Abstract: Aspects describe renegotiation of quality of service parameters to resolve maximum bit rate mismatches and/or other quality of service parameter mismatching issues that might arise during an inter-radio access technology handover. At about the same time as a mobile device moves from a source network to a target network, the target network dynamically initiates a quality of service modification procedure. The quality of service modification procedure can help resolve the maximum bit rate mismatches and/or the other quality of service parameter mismatching issues.

Abstract: A system that incorporates the subject disclosure may include, for example, receive a subscription from an application server where the subscription identifies a session event and/or sub-events occurring in a communication session for which the application server requests user location information, provide subscription information based on the subscription to core network nodes of the mobile communications network, receive user location information from the core network nodes responsive to a detection of a triggering event corresponding to the session event of the subscription, and provide the user location information to an IP multimedia subsystem network for delivery to the application server. Other embodiments are disclosed.

Abstract: A wireless network for mobile communications has a connectionless framework using native internet protocol (IP). In this connectionless framework, packet routing may be based on user endpoint (UE) physical IP address, which is associated with the prefix of an associated access node (e.g. eNB). In addition to using the connectionless-IP framework for the traffic flow carried by one access point (e.g. eNB) at a time, advanced mobile call processing features, such as carrier aggregation and dual connectivity, are enhanced to leverage the packet-oriented connectionless radio access network and wireless core network architecture by using the SDN architecture and a wireless network specific software-defined network controller.

Abstract: Concepts and technologies disclosed herein are directed to an enhanced software-defined networking (“SDN”) controller to support ad-hoc radio access technologies (“RATs”). An SDN controller receives, from an ad-hoc radio access controller serving an ad-hoc radio access network (“RAN”), an attach request sent on behalf of a user equipment (“UE”) operating in communication with an ad-hoc RAT transceiver node. The attach request includes a physical IP address associated with the UE. The physical IP address includes an IP address sub-interface pre-fix broadcast to the UE by the ad-hoc RAT transceiver node combined with a physical address of the UE. In response to the attach request, the SDN controller can complete an attachment procedure for allowing the ad-hoc radio access controller to an SDN network. The SDN controller also can update one or more components operating within the SDN network to reflect how to reach the UE via the physical IP address.

Abstract: Network and/or application resources can be dynamically instantiated based on service attributes and/or network capabilities. In one aspect, a customized and/or localized core slice can be selected that can deliver the requested service with target performance parameters. According to an aspect, dynamic selection, control, and/or management reporting can be provided for core network slices. Moreover, optimal core network slice selection can be performed to reduce network transport costs and efficiently deliver various services using an optimal core slice that matches a service profile being requested by an end user and/or device.

Abstract: An SDN controller configures a network element as a service edge. The SDN controller configures a service flow associated with a service to receive a required service treatment. The SDN controller configures an entry point to add routing tags on a set of packets associated with the service. The set of packets are routed in accordance with the routing tags. The required service treatment is applied at the service edge and the tags are removed from the set of packets, which are then forwarded to the network.

Abstract: The described technology is generally directed towards a frequency-aware cellular communication network. A mobile device, or a radio access network (RAN) device at a base station in communication with the mobile device, can proactively notify a core network device regarding changes of a frequency band used for communications between the mobile device and the base station. The core network can use received notifications to adjust service provided to the mobile device.

Abstract: A method and apparatus for session management in a wireless network are disclosed. For example, a user endpoint (UE) device, sends a request for a session internet protocol (IP) address assignment using an interface IP address, configures the UE device with the session IP address, provides to a controller an association of the interface and session IP addresses, and receives packets addressed to the session IP address via an access network entity associated with the interface IP address. In one example, a controller receives an association of an interface IP address with a session IP address from an attached UE device, provides to a network node an update on a route to reach the session IP address through the interface IP address, identifies an active interface IP address to receive packets, and configures an open flow switch or router for routing the packets towards the active interface IP address.
