Description
Technical field
The present invention relates to the mobile location service field in Radio Network System.More specifically, the location service service method and the device that relate to a kind of location information request.
Background technology
Mobile location service in the Radio Network System more and more is subjected to paying close attention to widely.The main application of mobile location service includes: the emergency calling position service that is used for user security; Follow the tracks of the location of relevant criminal activity; Individual's positioning service (for example inquiry of service industry such as traffic, lodging information); Intelligent transportation transportation location; The design of Radio Network System and resource management; Be used for the charging (determining the communication cost of some position according to calling rate) of Radio Network System.Mobile positioning technique includes the location that covers based on the sub-district, strengthen observed time difference (EOTD, Enhanced Observation Time Difference) location technology, the observable time of advent poor (OTDOA, Observed Time Difference OfArrival) location technology, the time of advent (TOA, Time Of Arrival) location technology, arrive angle (AOA, Arrival of Angle) location technology, advanced forward link triangle location (AFLT, Advanced Forward Link Trilateration), EFLT (EnhancedForward Link Trilateration), uplink time-difference of arrival (UTDOA, UpLinkTime Difference of Arrival) global positioning system (AGPS of location technology and network assistance, Assisted Global Positioning System) multiple mode such as location technology, the situation that satisfies service quality according to positioning result can be divided into the three major types location technology:
1. low precision location technology, the location technology that covers based on the sub-district for example, the current position that is in the sub-district of good location accuracy and sub-district covering and the user that is positioned is relevant usually, and the response time is fast.
2. middle precision location technology, location technologies such as EOTD, OTDOA, TOA, AOA, AFLT, EFLT, UTDOA for example, good location accuracy and wireless environment etc. are relevant usually.Response time is between the response time of low precision location technology and hi-Fix technology.
3. hi-Fix technology, for example AGPS comprises all kinds of satellite systems that GPS (Global Position System) (GNSS, Global Navigation Satellite Systems) comprises etc.Response time is the slowest, even can reach tens of seconds.
The use of different location technologies is relevant with the service quality of the user capability that is positioned, mobile network's stationkeeping ability and residing environment of the user that is positioned and Location Request.The location response time of different location technologies is also different with positioning accuracy simultaneously.So need be in conjunction with the location quality of service needed location technology in a certain position fixing process of coming together specifically to select.

Following table is done the contrast explanation to QOS information in the location request message among the QOS information in the existing location request message and the present invention.
When initiating the positioning service request, mobile network's positioning service center and the interface existing standard between the external position service agent have defined three class time delay types: make an immediate response, low time delay and time delay tolerable, other interface definition the time delay type of two class response times: low time delay and time delay tolerable.The present invention increases the maximum requirement of DELAY RESPONSE time for wherein low time delay and time delay tolerable two classes.If position requests is to be initiated by the external position service agent, then response time maximum requirement can be by service agent according to the type of service setting; If position requests is to initiate automatically by the mobile network is inner, then location-server oneself is provided with the response time maximum, more particularly, after location service is initiated, response time maximum ground location information request is set can be to be the processing net element in each stage in the position requests processing procedure, for example, initiating type for Client, can be each stage network element that client, Gateway Mobile Location Center (GMLC), SGSN or MSC etc. transmit position request information; Can be after being provided with by client, directly to transmit this parameter to follow-up network element, also can be after being provided with by client, when follow-up network element transmits maximum response time, deduct the intermediate conveyor new maximum response time that conduct is set oneself after the time.
For example in the WCDMA network of 3GPP definition, when location service agency (LCS Client) request positions a certain UE, according to the location service type of request, set low time delay, low DELAY RESPONSE time maximum, then the location request message that has QOS information is passed to GMLC.GMLC can select not have low peaked location request message of DELAY RESPONSE time to network element transmission thereafter, after message sends, set peaked timer of response time, be timed to and do not receive positioning result message, then stop current position fixing process, to LCS Client indication location failure; GMLC also can select to have low peaked location request message of DELAY RESPONSE time to network element transmission thereafter, wait for positioning result message afterwards, obtained the response time maximum if do the network element of localization method selection, then can determine localization method more flexibly, even when the failure of location, clearly continue to select the location to report that still failure to the network element on it, finishes the location then.
For low time delay type, specify the maximum require time delay, make position determining entity have something to base in position fixing process.
For the time delay tolerable, can specify the time delay maximum, make have something to base in the position determining entity position fixing process, avoid positioning time long, or the too short phenomenon that does not satisfy required precision.Certainly for the time delay maximum, also can be set to infinity, the processing of position determining entity at this moment can not limit the response time satisfying under the prerequisite of positioning accuracy.

In the step S314 process for Fig. 3, accompanying drawing 4 has been described concrete processing procedure.
Accompanying drawing 4 has been described four kinds of location scenes, and step S404 is first kind of successful scene in AGPS location; Step S406 and step S408 have described second kind of AGPS location failure and have waited for the scene of proceeding the AGPS location; Step S410 has described the third AGPS location failure and has selected other successful scenes in localization method location; Step S412 and step S408 have described the 4th kind of AGPS location failure and have selected other localization method also to fail, and continue with the successful scene in straight way location, AGPS location.Bottom elaborates to this.
Step S402: do the location information request that the entity of locational decision is received, adopt the AGPS location technology to position;
Step S404: selection AGPS locatees a kind of processing mode successfully, if locate successfully, then obtains to satisfy the locating result information of QOS;
Step S406: select the AGPS location to locate unsuccessful first;
Step S408: wait for and proceed the AGPS location, up to the positioning result that obtains to satisfy QOS, this class situation occurs in the residing position of the current user of being positioned and can not observe enough satellites can't be with the phenomenon of AGPS location, if the current network or the user that is positioned do not support precision locate mode in other, can wait for that the user is in the gps satellite information that can observe, and is met the positioning result of QOS then;
Step S410: selection AGPS gets nowhere the location location first, but precision location in the network and the user's support that is positioned, and acquisition positioning result in precision location satisfies the QOS requirement in the selection;
Step S412: the location is unsuccessful first to select the AGPS location, precision location during but the network and the user that is positioned support, the positioning accuracy of location failure of middle precision or middle precision location can not satisfy the QOS required precision in the request position information, then forwards step S404 to and handles.
Step S414: the entity or the SMLC that do locational decision send to location information request side MSC/SGSN to the positioning result that satisfies the QOS requirement, and this position fixing process finishes.
Accompanying drawing 5 and accompanying drawing 6 illustrate in the location request message that the Iu interface is received, the horizontal accuracy of QOS parameter and vertical precision definition all are less than 50 meters, the response time type of QOS parameter is low time delay, the processing procedure of Access Network side when the response time maximum is set to 5 seconds.
