  • Patent number: 11968295
    Abstract: Methods, terminal and a data center gateway are provided for allowing efficient debugging and troubleshooting of data session encrypted with Perfect Forward Secrecy (PFS) encryption techniques such as for example the Transport Layer Security (TLS) protocol version 1.3. Embodiments of the invention allow the user terminal to authorize a data center gateway to persistently store one or more encryption keys associated with the data session for use to access the recorded data session and troubleshooting it after the session ended, when faults are detected. When a fault is detected, the user terminal provides authorization to the gateway to persistently store the data session along with one or more encryption key(s). With this, the gateway allows for the data session to be later decrypted and faults to be investigated despite the data session being encrypted with PFS techniques.

  • Patent number: 11968535
    Abstract: The present disclosure relate to a method performed by a UE (102) for handling an invalid SI signature in a communication system. The UE obtains SI and an associated SI signature for a cell. The UE (102) determines if the obtained SI signature is valid or invalid. If the signature is valid, the UE (102) determines to use the cell. If the SI signature is invalid, the UE (102) determines if the UE (102) is configured to bar cells or not. If the SI signature is invalid and if the UE (102) is not configured to bar cells with invalid SI signature, the UE (102) determines to use the cell. If the SI signature is invalid and the UE (102) is configured to bar cells with invalid SI signature, the UE (102) determines to bar the cell and select another cell to use.

  • Patent number: 11968586
    Abstract: A network node of a wireless communication network provides information to a User Equipment (UE) that allows the UE to adapt it radio measurements with respect to the network, to account for “link changes.” Link changes are service-link and/or feeder-link changes arising from motion by the satellite(s) included in the Radio Access Network (RAN) portion of the network. The UE uses the provided information to adapt its radio measurements in conjunction with the link changes. Among the several advantages of accounting for satellite link changes in the manner contemplated are any one or more of reduced signaling going between the UE and the network, reduced battery consumption at the UE, mitigation of the effects of the link changes on the radio measurements, avoidance of spurious measurements, and an effective “automation” of the timed changeover by the UE to new measurement configurations, coincident with the occurrence of link changes.

  • Patent number: 11968547
    Abstract: A base station or other network node configures a network transmission in dependence on a directional scanning reception ability of a wireless communication device targeted by the transmission. An example transmission configuration is selecting or restricting which Transmission/Reception Point to use for the transmission or selecting or restricting the beamforming configuration to use for the transmission. The device complements operations in the wireless communication network by indicating its directional scanning reception ability in initial signaling, such as used for random access, or in Radio Resource Control signaling, or both.
