Definition statement

This subclass covers:

Communication networks deploying an infrastructure for mobility management of wireless users connected thereto, e.g. cellular networks, wireless LANs.

Self organizing wireless communication networks, e.g. ad-hoc networks.

Wireless access networks, e.g. Wireless Local Loop.

Said networks are used for selectively establishing one or a plurality of communication links between a desired number of users or between users and network equipments for the purpose of transferring information via these communication links.

Arrangements or techniques for planning, deploying wireless networks.

Arrangements or techniques specially adapted for wireless service provisioning.

Arrangements or techniques specially adapted for wireless network operation.

Special rules of classification

In this subclass, at each hierarchical level, in the absence of an indication to the contrary, classification is made in the first appropriate place.

When classifying in groups H04W 4/00 to H04W 74/00, subject matter relating to system, equipment, interface or protocol, which is considered to represent information of particular interest for search, may also be classified in (the most closely related group of) groups H04W 80/00 to H04W 92/00. Such non-obligatory classification should be given as "additional information".

Glossary of terms

In this subclass, the following terms or expressions are used with the meaning indicated:

Access point

means an equipment providing wireless user access to a backbone network

BSC

Base Station Controller

BTS

Base Transceiver Station

Backbone network

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

means a physical or logical connection selectively established for the purpose of conveying messages or information between users or networks

Connection

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

transports control information used to control the function of the network element ("signalling channel", e.g. paging channel, broadcast channel, pilot channel)

Downlink

means the wireless link from a wireless access point or network towards the user or terminal equipment (see also "uplink")

Home network

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

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

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

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

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

means an entity recognized and authorized as user

Terminal

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

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

means an entity acting as an information source (sender, transmitter, server) or information sink (recipient, receiver, client)

Wireless extension

means equipment using a pre-defined dedicated wireless link

Wireless link

means a communication link established via radio, infra-red, inductive or other electromagnetic radiation

Wireless resource

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

Synonyms and Keywords

In patent documents the following expressions/words "Access point (AP)", "Base Station (BS)", "Node B" and "BTS" are often used as synonyms.
