摘要： The present invention relates to a method for a secondary station to obtain a time reference in a cellular network in order to verify the freshness of received messages. The method comprises the steps of receiving a plurality of system information, SI, messages from a plurality of primary stations, said SI messages including each a respective time reference information related to the corresponding primary station, checking the validity of a received signature for each of the primary stations, checking a cell identifier for each of the primary stations with a valid signature, and ignoring time reference information from primary stations with a cell identifier being identical to another primary station and having an earlier value than the one from the other primary station, and deducing a local time reference from one or more of the time reference information originating from primary stations with a valid signature.

摘要： Apparatuses, methods, and systems are disclosed for supporting authentication with a mobile core network using a concealed identity. One apparatus (300) includes a processor (305) that sends (505) a first authentication message that includes a concealed identifier to a network function to authenticate with a mobile communication network via a non-3GPP access network. The processor (305) receives (510) a second authentication message from the network function in response to the first authentication message. The second authentication message comprises an authentication response based on the concealed identifier. The processor (305) completes (515) authentication with the mobile communication network in response to the authentication response comprising a challenge packet. The processor (305) receives (520) configuration information for accessing the mobile communication network in response to successful authentication with the mobile communication network.

摘要： A method performed by a UE (10) for evaluating validity of a radio link, wherein the UE (10) is operating in a wireless communication network, and wherein the UE (10) receives a signal on the radio link. The UE (10) determines (401) that the received signal comprises a time synchronization message and a security extension associated with the time synchronization message. The UE (10) further determines (402) that the radio link is valid if a security mechanism related to the security extension indicates that the time synchronization message is valid. The UE (10) further determines (403) that the radio link is non-valid if the security mechanism related to the security extension indicates that the time synchronization message is non-valid.

摘要： The invention is concerned with improvements in mobile communications, and especially with improvements in bonding communications simultaneously utilising multiple mobile networks. It may be embodied in a mobile device (12a, 12b, 12c). The mobile device (12) has a plurality of mobile network interface units (22a, 22b, 22c) each of which is configurable to connect to each of a group of mobile networks (16a, 16b, 16c). The mobile device (12) comprises at least one digital processing device implementing allocation logic which allocates each mobile network unit to one of the mobile networks (16a, 16b, 16c) and causes each mobile network interface unit (22a, 22b, 22c) to be configured to connect to the network (16a, 16b, 16c) to which it is allocated. The allocation logic serves to allocate the mobile network units (22a, 22b, 22c) to the mobile networks (16a, 16b, 16c) based on operating parameters, and to re-allocate the mobile network interface units (22a, 22b, 22c) in response to changes in the operating parameters, causing the mobile network units (22a, 22b, 22c) to be re-configured such as to disconnect from one mobile network and connect to another mobile network.

摘要： Apparatus, methods, and computer-readable media for facilitating detection of false base stations based on signal times of arrival are disclosed herein. An example method for wireless communication of a UE includes receiving a signal from each of one or more neighboring base stations. The example method also includes determining a system timing associated with the wireless communications network based on a respective time of arrival at which each signal is received from the one or more neighboring base stations. The example method also includes receiving a signal from an FBS, the FBS signal being associated with a PCI different than the PCIs associated with the signals received from each of the one or more neighboring base stations. Additionally, the example method includes identifying a presence of the FBS based on a difference between the system timing and a time of arrival at which the signal is received from the FBS.
