Abstract
The embodiment of the invention relates to a method, device and system for selecting a public land mobile network. The method comprises the steps that eNodeB acquires PLMN information of a CSFB; the eNodeB determines a target cell switched by a packet switching domain according to the PLMN information of the CSFB. The PLMN information of the CSFB is acquired through the eNodeB, the eNodeB can determine the target cell switched by the packet switching domain according to the acquired PLMN information of the CSFB, therefore, the target cell is switched to a PLMN where an MSC/VLR attached to by UE in an EPS network is located, the situation that the eNodeB cannot sense the PLMN where the MSC/VLR attached to by the UE in the EPS network in the CSFNB process is located, different PLMNs are selected, and the additional processing delay of the CSFB process is caused is avoided, and the success rate of services is improved.
Description
Technical field
The present embodiments relate to mobile communication technology field, more particularly to a kind of public land mobile net（Public
Land Mobile Network, abbreviation PLMN）System of selection, apparatus and system.
Background technology
Evolved universal GSM land radio access web（Evolved Universal Mobile
Telecommunication System Territorial Radio Access Network, abbreviation E-UTRAN）And evolution
Packet-based core networks（Evolved Packet Core Network, abbreviation EPC）Constitute evolved packet system（Evolved
Packet System, abbreviation EPS）.And due to before operator intention many business all operate in the circuit of 2G/3G（Circuit
Switching, abbreviation CS）In domain, in order to reuse existing CS domains business in EPS networks, therefore propose by EPS networks
CS domain core nets are connected to, so that user equipment（User Equipment, abbreviation UE）Can initiate and receive in EPS networks
CS business, and 2G/3G networks completion CS business is returned to by E-UTRAN, its network architecture and processing method are properly termed as " circuit
Domain dropping "（CS Fallback, abbreviation CSFB）.
In above-mentioned CSFB flows are performed, UE performs joint attachment/joint tracing section updating flow from EPS in E-UTRAN
Network registry is to CS domain core nets equipment mobile switching centre/visitor location register（Mobile Switching
Center/Visitor Location Register, abbreviation MSC/VLR）On.In above process, mobility management entity
（Mobility Management Entity, abbreviation MME）It is responsible for the suitable MSC/VLR of selection, now according to the business of operator
Industry is set, and MME may select one from the EPS networks that UE adheres to there are different public land mobile nets to identify（PLMN ID）
MSC/VLR so that the UE perform CSFB processes fall back to 2G/3G networks when, access MSC/VLR where PLMN, complete
Follow-up CS domains business.
A kind of method that execution CSFB processes fall back to 2G/3G is evolved base station（Evolved NodeB, referred to as
eNodeB）Perform packet-switched domain switching（PS Handover, abbreviation PS HO）Flow, is that UE selects suitable target 2G/3G
Cell, completes CSFB treatment, and wherein cell is by cell ID（Cell ID）To be marked, and this is included in cell ID
PLMN ID are contained in PLMN information belonging to cell, i.e. Cell ID.But eNodeB cannot be perceived in joint attachment/joint
PLMN ID in tracing section updating flow where the selected MSC/VLR of MME, now, the selected Target cell institutes of eNodeB
The PLMN ID of category may be different from the PLMN ID where the MSC/VLR of above-mentioned MME selections so that eNodeB may be should
The switching target 2G/3G cells of UE selections belong to other PLMN, so due to changing after UE is stationed target 2G/3G cells
PLMN is become, the cell is serviced by other MSC/VLR, so as to cause the UE required execution position areas before CS business is carried out
Update（Location Area Update, abbreviation LAU）Flow is registered to this new MSC/VLR, for the feelings be called/exhaled eventually
The MSC/VLR of condition, this new MSC/VLR and UE registrations before also needs to execution roaming and retries（Roaming Retry）Flow
To complete called flow, above-mentioned extra location area updating and roaming retry the processing delay that flow increased CSFB flows, drop
Low service success rate and Consumer's Experience.
The content of the invention
The embodiment of the present invention provides a kind of public land mobile net（Public Land Mobile Network, referred to as
PLMN）System of selection, apparatus and system, UE is in EPS networks in being used to avoid eNodeB due to that cannot perceive CSFB flows
PLMN where the MSC/VLR of attachment and select the extra process time delay of CSFB flows caused by different PLMN, improve business
Success rate.
A kind of system of selection of public land mobile net is the embodiment of the invention provides, including：
ENodeB knows the PLMN information of CSFB；
The eNodeB determines the Target cell of packet-switched domain switching according to the PLMN information of the CSFB.
The embodiment of the present invention additionally provides a kind of evolved base station, including：
Know module, the PLMN information for knowing CSFB；
Determining module, for the PLMN information according to the CSFB, determines the Target cell of packet-switched domain switching.
The embodiment of the present invention additionally provides a kind of mobile management network element, including provides module, for being provided to eNodeB
The PLMN information of CSFB, the Target cell of packet-switched domain switching is determined for the eNodeB.
The embodiment of the present invention includes there is provided a kind of selection system of public land mobile net again：
