According to the invention, positioning service key indicator attribute is configured to all UE (user equipment), and only the MDT of the UE conforming to the positioning service key indicator attribute is activated. The MDT process of the UE is linked with the UE positioning service activating process so as to ensure that the report of the position information is realized based on the MDT process.
Description
Technical field
The present invention relates to the communications field, be specifically related to the method and system that a kind of realization minimum road test (MDT, Minimizationof Drive Tests) activates.
Background technology
At present, using MDT, is the mode fast and effectively of the network of wireless network being carried out coverage optimization.Wireless network can excited users equipment (UE, User Equipment) MDT, make that UE can the collection network performance data and report.
The network performance data that UE reported needs corresponding with positional information, like this could be helpful to the mobile communication network optimization.For can reporting position information, UE at first need obtain the positional information of self, and the UE technology of obtaining positional information mainly contains at present:
1, cell id (CELL ID) technology
This technology relies on wireless network, and positional information is the CELL ID of UE ownership mobile base station, and positioning accuracy depends on that the mobile base station distributes and range size.
2, radio position finding radio directional bearing technology
This technology relies on wireless network, and based on the radio position finding radio directional bearing technology, UE sends radio to the location-server (generally being exactly the mobile base station) of fixed position.
3, satellite positioning tech
This technology depends on global position system, like global positioning system (GPS, Global PositioningSystem), through receiving satellite signal to calculate the position of UE.
4, wireless network secondary satellite location technology
This technology depends on global position system surely, uses the wireless telecommunications net can shorten the system initialization time, and positioning accuracy is consistent with GPS.
In sum, the UE positioning service as MDT reporting position information necessary condition is and the irrelevant stand-alone service of MDT.In order to realize the MDT reporting position information, just need solution to activate the MDT flow process of UE and the interaction problems between the activation UE positioning service flow process, but the technology of not being correlated with is at present got up the MDT flow process of UE with activation UE positioning service Connection between Processes.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method and system of the MDT of realization activation, so that the MDT flow process of UE is got up with activation UE positioning service Connection between Processes, guarantees to realize reporting of positional information based on the MDT flow process.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of method that realizes that MDT activates is provided with positioning service key index attribute to user equipment (UE), and this method also comprises: the MDT that only activates the UE that meets positioning service key index attribute.
The method that said positioning service key index attribute is set is:
In the tracking and controlling parameter of MDT tracing task, increase positioning service key index attribute.
The said UE that meets positioning service key index attribute draws through following operation:
Whether the positioning service key index of inspection UE matees with set said positioning service key index, and select the UE of check result for coupling, as the UE that meets positioning service key index attribute.
This method also comprises:
The said UE of un-activation positioning service still activates positioning service because of MDT is activated, and reports the MDT data that comprise the network performance data corresponding position information;
Perhaps, the said UE of un-activation positioning service still activates positioning service because of carrying out the capacity of equipment inquiry, and reports the MDT data that comprise the network performance data corresponding position information.
This method is applied among Evolved Packet Core EPC and/or the evolved UMTS Terrestrial radio access network E-UTRAN;
Following carrying out one of at least in the operation by the base station:
The said positioning service key index attribute that UE is set;
Said activation meets the UE of positioning service key index attribute.
A kind of realization MDT activated system, this system comprise that positioning service key index attribute maintenance unit, MDT activate decision package; Wherein,
Said positioning service key index attribute maintenance unit is used for to UE positioning service key index attribute being set;
Said MDT activates decision package, is used for only activating the MDT of the UE that meets set said positioning service key index attribute.
Said positioning service key index attribute maintenance unit when said positioning service key index attribute is set, is used for:
In the tracking and controlling parameter of MDT tracing task, increase positioning service key index attribute.
Said MDT activates decision package, is used for drawing the said UE that meets positioning service key index attribute through following operation:
Whether the positioning service key index of inspection UE matees with set said positioning service key index, and select the UE of check result for coupling, as the UE that meets positioning service key index attribute.
The said UE of un-activation positioning service still is further used for:
Activate positioning service because of MDT is activated, and report the MDT data that comprise the network performance data corresponding position information;
Perhaps, activate positioning service because of carrying out the capacity of equipment inquiry, and report the MDT data that comprise the network performance data corresponding position information.
This system is arranged in EPC and/or E-UTRAN;
Said positioning service key index attribute maintenance unit, MDT one of activate in the decision package at least, are arranged in the base station.
It is thus clear that; The inventive method and system; All can positioning service key index attribute be set to UE; And only activate the MDT of the UE that meets positioning service key index attribute, thereby can the MDT flow process of UE be got up with activation UE positioning service Connection between Processes, guarantee to realize reporting of positional information based on the MDT flow process.
