Embodiments described herein relate to methods and apparatus for obtaining and/or providing Home Subscriber Service, HSS, information. A method in a first service based architecture, SBI, capable Internet Protocol Multimedia Subsystem, IMS, entity includes: transmitting a discovery request to a network repository function, NRF; receiving a response comprising HSS information from the NRF; and transmitting at least a portion of the HSS information to a second SBI capable IMS entity.

Service based interface enabled home subscriber service selection

Apparatuses and methods for short message service (SMS) delivery are disclosed. In one embodiment, a method implemented in a data management (UDM) node includes receiving, by the UDM node, a registration request from a home subscriber server, HSS, node, the registration request being to register an Internet Protocol-Short Message-Gateway, IP-SM-GW, and the registration request comprising an address of the IP-SM-GW; and optionally, as a result of receiving the registration request comprising the address of the IP-SM-GW from the HSS node, determining message waiting data. In one embodiment, a method implemented in a HSS node includes receiving a registration request; and sending, to a unified data management, UDM, node, the registration request, the registration request being to register an Internet Protocol-Short Message-Gateway, IP-SM-GW, and the registration request comprising an address of the IP-SM-GW.

Support of short message service over internet protocol (SMSoIP) in 5G-only deployments

A method for supporting authentication of a User Equipment, UE, in an Internet Protocol, IP, Multimedia Subsystem, IMS, telecommunication network, by interfacing a Service Based Architecture, SBA, telecommunication network, the method including receiving, by a Unified Data Management, UDM, in the SBA telecommunication network, from a Session Management Function, SMF, in the SBA telecommunication network, binding information, wherein the binding information is used to identify the UE in the IMS telecommunication network; receiving, by the UDM in the SBA telecommunication network, from a Home Subscriber Server, in the IMS telecommunication network, a request for providing the binding information, and providing, by the UDM in the SBA telecommunication network, to the HSS in the IMS telecommunication network the binding information, thereby supporting authentication of the UE. Complementary methods and corresponding nodes are also presented herein.

Method for supporting authentication of a user equipment in an internet multimedia subsystem (IMS) communication network

Apparatuses and methods for short message service (SMS) delivery are disclosed. In one embodiment, a method implemented in a unified data management, UDM, node includes setting a short message service, SMS, function, SMSF, registration notification flag to detect an SMSF registration event associated with a user equipment, UE. In another embodiment, a method implemented in a home subscriber server, HSS, node includes sending a request to subscribe to a notification at a unified data management, UDM, node about a short message service, SMS, function, SMSF, registration event associated with a user equipment, UE.

Short message service (SMS) delivery

A method for discovering services in a telecommunication network provided by a network function, NF, in a Service Based Architecture, SBA, based telecommunication network, said method comprising the steps of receiving a discovery request, from a Network function, NF, consumer, for discovering an NF producer to interact with, wherein said discovery request comprises a Mobile Station International Subscriber Directory Number, MSISDN, associated with said NF consumer, transmitting to an address translate server, an address translate query, wherein said address translate query comprises said MSISDN, receiving an address translate response, wherein said address translate response comprises a Universal Resource Identifier, URI, and transmitting, to said NF, a discovery response, wherein said discovery response comprises an NF producer instance for interaction with said NF.

Method, and nodes, for discovering services in a telecommunication network provided by a network function, NF, in a service based architecture, SBA, based telecommunication network

A method is performed by a first front-end node, for supporting data communication. The first front-end node operates in a communications network comprising a pool of front-end nodes for providing access to a database. The pool of front-end nodes includes the first front-end node. The first front-end node receives, from a load balancer node, a first request for data from the database, from a client node. The first front-end node provides, to the client node, a first response to the received first request, the first response including a first indication indicating that the first front-end node is a preferred node for providing a subsequent response to a subsequent request for data from the client node. The subsequent response is allowed to originate from another front-end node in the pool of front-end nodes, different than the preferred node.
