Abstract: Selecting a serving session control node in an Internet Protocol, IP, Multimedia Subsystem, IMS, telecommunication network, for a User Equipment.

Abstract: A UE is assigned a first server for session control of the session. The first IMS node sends a request to a subscriber server associated with the UE. The request requests assistance data for selecting a second server to be assigned to the UE for the session control. The first IMS node selects a second server to be assigned to the UE for session control, based on the requested assistance data. The first IMS node sends an invitation to the selected second server. The invitation includes an indication indicating that the selected second server is selected to replace the first server. The indication triggers the selected second server, to indicate to the subscriber server to register the address of the selected second server in the subscriber server, to replace the first server in being assigned to the UE for the session control.

Abstract: An authentication server (16) in a home network (18) of a wireless device (10) receives, from a network node (14), a request (20) for authentication data (22) based on which to authenticate the wireless device (10). The request (20) indicates a serving network (12) on which the authentication data (22) is to be based. The authentication server (16) checks whether or not the network node (14) is authorized to request authentication data (22) that is based on the indicated serving network (12).

Abstract: A method performed by performed by an exposure node having a first identity in a first network domain in a telecommunications network is provided. The method includes initiating a request towards a first network node for a subscription to an event of a communication device. The request includes subscription information for a common network exposure in at least two network domains. The method further includes receiving a response from the first network node. The response includes at least one of: a first confirmation that the event will be reported to the exposure node for a second network domain for the common network exposure and a second confirmation that the event will be reported to the exposure node for the first network domain. The second confirmation omits an indication of the common network exposure. Methods performed by a first network node are also provided.

Abstract: Embodiments described herein relate to methods and apparatuses for registering one or more services that a producer network function is capable of providing at a network repository function and allowing for the access of those services by consumer network functions. A method in a producer network function comprises transmitting a registration request to the NRF, wherein the registration request comprises registration information comprising: an indication of the one or more services; and an indication of resources and operations associated with each resource of the one or more services that are allowed per network function consumer type.

Abstract: A method of registering a User Equipment, UE, in a communication network, said method comprising the steps of receiving, by a control node in said core network, from an access network, a registration request message for registering a UE in said communication network, transmitting, by said control node, to a subscriber node in said communication network, a subscription request message, wherein said subscription request message requests subscription information for said UE and comprises an identification of a type of said access network, AN, via which said UE registration request message is received and an identification of a Radio Access Technology, RAT, used by said UE for connecting to said access network, receiving, by said control node, from said subscriber node, a subscription response message comprising said subscription information for said UE based on said AN and said RAT and transmitting, by said control node, to said UE, a registration complete message for indicating that said UE has registered in th

Abstract: A method of initiating a Packet Data Unit, PDU, session between an User Equipment, UE, and a Data Network Name, DNN, in a telecommunication network, said method comprising the steps of; receiving, by an Access & Mobility Function, AMF, a registration request for an UE for registering said UE in said telecommunication network, retrieving, by said AMF, from an Unified Data Management, UDM, node, one or more DNNs to which PDU sessions are expected to be established by said UE in said telecommunication network, and wherein said step of retrieving is triggered by said receiving of said registration request, instructing, by said AMF, said UE to initiate said one or more PDU sessions between said UE and said one or more DNNs. Complementary methods and Devices for performing a method according to the invention are also presented herein.

Abstract: Embodiments herein relate to a 3rd Generation Partnership Project, 3GPP, infrastructure node, a method in the 3GPP infrastructure node, 3GPP Access, Authorization, and Accounting, AAA server, a method in the 3GPP AAA server, a Home Subscriber Server, HSS and a method in the HSS. More particularly the embodiments herein relate to handling a UE requesting access to a service via an untrusted non-3GPP network. According to a first aspect, a method performed by a 3GPP node for handling a UE, requesting access to a service via an untrusted non-3GPP network is provided. The method comprises checking if trusted 3GPP network location information associated with the UE is available to the 3GPP node from a subscriber database or if the available trusted 3GPP network location information is obsolete.

Abstract: The invention relates to a PCS-server of a personal communication system providing personal telephone numbers for PCS subscribers. A PCS subscriber can send a handling message to the PCS-server and can form a specific handling of one or more destination profiles stored in a destination profile memory. The specific handling relates to the specific selection and activation/deactivation or switching between specific destination profiles or to the setting of specific call distribution criteria in the destination profiles. The call distribution criteria relate to origin parameter teleservice-type parameters, busy option parameters and number of call parameters. The PCS subscriber can therefore flexibly configure and use the destination profiles allocated to his personal telephone number. Based on the selected call distribution criteria a flexible delivery of the calls by using the so-set destination profiles is possible.
