Abstract
The present invention relates to a mobile radio communications network device operative to transmit a non-access stratum (NAS) signal to a mobile radio communications device after a failed attempt by said mobile radio communications device to access a mobile radio communications network via said network device, said network device being arranged to include within said NAS signal information indicating to said mobile radio communications device which one of: (i) an existing NAS signalling connection; or (ii) a new NAS signalling connection, said radio mobile communications device should employ to attempt re-establishment of connection with said network device. The present invention also relates to a NAS signal to be employed by such a network device, a mobile radio communications device for exchanging signalling with the network device and related methods of such devices.
