Methods and an apparatus for providing an edge computing service to a UE in a mobile communication network and. The method comprises: receiving, from an AMF, a PDU session modification command including first information instructing modification of a PUD session for the MEC service and valid time of the PDU session; transmitting, to the AMF, a PDU session modification command NACK message including second information indicating a wait until transmission of an ACK, when relocation of an application context corresponding to the PDU session is possible within the valid time of the PDU session; transmitting, to an MEC system providing the service, an application context relocation request message; and transmitting, to the AMF, a PDU session modification command ACK in response to receiving an application context relocation complete message from the MEC system, wherein the PDU session modification command and the PDU session modification command NACK message are NAS messages.

A method to assist with processing distributed jobs by retrieving and/or synchronizing supplemental job data. The method includes receiving a request pertaining to a job from a first virtualized execution environment using a non-persistent connection between the first virtualized execution environment and a second virtualized execution environment, transmitting, by the secondary machine using a persistent connection between the first virtualized execution environment and the second virtualized execution environment, a task request for supplemental information pertaining to the job, generating a job result for the job based on the supplemental information received from the first virtualized execution environment via the persistent connection, and transmitting, to the first virtualized execution environment, the job result for the job using the non-persistent connection.

A network combining wireless and wired elements is described, using a multi-slot modular mesh node to house diverse transceiver elements (e.g. IR, Wi-Fi, Powerline). A radio agnostic tree based mesh network is formed, based on what type of wireless links are formed on the uplink and downlink of the backhaul and what type of radios are used for the Access Points AP. In addition to servicing IP based clients (e.g. Wi-Fi, WiMax, Bluetooth), the modular mesh nodes APs may also serve as receivers/collectors for low cost chirp devices. The method of transport is standard IP based packets yet security is inherent in this chirp-based implementation: only mesh nodes are privy to the routing tables that indicate that packet addresses are not IP. Multiple methods to obfuscate packet flow are presented. An organic approach to providing category/class based form of data type identification is proposed, to support a (dynamic) M2M Social Network Applications in-device discovery, registration and control are presented.

A method for waking up devices in batches where the method includes generating, by a coordinator, a wake-up broadcast frame, where the wake-up broadcast frame includes a wake-up indication field, which instructs multiple devices in a low-rate wireless personal area network (LR-WPAN) to keep in a running state, and sending, by the coordinator, the wake-up broadcast frame at a time interval T2 within duration T1. Hence, the coordinator can wake up some devices directionally using the wake-up indication field in the wake-up broadcast frame. Therefore, resource utilization and wake-up efficiency of the coordinator are improved such that channel utilization and performance of the LR-WPAN are improved.

A network device may obtain policer configuration information. The network device may determine, based on the policer configuration information, a traffic rate limit associated with a traffic protocol type. The network device may obtain, based on the traffic protocol type, networking data associated with the traffic protocol type. The network device may determine, based on the networking data, an expected traffic rate associated with the traffic protocol type. The network device may update, based on the expected traffic rate, the traffic rate limit. The network device may cause traffic associated with the traffic protocol type to be policed based on the updated traffic rate limit.

A display device and a method of operating the same are provided. The display device includes: a display; a communicator configured to perform communication with a server via a wireless network; and a processor configured to execute at least one instruction to: receive a first packet from the server by communicating with the server to perform a first keep-alive operation according to a first communication protocol, generate and transmit, to the communicator, a second packet for performing a second keep-alive operation according to a second communication protocol with the server, based on data included in the received first packet, and control the display device to enter a suspend mode after transmitting the second packet, wherein the communicator is further configured to, while the display device is in the suspend mode, perform the second keep-alive operation by transmitting the second packet to the server at intervals of a first period.

Provided are an IoT device and an IoT communication method. The IoT device may: be connected to a server via NAT; execute a first session for service connection; and execute a second session for calculating a particular keep-alive value corresponding to a period in which an IP address mapped by the NAT expires. The present invention can minimize transmission of a keep-alive value of an IoT device, enables an IoT device to share a particular keep-alive value with other IoT devices, and thus can minimize a network load which may be caused by a keep-alive value of an IoT communication device.

Methods, systems and computer program products are provided for service to service SSH with authentication and SSH session reauthentication. A client service initiates an SSH session by automatically providing authentication information to an authentication provider service, which returns access information. The client service uses an SSH client to automatically provide the access information to an SSH server, which receives and validates the access information. A service-to-service SSH session is created between the SSH client and SSH server. The client service and a server service may communicate securely via the service-to-service SSH session. Security may be maintained for any type of SSH connection (e.g., user to service, service to service) by periodically and automatically providing and validating reauthentication and refresh information. AN SSH connection/session is maintained if periodic access information is validated. AN SSH connection/session is terminated if periodic access information is not provided in a refresh interval or is invalid.

A method and system directed to performing account activity tracking is provided. More specifically, user activity associated with a user's first account may influence when a user's second account is signed out due to inactivity. Accordingly, an activity request including a first identifier associated with a first user account may be received from a first entity, and based on the first identifier associated with the first user account, a second identifier associated with a second user account may be retrieved, where the first identifier and the second identifier are linked to one another. Activity information for the second identifier associated with the second user account may be obtained which may be provided to the entity. A decision as to whether or not to keep the user signed in may be based on the activity information.
