摘要:
A communication system for supporting machine type communication within a cellular communication network is described in which a communication device is allocated a permanent offline area in which the communication device is expected to be located whilst not attached for communication within the network. The communication device identifies a cell in which the communication device is currently located and determines whether or not the cell forms part of the permanent offline area or a temporary offline area that comprises a previously visited cell that is not part of the permanent offline area. If these areas do not comprise the cell in which the communication device is currently located, the communication device attaches to the network and communicates information identifying the cell in which the communication device is currently located to the network.

The present invention provides for a mobile radio communications device operative to signal a non-access stratum message to a mobile radio communications network device, for establishing and/or maintaining network connection, the device being arranged to include within the message a flag indicating the availability of extended NAS messaging found within an additional message separate from, but forming an extension to the non-access stratum message, and also for a signaling structure to be employed by such a device and a network device for exchanging signaling therewith and of course to related methods of such devices.

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.

The present invention provides a method of PLMN selection subsequent to a change in cell for a mobile radio communications device in a multi-network cellular environment, the method including the steps of monitoring system information within a mobile radio communications device to determine the availability of a HPLMN or any other higher priority PLMN than current registered PLMN, and selecting the said HPLMN or higher priority PLMN than current registered PLMN if identified as available, and also a related network-sharing-capable UE that, when registered with a visitor PLMN, can readily check the availability of its HPLMN or any other higher priority PLMN in the system information whenever it moves to a new location area and, assuming the HPLMN or higher priority PLMN to be found, can then reselect to that PLMN.

The invention provides a method of controlling LA-based update procedure in a mobile radio communications network, and including the step of determining the reason for the LA-based update request, and varying connection procedures upon receipt of such request and responsive to the determination, and so can also provide a mobile radio communications network device arranged for operation in the network including plural terminal devices, the network device being arranged to forward to a target network device an indication of reasoning for a LA-based update procedure (during CSFB to the legacy system for example). Further the invention can also be embodied in a mobile radio communications network target device arranged for operation in the network including plural terminal devices and further arranged to monitor for an indication from a network device for reasoning for a LA-based update procedure, and further arranged to vary a connection procedure responsive to the said monitoring.

摘要:
The invention concerns a method for optimizing a UE PDN (Packet Data Network) connection when said UE enters a VPLMN (Visited PLMN) characterized by automatically allocating a default bearer to said UE in said VPLMN during Tracking Area Update procedure. The method according to the invention is preferably but not exclusively used for allowing a local breakout of user plane or control plane traffic when the UE is roaming between several PLMNs.
