Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Fig. 1 is the flow chart of the localization method based on cell ID (Cell ID) in an embodiment, and the localization method is used to position mobile device.The localization method comprises the following steps：
S110, receive the locating request message that mobile device is sent.
Mobile device can send locating request message by the api interface that operator develops to the location-server of operator.The collection of wireshark packet capturing technologies mobile device (the being referred to as user equipment (UE)) signaling that send can be used, includes the positioning message of locating request message so as to find out whether mobile device sends by wireshark bags.
S120, neighbor cell measurement instruction is sent to mobile device.
Neighbor cell measurement is instructed for controlling mobile device to carry out neighbor cell (Automatic Neighbor Relation, ANR) measure, whether meet pre-determined threshold condition across station cell (namely across station adjacent area) so that detection is adjacent with serving cell.Pre-determined threshold condition be able to can also be carried in neighbor cell measurement instruction with default setting, i.e., also include pre-determined threshold condition in neighbor cell measurement instruction.In one embodiment, detection mark in base station can also be included in locating request message.Detection mark in base station can use the IP address of location-server, can also use specific message format, for example can be represented using source port+target port+special packet length.Therefore, location-server only detects that base station detection mark just issues neighbor cell measurement instruction (ANR measurement instructions).
Mobile device carries out ANR measurements according to ANR measurement instructions.ANR measurement process specifically includes following steps：First, mobile device according to ANR measurement instructions measure neighbor cell and the Physical Cell Identifier (Physical Cell Identifier, PCI) across station adjacent area for meeting pre-determined threshold condition is reported into location-server.When have it is multiple across stand adjacent area meet pre-determined threshold condition when, can by the condition that meets it is multiple across station adjacent area Physical Cell Identifier formed list report location-server.Location-server sends cellular global identity measurement instruction after the Physical Cell Identifier list is received for the list.Wherein, for LTE wireless networks, cellular global identity is ECGI (E-UTRAN Cell Global Identifier), and for 2G and 3G wireless networks, cellular global identity is CGI (Cell Global Identifier).After cellular global identity measurement instruction is received, cellular global identity corresponding to acquisition simultaneously generates ANR measurement reports and reports location-server mobile device.
In one embodiment, timing can also be proceeded by while neighbor cell measurement instruction is sent.Therefore also include step before S130, judge ANR measurement reports whether are received in preset duration, if it is perform S130, otherwise return and perform S120, so that it is guaranteed that location-server can receive ANR measurement reports.By being set to the response time of mobile device, can avoid mobile device do not reply for a long time cause location-server wait as long for caused by the time waste, and ensure that positioning can be smoothed out.
S130, receive the neighboring cell measurement reporting that mobile device reports.
