  • Publication number: 20190261232
    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.

  • Publication number: 20190190820
    Abstract: Methods for managing packets in a communication system based on Software Defined Networking are disclosed. The communication system's data plane comprises a forwarding module, a service module, and an entry module, and the communication system's control plane comprises a management module. The entry module receives an IP packet from the peer device, the IP packet including a destination IP address associated with the mobile device. The entry module obtains, from the management module, a location value specifying the radio network node associated with the destination IP address. The entry module associates the location value with the IP packet, wherein the location value is related to a location tag name, indicating the radio network node that serves the mobile device, thereby obtaining a packet. The entry module sends the packet, via the forwarding module, towards the radio network node as indicated by the location value of the location tag name.

  • Publication number: 20180352602
    Abstract: An access node of the cellular network determines a correlation of an identifier of a user equipment with an entry of a Pending Interest Table maintained by an Information Centric Networking node. The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request at the Information Centric Networking node. Based on the correlation, the access node controls a connection of the user equipment with the cellular network. This may involve deciding whether to release the user equipment to idle mode or paging of the user equipment.

  • Patent number: 10064120
    Abstract: The embodiments herein relate to a method performed by a control plane node (303) for handling a UE (101) which roams into a visited network (100a). At least the network in which the control plane node (303) is comprised is a MSC network. The control plane node (303) transmits a create chain request message to a service chain controller (305). The create chain request message is a request to create a chain of UPF nodes (308) that user plane packets to or from the UE (101) should traverse. The control plane node (303) receives a create chain response message from the service chain controller (305). The create chain response message indicates that the requested chain has been created.
