摘要： Apparatuses and methods for IMS support for standalone non-public networks (SNPNs) are disclosed. In one embodiment, a method implemented in a policy node includes sending a Public Land Mobile Network, PLMN, identifier, ID, and a network identifier, NID, a combination of the PLMN ID and the NID identifying a standalone non-public network, SNPN being associated with a user equipment, UE. In one embodiment, a method implemented in an application function, AF, node includes receiving an Internet Protocol, IP, Multimedia Subsystem, IMS, registration request from a user equipment, UE; and as a result of receiving the IMS registration request, subscribing to be notified of a Public Land Mobile Network, PLMN, identifier, ID, and a network identifier, NID, a combination of the PLMN ID and the NID identifying a standalone non-public network, SNPN, associated with the UE.

摘要： This disclosure describes a user equipment device (UE). The UE includes one or more antennas; one or more radios, where each of the radios is configured to perform cellular communication using a plurality of radio access technologies (RATs) that support voice over an Internet protocol (IP) multimedia subsystem (IMS); one or more processors coupled to the one or more radios, where the one or more processors are configured to cause the UE to perform operations including: sending, via a first RAT, a first request for IMS registration to an IMS server; receiving, from the IMS server, an IMS rejection message indicating failure of the IMS registration; determining, based on the IMS rejection message, that the IMS registration failure is temporary; responsively re-attempting IMS registration with the IMS server; and determining to camp on the first RAT in response to receiving an IMS acceptance message from the IMS server.

摘要： In a LTE network user devices can access voice application service via Voice over LTE (VoLTE) and Voice over WiFi (VoWiFi). To detect faults in the data link associated with an evolved packet data gateway for providing access by the user device to the LTE network from a non-trusted network which will affect VoWiFi capability, a packet data gateway monitors the status of ePDG and if a fault is detected, the user device is notified that it should connect to voice services via VoLTE.

摘要： Apparatuses, methods, and systems are disclosed for determining mobile network policy freshness. One method includes accessing a first policy associated with a first mobile network, a first policy identifier, and a freshness parameter. The method includes determining, based on the freshness parameter, whether the first policy is fresh. The method includes transmitting a registration message to a second mobile network. The registration message includes the first policy identifier in response to determining that the first policy is not fresh.

摘要： A network data collection method from application function device for network data analytic function is disclosed. The network data collection method includes transmitting a Naf_EventExposure_Subscribe message for a subscription of an event into an application function (AF) device; and receiving a Naf_EventExposure_Notify message from the AF device when the NWDAF subscribes the event.

摘要： A wireless headset includes a first wireless transceiver module, an account processing module, a session control module, a headset module, and a network communication processing module. The first wireless transceiver module is configured to implement data transmission between the wireless headset and a wireless base station via a first wireless communication protocol. The network communication processing module is configured to process a registration instruction sent by the account processing module to obtain a registration request, and send the registration request to the first wireless transceiver module. The first wireless transceiver module sends the registration request to the wireless base station. The network communication processing module is further configured to forward session control data sent by the session control module and media data of the headset module to the first wireless transceiver module.

摘要： A communication interface and a device control, management and monitoring system are provided to enable the networking of and communication between multiple devices operating under different protocols. The communication interface may act as a translator or protocol converter that reformats transmissions from one protocol to another based on protocol compatibility between the recipient and transmitting devices. The device control and monitoring system may store predefined rules that are triggered when specified conditions associated with the networked devices are detected. The rules may specify an action to take such as transmitting a discount offer to a user or turning off a light. According to one or more arrangements, the communication interface may act as an intermediary between the networked devices and the device control system so that the device control system is not required to understand or be compatible with the various other protocols used by the networked devices.

摘要： Embodiments provide a service request processing method, a related device, and a communications system in an IMS network. In some embodiments, because 5GC network slices correspond to different services, P-CSCFs in the IMS also correspond to different service information. After receiving a terminated service request sent by an I-CSCF, a first S-CSCF can obtain an address of a corresponding P-CSCF based on terminated service information carried in the terminated service request. Then, the first S-CSCF sends the terminated service request to the P-CSCF corresponding to the address, and the P-CSCF processes the terminated service request.
