Abstract: A method for network function discovery in a communication network is provided. The method includes receiving a discovery request from a first network function NF to request one or more NF instance of a first group type for a first subscriber. The discovery request may include a first group type identifier of the first group type. The method may further include determining one or more group identifier for one or more groups of NF instances managing the first subscriber. The one or more groups of NF instances are of the first group type and one or more other group types. The method may further include sending a discovery response to the first network function, including the one or more group identifiers and addressing information to reach the one or more groups of NF instances.

Abstract: A method is described for handling of connections between a client (200) and a server (214) via a communication network. A connection (206) is established over a first access point (202) which is associated with the server (214). At least one further access point (204) associated with the server is defined. A failure of the connection (206) over the first access point (202) is detected and a second connection (208) between the client (200) and the server (214) is established over the further access point (204). A third connection (212) between the client (200) and the server (214) over the first access point (202) is further established. The establishment of the third connection (212) is executed with a delay compared to the establishment of the second connection (208).
