The invention relates to managing and controlling access by a user wireless device (MD) to a wireless local area network (WLAN) at an access point or "hotspot", while protecting the security of the WLAN. The hotspot and associated advertisement describe an available communication service at the hotspot. A RFID device is embedded in the advertisement providing instructions for attachment of the user's mobile device (MD) to the communication service, e.g. a WLAN. After evaluation of the instructions and establishing a security relation between the MD and a mobile management entity (MME) included in a wide area network (WAN), the MME provides attachment information for the MD to the WLAN. The attachment is completed after verification by the WLAN of the MME approval of the MD attachment, and establishing a session key for messages between the MD and the WLAN.
