Abstract: A method of and a device for operating a service discovery and selection function in a telecommunications system, wherein the service discovery and selection function registers a service profile of a service provided by at least one service producer of the telecommunications system. The service profile among others includes consistency group information and proximity information. The consistency group information identifies instances of the service sharing a same state and the proximity information identifies deployment of the instances in the telecommunications system. The service discovery and selection function, from the service profile, based on service selection criteria, selects a single service instance of the service for a service consumer of the telecommunications system requesting the service, and identifies the selected service instance to the service consumer.

Abstract: A method for managing storage resources in a network system is described. The method includes registering, by a storage resource controller, with a network repository function; receiving, by the storage resource controller, an operation request from a consumer service; selecting, by the storage resource controller, a resource management instance from a plurality of resource management instances managed by the storage resource controller for assignment to the consumer service; forwarding, by the storage resource controller, the operation request to the selected resource management instance; receiving, by the storage resource controller, an operation response from the selected resource management instance; and forwarding, by the storage resource controller, the operation response to the consumer service.

Abstract: Methods are disclosed for provisioning and/or controlling operator profiles in terminals, each having an integrated circuit card identified by an integrated circuit card identifier. According to one aspect, a discovery server is configured with an authorization table including associations of integrated circuit card identifier, service provider identifier, and operator identifier(s). The discovery server receives, from a data preparation node, an event registration request that includes a number of elements. The discovery server determines whether the event is authorized. If so, the event is registered. This enables a terminal to seek to retrieve the event, to contact the data preparation node, and to eventually perform the profile operation. Some embodiments enable the network-initiated provisioning and/or controlling of operator profiles in machine-to-machine devices.

Abstract: The present invention faces the issue of improving isolation of network slices in network slicing deployments where a centralized User Data Management, which includes subscription information for all users in a network with a plurality of network slices, is shared by the plurality of network slices. To solve this issue, the present invention provides for a distributed slice data repository for handling slice selection data for users equipped with a user equipment, UE, in a network that includes a plurality of network slices. This distributed slice data repository has: a slice user data repository, SDR, per network slice basis and including subscription information for each UE to be served by the network slice, and a slice selection repository, SSR, which is external to any network slice, shared by the plurality of network slices, and only includes slice selection data for every UE in the network.

Abstract: A technique for operating an RSP node (100), which is configured for remote subscriber identity module, SIM, provisioning, RSP, and comprises or is connectable to an interface (502) for communication with an MNO node (200) of a mobile network operator, MNO, is described. As to a method aspect of the technique, a download order message from the MNO node (200) is received through the interface (502). The download order message includes data (604) for generating a SIM profile (602). The SIM profile (602) is generated in response to the download order message according to the data (604) received for generating the SIM profile (602). A result (606) of the SIM profile generation is sent through the interface (502) to the MNO node (200).

Abstract: A subscriber server routes a terminating call in a network that includes a circuit switched (CS) network, a packet switched (PS) network, and an IP Multimedia Subsystem (IMS). The server receives a request for routing information in relation to the terminating call from a CS node in the CS network. A determination is made at server based on whether a UE associated with the terminating call is registered in the IMS and the UE has access to the PS network. The server instructs the CS node to route the terminating call in the CS network when the UE is not registered in the IMS or when the UE does not have access to the PS network. The server instructs the CS node to send the terminating call to the IMS for handling when the UE is registered in the IMS and when the UE has access to the PS network.

Abstract: Data management at a directory database having a data entry in a directory includes associating the data entry with first status information representing a first current storage status of the data entry at the directory database. The directory database receives, from a client, a request for modifying the data entry, and in association with the request, second status information representing a second current storage status of the data entry at the directory database. The second current storage status indicates a latest available current storage status of the data entry as available to the client. The directory database will modify the data entry according to the request if the first status information and the second status information are determined to match with respect to the first and second current storage statuses of the data entry at the directory database.

The server receives a request for routing information in relation to the terminating call from a CS node in the CS network. A determination is made at server based on whether a UE associated with the terminating call is registered in the IMS and the UE has access to the PS network. The server instructs the CS node to route the terminating call in the CS network when the UE is not registered in the IMS or when the UE does not have access to the PS network. The server instructs the CS node to send the terminating call to the IMS for handling when the UE is registered in the IMS and when the UE has access to the PS network.
