  • Publication number: 20210195509
    Abstract: A communication device, network node and methods therein in for handling network slices in a wireless communication network are disclosed. The communication device encrypts Network Slice Selection Assistance information, NSSAI, using public key cryptography and includes the encrypted NSSAI in a Non Access Stratum, NAS, registration request. Then the communication device sends a Radio Resource Control, RRC, request to the network node including the NAS registration request. The network node receives the RRC connection request from the communication device and selects a network function based on information in the RRC connection request. The network node forwards the NAS registration request to the network function and forwards to the communication device a NAS registration response received from the network function after the network function decrypting the NSSAI using a PLMN private key.

  • Publication number: 20210058827
    Abstract: In one aspect, a device, operating in an access network that can provide a plurality of QoS levels for user data flowing to and from the device, establishes a packet data session via the access network and receives, from the access network, cost information associated with each of one or more QoS levels. The device selects, for user data for at least a first application or service, a QoS level from among the plurality of QoS levels based on the cost information. The device transmits packets carrying user data for the first application or service to the access network. The transmission includes applying a QoS treatment to the user data according to the selected QoS level.

  • Publication number: 20210006562
    Abstract: The embodiments herein relate to a method in a mobility management node (108) for handling overload in a communications network (100). When overload in the communications network (100) has been detected, the mobility management node (108) receives information indicating at least one blocked IP address to which access should be blocked. The mobility management node (108) receives a communication request message from a UE (101) via a RAN node (105). The communication request message is a request for communication by the UE (101). The mobility management node (108) determines that the UE's (101) request for communication should be rejected when the UE (101) is associated with a blocked IP address.

  • Patent number: 10887927
    Abstract: A method performed in a communications network includes receiving, from a wireless communication device, such as for example, a user equipment (UE), an indication including the EPS bearer identity (EBI) the UE has determined to use for a pending uplink (UL) of user data. The indication indicates a preference of the UE to use an existing CP connection or to establish a UP ON connection for the pending UL of user data. The indication is included in a Tracking Area Update (TAU) request initiated by the UE. The method further includes determining, in response to receiving the indication, that the user plane (UP) connection does not need to be established and that the existing control plane (CP) connection may be used. The method further includes, in response to determining that the existing CP connection may be used, allowing the UE to send the pending UL of user data on the existing CP connection.

  • Publication number: 20200404533
    Abstract: A method performed by a wireless device for enabling reflective Quality-of-Service, QoS, to a bi-directional communications flow in a wireless communications network is provided. The wireless device receives a downlink, DL, data packet of the bi-directional communications flow indicating that reflective QoS is to be applied. The wireless device then determines, based on the type of the bi-directional communications flow, that a first reflective QoS rule for filtering Uplink, UL, data packets of the bi-directional communications flow cannot be derived based on control information comprised in the DL data packet. The wireless device further obtains, based on the control information comprised in the DL data packet and the type of the bi-directional communications flow, a second reflective QoS rule for filtering UL data packets such that the control information comprised in an UL data packet is at least partly different from the control information comprised in the DL data packet.
