    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. A method of handling control plane data in a wireless network. The method comprises sending, by a user entity (UE), a non-access stratum (NAS) message along with an indication data to a mobility management (MM) core network entity. The MM core network entity processes the received NAS message and the indication data. The MM core network entity determines status of network congestion upon processing the processed NAS message. Sending, by the MM core network entity, a response to the UE based on at least one of the processed indication data and the determined network congestion.

    Abstract: Accordingly, embodiments herein provide a system for managing anti-steering of roaming in a wireless communication network. The system includes a HPLMN, a VPLMN and a UE. The HPLMN obtains a register request message from the VPLMN and derives at least one HPLMN specific security key based on at least one security parameter. Further, the HPLMN protects a preferred PLMN list using the at least one HPLMN specific security key and the security parameter and sends the protected preferred PLMN list to the VPLMN along with necessary security information. Further, the VPLMN is configured to receive the protected preferred PLMN list from the HPLMN and send a message including the protected preferred PLMN list to the UE. The message mandates the VPLMN to send the preferred PLMN list transparently to the UE. Further, the UE is configured to receive the message including the preferred PLMN list from the VPLMN.

    Abstract: A method of a terminal and the terminal are provided. The method includes detecting a location area change when a congestion timer is running and one of a general packet radio service (GPRS) update status indicating “GU1 UPDATED,” a mobility management (MM) update status indicating “U1 UPDATED,” and an evolved packet system “EPS” update status indicating “EU1 UPDATED” is indicated; adaptively changing the GPRS update status to “GU2 NOT UPDATED,” the MM update status to “U2 NOT UPDATED,” and the EPS update status to “EU2 NOT UPDATED”; and entering a state of “GMM-REGISTERED.ATTEMPTING-TO-UPDATE,” “MM IDLE, ATTEMPTING TO UPDATE,” or “EMM-REGISTERED.ATTEMPTING-TO-UPDATE,” in accordance with one of “GU2 NOT UPDATED,” “U2 NOT UPDATED,” and “EU2 NOT UPDATED.”
