Abstract

A system is described in which a default MME (9A) receives a NAS message (S501, S505) from a mobile device (3D); sends a rerouting request (S509) to a base station (5) serving the mobile device (3D) and includes information identifying a group of dedicated MMEs (9D) to which the NAS message should be rerouted. If none of the dedicated MMEs (9D) is available, then the default MME (9A) receives a message from the base station (5), the message rerouting the NAS message to the default MME (9A), instead of a dedicated MME (9D). The default MME (9A) either proceeds (S515a) to serving the mobile device (3D) or the default MME (9A) rejects (S515b) the NAS message.
