Abstract: A method performed by an IP Multimedia Core Network Subsystem (IMS) node, for enabling management of events occurring in a network slice of a communication network that comprises partitioned sets of functionalities wherein each set of functionalities belongs to a dedicated network slice, and wherein a set of functionalities is separated from other sets of functionalities. The IMS node obtains, from a core network node responsible for policy control, an indication of a first action relating to a session established in the network slice, wherein said first indication comprises a first network slice identifier. The IMS node sends, to a managing node, a message indicating a second action to be performed in the managing node in response to the first action relating to the session established in the network slice, wherein the message comprises a second network slice identifier identifying the first network slice in which the first action occurred.

Abstract: The invention relates to a method for generating a digit map for a call setup, wherein leading digits of a call number are collected by a gateway and transmitted to a call control server where a call-specific digit map is generated by comparing the leading digits to a numbering plan.

Abstract: The combination of narrowband applications with broadband transport may be enabled with a tri-level nodal communications architecture including multiple call control nodes, multiple connection control nodes and one or more intermediates node for interworking between the call control nodes and connection control nodes, in which the intermediate node(s) are controlled by all of the call control nodes. In certain embodiment(s), the identity of the call control node is transmitted to the intermediate node with each message to differentiate between the multiple call control nodes. In addition, each resource (e.g., port) managed by the intermediate node has a call control node identity associated therewith. In further embodiments, a logical port is used to support connections between call control nodes sharing the same intermediate node. The logical port represents a logical E1 path between the two call control nodes.
