The present disclosure provides methods for link selection in a telecommunication system, a user equipment, a network node, and a telecommunication system. The method comprises: communicating a probing message with a second UE via a relay link therebetween, both of the UEs being served by a same network node; determining whether uplink (UL) data is to be transmitted to the network node via the relay link or via an access link between the UE and the network node at least partially based on the link quality of the relay link, which is determined at least partially based on the probing message, and the link quality of the access link, or based on an indication from the network node; and transmitting the UL data via the determined one of the relay link and the access link.

A multi-band network node has selectable backhaul/fronthaul configurations. Network nodes provide multi-band operation to take advantage of higher Internet speeds and to support lower latency (> 2 Gbps, < 4 ms latency) applications. A greater Wi-Fi device count (capacity) is supported by implementing communication over additional bands. Increased bandwidth is made available between connected nodes by selectively combining backhaul throughputs. Hardware quality-of-service (QoS) is provided by splitting traffic flows for low latency and data applications. Network coverage is extended by dynamic assignment of backhaul connections and by configuring unused backhauls as fronthauls.

A relay User Equipment (UE) determining method and a device are provided. The relay UE determining method includes: obtaining relay-related information corresponding to each candidate UE in at least one candidate UE; and performing relay UE selection or relay UE reselection according to the relay-related information corresponding to each candidate UE.

An application acceleration method includes identifying a data packet to be transmitted by an application running on a mobile terminal as a data packet to be accelerated to an application server, and determining network communication qualities of a first network transmission path to an access node via a wireless LAN communication network and a second network transmission path to the access node via a mobile network. The method further includes selecting a network transmission path based on network communication quality from the first network transmission path and the second network transmission path, and transmitting the data packet to the access node via the selected network transmission path such that the access node transmits the data packet to the application server through the network acceleration channel. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

Systems and methods for routing messages are disclosed herein. The methods can include maintaining, at a computing system, a plurality of completion rates, wherein each completion rate is associated with a communication network. The methods can also include receiving, from a service provider, a request to authenticate an end user of the service provider, generating an authentication message, and selecting, based on the maintained completion rates, a communication network from a plurality of communication networks. The methods can further include transmitting the authentication message to a device associated with the end user using the selected communication network, receiving an indication that the end user performed an action in response to receiving the authentication message, determining whether the end user has been authenticated based on the end user’s action, and updating the maintained completion rate associated with the selected communication network based on the determination.

Devices of a control system may communicate with each other via a network. The control devices may be configured to form the network by joining the network and each attempt to attach to another device on the network. Attachment may be performed using one or more link quality thresholds. For example, the control device may measure background values and the link quality threshold may represent an N.sup.th percentile value of the recorded background values measured at the control device. During a router optimization mode, the control devices may measure and store a communication quality metrics that may be used to assign the role of router devices and/or the role of leader device to control devices on the network.

The present invention relates to an IPv6 wireless sensor network node mobility management method based on RPL routing protocol. The present invention achieves the following: first, placing an RSSI in an ACK frame so as to detect the mobile state of a node and improve the accuracy of mobile detection; second, on the premise of compatibility with an original RPL routing protocol, improving the options for DIS and DAO in selecting the optimal parent node and updating a routing table; and finally, designing a cache method to prevent messages sent to the mobile node from being lost in the process of moving, and designing a new 6LoWPAN header so as to complete message caching.
