Abstract: According to certain embodiments, a method and apparatus may include performing, by a first network entity, at least one benchmarking procedure of at least one network hop delay per at least one transmit resource towards at least one peer network node identified by at least one internet protocol destination address. The method and apparatus may further include deriving, by the first network entity, a second table, by, for each peer node associated with an internet protocol destination address, determining at least one existing configured mapping of at least one network instance into a transport resource Ti per internet protocol destination address. The method and apparatus may further include updating, by the first network entity, the first table and the second table for each internet protocol destination address and transmitting the updated second table to the second network entity.

Abstract: There are provided measures for enforcement of maximum number of admitted terminals per network slice. Such measures exemplarily comprise receiving a packet data connection related request concerning a network slice being configured with a maximum number of terminals to be admitted to said network slice, maintaining a counter indicative of a number of terminals admitted to said network slice based on said packet data connection related request, and transmitting a response to said packet data connection related request.

Abstract: A method, apparatus and computer program product are provided herein to provide service continuity between a Stand-alone Non-Public Network (SNPN) and a Public Land Mobile Network (PLMN). For example, a method is provided that comprises after determining that the user equipment (UE) with the first protocol data unit (PDU) session established in the first SNPN is or will be leaving the coverage area of the first SNPN, causing a request message to be transmitted to the UE, wherein the request message comprises a request to initiate a second PDU session establishment procedure towards a PLMN. The method also includes causing the UE to establish the second PDU session with an internet protocol anchor function of a user plane function in the PLMN via the first SNPN radio access network (RAN) or via the PLMN RAN, wherein the second PDU session is established prior to release of the first PDU session.

Abstract: A plurality of interworking functions, which provide interworking between a communication network acting as access network and another communication network, is associated with a plurality of network slices or non-public networks hosted by the other communication network. A user equipment performs connection (S301) to a communication network acting as access network, and selects (S303) an interworking function of the plurality of interworking functions based on information on a network slice or non-public network hosted by the other communication network, wherein the user equipment is associated with the network slice or non-public network.
