Accordingly, embodiments herein disclose a method for handling a closed access group (CAG) related procedure in a wireless communication system. A network may receive a radio resource control (RRC) resume request message from a user equipment (UE). The network may determine whether the at least one CAG identifier (ID) broadcasted in a CAG cell is included in an allowed CAG list of the UE (100) in response to the RRC resume request message. The network may proceed with a RRC resume procedure in response to determining that the at least one CAG ID is included in the allowed CAG list.

Methods and systems related to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE) are provided. An operation method of a terminal in a wireless communication system is provided, the method including checking information on at least one control resource set carrying scheduling information for scheduling remaining system information based on a master information block (MIB) received from a base station, checking the scheduling information in the at least one control resource set, and receiving the remaining system information based on the scheduling information.

A customer premises node device can receive an authentication message from a fixed cellular communication device that operates according to a third-generation mobile network access standard (e.g., a 3G alarm panel). The customer premises node device can facilitate transmitting the authentication message, to a network node that operates according to a fourth-generation mobile network access standard. The authentication message can then be routed via mobile network components, including a network gateway device, to a home location registry device, which can authenticate the 3G fixed cellular communication device for communications on a 4G mobile network.

The present invention provides a mobile communication system sub-network comprising a macrocell base station, and a plurality of small cell base stations, the plurality of small cell base stations being in wireless communication with the macrocell base station, wherein each small cell base station is either in direct connection with the macrocell base station or is in connection with the macrocell base station via one or more other small cell base stations, wherein the macrocell base station is arranged to configure a UE device having a RRC connection to the macrocell base station with candidate small cell base station information for enabling the UE device to switch autonomously between small cell base stations, and wherein the macrocell base station is arranged to configure the small cell base stations with small cell base station configuration information.

Embodiments include methods, for a first centralized unit (CU) in a radio access network (RAN), to configure a user equipment (UE) to communicate via first and second distributed units (DUs). Such methods include initiating a first radio resource control (RRC) entity to communicate with the UE via a first RRC connection through the first DU, and selecting the second DU to communicate with the UE in a dual-connectivity (DC) configuration with the first DU. Such methods include performing one or more of the following based on determining the second DU is associated with the first CU: initiating a second RRC entity within the first CU to communicate with the UE via a second RRC connection through the second DU; and establishing one or more further radio bearers with the UE via the second DU. Other embodiments include methods for a UE, and CUs and UEs configured to perform such methods.

In a communication system, an eNB and a UE transmit and receive a UE monitoring message for confirming the state of the UE in a predetermined UE monitoring period. For example, in UE monitoring periods, a UE monitoring procedure is performed, so that the UE transmits the UE monitoring message to the eNB. Upon receipt of the UE monitoring message, the eNB transmits delivery confirmation information to the UE. The UE monitoring period is set as, for example, a period shorter than a TAU period. This allows the UE monitoring process to confirm the state of the UE even if the TAU period is lengthened. The eNB may transmit the UE monitoring message to the UE.

In one example, a user equipment (UE) has a non-Third Generation Partnership Project (non-3GPP) radio transceiver for communication in a local private non-3GPP wireless network and a 3GPP radio transceiver for communication in a 3GPP network, where the 3GPP network may be a public 3GPP network or a local private 3GPP network operative in a shared spectrum according to a system for shared spectrum access. Initially, the UE may operate the 3GPP radio transceiver for communication in the public 3GPP network, without performing regular scanning for the local private 3GPP network. In a scan operation using the non-3GPP radio transceiver, the UE may receive from a non-3GPP access point of the local private non-3GPP wireless network one or more messages including one or more information elements. If an information element indicates presence of the local private 3GPP network, the UE may identify and register with the local private 3GPP network.

This application provides a communication method and apparatus. The method includes: a terminal sending first network information of a second network to a first network, where the first network information includes first indication information of the second network, and the first indication information indicating that the terminal requests to access the second network. The terminal performs onboarding delivery authentication of the second network through the first network. After onboarding delivery authentication of the second network succeeds, the terminal receives configuration information of the first network through the first network, and obtains a credential of the second network through the first network from an online sign-up server in the second network.

An apparatus, method and compute program is described comprising receiving (at a network node) one or more network node configuration messages from a control module, wherein each network node configuration message relates to network measurement of one or more restricted access resources for one or more groups of users of a public land mobile network, wherein the one or more restricted access resources are indicated within the network node configuration messages with one or more resource indicators; and sending one or more user device configuration messages to one or more selected user devices respectively, each user device configuration message including one or more resource indicators and one or more parameters, wherein the one or more resource indicators identify the one or more restricted access resources.
