The present disclosure relates to an enhanced session model capable of managing the configuration and the usage of a single packet data unit session, which is an association between a user equipment and a packet data network entity and is composed of multiple transmission bearers between the access network and the core network. The latter comprises a session type manager entity adapted to control the connectivity of these transmission bearers whose assignment is either individual or shared, multiple user plane function entities, a session type database and a control plane function entity. The latter can be functionally separate from the session type manager entity or extended with its functionalities. The user equipment and the user plane function entities are individually extended with the functionalities of, respectively, a user session type extension entity and user plane session type extension entities, which all comprise a respective mapping table dedicated to the assignment.

System and method for enhanced session management in nextgen mobile core networks

The present disclosure relates to network slicing, in particular, in 5G networks systems. The disclosure is concerned with network slice enablement for (vertical) applications. Thus, an entity for inter-operation between a network system and at least one application is provided. The entity provides a request to the network system, for selection and/or adjustment of a network slice instance (NSI) providing one or more services to the at least one application. The request comprises a set of requirements for the at least one application and/or the one or more services. The set of requirements comprises a required configuration or adaption of at least one NSI related parameter. The entity further receives a response to the request from the network system. The response indicates a decision of the network system regarding the selection and/or adjustment of the NSI.

Entity and method for network slice enablement for a vertical application

The disclosure relates to a method for operating a network function, NF1, of a first network slice, NSI-2, wherein the method comprises establishing an end-to-end path from NF1 of NSI-2 to a network function, NF2, of a second network slice, NSI-1. Moreover, the disclosure relates to a corresponding communication network.

Inter-slice sharing in 5G core networks

The disclosure relates to a mobile device configured to receive from a network a notification of a predicted change of a Quality-of-Service, QoS related to a local end-to-end data communication path; and configured to provide a report to the network, the report comprising at least one of the following information: location information, application layer information, mobile device status information, experienced QoS at mobile device side, radio channel conditions. The disclosure further relates to a network device configured to transceive communication data via a communication path, in particular a local end-to-end data communication path between a mobile device and another mobile device, based on a Quality-of-Service, QoS, requirement for the communication path; and configured to notify the mobile device about a predicted change of the QoS related to the communication path.

Techniques for notifying a quality of service change

The present application relates to a mobile core network (MCN) supporting end-to-end (E2E) network slicing, which comprises a controlling entity (CA_NF), one or more network function (NF) entities extended with functionalities (CA-NFExt), a network management entity (OSS) extended with functionalities (CA_OSSExt), and a coordination entity (CA_CF). The CA_NF communicates with the CA_OSSExt through the CA_CF using interfaces (If-CA_MP and If-CAC_OSS), and with the CA-NFExts using a respective interface (If-CA_NF) and/or other NFs interfaces. Based on information received from the OSS and the NF entities, the CA_NF generates a context with a certain type, sends, based on the generated context, context-related information towards entities impacted by the generated context amongst the NF entities and the OSS, and blocks, for a period of time, a transmission of any generated context towards the NF entities upon receiving, from the OSS, a notification message once the OSS decides to enforce a change.

Method for using context awareness for the coordination of management and mobile network service operation planes

A configuration module allows for the establishment of a local end-to-end (E2E) path connecting at least one source node and at least one target node via at least one radio access network (RAN) node. The configuration module is configured to select data radio bearers (DRBs) per quality of service (QoS) flow based on inter-node information from the at least one source node, the at least one target node, the at least one RAN node and all other nodes involved in establishing the local E2E path, and is also configured to initiate, after selecting the DRBs per QoS flow, a radio resource communication connection configuration using an identification of the local E2E path to be established. Thereby, a localized traffic between the at least one source node and the at least one target node can be exchanged with QoS guarantees.

Apparatus for V2X-oriented local E2E path establishment and QoS control

A network slice programming and management system is provided, for slicing a network to multiple groups of logical network slices composed of a collection of logical network functions, each dedicated to supporting a specific respective use for subscribers of the slice. The system comprises of a programming interface configured to receive commands for creation and/or configuration of network slice design comprising the constraints and requirements defining an architecture of logical network functions that when deployed form a network slice of a network, the commands include selection of at least one network function and a definition of an interaction of the selected at least one network function with other network functions.

System and method for programming and/or management of core network slices

The present disclosure relates to a slice monitor for monitoring slices programmed by a slice owner and deployed by an orchestrator in the control and data planes of a communication network. The slice monitor comprises multiple databases containing different types of information, selects the probes to monitor each slice in the control plane or the data plane and instantiates the selected probes as well as a single-slice monitoring device specific to each slice. For optimization, the slice monitor configures the content of its databases by communicating through multiple interfaces with different actors such as the slice owner, the owner of the orchestrator and the owner of itself. Using alarm handlers and a reconfiguration engine, the slice monitor together with the single-slice monitoring device can detect and compensate for possible violations in the service-level agreement by reconfiguring the slice. If the compensation fails, the slice monitor requests the orchestrator for reconfiguration.

Systems and methods for monitoring network slices using probes

The application provides a switch device and a software defined network (SDN) controller. The switch device includes a storage unit configured to store control flow entries, each control flow entry comprises at least one service field associated with at least one processing action, a receiver configured to receive a data plane packet, and a transmitter configured to transmit, to the SDN controller, a packet-in message, and a processor configured to determine whether at least one information field of the data plane packet or of the packet-in message matches the at least one service field of a control flow entry, and instruct the transmitter to transmit the packet-in message according to the processing action associated with the matched service field, if the at least one information field matches the at least one service field.

Software defined networking system for distinguishing packet-in messages

A set of functions, which comprises one or more access function and at least one network function, is provided in a telecommunication network. The telecommunication network is configured to provide compositions of functions based on the access function and the network function. Each composition of functions is uniquely identified by an identifier. The telecommunication network is further configured to provide to a terminal equipment one or more composition of functions based on the access function and the network function. The telecommunication network is further configured to make available the identifier of each composition of functions to the terminal equipment.
