GPRS Tunnelling Protocol (GTP) is a group of IP -based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points. GTP can be decomposed into separate protocols, GTP-C, GTP-U ...
An immersed tube (or immersed tunnel) is a kind of undersea tunnel composed of segments, constructed elsewhere and floated to the tunnel site to be sunk into place and then linked together. They are commonly used for road and rail crossings of rivers, estuaries and sea channels/harbours. Immersed tubes are often used in conjunction with other ...
Packet Forwarding Control Protocol (PFCP) is a 3GPP protocol used on the Sx/N4 interface between the control plane and the user plane function, specified in TS 29.244. [1] It is one of the main protocols introduced in the 5G Next Generation Mobile Core Network (aka 5GC [ 2 ] ), but also used in the 4G/LTE EPC to implement the Control and User ...
Wilcox Tunnel, which carries Wilcox Boulevard through Missionary Ridge and connects to Shallowford Road. Whiteside Tunnel (Missionary Ridge Railroad Tunnel) carries the Tennessee Valley Railroad Museum trains between East Chattanooga and Grand Junction. Construction of the tunnel was started by the Chattanooga, Harrison, Georgetown and ...
A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics, cable television, and telephone cables are also sometimes carried. One may also be referred to as a services tunnel ...
t. e. In computer networking, Teredo is a Microsoft transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network. Unlike similar protocols such as 6to4, it can perform its function even from behind network address translation (NAT) devices such as ...
IV Sedation. IV sedation will significantly dull—if not completely block—the pain of the procedure. You should expect to spend an additional 15 to 20 minutes in the office while the drugs wear ...
A tunnelling shield is a protective structure used during the excavation of large, human-made tunnels. When excavating through ground that is soft, liquid, or otherwise unstable, there is a potential health and safety hazard to workers and the project itself from falling materials or a cave-in. A tunnelling shield can be used as a temporary ...
