Embodiments described herein provide methods and apparatus for configuring a service based architecture for discovery of a Network Function, NF. A method in a Network Function Discovery Orchestration includes configuring, in a domain name system, DNS, a first DNS entry associating a first domain name of the NF with at least one NF Internet Protocol, IP, address of the NF, and a second DNS entry associating the first domain name with at least one edge security node IP address of an edge security node in the first PLMN, wherein, the first DNS entry is for use in resolving requests for the NF which originate from within the first PLMN, and the second DNS entry is for use in resolving requests for the NF which originate from outside the first PLMN. Further methods and apparatus in a Network Repository Function, a Domain Name System and an edge security node are also provided.

Systems and methods are provided to support hypernumber portability for a hypernumber number corresponding to an electronic device. The electronic device may include an installed application to facilitate hypernumber portability. To this end, when the electronic devices connects to a wireless network, the electronic device may request a vehicle identification. If the wireless network is a vehicle-based network, the electronic device may receive the vehicle identification from an on-board node. When the received vehicle identification indicates that the electronic device has changed locations, the electronic device may communicate with a hypernumber database and/or a hypernumber server to update a dynamic phonebook. As a result, as the electronic device traverses a transport network, the dynamic phonebook may maintain updated location and call routing information for the electronic device.

A method for an interconnection functionality between a first mobile communication network and a second mobile communication network includes: associating or assigning private identifier information to specific public land mobile network (PLMN) identifier information related to the second mobile communication network; and in respect of signalling messages and/or data traffic packets that are to be routed or to be addressed or to be processed, providing for or supporting, by a network identifier and number translating functionality, a replacement and/or a translation, in both directions, between the private identifier information and the specific PLMN identifier information related to the second mobile communication network.

Various communication systems may benefit from suitable interworking. For example, certain fifth generation short message service systems may benefit from interworking with long term evolution short message service deployments in a visited public land mobile network. A method can include receiving, at a network element, an attach request from a user equipment. The method can also include using an internal policy to find a short message service function that resides at the network element. The method can further include using an address of the short message service function for providing short message service to the user equipment.
