Systems, methods and devices for location-based services are disclosed in the present invention. A multiplicity of network devices, a database, and a server platform in network-based communication. The database stores a space-network model binding IP addresses and physical locations. The server platform is operable to generate at least one geofence in the space-network model and specify entitlements for the location-based services within the at least one geofence. The at least one geofence and specific entitlement are stored to the database. The multiplicity of network devices are configured to learn the space-network model and the at least one geofence and perform tasks based on the entitlements specified for the location-based services within the at least one geofence.

Disclosed are a system and data card for stateless automatic configuration of an IPv6 address and the method for implementing the same, and the method includes: an IPv6 address configuration way of a data card is set and stored according to an IPv6 address allocation strategy of a current network, after successful establishment of an IPv6 dialup connection and reception of a router advertisement request message transmitted by a terminal for acquiring a prefix address, the data card determines the set IPv6 address allocation way, and when the set IPv6 address allocation way is a static configuration way, a router advertisement response message is discarded and a valid IPv6 global unicast address is reported to the terminal. By means of the system, data card and method, it is possible to solve a problem that data transmission can not be normally performed by an existing data card implementing dialup in an Ethernet link way when interface identifiers are allocated by a network.

IPv6 address assignment method and apparatus are provided. The method includes: receiving first Prefix Delegations (PDs) sent by at least two network access devices, where the first PDs sent by the different network access devices are different from each other; generating second PDs according to the received first PDs, where the second PDs have a one-to-one correspondence with the first PDs; and sending the generated second PDs to user device for generating by the user device IPv6 addresses according to the second PDs.

A method for automatic address configuration, router, computer program, computer-readable medium and method for automatically configuring a router that has an upstream interface, connected or connectable to a higher-level subnetwork and/or a higher-level router, and a downstream interface, connected or connectable to a lower-level subnetwork, wherein whether the router receives, on the upstream interface, messages providing notification of at least one domain as part of a DNS search list option, is monitored and, if the message is not received over a prescribed period, a DNS island mode is automatically activated in which the DNS zone of a local DNS server of the router is configured using a predefined island domain, and a transmission module of the router is prompted to send a message via the downstream interface, which message includes the preconfigured island domain as part of a DNS search list option, preferably an address of the downstream interface.

An Internet-of-Things (IoT) system for public transportation service and a method of operating the same are disclosed. The IoT system includes on-vehicle devices, a management server, a plurality of bus stop access points (APs), and a wired/wireless bus stop access point (AP) communication network. The on-vehicle devices are mounted within a bus, i.e., a public transportation means. The management server is connected to the bus over an Internet, i.e., a wireless communication means. The plurality of bus stop APs are short distance communication APs, and are each provided in each bus stop at which the bus stops and configured to enable information to be exchanged between the bus stop and the bus. The wired/wireless bus stop AP communication network connects the plurality of bus stop APs. The management server performs Internet access processing to connect the bus stop AP communication network and an external terminal.

Embodiments disclosed herein provide systems, methods, and computer readable media for extending the lifetime of a network address when an address system is unavailable. In a particular embodiment, a method provides, upon determining that a first network address for a network element has reached a preferred lifetime for the first network address, transitioning the network element to an extended rebind state that allows the first network address to remain in the preferred state. While the network element is in the extended rebind state, the method provides attempting to contact an address system and determining whether a second network element is assigned the first network address. The method further provides maintaining the first network address in the preferred state and the network element in the extended rebind state until contact is made with the address system or the second network element is determined to be assigned the first network address.

A scheme for providing access to 6LoWPAN data in a wireless access network comprising a Digital Unit (DU) coupled to one or more Radio Units (RU) via CPRI links, each RU in turn coupled to one or more radio dot (RD) elements via Ethernet cable links. In one embodiment, an RD element includes a cable front-end interfaced with the Ethernet cable link, a radio front-end interfaced between the cable front-end and an antenna or a suitable access point. A sensor component may be included that is configured to generate sensor data with respect to a measurement variable, which sensor data may be packaged in a 6LoWPAN data format for transmission to the RU element coupled to the RD element.

A segment identifier (SID) manager interfaces with clients by way of a library. Clients implementing network services and needing SIDs according to internet SRv6, are allocated blocks by the SID manager using the library. Clients assign SIDs from the block independent of the SID manager using the library. Where a threshold portion of the block is assigned, the library requests an additional block of SIDs from the SID manager. Clients transmit context mappings of assigned SIDs to the SID manager for use by administrators and to enable recovery in the event of failure.

Apparatus, system and method for authenticating a device for secure network communication. A device may obtain identification data in the device, wherein the identification data is configured as a hash of a public key for identifying at least one of the device and/or a user associated with the device. An Internet Protocol (IP) message may be generated, wherein an IP source address in the IP message includes the identification data. The device may register with a server by transmitting the IP message and the public key and subsequently generate and transmit a second IP message after registering the device, wherein an IP source address of the second IP message includes the identification data. The server may issue a challenge to the device in response to the second IP message, wherein the challenge is based at least in part on the identification data. After receiving the challenge, the device may transmit response data to the server for authenticating the device for secure network communication.

Configuration of tunnel, firewall and/or other positional based functionality for routers operating within a multi-router network is contemplated. The functionality configured for one or more of the routers may be implemented automatically without manual input or identification, such as to facilitate an off-the-shelf implementation process where positioning and attendant functionality is routinely implemented according to a predefined set of roles.
