Description
Technical field
The present invention relates to the drive test field of radio communication, more particularly to a kind of minimum drive test based on signaling
The method and system of (Minimization of Drive Test, MDT).
Background technology
In order to reduce the cost and complexity that operator carries out artificial drive test using special equipment, third generation Partnership Program
(Third Generation Partnership Projects, 3GPP) is organized in universal land radio access web
(Universal Terrestrial Radio Access Network, UTRAN) and Evolved UTRAN
The version 10 of (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) system
(Release-10) start to introduce MDT functions.UTRAN includes base station and radio network controller (RNC), its corresponding core net
(Core Network, CN) includes home subscriber server (Home Subscriber Server, HSS), mobile switching centre
Server (Mobile Switching Centre Server, MSC Server), the GPRS Support Node (Serving of service
GPRS Support Node, SGSN) etc..E-UTRAN includes evolution base station (eNB), and its corresponding core net CN includes HSS, moved
Dynamic management entity (Mobile Management Entity, MME) etc..
MDT functions are collected metrical information using user equipment (User Equipment, UE) and pass through chain of command automatically
(Control Plane) signaling, which is reported, gives wireless access network (Radio Access Network, RAN), and herein, RAN is
UTRAN, E-UTRAN etc. general designation, then by RAN report to Operation ＆ Maintenance System (Operation And Maintenance,
OAM entity (Trace Collection Entity, TCE) is collected in tracking).MDT application scenarios mainly include covering excellent
In terms of change, capacity optimization, mobility optimization, common signal channel parameter optimization.
In the prior art, MDT includes the MDT (Management based MDT) based on the management and MDT based on signaling
(Signaling based MDT), by taking E-UTRAN systems as an example, same below, the activation of the MDT based on management is usual
It is：The MDT that OAM sends messages to eNB to activate some UE is measured, and eNB selects UE according to region (Area) information received, and
MDT configuration information is sent to the UE chosen；The activation of MDT based on signaling is typically：OAM send messages to HSS with
Some UE MDT measurements are activated, the MDT configuration information of the UE is sent to MME by HSS, and MME sends out the MDT configuration information of the UE
ENB is given, most MDT configuration information is sent to UE to eNB at last.MDT based on signaling generally uses IMSI International Mobile Subscriber Identity
(International Mobile Subscriber Identity, IMSI) or international mobile station device identification
(International Mobile Station Equipment Identity, IMEI) specifies some UE, or along with area
Domain information is to limit UE selection.
MDT supports UE to carry out MDT measurements in connection (CONNECTED) state and idle (IDLE) state, in connection status
The MDT of progress is referred to as MDT (Immediate MDT) immediately, and the MDT carried out in idle condition is referred to as record MDT (Logged
MDT).Immediately MDT refer to UE connection status according to MDT configuration information carry out MDT measurements and in time by metrical information report to
RAN, then reported by RAN to TCE.Record MDT, which refers to UE, to carry out MDT measurements according to MDT configuration information in idle condition and will survey
Information storage is measured, is reported again to RAN when waiting subsequently into connection status, then reported by RAN to TCE.UE can be equipped with MDT immediately
Configuration information and record two sets of independent configuration informations of MDT configuration information, MDT configuration information is for instructing UE to carry out immediately immediately
MDT is measured to be used to instruct UE to carry out record MDT measurements and storage with report, record MDT configuration information.Two kinds of MDT configuration informations
All it is to UE when UE is in connection status by network configuration.MDT configuration information fails after more than the specified time, right
In MDT configuration information immediately, it can also be failed after UE enters idle condition.
UE state for E-UTRAN wireless heterogeneous networks (Radio Resource Control, RRC) angle,
It is divided into connection status (RRC_CONNECTED) and idle condition (RRC_IDLE)；From the EPS mobile management (EPS of core net
Mobility Management, EMM) for angle, it is divided into EMM unregistered (EMM-DEREGISTERED), EMM registered
(EMM-REGISTERED), wherein, EPS be evolution grouping system (Evolved Packet System)；From core net
For EPS Connection Management (EPS Connection Management, ECM) angle, it is divided into ECM idle (ECM-IDLE), ECM
Connect (ECM-CONNECTED).Its corresponding relation is as follows：
Therefore, UE idle condition is divided into unregistered (DEREGISTERED), registered (REGISTERED) again here
Two states, in this way, UE state is divided into three kinds：Connection status (CONNECTED), idle registered state (IDLE＆
REGISTERED), idle unregistered state (IDLE＆DEREGIS TERED).
When being restarted after situations such as UE occurs shutdown, power down, crashed, because UE MDT configuration information has been lost, because
And the MDT measurements before can not being further continued for carrying out, wherein, the MDT configuration information includes MDT configuration information and record immediately
MDT configuration information；Or, when reentering connected state after UE is idle registered state into IDLE states, due to standing for UE
I.e. MDT configuration information has been lost, therefore can not be further continued for the measurements of MDT immediately before progress, so as to cause the MDT based on signaling
Operating efficiency it is relatively low.
The content of the invention
In view of this, it is a primary object of the present invention to provide a kind of method and system of the MDT based on signaling, Neng Gouti
Rise the operating efficiency of the MDT based on signaling.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of method for minimizing drive test MDT based on signaling, methods described includes：
