    Abstract: A measurement method of a non-connected state user-side device, a measurement method of a non-connected state user-side device and a user-side device are provided. The method includes: acquiring, by the user-side device, non-connected state measurement configuration information; performing, by the user-side device, a non-connected state measurement according to the non-connected state measurement configuration information. According to the present disclosure, based on the non-connected state measurement configuration information, the user-side device may help the network-side device to select a suitable user-side device to perform the non-connected state measurement, thereby achieving the measurement of the non-connected state user-side device. In addition, the non-connected state measurement configuration information may include inter-frequency measurement configuration information, thereby achieving an inter-frequency measurement and saving resources of the user-side device during the measurement.

    Abstract: A subscriber identity module (SIM). The SIM comprises a processor, a non-transitory memory storing a configuration file, a wireless identity, a wireless access key, and a remote update agent stored in the non-transitory memory. When executed by the processor, the remote update agent determines that the SIM is communicatively coupled to a wireless communication network via a radio transceiver of a communication device with which the SIM is associated, in response to determining that the SIM is communicatively coupled to the wireless communication network, sends a provide local information (PLI) command to the mobile communication device to acquire network measurement results (NMR) based on the configuration file, transmits NMR data via the radio transceiver using a bearer independent protocol (BIP), receives SIM update information via the radio transceiver, and stores the SIM update information in the configuration file in the non-transitory memory.

    Abstract: A communication technique that combines a 5G communication system for supporting a data rate that is higher than that of a beyond 4G system with IoT technology, and a system thereof are provided. The technique may be applied to intelligent services on the basis of 5G communication technology and IoT related technology, such as smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, etc. A method of performing access deregistration by a user equipment (UE) and an apparatus therefor are provided. The method includes, when the UE is registered on both 3rd generation partnership project (3GPP) access and non-3GPP access, transmitting, to an access and mobility management function (AMF), a deregistration request message to deregister the non-3GPP access over the 3GPP access, and receiving, from the AMF, a deregistration accept message corresponding to the deregistration request message over the 3GPP access.
