  • Publication number: 20210126888
    Abstract: Methods, central unit (200A) and distributed unit (200B) of a radio network node (200), for handling a message received from a core node (204) for transmission to a wireless device (202). An action is required by the radio network node if the message is not successfully delivered to the wireless device. The central unit (200A) sends the message and an associated identifier I_msg to the distributed unit (200B) and then receives feedback indicating whether the message has been successfully delivered to the wireless device or not. The central unit (200A) performs the required action if the feedback does not confirm delivery of the message to the wireless device (202). The required action may include sending a non-delivery indication to the core node (204).

  • Publication number: 20210007175
    Abstract: A network node (300a) receives, over an interface between the network node (300a) and a further network node (300b), a message comprising paired user equipment (UE) identifiers for UE identification over the interface to the network node (300a) and further network node (300b), respectively. Responsive to determining that the identifier for UE identification to the network node (300a) uniquely identifies a UE (150) to the network node (300a), the network node (300a) validates the message irrespective of whether the identifier for UE identification to the further network node (300b) uniquely identifies the UE (150) to the further network node(300b).

  • Publication number: 20200305235
    Abstract: Embodiments include methods, performed by a first radio network node (RNN) in a wireless network, to establish a communications interface with a second RNN in the wireless network. Such methods include receiving, from a third RNN in the wireless network, a Transport Network Layer (TNL) address associated with the second RNN. The first and third RNNs are configured for wireless communication with wireless devices via an E-UTRA radio access technology (RAT), and the second RNN is configured for wireless communication via an NR RAT. The third RNN can be a proxy node for discovery of TNL addresses associated with a plurality RNNs configured for wireless communication via the NR RAT. Such methods include establishing the communications interface with the second RNN based on the TNL address received from the third RNN. Other embodiments include complementary methods performed by a second RNN, and RNNs configured to perform such methods.

  • Patent number: 10222451
    Abstract: Disclosed is a method performed by a position calculation node (160) in a wireless communication network (100). The node (160) is arranged for improving accuracy when determining positions in the wireless communication network. The method comprises obtaining a signal transport time value for each of a plurality of different geographical UE positions (UE1, UE2, UE3), wherein the respective signal transport time value relates to the time it takes for a radio signal to travel between a first base station and one of the plurality of UE positions. The method further comprises obtaining a geographical position value for each of the plurality of different geographical UE positions, the position values being independent of the signal transport time values, and determining an actual geographical position for the first base station, based on the obtained signal transport time values, the obtained position values and a predefined geographical position for the first base station.
