Abstract
The invention provides a method for transmitting terminal position information. When a user device initiates switching, historical position information of the user device can be transmitted to a target base station by a source base station; the target base station can use the historical position information to analyze SON (Self-Organized Network) optimization scenes, such as coverage optimization and mobility optimization. The invention also provides a system for transmitting the terminal position information. The invention solves the problem that during terminal switching, the target base station is stopped by a positioning process and can not obtain the terminal position information.
Description
Technical field
The present invention relates to radio honeycomb communication system, more particularly, is that Long Term Evolution (LTE) and Long Term Evolution strengthen in (LTE-A) mobile communication system the method and system that terminal positional information transmits.
Background technology
LTE (Long Term Evolution) network is formed the network flattening by E-UTRAN (Evolved UTRAN) base station eNB (Evolved NodeB, the base station of evolution) and evolution packet switching center EPC (Evolved PacketCore).Wherein E-UTRAN comprises the set of the eNB that is connected by the S1 interface with EPC, can connect by X2 interface between the eNB.S1, X2 are logic interfacing.An EPC can manage one or more eNB, and an eNB also can be controlled by a plurality of EPC, and an eNB can manage one or more sub-districts.There is Operational Management System (OAM) in the network architecture simultaneously, can operates and manage one or more network element.The LTE-A system is by the LTE system evolved, and the network architecture is consistent with LTE.
Operator is in order to reduce operation cost and maintenance cost on the one hand, and setting up and run a network needs a lot of work, such as planning, configuration, optimization, calculating, adjustment, test, guard against false, minimizing failure, self-recovery.The user need simplify the use flow process on the other hand, and such as Home NodeB (base station from home) equipment, the user buys promptly wish it is a PnP device back home, and one powers on can obtain configuration operation automatically.The trend of next generation mobile networks must be self-configuring, self-optimizing, self adaptation, and human factor is more and more littler to the influence of network, has therefore proposed the self-organizing network notion.Self-organizing network comprises self-configuring and self-optimizing two aspects.In self-optimizing, comprise coverage optimization, mobility optimization, wherein relate to the detection that covers leak in the coverage optimization and cover inadequate detection, mobility optimization then needs the various handover event information that take place in the current area are collected and analyzed, and location information of terminals played an important role to the analysis of above optimization scene when wherein incident took place.
At present, widely used mobile positioning technique has three kinds in 3G network: based on network cell identification (CELL-ID) location technology, OTDOA (Observed Time Difference of Arrival, observation arrives the time difference) location technology and network A-GPS (Assisted GlobalPositioning System, the property of network auxiliary global positioning system) location technology of mixing with terminal.
The CELL-ID location technology
Based on network CELL-ID location technology is the simplest a kind of location technology, is applicable to all cellular networks, and need not terminal and network are made amendment, and just can provide automatic positioning service to current mobile subscriber.This technology is according to the position of determining the user for the residing cellular cell ID of portable terminal number, so its positioning accuracy depends on the size of portable terminal cellular cell radius of living in fully, kilometer do not wait from hundreds of rice to tens.Compare with other technology, this technological investment is less, and the location response time is shorter, and generally in 3s, but its precision is minimum, and error is bigger.
The OTDOA location technology
The OTDOA location technology is a kind of locate mode that is applied to 3G network.This location technology is measured the due in (TOA of the down-bound pilot frequency signal of different base station by portable terminal, Time of Arrival) realizes the location, its positioning accuracy is higher, orientation range is about 100～200m, but the dependence to time reference is stronger, and the influence that disturbed by multipath is also bigger.OTDOA location response time ratio CELL-ID is slightly long, approximately wants 10s.This technology need not terminal is made amendment and only need be revised network and can directly provide service to existing user.
The A-GPS location technology
A-GPS is the global positioning system of network assistance, and this method needs network and portable terminal can both receive GPS information, is a kind of technology that network base station information and GPS information position portable terminal that combines, and can use in 2G and 3G network.The advantage of this technology is mainly on its positioning accuracy, and in open space such as outdoor, its precision can reach 5～10m under the normal operation circumstances, can be rated as the highest a kind of location technology of present positioning accuracy.On the other hand, the supplementary of utilizing network to transmit can strengthen TTFF (Time To First Fix, primary positioning time), and its time of catching gps signal first reduces greatly, generally only need several seconds, and unlike the capture time first of GPS may need 2～3min.The A-GPS location response time is between 3～10s.
Because in present localization method, eNB is for considerations such as the network optimizations, also need to know the position of certain UE (subscriber equipment), therefore as E-SMLC (Enhanced Serving Mobile LocationCentre, the professional mobile positioning center of evolution) calculate or report the current location information that gets access to UE by UE after, E-SMLC can pass to MME (Mobility Management Entity) by location service response message, MME passes to eNB with location service response message then, and eNB is meant the serving BS that UE is current here.Yet when UE switches, LCS (LoCation Services, location service) positioning flow will stop or restart after switching is finished, and for target BS, not have method can know the detailed relatively positional information of current UE at present.
