摘要： 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.

摘要： A communication method and a communication system. The method may include: A first network device generates a node identifier, where the node identifier includes a global part and a local part, and the global part is determined based on geographical location information of a region covered by a second network device in which a node is located, for example, the second network device may be a device in mobile edge computing (MEC), and the local part is determined based on identity information of a terminal device associated with the node. The first network device sends the node identifier to the terminal device. In embodiments of this application, the geographical location information is introduced into the node identifier, so that a node that is identified nearby in space can also be short-distance in a physical network, thereby reducing an end-to-end latency.

摘要： 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.

摘要： 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.

摘要： 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.
