Description
Technical field
The present invention relates to the method for a kind of network node and subscriber equipment (UE), this method is used for the UE dedicated cell gravity treatment under the public network idle pulley.Public network comprises that at least one covers the public base station of common cell, and UE also can communicate with dedicated network, and dedicated network comprises that at least one covers the private base station of dedicated cell, and UE inserts authority in dedicated network be limited.
The invention still further relates to a kind of UE, network node and system that is used for carrying out the reselection operation of dedicated cell at the UE that public network is in idle pulley.Public network comprises a public base station that covers a common cell at least.UE also can communicate with dedicated network, and dedicated network comprises a private base station that covers a dedicated cell at least, and UE inserts authority in dedicated network be limited.
The present invention also relates to a kind of computer program of carrying out the inventive method, and the computer program of carrying out the inventive method.
Background technology
The present invention relates to wireless communication system, particularly comprise the wireless communication system of private base station, this private base station is such as being the small-sized household equipment that small-scale UE group is had the restriction of inserting.
Along with (the 3rd Generation PartnershipProgram of third generation partner program in the wireless communication standard, evolved universal terrestrial radio access network (Enhanced UTRAN 3GPP), E-UTRAN), be also referred to as Long Term Evolution (Long Term Evolution, demand to special-purpose small-sized household equipment has appearred in development LTE).
Private base station should comprise that at least function, the especially private base station of wireless base station should provide the function of wireless base station for very little sub-district, and such sub-district is called millimicro (Femto) sub-district or slight (pico) sub-district.In this article, the notion of private base station should comprise the equipment of various micro radios base station, as indoor office equipment, can also comprise covering conventional wireless base station equipment in a big way., as what introduce above, the UE in the system is limited to the access authority of these private radio base station equipments.
In addition, although this paper is example with 3GPP and E-UTRAN, the present invention also can be applied in the known radio access technologies of any those skilled in the art.In this article, any network node of " base station " general reference overlay network sub-district, as the wireless base station, Node-B Node B (NB), enode bs (eNB) etc. are other network node similarly.In addition, " UE " here make a general reference can with any mobile entity of this class base station communication, as travelling carriage (MS), entities such as UE.Herein " dedicated cell gravity treatment " is used for UE dedicated cell carried out the sub-district gravity treatment.
Fig. 1 is the schematic diagram of a 3G E-UTRAN example.The framework of E-UTRAN is simpler relatively than the framework of UTRAN.As shown in Figure 1, (Radio Network Controller RNC), and has only defined two kinds of node types, i.e. eNB and IAD (MME/SAE) to have removed the center radio network controller that is used for controlling a plurality of NB in E-UTRAN.Wherein eNB belongs to the E-UTRAN network, and (Evolved Packet Core, EPC) network adopt X2 interface between the eNBs, the interface between eNB and the MMS/SAE gateway adopts the S1 interface and the MME/SAE gateway belongs to evolution block core.Universal mobile telecommunications system (Universal Mobile Telephony System, UMTS) adopted similar network architecture, especially (High Speed Packet Access, HSPA) in the system evolved, RNC and NB merge into same node in the high-speed packet access.
When UE roamed with idle pulley in network, it was by selecting the most suitable resident sub-district to the measurement of determining the sub-district.
The sub-district of selecting as UE belongs to another one tracking area (Tracking Area, TA), rather than during itself at present resident tracking area, UE is to its core network (Core Network, CN) send a TA and upgrade (TA Update, TAU) solicited message is used for notifying this UE of CN its area of coverage of conversion.
(Closed User Groups, private base station notion CUG) has brought new direction for the access of cellular network to closed user group.That herein, " limited access authority " refers to is exactly these CUG.In same zone, a large amount of sub-districts that may exist private base station to cover, this zone is also covered by the public base station in the normal public cellular network simultaneously.Yet UE only has the authority of one of access or some these private base stations.Because required information depends on concrete UE, and is not to be applicable to all UE, so the solution of broadcasting neighbor cell list has not just had attraction in the UTRAN sub-district.By broadcasting the needed information of a large amount of UE, realize inserting a private base station, will produce a large amount of system signaling expenses, because for transmission UE information specific, broadcasting is a kind of very inaccurate method.
Global system for mobile communications (Global Systemfor Mobile communication, GSM) in, (Cordless Telephony System CTS) has proposed the notion of small-sized household equipment, as described in document [5] to radio telephone system.(the list of references tabulation is positioned at the last of this specification.) here, these mobile management of wanting to insert the travelling carriage of CTS sub-district are controlled by UE, and preferentially select GSM or preferentially select the CTS system, can manual or configuration automatically under six kinds of different modes.
A kind of CUG that solves of document [3] proposition limits the method that inserts, and is the tabulation of formulating the TAs that allows the UE access, and makes the information of private base station transmission about its access state, promptly is configured to public access or limited access.A defective of this solution is may have a large amount of private base stations in the system, and therefore causes system to exhaust its identifier.
Document [2] has been introduced the problem of identifier.Tracking Area Code (Tracking Area Code, TAC) and the soft difference between the cell identifier make the bit number of TAC depend on the number of cells that TA comprises.
Yet above the background technology solution of Jie Shaoing has following problem: in order to make UE only insert the private base station that it has authority, the idle pulley that needs to carry out a large amount of proprietary base stations detects and search and other signalings.
In addition, in background technology, (Neighbor Cell Lists, NCLs) broadcasting needs the occupied signaling expense to neighbor cell list in the minizone.Because comprise a large amount of dedicated cells in the network, this mode will be produced a large amount of signaling spendings.The neighbor cell list of all these dedicated cell information that comprise may be very huge, will produce a large amount of signaling consumptions.Different UE has the authority that inserts different private base stations, and it is useful that UE is had only its information that can insert the sub-district, so the most information in the signaling is useless for most of UE.
Summary of the invention
The objective of the invention is to solve the problem that relates in the above-mentioned dedicated cell gravity treatment.
The purpose of this invention is to provide a kind of dedicated cell reselecting method, for prior art dedicated cell reselecting method, need less measurement, search and signaling.

Embodiment
In comprising the system of private base station, need one can effectively handle effective flow process that UE is linked into private base station, particularly to the processing of signaling in measurement, search and the network of private base station.
Document [1] shows the begun one's study demand of special-purpose base station among the LTE of some researchers, and is concrete, listed in the document [1] requirement about idle mode mobility below.
If I does not allow UE to use (use) to cover the private base station of certain specific cell, then should avoid the UE of LTE idle condition to insert this specific sub-district.
If II does not allow UE to insert the private base station that (access) covers certain specific cell, then should avoid the UE of LTE idle condition resident in this specific sub-district.
If III does not allow UE to insert (access) certain specific private base station, should reduce the measurement number of times of the UE of LTE idle condition at this private base station.
If IV does not allow UE to insert (access) certain specific private base station, should reduce that (Radio Access Technology is in the measurement number of times of the UE of arbitrary cells gravity treatment state at this private base station in RAT) in another wireless access technology.
V allows the reselecting parameters of the UE of access sub-district to be provided with, and UE can distinguish the order of priority of private base station like this.
To the analysis showed that of document [5], wherein do not propose when UE is not positioned at the adjacent domain of CTS, to avoid the method for UE search CTS sub-district.Therefore the solution of document proposition does not satisfy the requirement of above-mentioned IV.
In addition, document [2] does not propose any method and controls the measurement that how to reduce private base station.Therefore the document proposes the requirement that solution does not satisfy above-mentioned III-IV.
The UE here can communicate with two kinds of radio communications systems, comprises private base station in a kind of system, comprises public base station in the another kind of system.Wherein public base station is meant without any inserting and limits, the ordinary base station that coverage rate is very wide, and the zone of its covering is such as being: the big regional macrocell in the common common communication system.In the overlay area of so big regional macrocell, may comprise up to a hundred dedicated cells.Broadcast channel overload for fear of covering macrocell further requires proximity detection can not only rely on the broadcasting neighbor cell list.And the broadcasting neighbor cell list is the conventional method of control sub-district gravity treatment in the background technology.
According to the present invention, comprise the use of proximity parameter in the UE cell re-selection procedure of idle pulley.With regard to the gravity treatment of sub-district, UE should be based on searching for dedicated cell with the adjacency of its private base station that can insert.So according to the present invention, to the search of private base station based on having the adjacency of the private base station that inserts authority with UE.In addition, according to UE with and with the information of the relation of private base station, can judge whether UE is close to this private base station.In other words, this judgement is based on the information relevant with the particular UE of being discussed.Therefore, need a lot of signalings since broadcast big NCL, the signaling consumption that does not need to increase NCL broadcasting in the sub-district just can significantly reduce the expense of sub-district.
Different embodiment according to the subject invention, the adjacency parameter that is used for the dedicated cell gravity treatment can be detected or be detected by other method by UE, private base station, public base station.If UE itself does not detect the adjacency parameter, the equipment that then detects this parameter needs this adjacency parameter is indicated to UE.
According to the present invention, adjacency indication is a kind of like this indication, and promptly for resident or carry out the enable mode session, or both have concurrently, specific private base station is had the UE that inserts authority near this certain base station or entered the coverage of this certain base station.
According to the present invention, only when contiguous this UE of UE has the private base station that inserts authority, this private base station is carried out sub-district gravity treatment search.
Have the private base station that inserts authority unless the advantage of doing like this is the UE that is in idle pulley near it, otherwise can on private base station, not waste sub-district gravity treatment search, measurement and other signaling.Fundamentally reduced the signaling of using in search, measurement and other system in this way.So idle mode cell gravity treatment flow process of the present invention has satisfied the requirement of above-mentioned I-V.
May there be a lot of different proximity detection mechanism in the system.As proximity detection can be that graduate, elementary adjacency mechanism can trigger the finer mechanism of using.Such as, can after identification is such as a certain band of position, tracing area or Routing Area, use finer mechanism.
In one embodiment of the invention, proximity detection is carried out by UE, and promptly UE detects the adjacency that has the private base station that inserts authority with it.The relevant information of detection or be close sub-district adjacent with identification with specific dedicated cell based on storage.Therefore, UE can store the cell information and the cell relation information of proprietary sub-district and its peripheral cell.These information can be stored in subscriber identification module, and (SubscriberIdentity Module is SIM) in other memory device of card or UE.Resident or when leaving dedicated cell as UE at dedicated cell, can read information from the adjacent cell that is in enable mode and set up these information.
On the other hand, based on operation and maintenance (Operations and Maintenance, O﹠amp; M) network schemer, network can be UE this information are provided.As network O﹠amp; When the M pattern changes, or customized information is when changing, can in UE, upgrade: for example pass through to use the short message (often not using) of " SIM card tool box (SIM-toolkit) ", the short message when short message of customization (based on mobility) or tracing section updating (when UE enters the TA with dedicated cell) this information.
Fig. 2 is an example of the content that cell relation information comprised.As shown in Figure 2, the relevant information of private base station of UE storage and its access of permission is as the PBS-3 among Fig. 2, with adjacent common cell, information that macrocell mNB-1 is relevant with mNB-2, and UE do not insert other private base station relevant information of authority, as PB2 to PB5.
Cell relation information also can be stored in the network node, in public base station or private base station.
No matter where cell relation information is stored in, can comprise with at least one UE and have the relevant information of private base station that inserts authority, the relevant information of adjacent private base station with at least one, the relevant information of adjacent public base station with at least one, with logic district value (LCV), carrier frequency, sub-district ID, or the relevant information of public public land mobile net network (PLMN).
When UE roams, keep following the tracks of adjacent sub-district in network.When UE recognizes one or several when being defined in sub-district in its cell relations mapping table, UE begins to search for it and has the private base station that inserts authority.In other words, have in the sub-district of the private base station that inserts authority when UE finds self to be in any one contiguous its, UE can reach a conclusion by the cell relation information of analyzing self: UE is near it has the private base station that inserts authority.At this moment UE begins this private base station is carried out sub-district gravity treatment search.
Detect adjacency based on the information relevant with sub-district and cell relations, its benefit is in the process of normal running, and UE or network can be collected this information easily, thereby make proximity detection more effective.
On the other hand, UE can utilize location technology to detect the adjacency that has the private base station that inserts authority with it, as global positioning system (Global Position System, GPS) position technique, or Galileo location technology.The advantage of doing like this is to be very easy to obtain accurate geographical position.
Can also be that UE utilizes other UE application technologies to detect adjacency.If UE can move other application technologies, as WLAN (wireless local area network) (Wireless Local Area Network, WLAN), bluetooth or similar techniques, UE can use these technology for detection adjacency.A known small scale wireless network can be discerned as UE,, this recognition result can be in proximity detection, utilized then as bluetooth or wlan network.UE also can move the particular UE application technology, and this application technology can provide its information relevant with the adjacency of private base station to UE, such as, when can be used as remote controllers, UE is used for opening the garage, the Qianmen, or during the equipment of other Long-distance Control.
Because adding or other cell layout of new sub-district are reshuffled, the plot planning of public network also needs to upgrade sometimes.When this situation took place, the relation between dedicated cell and the public network sub-district also may change, as shown in Figure 3.
As can be seen from Figure 3, reconfigure front and back in the sub-district, the different districts in dedicated cell and the public network overlaps in together, is sub-district 1 and sub-district 2 among the figure.
Under situation shown in Figure 3, UE may attempt to utilize its cell relation information to search for private base station, but because change has taken place the layout of sub-district, the adjacency indication is not called, and UE will can not search for private base station.
In one embodiment of the invention, after cell layout reconfigured, the cell information of broadcasting comprised the cell information of new cell information and the preceding sub-district of configuration, promptly old cell information.This extra information will be broadcasted a period of time, and UE just can know which associated cell information they need upgrade.
If during this period of time, UE does not obtain this extra information, and UE just has to manually select dedicated cell so, upgrades cell relation information.Below situation under also can make in this way, at home or in the building, the owner of private base station has moved the position with private base station, also can change the relation of sub-district.
Among the present invention, the advantage that keeps cell relation information to upgrade is, proximity detection can be always based on the cell relation information of continuous renewal.
According to embodiments of the invention, proximity detection can be initiated or carry out to common network node.
Typically, have the UE that is in idle pulley in a large number in the network, it is mutual that these UE and network carry out finite information.Therefore when occurring being in the UE of idle pulley in a large number, should avoid a large amount of signaling traffic loads.
Therefore, according to embodiments of the invention, UE has when registering among the TA of same geographical coverage area with dedicated cell, and network has the dedicated cell that inserts authority for UE provides search parameter to come order UE to search for it.More excellent method is to utilize the TA in the network to upgrade (TAU) response message.
Using the TA signaling to provide the advantage of search parameter to be, can utilize existing Signalling exchange, is exactly the existing signaling of system as the tracing section updating signaling.
Yet because the overlay area of TA is quite big, and UE is its dedicated cell of search in whole TA, so the battery effect can not be always very high.
According to one embodiment of present invention, CN further sends request as the response to TAU to UE.When this request requires UE to enter the specific cell of TA (or any sub-district in a certain tabulation, this tabulation comprises a plurality of sub-districts), send extra TAU information.When UE enter with UE have the dedicated cell that inserts authority near or the sub-district of direct neighbor, be required in this sub-district, to send extra TAU information.Come the extra TAU message of last TAU response message response of automatic network, comprised in this response message that order UE searches for the search parameter of specific dedicated cell.
Further, according to from the measurement report that is positioned near the UE dedicated cell, that be in activity pattern, network can be that this dedicated cell is set up and upgraded cell relation information.Especially very useful to the sub-district relevant information that maintenance is used for proximity detection from the neighboring cell measurement reporting of UE, UE belongs to the closed user group that allows to use private base station here.
As mentioned above, for each UE, network control proximity detection or the gravity treatment of network control sub-district all have the advantage that is highly susceptible to combining with closed user group and carries out.
Also available a kind of mixed method is carried out proximity detection.At the private base station that UE can visit, network upgrades in the response message at TAU provides the cell relation information relevant with the dedicated cell peripheral cell for UE.Like this, just be responsible for judgement and when begin search private base station by UE.
The advantage of mixed method is that the signaling spending is littler than pure network control proximity detection.Simultaneously, UE need be in a very long time stored network information and the closed user group information that may also have yet, thereby reduced the out-of-date risk of UE canned data.
According to embodiments of the invention, the network node of carrying out proximity detection also can be an external electrical entity, identifies the user in the present dedicated cell overlay area.For example, as external electrical entity with proximity detector function, can be an alarm, as motion detector, reporting to the police starts/stops, the garage is imported and exported and is started, electron key system, vehicle detection, refrigerator open detector, voice detector, stereophonic sound system/radio system/personal computer/light detector or other similar devices.
Those skilled in the art can know have a large amount of external electrical entities to can be used for determining UE user's position, and these electronic entities may comprise various transducers.Those skilled in the art will know that except that above-mentioned electronic entity the transducer in other external electrical entities also is easy to be used for realizing the present invention.
The proximity detection indication that the external electrical entity produces can send extraneous information to UE by trigger network, and this information is relevant with the dedicated cell availability.As above-described, UE can use these information to judge whether to search for and measure the private base station that this UE has the access authority and closes on this UE present position.
The advantage of using the external electrical entity to carry out proximity detection is, can use in a plurality of domestic. applications, or the following cheap sensor technology that can be applicable in numerous household equipments.
In the embodiments of the invention, proximity detection also can be carried out by private base station.In an embodiment of the present invention, private base station provides the relevant information that detects via public base station to UE, and it is the same that the method that provides detects adjacency with public base station.Private base station detects via public base station notice UE adjacency, and order UE begins to search for private base station.
At present, the ownership of private base station and indeterminate.A kind of possible situation is that the owner has the private base station that is placed in its family too.Can not expect that the owner carries out the complicated network planning and configuration effort to dedicated cell as the network operator, therefore from owner's angle, the configuration that the dedicated cell needs can be autonomous.Since the owner can be placed on private base station any suitable place, from network operator's angle, the coverage of dedicated cell is less than certain planning.
Fig. 4 has provided an example, and two dedicated cells (sub-district 1 and sub-district 2) and a common cell (sub-district 3) are arranged here, and wherein dedicated cell is covered by private base station.
Dedicated cell and near sub-district can not have direct covering relation, and as the dedicated cell among Fig. 42, promptly it can not have direct neighbor cell.When being placed on the basement in house, private base station just may occur that.
Among Fig. 4,, will can not keep in touch with network for some time when the UE that is in idle condition 3 roams into sub-district 2 from the sub-district.Network also paging less than this UE, i.e. UE " not at the area of coverage ".In public communication system, when UE finds own out of reach, in a period of time, will attempt to seek its original sub-district (sub-district 3), carry out search then to other sub-districts.
According to embodiments of the invention, UE carries out the detection of adjacency based on the state of such common cell coverage condition.Especially, as a kind of special circumstances of proximity detection, when the UE out of reach, UE preferentially detects its known and dedicated cell that have the access authority.More precisely, its dedicated cell known, that do not have the direct neighbor sub-district of UE first search.
According to cell relation information using method described above, if UE has further understanding to peripheral cell, UE utilizes these understanding further to determine which sub-district of search.
Document [4] has proposed to send clear and definite sub-district priority to UE.In an embodiment of the present invention, this thought is expanded to also comprising as the adjacency indication of selecting priority.
According to embodiments of the invention, by comprising the coverage condition state parameter in the proximity detection, than the situation of UE without any the ferret out clue, the speed that this moment, UE recaptured service can be accelerated probably significantly.
In an embodiment of the present invention, the time interval of twice dedicated cell gravity treatment search is depended on the distance between UE and the private base station.Distance hour, the time interval is shorter relatively, on the contrary, the time interval was longer relatively when distance was big.
In the embodiments of the invention, UE is instructed to or storage and the relevant extraneous information of dedicated cell coverage condition situation, and promptly dedicated cell is " can serve " or " can not serve ".When UE is in the coverage of other sub-district, and dedicated cell be during for " can not serve ", and UE utilizes these extraneous informations, thereby does not search for dedicated cell.Therefore, according to the embodiment of the invention, when private base station " can not be served ", do not need to carry out unnecessary search.
Further, when dedicated cell is configured to a kind of interference reduction pattern, private base station may be sightless concerning UE.
According to embodiments of the invention, UE may know its be in private base station near, still can attempt to seek discontinuous transmission (DTX) pattern of this private base station, and send to private base station and to insert pulse at random, this inserts pulse at random and may have special leadingly, changes private base station over to normal mode of operation.When private base station " can not be served ",, can use said method if private base station is closed or be in other power protected modes at that time.
Especially, this need be very important under the situation of the private base station transmission urgent call that can not serve at UE.Use embodiments of the invention, increased the possibility of carrying out urgent call in the dedicated cell.
Therefore, the present invention relates to a kind of being used for is in the system that the subscriber equipment (UE) of idle pulley carries out the dedicated cell gravity treatment at public network, public network comprises a public base station that covers common cell at least, UE also can be used for and dedicated network communicates, dedicated network comprises a private base station that covers dedicated cell at least, and UE has limited access authority in dedicated network; Wherein:
-UE is used for: only when contiguous its of UE has the private base station that inserts authority, carry out dedicated cell gravity treatment search;
-network node only is used for carrying out communicating by letter of dedicated cell gravity treatment search with described UE when contiguous its of UE has the private base station that inserts authority, and this UE has the access authority of dedicated cell;
Here proximity detection based on UE with and with the information of the relation of private base station.
The invention still further relates to the UE of execution sub-district gravity treatment and the correlation method and the device of network node.
Carry out the UE of dedicated cell gravity treatment and any step that network node can be used for carrying out the inventive method among the present invention.Unique requirement is that this step comprises this UE or network node.
Those skilled in the art can make amendment to dedicated cell reselecting method of the present invention according to embodiment described above.
