Packet domain in Fig. 1 (PS) comprises service universal grouping wireless serving GPRS support node (SERVICEGPRS SUPPORT NODE, SGSN) and gateway general packet wireless service support node (GGSN).
User plane gateway in Fig. 2, Fig. 3 and Fig. 4 (SAE-GW) comprises gateway (ServingGateway, S-GW) and packet data network gateway (Packet Date Network Gateway, P-GW); Mobile model management entity (Mobility Management Entity, MME) is responsible for user's mobile management.
Need to prove, the terminal in the present invention is not distinguished UE and MS.
Closed user group (Closed Subscriber Group, CSG) is to introduce the concept that proposes after base station from home.Usually the user of one family or an enterprises forms a closed user group, and this closed user group identifies with CSG ID.The base station from home of serving for user in this closed user group has identical CSG ID.The user be by can be linked into the corresponding base station from home of a plurality of closed user group with operator is signing, such as user's office space, family etc.Therefore introduced the concept that allows closed subscriber group list.This closed subscriber group list is kept in the home subscriber data server of user's terminal and network side.
User terminal mainly utilizes closed subscriber group list to carry out the selection of wireless area, base station from home can be informed user terminal with the CSG ID under it and use pattern by the mode of broadcasting, if user terminal get find after broadcast this base station be closed use pattern and CSG ID not in the permission closed subscriber group list of self preserving, user terminal thinks that this base station from home residential quarter is not suitable for accessing and automatically selects other to be fit to the honeycomb of access so.Can avoid in this way user terminal to carry out continually access attempts, reduce the consumption of battery and interface-free resources.
When the user carried out the initialization access, the home subscriber data server of network side can send to the permission closed subscriber group list that the user contracts the mobility management unit of core net.The core network mobility administrative unit can utilize this list to carry out access control to UE.If UE is from undelegated closed mode base station from home access core net, core net can be refused such user's access so.
Home eNodeB also can be used as ordinary base station and uses, and this moment, the access module of Home eNodeB was open (OPEN) pattern.Under this pattern, Home eNodeB can be accessed by any user, and from the user of such pattern access, mobile management entity does not need the user of access is done access control yet.Same, Home eNodeB can have mixed mode, and a part of user is adopted the closed mode access, and a part of user is adopted open mode.
For the user of granted access base station from home, wish gerentocratic according to base station from home can be divided into two kinds of interim granted access and permanent granted access.The user of interim granted access just cannot access the base station from home under certain CSG ID sign again after the regular hour, even if the permanent user of the granted access right that also can wish gerentocratic according to base station from home immediately calls off a visit.
Allow at present the duration of casual user's access as user's subscription data, the home subscriber data server can be with signing data distributing to the core network mobility administrative unit in the UE access network, and the core network mobility administrative unit is preserved this information.When terminal was in connected state, if the duration of the Home eNodeB that the casual user connects is overtime, the core network mobility administrative unit can be deleted overtime CSG sign from the CSG identification list that allows user's access so.
But the operational notification that in existing scheme, network side can't be own performed is to UE, so asynchrony phenomenon has occured the permission closed subscriber group list that should operation can cause user terminal and network side.Can cause terminal can not use up-to-date permission closed subscriber group list to operate so on the one hand, the follow-up cell reselection that may make the mistake, measurement report generate, invalid access attempts and waste Radio Resource; On the other hand, the operation of network side may cause the user to be switched under a non-CSG residential quarter, the strategies such as charging between Home eNodeB and ordinary base station may be not quite similar, and the user may not wish to switch to the higher ordinary base station of rate, but UE does not also know the reason that switch this moment, also switch reasons can't be presented to the user, so the user can not determine whether will use common base station according to different situation, affect user's experience.
In prior art when the user uses urgency traffic and non-emergent business under the family expenses base stations, if the duration of the Home eNodeB that the casual user accesses is overtime, the core network mobility administrative unit can with non-emergent business deactivation, only keep urgency traffic for this user so.The user will not know current CSG residential quarter not in allowing closed subscriber group list, when the user initiates regular traffic in this CSG residential quarter, can be refused by network, affect user's experience.
