Description
Technical field
The present invention relates to moving communicating field, during in particular to a kind of switching, approach processing method and the system of indication.
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 larger value, also can greatly save on the other hand the networking cost of operator, really realize low input high repayment.Thus, the radio reception device that one is called Home eNodeB (Home eNodeB, HeNB) arises at the historic moment.Home eNodeB is deployed in the private sites such as family, group, company or school and uses as the dedicated resources of private user, can various high-speed radio access services be provided and preferential on rate is provided to user, make up existing distributed cellular radio communication system simultaneously and cover not enough defect.
It is the reserved frequency resource of Home eNodeB specially that Home eNodeB can be used operator, also can use the frequency resource identical with macro base station, macro base station (eNB) covers Xia community and is called macrocell, and Home eNodeB covers Xia community and is called home base station cells.Home eNodeB has three kinds of access modules at present: open mode, closed mode and mixed mode, wherein, the Home eNodeB of open mode allows all user's accesses, corresponding community is called the home base station cells (open cell) of open mode, and this community and common macrocell are as broad as long, the Home eNodeB of closed mode only allows the user's access through authorizing, as the kinsfolk who authorizes, the users such as member of community, these have formed a closed user group (CSG through the user's (being called for short Member Users) who authorizes, Closed Subscriber Group), identify with CSG ID (CSGIdentity), user allows each closed user group sign of access, be stored in subscriber equipment (UserEquipment, referred to as UE) in, the Home eNodeB of closed mode covers the home base station cells that Xia community is called closed mode, be called for short CSG community, the Home eNodeB of mixed mode also has a closed user group, the Home eNodeB of mixed mode is except permission Member Users accesses, also allow non-Member Users's access, but Member Users enjoys the preferential assurance power of service quality, preferential right on priority allocation power and rate in resource, corresponding community is called the home base station cells (Hybrid Cell) of mixed mode.
CSG community only allows Member Users to access, for meeting travelling performance good under connected state, UE needs DuiCSG community to carry out initial access judgement (Preliminary Access Check), be System information block 1 (the System Information Block1 that UE need to read CSG community, SIB1), the each CSG ID that allows access according to the user who preserves in the CSG ID broadcasting in SIB1 and UE, judges whether UE allows to access GaiCSG community.In addition home base station cells has a Physical Cell Identifier (Physical Cell Identity, PCI) and one global cell identity (Cell Global Identifier, CGI), the limited amount (504) of PCI, along with a large amount of deployment of Home eNodeB, the inevitable situation that must there will be two or more home base station cells to use identical PCI, and CGI is unique in public land mobile network (Public Land Mobile Network, PLMN) scope.UE can directly obtain the PCI of home base station cells in Cell searching/measuring process, and CGI must just can obtain by reading SIB1.Take the current macrocell that resides in of UE as example, if there are two or more home base station cells, use identical PCI, macrocell is received after the PCI of the home base station cells that UE reports cannot unique definite target home base station cells, for addressing the above problem, need UE to read the SIB1 of target home base station cells, obtain CGI and reported macrocell, thus unique definite target home base station cells.Conventionally network side knows which frequency is the special frequency that is exclusively used in CSG community, and network side is also known the PCI scope (PCI Range) that mixing frequency ShangCSG community is used.
Because Home eNodeB has mobility as the equipment of plug and play, and magnanimity is disposed, generally can configuring adjacent cell relation between macrocell HeCSG community, be that UE is the information that can not obtain adjacent C SG community when macrocell is switched to CSG community, the information such as CSG ID, CGI, TAC (Tracking Area Code, tracking area coding), PLMN that UE needs real-time detection to obtain CSG community just can reach the object of switching.Simultaneously because UE authorizes CSG community to have preferential or preferential right at some, therefore UE need to be switched to suitable CSG community as soon as possible, UE need to preserve the CSG cell information of the closed mode having accessed or accessed for this reason, this part information is called footprint or fingerprint, by footprint or fingerprint, UE can initiatively and detect the contents such as the neighboring BS information, address of the PCI that authorizes CSG community, footprint or fingerprint can comprise CSG community, frequency, GaiCSG community in time.UE need to preserve the home base station cells (being Hybrid Cell) of (being member) mixed mode of the mandate having accessed or accessed, for non-member's Hybrid community, UE does not need to preserve footprint or fingerprint information.Due to plug and play and the mobility of Home eNodeB, if variation has occurred for the PCI of home base station cells or frequency, UE still needs to detect within a certain period of time and complete switching flow.
When enter footprint or fingerprint region in the UE of connection status, if network side has the ability (network side is notified UE by dedicated signaling) of switching to CSG/Hybrid community, UE informing network side joint is closely indicated (Proximity Indication), at this, approach the frequency information and access network technology (the Radio Access Technology that in indication, comprise place, CSG/Hybrid community, RAT, comprises E-UTRAN or UTRAN).Network side receives that this approaches after indication, comprising:
If network side does not configure the measurement configuration (comprising measurement clearance or compact model) of place, CSG/Hybrid community frequency, network side will configure the measurement configuration (comprising measurement clearance or compact model) of described frequency for this UE; UE is according to the neighbor cell of frequency described in new measurement allocating and measuring; If there is the community that meets report condition, UE sends measurement report to network side; Network side will be according to measurement report, specifies UE to read the system message of suitable CSG/Hybrid community; UE obtains network and specifies after the system message of CSG/Hybrid community, implements initial access control judgement (Preliminary AccessCheck), and report network side.The initial access control information (initial access control information is also referred to as handover preparation information, i.e. handover preparation information) that network side reports according to UE is implemented handover decisions.
If network side has configured the measurement configuration of place, CSG/Hybrid community frequency, network side can specify UE to read the system message of suitable CSG/Hybrid community according to measurement report; UE obtains network and specifies after the system message of CSG/Hybrid community, implements initial access control judgement (Preliminary Access Check), and report network side.The initial access control information that network side reports according to UE is implemented handover decisions.
When having reported to network side, UE approaches after indication (Proximity Indication), UE can not just detect the CSG/Hybrid community of the mandate that signal satisfies condition immediately, UE can not just be switched to the CSG/Hybrid community of mandate immediately, UE still may switch to other macrocell, after UE is switched to other macrocells and cuts, need to again report and approach indication to the community (Target cell) being newly switched to, Target cell receives that this approaches after indication, carry out respective handling, the method waste interface-free resources, and postponed UE to the switching of authorizing CSG/Hybrid community.
