  • Patent number: 10321424
    Abstract: A method and nodes for wireless timing synchronization of a target node and a source node. In some embodiments, a request is sent to a source node for time synchronizing the target node with the source node. A first time, T1, indicative of time of transmission of a first radio signal from the source node to the target node is determined. A second time, T2, indicative of time of receipt of the first radio signal at the target node is determined. A third time, T3, indicative of time of transmission of a second radio signal from the target node to the source node is determined. A fourth time, T4, indicative of time of receipt of the second radio signal at the source node is determined. A clock offset based on T1, T2, T3 and T4 for use in time synchronizing the target node with the source node is determined.

  • Patent number: 10321382
    Abstract: There is provided a method, performed by a network node, for steering of access between cells. The method comprises receiving, from user equipment, a report indicating failure to access a cell, also referred to as a rejecting cell, due to internal reasons of another network node, also referred to as a rejecting network node, serving the rejecting cell. The method also comprises steering the access of the user equipment between cells by modifying at least one offloading parameter and/or threshold based on the report indicating failure to access the rejecting cell due to internal reasons of the rejecting network node serving the rejecting cell. With this new type of report the network can modify offloading parameter(s) and/or threshold(s) in a more suitable way since the network has more information available.

  • Patent number: 10299178
    Abstract: A first base station provides radio communication service to user equipments, UEs, and a second base station that provides radio communication service to UEs in adjacent cell service area. The first base station receives cell range expansion, CRE, information from the second base station for expanding the size of the first cell and evaluates handover of one or more UEs with respect to the second cell based on the CRE information. In one embodiment, the second base station determines a CRE related configuration that includes the CRE information with respect to the first cell, sends the CRE information to the first base station. For example, the second base station may send a handover request including the CRE information to the first base station. The second base station also may consider CRE information in handover evaluation.

  • Publication number: 20190082418
    Abstract: In case of an UE in an inactive state (RRC disconnected but Core Network connected), the Core Network cannot page the UE because this one is formally connected. The UE is therefore paged at RAN-level. In detail, the first Base Station that receives downlink data or control signalling for the UE, pages the UE. If the UE does not reply, the first Base Station requests second Base Stations to page the UE. If not found the request is enlarged from the second BS to further Base stations and so on until either the UE is found or a maximum number of hops is reached. The Base Stations trace then backwards the information that the UE has been paged until the first BS.

    Abstract: A first radio network node (208) and a method for establishing a communications interface between the first radio network node (208) and a second radio network node (210). The first radio network node is configured to provide one or more Evolved Universal Terrestrial Radio Access (E-UTRA) resources and the second radio network node is configured to provide one or more New Radio (NR) resources. Further, the first and second radio network nodes are operating in a wireless communications network (200). The first radio network node obtains a Transport Network Layer (TNL) address of the second radio network node from one out of a first core network node (204); and another first radio network node (208) acting as a proxy. Furthermore, the first radio network node established a communications interface between the first and second radio network nodes based on the obtained TNL address.

  • Publication number: 20190059039
    Abstract: A method may be provided to operate a CU node that is coupled with first and second DU nodes. Communication is provided between the CU node and a mobile communication device through the first DU node over a first radio link. A message is received at the CU node from the first DU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication between the CU node and the mobile communication device through the first DU node is suspended, wherein configuration of the first DU node to serve the mobile communication device using the first radio link is maintained. While suspending communication between the CU node and the mobile communication device through the first DU node, communication may be provided between the CU node and the mobile communication device through the second DU node over a second radio link.

  • Patent number: 10206148
    Abstract: Methods and apparatus for providing a handover of fewer than all bearers associated with a user equipment are disclosed. An example method includes establishing a connection for fewer than all bearers associated with the user equipment, via a selective handover procedure, and receiving, from a source base station or a user equipment, a handover completion message for the fewer than all bearers associated with the user equipment. The example method further includes sending, to a core network node, a request to switch a path for the fewer than all bearers, the request comprising an information element providing an indication of whether or not a control interface connection between the source base station and the core network node should continue to be maintained, and thus not switched to the target base station. In some embodiments, but not all, an acknowledgement message is subsequently received, in response to the request.

  • Publication number: 20190037531
    Abstract: A method performed by a core network node for handling communication for a wireless device in a communication network, wherein the communication network comprises partitioned sets of functionalities. A first set of functionalities belongs to a first network slice supporting the wireless device, and a second set of functionalities belongs to a second network slice supporting the wireless device, and which first and second sets of functionalities are separated from one another and other sets of functionalities. The core network node obtains a common identity for defining paging occasion for the wireless device for paging from the first network slice and the second network slice. The core network node receives a paging request for the wireless device from the first network slice when the wireless device is in idle mode, and the core network node initiates a paging procedure of the wireless device by using the obtained common identity.
