Hereinafter, the part term in the application is explained, in order to skilled artisan understands that.

1) terminal, refers to the equipment for providing a user voice and/or data connectivity, for example, can include the portable equipment with wireless connecting function or be connected to the processing equipment of radio modem.The terminal can be communicated through RAN with core net, and voice and/or data are exchanged with RAN.The terminal is properly termed as UE (user equipment, user equipment), wireless terminal, mobile terminal, subscri er unit (Subscriber Unit), subscriber station (Subscriber Station), movement station (Mobile Station), mobile station (Mobile), distant station (Remote Station), AP (Access Point, access point), remote terminal (Remote Terminal), access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent), or subscriber's installation (User Device) etc..For example, it may be mobile phone (or being " honeycomb " phone), the computer with mobile terminal, portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device.For example, PCS (Personal Communication Service, PCS) phone, wireless phone, SIP (Session initiation Protocol) phone, WLL (Wireless Local Loop, WLL) stand, the equipment such as PDA (Personal Digital Assistant, personal digital assistant).

2) RAN equipment, refers to the equipment that terminal is linked into wireless network, and it passes through one or more sectors and terminal communication on interface in the air.The RAN equipment for example can be：ENB (evolved Node B, evolved node B), RNC (radio network controller, radio network controller), NB (Node B, node B), BSC (Base Station Controller, base station controller), BTS (Base Transceiver Station, base transceiver station), Home eNodeB (for example, Home evolved NodeB, or Home Node B, HNB), Wifi AP (Access Point, access point) etc..In addition, the radio reception device can also be BBU (BaseBand Unit, Base Band Unit).

3) term " system " and " network " in the application can be used interchangeably." multiple " refer to two or more."and/or", describes the incidence relation of affiliated partner, expression may have three kinds of relations, for example, A and/or B, can be represented：Individualism A, while there is A and B, these three situations of individualism B.In addition, character "/", unless otherwise specified, it is a kind of relation of "or" to typically represent forward-backward correlation object.

Existing ANR flows are introduced first.

ANR includes ANR between ANR and system in system, ANR is used for the completeness and efficiency of neighboring BS relationship in automatic maintenance system wherein in system, for example, LTE (Long Term Evolution, Long Term Evolution) system, or the neighboring BS relationship in referred to as E-UTRAN (Evolved Universal Terrestrial Radio Access Network, evolved Universal Terrestrial wireless access network) system.ANR is used for the completeness and efficiency of neighboring BS relationship between automatic maintenance system between system, for example, neighboring BS relationship between LTE system and 2G/3G systems, or the neighboring BS relationship referred to as between E-UTRAN systems and GERAN/UTRAN/CDMA2000 systems, wherein GERAN refers to GSM/EDGE RAN (Global System for Mobile communication/Enhanced Data rates for GSM Evolution wireless access networks, GSM EDGE Radio Access Network), UTRAN refers to Universal Terrestrial Radio Access Network (Universal Terrestrial wireless access network), CDMA refers to Code Division Mulitple Access (CDMA).

In ANR technologies, two basic lists of RAN plant maintenances, i.e. NCL (neighboring cell list, Neighboring Cell List) and NRT (Neighboring Relation Table, neighborhood region correlation chart).Wherein, NCL is External cell list in non-RAN equipment, each RAN equipment has the different system NCL of NCL and different systems in a system.NCL records CGI (the Cell Global Identifier of external cell in system, Cell Global Identification), PCI (Physical Cell Identifier, Physical Cell Identifier), the information such as frequency, RAN equipment is (for example, eNB) external cell for detecting UE is added in NCL, is used as the foundation for setting up neighboring BS relationship.The different system NCL of GERAN have recorded cell ID (indentifier, mark), BSIC (base transceiver station identity code, base station identity code) and frequency etc..The different system NCL of UTRAN have recorded the information such as cell ID, scrambler, frequency.The different system NCL of CDMA have recorded the information such as cell ID, frequency, Physical Cell Identifier.In RAN device activation systems between ANR or system after ANR, it can automatically increase, delete NCL.NRT describes the neighboring BS relationship that this cell and other cells are constituted, including the interior neighboring BS relationship between station in station.Each cell has the different system NRT in a system with alien frequencies NRT in frequency NRT, system (NRT in general designation system) and different systems.

A kind of existing ANR flows are described by taking ANR processes in system as an example below：

Fig. 1 is refer to, it is ANR schematic flow sheets in a kind of existing system.As shown in figure 1, the ANR flows comprise the following steps：

S101：After terminal networks, the metrical information of RAN equipment (i.e. RAN network elements in Fig. 1) meeting sending measuring information, such as event A1, A2 and A3 in reallocation message, what it is due to addition is alien frequencies adjacent area, therefore pays close attention to event A2 measurements.

S102：Terminal reports A2 events, and RAN equipment can be promoted to issue A4 measurements.

Wherein, the object of event A1, A2 and A3 measurement is the current area where terminal, and the object of event A4 measurements is the ID of adjacent area.

S103：RAN equipment issues event A4 metrical information in reallocation message.

S104：When terminal detects the signal of adjacent area, A4 reporting events are carried out.Here detect the signal of adjacent area can refer to adjacent area signal it is good enough, i.e., when the adjacent area detected signal intensity be more than preset value when, report A4 events.

S105：RAN equipment is received after the A4 reporting events, and discovery does not recognize the adjacent area, i.e., the adjacent area is not in NRT, then terminal will be allowed to go to check the mark of the adjacent area (hereinafter referred to as unknown cell), Namely survey its CGI.Specific RAN equipment goes to check the mark of unknown cell by following steps S106 triggering terminals.

S106：RAN equipment issues the metrical information of unknown cell in reallocation message, for example, CGI metrical informations.

S107：Terminal obtains the mark of unknown cell, such as CGI from system message, SIB1 (System Information Block 1, System information block 1).

S108：The mark of unknown cell, such as CGI are reported RAN equipment by terminal by measurement report.

Because RAN equipment allows the cell of switching to be to set up the cell of neighboring BS relationship in NRT.If ANR functions are not opened, terminal is not allow to be switched to the unknown cell；If ANR functions are opened, RAN equipment automatically will add this unknown cell in NRT, switch over.Preparation more than, terminal can be carried out have switched to the cell.

ANR is similar with ANR in system between system, and difference is, when issuing the reallocation message of A4 measurements, it is necessary to while B1 and most strong cell event be issued, here, being no longer described in detail.

It can be seen that, in existing procedure, the adjacent area for measuring signal directly can be added in NRT by terminal.

And in actual applications, due to there is the scenes such as super remote covering, area covered, the signal of super remote cell is also fine, it can be measured and be added in NRT by terminal.But should not have handoff relation between the cell and super remote cell where terminal, that is to say, that it is inaccurate that super remote cell is added into adjacent area.It can be seen that, there is the problem of neighboring BS relationship safeguards inaccurate in existing ANR technologies, the addition of these adjacent areas in addition wastes storage resource, and unnecessary influence can be also caused when terminal is switched over to the switching.

In addition, prior art can also safeguard NRT behind addition adjacent area according to certain rule.For example, the switch data of statistics some cycles, measurement data, undesirable adjacent area is deleted according to the situation of statistics.If for example, terminal is not switched to some adjacent area for a long time, the adjacent area is deleted from NRT；Such as, if terminal does not measure the signal of some adjacent area again for a long time, the adjacent area, etc. is deleted from NRT.

In such a mode, as long as the cell that terminal is measured will be added in NRT, and later stage attendant is when being safeguarded, or some addition super remote cell due to not no cutting as terminal for a long time When changing selection, the super remote cell of the addition may be deleted from NRT, and after deleting, if terminal has measured the signal of the super remote cell again, the cell can may be added in NRT again, that is, the defect that there are table tennis additions and deletions, and burden is caused to RAN equipment.

Further, since PCI (Physical Cell Identity, Physical Cell Identifier) limited amount, if in the Neighboring Cell List of the cell where substantial amounts of super remote cell being added to terminal, then probably due to the cell of addition is excessive, cause PCI largely to conflict, influence O＆M.

The application fully takes into account problem above, after knowing that terminal measures the signal of some cell and reports the cell to RAN equipment, the positional information of cell where RAN equipment obtains the positional information and terminal of the cell, and directly filtered out the cell that position is not suitable for being configured to adjacent area using these positional informations, to be not added in NRT, so as to automatically configure out more accurate neighboring BS relationship.

The embodiment of the present invention is described in further detail with reference to Figure of description.

Fig. 2 is referred to, it provides the flow chart that a kind of adjacent area determines method for the embodiment of the present invention, as shown in Fig. 2 this method mainly comprises the following steps：

S201：RAN equipment receives the first community mark that the terminal in its coverage is reported.

S202：RAN equipment obtains the second place information that the first community identifies the second community where the first position information and terminal of corresponding first community.

S203：RAN equipment is according to first position information and second place information, it is determined whether regard the first community as the adjacent area of second community.

Above first community mark e.g. CGI.And obtaining for cell ID can carry out measurement (for example, CGI is measured) realization of unknown cell by RAN equipment instruction terminal.The corresponding descriptions of Fig. 1 specifically are may be referred to, be will not be repeated here.

The mode that above step S202, i.e. RAN equipment obtain the second place information of second community where first community identifies the first position information and terminal of corresponding first community can be diversified.Several exemplary implementations given below：

The first implementation：The position configuration information in the region that one where RAN equipment has been planned imported into RAN equipment, in this way, RAN equipment is when needed, the positional information of cell needed for just can inquiring about.Such as form of the position configuration information is { cell ID, positional information }, and it represents cell mark Know the corresponding relation with positional information.Wherein, cell ID is, for example, CGI, and positional information is, for example, Ellipsoid-Point, is a kind of by way of the position for the cell that longitude and latitude is represented.

Now, RAN equipment is stored with the position configuration information in the region, the position configuration information includes the cell ID and the corresponding relation of positional information of each cell in all cells in the region, and the second place information of the second community where the first position information and terminal of the corresponding first community of the RAN equipment acquisition first community mark, including：

RAN equipment searches first community in the configuration information of above position and identifies corresponding positional information, regard the positional information found as the first position information；And the corresponding positional information of cell ID of second community is searched in the configuration information of above position, it regard the positional information found as the second place information.

It should be noted that RAN equipment can safeguard the mark of all cells under it, and RAN equipment is when terminal accesses its lower cell, the relevant information of meeting maintenance terminal, therefore RAN equipment knows which cell is the serving cell of the terminal certainly, i.e. second community.Therefore, RAN equipment just can be according to its corresponding positional information of the identifier lookup of the second community.

It should be noted that the mode that above position configuration information can import work ginseng by OSS (Operations Support System, OSS) is imported into RAN equipment.It is of course also possible to import otherwise, the present embodiment does not do any limitation.

Second of implementation：The first position information of first community and the second place information of second community are obtained by different modes.The second place information of second community can be read by GPS (Global Positioning System, global positioning system)；Or the local position configuration information of RAN equipment can be imported into RAN equipment, the cell ID and the corresponding relation of positional information of the local position configuration information each cell in all cells including the RAN equipment.In this way, RAN equipment is when needed, the positional information of the cell of the RAN equipment just can be inquired about.The form of the form of position configuration information position configuration information in the first implementation with more than, is { cell ID, positional information }.

Now, RAN equipment is stored with local position configuration information, the second place information of second community where the cell ID and the corresponding relation of positional information of the local position configuration information each cell in all cells including the RAN equipment, and RAN equipment acquisition terminal, including：

RAN equipment searches the corresponding positional information of cell ID of second community in above local position configuration information, regard the positional information found as the second place information.

It should be noted that importing of the importing of above local position configuration information with the position configuration information of area above, the mode that work ginseng can be imported by OSS (Operations Support System, OSS) is imported into RAN equipment.It is of course also possible to import otherwise, the present embodiment does not do any limitation.

In addition, if first community is also the cell of the RAN equipment, then, to obtain the first position information of the first community, it can be will not be described in detail herein by the second place information identical mode with second community.

The first position information of first community can be obtained by the interaction of RAN equipment and other network equipments (RAN equipment is also a kind of network equipment, and other network equipments refer to the network equipment in addition to the RAN equipment).Or, RAN equipment can utilize before some flows in information exchange obtain the first position information, and the first position information is stored in locally, during so as to follow-up needing, directly obtains and use from local.

It can be seen that, RAN equipment can be from the second place information of the local first position information and second community for obtaining first community；It can also obtain the first position information of first community from other network equipments, and from the local second place information for obtaining second community.That is, RAN equipment can be from the local second place information for obtaining the second community where terminal, and as the first position information of first community, RAN equipment can also can be obtained from local acquisition from other network equipments.It is introduced individually below.

Optionally, in the embodiment of the present invention, if RAN equipment is from the local first position information for obtaining first community, in the RAN equipment before the first position information is locally obtained, in addition to：

RAN equipment receives and stored the positional information of its all cell sent with the RAN equipment belonging to first community when being connected with the RAN equipment foundation belonging to first community；

RAN equipment receives and stored the positional information of its all cell sent with the RAN equipment belonging to first community after being connected with the RAN equipment foundation belonging to first community.

Wherein, in all cells of the RAN equipment belonging to first community, the positional information storage corresponding with cell ID of each cell.In this way, the RAN equipment where terminal just can be identified according to first community, Its corresponding positional information, as first position information are searched from the positional information of storage.

It should be noted that when above RAN equipment is LTE eNB, X2 connections are connected as above.

RAN equipment will be carried in RIM (RAN Information Management for the request message of the positional information of acquisition request first community, wireless access network information management) in message, the RIM message is sent to by MME by the RAN equipment belonging to first community.

Specifically, the interaction on the first situation under the second way refers to Fig. 7.

In Fig. 7, middle eNB represents the RAN equipment where terminal, RAN equipment i.e. in Fig. 2 flows, RNC (the Radio Network Controller on the right, radio network controller)/BSC (Base Station Controller, base station controller) represent first community belonging to base station.First, eNB triggering terminals start unknown cell measurement, i.e., issue MeasureConfigure message to terminal, terminal is connected to after MeasureConfigure message, starts to measure cell, if terminal has been measured except its service is small The signal of other cells outside area, the then cell ID (for example, CGI) that terminal is arrived to eNB reporting measurements.ENB is received after the cell ID that terminal is reported, and preserves the cell ID that terminal is reported.And, eNB can send position requests to RNC/BSC, specifically, eNB can carry position requests in RIM message (for example, eNB Direct Information transfer (transmission of base station direct information) message in Fig. 7) in, eNB Direct Information transfer message is sent to MME, position requests therein are carried and are sent to RNC/BSC in Direct Information transfer message by MME, RNC/BSC is after Direct Information transfer message is connected to, Direct Information transfer message is replied to MME, in the Direct Information transfer message of reply, carry the positional information that eNB is asked, such as eNB can simply request the positional information of the corresponding cell of cell ID, or eNB can also ask the positional information for each cell that the RAN equipment belonging to the corresponding cell of cell ID covers, MME is after the Direct Information transfer message of RNC/BSC replies is received, positional information therein is carried and is sent to eNB in MME Direct Information transfer (transmission of mobile management entity direct information), eNB preserves the positional information received.

In table 9, Semantics description fields include Contains the BSSGP RIM PDU as Defined in TS (include the time quantum defined in GPRS (GeneralPacketRadioService, GPRS) agreement RIM protocol Data Units).

Below to above step S203, i.e., RAN equipment is according to first position information and second place information, it is determined whether using the first community as the adjacent area of second community, be described in detail.

RAN equipment just can determine the distance between first community and second community after first position information and second place information is obtained according to these positional informations, and distance then is met into desired first community as the adjacent area of second community, that is, is added in NRT；The first community for being unsatisfactory for requiring is filtered out, not as the adjacent area of second community, that is, is not added in NRT.

It is required that preparatory condition can be set to according to actual needs, the preparatory condition can be：Identified distance is less than or equal to pre-determined distance；Or, identified distance is less than or equal to the radius sum of first community and second community；Or, identified distance is less than or equal to the adjusted value of the radius sum of first community and second community, and the adjusted value is multiplied by predetermined coefficient for the radius sum of first community and second community.

For example, with r₁The radius of society of first community is represented, with r₂The radius of society of second community is represented, predetermined coefficient is represented with a, the distance between first community and second community are represented with D, then, refer to equation below：

D<a(r₁+r₂) (1)

Only when D meets formula (1), first community can just be added to the adjacent area of second community by RAN equipment, if D is unsatisfactory for formula (1), then first community will not be added to the adjacent area of second community by RAN equipment.

Predetermined coefficient can be set according to actual conditions, such as the larger cell of radius, then a value can be with slightly larger, and for the less cell of radius, then a value can be with slightly smaller, etc..

Now, the positional information of any of the above cell can also include the radius of the cell.

It should be noted that the positional information of any of the above cell can be represented using longitude and dimension.It is to calculate spherical distance according to the longitude and dimension of the two cells to calculate to realize that then now the distance between two cells, which are calculated,.For example, it is assumed that the longitude and latitude of first community is x1, y1, radius of society is r1, the The longitude and latitude of two cells is x2, and y2, radius of society is r2, then the calculation formula equation below (2) of 2 points of distance on sphere：

D=R*arccos (cos (x1* π/180) * cos (x2* π/180) * cos (y1* π/180-y2* π/180)+sin (x1* π/180) * sin (x2* π/180)) (2)

Wherein, D represents the distance between two cells, and R is earth radius, and R=6370996.81.

In the embodiment of the present invention, in order to further avoid super remote cell being added to adjacent area, it can also take some measures, two ways introduced below.

First way：

Optionally, in the embodiment of the present invention, RAN equipment is obtained before first position information and second place information, in addition to：

RAN equipment obtains the positional information of N number of terminal, and N number of terminal has carried out unknown cell measurement, and has reported above first community to identify to the RAN equipment, and wherein N is the positive integer more than or equal to 2；

RAN equipment determines that the position of N number of terminal meets setting relation according to the positional information of N number of terminal of acquisition.

That is, if RAN equipment receives the cell ID that multiple terminals are reported, and therein have that N number of terminal reports is same cell ID.If this is the case, so RAN equipment is before step S202 is performed, the positional information of this N number of terminal can be obtained first, then, RAN equipment may determine that in this N number of terminal whether the distance between terminal meets setting two-by-two and set relation, if meeting, so RAN equipment can continue executing with step S202, obtain first position information and second place information, and if the distance between terminal is unsatisfactory for setting relation two-by-two in this N number of terminal, then RAN equipment can need not perform step S202, you can to terminate flow.

Optionally, in the embodiment of the present invention, set relation as：The distance between each two terminal is all higher than being equal to predetermined threshold value in N number of terminal.

Because for super remote cell, there may come a time when that having the terminal in some region measures its signal, and the terminal in other region will not then measure the signal of the super remote cell.So, if multiple terminals report same cell ID, then RAN equipment can determine the position relationship of these terminals, it can for example determine whether between any two sufficiently distant apart these terminals, if the position of these terminals meets setting relation, it is considered that these terminals are between any two sufficiently distant apart, then at a distance of enough Remote terminal can measure the signal of a cell, illustrate the cell be not super remote cell possibility it is larger, then RAN equipment can proceed other steps in above example of the present invention, and if the position of these terminals is unsatisfactory for setting relation, then it is considered that closer to the distance between certain two terminal in these terminals, it is just in the region that can be measured that some super remote cell, so it is considered that cell ID that these terminals are reported is the cell ID of a super remote cell, so RAN equipment can determine not to be added to the cell ID corresponding cell the adjacent area of the cell where terminal, also just without performing follow-up step again.

The second way：

Optionally, in the embodiment of the present invention, RAN equipment is determined whether first community as the adjacent area of second community, including：

RAN equipment determines whether the position of N number of terminal meets setting relation according to the positional information of N number of terminal of acquisition；

If the position between N number of terminal meets setting relation, RAN equipment determines to regard first community as the adjacent area of second community.

I.e., under the first technique, RAN equipment is whether the position for first judging N number of terminal meets setting relation, if the cell and first community where judging terminal if meeting again identify whether the distance between corresponding cell meets preparatory condition, and under a second technique, RAN equipment can first judge that cell and first community where terminal identify whether the distance between corresponding cell meets preparatory condition, if meeting, then judge whether the position of N number of terminal meets setting relation.Both modes, can choose any one kind of them in implementing.

Equivalent to determining whether a cell meets switching and require using two deterministic processes in the embodiment, make the result of determination more accurate.

In addition, terminal location utilized above switches a kind of method that desired method can be determined independently as adjacent area to determine whether a cell meets.That is, the application also provides another adjacent area and determines method, and it is filtered out using the positional information of terminal is measured by terminal but do not meet the cell that switching is required, it is former Reason is as follows：

If there is super remote cell in network, then the signal of the super remote cell is generally only detected in some point by some terminal, in order to filter out such a data, it is considered to improve the reliability of measurement using terminal positional information.After RAN equipment receives the unknown cell mark that terminal is reported, store dynamic adjacent area table, if terminal supports MDT (Minimization of Drive Tests minimize drive test), then RAN equipment sending measuring control carrying reports MDT (reportMDT) instruction.After terminal reporting position information, storage location information (for example, storage is arrived under the table of dynamic adjacent area).After the positional information for collecting 3 terminals, if the distance of each two terminal is all higher than a threshold value, then it is assumed that the unknown cell is credible cell, otherwise only exist in dynamic adjacent area table, used not as formal adjacent area, investigating can be deleted or be added in NRT after some cycles.The threshold value can be set as that the 1/N of radius of society, N are positive integer according to real network situation.

Specifically, Fig. 8 is referred to, it provides the flow chart that another adjacent area determines method for the embodiment of the present invention, the main flow of methods described is as follows.

S801：RAN equipment determines to report N number of terminal of same cell ID in the RAN equipment coverages, and N is the integer more than or equal to 2.Hereinafter referred to as the same cell ID identifies for first community；

S802：RAN equipment obtains the positional information of N number of terminal；

S803：RAN equipment is according to the positional information of N number of terminal, it is determined whether the adjacent area of the cell where first community is identified into corresponding cell as N number of terminal.

Optionally, in the embodiment of the present invention, RAN equipment is according to the positional information of N number of terminal, it is determined whether the adjacent area of the cell where first community is identified into corresponding cell as N number of terminal, including：

RAN equipment determines that the position of N number of terminal meets setting relation, then RAN equipment determines the adjacent area of the cell where first community is identified into corresponding cell as N number of terminal.

Optionally, in the embodiment of the present invention, set relation as：The distance between each two terminal is all higher than or equal to predetermined threshold value in N number of terminal.

That is, if RAN equipment receives the cell ID for the unknown cell that multiple terminals are reported, and therein have that N number of terminal reports is same cell ID.If it is the case, so RAN equipment can obtain the positional information of this N number of terminal, it can be determined that whether the position of this N number of terminal meets setting relation, If meeting, so the corresponding cell of the cell ID can be added to the adjacent area of the cell where N number of terminal by RAN equipment, and if the position of this N number of terminal is unsatisfactory for setting relation, then the corresponding cell of the cell ID can not be added to the adjacent area of the cell where N number of terminal by RAN equipment.

Because for super remote cell, there may come a time when that having the terminal in some region measures its signal, and the terminal in other region will not then measure the signal of the super remote cell.So, if multiple terminals report same cell ID, then RAN equipment can determine the position relationship of these terminals, it can for example determine whether between any two sufficiently distant apart these terminals, if the position of these terminals meets setting relation, it is considered that these terminals are between any two sufficiently distant apart, terminal so sufficiently distant apart can measure the signal of a cell, illustrate the cell be not super remote cell possibility it is larger, then the corresponding cell of the cell ID can be added to the adjacent area of the cell where terminal by RAN equipment, and if the position of these terminals is unsatisfactory for setting relation, then it is considered that closer to the distance between certain two terminal in these terminals, it is just in the region that can be measured that some super remote cell, so it is considered that cell ID that these terminals are reported is the cell ID of a super remote cell, so RAN equipment can determine not to be added to the cell ID corresponding cell the adjacent area of the cell where terminal.

It should be noted that the cell ID of any cell in all embodiments of the application can be CGI or ECGI.

The equipment in the present invention is introduced below in conjunction with accompanying drawing.

Fig. 9 A are referred to, based on same inventive concept, the embodiment of the present invention provides a kind of RAN equipment, here RAN equipment can be any RAN equipment as described in preceding embodiment, for example can be base station, preferably, the RAN equipment can be and the RAN equipment corresponding to Fig. 2 flows.The RAN equipment can include receiving module 901, acquisition module 902 and determining module 903.
