Description
Technical field
The present invention relates to wireless telecommunication, particularly relate to the operation of " femto " or " slightly " radio base station of radio access network.
Background technology
In typical cellular radio system, wireless user equipment units (UE) communicates through radio access network (RAN) and one or more core networks.User equipment unit (UE) can be a travelling carriage, mobile phone (" honeycomb " phone) and have the laptop computer of portable terminal for example, thereby can be for example portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they and radio access network carry out voice and/or data communication.Perhaps, wireless user equipment units can be a stationary wireless device, for example as fixed cellular device/terminal of the part of wireless local loop etc.
Radio access network (RAN) covers the geographic area that is divided into some sub-districts, and wherein each sub-district provides service by the base station.The sub-district is the geographic area that the radio covering is provided by the wireless base station unit at base station site place.Each sub-district identifies by the unique identity as system information broadcast in the sub-district.The base station communicates by the user equipment unit (UE) in air interface and the base station scope.In radio access network, several base stations (for example by land line or microwave) usually is connected to radio network controller (RNC).Radio network controller is also referred to as base station controller (BSC) sometimes, the comings and goings of a plurality of base stations that its monitoring and coordination are connected.Radio network controller is typically connected to one or more core networks.Core network has two service-domains, and wherein RNC has the interface to these two territories.
An example of radio access network is Universal Mobile Telecommunications System (UMTS) terrestrial radio Access Network (UTRAN).UMTS is a third generation system, is based on the radio access technologies that is called global system for mobile communications (GSM) of Europe exploitation in some aspects.UTRAN is the radio access network that Wideband Code Division Multiple Access (WCDMA) (WCDMA) is provided to user equipment unit (UE) in essence.Third generation partner program (3GPP) has set about further developing UTRAN and based on the radio access network technology of GSM.
Those skilled in the art will recognize that in the WCDMA technology common band allows communication simultaneously between user equipment unit (UE) and a plurality of base station.In receiving station by distinguishing the signal that takies common band based on the spectrum CDMA waveform characteristic of using high speed pseudo noise (PN) sign indicating number.These high speeds PN sign indicating number is used for modulating the signal from base station and user equipment unit (UE) emission.Using the transmitter station of different PN sign indicating numbers (or time go up PN sign indicating number of skew) to produce can be in receiving station separately by the signal of demodulation.High speed PN modulation also allows receiving station easily by coming to produce received signal from single cell site in conjunction with the some different propagation paths that transmit.Therefore, in CDMA, connecting to another sub-district from a sub-district when switching, user equipment unit (UE) does not need inversion frequency.Like this, cell of origin continue as connect service is provided in, Target cell can be supported and being connected of user equipment unit (UE).Because user equipment unit (UE) communicates by at least one sub-district in handoff procedure all the time, therefore do not call out and interrupt.Therefore be called " soft handover ".Compare with direct-cut operation, soft handover is " carrying out before the interruption " conversion operations.
The telecommunication system that comprises other type of radio access network comprises: global system for mobile communications (GSM); Advanced mobile phone service (AMPS) system; Arrowband AMPS system (NAMPS); Total access communication system (TACS); Personal digital cellular (PDC) system; U.S.'s digital cellular (USDC) system; And the code division multiple access of describing among the EIA/TIA IS-95 (CDMA) system.
In UTRAN, there are several interfaces of being paid close attention to.Interface between radio network controller (RNC) and the core network is called " Iu " interface.Interface between radio network controller (RNC) and base station (BS) thereof is called " Iub " interface.Interface between user equipment unit (UE) and the base station is called " air interface " or " radio interface " or " Uu interface ".In some cases, connect and to relate to source and Serving RNC (SRNC) and target or Drift Radio Network Controller (DRNC), SRNC control connection wherein, but the one or more various branch that connects is handled by DRNC.Transmission link can be used for the transmission that control and data signal between source RNC and drift or the Target RNC between RNC, and can be direct link or logical links.The interface of (for example between Serving RNC (SRNC) and the Drift Radio Network Controller (DRNC)) is called " Iur " interface between the radio network controller.
Radio network controller (RNC) control UTRAN.In realizing its control action, the resource of RNC management UTRAN.The hardware that disturbs and be positioned at the base station comprising down link (DL) power of base station, the up link (UL) that feels the base station by this class resource of RNC management.
Some operators are investigating and are using small radio base station (" RBS ") to come to provide as the user of limited quantity the possibility of family or zonule WCDMA covering, and wherein small radio base station (" RBS ") is called " femto RBS " and/or " RBS of family " and/or " RBS slightly " and/or " little RBS " again in some contexts.According to this investigation, little RBS will provide conventional WCDMA to cover for terminal use's (for example being user equipment unit (UE)), and will use certain IP-based transmission to be connected to RNC.The overlay area that provides like this is called " Femto cell " (smaller with the indication overlay area).Other term of Femto cell comprises " picocell " or " Microcell ", and it and macrocell grand or standard radio base station (RBS) covering form contrast.
An alternative of IP-based transmission is to use fixed broadband to insert (for example xDSL, Cable etc.) RBS of family is connected to RNC.Another alternative is to use WiMAX to insert (for example HSDPA and enhanced uplink or WiMAX).Fig. 5 illustrates in greater detail two kinds of different backhaul alternatives.First alternative is labeled as " xDSL backhaul ", and second alternative is labeled as " WiMAX backhaul ".
In general, by the staff of operator, as having or safeguarding that the office worker of company of operator of the RNC node of grand RBS node and radio access network (RAN) installs and dispose common WCDMA base station (grand RBS).As a part of installing, use operating parameter, as the grand RBS of neighbor cell list information manual configuration.
On the contrary, femto RBS installs by the terminal use rather than by Virtual network operator usually.The terminal use can also move to another place from a place geographically with femto RBS, can or be ready to control reorientating of femto RBS and need not operator.This user guided reorientate require to handle operating parameter automatically, as neighbor cell list information.
Neighbor cell list is the set of cells that should measure the user equipment unit of idle pulley to it.Neighbor cell list (being called " Neighboring Cell List " again) is generally comprised within from radio base station and provides the broadcasting of idle mode subscriber device unit of service to radio base station.Send the Neighboring Cell List of monitored set form to the user equipment unit (dedicated signaling that passes through to user equipment unit connects) of activity pattern or connected mode.Monitored set is listed and will be used for measuring the tabulation of the neighbor cell that may switch to from this sub-district that Control Node (as the radio controller node) ordered by user equipment unit.
In other words, the information that base station broadcast and the user equipment unit (UE) of idle pulley should be relevant to its neighbor cell of measuring is so that allow UE determine to preempt which sub-district.Under the situation of active session, the tabulation of the sub-district of monitored set connects transmission (promptly by dedicated signaling, be not broadcasted in this case) to this UE, and guide UE which sub-district is carried out measurement report and the switching to which sub-district that RNC orders may be taken place.
Term as used herein " neighbor cell list " and " Neighboring Cell List " are used for the broadcast idle mode neighbor cell list and are used for activation/connected mode neighbor cell list (being monitored set).
Create the tabulation of this class sub-district, need a large amount of operations and management (O﹠amp; M) work and back-up system.Tabulation also should be loaded into network controller (for example on the RNC node) and be associated with correct base station.This increases the risk of manual errors again.
Because the processing of Neighboring Cell List needs extensive work, under the situation of slight (femto) base station, can increase required work considerably, particularly because femto base station can move to new position by the terminal use, as mentioned above.Traditionally, insert the automated manner that does not have automatic structure neighbor cell list in alternative or some variation at fixed broadband in the WiMAX alternative.
Therefore, target required and that this paper provided is the new auto-mechanism that makes up the Neighboring Cell List of the nano-micro-radio base stations that IP connects.
