The IP operation network of operator is the business network of operator, and this network provides IP service by evolution system for the user;

Charging gateway is used to collect the user and shuts the ticket of generation in gateway and Packet Data Network, and is sent in the bill system;

The bill system is used for generating detailed bill according to the ticket that the rate and the charging gateway of operator's configuration are sent;

Wireless network is to be made up of evolution base station (E-UTRAN NodeB is called for short eNB), and it mainly is responsible for the transmitting-receiving of wireless signal, by air interface and terminal contact, Radio Resource, scheduling of resource, the access control of management air interface;

Terminal, the state in evolution system are divided into two kinds, and a kind of is mobility management states, and another kind is the connection management state.Mobility management states is used for monitoring terminal in the relevant information of the mobile management of network, and it has two states, login state and not registered state.Login state shows that terminal registers in evolution system, network has its contextual information, positional information etc., and terminal can be used professional by evolution system; Not registered state shows that terminal do not register in evolution system, evolution system does not have its contextual information and positional information, and terminal can not be used professional in evolution system.The connection management state is used for the terminal of login state, is used for monitoring the terminal of login state and the signaling connection status between the mobility management unit, and it has two states, " free time " and " connection "." free time " state shows does not have the Non-Access Stratum signaling to connect between terminal and the mobility management unit, can not transmit the Non-Access Stratum signaling, and terminal can not be passed through the evolution system transceive data; " connection " state shows has the Non-Access Stratum signaling to connect between terminal and the mobility management unit, can transmit the Non-Access Stratum signaling, and terminal can be passed through the evolution system transceive data.The terminal of login state, if its connection management state is an idle condition, then this terminal must be initiated the service request flow process and transfers it to connection status.

Home eNodeB (Home eNB, abbreviate HeNB as) be a kind of of evolution base station, dedicated resources as the certain user, being deployed in private sites such as family, group, company or school uses, Home eNodeB only belongs to some users to be owned, and can only be that these users and other authorized users are used.The user that the owner of Home eNodeB and owner authorize forms a group, be called internal user group (Closed Subscriber Group, be called for short CSG), these Home eNodeB all belong to the dedicated resources of internal user group, have only internal user group user could insert use.

Evolution system the inside disposing Home eNodeB also has configuration server (Configuration Server abbreviates CS as).The configuration server the inside stores all data about the internal user group, these data comprise: the device number (HeNB ID) of the Home eNodeB that all users' that the internal user group id of each internal user group (CSG Identity abbreviates CSG ID as), internal user group comprise tabulation, internal user group is all and keeper's sign thereof.Configuration server also comprises information such as the charging regulation, service quality of internal user group correspondence.Internal user group inside may also have different user types, and at this moment, configuration server also can be preserved at information such as the charging regulation of same internal user group different user types, service quality.Configuration server can be provided with separately, also can close according to operator's needs and assigned user server and establish.Configuration server and policy charging rule server have the interface of intercommunication, and the policy charging rule server can arrive relevant charging of inquiry and service quality information on the configuration server.

Each internal user group identifies at the unique sign in mobile network's (Public Land MobileNetwork abbreviates PLMN as) the inside with one, and this sign is internal user group id (CSG Identity abbreviates CSG ID as).The overlay area of internal user group is made up of the home base station cells that it had.The sub-district of Home eNodeB is internal user group sub-district.

The user may belong to a plurality of internal user groups, so the user need know the resource under which internal user group and allow its access, therefore, evolution system is that internal user group user distributes a white tabulation (allowed CSG list), and white tabulation the inside comprises the sign of the internal user group that the user is allowed to access.Have only being identified in this white tabulation of internal user group, this internal user group just allows this user's access.The resource that like this, just can guarantee the internal user group effectively has only the user of internal user group to use.Evolution system is controlled the access of user to Home eNodeB by white tabulation.

When terminal detects the wireless signal of internal user group sub-district, at first to receive this cell broadcast information, check that internal user group id in the broadcast message is in the white tabulation in the terminal or not.If do not exist, then do not select the Serving cell of this sub-district as terminal; If, just select this sub-district as Serving cell.

For the member of different internal user groups, network billing may be different, also may be different for the charging of different classes of member in the same internal user group.In addition, some guest member's terminal might allow internal user group manager obtain deduction and exemption on the telephone expenses or preferential to the use of internal user group resource in the internal user group.So, charge for internal user group membership's terminal, network need know when this terminal originating service, use be which internal user group.

In evolution system, when terminal is in idle condition, initiate business by evolution system, must initiate the service request flow process, set up the carrying of terminal to core net, be used for transport service.In the service request flow process, evolution system is all radio bearers and the S1 interface bearing between all activated bearer reconstruction terminal to base station of this terminal.

Terminal is when being in idle condition, what terminal was registered in evolution system may be a plurality of internal user groups, terminal these the registration after the internal user group under moving between cells the time, can the initiating updating of tracking area flow process, therefore, evolution system does not know that the terminal of idle condition is on earth among the sub-district of which internal user group.

Simultaneously, in the service request flow process of prior art, the base station can also send to mobility management unit together with the cell ID of this informed source when transmitting business request information, and evolvement network can charge to terminal according to this cell ID.

The client is more and more higher to the requirement of the accurate bill of telephone expenses now.Because different clients can produce different telephone expenses according to the different user classification in different internal user groups, so the client wishes to demonstrate its consumption in different internal user groups in bill.Yet,, therefore can't allow evolvement network this terminal be implemented the distinctive charging of difference internal user group so mobility management unit can not be known the internal user group of terminal from this cell ID.In addition, in existing procedure, also can't allow evolvement network know the class of subscriber of this terminal, can not carry out distinctive charging to the different members of same internal user group, just do not accomplish to allow operator use professional telephone expenses situation according to guest member's class of subscriber, deduction and exemption manager member's telephone expenses yet.
