  • Patent number: 10321364
    Abstract: Systems and methods are disclosed for providing a network-instructed handover of a wireless device from a Wireless Local Area Network (WLAN) to a Radio Access Network (RAN) of another Radio Access Technology (RAT), e.g., a 3rd Generation Partnership Project (3GPP) or 3rd Generation Partnership Project 2 (3GPP2) RAT. In one embodiment, a WLAN access node determines that a handover of a wireless device from the WLAN to another RAN of a different RAT is to be performed and transmits a handover instruction to the wireless device that instructs the wireless device to perform a handover from the WLAN to a RAN of a different RAT. In this manner, the WLAN access node is able to steer the wireless device from the WLAN to a RAN of a different RAT.

  • Patent number: 10313208
    Abstract: The disclosure relates to a method of resource allocation for supporting communications with a wireless device is provided. The method is performed in a network element of a wireless communication network. The method comprises differentiating (2710) between synchronous network functions and asynchronous network functions. The synchronous and asynchronous network functions are associated with the provision of communication services to the wireless device. The synchronous network functions have requirements on processing timing which are strictly dependent on timing of a radio link used for communicating with the wireless device. The asynchronous network functions have requirements on processing timing not strictly dependent on the timing of the radio link. The method also comprises allocating (2720) resources of the wireless communication network for the instantiation of a first network function based on whether the first network function is synchronous or asynchronous.

  • Patent number: 10230534
    Abstract: A method and apparatus for handling control signalling between a service layer control node and a Radio Access Network, the signalling being associated with a data flow of a User Equipment, the User Equipment being associated with a Radio Access Network node. The Radio Access Network node receives a data flow comprising a plurality of data packets sent using a bearer towards the User Equipment. It determines whether a data packet in the data flow includes an identifier indicating that the data packet relates to control signalling. A data packet that is found to relate to control signalling is removed from the data flow, to produce a modified data flow, which is sent towards the User Equipment. This allows the Radio Access Network node to become aware of control related signalling such that it can be processed.

  • Patent number: 10212753
    Abstract: The present disclosure relates to a method performed in a radio communications network which is configured to enable multipath communication. The method comprises providing an explicit indication that a path within a multipath connection is a backup path prior to establishment on or handover to a radio link of the backup path, transmission of the explicit indication to the base station, where it is interpreted. This allows an early indication that the path is a backup path and allows the base station to handle and prioritise use of radio network resources and/or connection characteristics for the radio link. The explicit indication may be in the radio level signalling or in handover signalling.

  • Publication number: 20190045351
    Abstract: A method, performed by a RAN node, for enabling connection setup for a wireless device in a communication network comprising a first network which is a home network of the wireless device and a second network which is visited by the wireless device. The networks each comprise partitioned sets of functionalities, which sets of functionalities each belong to a network slice of the network, wherein a first set of functionalities in the first network belongs to a first network slice supporting the wireless device. The RAN node receives a first network identity for the home network, an identity of the first network slice supporting the wireless device in the home network and a second network identity for the second network, from the wireless device to retrieve an identity of a second network slice capable of supporting the wireless device in the second network to determine a second core network node.

  • 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.
