The present disclosure relates to a network access method, which belongs to the technical field of smart homes. The method includes: after short-distance wireless communication is established between a smart home device and a terminal, the terminal receiving access requirement information transmitted by the smart home device; the terminal determining a target base station according to the access requirement information; the terminal transmitting access information for accessing the target base station to the smart home device; and the smart home device initiating a random access to the target base station according to the access information, such that the smart home device accesses a cellular mobile network.

A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The tunnel device is selected based on an attribute, such as IP Geolocation. A tunnel bank server stores a list of available tunnels that may be used, associated with values of various attribute types. The tunnel devices initiate communication with the tunnel bank server, and stays connected to it, for allowing a communication session initiated by the tunnel bank server. Upon receiving a request from a client to a content and for specific attribute types and values, a tunnel is selected by the tunnel bank server, and is used as a tunnel for retrieving the required content from the web server, using standard protocol such as SOCKS, WebSocket or HTTP Proxy. The client only communicates with a super proxy server that manages the content fetching scheme.

Provided are a wire harness, a connector and a communication relay method with which effects such as reduction in the relay processing load of an in-vehicle device or improvement in the scalability of an in-vehicle device can be expected. A wire harness according to an embodiment includes a connector to be detachably connected to an in-vehicle device, a plurality of communication lines connected to the connector, and a relay unit provided in the connector and configured to relay communication between the plurality of communication lines and to relay communication between the communication lines and the in-vehicle device.

A cable modem system for discovering interference groups (IGs) includes an infrastructure and a cable modem termination system (CMTS). The infrastructure is for transferring data. The CMTS is configured to initiate generation of test signals by a set of cable modems (CMs), obtain a set of test measurements for the set of CMs, discover interference groups (IGs) of the set of CMs based on the obtained set of test measurements and assign a plurality of upstream and downstream channels for the set of CMs that use orthogonal frequency division multiplexing (OFDM) based on the discovered IGs.

The present teachings is generally directed to systems and methods for facilitating communications with a satellite. In some embodiments, a request to communicate with a satellite may be received from a client device, and upon determining that a device identifier associated with the client device is associated with an account authorized to connect to one or more satellite ground stations, a schedule of activity for the account may be retrieved. The schedule of activity may indicate a time period that the client device is authorized to connect to the satellite ground station(s) such that data is communicated between the satellite and the client device, and the satellite ground station(s) may be configured to communicate with the satellite. At a start of the time period, a connection between the client device and the satellite ground station(s) may be generated, and via the connection, data may be provided to the client device.

Aspects relating to data transmission are described herein. In an implementation, in a method for data transmission, a tunneling protocol header is appended to a payload to obtain an encapsulated data packet, and at least one field is modified in the tunneling protocol header to indicate at least one of an access network (108) and a core network (108) for transmitting the encapsulated data packet, and the access network (108) and the core network (110) belong to different communication networks (104). Further, based on the tunneling protocol header, the encapsulated data packet is delivered to a routing unit for transmission.

A novel method of operating a Distributed Cable Modem Termination System is provided. Each branch CMTS node in a distributed CMTS supports a complete CMTS system and with full-spectrum ports. One or more MAC domains are defined at each branch CMTS node. A MAC domain defined at a branch CMTS node includes only service flows of the CMs that are connected to the branch CMTS node. Identifiers of service flows coming from a branch CMTS node are always unique, i.e., two different service flows of the branch CMTS would always have different SIDs, even if they belong to different MAC domains. On the other hand, service flows belonging to different branch CMTS nodes are free to reuse the same identifiers.
