name: UDP
full_form: User Datagram Protocol
context: Transporting the CDRs from the CDFs to the CGF over the Ga reference point may facilitate charging. The Path Protocol may be UDP (compliant with STD 0006 [404]) or TCP (compliant with STD 0007 [405]) over IP. - UDP as the Path Protocol Ports for signalling the request messages: - The UDP Destination Port may be the server port number 3386 which has been reserved for GTPâ. Alternatively another port can be used, which has been configured by OAM&P, except Port Number 2123 which is used by GTPv2-C. - The UDP Source Port is a locally allocated port number at the sending network element. NOTE: UDP Source Port number should be different than UDP Source Port number allocated to GTPv2 (see TS 29.274 [201]). Ports for signalling the response messages: - The UDP Destination Port value shall be the value of the Source Port of the corresponding request message. - The UDP Source Port shall be the value from the Destination Port of the corresponding request message. - TCP as Path Protocol The TCP
description: User Datagram Protocol (UDP) is a communication protocol used for transporting data in telecommunications networks. It's particularly relevant in charging and billing processes over the Ga reference point.
explanation: The text states that UDP is used for 'transporting data' and specifically mentions its application in 'charging and billing processes', which are typical functions of a communication protocol.
