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.
