Description
Technical field
The present invention relates to the network communications technology, refer to realize under a kind of connection mode the method that network is shared especially.
Background technology
The R6 version of WCDMA standard has numerous characteristics, and it is one of them key property that network is shared.Described network is shared and is meant a plurality of operators under the situation that guarantees proper communication, part or all of shared whole network.The implementation that network is shared has multiple, from saving the angle of investment, mainly be to wireless access network (RAN, Radio Access Network) equipment shares, this shared advantage shows the following aspects: one, networking initial stage can be saved the networking investment of operator when being main purpose with the network coverage; Two, make operator can build the wider network in overlay area apace.
For the user, there are shared region and non-shared region in the network, so need the contracted user who belong to different operators be controlled respectively, make it only can insert self signatory network area, thereby make network realize normal sharing functionality.
When user terminal (UE) under the idle pulley during to network initiated service request message or location update message, core net (CN) can be judged at present position-region (LA according to the user signing contract information of configuration in the attaching position register (HLR), Location Area) be to accept or refuse to provide service to UE, promptly this user's who disposes among the HLR CAMEL-Subscription-Information can prevent that the user from illegally inserting the not signing-contract field of self.Described lane place includes one or more sub-districts.
But, if UE has been in connection mode, so UE between different districts to move for CN be sightless.Simultaneously, the RNC in the UMTS Terrestrial radio access network (UTRAN) also lacks the access that necessary information is controlled UE.Like this, the UE that is in connection mode may be linked into not signatory sub-district in moving process, and this situation is unallowed in network service.
In order to overcome the problems referred to above, introduce the notion of shared network region (SNA, Shared NetworkArea) among the 3GPP R5, share (Shared Network Supportin Connected Mode) function to support the network under the connection mode better.Described SNA includes one or more LA, and CN allows to insert the SNA tabulation by the corresponding relation of configuration SNA and UE for each UE generates, and controls the access situation of UE in each sub-district, makes UE can only obtain the network service in allowing the SNA that inserts.
Stipulate in the agreement, be in UE under the connection mode and the sub-district take place when moving, realize that by access control the process that network shares is as follows:
The corresponding relation of step 101, the pre-configured LA of CN and SNA, instantiation is seen Fig. 2.The data that dispose on the CN node comprise: self administer the LA in the service area, the LA around this service area, and the SNA of above-mentioned LA correspondence.
Step 102, because CN supports " the connection mode lower network is shared " function, so the Information Transfer process of CN node by the Iu interface sends to the RNC preservation with the LA that self is provided with and the corresponding relation of SNA.
The sub-district takes place when moving in step 103, the UE that is in connection mode, and this UE makes a call to CN and sets up or carry out Relocation.CN is by public identifier (Common ID) or migration request signaling messages such as (Relocation Request), and the permission access SNA tabulation that UE is identified (IMSI) and this UE sends to RNC.
Step 104, RNC are according to the corresponding relation of LA and SNA, and the permission of this UE access SNA tabulation is judged, if the permission of UE inserts the SNA of SNA and the affiliated LA correspondence of current area coincidence is arranged, show to allow UE to insert current area, otherwise RNC will refuse the access request of UE.
In this step, if UE uses dedicated channel to carry out transfer of data, have only in the system RNC can for this UE directly provide with CN between be connected, this RNC is called the Serving RNC (SRNC) of UE, other RNC in the system is called the Drift Radio Network Controller (DRNC) of this UE.In order to control the activity of UE better, when SRNC sets up or increase the Radio Link (Radio Link) of DRNC, DRNC should will successfully set up that the SNA tabulation of LA correspondence sends to SRNC under all neighbor cells of sub-district of Radio Link by response message, use during in order to follow-up switchings.
When UE is positioned at common signal channel, after the Target RNC of this UE (Target RNC) receives that sub-district/URA of UE upgrades (Cell/URA Update) message, transmit this message to SRNC, and the SNA tabulation of LA correspondence under the current area of self preserving is sent to SRNC by uplink signal transmissions indication (UplinkSignalling Transfer Indication) message.SRNC compares the SNA tabulation of LA correspondence under the current area and the permission access SNA tabulation of UE, allows UE to insert if both have coincidence, otherwise refuses the access request of this UE.
After UE was linked into current area and is in the DCH state, in order to switch between soft handover, direct-cut operation or system follow-up carrying out, RNC need indicate UE to measuring with the adjacent cells of frequency, alien frequencies or different system.At this moment, RNC will be according to the corresponding relation of LA and SNA, and the permission of this UE inserts the SNA tabulation, the adjacent cells of self is screened, and the cell ID that will allow UE to insert is controlled (Measurement Control) message by measurement and informed described UE.
Find out that from above process existing method need all under the situation of network enabled sharing functionality, could guarantee that correct execution is to access control and the associative operation of UE under the connection mode at RNC and CN.For a complete 3G commercial system, each network element that adopts in the system such as NodeB, RNC and CN etc., may be to be provided by different equipment suppliers.Even same equipment supplier, dissimilar network elements also may have different characteristics.If CN is " the connection mode lower network is shared " function of supported protocol regulation not, promptly CN can't be provided with and send SNA and tabulates to RNC, and so existing method just can't be carried out correct access control to UE, can't realize that promptly the network under the connection mode is shared.
Summary of the invention
In view of this, main purpose of the present invention is to provide and realizes the method that network is shared under a kind of connection mode, does not support at CN to guarantee that network carries out correct access control to UE under the situation of " the connection mode lower network is shared ".

Described SNA data comprise the corresponding relation of LA and SNA, and the permission of UE inserts the SNA tabulation.Wherein, the corresponding relation of LA and SNA can be used LA-SNA mapping table record, and a LA can belong to a plurality of SNA, and a SNA can comprise a plurality of LA.
The permission that each UE is provided with self inserts the SNA tabulation, and which SNA that is used to indicate which PLMN is that the permission of described UE inserts the zone, and wherein each UE adopts and self identifies for IMSI number, allows to insert instantiation such as Fig. 4 of SNA tabulation.
Because IMSI number have 15, and distribute to a UE for each IMSI number and use, if allow to insert the SNA tabulation for being provided with one each IMSI number, need configuration and the data volume safeguarded very huge.Therefore, in actual applications, be divided into the IMSI section according to certain rule with all IMSI number, and insert the SNA tabulation for each IMSI section is provided with corresponding permission.
In addition, the configuration management interface that provides at the RNC place can be patterned man-machine interface, also can be simple order line input window.
Step 302, according to the request of UE, CN issues Common ID or Relocation Request message is given RNC, carries described UE sign.Because CN does not support " the connection mode lower network is shared " function,, described Common ID or Relocation Request message do not insert the SNA tabulation so not carrying the permission of this UE.
After step 303, RNC received above-mentioned message, the permission that finds this UE according to the UE sign inserted the SNA tabulation.
In this step, be provided with according to the IMSI section if allow to insert the SNA tabulation, then find the IMSI section of this user terminal earlier according to the UE sign, the permission of the described IMSI section of reentrying inserts the SNA tabulation.
Step 304, RNC insert the SNA tabulation with the permission of UE, compare with the LA-SNA mapping table of self preserving.If the permission of UE inserts the SNA of SNA and the affiliated LA correspondence of current area coincidence is arranged, show to allow UE to insert current area, otherwise RNC will refuse the access request of UE.
Herein, because RNC supports " the connection mode lower network is shared " function,, do not give unnecessary details so the processing of this step is identical with step 104 among Fig. 1 herein.
By the above embodiments as seen, this connection mode of the present invention is realized the method that network is shared down, directly carries out the SNA data configuration at the RNC place, thereby under the CN situation that network enabled is not shared, by RNC UE is carried out correct access control, improved the service competition power of operator.
