  • Publication number: 20200296775
    Abstract: A method for setting-up a tunnel connection for transporting data packets over a high latency network connection in a communication network comprises the step of, at a module or node configured on a tunnel connection initiator side of the high latency network connection, using a non-TCP connection to encapsulate a set-up connection message for sending to a module or node configured on a core network (CN) side of the backhaul network to offset-up a data packet transport tunnel connection between the initiator side of the high latency network connection and core network (CN) side of the high latency network connection.

  • Publication number: 20200183153
    Abstract: A head-mounted display (HMD) system includes an optical arrangement; a first image panel, wherein the optical arrangement directs image light from the first image panel along a first optical pathway; a second image panel, wherein the optical arrangement directs image light from the second image panel along a second optical pathway different from the first optical pathway; and a third image panel and a fourth image panel, wherein the third and fourth image panels are spaced apart from each other and the optical arrangement directs light from the third image panel and the fourth image panel along different optical pathways. The optical arrangement is configured such that light from the first image panel and the third image panel are emitted from the HMD system in a combined fashion in a first eye direction, and light from the second image panel and the fourth image panel are emitted from the HMD system in a combined fashion in a second eye direction different from the first eye direction.

  • Patent number: 10602426
    Abstract: Provided is a method of modifying a data path between a user equipment (UE) and a core network node (CNN) in a wireless communication network. The method comprises the steps of: at a network node handling both signalling messages and user data for an existing data path between said UE and said CNN, obtaining data uniquely associated with a data path resource for said UE and/or uniquely identifying said UE and mapping said data to said existing data path; and modifying said existing data path based on said mapping. The network node handling both signal messaging and user data for an existing data path may comprise a gateway (GW) connecting a source base station (SBS) and a target base station (TBS) to a Mobility Management Entity (MME) of the core network, said GW being configured to handle both user plane data and control plane data for a plurality of UEs.

  • Publication number: 20200081254
    Abstract: An optical system enables high image quality Head Mounted Displays to be made more compact and/or of reduced weight. The optical system includes at least two or more image panels per eye, two or more reflective surfaces per image panel, and a refractive eyepiece element. Light from each image panel is reflected by a distinct set of optical surfaces before reaching the eye, forming at least two overlapping virtual images per eye. The invention may allow the apparatus to have a compact form factor with weight distribution close to the user's face without compromising on image quality and resolution.

  • Patent number: 10064048
    Abstract: A gateway (GW) acquires an International Mobile Subscriber Identity (IMSI) of a user equipment (UE) without requesting a mobile management entity (MME) of a core network (CN) to provide it. The GW detects arrival of a S1AP message for the UE. If the GW does not have the IMSI of the UE, and if a NAS payload of the S1AP message is ciphered, send to the UE a rejecting message indicating detaching the UE from the CN, causing the UE to request re-attaching to the CN in a S1AP message that is an Initial UE Message, which contains a temporary identifier of the UE. Then alter the Initial UE Message with a fabricated temporary identifier not recognizable by the MME and send the altered message to the MME, causing the MME to ask the UE to identify itself with the IMSI, which is read by the GW.
