DIFF Subclass Not Allocatable
H04W

WIRELESS COMMUNICATION NETWORKS (broadcast communication H04H; communication systems using wireless links for non-selective communication, e.g. wireless extensions H04M1/72)

Introduced: January 2009

Description

H04W encompasses wireless communication systems and networks that transmit signals without fixed physical connections between transmitter and receiver. This subclass covers technologies including cellular mobile networks (2G through 5G and beyond), wireless local area networks (WLAN), satellite communications, and short-range wireless protocols such as Bluetooth and Wi-Fi. It includes methods and apparatus for network access, resource allocation, mobility management, and signal transmission across various frequency bands and modulation schemes. Related standards development, system architecture, and interoperability mechanisms between different wireless technologies fall within this scope.

Glossary

access point access points means an equipment providing wireless user access to a backbone network. BSC Base Station Controller BTS Base Transceiver Station backbone network backbone networks designates equipment(s) for connecting one or several wireless access points to a wired or wireless infrastructure in order to allow communication(s) between users' inside or outside the wireless network. Care-of-address designates the termination point of a tunnel toward a mobile node, for datagrams forwarded to the mobile node while it is away from home. communication link communication links means a physical or logical connection selectively established for the purpose of conveying messages or information between users or networks. connection connections means network resource(s) allocated or reserved for an affiliated user. connected state designates the state of a user/terminal having active, i.e. allocated logical traffic/control channel, dormant or suspended, i.e. without allocated logical channels but with maintained service instances. It also incorporates context (PDP context), User Plane, Control Plane operations. control channel control channels transports control information used to control the function of the network element ("signalling channel", e.g. paging channel, broadcast channel, pilot channel). downlink downlinks means the wireless link from a wireless access point or network towards the user or terminal equipment (see also "uplink"). home network home networks designates the network performing functions at a permanent location regardless of the location of the user's access point. The home network is responsible for subscription information management and for specific services not provided by the serving network; dedicated equipment used therefore is designed by HLR (Home Location Register); also for Home Agent, Home Subscriber Server. idle state designates the state of a user/terminal having no active traffic/control channel and no active service instances but being affiliated to the network (see also "Null state"). mobility binding designates the association of a home address with a care-of address, along with the remaining lifetime of that association. mobility management designates techniques or arrangements allowing operation of, or services to be provided to, a user capable of selecting or changing his point of attachment to the network. mobile node mobile nodes designates a host or router that changes its point of attachment from one network or sub-network to another, without changing its home address. multi-call means a plurality of communication links established over one or a plurality of networks for transferring information to one user/terminal. network networks means the physical or logical entities involved in providing communication services to users. null state designates the state of a user/terminal having no active traffic/control channel and no active service instances. originating means a user/terminal acting as a requester for communication towards a wireless access point. partitioning means distributing/committing specific resources to a particular/specific network component. private networks private network designates networks owned and operated by non-public authorities. QoS Quality of Service resource allocation means allocation a resource to a communication. resource distribution means committing a resource to an entity for future allocation thereof for communication. RNC Radio Network Controller scheduling means establishing an order of transmission of communication information based on precedence or priority policies. serving network serving networks designates the part of the network to which the access point providing user's access is connected. The serving network is responsible for path finding and transport of users data; dedicated equipment used therefore is designed by VLR (Visitor Location Register); also for Foreign Agent, Visiting Subscriber Server. SLA Service Level Agreement subscriber subscribers means an entity recognised and authorised as user. terminal terminals means the equipment acting as/or on behalf of a user. terminating means a user/terminal specified as a recipient for communication from within or via a wireless network. traffic channel traffic channels transports communication information (user data) to and from one or several users. uplink means the wireless link from the user or terminal equipment towards a wireless network or access point (see also "Downlink"). user users means an entity acting as an information source (sender, transmitter, server) or information sink (recipient, receiver, client). wireless extension wireless extensions means equipment using a pre-defined dedicated wireless link. wireless link wireless links means a communication link established via radio, infrared, inductive or other electromagnetic radiation. wireless resource wireless resources means a communication link using a specific frequency, time, code or space (or combination thereof). zoned cellular designates an infrastructure deployment involving partitioning geographical areas in a plurality of sub-areas (zones, cells) for the purpose of reusing wireless resources.
