There is provided a method of initiating a network attachment procedure by a mobile device, the mobile device being attached to a network other than the home network of the mobile device, and wherein location information for the mobile device in said other network is stored in a visitor location register, VLR, in said other network, the method comprising sending a signal from the home network to said other network to cause the location information for the mobile device to be deleted from the VLR in said other network; the mobile device sending a request for a service or session to said other network after the location information has been deleted from the VLR; and on rejection of that request by said other network, initiating a network attachment procedure in which the mobile device reattaches to a network. Suitable for when a mobile device is roaming in a foreign network close to the border with the home network where coverage may overlap. May also be used to prevent accidental roaming. |
