The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and security-related service, etc.) on the basis of 5G communication technology and IoT-related technology. The present disclosure discloses a method and a device for controlling the RRC state mismatch issue of a terminal, and also discloses a method and a device for providing access control configuration information of a terminal.

A control device includes: a receiving unit that receives a first beacon request for performing registration processing from a communication terminal device; a detection unit that detects a control signal indicating a request for starting the registration processing; a registration control unit that starts the registration processing when the detection unit detects the control signal and executes the registration processing for a certain period; and a transmission control unit that: transmits the beacon signal when the receiving unit receives the first beacon request in a period during which the registration control unit is executing the registration processing; and avoids transmitting the beacon signal when the first beacon request is received in a period during which the registration control unit is not executing the registration processing.

Systems and methods for small cell idle mode mobility include receiving, at a first small cell of a preconfigured cluster of small cells, a mobility area update request from a user equipment (UE). The method can also include registering location information of the UE with a small cell gateway, and retrieving a core network periodic timer for the UE from a mobility server. If certain conditions are met, the first small cell forwards the mobility area update request to a core network via the small cell gateway. Otherwise, the method can include the first small cell updating the location information of the UE with the mobility server, generating a locally-generated mobility area update accept message, and sending a locally generated mobility area update accept message to the UE along with a local periodic timer instructing the UE to send another mobility area update request when the local periodic timer expires.

Systems and methods for small cell idle mode mobility include receiving, at a first small cell of a preconfigured cluster of small cells, a mobility area update request from a user equipment (UE). The method can also include registering location information of the UE with a small cell gateway, and retrieving a core network periodic timer for the UE from a mobility server. If certain conditions are met, the first small cell forwards the mobility area update request to a core network via the small cell gateway.

A method for controlling access to wireless communications includes generating an overlay to a portion of an existing wireless network by controlling radio frequency (RF) equipment to establish a defined geographical volume as the overlay; receiving an indication of wireless devices within the volume, the indication including three-dimensional positions of the wireless devices within the boundary; establishing identities for the wireless devices, the identities selected from the group consisting of allowed, unknown, and restricted; generating a private network encompassing at least a portion of the volume; locking and maintaining locked unknown and restricted wireless devices to the processor; and directing allowed wireless devices to access the private network for wireless communications within the volume.

A Session Initiation Protocol (SIP)-based network includes at least two SIP user agents, wherein each SIP user agent is configured to act as a user agent client (UAC) for requesting a service function and as a user agent server (UAS) for responding to a request service function. The UAC is configured to initiate a registration with the UAS, wherein the registration comprises a field for indicating infinity registration capability and a field for indicating management communication capability. The UAS is configured to send to the UAC, a registration expiry timer with a value equal to infinity and a management header including a onetime unique token.
