Description
Technical field
The present invention relates to the communications field, relate in particular to the network equipment and the method that check the minimum road test configuration in a kind of wireless communication system.
Background technology
Utilize special equipment to carry out cost and the complexity of artificial drive test in order to reduce operator, third generation partnership project (3GPP, Third Generation Partnership Projects) at universal land radio access web (UTRAN, Universal Terrestrial Radio Access Network, comprise base station node B and radio network controller (RNC)) and the universal land radio access web (E-UTRAN of evolution, Evolved Universal Terrestrial Radio Access Network, comprising evolution base station eNB) version 10 (Release-10) of system begins to introduce minimum road test (MDT, Minimization of Drive Test) function.Core net (the CN that UTRAN is corresponding, Core Network) comprises host-user server (HSS, Home Subscriber Server), Mobile Switching Center Server (MSC Server, Mobile Switching Centre Server), the GPRS Support Node (SGSN of service, Serving GPRS Support Node, GPRS-General Packet Radio Service-GPRS) etc.The core net CN that E-UTRAN is corresponding comprises host-user server HSS, mobile management entity (MME, Mobile Management Entity) etc.Minimum road test functional utilization subscriber equipment (UE, User Equipment, or be called terminal) automatically collect metrical information and report to wireless access network (RAN by chain of command (Control Plane) signaling, Radio Access Network, refer to RNC for the UTRAN system, refer to eNB for the E-UTRAN system), report to Operation ﹠ Maintenance System (OAM by wireless access network again, Operation And Maintenance) entity (TCE is collected in tracking, Trace Collection Entity), be used for the network optimization, for example find and solve network coverage problem.
The MDT function is divided into based on the MDT (Management based MDT) of management with based on the MDT (Signaling based MDT) of signaling.Based on the activation of MDT of management normally (take the E-UTRAN system as example, below all with) OAM (Operation and Maintenance or claim network management system) sends the tracking that comprises the MDT configuration and activates message (Trace session activation) to eNB, eNB selects suitable UE in the zone of this message specifies (Area), and described MDT configuration information is sent to the UE that chooses.To send the tracking that comprises the MDT configuration by OAM to activate message (Trace session activation) and measure to activate the MDT that specifies UE to HS S (Home Subscriber Server) based on the activation of the MDT of signaling, HSS sends to MME with the MDT configuration information of described UE, MME sends to eNB with the MDT configuration information of this UE, and eNB the most at last MDT configuration information sends to UE.MDT based on signaling uses IMSI International Mobile Subscriber Identity (IMSI usually, International Mobile Subscriber Identity) or international mobile station device identification (IMEI, International Mobile Station Equipment Identity) specifies certain UE, or add that area information is with the selection of restriction UE.Based on track reference (Trace Reference) information that comprises in the MDT that manages and the MDT activation message based on signaling from OAM, comprising public land mobile network (Public Land Mobile Network, PLMN) information, by Mobile Country Code MCC (Mobile country code, MCC) and Mobile Network Code (Mobile Network code, MNC) form.
The MDT function is operated in Idle state and is operated in connected state according to it and can be divided into two kinds of mode of operations, is specially " record minimum road test (Logged MDT) " and " immediately minimum road test (immediate MDT) ".The record minimum road test refers to that UE controls idle condition at Radio Resource and (refers to the RRC_IDLE state for the E-UTRAN system; Also comprise cell _ paging channel state (CELL_PCH) and UTRAN Acceditation Area _ paging channel state (URA_PCH) for the UTRAN system).When the condition that configures satisfies, collect and the storage correlation measurement information reports when being used for receiving wireless access network (RAN) order request in the future, after wireless access network (RAN) is received described data, gather or directly be transmitted to TCE.Minimum road test refers to that UE (refers to the RRC_CONNECTED state for the E-UTRAN system at Radio Resource control connection state immediately; Refer to CELL _ DCH status (CELL_DCH) for the UTRAN system) time collect correlation measurement information and when report condition is satisfied in report active upload to wireless access network (RAN), after wireless access network (RAN) receives report, gather or directly report is passed to TCE.
In actual networking, network is shared so that operators again can be to part flexible management separately when communication network is built in cooperation.Thereby greatly shorten the networking cycle, and decrease total operating cost (TCO).Simultaneously, network is shared can promote most optimum distribution of resources, avoids overlapping construction, and realizes maintaining and increaseing the value of assets.Network is shared is just becoming very important problem in the networking.Network is shared multiple implementation method, shares comprising Access Network, refers to that a plurality of operators have a Radio Access Network at shared region, and core net and service network are independent separately, see Fig. 1.A plurality of core network operators of share of access network have separately independently mobile network sign and operator's sign.The user can preserve and manage a cover in core net and be used for being equal under residential quarter selection, cell reselection, the switching EPLMN tabulation (Equivalent PLMN list) information in signatory, this information can be changed, and national code in the IMSI of UE (MCC) PLMN consistent with region code (MNC) then is called the HPLMN (Home PLMN) of this UE.Be equal to HPLMN tabulation (Equivalent HPLMN list is called again EHPLMN list) and refer to a plurality of HPLMN codes of storing among the USIM, the HPLMN that the PLMN code in this tabulation is derived in can substitute I MSI when PLMN selects.This tabulation may also comprise the HPLMN code of deriving among the IMSI, if EHPLMN tabulation does not comprise HPLMN among the IMSI when PLMN selects, the EHPLMN in this tabulation should be considered to access PLMN (Visited PLMN).Base station in the E-UTRAN system is eNB, and eNB can learn the shared network information (Shared Network) of terminal (UE), is specially the peer-to-peer network information list (EPLMN list) that can learn terminal; The base station is RNC in the UTRAN system, and RNC also can learn the shared network information (shared Network) of terminal (UE), is specially selection (mandate) PLMN (selected PLMN) that can learn terminal.
In the prior art, the PLMN that the base station can be supported can be a plurality of, the base station is in the configuration messages of the immediately minimum road test (immediately MDT) that receives core net or directly obtain from webmaster, whether this base station of PLMN in the Trace reference message that checks in this request message is supported, if this base station is supported, eNB just can send immediately that MDT configures to relevant UE in the prior art, but in this case, although this PLMN is supported in the base station, but the PLMN of the current registration of UE (being the PLMN of UE current service) often is not the PLMN in the Trace reference message, thereby causes the immediately failure of MDT.
In the prior art, minimum road test is not considered the situation that network is shared yet immediately, share in the situation at network, the base station is in the configuration messages of the immediately minimum road test that receives core net or directly obtain from webmaster, when if the PLMN in the Trace reference message in the described request message is different with the PLMN of the current registration of UE, be to carry out MDT's immediately under the prior art.Yet in fact, the immediately MDT under reciprocity PLMN carries out the network optimization for operator certain benefit is arranged.
Therefore in the prior art, minimum road test exists the not adaptive situation of PLMN to need to solve immediately, and simultaneously, under the shared network condition, can't carrying out immediately under peer-to-peer network, the problem of MDT also needs to solve.
Summary of the invention
