Description
Technical field
The present invention relates to the minimum drive test based on management in the communications field, more particularly to a kind of wireless communication system
(MDT) configuration information delivery method and network element.
Background technology
In order to reduce the cost and complexity that operator carries out artificial drive test using special equipment, third generation Partnership Program
(3GPP, Third Generation Partnership Projects) be organized in universal land radio access web (UTRAN,
Universal Terrestrial Radio Access Network) and evolution universal land radio access web (E-
UTRAN, Evolved Universal Terrestrial Radio Access Network) system version 10
(Release-10) start to introduce and minimize drive test (MDT, Minimization of Drive Test) function.UTRAN includes
Base station (Node B) and radio network controller (RNC), its corresponding core net (CN, Core Network) include host-user
Server (HSS, Home Subscriber Server), Mobile Switching Center Server (MSC Server, Mobile
Switching Centre Server), service GPRS Support Node (SGSN, Serving GPRS Support Node,
GPRS-General Packet Radio Service- GPRSs) etc..E-UTRAN includes evolution base station
(eNB), its corresponding core net CN includes host-user server (HSS), mobile management entity (MME, Mobile
Management Entity) etc..It is logical that MDT functions collect metrical information using user equipment (UE, User Equipment) automatically
Cross chain of command (Control Plane) signaling report to wireless access network (RAN, Radio Access Network, for
UTRAN systems refer to RNC, and eNB is referred to for E-UTRAN systems), then by wireless access network report to Operation ＆ Maintenance System (OAM,
Operation And Maintenance) tracking collect entity (TCE, Trace Collection Entity).MDT's should
Mainly include that coverage optimization, capacity optimize, mobility optimizes, in terms of common signal channel parameter optimization with scene.
MDT supports the MDT (Management based MDT) based on the management and MDT based on signaling in the prior art
(Signaling based MDT).The activation of MDT based on management is typically (by taking E-UTRAN systems as an example, below
The MDT that OAM sends messages to eNB to activate some UE is measured together), 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 that OAM sends messages to HSS to swash
The MDT configuration information of the UE is sent to MME by some UE living MDT measurements, HSS, and MME sends the MDT configuration information of the UE
To eNB, most MDT configuration information is sent to UE to eNB at last.MDT based on signaling generally with IMSI International Mobile Subscriber Identity (IMSI,
International Mobile Subscriber Identity) or international mobile station device identification (IMEI,
International Mobile Station Equipment Identity) some UE is specified, or along with area information
To limit UE selection.
MDT supports UE to carry out MDT measurements in connection (CONNECTED) state and idle (IDLE) state in the prior art,
The MDT carried out in connection status is referred to as MDT (Immediate MDT) immediately, and the MDT carried out in idle condition is referred to as recording MDT
(Logged MDT).MDT refers to UE in connection status according to MDT configuration information progress MDT measurements and in time by metrical information immediately
Report to wireless access network, then reported by wireless access network to TCE.Record MDT refers to UE and matches somebody with somebody confidence according to MDT in idle condition
Breath carries out MDT measurements and stores metrical information, is reported again to wireless access network when waiting subsequently into connection status, then lead to
Wireless access network is crossed to report to TCE.UE can be equipped with MDT configuration information immediately and record two sets of independent configurations of MDT configuration information
Information, MDT configuration information is for instructing UE to carry out MDT measurements immediately and report immediately, and recording MDT configuration information is used to instruct UE
Carry out record MDT measurements and storage.Two kinds of MDT configuration informations are all to UE when UE is in connection status by network configuration.
When carrying out UE selections by eNB under the MDT (Management based MDT) based on management at present, according to
Current registration PLMN (RPLMN) information of UE and MDT PLMN (Public Land Mobile Network, public land movement
Net) it is consistent when or service PLMN (SPLMN) it is consistent with MDT PLMN when can select UE progress MDT measurements.And in reality
In networking, network share causes operators again can be to respective part flexible management while Cooperative construction communication network.From
And the networking cycle is greatly shortened, and total operating cost (TCO) is greatly lowered.Meanwhile, network share can promote money
Source optimization is configured, it is to avoid repeated construction, is realized and is maintained and increaseed the value of assets.Network share is just turning into very important in networking ask
Topic.Network share has a variety of implementation methods, shared including access network, refers to multiple operators and possesses a nothing in shared region
Line access network, core net and service network are each independent, see Fig. 1.Multiple core network operators of share of access network possess each
Independent mobile network mark and operator identifier.User can preserve and manage in core net when signing a set of for cell
Equal EPLMN lists (Equivalent PLMN list, equivalent EPLMN lists) information under selection, cell reselection, switching,
The information can be changed.For the MDT based on management, it is necessary to carry out configuration verification by eNB to select suitable UE
Carry out configuration distributing, then current single pass MDT PLMN and RPLMN/SPLMN matching cannot meet demand, so
Mode selectable UE quantity can be caused to reduce so that MDT measurements issue scope and limited to, while so that under EPLMN networks
UE loses the chance for carrying out MDT measurements, and network side can not also obtain corresponding measurement report.
Therefore, when network share, how to realize that minimum drive test configuration information issues problem and needs to be resolved,
It so could preferably meet operator MDT processing energy and expectation of the equal processing under main PLMN under multiple EPLMN.
