Abstract: Aspects described herein relate to various methods, systems and apparatuses that can be used to configure and manage a network slice based on billing rate information. By selecting a network slice based on billing rate information, the system may further be able to respond to billing rate changes by reselecting network slices. For example, changes in the usage of the network slice or the usage of the overall network infrastructure may cause a change to a billing rate associated with the network slice. These aspects, and others described herein, may result in improved network performance by, for example, offloading extra usage from an overloaded network slice to a network slice that is currently less used.

Abstract: Systems, methods, and software for performing online charging in next generation networks. In one embodiment, a Mobile Edge Computing (MEC) server is implemented at a Radio Access Network (RAN) of a next generation network. The MEC server hosts a plurality of edge applications provisioned to provide MEC services for a session. The MEC server communicates with a Session Management Function (SMF) of the next generation network to acquire a quota of service units for the session. The MEC server then manages the quota by allocating slices of the quota to the edge applications, and transmitting messages to the edge applications indicating the slices allocated to the edge applications.

Abstract: Systems, methods, and software for sharing resources of an air interface. In one embodiment, an access network element communicates with a plurality of devices over an air interface. The access network element identifies a resource sharing window having an MTC-On interval where MTC is allowed, and having an MTC-Off interval where MTC is prohibited. Between a threshold time and an end of the MTC-Off interval, the access network element selects an adjusted Modulation and Coding Scheme (MCS) for a legacy device of the plurality of devices that is lower than a standard MCS for the legacy device selected based on channel quality information for the legacy device, allocates a set of the MTC radio resources to the legacy device, and schedules a non-MTC transmission for the legacy device on the set of the MTC radio resources based on the adjusted MCS.

Abstract: Systems, methods, and software for controlling Quality of Service (QoS) selection in Mobile Edge Computing (MEC) services. In one embodiment, a MEC server is at a Radio Access Network (RAN), and implements edge applications that provide the MEC services. The MEC server queries a core network for a QoS policy for a mobile device that indicates QoS profile options for the mobile device, and receives the QoS policy from the core network. The MEC server monitors for a triggering event that triggers selection of a QoS profile, selects the QoS profile from the QoS profile options for a user plane connection established for a MEC service between the mobile device and an edge application in response to the triggering event, and provides a QoS profile identifier for the QoS profile to a base station in the RAN to enforce the QoS profile on the user plane connection.

Abstract: Systems, methods, and software for handling random access procedures. In one embodiment, an access network element that stores an MTC reservation pattern that defines at least one MTC-On interval where MTC is allowed, and defines at least one MTC-Off interval where MTC is prohibited. During an MTC-On interval, the access network element receives preambles for random access procedures from MTC devices, and performs the random access procedures for the MTC devices in response to the preambles. The access network element detects a transition from the MTC-On interval to a next MTC-Off interval, and determines whether the random access procedures for the MTC devices will complete before the transition. If not, the access network element modifies the MTC reservation pattern to expedite completion of the random access procedures.

Abstract: Embodiments of the present disclosure relate to for controlling D2D routing. A first device generates proximity information for a D2D connection group. The first device obtains information concerning a second device in the group. The first device generates a D2D route policy for at least one application on the second device, based on the generated proximity information, the obtained information concerning the second device and route selection criteria for the group, the policy at least indicating the route selection criteria and D2D paths satisfying the route selection criteria. The first device sends the D2D route policy for routing traffic of the at least one application in the group by the second device.

Abstract: Systems and methods for sharing radio resources on an air interface. One embodiment comprises an access network element (e.g., base station) that stores a plurality of sharing patterns each comprising a different mapping of the radio resources on a physical layer of the air interface between Machine-Type Communications (MTC) and non-MTC. The access network element identifies a resource sharing window, receives input indicating conditions in the access network, selects a sharing pattern from the plurality of sharing patterns in the pattern database for the resource sharing window based on the conditions in the access network, schedules MTC transmissions on the air interface at a beginning of the resource sharing window based on the sharing pattern, and schedules non-MTC transmissions on the air interface at the beginning of the resource sharing window based on the sharing pattern.

Abstract: Systems, methods, and software for performing online charging in next generation networks. In one embodiment, a Session Management Function (SMF) of a next generation network implements a Charging Trigger Function (CTF) that directly interfaces with an Online Charging System (OCS). The CTF transmits a charging request to the OCS requesting a quota of service units for the SMF, and receives a charging response from the OCS indicating the quota of service units granted to the SMF by the OCS. The CTF then manages the quota by allocating slices of the quota to User Plane Functions (UPF) implemented in a user plane of the next generation network.

Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for terminal devices influenced network slice selection. According to embodiments of the present disclosure, a new terminal device influenced network slice selection is proposed. The NRF updates the application profile for the terminal device based on the change of the applications on the terminal device. The NRF may notify the PCF about the application profile and the PCF generates the route policy for the application on the terminal device. In this way, problems regarding the affected terminal devices of application influenced network slice selection are solved.
