H04TINDEXING SCHEME RELATING TO STANDARDS FOR ELECTRIC COMMUNICATION TECHNIQUE CLASS H04 This scheme constitutes an non-associated internal scheme for indexing exclusively documents issued by standardisation bodies (herein called standards) for electric communication technique (H04).
As standardisation bodies organize their documents in different ways, the present scheme is subdivided into main groups related to a particular CPC range to allow different indexing approaches. Scheme index:
						

						Wireless communication standards
						H04T2001/00
						-
						H04T2001/231
						

						Standards related to data switching
						

						networks in general
						H04T2012/00
						-
						H04T2012/00
						

						Internet standards
						H04T2029/00
						-
						H04T2029/06
H04T2001/00 H04T2001/00Standards for wireless communication networks The indexing codes of this scheme are to be used mainly with classification in CPC subgroups H04W.
In order to keep the structure adopted by the standardisation bodies considered, a matrix type of scheme is used as indicated below: H04T2001/101 - H04T2001/113 codes are used for information relating to the physical aspects, e.g. radio resources, core network resources... H04T2001/201 - H04T2001/231 codes are used for information relating to functional aspects, e.g. physical layer, traffic/transport... For complete indexing it is mandatory to allocate at least one and preferably only one combination of H04T2001/100 and H04T2001/200 codes to a document.
Searching in this scheme is done by combining the above indicated codes, i.e. H04T2001/100 and H04T2001/200 H04T2001/101Radio Resources This subgroup covers radio access network including the radio interface, the interfaces within the radio access network, and the interfaces to the core network(s).

H04T2001/201Physical layer functions This subgroup covers functional aspects relating to the physical transport of information, e.g. modulation, radio propagation, physical channel and frame structuring, synchronisation, as well as antenna characteristics, (e.g. beam steering) and antenna construction details. H04T2001/203TrafficTransport This subgroup covers functional aspects relating to user data transport and control of associated resources on the Physical Layer, e.g. logical channel structuring, Medium Access Control (MAC), Radio Link Control (RLC), power control, multiplexing, switching, transport format conversion and rate adaptation, tunnelling, quality-of-service aspects. H04T2001/205SignallingControl This subgroup covers functional aspects relating to the signalling/control associated to basic call, data, and network services and related signalling trnasport, e.g. RAdio Resource Control (RRC), Base Station System Application Part (BSSAP), Radio Access Network Application Part (RANAP), handoff, call/session control for basic voice and data services, paging, numbering, routing. H04T2001/207Mobility This subgroup covers functional aspects relating to subscriber roaming, e.g. location registration and updating. H04T2001/209Applications This subgroup covers functional aspects relating to applications other than the basic network and call/session services. H04T2001/2091Call related supplementary Services, e.g. Call Forwarding [CF], Cell Barring [CB] H04T2001/2093Intelligent Services H04T2001/2095Location -, Position -, or Presence Services H04T2001/2096Messaging Services H04T2001/2098Device and Node specific Features H04T2001/211Testing and Conformance This subgroup covers functional aspects relating to test and conformity of networks, network nodes or facilities, terminals, and subscriber modules.
