20100081455 | TRACKING AREA SIGNALLING IN CELLULAR MOBILE RADIO COMMUNICATIONS NETWORKS - The present invention provides for a method of controlling tracking area signaling within a cellular mobile radio communications network and comprising the steps of, determining if the mobile radio communications devices is stationary, providing an indication to the network that the mobile radio communications device is stationary, and in the network, assigning at least one tracking area and/or an equivalent tracking area list to the mobile radio communications device responsive to the indication that the mobile radio communications device is stationary. | 04-01-2010 |
20100091704 | Mobile telecommunications and random access preamble content - The present invention provides for a mobile radio communications device of a mobile radio communications network arranged for delivering a non-synchronized random access preamble message such that the non-synchronized random access preamble message comprises a multi-bit message including Cause ID bits and selective bits comprising at least signature bits for collision avoidance, and in which the inclusion of CQI bits is determined responsive to signaling received from the network and indicative of cell characteristics or parameters. | 04-15-2010 |
20100261474 | PLMN SELECTION IN MULTI-NETWORK ENVIRONMENT - 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. | 10-14-2010 |

20100067375 | LOAD SHARING IN MOBILE RADIO COMMUNCATIONS NETWORK - The present invention relates to a method of providing load sharing through network controlled cell reselection in a mobile radio communications network, including delivering an offset parameter to User Equipment within the network for biasing the said reselection, the method further including the step of broadcasting the offset parameter to the User Equipment within system information and so as to be cell-specific, further delivering load-sharing-priority-keys and subsequently processing the offset parameter with the load-sharing-priority-keys so as to become User Equipment specific. | 03-18-2010 |
20120264428 | NETWORK SELECTION - The present invention provides for method of selection by a User Device of a desired PLMN offering a desired service, such as emergency bearer services, from a list of PLMNs within a shared network environment, the method includes creating a list of network identifiers for the said plurality of PLMNs respectively, and locating the identifier of the said desired PLMN at a predetermined position within the said list. Related User Devices and network node devices are also provided. | 10-18-2012 |
20130324123 | COMMUNICATION SYSTEM - 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. | 12-05-2013 |
20150045027 | DEVICE AND METHOD FOR AUTONOMOUSLY PERFORMING AN IMPLICIT DETACH OPERATION - A device can communicate wirelessly with another device in a wireless communication system and is arranged to receive configuring information defining a detach configuration. By using the detach configuration, the device can autonomously perform an implicit detach operation thus terminating a communication link between the device and the other device. Optionally, when the detach configuration includes an explicit detach mode, the device transmits an indicating signal indicating the detach operation. The indicating signal transmitted by the device may comprise a DETACH REQUEST message. Preferably the device can store the configuring information and can store program information, and can perform the detach operation by using the stored program information and the stored configuring information. | 02-12-2015 |
20150085824 | WIRELESS TERMINAL AND METHOD OF OPERATING - A wireless terminal can communicate with a first network of first type and a second network of second different type. The wireless terminal performs a packet-domain attachment to the first network and initiates a ready timer indicating that the wireless terminal is in an attached state and has recently sent data to the first network. The wireless terminal initiates an inter-system change from the first network to the second network whereby the wireless terminal becomes registered to the second network. Advantageously the wireless terminal has means for rendering the ready timer ineffective when the inter-system change is performed. The network apparatus has means for initiating its own ready timer dependent on the attachment occurring, this ready timer also indicating that the wireless terminal is in an attached state and has recently sent data to the first network. | 03-26-2015 |
20150087354 | INTERSYSTEM CHANGE BETWEEN DIFFERENT RADIO ACCESS NETWORKS - A wireless terminal can communicate with two radio access networks (RAN) ( | 03-26-2015 |
