  • Publication number: 20210092706
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for encrypting paging information transmitted to a user equipment (UE) in a paging message. In one aspect, a base station (BS) encrypts paging information and transmits a paging message to one of a UE or another BS for transmission to the UE. The paging message includes the encrypted paging information. A UE receives the paging message from a BS including the encrypted paging information. The UE decrypts the encrypted paging information to identify paging information, and determines whether to communicate with the BS based on the paging information. The paging information may be encrypted and the encrypted paging information decrypted based on information configured or obtained during at least one of a registration procedure or a radio access network (RAN)-based Notification Area Update (RNAU). Confidentiality of paging information in paging messages may thereby be improved.

  • Publication number: 20210084707
    Abstract: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

  • Patent number: 10952051
    Abstract: Connectionless data transfer is disclosed. Authentication of a device and network node may be performed when data is sent from the device to an application server of an application service provider via a selected network. The transfer of data may take place in an absence of an existing device context between the network node interacting with the device and the core network through which the data travels. State management overhead and signaling overhead may be reduced by use of the exemplary aspects disclosed herein. For example, the device does not need to perform an authentication and key agreement (AKA) procedure to transfer the data and an existing (or pre-existing) device context need not be maintained at the core network.

  • Publication number: 20210063895
    Abstract: A method of determining a marker layout for a semiconductor device includes determining the number of markers to be used in a field of a wafer using a first fitness function, calculating a marker probability distribution considering distance information among the markers and determining locations of a marker to be used according to the marker probability distribution, and evaluating performance of a final marker layout by using a second fitness function. The method provides an optimized approach to marker layout, so that the quality of a marker layout may be enhanced. Also, the method generates a marker layout that may minimize a prediction value of an overlay error of experimental wafers and an irregularity of marker locations, so that robust performance may be ensured for the prediction of overlay errors for subsequent new wafers.
