Description
Technical field
The present invention relates to aerogram, specifically, 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 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, they and radio access network carry out voice and/or data communication.Perhaps, wireless user equipment units can be stationary wireless device, such 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 residential quarters, and wherein each residential quarter provides service by the base station.The residential quarter is the geographic area that the radio covering is provided by the wireless base station unit at base station site place.Each residential quarter identifies by the unique identifier of broadcasting as the part of system information in the residential quarter.The base station communicates by the user equipment unit (UE) in air interface and the base station scope.In radio access network, some base stations usually (for example by land line or microwave) are 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 connect.Radio network controller is typically connected to one or more core networks.Core network has two service-domains, and wherein RNC has the interface with these two territories.
An example of radio access network is Universal Mobile Telecommunications System (UMTS) terrestrial radio Access Network (UTRAN).UMTS is third generation system, is that the radio access technologies that is called global system for mobile communications (GSM) take Europe exploitation is for basic 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 simultaneously communication 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) code.These high speeds PN code is used for modulating the signal from base station and user equipment unit (UE) emission.Using the transmitter station of different PN codes (or PN code of upper skew of time) to produce can be at the independent demodulated signal of receiving station.High speed PN modulation also allows receiving station to receive signal by producing from single cell site in conjunction with the some different propagation paths that transmit easily.Therefore, in CDMA, when connecting switching from a residential quarter to another residential quarter, 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 residential quarter 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 concerned interfaces.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 processed 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 emission, the up link (UL) that feels the base station by this class resource of RNC management.
Those skilled in the art will recognize that for certain RAN-UE to connect that RNC can have the effect of Serving RNC (SRNC) or have the effect of Drift Radio Network Controller (DRNC).If RNC is Serving RNC (SRNC), then this RNC is responsible for and being connected of user equipment unit (UE), and for example, it controls the connection in the radio access network (RAN) fully.Serving RNC (SRNC) is connected to core network.On the other hand, if RNC is Drift Radio Network Controller (DRNC), then it supports Serving RNC (SRNC) by providing with the required radio resource (in the residential quarter of Drift Radio Network Controller (DRNC) control) that is connected of user equipment unit (UE).Comprise drift radio network controller (DRNC) and be called in this article DRNC subsystem or DRNS by the system of drift radio network controller (DRNC) by the base station of Iub interface control.It is control RNC (CRNC) by the connected base station of Iub interface that RNC is said to be.This CRNC effect is not that UE is specific.CRNC wherein also is responsible for processing the provided for radio resources management by the residential quarter in the connected base station of Iub interface.
The possibility of using small radio base station (" RBS ") to come to provide as the user of limited quantity family or zonule WCDMA covering is being investigated by some operators, and wherein small radio base station (" RBS ") is called again " femto RBS " and/or " RBS of family " and/or " slightly RBS " and/or " little RBS " 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 access (such as xDSL, Cable etc.) that the RBS of family is connected to RNC.Another alternative is to use WiMAX access (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 ".
Some nano-micro-radio base stations nodes comprise grand receiver, are used for receiving the one or more scanning cell informations (for example system information) that receive Cell Broadcast CB to radio access network.Grand receiver also can be used for carrying out the measurement that can receive the residential quarter, for example according to the dissimilar signal strength signal intensity of current mechanism.For example, nano-micro-radio base stations can be equipped with the WCDMA receiver, and make nano-micro-radio base stations can preempt the WCDMA residential quarter, and read the pertinent system information of those residential quarters, and also to these residential quarter executive signal ionization meters.Consist of with signal strength measurement or form " detection coverage information " can receiving the system information that receives in the residential quarter.In some cases, detect coverage information and only comprise the system information (for example not having described measurement) that receives.
Nano-micro-radio base stations to user equipment unit (UE) to use WCDMA with conventional (for example grand) mode that the WCDMA radio base station is identical.Studies show that, use in the transmission that may best situation is nano-micro-radio base stations between the user equipment unit of nano-micro-radio base stations and nano-micro-radio base stations service with grand WCDMA and cover the different frequency of used frequency (frequencies that the frequency of the grand radio base station when for example, nano-micro-radio base stations is relating to user equipment unit by the nano-micro-radio base stations service in use and the overlapping macrocell is different).Use by this way different frequencies between two radio nets (grand and femto), to cause least interference, and minimum " white point " is provided.White point is can not provide the place of covering owing to the interference from other network has network.
The staff of operator, as having or safeguarding that the office worker of the company of operator of the grand RBS node of radio access network (RAN) and RNC node installs grand RBS node usually.As a part of installing, the IP addressing information of the RNC that is connected to grand RNC (dns name claims, fully qualified domain name FQDN or IP address) the grand RBS of human configuration.In general, common WCDMA base station (grand RBS) can use IP-based transmission to be connected to RNC.Need quite a large amount of radio net plannings to dispose radio net, and wherein also comprise the frequency that selection will be used.
On the contrary, femto RBS installs by the terminal use rather than by 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 the operator.This user instruction reorientate requirement: no matter nano-micro-radio base stations is installed or where is arranged on, and it all should be connected to correct RNC." correct RNC " or " preferred RNC " or " suitable RNC " are at the identical RNC that aspect this is the overlapping macrocell of control radio access network (RAN).It is important being connected to correct RNC, because for example it has also improved the roaming between femto RBS and the grand RBS residential quarter and has switched the formation of required neighbor cell list.In addition, it has minimized the network signal between the controller node.
