Description
Technical field
The present invention relates to mobile communication technology, be meant a kind of method and system that home base station cells information is provided to subscriber equipment (UE, User Equipment) especially.
Background technology
Home eNodeB is a kind of small base station of plug and play, dedicated resources as private user is deployed in private sites uses such as family, group, company or school, Home eNodeB can provide higher service rate for the user, and reduce and use the needed expense of high rate services, remedy existing distributed cellular radio communication system simultaneously and covered not enough problem.
Universal mobile telecommunications system (UMTS, Universal Mobile Telecommunications System) in, Home eNodeB (HNB, Home NodeB) is by femto gateway (HNB GW, Home NodeBGateway) is connected with core net, as shown in Figure 1.In Long Term Evolution (LTE, the Long-Term Evolution) system, evolved Home eNodeB (HeNB, Home eNodeB) can pass through evolved home gateway (HeNB GW, Home eNodeB Gateway) is connected with core net, also can directly be connected, as shown in Figure 2 with core net.
In below describing, HNB and HeNB are referred to as Home eNodeB, HNB GW and HeNB GW are referred to as femto gateway, with Home eNodeB management system (HMS, Home NodeB ManagementSystem) and evolved Home eNodeB management system (HeMS, Home eNodeB ManagementSystem) be referred to as the Home eNodeB management system.The Home eNodeB management system is a webmaster module, therefore, does not provide its concrete logic OR physical connection among Fig. 1, Fig. 2.
The function that femto gateway is mainly carried out is: the fail safe of checking Home eNodeB; Handle Home eNodeB registration, go registration, Home eNodeB is carried out access control; Home eNodeB is carried out operation maintenance management; According to Carrier Requirements configuration and control Home eNodeB; Be responsible for the data interaction between core net and the Home eNodeB.The function that the Home eNodeB management system is mainly carried out is: Home eNodeB is carried out positional information checking (locationverification), and according to Carrier Requirements configuration and control Home eNodeB, realize the configuration management function to Home eNodeB.
When powering on, Home eNodeB need send positional information to the Home eNodeB management system, this positional information can be the grand neighboring BS information of Home eNodeB or based on the positional information of GLONASS (Global Navigation Satellite System) (GNSS, GlobalNavigational Satellite System) or the broadband connection information (being connected to the IP address of DSL as Home eNodeB) of Home eNodeB; The Home eNodeB management system verifies that to the positional information of receiving the back is the Home eNodeB configuration parameter.
The Home eNodeB management system is mainly Home eNodeB and disposes three class relevant parameters: core net level parameter, wireless access network level parameter and radio-frequency stage parameter.Wherein, core net level parameter can comprise public land mobile network (PLMN, Public Land Mobile Network) sign, lane place coding (LAC in UMTS, Location Area Code), Routing Area Code information such as (RAC, Routing Area Code); In the LTE system, can comprise PLMN sign, tracking area coding information such as (TAC, Tracking Area Code); Wireless access network level parameter comprises that global cell identity (is Cell Identity, abbreviates Cell ID as among the UMTS; Be Cell Global Identifier in the LTE system, abbreviate CGI as), information such as cell selecting reselecting parameters, Neighboring Cell List; The radio-frequency stage parameter comprises that frequency point information, Physical Cell Identifier information (are main scrambler Physical Scramble Code among the UMTS, abbreviate PSC as; Be Physical CellIdentity in the LTE system, be called for short PCI) etc.
Home eNodeB is deployed in special field such as family, company or school as the dedicated resources of private user, and some cell set that Home eNodeB covers become the overlay area of Home eNodeB.Sub-district under macro base station (NodeB or eNodeB) covers is called macrocell, and the sub-district under Home eNodeB covers is called home base station cells.
At present, Home eNodeB has three kinds of access modules: open mode, closed mode and mixed mode.Wherein, the Home eNodeB of open mode allows all users to insert, and corresponding sub-district is called the home base station cells (open cell) of open mode; The Home eNodeB of closed mode only allows to insert through the user who authorizes, as the kinsfolk who authorizes, users such as member of community, these users through authorizing, be that member user has constituted a closed user group (CSG, Closed Subscriber Group), identify by CSG ID, the Home eNodeB of different closed modes can have identical CSG ID, promptly belong to same closed user group, authorization message is stored in the Subscriber Identity Module (USIM of UE, Universal Subscriber Identity Module) in, corresponding sub-district is called the home base station cells of closed mode, is called for short the CSG sub-district; The Home eNodeB of mixed mode also has a closed user group, the Home eNodeB of mixed mode is except the permission Member Users inserts, also allow non-Member Users to insert, but the Member Users enjoys preferential assurance power, the priority allocation on the resource power of service quality and the preferential right on the rate, and corresponding sub-district is called the home base station cells (hybridcell) of mixed mode.
Along with a large amount of deployment of Home eNodeB, UE certainly will comprise the cell selecting gravity treatment of Idle state and the switching of connected state moving between home base station cells and the home base station cells or between macrocell and the home base station cells.The frequency resource that Home eNodeB can use operator to reserve for all Home eNodeB specially also can be used the frequency resource identical with macro base station.Home base station cells has a Physical Cell Identifier and a global cell identity, because the limited amount of Physical Cell Identifier, a large amount of deployment along with Home eNodeB, can occur the situation that two or more home base station cells use identical Physical Cell Identifier inevitably, and global cell identity is unique in the PLMN scope.
UE can directly obtain the Physical Cell Identifier of home base station cells in cell search process, and global cell identity must just can obtain by read system message.A large amount of deployment along with Home eNodeB, when two or more home base station cells use identical Physical Cell Identifier, in the handoff procedure under the connected state, macro base station is received behind the Physical Cell Identifier of the home base station cells that UE reports can't unique definite target home base station cells, must obtain the global cell identity of target home base station cells and report macro base station and could uniquely determine by UE, and the system message that reads the target home base station cells will certainly influence the current business of UE, increase overhead, especially for the home base station cells of the closed mode that only allows the Member Users to insert, it is the CSG sub-district.Therefore the system message that need adopt an effective measure and avoid the frequent search of UE/measurements home base station cells or read the target home base station cells, thus the power consumption of UE effectively reduced, reducing the Signalling exchange with network, reduction is to the influence of UE business.
The CSG sub-district only allows the Member Users to insert, if UE under Idle state once by manual CSG Cell searching or automatically CSG cell selecting or gravity treatment inserted certain and allow the CSG sub-district inserted, UE will store the relevant information of corresponding CSG sub-district, can comprise one or more among PLMN sign, frequency point information, PSC, Cell ID, LAC, the RAC and the information that characterizes corresponding CSG subdistrict position among the UMTS, as the neighboring BS information of CSG sub-district or the GNSS positional information of CSG sub-district; Can comprise one or more among PLMN sign, frequency point information, PCI, CGI, the TAC and the information that characterizes corresponding CSG subdistrict position among the LTE, as the neighboring BS information of CSG sub-district or the GNSS positional information of CSG sub-district.After this, UE can be by the above information of storage, just begin this CSG sub-district is searched for/measured when judging UE near a certain CSG sub-district, after UE searches for/measures this CSG sub-district once more, UE does not even need to read once more the system message of this CSG sub-district, directly use the relevant information of this CSG sub-district that UE preserved to insert (comprising the gravity treatment of Idle state and the switching of connected state) and get final product, thereby avoid frequent search/measurement home base station cells to a certain extent or read the system message of target home base station cells.Need to prove, home base station cells for mixed mode, the Member Users regards it as a CSG sub-district when carrying out behaviors such as cell selecting gravity treatment, therefore, said here CSG sub-district comprises the situation the when Member Users handles the home base station cells of mixed mode.
But, the CSG sub-district of not inserting for UE (this CSG sub-district allows UE to insert), for example, the campus, under the Home eNodeB deployment scenario such as enterprise and megastore, all Home eNodeB in same campus/enterprise/market belong to same closed user group, promptly all home base station cells have identical CSG ID, if UE is authorized to allow to insert this closed user group, then this UE is allowed to access all home base station cells in all this campus/enterprise/markets, but obviously UE can not insert all home base station cells in this campus/enterprise/market under Idle state, thereby still can't avoid UE frequently to search for/measure home base station cells or read the system message of target home base station cells.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method and system that home base station cells information is provided to subscriber equipment, make UE can obtain the CSG cell information, and then more effectively avoid UE frequently to search for/measure the CSG sub-district or read the system message of target CS G sub-district.
