Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and system of subscriber equipment access base station from home.
Background technology
Base station from home is a kind of small-sized, lower powered base station, be deployed in the indoor place such as family and office, Main Function is to provide higher service rate to user, and reduce the expense used required for high rate services, make up the deficiency that existing distributed cellular radio communication system covers simultaneously.The advantage of base station from home is as follows: economical, convenient, low-power output, plug and play, broadband access, use single-mode terminal etc.
Base station from home can be applied in the third generation (3Generation, referred to as 3G) or Long Term Evolution (Long Term Evolution, referred to as LTE) mobile communications network.When family expenses base station applies is in 3G network, referred to as Home Node B (Home Node B, referred to as HNB); When family expenses base station applies in the lte networks time, referred to as the Node B (Home Evolved Node B, referred to as HeNB) of family expenses evolution.For the ease of managing base station from home, introduce new network element, i.e. a home base-station gateway at wireless access network.Home base-station gateway mainly performs following function: the fail safe of checking base station from home; The registration of process base station from home; Operation maintenance management is carried out to base station from home; According to Carrier Requirements configuration and control base station from home; Be responsible for the data etc. of exchcange core net and base station from home.
Fig. 1 is 3G household base station network Organization Chart, as shown in Figure 1,3G base station from home (HNB) is connected to home base-station gateway (HNB GW) by the Iuh interface of new definition, and home base-station gateway is provided to IuPS and the IuCs interface of core network packet-domain and circuit domain.Be essential deployment for home base-station gateway 3G network, be used for shielding the impact introduced to subscriber equipment (User Equipment, referred to as UE) and network side after base station from home.
Wherein, packet domain in Fig. 1 comprises: service universal grouping wireless serving GPRS support node (Service GPRS Support Node, referred to as SGSN) and gateway general packet wireless service support node (Gateway GPRS Support Node, referred to as GGSN).
For LTE network, home base-station gateway is optional deployment, and therefore LTE base station from home and core net are connected with two kinds of modes, and one is that base station from home is directly connected with core network element, specifically can see Fig. 2.Another kind is that base station from home is connected with core network element by gateway, specifically can see Fig. 3.For the scene introducing home base-station gateway shown in Fig. 3, home base-station gateway can not integrated user plane functions, directly sets up user face, thus can make the flattening of user face between base station from home and core network user veil close, data transmission delay reduces, specifically can see Fig. 4.
Wherein, Fig. 2,3, core network gateway in 4 is (also referred to as user plane gateway, i.e. system Long Term Evolution gateway (System Architecture Evolution Gateway, referred to as SAE-GW)) comprising: gateway (Serving Gateway, referred to as S-GW) and packet data network gateway (Packet Date Network Gateway, referred to as P-GW).
Closed user group (Closed Subscriber Group, referred to as CSG) is the concept proposed after introducing base station from home.Usually, the user of one family or an enterprises forms a closed user group, and this closed user group CSG ID identifies.For the base station from home of user's service in this closed user group has identical CSG ID.User, by contracting with operator, can be linked into the base station from home corresponding to multiple closed user group, such as, and the office space, family etc. of user.Therefore the concept allowing closed subscriber group list is introduced.Above-mentioned list is kept in the home subscriber data server of subscriber equipment (User Equipment, referred to as UE) and network side.Wherein, for LTE network, the home subscriber data server of network side is home subscriber server (Home Subscriber Server, referred to as HSS); For 3G network, the home subscriber data server of network side is attaching position register (Home Location Register, referred to as HLR).UE mainly utilizes above-mentioned list to carry out the selection of wireless area, base station from home can by the mode of broadcast by the CSG ID belonging to it and using forestland notice UE, after UE gets broadcast, if find that this base station is closed using forestland, and CSG ID is not in the permission closed subscriber group list self preserved, then UE thinks that this base station from home community is not suitable for access, and automatically select other to be applicable to the community of access, UE can be avoided in this way to carry out access attempts frequently, reduce the consumption of battery and interface-free resources.When UE carries out initialization access time, the permission closed subscriber group list that the home subscriber data server of network side can be contracted user is sent to the mobility management unit of core net, and the mobility management unit of core net can utilize above-mentioned list to carry out access control to UE.Wherein, for 3G network, mobility management unit is SGSN; For LTE network, mobility management unit is Mobility Management Entity (Mobility Management Entity, referred to as MME).If UE is by undelegated closed mode base station from home access core net, then core net can refuse the access of such UE.Base station from home also can use as ordinary base station, and now the access module of base station from home is open (OPEN) pattern.Under this pattern, base station from home can be accessed by any UE, and from the UE that above-mentioned pattern accesses, mobility management unit does not need to do access control to the UE of access yet.Equally, base station from home can have mixed mode, adopts closed mode access, adopt open mode to a part of UE to a part of UE.
When UE is in idle condition, air interface Connection Release between UE and base station, if there is external data to need to send to UE by network, then MME/SGSN needs to notify this UE of base station calling in the current residing tracking area list (TA List) of UE, to notify that this UE sets up air interface and connects; When there is home base-station gateway, MME/SGSN needs to notify home base-station gateway, by home base-station gateway informing base station paging UE.According to the different network architectures, when MME and base station from home direct-connected time, MME knows the access module of base station from home; When MME/SGSN is connected with base station from home by home base-station gateway, MME/SGSN does not know the access module of this base station from home, only has home base-station gateway to know the access module of this base station from home.
