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.

Common event exposure in network domains

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.

Registering and requesting services in a service based architecture

Selecting a serving session control node in an Internet Protocol, IP, Multimedia Subsystem, IMS, telecommunication network, for a User Equipment. The method includes receiving, by an interrogating session control node, a Session Initiation Protocol, SIP register message for registering said UE in said IMS telecommunication network, the SIP register message has a UE capability feature mappable to a UE initiated server capability for the serving session control node, transmitting, by the interrogating session control node, to a Home Subscriber Server, a user authorization request message comprising the UE capability feature, receiving, by the interrogating session control node, from the Home Subscriber Server, a user authorization answer message including one or more UE initiated server capabilities for a serving session control node, selecting, by the interrogating session control node, a serving session control node based on the one or more received UE initiated server capabilities in the user authorization answer message.

Methods and apparatus for selecting a serving session control node in an internet protocol multimedia subsystem, IMS, telecommunication network for a user equipment

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 the communication network.

Methods and devices for supporting user equipment, UE, authorization based on the type of access network as well as based on the type of radio access technology, RAT

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.

Methods and devices for supporting network initiated PDU session establishment between an user equipment, UE, and a data network name, DNN, in a telecommunication network

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. If the trusted 3GPP network location information is unavailable or obsolete, the method comprises determining to use untrusted non-3GPP network location information previously received from the 3GPP AAA server or to derive the untrusted non-3GPP network location information at the 3GPP node. Still further, the method comprises determining if the UE is allowed or barred to access the service via the untrusted non-3GPP network based on the received or derived untrusted non-3GPP network location information. The embodiments herein, relate also to corresponding methods performed in an 3GPP Access, Authorization, and Accounting, AAA server, and a Home Subscriber Server, HSS, respectively. Further, the embodiments herein relate also to corresponding 3GPP infrastructure node, 3GPP AAA server, and HSS.

Methods and nodes for handling access to a service via an untrusted non-3GPP network

A method for restoring faulty subscriber-related data in an Evolved Packet System (EPS) network including a Home Subscriber Server (HSS) and a 3GPP AAA server, be characterized by comprising the following steps performed at the 3GPP AAA server: receiving an indicator from the HSS, the indicator identifying one or more subscribers having the faulty subscriber-related data stored in the HSS; and for an interaction with an access from a non-3GPP network, if the access corresponding to one of the identified subscribers, instructing the HSS to restore the faulty subscriber-related data for one or all of the identified subscribers.

HSS fault recovery for non-3GPP access

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.
