management function (SMF). The selected SMF queries a session management function datastore. If the SMF selected by the NRF is capable of IPV4 traffic, the identification of the SMF is returned to the AMF. If the SMF is not capable of IPV4 traffic, the identification of a capable SMF using the information received in the SMF status datastore is returned to the AMF through a 308 code. The mobile device is thereafter connected to the capable UPF.

摘要： System and methods for efficient serving gateway and packet data gateway selections are described. A mobile device may attempt transmit an attach request to a network requesting packet data services in a particle protocol. A control plane of a serving gateway may receive the attach request and determine a serving gateway user plane that is configured to operate in the specified protocol. The serving gateway control plane may then propagate the determined serving gateway user plane to a packet data network gateway control plane for selection of the serving gateway user plane and a corresponding packet data network gateway user plane for use in providing packet services to the mobile device.
