Description
Technical field
The invention belongs to the wireless access technology field, relate in particular to and reduce the method and apparatus that indoor base station disturbs.
Background technology
Along with the flourish and broadband access network of Internet service and the extensive use of wireless network, at a high speed, access network is paid close attention to widely easily.The user also wishes at a high speed more urgently, convenient, use hand-held wireless device to enjoy wireless data service at low cost.Simultaneously, along with 3G (Third Generation) Moblie technology (3G, 3
RdGeneration) deepening continuously of user's continuous growth and Long Term Evolution (LTE, LongTerm Evolved) research, as typical case's representative of private base station, indoor base station (HNB, Home NodeB) is receiving increasing concern.
HNB, be also referred to as indoor access point (AP, Access Point) or pico cell (Femto Cell), be meant miniaturization, family or the office usefulness little base station, may be fully privately owned, also can be under the situation that different priorities, authority are set, the open masses of giving use, its ownership is returned the individual, rather than returns government or operator; Its use object may be user among a small circle, also may be large-scale user.Its essential characteristic is: HNB is bought, oneself is installed by user oneself; The user may be an one family, also may be a collective, such as company or the like, and because HNB is that user oneself buys, oneself installs, so the not very willing HNB with oneself of user uses for others in general, only allows this user oneself to use; HNB generally is to use already present circuit access to mobile network, and a kind of typical access way is digital subscriber line (DSL, the Digital Subscribe Line) access to mobile network by user oneself; Compare with traditional macro base station, the HNB volume is less, and transmitting power is little.
Because HNB has above essential characteristic, introduce HNB and can bring following benefit: concerning the user who uses HNB, can enjoy cheaper communication rate, the while is access to mobile network more easily, enjoys mobile network's service.Concerning operator, can improve the network coverage, reduce network coverage blind spot; Simultaneously also can improve the big hot zones of network capacity, particularly telephone traffic, HNB can share certain network load.
For 3G HNB, HNB possibility integration section or whole radio network controller (RNC, Radio Network Controller) function, be directly connected to core net (CN, Core Network) node, service universal grouping wireless serving GPRS support node (SGSN for example, Service GPRS Support Node) and (MSC of mobile switching centre, Mobile Switching Center), perhaps insert core net by an agency or gateway, these all may be the management nodes of HNB, and operation management maintain (OAM, the OperationAdministration Maintenance) node in territory also can be used as the management node of HNB.
HNB is as a special base station, need circularly the broadcast channel (BCH, BroadcastChannel) so that the user can be resident, further by its paging receiving or make a call.Because it is privately owned that HNB returns, operator carries out network planning possibility hardly to it, and therefore, the phase mutual interference of these BCH will be a great challenge to the successful operation of HNB.With reference to Fig. 1, be the covering relation schematic diagram between HNB sub-district and the macrocell in the prior art, relation between macrocell and the HNB sub-district is specially: HNB1, HNB2, HNB3, HNB4 represent 4 HNB sub-districts respectively, HNB1, HNB2 are under the covering of macrocell A, HNB4 is under macrocell B covers, and HNB3 is under the common covering of macrocell A and macrocell B.Can't pass through under the situation of unified planning, between each HNB sub-district and between each HNB sub-district and each macrocell, will the phase mutual interference.
For the BCH that reduces between the HNB disturbs, the way that prior art adopted generally is: for HNB is provided with different emission modes, comprising: reduce jamming pattern, general mode, adopt different emission modes according to the position of user mobile phone.When the user stays at home, change BCH over to general mode, so that this user can reside among the HNB.After mobile phone leaves, change HNB over to the reduction jamming pattern, adopt low power transmissions or discontinuous emission, with the reduction transmitting power, and then reduction is to the interference of whole system.
In research and practice process to prior art, the inventor finds: when prior art is left at mobile phone, though can reduce interference by reducing transmitting power to whole system, but, when user mobile phone is in and be in holding state, even the user is in holding state always, also need to improve the transmitting power of BCH, broadcast BC H is so that this user is resident always.And generally, stand-by time can be long more a lot of than the air time, and therefore, when user mobile phone was in and be in holding state, bigger HNB broadcast BC H transmitting power was bigger to the interference of whole system.And the end user also is indifferent to resident situation under its holding state, but is concerned about its call scenarios.
In addition, mobile phone is under the holding state, also needs constantly to notify HNB to change general mode over to, this means that the mobile phone under the holding state need be initiated more signaling HNB translative mode, therefore can make mobile phone consume more electric energy, also increase network load simultaneously.

Embodiment
The method, apparatus and system that the embodiment of the invention provides a kind of HNB of reduction to disturb are used to reduce the interference of HNB broadcast BC H to system.
At the system interference problem of bringing between the HNB broadcast channel, the embodiment of the invention generally, HNB closes its wireless transmission unit, leaves home when nearer when subscriber equipment (UE, User Equipment), triggers the wireless transmission unit switch by business.When UE has business, and in the coverage threshold value of HNB sub-district the time, just open the wireless transmission unit of HNB.With reference to Fig. 2, for reducing the method flow diagram that HNB disturbs in the embodiment of the invention, concrete steps are as follows:
201, when UE has professional the connection, obtain the UE current location information;
Generally, HNB closes its wireless transmission unit, but monitors the order of network side or UE transmission.When the user was in, UE resided in the macrocell that operator provides.
UE has professional the connection, comprises that professional trigger process and business carry out in the process, and for example, this UE makes a call or session, and when receipt of call or session, perhaps call out with conversation procedure in.
The business of being carried out both can be speech business, for example, made a phone call; Also can be data service, for example download or Video chat or the like.
202, when the UE current location information is in the HNB coverage area threshold of the UE correspondence of preserving in advance, indication HNB open wireless transmitting element;
Network side or UE store the HNB location dependent information of this UE correspondence in advance, for example, the public mobile communication base station cell of HNB correspondence sign (ID, Identification).The HNB sub-district is generally in the coverage area threshold of some or a plurality of public mobile communication base station cells, therefore, network side or UE can keep the public mobile communication base station cell ID that overlapping public mobile communication base station cell is arranged with this HNB cell coverage area, if the public mobile communication base station cell ID that the HNB that public mobile communication base station cell ID and the network side or the UE of the public mobile communication base station cell at the current place of UE preserve in advance is corresponding has when identical, indication HNB opens its wireless transmission unit.
The wireless transmission unit specifically can be a wireless transmitter.
The coverage area information of the public mobile communication base station cell of Bao Cuning comprises the standard coverage and the artificial allowance value that is provided with of described public mobile communication base station in advance.
203, the UE that will reside in the public mobile communication base station cell switches to the HNB sub-district of UE correspondence.
From this embodiment as can be seen, under normal conditions, the wireless transmission unit of HNB is closed, UE resides in the public mobile communication base station cell, only there be professional the connection the user, and when the UE current position information covers in the threshold value in the HNB zone of the UE correspondence of preserving in advance, promptly be in or be in when neighbouring as the user, just indicate HNB open wireless transmitting element, and the UE that will reside in the public mobile communication base station cell switches in the HNB sub-district of UE correspondence, therefore, in most of the cases, HNB is a broadcast BC H-channel not, therefore, can not cause interference, thereby can reduce the interference of HNB system to other HNB or public mobile communication base station cell.
Simultaneously, because under normal conditions, the wireless transmission unit of HNB is closed, and therefore, can reduce the power consumption of HNB, and can reduce radiation, guarantees that HNB is the indoor wireless equipment of a health environment-friendly.
Below by a preferred embodiment concrete application under the scene that UE makes a call is described, with reference to Fig. 3, be to reduce method preferred embodiment one flow chart that HNB disturbs in the embodiment of the invention, below be described in detail by concrete steps:
300, UE resides in the macrocell, and HNB wireless transmission unit is closed;
Generally, HNB closes its wireless transmission unit, and when the user was in, UE resided in the macrocell that operator provides.
301, UE is to wireless access network/core net (RAN/CN, Radio Access Network/CoreNetwork) request of making a call;
302, RAN/CN judges the current position of UE;
RAN/CN can judge according to the current place of UE macrocell ID or positional information.
RAN/CN can be identical by judging whether the corresponding macrocell sign of HNB that the current place of UE macrocell ID and RAN/CN preserve in advance has, if identical, illustrates that then UE may be in.Generally, HNB can be in the overlay area of one or more macrocells, RAN/CN preserves the macrocell sign that these overlapping macrocells are arranged with the overlay area of HNB in advance, when UE makes a call request, RAN/CN can obtain the macrocell sign of the current place of UE macrocell, if current UE place macrocell ID and the macrocell ID that preserves in advance have when identical, illustrate that UE may be in or be near.The overlay area that can learn the pairing macrocell of this macrocell ID according to the macrocell ID of preservation in advance, described overlay area also can add the allowance value of artificial setting.
RAN/CN also can judge the current position of UE by positioning function, for example, can pass through Cell ID+TA, specifically be meant: RAN/CN is according to the macrocell sign of the current place of UE macrocell, can obtain the accurate position of this macrocell sign respective base station, the distance of UE and base station self can be measured according to time deviation,, the UE current location can be drawn by the mode of solving equation group according to a plurality of base station distance.RAN/CN compares current UE position and the exact position of the HNB that preserves in advance or the overlay area of HNB, judges.
Positioning function also can be located by GPS and be realized, specifically: have corresponding global positioning system (GPS on the UE, Global Position System) positioning unit, the GPS positioning unit can be reported to RAN/CN with the UE current location, RAN/CN compares current UE position and the exact position of the HNB that preserves in advance or the overlay area of HNB, judges.
303, when UE was in the coverage area threshold of HNB sub-district, RAN/CN sent signaling to HNB, indication HNB open wireless transmitting element;
304, HNB open wireless transmitting element;
Generally, the wireless transmission unit of HNB is closed, and issues its order but monitor network side always, when receiving the instruction of the open wireless transmitting element that RAN/CN sends, the wireless transmission unit is opened.
305, between UE and the RAN/CN through consultation, set up to call out connect;
306, UE converses by the calling connection of setting up;
307, HNB broadcasts its BCH;
Behind the HNB open wireless transmitting element, the BCH that goes on the air is so that UE can reside in the HNB sub-district.
308, RAN/CN sends measurement control order to UE, and indication UE measures the channel quality of HNB;
309, UE is reported to RAN/CN with the channel quality information of the HNB that measures;
310, after RAN/CN receives the channel quality measurement report to HNB of UE, judge whether the channel quality that measures can reach default cqi, if, then initiate handoff procedure, UE is switched in the HNB sub-district;
If it is relatively poor that UE can not measure the channel quality of HNB or HNB, expression UE only is in neighbouring and is not in, and HNB can't satisfy the conversation requirement of UE, and then RAN/CN does not initiate handoff procedure, UE will measure HNB information always, and report according to the order measurement of RAN/CN side.
Because the user also is indifferent to UE and resides in which sub-district, but be concerned about call scenarios, therefore when the channel quality of measurement HNB can't satisfy the conversation demand of UE, do not switch, can avoid frequent switching, and can guarantee that the user has speech quality preferably.
311, UE converses by the HNB sub-district;
312, UE end of conversation;
313, RAN/CN indication HNB closes its wireless transmission unit;
314, HNB closes its wireless transmission unit;
315, UE resides in the macrocell.
In step 312～step 315, the end of conversation of UE, HNB are closed the wireless transmission unit, and UE resides in the macrocell of operator.
From this embodiment as can be seen, under normal conditions, the wireless transmission unit of HNB is closed, even UE is in the overlay area of HNB, if there is not business, also be to reside in the macrocell, have only when the overlay area of UE at HNB, and in the UE process that makes a call and converse, network side is by judging the channel quality of HNB, when it can reach default cqi, just indicate HNB open wireless transmitting element, and the UE that will reside in the macrocell switches in the HNB sub-district.Because the wireless transmission unit of HNB is generally closed, therefore, can not produce interference, thereby can reduce interference whole system to other HNB or macrocell.
And, only at UE in the overlay area of HNB and business are carried out, HNB just opens its wireless transmission unit, can reduce the power consumption of HNB, also can reduce the radiation of HNB simultaneously, guarantees that HNB is the indoor wireless equipment of a health environment-friendly.
Judge the current position of UE by RAN/CN, do not need UE is carried out particular processing that existing UE also can accept the HNB service, does not need to define new UE.And when in the coverage area threshold of UE at HNB, UE does not need constantly to send signaling to HNB, thereby can save the power consumption of UE under holding state, has reduced network load simultaneously yet.
In the above-described embodiments, if UE is because of moving or switching, RAN/CN be sure of that it stays out, for example apart from too far away or enter new public mobile communication base station cell, then RAN/CN will resend the measurement directive command, indication UE cancellation to reduce the power consumption of UE, reduces network load to the measurement of HNB.
UE in the called process, disturbs the handoff procedure that carries out basic identical for reducing HNB in the overlay area of HNB the time, repeats no more.
Be understandable that,, can open the wireless transmission unit of HNB in advance, even insert directly redirected this UE in back to sub-district, HNB place at UE if RAN/CN shifts to an earlier date clear and definite UE current location information.For example, UE can report the current UE positional information to RAN/CN by the GPS positioning function.
The process that above-mentioned preferred embodiment makes a call by UE illustrates that the embodiment of the invention reduces the method that HNB disturbs, in actual applications, the operation of HNB open wireless transmitting element also can be carried out in communication process, for example: when UE when the public mobile communication base station cell of leaving home far away makes a call, HNB/CN can not start HNB wireless transmission unit, but when UE keeps conversation and moves to the sub-district of leaving home nearer, HNB/CN can send the instruction of open wireless transmitting element according to the current position information of UE.
With in the UE communication process, RAN/CN can indicate HNB open wireless transmitting element, and is corresponding, and RAN/CN indication HNB closes the instruction of wireless transmission unit and also can send in communication process.For example, when UE keeps conversation, and when moving to outside the overlay area of HNB sub-district, RAN/CN can indicate HNB to close its wireless transmission unit.
The embodiment of the invention also can be applied to the situation that HNB and RAN are different wireless access networks, for example, that HNB adopts is Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division MultipleAccess) technology, be in the WCDMA system, and RAN is a gsm system, at this moment, the UE that is in can insert in GSM, RAN starts HNB, measure and handoff procedure by wireless access technology mutual (Inter-RAT, Inter-Radio Access Technology) then, this session or voice call are switched among the HNB of WCDMA.
Network side is except being the RAN/CN, can also be other Operation ﹠ Maintenance System such as OMA system.
Be understandable that, when the wireless transmission unit that indicates whether to open HNB by network side the time, under normal conditions, the radio receiving unit of HNB also can be closed, network side can notify HNB whether to start radio receiving unit and wireless transmission unit by cable network, further to reduce the power consumption of HNB.The wireless transmission unit specifically can be a wireless transmitter, and radio receiving unit specifically can be a wireless receiver.
In the above-described embodiments, UE generally resides in the macrocell of operator's operation and management, and the coverage of macrocell is: 2～20km.In fact, different according to concrete environment and coverage requirement, some common moving base station cells that also have other of operator's operation, for example, Microcell (Micro-cell) and skin sub-district (Pico-cell), wherein, the coverage of Microcell is 0.4～2km, the coverage of skin sub-district also has multidimensional sub-district etc. in addition less than 400m.
In actual applications, also can by UE judge self whether have professional connect and whether be near, and then the UE that carries out the public mobile communication base station cell that will generally reside in operator's operation switches in the HNB sub-district.Below describe by a preferred embodiment:
With reference to Fig. 4, be to reduce in the embodiment of the invention method preferred embodiment two flow charts that HNB disturbs, below be elaborated by concrete steps:
400, UE resides in the macrocell, and HNB wireless transmission unit is closed;
