Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
What deserves to be explained is that the technical scheme that the embodiment of the invention provides is mainly with long evolving system (Long Term Evolution, abbreviation LTE) describes for example, but being not limited thereto, can also be other communication systems, such as WCDMA or gsm system etc. or mixed networking system.
LTE MOCN scheme based on standard agreement, base station eNB is broadcasted multi-operator PLMN-ID tabulation in system message, during the UE access network, select the PLMN network identity of service, and the result that will select indicates to eNB, eNB will respect the selection result of UE, and this UE is routed to independently core net of respective operator.The problem that operator faces is: in MOCN shared network operation, and for the roamer, when the UE automatic mode is selected service network PLMN at random, the network selection of the uncontrollable UE of operator, thus can't realize distribution of interests between the operator.
At this technical problem, the embodiment of the invention provides various embodiments, below will be described respectively.Being understandable that the numbering of embodiment is just used for convenience, is not in order to compare between each embodiment.
Embodiment one:
This embodiment comprises the steps: that in MOCN MOCN sub-district broadcasting comprises the pairing a plurality of PLMN of a plurality of operators and reflects the system message of priority relationship between a plurality of PLMN; Receive the PLMN that user terminal UE sends according to the system message selection; According to the PLMN that UE selects, UE is routed to the core net of the PLMN correspondence of selection.
Wherein, can embody priority relationship between a plurality of PLMN in several ways.Mode one: in the system message, a plurality of PLMN have predefined putting in order, such as, can as required certain or certain PLMN be come the foremost, represent that the priority of this PLMN is higher than other PLMN.Mode two: in system message, each PLMN of a plurality of PLMN has priority level.
Further, if comprise the public PLMN that a multi-operator is shared among a plurality of PLMN, then, different processing modes can be arranged according to the difference that embodies the mode of priority relationship between a plurality of PLMN.Such as, when employing mode one embodied priority relationship, public PLMN can be arranged in before other PLMN in system message; When employing mode two embodies priority relationship, public PLMN in system message, can have the priority level higher than other PLMN (such as, the priority of public PLMN for priority high, other PLMN be in or low).
Accordingly,, then can UE be carried out route assignment between the pairing different operators of public PLMN, to realize between the shared network operator distribution of interests to the roamer according to predefined allocation proportion if UE selects is public PLMN.
Embodiment two:
Below in conjunction with application scenarios schematic diagram Fig. 1 and method flow schematic diagram Fig. 2, the embodiment of the invention is described.As shown in Figure 1, PLMN A represents the network of the A of operator, and PLMN B represents the network of the B of operator, and PLMN C represents the RAN shared network of A of operator and the joint construction of the B of operator, and PLMN C is the public PLMN that multi-operator is shared.
This method comprises the steps:
Step 201: in the MOCN sub-district, base station eNB is broadcasted the pairing PLMN list information of a plurality of operators of MOCN in system broadcast message, wherein, comprises the public PLMN that multi-operator is shared in the described PLMN tabulation;
The sub-district of inserting the shared core net of LTE with UE is an example, eNB broadcasts three PLMN information simultaneously, the arrangement of the PLMN information in this broadcast message can have default priority from high to low, and this default priority mainly acts on UE, is used to guide the PLMN of roamer UE to select.
This system message can reflect priority relationship between described a plurality of PLMN.
Concrete, can embody priority by the order of broadcasting PLMN tabulation, such as, adopt following putting in order: PLMN C-PLMN A-PLMN B, or, PLMN C-PLMN B-PLMNA.And in LTE MOCN shared network, a plurality of PLMN of system broadcasts can have substantially identical radio signal quality, its objective is that wishing that UE puts in order according to PLMN in the system broadcast message selects PLMN.
In addition, the priority of PLMN information can also realize by carrying priority tag.Such as, every kind of corresponding a kind of priority of PLMN, UE carries out the selection of PLMN according to the priority of the PLMN that receives.Same, this priority can be used for guiding the PLMN of roamer UE to select, such as, can be decided to be the priority of PLMN C the highest.
Further, because not all operation commercial city wishes that PLMN-id list carries priority, so, can be when the PLMN-id list of broadcasting, whether increase sign with priority.If whether this carries the true or existence of being designated of priority, show that then the PLMN among the PLMN-id list has corresponding priorities, in this case, UE can go earlier to check whether HPLMN is arranged among the PLMN-id list, if no, so just select according to the priority of the PLMN that receives.Certainly, if whether this carries false or the non-existent words of being designated of priority, UE just is considered as equal priority to all PLMN-id so, can select at random according to prior art.
What deserves to be explained is, in below describing, be example in the mode that embodies priority by broadcasting PLMN tab sequential mainly.
Step 202:UE carries out the PLMN selection according to the PLMN list information of eNB broadcasting;
Concrete: UE is initially starting shooting, is falling under the scenes such as net gravity treatment, network refusal, all will trigger PLMN and select or the gravity treatment flow process.UE generally will after the location registers success, finish to select or reuse adoption process according to the suitable service PLMN of certain selective sequential.With regard to the PLMN-idlist of Home PLMN and system broadcasts, ordinary priority is selected Home PLMN.
Concrete, for the contracted user of A of operator and the B of operator, will preferentially select the Home PLMN of oneself.Such as, for the contracted user 1 of the A of operator, PLMN A is Home PLMN (Home PLMN is called for short HPLMN) for this user, this contracted user 1 can select PLMN A; For the contracted user 2 of the B of operator, PLMN B is HPLMN for this user, and this contracted user 2 can select PLMN B.But for the roamer, because PLMN A or PLMN B are not its HPLMN, terminal UE will preferentially be selected the 1st PLMN, i.e. PLMN C broadcasting.
Be understandable that PLMN selects also to relate to RPLMN and selects processes such as (previous position is registered successful PLMN) or equivalent HPLMN selection in the prior art, owing to the technical scheme with the embodiment of the invention does not directly concern, is not described in detail.
The service PLMN that step 203:UE will select by signaling message sends to eNB;
During the terminal UE access network, carry the service PLMN of selection to eNB by signaling message.Concrete, UE selects according to the PLMN of back, carries out cell selecting, location registers and service request subsequently, and can take the PLMN that selects to base station eNB by " RRCConnectionSetupComplete " signaling message this moment.The format sample that is somebody's turn to do " RRCConnectionSetupComplete " signaling message is as follows, and wherein, selectedPLMN-Identity has represented the PLMN that selects.
Step 204:eNB is routed to this UE the core net of respective operator according to the PLMN information that UE reports;
Concrete, eNB is based on the PLMN information that UE reports, and can judge this UE is a roamer or a local user:
1) if UE selects is PLMN A, then eNB judges that this UE is the local user of the A of operator, then is routed to this UE the core net of the A of operator;
2) if UE selects is PLMN B, then eNB judges that this UE is the local user of the B of operator, is routed to this UE the core net of the B of operator;
3) be PLMN C if UE selects, then eNB judges that this UE is a roamer (because PLMN A or PLMN B are not its HPLMN), then, be routed to the core net of A of operator or the B of operator in proportion according to the distribution of interests ratio between A of operator and the B of operator.Concrete, can carry out this ratio of as offered by operator, such as 50%-50% or 30%-70% etc., the embodiment of the invention is not done qualification.
What deserves to be explained is:
If this UE be with a side wherein have roaming agreement the user (such as and the A of operator roaming agreement is arranged), according to above-mentioned 3) the core net selected of mode may not have roaming agreement (this UE being routed to the core net of the B of operator such as eNB) with this UE, then do not have the core net of roaming agreement to issue refuse information by NAS information with this UE, eNB transmits NAS information according to normal register flow path to UE.Afterwards, UE will not reattempt PLMN C, but remove to attempt PLMNA and PLMN B, and finally this UE only can be had the core net of roaming agreement to accept with it.
Certainly, if this UE is the user that roaming agreement is arranged with both sides, then such user just can realize inserting pari passu different shared operator core net according to the method described above.
Can learn that by above description the technical scheme by this embodiment provides can realize the control to the UE network selection, realize that the balance of interest for the roamer maximizes between shared network operator.
In addition, the embodiment of the invention provides the implementation of multiple embodiment PLMN priority, makes technical scheme more flexible, can satisfy the demand of different scenes and different operators.
