    摘要: 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. nThe IMS node obtains (303) 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 (304) from the first device, a call invitation to the second device, the IMS node enforces (306) 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.

    摘要: A first network function in a network node is described. The network node comprises a communication interface and processing circuitry. The communication interface is configured to transmit a registration to a registry function to register an associated service profile indicating a network node capability to expose at least one of Internet Protocol, IP, Multimedia Subsystem, IMS, events and IMS analytics data on behalf of one or more IMS nodes; receive a request to subscribe to and be notified of the at least one of the IMS events and the IMS analytics data; notify of the at least one of the IMS events and the IMS analytics data based at least in part on the received request. Information related to the at least one of the IMS events and the IMS analytics data is obtained, by the processing circuitry, from the corresponding IMS nodes in the IMS network.

    摘要: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station, first system information including information on at least one stand-alone non-public network (SNPN), receiving, from the base station, second system information including information on a first list of at least one group identifier for network selection (GIN) to support an access using credentials from a credentials holder or to enable a UE onboarding and information on a second list of associations between the at least one GIN and the at least one SNPN in the first system information, selecting an SNPN based on the first system information and the second system information; and performing, with the base station, a radio resource control (RRC) establishment for the selected SNPN.

    摘要: Embodiments herein provide a method for performing voice call performance by a user equipment (UE). A voice call is preferred for a cellular network over a Wi-Fi network, an IMS is registered over a 5G BS, the 5G BS is not supported for the voice call, and a Wi-Fi device and a 4G BS are supported for the voice call. The method includes: detecting an event related to the voice call; comparing signal strength of the Wi-Fi device and signal strength of the 4G BS; shifting an IMS registration from the 5G BS to the Wi-Fi device, upon determining that the signal strength of the Wi-Fi device is greater than the signal strength of the 4G BS; and initiating the voice call over the Wi-Fi device upon detecting a trigger for the voice call.

    摘要: Providing a voice call includes: receiving, from a user equipment (UE), a request to initiate a voice call traffic session; requesting setup of a voice call data pipe; based on at least a setup of the voice call data pipe not completing prior to a timer event, transmitting voice packets over a signaling data pipe; and based on at least the voice call data pipe setup completing, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe. Placing a voice call includes: requesting, by the UE, to initiate the voice call traffic session; based on at least a first trigger event, transmitting voice packets over the signaling data pipe; and based on at least a second trigger event, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe.

    摘要: Systems and methods are provided which enable the identification and resolution of connectivity issues between a user equipment (UE) and an Internet Protocol (IP) Multimedia System (IMS) that results in missed incoming voice calls. The identification of missed calls may be based on the receipt of other notifications that can tangentially or relatedly indicate a missed voice call, e.g., voicemail notifications. In the event such a notification is received without having received the call itself, a determination can be made that a connectivity issue(s) exists, and corrective action(s) may be automatically taken to re-establish IMS registration and synchronization by/with the UE.

    摘要: Systems and methods for simultaneous calling in a cellular communications system are disclosed. In one embodiment, a method performed by a first wireless communication device for simultaneous Internet Protocol (IP) Multimedia Subsystem (IMS) sessions between the first wireless communication device and two or more other wireless communication devices comprises establishing a first IMS session with a second wireless communication device and, while the first IMS session is ongoing and without placing the first IMS session on hold, establishing a second IMS session with a third wireless communication device. In this manner, simultaneous calling is enabled, which will, for example, allow machines to multitask in comparison to existing non-simultaneous calling.
