摘要: A method performed by a first network node (12) for handling a communication session, wherein the first network node (12) is associated with a first communication network operated by a first operator. The first network node sets Sup a data channel between the first network node and a second wireless device (14). The second wireless device is associated with a second communication network operated by a second operator. The first network node further provides data over the setup data channel to the second wireless device (14), wherein the data is related to a service provided for a first wireless device serviced by the first operator.

摘要: A method performed by a first IP multimedia system, IMS, node (15), for handling a network function in a communication network. The first IMS node (15) requests a first core network node (13) for at least a part of contact information of a network function instance, and receives a response from the first core network node (13) with at least the part of the contact information for the network function instance. The first IMS node (15) communicates with a second IMS node (16) or a core network node over a service based interface, based on the received part of the contact information for the network function instance.

摘要: A communication network allows an end user to dynamically select a user device among user devices associated with the user's subscription as the primary user device by defining a primary capability tag or attribute. Selection of a user device sets the primary capability tag of the selected user device, which is published towards an application server. The application server notifies all other user devices in the group of devices. If a previous user device in the group of user devices was set as the primary user device, then, in response to the notification, the previous user device performs a re-registration with the network removing the previous user device as the primary user device for the services associated with the user subscription. The selected user device also performs a re-registration/registration with the network so all incoming requests for services associated with the user subscription are sent to the selected user device.
