Abstract
This invention provides a realization method for selectivity migration in a share network used in migrating between the share network and the attribute network by user devices including: A, selecting local areas allowed to be migrated, B, testing said local areas, C, selecting areas that meet the conditions and migrating them.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method that subscriber equipment carries out selective migration of in shared network, controlling.
Background technology
It is that one or more operators provide funds to build the UMTS network jointly that network is shared, and perhaps rents the UMTS network of other operators.Shared network can only comprise UTRAN, also can comprise portion C N simultaneously, main application form has colocation site, Node B (base station) to share, RAN shares, CN shares etc., in the present invention, be that example is described with Partial CN Sharing Network (local core network is shared) scene.
Fig. 1 shows the typical networking diagram of Partial CN Sharing Network, the C of operator has built a complete set of UMTS network, and shared UTRAN network and portion C N network to A of operator and the B of operator, the C of operator has the CN network of oneself, also may not have the CN network of oneself.
Network sharing functionality under the connection mode is introduced in 3GPP Rel 5, it is a necessary condition of the complete realization of network sharing functionality, particular UE can only obtain service in the SNA that allows its access, utilize the SNA access control function, network can carry out access control to particular UE, a SNA comprises one or more LA, can be overlapping between the SNA.
When upgrading in the service request of initiating to network under the idle pulley or position, support the network of 3GPPRel 99 or Rel 4 technical specifications to accept according to user's CAMEL-Subscription-Information or refusal provides service in some lane place to this UE by CN for UE; If but UE is in connection mode, comprise under Cell-DCH, Cell-FACH, Cell-PCH, the URA-PCH, moving of UE is invisible to CN, UTRAN lacks necessary judgement information and stops UE to switch to without in the signatory lane place that allows, so network is inconsistent to UE in the mobile access restriction under the idle pulley and under the connection mode.
Specifically, the user A of the A of operator is except the shared network that the use C of operator provides, can also use the A of operator self networks A, in this case, require shared network can control user A, and can from shared network C is moved to the network B of the B of operator, not go only in the migration of carrying out between network A and the C under the connected state.
Fig. 2 shows the flow process that UE carries out network migration in the prior art under connected state:
Among the step S201, because factors such as covering, capacity or type of service trigger UE and initiate migration, UE need be moved to the home network A from shared network C, with the migration based on covering is example, in SharedRAN, user A has reached the thresholding of network settings because residing Serving cell signal quality is relatively poor, form by measurement report is notified to Shared RAN, initiates migration;
Among the step S202, UE carries out mass measurement to the adjacent area of current service cell, and to Shared RAN reporting measurement result;
Among the step S203, the Target cell that network selecting allows UE to switch issues the Target cell tabulation to UE;
Among the step S204, UE selects suitable Target cell, implements migration.
Is example with UMTS to the GSM migration, mainly controls the selective migration of UE by dual mode:
First kind of mode is after Shared CN receives migration request from Shared RAN, judges whether to allow switching target small area according to user's IMSI information, thereby finishes the control of selective migration.
The major defect of this mode is:
(1) in the CS territory, UE needs the quality of measurement target adjacent area in the cell measurement stage, the target adjacent area has comprised the related cell of fortune network A and network B, for user A, the sub-district of Measurement Network B is insignificant, has reduced the efficient of UE measurement adjacent area, influences handover success rate, Shared CN need judge whether to allow to switch according to IMSI information simultaneously, has increased the processing load of Shared CN.
(2) for the process of PS territory UMTS to the GSM/GPRS migration, Shared RAN generally can not initiate migration request to Shared CN, so Shared CN is with the migration of uncontrollable UE at PS territory connected state.
The second way is that Shared RAN judges whether to allow UE to switch to Target cell according to SNA access control information, thereby finish control to the UE migration, promptly each relevant LA of configuration (comprises the LA in this CN node coverage in the CN node, and " contiguous LA " around this CN node coverage) affiliated SNA information, the CN node sends to RNC by the Iu connection with these configuration informations; When call setup or SRNC migration, the CN node sends to RNC by the access restricted information that Iu connects this UE, in calling procedure, DRNC also can send to SRNC with the SNA configuration information of Target cell or its adjacent area by the Iur interface, so that SRNC limits the candidate target cells that this UE switches.
For the process of PS territory UMTS to the GSM/GPRS migration, different conditions according to UE, the process of migration is different, and when UE is under CELL_DCH or the CELL_FACH state, the migration of UE can be controlled the selection of migration Target cell by similar above-mentioned CS domain migration by Shared RAN; When UE is under CELL_FACH or CELL_PCH or the URA_PCH state, to finish of UE migration by the sub-district gravity treatment that UE initiates, promptly when UE carries out location registers or adheres to, Shared CN is at the user of heterogeneous networks, IMSI based on the user judges, in LAU or RAU or ATTACHACCEPT message, issue different EPLMN tabulations, make the user of heterogeneous networks different network selection abilities be arranged at Idle state.
Therefore, in this mode, for the UE that is in CS territory connected state or be in PS territory CELL_DCH or the CELL_FACH state under UE in the cell measurement stage, and be in UE under PS territory CELL_FACH or CELL_PCH or the URA_PCH state in order to finish the sub-district gravity treatment, the target adjacent area that need measure has comprised the related cell of A of operator and B, and for user A, the sub-district of measuring the B of operator is insignificant, reduce the efficient of UE measurement adjacent area, influenced migration success rate.

Fig. 3 shows UE migration flow process provided by the invention,
Among the step S301, initiate migration because factors such as covering, capacity or type of service trigger UE, UE need be moved to the home network A from shared network C.
Among the step S302, select to allow the Target cell of migration.
Among the step S303, UE carries out mass measurement to the sub-district that allows migration, and to Shared RAN reporting measurement result;
Among the step S304, UE selects to satisfy the Target cell of transition condition, implements migration.
As one embodiment of the present of invention, allow the Target cell of UE migration to control by Shared RAN, is example with CS territory UMTS to the GSM migration, after Shared RAN receives measurement report, according to the Neighboring Cell List of current service cell, comprise the related cell of A of operator and B and this user's SNA access control information usually simultaneously, Neighboring Cell List is filtered, as shown in Figure 4:
Among the step S401, Shared RAN obtains the Neighboring Cell List of backstage configuration according to current service cell or best cell;
Among the step S402, Shared RAN judges whether the sub-district in the Neighboring Cell List belongs to SNA, is execution in step S403 then, otherwise execution in step S404;
Among the step S403, keep this sub-district;
Among the step S404, abandon this sub-district;
Among the step S405, Shared RAN sets up new Neighboring Cell List, and issues to UE by measuring control information.
For the UE that is under PS territory CELL_DCH or the CELL_FACH state, the selection of Target cell is identical with CS territory connected state during migration; For the UE that is under PS territory CELL_FACH or CELL_PCH or the URA_PCH state, to finish of UE migration by the sub-district gravity treatment that UE initiates, promptly when UE carries out location registers or adheres to, Shared CN is at the user of heterogeneous networks, IMSI based on the user judges, in LAU or RAU or ATTACH ACCEPT message, tabulate the target cell information that makes the permission migration that UE obtains by issue EPLMN to UE.
As another execution mode of the present invention, allow the Target cell of UE migration to control by UE self.When connection was set up, Shared RAN sent to UE by connected state message with SNA information; When SNA access control information changed under the UE that is in connected state, Shared RAN sent to UE as measuring control messages with new SNA access control information by connected state message, and UE upgrades at any time the SNA access control information of self and preserves.When needs were measured the adjacent area, UE filtered measuring the adjacent area according to Shared RAN Neighboring Cell List that issues and the SNA information of self preserving, and the sub-district of selecting to allow to move is measured.
UE is when carrying out LAU or RAU flow process, network transmits SNA access control information by LAU or RAU Accept message to UE, when the two SNA information inconsistency, UE can adopt two territory SNA to get to occur simultaneously or safeguard SNA information in the mode that one of them territory is as the criterion.
When UE was in CS territory CELL_DCH state, when the migration in the same LA took place in Shared CN, the SNA information of UE need not to change; When striding the migration of LA in Shared CN, network transmits SNA access control information by measuring control information to UE.When UE was in PS territory CELL_DCH or CELL_FACH state, when the migration in the same RA took place in Shared CN, the SNA information of UE need not to change; When striding the migration of RA in Shared CN, network transmits SNA access control information by measuring control information or by the RAU flow process to UE.During for the migration of composite service in Shared CN, network transmits SNA information by measuring control or RAU flow process to UE; When the two was inconsistent, UE can adopt two territory SNA to get common factor or safeguard SNA information in the mode that one of them territory is as the criterion;
UE is in CELL_FACH or CELL_PCH or URA_PCH state, and when cell update or URA renewal took place, if LA or RA do not change, then the SNA access control information of UE can not change; If LA or RA change, then UE upgrades the SNA access control information of self by LAU or RAU.
