Description
Technical field
The present invention relates to the communications field, particularly, relate in particular to a kind of report method, device and terminal of measurement report.
Background technology
In the construction of Radio Network System, indoor covering has become the most important thing of networking, rational indoor covering scheme can make network system farthest bring into play its effect on the one hand, for operator creates bigger value, also can save the networking cost of operator on the other hand greatly, the high repayment of the low input of real realization.Thus, a kind of radio reception device that is called base station from home arises at the historic moment.Base station from home is deployed in private sites uses such as family, group, company or school as the dedicated resources of private user, can various high-speed radio access services be provided and preferential on the rate is provided to the user, remedy existing distributed cellular radio communication system simultaneously and cover defect of insufficient, (Universal Mobile Telecommunications System represents with HNB in UMTS) base station from home in universal mobile telecommunications system; (Long-Term Evolution represents with HeNB in LTE) at long evolving system.
The frequency resource that base station from home can use operator to reserve as base station from home specially, also can use the frequency resource identical with macro base station, sub-district under macro base station ((e) NB) covers is called macrocell, and the sub-district under base station from home covers is called the base station from home sub-district.Base station from home has three kinds of access modules at present: open mode, closed mode and mixed mode, and wherein, the base station from home of open mode allows all users to insert, and corresponding sub-district is called the base station from home sub-district (open cell) of open mode; The base station from home of closed mode only allows to insert through the user who authorizes, as users such as the kinsfolk that authorizes, members of community, these have constituted a closed user group (CSG through the user's (being called for short the Member Users) who authorizes, ClosedSubscriber Group), identify with CSG ID (CSG Identity), the user allows each closed user group id of inserting, be stored in subscriber equipment (User Equipment, abbreviate UE as) in, sub-district under the base station from home of closed mode covers is called the base station from home sub-district of closed mode, is called for short the CSG sub-district; The base station from home of mixed mode also has a closed user group, the base station from home of mixed mode is except the permission Member Users inserts, also allow non-Member Users to insert, but the Member Users enjoys the preferential assurance power of service quality, priority allocation power on the resource and the preferential right on the rate, corresponding sub-district is called the base station from home sub-district (hybrid cell) of mixed mode.
The base station from home sub-district has a Physical Cell Identifier and a global cell identity.Physical Cell Identifier is called main scrambler (Primary Scramble Code is called for short PSC) in UMTS; Be called Physical Cell Identifier (Physical Cell Identity is called for short PCI) in LTE, for explaining conveniently, PCI and PSC are referred to as Physical Cell Identifier among the present invention.The Physical Cell Identifier limited amount, totally 504 (0-503) are individual.Global cell identity is called cell ID (Cell identity) in UMTS, be called global cell identity (CellGlobal Identity is called for short CGI) in LTE, and for explaining conveniently, CGI and Cellidentity are referred to as global cell identity among the present invention.A large amount of deployment along with base station from home, two or more base station from home sub-district inevitably can occur and use the situation of identical Physical Cell Identifier, in UMTS and LTE, be referred to as PCI conflict (PCI confusion), (Public Land Mobile Network, PLMN) scope is interior unique and global cell identity is at public land mobile network.With the current macrocell that resides in of UE is example, if being arranged, two or more base station from home sub-district uses identical Physical Cell Identifier, macrocell is received behind the Physical Cell Identifier of the base station from home sub-district that UE reports can't unique definite target home base station sub-district, when PCI confusion occurring, UE must be by reading the system message of base station from home sub-district, obtain global cell identity and report network, network based global cell identity could unique definite target home base station sub-district.In addition, prior art can guarantee can not occur UE and measure the situation that identical Physical Cell Identifier is used in two base station from home sub-districts simultaneously, be that PCI confusion problem only can cause at network side and obscures, promptly network side can't be from the Physical Cell Identifier that UE reports unique definite target home base station sub-district.
The CSG sub-district only allows the Member Users to insert, therefore for satisfying travelling performance good under the connected state (or claiming performance of handoffs), UE must initially insert judgement/initial access control (Preliminary Access Check) to the CSG sub-district, it is the system message that UE need read the CSG sub-district, allow each CSG ID of inserting according to the user who preserves among CSG ID that broadcasts in the system message and the UE, judge whether UE allows to insert this CSG sub-district, and the result that initial access is judged reports network side, thereby avoided network side that UE is switched to and do not allowed the CSG sub-district inserted, after guaranteeing to introduce the CSG sub-district, UE good travelling performance under connected state, promptly under connected state, realize the initial access of CSG sub-district is judged, UE will inevitably read the system message of CSG sub-district, has effectively solved PCI confusion problem (if just in time having PCI confusion) simultaneously in this.
Hybrid cell is except the permission Member Users inserts, also allow non-Member Users to insert, for the Member Users, hybrid cell is exactly a CSG sub-district, and for non-Member Users, hybrid cell is exactly a common sub-district (normal cell), and promptly non-Member Users treats hybrid cell as macrocell.Hybrid cell allows all UE to insert, so UE do not need hybrid cell is initially inserted judgement, i.e. if there is no PCIconfusion, and UE does not need to read the system message of hybrid cell.Because in the prior art, UE does not also know whether the measured employed Physical Cell Identifier of hybrid cell is identical with the employed Physical Cell Identifier of other hybrid cell, promptly have only network side just to know whether to exist PCI confusion problem, PCI confusion (is example with the LTE system) flow process that therefore solves hybrid cell as shown in Figure 1:
Step 1-1: Serving cell sends to UE and measures configuration (being included in the RRC connection reshuffles among the signaling RRC Connection Reconfiguration);
Step 1-2:UE carries out measurement, and the PCI and the measuring amount of the hybrid sub-district of satisfying report condition are reported Serving cell;
Step 1-3: after Serving cell is received the measurement report of UE, judge that the employed PCI in this hybrid sub-district is identical with other hybrid PCI that use the sub-district;
Step 1-4: Serving cell notice UE needs the PCI of the hybrid sub-district of read system message;
Step 1-5:UE switches to target hybrid sub-district receiving system message to receiver voluntarily according to current business and scheduling situation;
After step 1-6:UE gets access to the CGI of target hybrid cell,, carry PCI and the CGI of target hybrid cell in the measurement report once more to the Serving cell reporting measurement reports.
In the above-mentioned flow process, because UE does not know whether measured hybrid cell exists PCI confusion, UE must be earlier to the network side reporting measurement reports, wait for that there is PCI confusion in the network side judgement, and after notice UE needed the PCI of hybrid sub-district of read system message, the system message that UE just begins to read target hybrid cell was obtaining its global cell identity, and then reporting measurement reports, cause measurement report to report time-delay to increase, influence user's business experience.
