The present disclosure relates to simultaneous operation of Wi-Fi access points in a super cell mode and a standalone mode and controlling connectivity of end terminals thereto. In one aspect, a method includes receiving a configuration for a group of access points operating within a network, the configuration allowing each access point of the group to operate in a super cell mode over a shared frequency channel and a standalone mode over a non-shared frequency channel. The method further includes determining, for an end terminal, whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel based on a network policy to yield a determination; and controlling connectivity of the end terminal to at least one access point of the group of access points over the shared frequency channel or the non-shared frequency channel based on the determination.

Techniques and mechanisms for use in facilitating home network assisted concurrent access to network slices in multiple visited public land mobile networks (VPLMNs) are described. A control plane (CP) function for mobility management may receive, from a UE (e.g., configured without dual connectivity), a message which indicates a registration request for registration using a first network slice and a second network slice. The CP function may manage registration for the UE in response to the registration request. The CP function may receive, from the UE, a message which indicates a request for establishing a protocol data unit (PDU) session using the second network slice which is not supported or available in the first VPLMN. The CP function may forward the request for establishing the PDU session to an application function (AF) for managing establishment of the PDU session for the UE using the second network slice in a second VPLMN.

In one aspect, a method of IP obfuscation of a user device includes receiving, over an Extendible Authentication Protocol (EAP) session between a user device and a network access point, location preferences of the user device, generating, based on the location preferences or a network policy, a geohash for the user device, identifying, for the user device, an IP anchor, sending, over the EAP session, the geohash to the user device, and receiving, from the user device, network traffic, wherein the network access point utilizes the geohash and the IP anchor to route the network traffic for the user device and obfuscate IP address of the user device from third-party access.

Technique for eliminating ingress-proxy in the multi-relay approach for privacy

The present disclosure is directed to systems and techniques for providing service continuity for User Equipment (UE) services associated with certain network slices. In one example, the systems and techniques can receive a registration request from a UE, wherein the registration request includes a requested slice, and determine a current network location of the UE. In response to determining that the current network location of the UE does not support the requested slice, one or more additional network locations that support the requested slice can be identified. Location information associated with the one or more additional network locations can be identified and a registration response message can be transmitted to the UE, wherein the registration response message includes location information of an one or more additional Tracking Area Identities (TAIs) or additional Registration Areas (RAs) that support the requested slice.
