  • Patent number: 10264497
    Abstract: Methods and arrangements in a base station and a User Equipment are provided. The methods and arrangements relates to the scenario when the UE is handed over from a source base station to a target base station in a handover scenario, and wherein the target base station may not support functionalities which the source base station and the UE support. The method in the UE comprises receiving (501) a configuration message from the target base station via the source base station, configuring (502) the UE based on the received configuration message from the target base station by searching (503) for a second field in an information element of the received configuration message. The presence/non-presence or a value of the second field is indicative of how to manage a configured first functionality associated with an optical first field, wherein the configured first functionality may not be supported by the target base station.

  • Patent number: 10237795
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication. A user equipment (UE) device may be connected to a first evolved packet data gateway (ePDG) via a first radio access technology (RAT). The UE may evaluate, either periodically or based on a trigger event, an ePDG reselection metric associated with the first ePDG to determine whether selecting a second ePDG different from the first ePDG is viable. The UE may then reselect to a second ePDG based on whether the ePDG reselection metric satisfies one or more selection conditions. Selection conditions may include, for example, a change in the location or public land mobile network (PLMN) of the UE, UE movement between networks, or a connection failure associated with the first ePDG.

  • Patent number: 10231158
    Abstract: A Machine-to-machine (M2M) terminal (11) comprises a radio communication unit (111) and a controller (112). The radio communication unit (111) is configured to communicate with a base station (13). The controller (112) is configured to change at least one of a cell selection operation, a cell reselection operation, and a handover operation according to whether a specific coverage enhancement processing is required or according to whether the specific coverage enhancement processing is supported by at least one of a cell (13) in which the M2M terminal (11) camps on and a neighboring cell (14) of the cell (13) which the M2M terminal (11) camps on. It is thus possible to provide an improved technique for allowing the M2M terminal that is supporting a special coverage enhancement processing for M2M terminals to camp on an appropriate cell.

  • Patent number: 10231152
    Abstract: The present invention discloses a network handover method, where after UE in an LTE network requests circuit switched fallback CSFB, an MME instructs an eNB to move the UE from the LTE network to a 2G or 3G network, and requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network for the CSFB, so that the 2G or 3G network allocates a CS domain resource to the UE. After handing over to the CS domain, the UE may perform a CS domain call. By using embodiments of the present invention, an access delay is reduced when the UE accesses the CS domain of the 2G or 3G network, duration of an entire voice call is shortened, and user experience is improved.

  • Patent number: 10225340
    Abstract: A computer-implemented method is provided for transparently optimizing data transmission between a first endpoint and a second endpoint in a computer network. The endpoints have a directly established data session therebetween. The data session is identified by each endpoint at least to itself in the same way throughout the session. The method includes the steps of: relaying data between the endpoints transparently in the session using a network optimization service; and transparently modifying or storing at least some of the data transmitted from the second endpoint to the first endpoint using the network optimization service in order to optimize data communications between the endpoints, wherein transparently modifying at least some of the data comprises changing the data, replacing the data, or inserting additional data such that the first endpoint receives different data than was sent by the second endpoint.

  • Patent number: 10219154
    Abstract: A system and method for the secure frictionless or near-frictionless authentication of a user's identity resulting in a determination signal that the user is who they claim to be, access granted, or is not who they claim to be, access denied. In one embodiment, a user accesses the login page of a website and, after a short pause, is granted access to a restricted website resource, for example their bank account. During the short pause signals are exchanged over a triad of telecommunication networks, from the webserver to an App on the user's cellphone where credentials and probability of possession are collected, encrypted and sent over near proximity network to the device being used to make the original login request that in turn forwards the accumulated authentication tokens to the webserver for verification. Upon success of the verification the user is granted access to the restricted resource, in this example, their bank accounts.
