The present invention relates to a method for routing area (RA) update request messages which in accordance with a time period broadcasted from the network are periodically sent from an MS (Mobile Station) to an SGSN (Serving GPRS Support Node) through a BSS (Base Station System), which SGSN supports GPRS (General Packet Radio Service), and which as a result of a routing area update procedure will return an appropriate accept message, and for the purpose of taking into account the differentiation in nature of normal routing area update procedure and periodic updates, it is according to the present invention suggested that for the purpose of simplifying said routing area update procedure, there is broadcasted a new indicator from the network together with the time periode for the periodic routing updates, said indicator being adapted to determine whether the periodic routing update procedure is performed ciphered instead of unciphered.
Method for routing area (RA) update request messages which in accordance with a time period broadcasted from a network are periodically sent from an MS (Mobile Station) to a Service node, and which as a result of a routing area update procedure will return an appropriate accept message, the method comprising:
