- the UE location information described herein includes: geographic location information (e.g., a certain house number information of a certain street), or latitude and longitude information, and the like.
- the user equipment acquires the location information of the cell from the base station of the cell in which the UE is located, and sends the location information of the cell to the Serving Radio Network Controller (SRNC).
- SRNC Serving Radio Network Controller
- the location information of the cell includes: geographic location information of the cell, and the like.
- the cell here is a home base station HNB cell that is not undetermined location information, but refers to a base station cell in which the UE is located before the HNB is powered on. That is to say, since the HNB is not yet powered on and is not registered, there is no UE handover or reselection into the HNB base station cell.
- the serving radio network controller SRNC invokes resources of the Serving Mobile Location Centre (SMLC) corresponding to the UE according to the location information of the cell, and acquires satellite information (ie, GPS auxiliary information) available to the cell, and The acquired satellite information is returned to the UE.
- SMLC Serving Mobile Location Centre

- the ancillary data information can be: 1) auxiliary data used for measurement, such as reference time, available satellite list, satellite signal Doppler shift, code phase, etc.; 2) auxiliary data providing positioning estimation average calculation, such as satellite ephemeris, Reference position, clock correction, etc.
- the UE searches for the currently available GNSS/GPS satellite according to the satellite information, and performs pseudorange measurement of the satellite by using the available GNSS/GPS satellite to obtain pseudorange information, and uses the pseudorange information to calculate the location information of the UE.
- pseudorange measurement refers to the correlation between the measurement station (here, UE) and the satellite when the GPS is used for navigation and positioning, and the pseudo-random code transmitted by the satellite and the receiver replica code are used. Since the distance measured by the pseudorange contains a distance due to a clock error and an atmospheric refraction delay, the distance information obtained by the pseudorange measurement may be referred to as pseudorange information.

- the embodiment of the present invention saves the acquired UE location information.
- the manner in which the location information of the UE is saved may be multiple, and may be: After acquiring the location information of the UE in a manner that is assisted by the UE, the SMLC saves the location information of the acquired UE as the historical location information of the UE. In other words, before the UE is handed over to the HNB cell, the location information of the UE may be acquired by the UE, and the location information of the UE is saved by the SMLC as the historical location information of the UE.
- the location information of the UE changes, only the location information of the last acquired UE can be saved in the SMLC.
- the location information of a user equipment UE1 is saved in the SMLC.
- Locationl After the location of the user equipment UE1 is changed, the location information of the UE1 is re-acquired by the A-GNSS/GPS as location2, and the SMLC saves the location information of the UE1 as: location2.
- the UE location information in the set time may be stored, that is, only the location information of the UE in the set time is saved as the historical location information. For example, only the location information of the UE within 10 seconds before the current time is saved.
- the UE obtains the UE location information, and may also send the pseudorange information to the SRNC after the UE obtains the pseudorange information, and the SRNC calculates the location information of the UE.
- the serving radio network controller SRNC saves the calculated location information of the UE. That is, the SRNC saves the calculated location information of the UE as historical location information of the UE. Similar to the manner in which the SMLC stores the historical location information of the UE, for a certain UE, the SRNC may save only the last location information of the UE, and may also save the location information of the UE within a predetermined time.
- the UE may also save its location information.
- the network side (the network side may be an SRNC) sends a message for saving the location information of the UE to the UE device, when the UE passes the A described above.
- the network side sends a message for saving the location information of the UE to the UE device, when the UE passes the A described above.
- the UE obtains its own location information based on the UE, the UE saves the acquired UE location information, and the saved UE location information is used as the historical location information of the UE. Similar to the use of the SMLC to store the UE location information, the UE may only save the last acquired UE location information; of course, the UE may also save the UE location information within the set time.
- the location information of the user equipment may be obtained by other manners to obtain the location information of the UE, and the obtained location information of the user equipment is used as the historical location information of the user equipment.
- the saving is performed to calculate the location information of the home base station by using the location information of the user equipment.
- the embodiment of the present invention acquires the location information of the user equipment by using the auxiliary satellite positioning system, and saves the location information of the user equipment as the historical location information of the user equipment.
- the home base station HNB itself does not have the GNSS/GPS capability, or the HNB is located, HNB when the indoor environment is poor
- the location information of the HNB can be calculated by using the historical location information of the user equipment in the cell.
- FIG. 2 it is a schematic flowchart of a method for locating a home base station according to another embodiment of the present invention.
- the home base station detects the handover to the user equipment in the home base station cell, and uses the detected user equipment as the target user equipment.

That is to say, the historical location information of the saved UE includes the historical location information of the multiple UEs, but the UE corresponding to the saved historical location information of the UE is switched to the HNB area, so the query needs to be switched to the HNB.
- the historical location information of the saved UE is the location information of the UE acquired before the HNB is powered on.

At this time, when the HNB location information is calculated by using the saved historical location information of the UE acquired by the auxiliary satellite positioning system, the obtained data may be inaccurate.
- the HNB When the HNB obtains the historical location information of the UE in the HNB cell, the historical location information of the target user equipment may be queried in the saved historical location information of the user equipment acquired by the auxiliary satellite positioning system, and The historical location information of the queried obtains the historical location information within the valid time. In other words, even if a UE has recently switched to the HNB cell, the HNB does not acquire the UE because the saved time history of the UE is longer than the current time of the set historical location information.

Therefore, the HNB needs to query the historical location information of the UE1, the UE2, and the UE3 in the pre-stored user equipment, and after querying the historical location information of the UE1, the UE2, and the UE3, determine the historical location information of the saved UE1, UE2, and UE3.
- the set historical position valid time is 5 seconds
- the time when the historical location information of UE1 is saved is 2011-4-12, 09:24:20
- the UE2 history is saved.
- the time of the location information is 2011-4-12, 09:24:18
- the time at which the historical location information of the UE3 is saved is 2011-4-12, 09:24:15
- the HNB acquires the UE calendar switched to the HNB cell.
- the time (current time) of the location information is 2011-4-12, 09:24:21. Therefore, the saved historical location information of UE3 is not within the valid time of the set historical location information, and the historical location of the UE acquired by the final HNB.
- the historical location information of UE1 and UE2 should be included in the information.
- the location information of the user equipment is saved as the historical location information of the user equipment, and the specific saved location may be the historical location information of the user equipment saved as described above.
- the location information of the user equipment acquired by the auxiliary satellite positioning system may be used as historical location information and stored in the center of the service mobile location. Of course, it may also be saved in the wireless network control center, or the user equipment may save its own history. Location information, of course, there are other ways, not here - enumeration.

本申请要求于 2011 年 06 月 21 日提交中国专利局、 申请号为 201110167884.6、 发明名称为"一种家庭基站的定位方法、 定位信息更新方 法和系统"的中国专利申请的优先权, 其全部内容通过引用结合在本申请 中。
技术领域 本发明涉及移动通信技术领域, 更具体的说是涉及一种家庭基站的定 位方法、 定位信息更新方法和系统。 背景技术 家庭基站(HNB, Home NodeB ) 又称为 Femto, 是一种发射功率低、 覆盖范围小、 主要面向家庭客户或者中小企业应用的基站设备。 家庭基站 一般设置在室内, 作为蜂窝网在室内的补充, 为用户提供高质量的语音以 及高速的数据业务。
家庭基站开机后向家庭基站网关 ( HNB-GW, Home NodeB Gateway ) 发送注册请求消息进行注册, HNG-GW接收 HNB的请求并向 HNB发送接受 注册请求消息后, HNB注册成功, HNB-GW便可以向 HNB提供相应的业务。 在 HNB向 HNB-GW发送的注册请求消息中应包含 HNB ID以及 HNB位置信 息等, 其中, HNB的位置信息可以为以下三种:
1 ) HNB检测到的宏网覆盖信息, 如周围小区的位置信息等;
2 ) IP地址;
3 )地理位置信息, 如通过 GPS或 GNSS获取到的位置信息。
其中, 宏网覆盖信息和 IP地址都是根据 HNB所在位置的固网或者宏网 网点位置来估算 HNB的位置信息。 由于宏网覆盖的小区范围较大, 用 IP地 址或宏网覆盖信息表征 HNB位置信息一般只能精确到百米范围内, 得到的 HNB位置信息不够精确。 当 HNB移动位置而 IP地址或宏网网点不发生改变 的情况下, HNB的位置信息无法更新, 此时, 利用 IP地址或宏网覆盖信息 表征 HNB位置信息误差较大。
通过 GPS或 GNSS系统获取地理位置信息, 对于室外等空旷地区,得 到的地理位置信息精确度较高, 一般精度可达 10米左右。 但 HNB的应用 场景一般为室内, 而在室内可能会因为 GNSS/GPS信号质量较差不能精确 获取到 HNB的位置信息, 甚至不能获取到 HNB的位置信息。 因此, 比较 精确的获取到 HNB的位置信息是本领域技术人员需要解决的技术问题。 发明内容

其中, 小区的位置信息包括: 小区的地理位置信息等。 此处的小区是 并不是未确定位置信息的家庭基站 HNB小区, 而是指在该 HNB开机前, UE所处在的基站小区。 也就是说, 由于 HNB 目前还未开机, 没有进行注 册, 也就没有 UE切换或重选到该 HNB基站小区内。
102: 服务无线网络控制器 SRNC根据该小区的位置信息, 调用 UE对 应的服务移动位置中心 (SMLC, Serving Mobile Location Centre ) 的资源, 获取该小区可用的卫星信息(即 GPS辅助信息),并将获取到的卫星信息返 回给 UE。
SMLC 查询的卫星信息可以包括: 卫星的频段、 方位、 仰角等信息。 卫星信息也可以为网络侧对获取的卫星信息进行处理后的辅助数据信息,

103: UE根据该卫星信息查找当前可用的 GNSS/GPS卫星, 并利用可 用的 GNSS/GPS 卫星进行卫星的伪距测量, 得到伪距信息, 利用该伪距信 息计算得到 UE的位置信息。
其中, 伪距测量是指用全球定位系统进行导航和定位时, 用卫星发播 的伪随机码与接收机复制码的相关技术, 测定测量站(此处为 UE )与卫星 之间的距离。 由于伪距测量出的距离中含有由于时钟误差和大气折射延迟 的距离, 因此利用伪距测量得到的距离信息可以称为伪距信息。
104: UE将其计算得到的 UE位置信息上报给网络侧。
其中, 网络侧可以为: 无线网络控制器 SRNC。 当然网络侧也可以为其 他网络设备。 UE将 UE位置信息发送到网络侧, 以便网络侧能获取到 UE 的位置信息。
需要说明的是, 利用 A-GNSS/GPS获取 UE位置信息的方式还可以为: UE辅助方式获取的 UE位置信息, 即, 通过 UE完成伪距测量后, UE将测 量的伪距信息等数据发送给服务无线网络控制器 SRNC,由 SRNC或 SMLC 利用伪距信息等数据计算出 UE的位置信息。
与现有技术不同, 本发明实施例在通过以上所述的 A-GNSS/GPS系统 获取到 UE的位置信息后, 会保存获取到的 UE位置信息。 保存 UE位置信 息的方式可以有多种, 可以为: 当通过 UE辅助的方式获取到 UE位置信息 后, SMLC将获取的 UE的位置信息作为 UE的历史位置信息进行保存。 换 言之, 在 UE切换到该 HNB小区前, 可以通过 UE辅助的方式获取到 UE 的位置信息,并由 SMLC将 UE位置信息作为 UE的历史位置信息进行保存。 由于 UE的位置信息会发生改变, SMLC 中可以仅保存最后一次获取到的 UE 的位置信息。 例如, SMLC 中保存某用户设备 UE1 的位置信息为
locationl , 当该用户设备 UE1的位置发生改变后, 通过 A-GNSS/GPS重新 获取到该 UE1的位置信息为 location2,则 SMLC则将 UE1位置信息保存为: location2。进一步的, SMLC中还可以保存设定时间内的 UE位置信息, 即, 仅将设定时间内的 UE的位置信息作为历史位置信息进行保存。如,仅保存 当前时刻之前 10秒内的 UE的位置信息。
基于 UE辅助方式获取 UE位置信息, 还可以为当 UE获取到伪距信息 后, 将伪距信息发送给 SRNC, 由 SRNC计算出 UE的位置信息。 与现有技 术不同, 本发明实施例中, 服务无线网络控制器 SRNC会保存其计算出的 UE的位置信息。 也就是说, SRNC将计算出的 UE的位置信息作为 UE的 历史位置信息进行保存。 与 SMLC保存 UE的历史位置信息的方式相似, 针对某一 UE, SRNC可以仅保存该 UE的最后一次的位置信息, 也可以保 存预定时间内的 UE的位置信息。
当然, 还可以通过 UE来保存其位置信息, 当 UE进入无线网络后, 网 络侧(该网络侧可以为 SRNC )向该 UE设备发送保存该 UE位置信息的消 息,当 UE通过以上所述的 A-GNSS/GPS方法中基于 UE方式获取到自身的 位置信息时, UE会保存其获取到的 UE位置信息, 该保存的 UE位置信息 即作为 UE的历史位置信息。 与利用 SMLC保存 UE位置信息类似, UE可 以仅保存其最后一次获取到的 UE位置信息; 当然, UE也可以保存设定时 间内的 UE位置信息。
当然, 本发明实施例在家庭基站开机前, 还可以通过其他方式获取到 用户设备的位置信息的方式来获取 UE的位置信息,并将获取到的用户设备 的位置信息作为用户设备的历史位置信息进行保存, 以便后续利用用户设 备的位置信息计算家庭基站的位置信息。
本发明实施例通过辅助卫星定位系统获取用户设备的位置信息, 并将 用户设备的位置信息作为用户设备的历史位置信息进行保存, 当家庭基站 HNB本身不具备 GNSS/GPS能力, 或 HNB所处的室内环境较差时, HNB
可以利用切换到其小区内的用户设备的历史位置信息来计算 HNB的位置信 息,参见图 2,为本发明另一实施例的一种家庭基站的定位方法流程示意图。
201: 家庭基站检测切换到家庭基站小区内的用户设备, 将检测到的用 户设备作为目标用户设备。
本领域的技术人员可知, 当家庭基站 HNB注册成功后, 会陆续有多个 UE切换或重选到该 HNB小区内。 当有 UE切换到该 HNB小区内时, 该 HNB可以检测到切换到其小区内的所有的用户设备 UE,以及 UE的相关信 息, 如, UE的标识等信息, 然后将切换到该 HNB小区内的用户设备作为 目标用户设备。
202: 家庭基站在保存的通过辅助卫星定位系统获取到的用户设备的历 史位置信息中, 获取目标用户设备的历史位置信息。
在确定了该 HNB小区内的目标用户设备后, HNB可以获取该目标用 户设备的历史位置信息, 该目标用户设备的历史位置信息为预先利用辅助 卫星定位系统获取到的该目标用户设备的位置信息。
在家庭基站开机前为了能利用切换到该 HNB小区内的 UE的位置信息 计算出 HNB的位置信息, 需要在保存的 UE的历史位置信息中, 查询出切 换到该 HNB小区内的 UE的历史位置信息, 即查询出目标用户设备的历史 位置信息。 也就是说, 保存的 UE的历史位置信息中, 包含 4艮多 UE的历史 位置信息, 但并不是保存的 UE历史位置信息对应的 UE都切换到该 HNB 小区内, 因此需要查询切换到该 HNB小区内的目标用户设备的历史位置信 息。 其中, UE的历史位置信息是相对于当前时刻而言的, 在保存的 UE的 历史位置信息是在 HNB开机之前获取的 UE的位置信息, 当 HNB开机之 后 UE的位置信息可能会发生一些改变。 为了使利用切换到 HNB小区内的 UE历史位置信息计算得到的 HNB 的位置信息更加准确, HNB 可以设定 UE历史位置信息的有效时间, 即,保存 UE历史位置信息的时刻距离 HNB 获取 UE的历史位置信息的时刻在设定时间长度范围内,则认为 UE历史位
置信息处于有效时间内。 如, 可以设定 UE的历史位置信息的有效时间为 3 秒, 也可以根据实际需要设定有效时间的长度。
设定 UE历史位置信息的有效时间的原因为:如果保存 UE的历史位置 信息的时刻距离当前时刻的时间较长, 例如大于等于某个预设时间, UE的 位置信息可能会发生较大的改变, 此时利用保存的通过辅助卫星定位系统 获取到的 UE的历史位置信息计算 HNB位置信息时, 得到的数据可能会不 准确。
在 HNB获取切换到该 HNB小区内的 UE的历史位置信息时, 可以为: 在保存的通过辅助卫星定位系统获取到的用户设备的历史位置信息中, 查 询目标用户设备的历史位置信息, 并在查询到的历史位置信息中获取处于 有效时间内的历史位置信息。 换言之, 即使某 UE目前已切换到该 HNB小 区内,但由于保存的该 UE历史位置信息时刻距离当前时刻的时间长度超出 设定的历史位置信息的有效时间, HNB也不会获取出该 UE的历史位置信 例如, 保存的用户设备的历史位置信息中, 保存有用户设备 UE1、 用 户设备 UE2、 用户设备 UE3和用户设备 UE4 , 而切换到 HNB小区内的用 户设备仅为: UE1、 UE2和 UE3, 因此 HNB需要在预先保存的用户设备中 查询出 UE1、 UE2和 UE3的历史位置信息, 并在查询出 UE1、 UE2和 UE3 的历史位置信息之后, 判断保存的 UE1、 UE2和 UE3的历史位置信息是否 都处于设定的历史位置信息有效时间内, 如,设定的历史位置有效时间为 5 秒, 保存 UE1的历史位置信息的时刻为 2011-4-12, 09:24:20, 保存 UE2历 史位置信息的时刻为 2011-4-12, 09:24:18, 保存 UE3历史位置信息的时刻 为 2011-4-12, 09:24:15 , 而 HNB获取切换到该 HNB小区内的 UE历史位 置信息的时刻 (当前时刻) 为 2011-4-12, 09:24:21 , 因此, 保存的 UE3的 历史位置信息并不在设定的历史位置信息的有效时间内, 最终 HNB获取的 UE历史位置信息中应包括 UE1和 UE2的历史位置信息。
其中, 通过辅助卫星定位系统获取到用户设备位置信息后, 将用户设 备的位置信息作为用户设备的历史位置信息进行保存, 具体的保存的位置 可以为以上所描述的保存用户设备的历史位置信息的方式, 如可以将通过 辅助卫星定位系统获取到的用户设备的位置信息作为历史位置信息并保存 在服务移动位置中心, 当然, 还可以保存在无线网络控制中心, 或由用户 设备来保存自己的历史位置信息, 当然还可以有其他方式, 在此不——列 举。
203: 家庭基站利用目标用户设备的历史位置信息计算家庭基站的位置 信息。
当获取到该 HNB小区内的目标用户设备的历史位置信息后, HNB可 以利用 UE的历史位置信息计算其自身的位置信息,ΗΝΒ利用其小区内 UE 的历史位置信息计算其自身位置信息的处理过程可以运用现有技术中的多 种算法, 如可以根据多个点求几何中心的算法, 利用获取到的目标用户设 备的历史位置信息, 计算出 ΗΝΒ的位置信息。 换言之, 在获取到的目标用 户设备的历史位置信息中, 提取出目标用户设备的空间位置坐标, 根据目 标用户设备的空间位置坐标构成空间几何图形, 每个用户设备的空间位置 坐标为该空间几何图形各个顶点的坐标值, 计算该空间几何图形的几何中 心的空间坐标值, 将该几何中心的空间坐标值作为该 ΗΝΒ的位置信息(或 称 ΗΝΒ的位置坐标)。
例如, 当有 Ν台 UE切换到该 ΗΝΒ小区内, ΗΝΒ在保存的通过辅助 卫星定位系统获取到的 UE的历史位置信息中获取出这 Ν台 UE的历史位置 信息, 设这 Ν 台 UE 的历史位置的空间坐标分别为: (XI , Yl )、 ( Χ2, Υ2 ) ……(ΧΝ, ΥΝ ), 则可以用这 Ν个空间坐标位置估算出家庭基站的位 置信息, 家庭基站的位置坐标值可以为: ( ΧΗΝΒ , ΥΗΝΒ )贝
N
XHNB = ,
当然, 也可以根据其他算法来计算得到 HNB的位置信息, 本发明实施 例在此并不加以限制。
另外, 在计算 HNB位置信息时还可以利用 UE的路损, 以及 UE历史 位置信息的获取时间, 设定各个目标用户设备的历史位置信息的权重, 依 据各个目标用户设备的历史位置信息的权重并结合相应的算法计算 HNB的 位置信息。
其中, 201中,还可以获取切换到该小区内的目标用户设备的标识,即, 获取目标用户设备的标识; 与此对应, 202中获取通过辅助卫星定位系统得 到的目标用户设备的历史位置信息, 可以包括: 依据目标用户设备的标识, 在保存的利用辅助卫星定位系统得到的用户设备的历史位置信息中, 获取 与目标用户设备标识对应的历史位置信息。
需要说明的是, 本发明也可以利用辅助卫星定位系统实时获取目标用 户设备的位置信息, 并利用实时获取的目标用户设备的位置信息来计算家 庭基站的位置信息。
本发明实施例在家庭基站 HNB所处的室内 GNSS/GPS信号较弱,或者 HNB自身不具有 GNSS/GPS的情况下, HNB检测切换到 HNB小区内的用 户设备 ( UE , User Equipment ) , 将检测到的用户设备作为目标用户设备, 然后在保存的通过辅助卫星定位系统获取到的用户设备的历史位置信息 中, 获取与目标用户设备对应的历史位置信息, 并利用目标用户设备的历 史位置信息计算出 ΗΝΒ 的位置信息, 因此, 即使在 ΗΝΒ 所处的室内 GNSS/GPS信号较弱, 或者 HNB 自身不具有 GNSS/GPS情况下, HNB也 可以利用保存的通过辅助卫星定位系统获取到目标用户设备的历史位置信 息来计算 HNB的位置信息, 从而间接利用 GNSS/GPS实现了对 HNB的精
确定位。 本发明上一实施例中, 在对 HNB进行定位时, 可以在 HNB注册后, HNB主动去获取其小区内的目标用户设备的位置信息, 并完成利用目标位 置信息计算 HNB的位置信息的过程。在本发明另一实施例中也可以在 HNB 向家庭基站网关 HNB-GW发送注册请求消息后, 由家庭基站网关发送携带 有家庭基站位置更新指示的接受注册请求消息给 HNB, HNB接收并响应该 接受注册请求消息,进行利用该 HNB小区内的目标用户设备的位置信息计 算 HNB位置信息的操作, 并最终将计算得到的 HNB的位置信息返回给家 庭基站网关。
参见图 3,为本发明另一实施例的一种家庭基站的定位方法的流程示意 图。
301: 家庭基站发送注册请求消息到家庭基站网关 HNB-GW。
家庭基站 HNB开机后, 需要向家庭基站网关 HNB-GW发送注册请求 消息。 注册请求消息中包括家庭基站的标识(HNB ID, HNB Identity )、 无 线参数、 位置信息等。 HNB-GW会根据接收到的注册请求消息中包含的信 息, 判断是否接收 HNB注册请求以及是否响应该注册请求。
HNB发送的注册请求中应包含 HNB的位置信息, 这样 HNB才能完成 注册, HNB发送的注册请求消息中的位置信息可以包括 IP地址或宏网覆盖 信息。
302: 接收家庭基站网关返回的接受注册请求消息, 接受注册请求消息 中携带有家庭基站位置信息更新指示, 即携带有重新获取家庭基站 HNB位 置信息的指示。
当 HNB-GW接收到 HNB的注册请求时,会向 HNB发送接受注册请求 消息, HNB接收到 HNB-GW返回的接受注册请求消息后, HNB注册成功。
与现有技术不同,在 HNB-GW返回的接受注册请求消息中携带家庭基
站位置信息更新指示, 以指示 HNB重新获取 HNB的位置信息。 换言之, 在现有技术当中, HNB-GW将注册请求消息中包含的 HNB位置信息(IP 地址或宏网覆盖信息)作为 HNB精确的位置信息, 但是利用 IP地址或者 是宏网覆盖信息来表征 HNB 的位置信息精确度不高, 当 HNB移动位置而 IP地址或宏网覆盖范围不变的情况下, HNB的位置信息不会相应改变, 因 此注册请求中包含的 HNB位置信息误差较大。 为了能获取更精准的 HNB 位置信息, 在 HNB-GW返回的接受注册请求消息中会携带指示 HNB重新 获取其位置信息的请求。
303: 家庭基站检测切换到家庭基站小区内的用户设备, 将检测到的 用户设备作为目标用户设备。
304: 家庭基站在保存的通过辅助卫星定位系统获取到的用户设备的 历史位置信息中, 获取目标用户设备的历史位置信息, 并将该目标用户设 备的历史位置信息作为目标用户设备的位置信息, 利用目标设备的位置信 息计算家庭基站的位置信息。
本实施例的步骤 304和 305分别与本发明实施例的方法实施例一中的 步骤 202和步骤 203的过程相同, 在此不再赘述。
305: 家庭基站将计算得到的家庭基站的位置信息发送给家庭基站网 关。
根据获取到的 UE历史位置信息可以计算出 HNB的位置信息, 确定了 HNB位置信息后, HNB将计算得到的 HNB位置信息作为 HNB的新位置 信息发送给 HNB-GW, 以便 HNB-GW利用该计算出的 HNB位置信息更新 HNB的位置信息, 将该计算出的 HNB的位置信息作为网络通信以及业务 处理过程中 HNB的位置信息。
本实施例在 HNB开机前,将基于 A-GNSS/GPS方式获取到的 UE的位 置信息作为 UE的历史位置信息进行保存, 在 HNB开机注册后, 如果由于 HNB所处的室内 GNSS/GPS信号较弱, 或 HNB 自身不具备 GNSS/GPS能
力, 而无法通过 GNSS/GPS获取到 HNB的位置信息的情况下,在家庭基站 注册的过程中, 由家庭基站网关指示家庭基站更新其位置信息, 家庭基站 响应该指示, 获取切换到该家庭基站小区内用户设备的历史位置信息, 并 利用获取到的 UE历史位置信息计算 HNB 的位置信息, 将该计算得到的 HNB 位置信息发送给家庭基站网关, 以便家庭基站网关将该计算得到的 HNB位置信息作为 HNB进行后续业务处理所用的位置信息。
需要说明的是, 虽然在切换到 HNB小区内的多个 UE中, 也可能会出 现某台用户设备所处的室内 GNSS/GPS信号较弱, 但是相对于 HNB来说, UE数量较多、 分布范围较广, 如, 一部分 UE可能处于室外, 例如, 阳 台、 以及一些露天环境; 或者大部分 UE所处的室内 GNSS/GPS信号较强, 因此在通过 A-GNSS/GPS能精确获取到这些 UE的位置信息,则 HNB可以 获取切换到 HNB小区内且已经预先通过 A-GNSS/GPS精确获取位置信息的 UE所对应的位置信息。
进一步的, 通过 A-GNSS/GPS获取到 UE历史位置信息后, 保存 UE 历史位置信息的方式有多种,与保存 UE历史位置信息的方式相对应, HNB 获取切换到该小区内的 UE 的历史位置信息具体方式也有多种, 当通过 A-GNSS/GPS获取 UE位置信息采用的 UE辅助方式时, UE将伪距信息发 送给 SMLC, 并由 SMLC计算出获取到 UE位置信息, 与现有技术不同, 本发明实施例中, SMLC会将获取到的 UE的位置信息作为历史位置信息进 行保存, 参见图 4, 示出了本发明实施例一种家庭基站的定位方法另一实施 例的流程示意图,在本实施例中将通过辅助卫星定位系统获取的 UE历史位 置信息保存在服务移动位置中心 SMLC。
401: 家庭基站发送注册请求消息到家庭基站网关 HNB-GW。
402: 家庭基站接收家庭基站网关返回的接受注册请求消息, 接受注册 请求消息中携带有家庭基站位置信息更新指示。
步骤 401和步骤 402的操作在实际应用中与本发明实施例的方法实施
例二的过程相似, 在此不再赞述。
403: 家庭基站检测切换到 HNB小区内的所有 UE, 将检测到的 UE作 为目标用户设备。
在检测切换该 HNB小区内的 UE时, 可以获取切换到该 HNB小区内 的 UE的标识。
404: 家庭基站将获取目标用户设备的历史位置信息的请求发送给服务 移动位置中心 SMLC, 以便 SMLC返回目标用户设备的历史位置信息。
在 HNB开机注册前, SMLC中已经保存了 UE的历史位置信息。当 HNB 向 SMLC发送获取其小区内 UE的历史位置信息后, SMLC会查询本地保 存的历史位置信息, 并将该 HNB小区内的用户设备的历史位置信息返回给 HNB。
进一步的, 在获取 UE的历史位置信息的请求中可以包含 UE标识, 以 便 SMLC依据 UE标识,在保存的 UE历史位置信息中查询与 UE标识对应 的历史位置信息, 并将与 UE标识对应的历史位置信息返回给家庭基站。
由于在 SMLC中保存的 UE位置信息的时刻到 HNB开机注册的时间 内, UE的位置可能发生变化, 为了使 SMLC中保存的历史位置信息和当前 UE 实际的位置信息相差不会太大, HNB 可以设定历史位置信息的有效时 间, 并获取目标用户设备的历史位置中处于有效时间内的历史位置信息。 当 SMLC接收到 HNB发送的获取 UE的历史位置信息的请求时,查找本地 保存的且为该 HNB 小区内的 UE的历史位置信息, 并验证查找到的 UE历 史位置信息保存的时刻到当前时刻的时间间隔是否超出该有效时间, 如果 未超出, 则返回查找到的历史位置信息; 当 HNB请求获取的某 UE的历史 位置信息不在有效时间内, 则针对该 UE, SMLC返回空位置信息, 或者失 败消息给 HNB, 而其他 UE设备的历史位置信息处于有效期内, 则会返回 给 HNB。
需要说明的是, 当 HNB需要向 SMLC获取 UE历史位置信息时, 首先
需要将获取 HNB小区内的 UE历史位置信息的请求先发送给 HNB-GW,再 用 HNB-GW将该请求转发给 SMLC。
405: 家庭基站接收 SMLC返回的历史位置信息, 并利用 SMLC返回 的历史位置信息计算 HNB的位置信息。
当 SMLC返回历史位置信息后, HNB可以利用返回的历史为信息计算 出自身的位置信息。
406: 家庭基站将计算得到的 HNB位置信息发送给家庭基站网关。 基于 UE辅助方式在服务无线网络控制器 SRNC中计算出 UE位置信 息,服务无线网络控制器 SRNC将计算出的 UE位置信息作为 UE的历史位 置信息进行保存,当 UE切换到家庭基站 HNB小区内,UE原来所属的 SRNC 会检测到 UE从原基站小区切换到该 HNB小区内, SRNC会将保存的 UE 的历史位置信息发送给该 HNB,以便 HNB将历史位置信息作为 UE位置信 息计算 HNB的位置信息。 该过程与本实施例的方法相似, 不同之处在于, 当 HNB检测到切换到其小区内的用户设备,将检测到的用户设备作为目标 用户设备时, 目标用户设备原所属的 SRNC会将目标用户设备的历史位置 信息发送给该家庭基站, 家庭基站接收该 SRNC发送的目标用户设备的历 史位置信息。 换言之, 当 HNB检测到目标用户设备后, HNB无需向目标 用户设备原来所属的 SRNC发送获取目标用户设备位置信息的请求, 目标 用户设备原所属的 SRNC会主动将目标用户设备的历史位置信息发送给该 HNB。
需要说明的是, 用户设备原所属的 SRNC是指 UE在切换该 HNB基站 小区前, UE所属基站小区对应的 SRNC。 由于 UE切换到 HNB小区后, 该 UE所在的 HNB基站小区对应的 SRNC可能会发生改变, 因此将 UE切换 到该 HNB小区前, UE所属的 SRNC称为原所属 SRNC。
当然, 通过 A-GNSS/GPS获取的 UE历史位置信息也可以保存在 UE 中, 即采用基于 UE的方式获取到其位置信息后, UE将其自身位置信息作
为历史位置信息进行保存, HNB可以在 UE中获取其保存的历史位置信息。 参见图 5, 为本发明另一实施例的一种家庭基站的定位方法流程示意图, 本 实施例中在 UE中将 UE通过辅助卫星定位系统的 UE位置信息作为 UE的 历史位置信息进行保存。
501: 家庭基站发送注册请求消息到家庭基站网关。
502: 家庭基站接收家庭基站网关返回的接受注册请求消息, 接受注册 请求消息中携带有家庭基站位置信息更新指示。
503: 家庭基站检测切换到家庭基站小区内的所有用户设备, 将检测到 的用户设备作为目标用户设备。
504: 家庭基站向目标用户设备发送获取其历史位置信息的请求, 以便 目标用户设备将本地保存的历史位置信息上报给该家庭基站。
UE中已经保存了其自身的历史位置信息, 其中, UE保存的历史位置 信息可以为在 HNB开机前 UE最后一次获取的位置信息。 当 UE切换到该 HNB小区内, HNB会向 UE发送请求来获取 UE保存的历史位置信息, UE 接到请求后, 会将保存的历史位置信息上报给 HNB, 从而使 HNB获取到 切换到其小区内的 UE的历史位置信息。
与上一实施例类似,在 HNB向目标用户设备发送获取其历史位置信息 的请求时, 可以在该请求中包含历史位置信息的有效时间, 当目标用户设 备接收到该请求后, 验证自身保存的历史位置信息是否仍处于有效时间内, 如果是, 则将其保存的历史位置信息上报给 HNB; 否则, 目标用户设备将 返回空位置信息给 HNB, 或者目标用户设备返回失败消息给 HNB。
需要说明的是, 切换到 HNB小区内的 UE的数量一般会有多个, 因此 HNB会向切换到其小区内的所有 UE均发送获取历史位置信息信息的请求, 以便该小区内 UE将自身保存的历史位置信息返回给 HNB。
505: 家庭基站接收目标用户设备返回的 UE的历史位置信息, 并利用 返回的历史位置信息计算家庭基站自身的位置信息。
当小区内的目标用户设备将自身保存的 UE历史位置信息返回给 HNB 时, HNB会接收目标用户设备返回的历史位置信息, 由于返回的 UE历史 位置信息的精度较高, 利用返回的 UE历史位置信息计算出的 HNB位置信 息也具有较高的精度。
506: 家庭基站将计算得到的家庭基站的位置信息发送给家庭基站网 关。 当 HNB将其计算得到的 HNB位置信息作为新位置信息发送给家庭基 站网关后,家庭基站网关会利用接收到新位置信息的更新 HNB的位置信息, 参见图 6,为本发明一种家庭基站的定位信息更新方法的一个实施例的流程 示意图。
601: 家庭基站网关 HNB-GW接收 HNB发送的注册请求消息。
当 HNB发送注册请求消息时, HNB-GW会接收 HNB发送的注册请求 消息,并对该注册请求消息进行 3 证, HNB-GW验证通过后会接受该注册 请求。 其中, 该接收注册请求消息包括 HNB的第一位置信息, HNB的第 一位置信息可以包括 IP地址或宏网覆盖信息, HNB注册时注册请求消息中 必须包含 HNB的位置信息, 否则会出现 HNB注册失败等问题。
602: 家庭基站网关响应 HNB的注册请求, 发送接受注册请求消息给 HNB, 该接受注册请求消息中携带有家庭基站位置信息更新指示, 即携带 有在预定时间内获取 HNB的新位置信息指示。
与现有技术不同,在 HNB-GW发送的接受注册请求中会携带有家庭基 站位置信息更新指示, 以便 HNB获取其新位置信息, 并上报给 HNB-GW。
603: 当家庭基站返回其新位置信息时, 家庭基站网关接收家庭基站返 回的新位置信息, 并利用该返回的新位置信息更新家庭基站的位置信息, 新位置信息为家庭基站利用切换到其小区内的目标用户设备的历史位置信 息计算出的家庭基站的位置信息; 目标用户设备的历史位置信息为保存的
通过辅助卫星定位系统获取到的用户设备的历史位置信息中, 与目标用户 设备对应的历史位置信息。
由于切换到 HNB小区内的 UE的位置信息是通过 A-GNSS/GPS获取到 的,精确度较高,将该 UE位置信息作为 UE的历史位置信息进行保存, HNB 可以利用切换到其小区内的目标用户设备的历史位置信息计算出 HNB的位 置信息, 并将计算的 HNB 位置信息作为新位置信息发送给 HNB-GW, HNB-GW接收到该新位置信息后,可以更新原 HNB的位置信息,将该 HNB 新位置信息作为 HNB在网络通信以及业务处理过程中所用的位置信息。
其中, UE的历史位置信息可以是保存在服务移动位置中心 SMLC或无 线网络控制器 SRNC中, 也可以由用户设备保存其历史位置信息。 在实际应用中, 家庭基站网关会在发送给 HNB的重新获取 HNB位置 信息的请求中, 包含重新获取 HNB位置信息的时间, 以防止 HNB获取其 位置时间过长, 影响 HNB的其他业务操作, 参见图 7, 为本发明一种家庭 基站的定位方法另一实施例的流程示意图, 本实施例以通过 A-GNSS/GPS 中 UE辅助方式获取到的 UE历史位置信息, 且将 UE的历史位置信息保存 在 SMLC为例进行说明。
701: 家庭基站网关接收 HNB发送的注册请求消息:该接收注册请求消 息包括 HNB的第一位置信息, HNB的第一位置信息可以包括 IP地址或宏 网覆盖信息;
702: 家庭基站网关响应 HNB的注册请求, 发送接受注册请求消息给 HNB, 该接受注册请求消息中携带有在预定时间内获取家庭基站的新位置 信息的指示;
其中,预定时间可由 HNB-GW通过设置定时器参数来实现设定预定时 间, 具体的可以在接受注册请求中包括设定定时器参数信息, 以便 HNB接 收到该接受注册请求消息时, HNB和 HNB-GW同时开始计时。 HNB接收
到 HNB-GW的接收注册请求消息后, HNB注册成功, HNB响应该接受注 册请求, 开始计时。 当接收注册请求中包含定时器参数时, 开始计时为: HNB依据接受注册请求中的定时器参数, 开启定时器来设定定时时间, 当 定时器计时结束时, HNB停止获取 HNB新位置信息的过程。
703: 家庭基站网关接收 HNB发送的获取该 HNB小区内 UE的历史位 置信息的请求, 并将该请求转发给 SMLC。
704: 家庭基站网关接收 SMLC返回的 UE历史位置信息, 并将该返回 的 UE历史位置信息转发给 HNB , 以便 HNB利用返回的 UE历史位置信息 计算其位置信息, 得到 HNB的新位置信息。
其中, 该 HNB的新位置信息为 HNB利用切换到该 HNB小区内的 UE 历史位置信息计算得到的 HNB位置信息。
705:家庭基站网关判断 HNB在预定时间内是否返回 HNB的新位置信 息; 如果是, 则进入 706; 否则进入 707;
706: 家庭基站网关利用 HNB的新位置信息更新 HNB的位置信息。
707: 家庭基站网关将 HNB的第一位置信息确定为 HNB的位置信息。 需要说明的是, 当通过 UE保存其通过 A-GNSS/GPS获取到的历史位 置信息时, 家庭基站的定位方法与该实施例的过程基本相似, 不同之处在 于 HNB可以将获取 HNB小区内 UE的历史位置信息的请求直接发送给 UE, 无需经过 HNB-GW。 因此, 在通过 UE保存其通过 A-GNSS/GPS获取到的 历史位置信息情况下, 在进行 HNB的定位时, 不需要包含步骤 703和步骤 704的操作。
本发明实施例主要是以陆地无线接入 UTRAN 系统为例进行的介绍, 但本发明实施例也可以应用到其他无线通信系统中, 例如 WIMAX系统、 LTE系统等。
通过以上的方法实施例的描述, 所属领域的技术人员可以清楚地了解 到本发明可借助软件加必需的通用硬件平台的方式来实现, 当然也可以通
过硬件, 但很多情况下前者是更佳的实施方式。 基于这样的理解, 本发明 式体现出来, 该计算机软件产品存储在一个存储介质中, 包括若干指令用 以使得一台计算机设备(可以是个人计算机, 服务器, 或者网络设备等) 括: 只读存储器(ROM )、 随机存取存储器(RAM )、 磁碟或者光盘等各种 可以存储程序代码的介质。 与本发明实施例的方法相对应, 参见图 8, 本发明实施例还提供了一种 家庭基站的定位系统, 所述家庭基站的定位系统可以是家庭基站, 也可以 是家庭基站的一部分, 甚至可以是独立于所述家庭基站之外的装置, 该家 庭基站的定位系统包括: 检测单元 803,设备位置获取单元 804和基站位置 计算单元 805。
检测单元 803, 用于检测切换到家庭基站小区内的用户设备, 将检测到 的用户设备作为目标用户设备;
当 HNB注册成功后, HNB便可以通过检测单元来检测切换到其小区 内的 UE。
设备位置获取单元 804,用于在保存的通过辅助卫星定位系统获取到的 用户设备的历史位置信息中, 获取目标用户设备的历史位置信息;
需要说明的是, 当通过辅助卫星定位系统获取到的用户设备的位置信 息后, 将获取到的用户设备位置信息作为用户设备的历史位置信息进行保 存,根据前述的基于辅助卫星定位系统获取 UE的位置信息的方式不同,保 存 UE历史位置信息的位置也可以有多种,可以将基于辅助卫星定位系统获 取到的用户设备的位置信息作为用户设备的历史位置信息保存在服务移动 位置中心 SMLC ,也可以保存在无线网络控制器 SRNC , 当然还可以由用户 设备将基于辅助卫星定位系统计算出的位置信息作为自身的历史位置信息
进行保存。
基站位置计算单元 805,用于利用获取到的目标用户设备的历史位置信 息计算家庭基站的位置信息。
需要说明的是, 本发明实施例在对 HNB进行定位时, 可以在 HNB注 册后, HNB主动去获取其小区内的目标用户设备的位置信息, 并完成利用 目标位置信息计算 HNB的位置信息的过程。
当然, 在 HNB的定位过程, 也可以在 HNB向家庭基站网关 HNB-GW 发送注册请求消息后, 由家庭基站网关发送携带有家庭基站位置更新指示 的接受注册请求消息给 HNB , HNB接收并响应该接受注册请求消息, 进行 利用该 HNB小区内的目标用户设备的位置信息计算 HNB位置信息的操作, 并最终将计算得到的 HNB的位置信息返回给家庭基站网关。 对应的, 本实 施例的系统还包括: 注册请求单元 801 , 响应接收单元 802和基站位置上报 单元 806。
注册请求单元 801 , 用于发送注册请求消息到家庭基站网关。
其中, 注册请求消息中包括家庭基站网关的标识 ( HNB ID , HNB Identity ), 无线参数、 位置信息等。 HNB 发送的注册请求消息中的位置信 息可以包括 IP地址或宏网覆盖信息, 也就是说为了家庭基站 HNB注册成 功, HNB开机后将获取到的 IP地址或宏网覆盖信息作为其位置信息发送给 家庭基站网关 HNB-GW。
响应接收单元 802, 用于接收家庭基站网关返回的接受注册请求消息, 接受注册请求消息中携带有家庭基站位置信息更新指示, 也就是说携带有 重新获取家庭基站位置信息的指示。
