A reference signal periodically transmitted by a base station in a wireless network can have certain proprietary properties to help prevent detection and utilization of the signal for unauthorized positioning of mobile devices. More specifically, a network node can obscure and introduce time-variation in mapping between positioning signals and a corresponding physical base stations. The network node may also introduce time variations in fields of a base station almanac (BSA) provided to subscribing user equipments (UEs). The information transmitted to the subscribing UEs may be encrypted.

Embodiments include methods for a target node to establish a connection with a user equipment (UE) operating in dual connectivity (DC) with a PCell utilizing a first radio access technology (RAT) and with a PSCell utilizing a second RAT. Embodiments include receiving, from the UE, a re-establishment request message comprising parameters associated with the PSCell, a first message authentication code (MAC), and an indication of the UE's selection of a target cell served by the target node as a replacement for the PCell. The target cell utilizes the second RAT. Embodiments include verifying the message integrity based on the first MAC, and determining a full UE context based on the plurality of parameters associated with the PSCell and on a successful verification of the message integrity. Embodiments include establishing a connection with the UE based on the full UE context, whereby the target cell serves as a PCell for DC.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure discloses a terminal including a transmission and reception unit and at least one processor. The at least one processor controls the transmission and reception unit so that the transmission and reception unit receives a message such as an SMS, an MMS, or an OTT including event download information from a communication operator server, searches for event download information from the received message such as the SMS, the MMS, or the OTT, transmits the event download information to another terminal if necessary, and receives an event from a profile server with reference to the event download information.

The present disclosure provides a method and system for data transmission, chip, an electronic device, and a computer readable storage medium. The method applied at a first Bluetooth end includes: establishing a point-to-point connection with a second Bluetooth end; acquiring identity information of the second Bluetooth end through the point-to-point connection; and sending broadcast isochronous group information BIGInfo to the second Bluetooth end through the point-to-point connection when the identity information of the second Bluetooth end is verified, to enable the second Bluetooth end to receive a data stream of a broadcast isochronous group BIG sent by the first Bluetooth end according to the BIGInfo.

Systems and methods for securing user location data are described. A method includes receiving, by a location server computer, an encrypted location from a mobile device. The encrypted location is a location of the mobile device encrypted with a public key. The method then includes receiving, by the location server computer, a location request message from an interaction processing server and partially decrypting, by the location server computer, the encrypted location with a first private key share to form a partially decrypted location. The method further includes transmitting, by the location server computer to the interaction processing server, a location response message with the encrypted location and the partially decrypted location. The interaction processing server then uses the partially decrypted location and the second private key share to form a decrypted location.

Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.
