Abstract: A disclosed method is performed at a first node providing mobile services to a user equipment (UE) over an access network (AN). The first node receives a setup request from UE to be connected to a network over an AN. The first node then sends a fully qualified domain name (FQDN) of the first node over a first interface terminated by the first node to an access and mobility management function (AMF). The first node further triggers the AMF to transmit a session establishment request to a session management function (SMF) including the FQDN of the first node, where in response, the SMF selects second node(s) in the network collocated with the first node based at least in part on a topology match of FQDNs. The first node then provides UE access to the network over the AN through the collocated first node and the node(s).

Abstract: Techniques are presented that ensure Quality of Service (QoS) for Wi-Fi® calling and other Internet Media Services (IMS) when a user connects from a carrier-operated public Wi-Fi network to an IMS. A first packet including a domain name system (DNS) request received from a wireless mobile device via an access point is intercepted at a networking device. A network address of a collocated gateway device associated with the networking device is sent to the wireless mobile device in response to the DNS request. A second packet is received from the wireless mobile device including the network address of the collocated gateway to establish a network communication via the collocated gateway device. First QoS parameters associated with the network communication are received from the collocated gateway device and a notification message is sent to the access point, the notification message including the first QoS parameters.

Abstract: One or more controllers of a control plane (CP) entity for use in a mobile network (e.g. a mobility management entity or “MME”) may be configured to receive or obtain an indication which indicates whether an eNodeB (eNB) is configured to support Dual Connectivity with New Radio (DCNR), for a 5G Non-Standalone (NSA) architecture deployment. The one or more controllers may be further configured to select, based on the indication, one of a plurality of serving gateways (SGWs) for a session of a user equipment (UE) served by the eNB. Additional information may be used as a basis for the SGW selection, including UE capability and UE subscription data. For example, when the indication indicates that the eNB is configured to support DCNR and the UE capability and subscription data indicate 5G capability, a 5G-capable SGW may be selected but otherwise a legacy (non-5G) SGW may be selected.

Abstract: Presented herein are techniques for detecting establishment of a bearer associated with a communication session offloaded from a mobile carrier network to a wireless local area network, such as a Wi-Fi® network, and sending, from the mobile carrier network to the wireless local area network, an indication of a level of quality of service (QoS) to be applied to a segment of the communication session that is conveyed by the wireless local area network. The indication of the level of QoS may be passed via a network controller.
