A method performed by an Internet protocol Multimedia System, IMS, node for handling categorization data associated to a first device in an incoming call invitation from the first device to a second device in a communications network is provided. The IMS node obtains () from the server node, a number of respective data delta. Each data delta is related to a respective device out of a number of devices at a respective subsequent point in time. The respective data delta comprises only categorization data that is updated compared to categorization data relating to a point in time that is earlier than the subsequent point in time. Upon receiving () from the first device, a call invitation to the second device, the IMS node enforces () a policy relating to categorizing the type of communication of the call, to establish a trust level associated with the first device. The enforcing is based on whether a data delta relating to the first device is obtained among the number of obtained data delta relating to the number of devices.

Telephony application server node, server node, and methods therein, in a communications network

A method performed by an Internet Protocol Multimedia Subsystem, IMS, node, for handling a setup of a session between a first User Equipment, UE, and a second UE, in a communications network is provided. The IMS node receives () a request to setup a session from the first UE to the second UE. The request indicates a privacy value which the first UE has requested to apply for the session. The IMS node sends () a request to a server node. The request comprises an identity of the first UE and the privacy value. The request requests the server node to analyse the reputation of the first UE based on the identity of the first UE and the privacy value. The IMS node receives () a response from the server node. The response indicates the analysed reputation of the first UE. The IMS node then decides () how to handle the session setup and session privacy, based on the analysed reputation of the first UE.

Internet protocol multimedia subsystem node, server node and methods in a communications network

Embodiments herein relate to a method performed by a first network node () in a wireless communications network (), for handling an addition of a participant to an ongoing call session for a first UE () handled by an IMS node (). The ongoing call session is a session between the first UE () and a second UE (). The first network node receives, from a second network node (), a request to add a participant to an ongoing call session for the first UE (). The first network node () obtains a list of one or more ongoing call sessions for the first user from the IMS node (), wherein the list comprises an identifier for identifying each of the one or more ongoing call sessions. The first network nodefurther sends, to the IMS node (), a request to add the participant to one of the one or more ongoing call sessions for the first UE (), wherein the request comprises the identifier for identifying the call session to which the participant is to be added and an identification of the participant to add to the ongoing call session. Embodiments herein further relate to methods performed by the second network node () and the IMS node ().

Network nodes and methods performed therein for handling call information for a user equipment

A method, by a first node, for handling provision of an IMS service. A communications network comprises a first slice handling a first IMS service, and a second slice handling a second IMS service. The first node obtains, from a second node at least one of a first and a second indication. The first indication is of a first routing service instance for a third node handling the first service in the first slice. The second indication is of a second routing service instance for a fourth node handling the second service in the second slice. The first node routes a request, to one of the nodes with one of the proviso that when the request is for the first service, the routing is based on the first indication, and when the request is for the second service, the routing is based on the second indication.

Embodiments herein relate to a method performed by a first network node () in a wireless communications network (), for handling media channels during an ongoing media session. The ongoing media session is a session comprising a first UE (), a second UE () and the first network node (). The first network node () obtains, from the first UE (), a voice instruction comprising a keyword for invoking a third party service within the media session. The first network node () further detects the keyword for invoking the third party service within the media session. The first network node () modifies, based on the detection of the keyword, a media channel between the first network node () and the second UE () to be silent. The first network node () further modifies, based on the detection of the keyword, a media channel between the first network node () and a third party network device () to be unsilent. Embodiments herein further relate to a method performed by the second network node (). The second network node obtains, from the first network node (), an indication that one or more services are requested from the third party network device (). The second network node further provides, to the first network node (), a request to modify the media channel for the second UE () to be silent.

Network nodes and methods performed therein for handling media channels during an ongoing media session

There is provided a method of operating a server of a network for managing user equipment registrations. The method comprises receiving () information indicative of whether user equipments are currently registered to a service, storing () the received information indicative of whether user equipments are currently registered to a service. The method also comprises receiving () a request associated with managing current registrations to services for one or more user equipments and initiating () an action to manage current registrations to services for one or more user equipments in accordance with the request.

User equipment registrations management

A network node for handling access to sharing media in a media session in an Over The Top (OTT) Digital Assistant (DA). The media shall be shared between a first participant A and a second participant B in a communications network. The first participant A has access to sharing media in the media session in the OTT DA. The network node receives a request for access from the OTT DA. The request for access relates to the first participant A requesting access for the second participant B to sharing media in the media session in the OTT DA. The network node forwards the request to an IP Multimedia Subsystem (IMS) node in the communications network, to trigger the IMS node to switch on the sharing of media in the media session in the OTT DA for the second participant B, when authorised by the participant B.

Network node, IP multimedia subsystem (IMS) node, over the top (OTT) digital assistant, and methods in a communications network

Embodiments herein relate to a method performed by an IMS node for handling data of a UE, in a communication network, wherein the communication network comprises partitioned sets of functionalities of one or more core networks wherein each set of functionalities belongs to a network slice. The IMS node receives, from the UE, a message for registering the UE to the IMS node, wherein the message comprises a slice indication indicating a network slice identity and a UE indication identifying the UE. The IMS node stores a registration of the UE in the IMS node, in addition to a previously stored registration of the UE, with the proviso that the indicated network slice identity differs from a previous network slice identity of the previously stored registration of the UE and thereby allowing parallel active communications using the registration and the previously stored registration.
