  • Patent number: 11968729
    Abstract: Embodiments of the present disclosure relate to a method and an apparatus for allocating a PDU session ID for a terminal device. The method comprises: selecting (S101), for a terminal device, a protocol data unit session identity, PDU session ID, from a group of PDU session IDs. The group of PDU session IDs are not allocated to the terminal device. According to the embodiments of the present disclosure, the network node may select, for the terminal device, a PDU session ID from a group of PDU session IDs, which are not allocated to the terminal device yet.

  • Patent number: 11968385
    Abstract: An object of the embodiments is to achieve an improved reference picture handling. That is achieved by taking into account whether the reference pictures in the decoded picture buffer are long-term reference pictures or short-term reference pictures when determining how they should be marked when the information of the reference picture set is received. The reference pictures are marked as “used for short-term reference” or “used for long-term reference” in the Decoded Picture Buffer (DPB) depending on whether they are included as short-term pictures or long-term pictures in the RPS of a current picture.

  • 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: 11968588
    Abstract: Embodiments include methods performed by a network node, in a radio access network, RAN, that is a target node candidate for a mobility operation of a user equipment, UE. Such methods include receiving, from a source node serving the UE, a request to prepare a mobility procedure for the UE in relation to a candidate target cell associated with the network node. The request can include characteristics associated with a data connection of the UE. Such methods include determining that the UE can be admitted for the requested mobility procedure based on the characteristics, and determining to activate bicasting of the data connection. Different bicasting modes can be selected. Such methods also include transmitting, to the source node, a response that includes a bicasting configuration associated with the UE. Other embodiments include complementary methods performed by source nodes, as well as network nodes configured to perform such methods.

  • Patent number: 11967327
    Abstract: A method and a decoder device of generating a concealment audio subframe of an audio signal are provided. The method comprises generating frequency spectra on a subframe basis where consecutive subframes of the audio signal have a property that an applied window shape of first subframe of the consecutive subframes is a mirrored version or a time reversed version of a second subframe of the consecutive subframes. Peaks of a signal spectrum of a previously received audio signal are detected for a concealment subframe, and a phase of each of the peaks is estimated. A time reversed phase adjustment is derived based on the estimated phase and applied to the peaks of the signal spectrum to form time reversed phase adjusted peaks.

  • 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: 11968571
    Abstract: A method performed by a target node (111) in a communications network (100). The method is for handling reconfigurations of a User Equipment (UE) (120) during a conditional handover. The target node (111) has received a conditional handover request for the UE (120) from a source node (110) and has sent a handover request acknowledgement to the source node (110) based on a current configuration of the UE (120). The target node (111) performs (401) synchronization and random access with the UE (120) based on the UE configuration used for the handover request acknowledgement. The target node (111) obtains (403), after performing (401) the synchronization, information regarding an updated configuration of the UE (120). The updated configuration has taken place since the handover request acknowledgement was sent to the source node (110).
