Due to possibly different standard versions implemented in a mobile station (MS) and a network, the MS may not be able to interpret all reject-cause values used by the network. In this case, a MS may receive upon a mobility-management (MM) request a reject message with an unknown reject-cause value and re-transmit its MM request. According to one aspect of the invention, a MM method for a mobile station in a public land mobile network, hereinafter network, is provided. The method comprises the steps of ascertaining on the network side whether the request is to be rejected, if the mobility-management request is to be rejected, ascertaining on the network side a suitable first reject-cause information element indicating the reason for rejection, and ascertaining whether the first reject-cause value is known to the mobile station, if the reject-cause value is not known to the mobile station, sending to the mobile station a mobility-management response suitable to prevent a re-transmission of the mobility-management request by the mobile station.
A mobility-management method related to a mobile station in a public land mobile network, comprising the steps of:
A mobility-management unit for a network node of a public land mobile network, the mobility-management unit being configured to process mobility-management requests received from a mobile station, and comprising a rejection-management unit, which is configured to
A software module for implementation of a mobility-management unit in a network node of a public land mobile network, comprising a rejection-management sub-module, which is configured to
