Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

In the embodiment of the invention, before Home eNodeB HNB start, can obtain the positional information of user equipment (UE), and the positional information of UE is preserved as the historical position information of UE through the secondary satellite navigation system.Utilizing the secondary satellite navigation system to obtain UE positional information (promptly getting access to the positional information of UE through the A-GNSS/GPS method) can comprise based on UE mode and UE supplementary mode; Referring to Fig. 1, for obtain the flow chart of UE positional information among the A-GNSS/GPS based on the UE mode.

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

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

Wherein, the positional information of sub-district comprises: the geographical location information of sub-district etc.The sub-district here is not to be not confirm the Home eNodeB HNB sub-district of positional information, and is meant before this HNB start the base station cell that UE is positioned.That is to say, also just do not have UE switching or gravity treatment in this HNB base station cell because HNB also not start is not at present registered.

102: service wireless network controller SRNC is according to the positional information of this sub-district; Call the corresponding Serving Mobile Location Center (SMLC of UE; Serving Mobile Location Centre) resource; Obtain the satellite information (being the GPS supplementary) that to use this sub-district, and the satellite information that gets access to is returned to UE.

The satellite information of SMLC inquiry can comprise: information such as the frequency range of satellite, orientation, the elevation angle.Satellite information also can be the auxiliary data information of network side after the satellite information that obtains is handled, auxiliary data information can for: 1) measure the auxiliary data of using, like the reference time, usable satellite tabulation, satellite-signal Doppler shift, code phase etc.; 2) auxiliary data of location estimation average computation is provided, like 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 pseudorange information, utilizes this pseudorange information calculations to obtain the positional information of UE.

Wherein, pseudo range measurement is meant with global positioning system and navigates and when locating, with the pseudo noise code of satellite broadcast and the correlation technique of receiver replica code, measure the distance between measuring station (being UE) and the satellite here.Because contain the distance owing to clocking error and atmospheric refraction delay in the distance that pseudo range measurement goes out, the range information that therefore utilizes pseudo range measurement to obtain can be called pseudorange information.

104:UE reports network side with the UE positional information that it calculates.

Wherein, network side can be radio network controller SRNC.Certainly network side also can be other network equipments.UE sends to network side with the UE positional information, so that network side can get access to the positional information of UE.

Need to prove; The mode of utilizing A-GNSS/GPS to obtain the UE positional information can also be UE positional information that the UE supplementary mode obtains; Promptly; After accomplishing pseudo range measurement through UE, UE sends to service wireless network controller SRNC with the data of measuring such as pseudorange information, is utilized data computation such as pseudorange information to go out the positional information of UE by SRNC or SMLC.

Different with prior art, the embodiment of the invention can be preserved the UE positional information that gets access to after getting access to the positional information of UE through above-described A-GNSS/GPS system.The mode of preserving the UE positional information can have multiple, can for: after getting access to the UE positional information through the auxiliary mode of UE, SMLC preserves the positional information of the UE that obtains as the historical position information of UE.In other words, before UE switches to this HNB sub-district, can get access to the positional information of UE, and the UE positional information preserved as the historical position information of UE by SMLC through the auxiliary mode of UE.Because the positional information of UE can change, and can only preserve the positional information of the UE that gets access to for the last time among the SMLC.For example; The positional information of preserving certain user equipment (UE) 1 among the SMLC is location1; After the position of this user equipment (UE) 1 changed, the positional information that gets access to this UE1 through A-GNSS/GPS again was location2, and then SMLC then saves as the UE1 positional information: location2.Further, can also preserve the UE positional information in the setting-up time among the SMLC, that is, only the positional information of the UE in the setting-up time preserved as historical position information.As, the positional information of only preserving the UE in 10 seconds before the current time.

Obtain the UE positional information based on the UE supplementary mode, can also pseudorange information be sent to SRNC, calculate the positional information of UE by SRNC for after getting access to pseudorange information as UE.Different with prior art, in the embodiment of the invention, service wireless network controller SRNC can preserve the positional information of its UE that calculates.That is to say that SRNC preserves the positional information of the UE that calculates as the historical position information of UE.The mode of historical position information of preserving UE with SMLC is similar, and to a certain UE, SRNC can only preserve the last positional information of this UE, also can preserve the positional information of the UE in the scheduled time.

Certainly; Can also preserve its positional information through UE; After UE got into wireless network, network side (this network side can be SRNC) sent the message of preserving this UE positional information to this UE equipment, when UE gets access to the positional information of self based on the UE mode in through above-described A-GNSS/GPS method; UE can preserve its UE positional information that gets access to, and the UE positional information of this preservation is promptly as the historical position information of UE.SMLC preservation UE positional information is similar with utilizing, and UE can only preserve its UE positional information that gets access to for the last time; Certainly, UE also can preserve the UE positional information in the setting-up time.

Certainly; The embodiment of the invention is before the Home eNodeB start; Can also obtain the positional information of UE through the mode that other modes get access to the positional information of subscriber equipment; And the positional information of the subscriber equipment that gets access to preserved as the historical position information of subscriber equipment, so that the positional information of the positional information calculation Home eNodeB of later use subscriber equipment.

The embodiment of the invention is obtained the positional information of subscriber equipment through the secondary satellite navigation system; And the positional information of subscriber equipment preserved as the historical position information of subscriber equipment; When the base station HNB of family itself does not possess the GNSS/GPS ability; Or the residing indoor environment of HNB is when relatively poor; HNB can utilize the historical position information of the subscriber equipment that switches in its sub-district to calculate the positional information of HNB, referring to Fig. 2, 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 switch in the home base station cells, with detected subscriber equipment as target UE.

Those skilled in the art can know after the base station HNB of family succeeds in registration, a plurality of UE switchings or gravity treatment can be arranged successively in this HNB sub-district.In the time of in UE switches to this HNB sub-district; This HNB can detect all user equipment (UE)s that switch in its sub-district, and the relevant information of UE, as; Information such as the sign of UE will switch to subscriber equipment in this HNB sub-district then as target UE.

202: Home eNodeB obtains the historical position information of target UE in the historical position information of passing through the subscriber equipment that the secondary satellite navigation system gets access to of preserving.

Behind the target UE in having confirmed this HNB sub-district; 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 of utilizing the secondary satellite navigation system in advance and getting access to.

Before Home eNodeB start in order to utilize the positional information calculation that switches to the UE in this HNB sub-district to go out the positional information of HNB; Need be in the historical position information of the UE that preserves; Inquire the historical position information that switches to the UE in this HNB sub-district, promptly inquire the historical position information of target UE.That is to say; In the historical position information of the UE that preserves; Comprise the historical position information of a lot of UE, but be not that the corresponding UE of UE historical position information that preserves switches in this HNB sub-district, therefore need inquiry to switch to the historical position information of the target UE in this HNB sub-district.Wherein, the historical position information of UE is the positional information of the UE that before the HNB start, obtains in the historical position information of the UE that preserves for current time, and some changes may take place the positional information of UE after the HNB start.Utilize the positional information switch to the HNB that the UE historical position information calculations in the HNB sub-district obtains more accurate in order to make; HNB can set the effective time of UE historical position information; Promptly; The moment distance H NB that preserves UE historical position information obtain UE historical position information the time be engraved in the setting-up time length range, think that then UE historical position information was in effective time.As, be 3 seconds the effective time that can set the historical position information of UE, also can set the length of effective time according to actual needs.

Set UE historical position information effective time former because: if it is longer apart from the time of current time to preserve moment of historical position information of UE; For example more than or equal to certain Preset Time; Bigger change may take place in the positional information of UE; Utilize to preserve this moment when passing through the historical position information calculations HNB positional information of the UE that the secondary satellite navigation system gets access to, and the data that obtain may be inaccurate.

When HNB obtains the historical position information that switches to the UE in this HNB sub-district; Can for: in the historical position information of passing through the subscriber equipment that the secondary satellite navigation system gets access to of preserving; The historical position information of query aim subscriber equipment, and in the historical position information that inquires, obtain the historical position information that is in effective time.In other words; Even certain UE has switched in this HNB sub-district at present; But because this UE historical position information of preserving exceeds the effective time of the historical position information of setting constantly apart from the time span of current time, HNB can not obtain out the historical position information of this UE yet.

For example, in the historical position information of the subscriber equipment of preservation, preserve user equipment (UE) 1, user equipment (UE) 2, user equipment (UE) 3 and user equipment (UE) 4; And the subscriber equipment that switches in the HNB sub-district is merely: UE1, UE2 and UE3, so HNB need inquire the historical position information of UE1, UE2 and UE3 in the subscriber equipment of preserving in advance, and after inquiring the historical position information of UE1, UE2 and UE3; The historical position information whether the historical position information of UE1, UE2 and the UE3 that judge to preserve all is in setting is in effective time, as historical position effective time of, setting be 5 seconds; The moment of preserving the historical position information of UE1 is 2011-4-12,09:24:20, and 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 HNB to obtain the moment (current time) of the UE historical position information that switches to this HNB sub-district in be 2011-4-12; 09:24:21; Therefore, the historical position information of the UE3 of preservation should comprise the historical position information of UE1 and UE2 in the UE historical position information that final HNB obtains not in the effective time of the historical position information of setting.

Wherein, After getting access to position information of user equipment through the secondary satellite navigation system, the positional information of subscriber equipment is preserved as the historical position information of subscriber equipment, the position of concrete preservation can be the mode of the historical position information of preservation subscriber equipment described above; As can be with the positional information of the subscriber equipment that gets access to through the secondary satellite navigation system as historical position information and be kept at Serving Mobile Location Center; Certainly, can also be kept at the wireless network control center, or preserve the historical position information of oneself by subscriber equipment; Certainly other modes can also be arranged, not enumerate one by one at this.

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

After the historical position information of the target UE in getting access to this HNB sub-district; HNB can utilize himself the positional information of historical position information calculations of UE; HNB utilizes the processing procedure of himself positional information of historical position information calculations of UE in its sub-district can use multiple algorithm of the prior art; As can ask the algorithm of geometric center according to a plurality of points, and utilize the historical position information of the target UE that gets access to, calculate the positional information of HNB.In other words; In the historical position information of the target UE that gets access to; Extract the locus coordinate of target UE, according to the locus coordinate formation space geometry figure of target UE, the locus coordinate of each subscriber equipment is the coordinate figure on this each summit of space geometry figure; Calculate the spatial value of the geometric center of this space geometry figure, with the spatial value of this geometric center as the positional information of this HNB (or claim HNB position coordinates).

For example, in N platform UE switched to this HNB sub-district, HNB obtained out the historical position information of this N platform UE in the historical position information of passing through the UE that the secondary satellite navigation system gets access to of preserving; If the space coordinates of the historical position of this N platform UE is respectively: (X1; Y1), (X2, Y2) ... (XN, YN); Then can go out the positional information of Home eNodeB with this N space coordinates position estimation, 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, can calculate the positional information of HNB according to other algorithms, the embodiment of the invention does not limit at this yet.

In addition; When calculating the HNB positional information, can also utilize the path loss of UE; And the acquisition time of UE historical position information; Set the weight of the historical position information of each target UE, according to the weight of the historical position information of each target UE and combine the positional information of corresponding algorithm computation HNB.

Wherein, in 201, can also obtain the sign that switches to the target UE in this sub-district, that is, obtain the sign of target UE; Corresponding therewith; Obtain the historical position information of the target UE that obtains through the secondary satellite navigation system in 202; Can comprise: according to the sign of target UE; In the historical position information of utilizing the subscriber equipment that the secondary satellite navigation system obtains of preserving, obtain and target UE sign corresponding historical positional information.

Need to prove that the present invention also can utilize the secondary satellite navigation system to obtain the positional information of target UE in real time, and utilize the positional information of the target UE obtain in real time to calculate the positional information of Home eNodeB.

The embodiment of the invention the residing indoor GNSS/GPS signal of Home eNodeB HNB a little less than; Perhaps HNB self does not have under the situation of GNSS/GPS; HNB detects and to switch to the subscriber equipment (UE, User Equipment) in the HNB sub-district, with detected subscriber equipment as target UE; Then in the historical position information of passing through the subscriber equipment that the secondary satellite navigation system gets access to of preserving; Obtain and target UE corresponding historical positional information, and utilize the historical position information calculations of target UE to go out the positional information of HNB, therefore; Even the residing indoor GNSS/GPS signal of HNB a little less than; Perhaps HNB self does not have under the GNSS/GPS situation, and HNB also can utilize the positional information that historical position information that the secondary satellite navigation system gets access to target UE is calculated HNB of passing through of preservation, thereby indirect utilization GNSS/GPS has realized the accurate location to HNB.

Among the last embodiment of the present invention, when HNB is positioned, can be after the HNB registration, HNB initiatively goes to obtain the positional information of the target UE in its sub-district, and accomplishes the process of utilizing target position information to calculate the positional information of HNB.Also can be after femto gateway HNB-GW sends login request message in another embodiment of the present invention at HNB; Send the login request message of accepting that carries femtocell positions renewal indication by femto gateway and give HNB; HNB receives and responds this and accepts login request message; Utilize the operation of the positional information calculation HNB positional information of the target UE in this HNB sub-district, and the positional information of the HNB that calculates the most at last returns to femto gateway.

Referring to Fig. 3, be the schematic flow sheet of the localization method of a kind of Home eNodeB of another embodiment of the present invention.
