Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

In the embodiment of the present invention, before Home eNodeB HNB starts shooting, the positional information of user equipment (UE) can be obtained by secondary satellite navigation system, and the historical position information of the positional information of UE as UE is preserved.Utilizing secondary satellite navigation system to obtain UE positional information (namely being got the positional information of UE by A-GNSS/GPS method) can comprise based on UE mode and UE supplementary mode, see Fig. 1, for obtaining the flow chart of UE positional information in A-GNSS/GPS based on UE mode.

In another embodiment of the invention, UE positional information described herein comprises: geographical location information (such as, certain street house number information), or latitude and longitude information etc.

101: user equipment (UE) gets the positional information of this community from the base station of its community, place, the positional information of this community is sent to service wireless network controller (SRNC, Serving Radio Network Controller).

Wherein, the positional information of community comprises: the geographical location information etc. of community.Community herein not is the Home eNodeB HNB community not determining positional information, and refer to before this HNB starts shooting, the base station cell at UE.That is, because HNB does not also start shooting at present, do not register, also just there is no UE switching or gravity treatment in this HNB base station cell.

102: service wireless network controller SRNC is according to the positional information of this community, call the Serving Mobile Location Center (SMLC that UE is corresponding, Serving Mobile Location Centre) resource, obtain this community can satellite information (i.e. GPS supplementary), and the satellite information got is returned to UE.

The satellite information of SMLC inquiry can comprise: the information such as frequency range, orientation, the elevation angle of satellite.Satellite information also can be the auxiliary data information after network side processes the satellite information obtained, auxiliary data information can be: 1) measure the auxiliary data used, as the reference time, usable satellite list, satellite signal Doppler skew, code phase etc.; 2) auxiliary data of location estimation average computation is provided, as satellite ephemeris, reference position, clock correction etc.

103:UE searches current available GNSS/GPS satellite according to this satellite information, and utilizes available GNSS/GPS satellite to carry out the pseudo range measurement of satellite, obtains pseudo-range information, utilizes this pseudo-range information to calculate the positional information of UE.

Wherein, when pseudo range measurement refers to and carries out Navigation and localization by global positioning system, by the pseudo noise code of satellite broadcast and the correlation technique of receiver replica code, measure the distance between measuring station (being UE) and satellite herein.Owing to containing the distance due to clocking error and atmospheric refraction delay in the distance that pseudo range measurement goes out, the range information therefore utilizing pseudo range measurement to obtain can be called pseudo-range information.

The UE positional information that 104:UE is calculated reports network side.

Wherein, network side can be: radio network controller SRNC.Certain network side also can be other network equipments.UE positional information is sent to network side by UE, so that network side can get the positional information of UE.

It should be noted that, the mode utilizing A-GNSS/GPS to obtain UE positional information can also be: the UE positional information that UE supplementary mode obtains, namely, after completing pseudo range measurement by UE, the data such as the pseudo-range information of measurement are sent to service wireless network controller SRNC by UE, are utilized the data such as pseudo-range information to calculate the positional information of UE by SRNC or SMLC.

Unlike the prior art, the embodiment of the present invention, after getting the positional information of UE by above-described A-GNSS/GPS system, can preserve the UE positional information got.The mode of preserving UE positional information can have multiple, Ke Yiwei: after the mode auxiliary by UE gets UE positional information, the historical position information of the positional information of the UE of acquisition as UE is preserved by SMLC.In other words, before UE is switched to this HNB community, the mode can assisted by UE gets the positional information of UE, and is preserved by the historical position information of UE positional information as UE by SMLC.Because the positional information of UE can change, the positional information of the UE got for the last time in SMLC, only can be preserved.Such as, the positional information of preserving certain user equipment (UE) 1 in SMLC is location1, after the position of this user equipment (UE) 1 changes, the positional information again being got this UE1 by A-GNSS/GPS is location2, then UE1 positional information then saves as by SMLC: location2.Further, the UE positional information in setting-up time can also be preserved in SMLC, that is, only the positional information of the UE in setting-up time is preserved as historical position information.As, the positional information of the UE before only preserving current time in 10 seconds.

Obtain UE positional information based on UE supplementary mode, for after UE gets pseudo-range information, pseudo-range information can also be sent to SRNC, calculated the positional information of UE by SRNC.Unlike the prior art, in the embodiment of the present invention, service wireless network controller SRNC can preserve the positional information of the UE that it calculates.That is, the historical position information of the positional information of the UE calculated as UE is preserved by SRNC.Similar to the mode that SMLC preserves the historical position information of UE, for the last positional information that a certain UE, SRNC only can preserve this UE, the positional information of the UE in the scheduled time also can be preserved.

Certainly, its positional information can also be preserved by UE, after UE enters wireless network, network side (this network side can be SRNC) sends the message of preserving this UE positional information to this UE equipment, when getting the positional information of self based on UE mode during UE is by above-described A-GNSS/GPS method, UE can preserve its UE positional information got, and the UE positional information of this preservation is namely as the historical position information of UE.With to utilize SMLC to preserve UE positional information similar, UE only can preserve its UE positional information got for the last time; Certainly, UE also can preserve the UE positional information in setting-up time.

Certainly, the embodiment of the present invention is before Home eNodeB start, the mode of the positional information of subscriber equipment can also be got by other means to obtain the positional information of UE, and the historical position information of the positional information of the subscriber equipment got as subscriber equipment is preserved, so that the positional information of the positional information calculation Home eNodeB of later use subscriber equipment.

The embodiment of the present invention obtains the positional information of subscriber equipment by secondary satellite navigation system, and the historical position information of the positional information of subscriber equipment as subscriber equipment is preserved, when Home eNodeB HNB itself does not possess GNSS/GPS ability, or indoor environment residing for HNB poor time, HNB can utilize the historical position information of the subscriber equipment be switched in its community to calculate the positional information of HNB, see Fig. 2, it is the localization method schematic flow sheet of a kind of Home eNodeB of another embodiment of the present invention.

201: Home eNodeB detects the subscriber equipment be switched in home base station cells, using the subscriber equipment that detects as target UE.

Those skilled in the art is known, after Home eNodeB HNB succeeds in registration, can have successively in multiple UE switching or gravity treatment Dao Gai HNB community.When there being UE to be switched in this HNB community, this HNB can detect all user equipment (UE)s be switched in its community, and the relevant information of UE, as, the information such as the mark of UE, then using the subscriber equipment that is switched in this HNB community as target UE.

202: Home eNodeB, in the historical position information of the subscriber equipment got by secondary satellite navigation system preserved, obtains the historical position information of target UE.

After determining the target UE in this HNB community, HNB can obtain the historical position information of this target UE, and the historical position information of this target UE is the positional information of this target UE utilizing secondary satellite navigation system to get in advance.

Positional information in order to the positional information calculation of the UE be switched in this HNB community can be utilized to go out HNB before Home eNodeB start, need in the historical position information of the UE preserved, inquire the historical position information of the UE be switched in this HNB community, namely inquire the historical position information of target UE.That is, in the historical position information of the UE preserved, comprise the historical position information of a lot of UE, but be not that UE corresponding to UE historical position information preserved is switched in this HNB community, therefore need to inquire about the historical position information of the target UE be switched in this HNB community.Wherein, the historical position information of UE is for current time, and be the positional information of the UE obtained before HNB start at the historical position information of the UE preserved, after HNB start, some changes may occur the positional information of UE.More accurate in order to make utilization be switched to the positional information of the HNB that the UE historical position information in HNB community calculates, HNB can set the effective time of UE historical position information, namely, preserve the historical position information of the moment distance HNB acquisition UE of UE historical position information time be engraved in setting-up time length range, then think that UE historical position information was in effective time.As, the effective time that can set the historical position information of UE is 3 seconds, also can set the length of effective time according to actual needs.

The reason of the effective time of setting UE historical position information is: if the time of preserving the moment distance current time of the historical position information of UE is longer, such as be more than or equal to certain Preset Time, larger change may be there is in the positional information of UE, when now utilizing the historical position information of the UE got by secondary satellite navigation system preserved to calculate HNB positional information, the data obtained may be inaccurate.

When HNB obtains the historical position information of the UE be switched in this HNB community, can be: in the historical position information of the subscriber equipment got by secondary satellite navigation system preserved, the historical position information of query aim subscriber equipment, and in the historical position information inquired, obtain the historical position information be in effective time.In other words, even if certain UE has been switched in this HNB community at present, but the time span due to this UE historical position information moment distance current time preserved exceeds the effective time of the historical position information of setting, and HNB also can not obtain out the historical position information of this UE.

Such as, in the historical position information of the subscriber equipment preserved, preserve user equipment (UE) 1, user equipment (UE) 2, user equipment (UE) 3 and user equipment (UE) 4, and the subscriber equipment be switched in HNB community is only: UE1, UE2 and UE3, therefore HNB needs to inquire UE1 in the subscriber equipment preserved in advance, the historical position information of UE2 and UE3, and inquiring UE1, after the historical position information of UE2 and UE3, judge the UE1 preserved, whether the historical position information of UE2 and UE3 is all in historical position information effective time of setting, as, historical position effective time of setting is 5 seconds, the moment of preserving the historical position information of UE1 is 2011-4-12, 09:24:20, the moment of preserving UE2 historical position information is 2011-4-12, 09:24:18, the moment of preserving UE3 historical position information is 2011-4-12, 09:24:15, and the moment (current time) that HNB obtains the UE historical position information be switched in this HNB community is 2011-4-12, 09:24:21, therefore, the historical position information of the UE3 preserved is not within the effective time of the historical position information of setting, the historical position information of UE1 and UE2 should be comprised in the UE historical position information that final HNB obtains.

Wherein, after getting position information of user equipment by secondary satellite navigation system, the historical position information of the positional information of subscriber equipment as subscriber equipment is preserved, the position of concrete preservation can be the mode of the historical position information of preservation subscriber equipment described above, as the positional information of the subscriber equipment got by secondary satellite navigation system being kept at Serving Mobile Location Center as historical position information, certainly, wireless network control center can also be kept at, or the historical position information of oneself is preserved by subscriber equipment, certainly other modes can also be had, do not enumerate at this.

203: Home eNodeB utilizes the historical position information of target UE to calculate the positional information of Home eNodeB.

When after the historical position information getting the target UE in this HNB community, HNB can utilize the historical position information of UE to calculate the positional information of himself, the processing procedure that HNB utilizes the historical position information of UE in its community to calculate himself positional information can use many algorithms of the prior art, as can be asked the algorithm of geometric center according to multiple point, utilize the historical position information of the target UE got, calculate the positional information of HNB.In other words, in the historical position information of the target UE got, extract the locus coordinate of target UE, according to the locus coordinate Special composition geometric figure of target UE, the locus coordinate of each subscriber equipment is the coordinate value on this each summit of space geometry figure, calculate the spatial value of the geometric center of this space geometry figure, using the positional information (or claim the position coordinates of HNB) of the spatial value of this geometric center as this HNB.

Such as, be switched in this HNB community when there being N platform UE, HNB obtains out the historical position information of this N platform UE in the historical position information of the UE got by secondary satellite navigation system preserved, if the space coordinates of the historical position of this N platform UE is respectively: (X1, Y1), (X2, Y2) ... (XN, YN), then can estimate the positional information of Home eNodeB with this N number of spatial coordinate location, the position coordinate value of Home eNodeB can be: (X _hNB, Y _hNB) then,

$X_{\mathrm{HNB}}=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{x}_i;$

$Y_{\mathrm{HNB}}=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{y}_i.$

Certainly, also can calculate the positional information of HNB according to other algorithms, the embodiment of the present invention is not limited at this.

In addition, the path loss of UE can also be utilized when calculating HNB positional information, and the acquisition time of UE historical position information, set the weight of the historical position information of each target UE, according to the historical position information of each target UE weight and calculate the positional information of HNB in conjunction with corresponding algorithm.

Wherein, in 201, the mark of the target UE be switched in this community can also be obtained, that is, obtain the mark of target UE; Correspondingly, the historical position information of the target UE obtained by secondary satellite navigation system is obtained in 202, can comprise: according to the mark of target UE, in the historical position information of the subscriber equipment utilizing secondary satellite navigation system to obtain preserved, obtain and identify corresponding historical position information with target UE.

It should be noted that, the present invention also can utilize the positional information of secondary satellite navigation system Real-time Obtaining target UE, and utilizes the positional information of the target UE of Real-time Obtaining to calculate the positional information of Home eNodeB.

The indoor GNSS/GPS signal of the embodiment of the present invention residing for Home eNodeB HNB is more weak, or when HNB self does not have GNSS/GPS, HNB detects the subscriber equipment (UE be switched in HNB community, User Equipment), using the subscriber equipment that detects as target UE, then in the historical position information of the subscriber equipment got by secondary satellite navigation system preserved, obtain the historical position information corresponding with target UE, and utilize the historical position information of target UE to calculate the positional information of HNB, therefore, even if the indoor GNSS/GPS signal residing for HNB is more weak, or under HNB self does not have GNSS/GPS situation, HNB also can utilize the historical position information getting target UE by secondary satellite navigation system of preservation to calculate the positional information of HNB, thus indirect utilization GNSS/GPS achieves the accurate location to HNB.

In the present invention in an embodiment, when positioning HNB, can after HNB registration, HNB initiatively goes the positional information of the target UE obtained in its community, and completes the process utilizing target position information to calculate the positional information of HNB.In an alternative embodiment of the invention also can after HNB sends login request message to femto gateway HNB-GW, by femto gateway send carry femtocell positions upgrade instruction accept login request message to HNB, HNB receives and responds this and accepts login request message, carry out the operation of the positional information calculation HNB positional information of the target UE utilized in this HNB community, and the positional information of the HNB calculated the most at last returns to femto gateway.

See Fig. 3, it is the schematic flow sheet of the localization method of a kind of Home eNodeB of another embodiment of the present invention.

301: Home eNodeB sends login request message to femto gateway HNB-GW.

After Home eNodeB HNB starts shooting, need to send login request message to femto gateway HNB-GW.Login request message comprises mark (HNB ID, HNB Identity), wireless parameter, the positional information etc. of Home eNodeB.HNB-GW can, according to the information comprised in the login request message received, judge whether receive HNB registration request and whether respond this registration request.

Should comprise the positional information of HNB in the registration request that HNB sends, such HNB just can complete registration, and the positional information in the login request message that HNB sends can comprise IP address or grand net coverage information.

302: what reception femto gateway returned accepts login request message, accept in login request message, to carry femtocell positions information updating instruction, namely carry the instruction again obtaining Home eNodeB HNB positional information.

When HNB-GW receives the registration request of HNB, can send accept login request message to HNB, after what HNB received that HNB-GW returns accept login request message, HNB succeeds in registration.

Unlike the prior art, femtocell positions information updating instruction is carried in login request message, with the positional information indicating HNB again to obtain HNB accepting of returning of HNB-GW.In other words, in the middle of prior art, HNB-GW using the HNB positional information (IP address or grand net coverage information) that comprises in login request message as the accurate positional information of HNB, but utilize IP address or grand net coverage information not high to the positional information accuracy characterizing HNB, when HNB shift position IP address or grand net coverage constant when, the positional information of HNB can not correspondingly change, and the HNB positional information error therefore comprised in registration request is larger.In order to HNB positional information more accurately can be obtained, can carry accepting of returning of HNB-GW the request that instruction HNB obtains its positional information again in login request message.

303: Home eNodeB detects the subscriber equipment be switched in home base station cells, using the subscriber equipment that detects as target UE.

304: Home eNodeB is in the historical position information of the subscriber equipment got by secondary satellite navigation system preserved, obtain the historical position information of target UE, and using the positional information of the historical position information of this target UE as target UE, utilize the positional information of the positional information calculation Home eNodeB of target device.

The step 304 of the present embodiment is identical with the process of step 203 with the step 202 in the embodiment of the method one of the embodiment of the present invention respectively with 305, does not repeat them here.

305: the positional information of the Home eNodeB calculated is sent to femto gateway by Home eNodeB.

The positional information of HNB can be calculated according to the UE historical position information got, after determining HNB positional information, the HNB positional information calculated is sent to HNB-GW as the new location information of HNB by HNB, so that the positional information of the HNB updating location information HNB that HNB-GW utilizes this to calculate, the positional information of the HNB this calculated is as the positional information of HNB in network service and business procession.

The present embodiment is before HNB start, the historical position information of the positional information of the UE got based on A-GNSS/GPS mode as UE is preserved, after HNB start-up logging, if the indoor GNSS/GPS signal residing for HNB is more weak, or HNB self does not possess GNSS/GPS ability, and when cannot be got the positional information of HNB by GNSS/GPS, in the process of registering family base station, Home eNodeB is indicated to upgrade its positional information by femto gateway, Home eNodeB responds this instruction, obtain the historical position information being switched to subscriber equipment in this home base station cells, and utilize the UE historical position information got to calculate the positional information of HNB, the HNB positional information this calculated sends to femto gateway, so that the HNB positional information that this calculates by femto gateway carries out follow-up business process positional information used as HNB.

It should be noted that, although being switched in the multiple UE in HNB community, also may occur that the indoor GNSS/GPS signal residing for certain subscriber equipment is more weak, but relative to HNB, UE quantity is more, distribution is comparatively wide, and e.g., a part of UE may be in outdoor, such as, balcony and some open-air atmospheres; Or the indoor GNSS/GPS signal residing for most of UE is stronger, therefore in the positional information that accurately can be got these UE by A-GNSS/GPS, then HNB can obtain and be switched in HNB community and the positional information corresponding to UE accurately having obtained positional information by A-GNSS/GPS in advance.

Further, after getting UE historical position information by A-GNSS/GPS, the mode of preserving UE historical position information has multiple, corresponding with the mode of preserving UE historical position information, the concrete mode of historical position information that HNB obtains the UE be switched in this community also has multiple, when being obtained the UE supplementary mode that UE positional information adopts by A-GNSS/GPS, pseudo-range information is sent to SMLC by UE, and calculated by SMLC and get UE positional information, unlike the prior art, in the embodiment of the present invention, the positional information of the UE got can be preserved as historical position information by SMLC, see Fig. 4, show the schematic flow sheet of another embodiment of localization method of a kind of Home eNodeB of the embodiment of the present invention, in the present embodiment the UE historical position information obtained by secondary satellite navigation system is kept at Serving Mobile Location Center SMLC.

401: Home eNodeB sends login request message to femto gateway HNB-GW.

402: what Home eNodeB reception femto gateway returned accepts login request message, accept in login request message, to carry femtocell positions information updating instruction.

The operation of step 401 and step 402 in actual applications with the similar process of the embodiment of the method two of the embodiment of the present invention, do not repeat them here.

403: Home eNodeB detects all UE be switched in HNB community, using the UE that detects as target UE.

When detecting the UE switched in this HNB community, the mark of the UE be switched in this HNB community can be obtained.

404: the request of the historical position information obtaining target UE is sent to Serving Mobile Location Center SMLC, so that SMLC returns the historical position information of target UE by Home eNodeB.

Before HNB start-up logging, in SMLC, save the historical position information of UE.When HNB to send to SMLC after the historical position information obtaining UE in its community, SMLC can inquire about the local historical position information preserved, and the historical position information of subscriber equipment in Jiang Gai HNB community returns to HNB.

Further, UE mark can be comprised in the request of historical position information obtaining UE, so that SMLC is according to UE mark, in the UE historical position information preserved, inquiry identifies corresponding historical position information with UE, and returns to Home eNodeB by identifying corresponding historical position information with UE.

Due in moment to time of HNB start-up logging of UE positional information of preserving in SMLC, the position of UE may change, differ not too large to make the positional information of historical position information and the current UE reality of preserving in SMLC, HNB can set the effective time of historical position information, and obtains in the historical position of target UE the historical position information be in effective time.When SMLC receives the request of the historical position information of the acquisition UE that HNB sends, search local preserve and the historical position information of UE in Wei Gai HNB community, and verify whether the moment that the UE historical position information found is preserved exceeds this effective time to the time interval of current time, if do not exceeded, then return the historical position information found; When the historical position information of certain UE of HNB acquisition request is not within effective time, then return empty position information for this UE, SMLC, or failed message is to HNB, and the historical position information of other UE equipment is in the term of validity, then can returns to HNB.

It should be noted that, when HNB needs to obtain UE historical position information to SMLC, first need the request of the UE historical position information obtained in HNB community first to send to HNB-GW, then with HNB-GW by this request forward to SMLC.

405: Home eNodeB receives the historical position information that SMLC returns, and the historical position information utilizing SMLC to return calculates the positional information of HNB.

After SMLC returns historical position information, HNB can utilize the history that returns to calculate the positional information of self for information.
