20120117619 | SECURE NETWORK CONNECTION ALLOWING CHOICE OF A SUITABLE SECURITY ALGORITHM - The invention provides for a method for use in a mobile radio communications device network connection procedure and including the step of, at a network, sending to a mobile radio communications device a list of a plurality of security algorithms supported in the network and so as to allow choice of a suitable algorithm irrespective of the degree of update that the device may have experienced. | 05-10-2012 |
20120117623 | SECURE NETWORK CONNECTION - The invention provides for a method for use in a mobile radio communications network connection procedure and including the step of rejecting at a mobile radio communications device a handover request from a network responsive to determination of support of the security algorithm associated with the handover, and for a mobile radio communications device arranged to determine support of security algorithms as proposed by the network, preferably at AS level, within a handover command, and to provide notification to the network of rejection of the connection due to non-support of the algorithm. | 05-10-2012 |
20120129491 | METHOD OF PROVIDING TELECOMMUNICATIONS NETWORK SECURITY - Disclosed is a method of providing network security within a mobile radio communications network and including creating a security context for communications between a mobile radio communications device and the network, the security context being created responsive to an input parameter such as the downlink NAS count, and the method further including, as part of each initial handover attempt, controlling the parameter so as to apply a version of the parameter different from a previous version, for example as incremented downlink NAS count, and preferably independently of network signaling messages. | 05-24-2012 |
20130035056 | COMMUNICATIONS SYSTEM - A cellular communications system is provided in which a user device maintains and provides a last non-emergency security context to a core network when moving from a network that provided restricted services to a network that provides unrestricted services. In this way, re-authentication of the user device can be avoided in the network that provided unrestricted services. | 02-07-2013 |
20130148565 | MOBILE RADIO COMMUNICATIONS DEVICE FOR CLOSED SUBSCRIBER GROUP MANAGEMENT - The present invention provides for a mobile radio communications device, and related method of operation, arranged for closed subscriber group selection and for the storage of closed subscriber group information in the device, the stored information including information configured as a whitelist of closed subscriber group identities delivered between non-access-stratum layer and access-stratum layer within the device, and the device being further arranged to remove a previous user-selected closed subscriber group identity from the whitelist responsive to the device connecting to a cell is different from that identified by the previous user-selected closed subscriber group identity, and which different cell can comprise for example a non-CSG cell. | 06-13-2013 |
20130281063 | NETWORK ENTITY, COMMUNICATION DEVICE, MOBILE COMMUNICATION DEVICE AND METHOD THEREOF - A communication system is described in which a mobile communication device receives MDT configuration requests from a base station or radio network controller to initiate an MDT measurement session for obtaining measurement data and location related data for identifying a location to which said measurement data relates. The mobile communication device checks a user consent indicator in memory and only provides the location related data if the user consent indicator indicates that a user of the mobile communication device consents to the provision the location related data. | 10-24-2013 |
20130312063 | SECURE NETWORK CONNECTION - The invention provides for a method for use in a mobile radio communications network connection procedure and including the step of rejecting at a mobile radio communications device a handover request from a network responsive to determination of support of the security algorithm associated with the handover, and for a mobile radio communications device arranged to determine support of security algorithms as proposed by the network, preferably at AS level, within a handover command, and to provide notification to the network of rejection of the connection due to non-support of the algorithm. | 11-21-2013 |
20150052580 | COMMUNICATIONS SYSTEM - A communications system is provided. A network device ( | 02-19-2015 |
20150063145 | RADIO MEASUREMENT REPORTING - The present invention provides for a mobile radio communications device arranged to operate according to a first radio access technology for communication in a mobile radio communications network, and according to a second radio access technology, and to related network device and methods of operation, whereby radio measurements taken by the mobile radio communications device in relation to the first radio access technology can be polluted by coexistence interference from the second radio access technology, the mobile radio communications device being arranged to indicate to the network its capability of providing enhanced radio measurements taken while experiencing pollution by coexistence interference prior to any such provision and, if to be provided, to include interference information. | 03-05-2015 |
