Abstract
The invention provides a method for changing core network nodes for mobile relay users. The method includes: an MRN (mobile relay node) detects change in current location and transmits change information to a current MME (mobility management entity) of UE (user equipment); the MME of the UE needing to be changed is determined according to the location information received by the current MME and other preset information of the UE, and change to the MME of the UE is triggered; a new MME group is selected for the UE through the MRN or the current MME, a new MME is selected from the new MME group on the basis of load balance; the new MME acquires UE context from the current MME, and UE P-GW (packet data network gateway) and UE S-GW (serving gateway) are determined for the UE. Core network nodes can be changed for the UE under the MRN by the method while a base station is unchanged by the UE, and transmission source load of UE data is effectively decreased.
Description
Technical field
The present invention relates to the technology in the mobile-relay system, particularly change the method for mobile relay user kernel net node.
Background technology
When the user took high ferro, LTE UE was by the MRN access LTE network of high ferro deploy and via the access of the UE P-GW in LTE network external network.Fig. 1 has provided a kind of network architecture from backhaul, to support UE access external network under the MRN.Wherein, MRN accesses MRN backhaul network (MME/S-GW/P-GW that comprises DeNB and service MRN) by DeNB, and is connected to the MME/S-GW that serves UE under the MRN by the MRN backhaul network, and UE is again by UE P-GW access external network.Two bold curves among the figure represent respectively S1-C between MRN and the UE MME and the S1-U between MRN and the UE S-GW.
Fig. 2 is the schematic diagram that the RN S-GW/RN MME of service MRN in the MRN running changes.As shown in Figure 2, MRN accepts the service of E-UTRAN node (DeNB) and core net (CN) node (comprising RN MME, RN S-GW and RN P-GW) in the MRN backhaul network.MRN can change the DeNB (MRN occurs to switch between DeNB) of access in moving process; When moving to another geographic area, MRN can change MME and the S-GW of service MRN in the process that changes the DeNB that accesses.RN P-GW in the MRN backhaul network links to each other with the UE core net, the routing node of communicating by letter with MRN as the UE core net.For UE under the MRN, UE one directly into the MRN residential quarter, can not change the base station, thereby the CN node of service UE (UE MME/UE S-GW/UE P-GW) just can't change also under the MRN in running.So the core network data of registered UE (chain of command and user's face) all can transmit via the S5/S8 interface between former RN P-GW and the new RN S-GW.
MRN serve its RN S-GW in continuous change, and the distance between the former RN P-GW increases constantly in moving process.Consider that mobile data services have occupied very large share and the positive rapid growth of user data demand in mobile service; the mutual mass data of frequent meeting during UE access Internet; then these data all need the transmission through S5/S8 interface between former RN P-GW and the new RN S-GW; this has just increased the demand to S5/S8 interface transfer resource, thereby increases the lower deployment cost of S5/S8 interface transfer resource.For burden, the saving lower deployment cost that has alleviated above-mentioned S5/S8 interface transfer resource, a part of UE data distribution need to be gone out--specifically can be that core net node with registered UE changes to the new nearer core net node of RN S-GW of distance, and make new UE core net node by the nearer RN P-GW of distance R N S-GW and new RN S-GW and with the UE interaction data, namely shunt the UE data that former RN P-GW and the S5/S8 interface of newly growing between the RNS-GW transmit by S5/S8 interface short between new RN P-GW and the new RN S-GW.
The base station of considering registered UE is constant (being MRN) all the time always, and the prior art of core net node that then changes UE is as follows: the constant base station of registered UE and change core net node; MME bears load-carrying balance.
For the consideration of network O﹠M, as MME because maintenance former thereby need to from MME Pool, be removed the time, perhaps when will increase new MME among the MME Pool, all or part of UE that OAM can indicate MME to unload it to serve.MME unloads UE, particularly:
For UE under the ECM-IDLE state of initiatively initiating TAU (upgrading timer such as periodicity TA stops) or ATTACH, MME finishes respective process and the indication base station discharges corresponding S1 connection;
For UE under the sluggish ECM-CONNECTED state (receiving the sluggish S1 Connection Release of the indication UE request of sending the base station such as MME), MME indication base station discharges corresponding S1 and connects;
MME should preferentially unload above-mentioned UE, if need to unload whole UE, then for residue UE, if both initiatively do not initiated TAU or ATTACH, not because the inactive S1 that is released connects, then MME can indicate the base station to discharge corresponding S1 connection again.
" MME indication base station discharges corresponding S1 and connects " particularly, refers to that MME comprises " load balancing TAU required " cause in the UE CONTEXT RELEASE COMMAND message that sends to the base station.The base station receives that the backward UE of UE CONTEXT RELEASE COMMAND message sends RRC connection release message (comprising " load balancing TAU required " cause in the message).UE carries out cell reselection after receiving the RRC connection release message, accesses selected residential quarter and initiates the TAU process.Wherein, UE does not comprise S-TMSI in the RRC connection request message that sends to the base station, also do not comprise GUMMEI in the RRC connection setup complete message that sends to the base station, then the base station just can judge that accordingly UE initiates the reason of TAU process, is that UE selects new MME based on load balance then.
In the above-mentioned processing, the trigger condition of MME unloading UE reckons without the burden that alleviates the UE data transmission resources, can't unload targetedly UE according to the situation of UE, thereby also just can't effectively alleviate the transmission pressure of S5/S8 interface transfer resource.
In addition, UE is different with MMEPool under the former MME with base station mobile stylish MME in a big way, does not also have consideration how to determine new MME Pool for UE at present.

Embodiment
For making purpose of the present invention, technological means and advantage clearer, below in conjunction with accompanying drawing the present invention is described in further details.
Basic thought of the present invention is: UE MME is according to the change of UE situation triggering UE MME, and MRN is that UE selects new UE MME.
The present invention provides two kinds of methods that change mobile relay user kernel net node, below by the specific implementation of two kinds of methods of specific embodiment explanation.
Embodiment one:
In the present embodiment, when carrying out the core net node variation, by the new UE MME of MRN selection of UE access.
Fig. 3 is the particular flow sheet that changes mobile relay user kernel net nodal method in the present embodiment.As shown in Figure 3, the method comprises:
Step 301 when the position that MRN detects self or accesses the UE of self changes, reports to self or the current location information that accesses the UE of self the current MME of the UE of access self.
Here, the MRN of UE and its access is on same position usually, and therefore, UE is identical with the positional information of the MRN of its access.Particularly, this positional information can be: the eNB ID/DeNB Global eNB ID of the DeNB of MRN access; The TAI/ECGI/CSG ID of the residential quarter of MRN access; The MME Group ID (MRN can from NAS GUMMEI obtain this information) of the MME of service MRN; Geographical area code (can be divided by operator, also can use administrative division), when positional information was administrative division, MRN can obtain this information by certain particular device (such as gps receiver).
, can use eNB Configuration Update message (MRN-＞UE MME), and in this message, increase the new IE of an expression positional information during to current MME (hereinafter referred to as the MME A) reporting position information of UE at MRN; Perhaps, also can use Location Report message (MRN-＞UE MME), because existing Location Report message can be carried ECGI or TAI, therefore, if positional information is ECGI or TAI, then can directly in this Location Report message, carry ECGI or TAI, if positional information is other positional information beyond ECGI and the TAI, then need in Location Report message, increase the new IE of an expression positional information.
Step 302, after MME A received described current location information, judging whether needed to change the UE core net node, if then execution in step 303, otherwise process ends.
Receive the positional information of MRN transmission at MME A after, determine that positional information changes, at this moment, need further to judge whether other presupposed informations of corresponding UE change, if also change, then judging needs to change the UE core net node, otherwise judging does not need to change the UE core net node.
Particularly, other presupposed informations of corresponding UE can be: UE type (for example, whether support many PDN connection, whether support SIPTO, if support SIPTO, whether the APN that then accesses allows to change P-GW); UE P-GW (for example reports the interior traffic conditions of UE Preset Time to UE MME (perhaps passing through OAM each other), be divided into high, medium and low Three Estate, the flow grade of UE P-GW statistics UE also reports to UE MME) or the traffic conditions in the right and wrong GBR carrying only; The ECM state (ECM-IDLE, ECM-CONNECTED) of UE; The situation of enlivening of UE business (for UE under the ECM-CONNECTED state) is such as the frequent degree of the foundation of the EPS of UE chain of command carrying, modification, release; The external network APN type of UE access (Internet as whether).A kind of or the combination in any of concrete presupposed information in can above-mentioned information.
Step 303, MME A triggers the MME that MRN changes UE.
The method that MME A triggers the change of UE core net node is specifically as follows: MME A sends UE CONTEXT RELEASE COMMAND message to MRN, carries cause " load balancing TAU required " in this message; Correspondingly, after MRN receives this message, send RRCCONNECTION RELEASE message to UE, and carry cause " load balancing TAU required " in this message.Just can use current mechanism to enter the RRC idle condition after UE receives, gravity treatment is to the MRN residential quarter, again by the MRN re-accessing network.So just need not change the operating mechanism of UE.Certainly, also can redefine as required the change that a reason triggers MME, still, need to make amendment to existing protocol.
Step 304, MRN is that UE determines the MME group, and selects new UE MME based on load balance for this UE in determined MME group.
In this step, MRN be UE determine new MME group concrete mode can for:
In MRN, dispose in advance self or access the UE current location information of self and the corresponding relation of MME group, perhaps self or the positional information that accesses the UE of self change the corresponding relation with the MME group, MRN is according to the corresponding relation of configuration, and the selection MME corresponding with the variation of current location information or positional information organizes; Wherein, corresponding relation can be configured by MRN OAM;
Perhaps, MRN reports to MRN OAM with current location information, is that MRN specifies the MME group by MRN OAM; When specifically carrying out the MME group selection, also can be in MRN OAM, to preserve in advance the UE current location information of MRN or access MRN and the corresponding relation of MME group, the positional information of perhaps preserving in advance the UE of MRN or access MRN in MRN OAM changes the corresponding relation of organizing with MME, MRN OAM is according to the corresponding relation of configuration, the MME group that selection is corresponding with the variation of current location information or positional information notifies the MME group of selecting to MRN.
After selecting the MME group, in this MME group, select new UE MME based on load balance for this UE.Concrete selection those skilled in the art all can realize, just repeat no more here.
Step 305, new UE MME obtains the context of this UE from MME A, and determines suitable UE P-GW and UE S-GW for this UE.
In this step, new UE MME from MME A obtain UE contextual method can for:
The context that new UE MME asks this UE by the path (being the realizing route among Fig. 2) of new RN P-GW, new RN S-GW, former RN P-GW to former UE MME, former UE MME returns the context of this UE by reverse path to new UE MME again, i.e. the routing forwarding node that transmits as S 10 interface IP bag between new UE MME and the former UE MME of new RN P-GW, new RN S-GW and former RN P-GW; Physical pathway between above-mentioned new RN P-GW, new RN S-GW and the former RN P-GW exists, and utilizes this physical pathway can realize the contextual transmission of UE.
Perhaps also can for:
New UE MME is obtained the context of this UE by former UE MME by the transfer resource between the UE core net (such as the forwarding through the operator backbone node).
The method of determining UE P-GW and UE S-GW can adopt existing mode, particularly:
New UE MME can be that UE selects nearer S-GW based on the UE current location information.Particularly, new UE MME can to self OAM report UE current location information, return the S-GW sign by MME OAM to MME;
New UE MME still keeps the original P-GW of UE constant, and will set up GTP tunnel for UE between new UE S-GW and the former UEP-GW;
For SIPTO UE, for being the corresponding APN of PDN connection that UE sets up at former UE P-GW, new UE MME determines whether to provide SIPTO function about this APN for UE, if, then a) new UE MME separates and activates the described PDN connection that has set up (indication " reactivation requested "), UE is during according to the indication request PDN connectivity procedure of former UE P-GW, and new UE MME will be the nearer new UEP-GW of the new UE S-GW of UE chosen distance; B) if UE needs reorientation GW at all PDN connection that former UE P-GW has set up, then UE MME can initialization " explicit detach with reattach required " procedure;
When supporting the UE request PDN connectivity procedure of many PDN connection, if corresponding the APN that does not set up relevant PDN connection, then new UE MME is the nearer new UE P-GW of the new UE S-GW of UE chosen distance, and sets up GTP tunnel for UE between new UE S-GW and the new UE P-GW.
So far, redefine MME, P-GW and the S-GW of UE, namely finished the change flow process of UE core net node.
Embodiment two:
In the present embodiment, when carrying out the core net node variation, by the new UE MME of current MME selection of UE.
Fig. 4 is the particular flow sheet that changes mobile relay user kernel net nodal method in the present embodiment.As shown in Figure 4, the method comprises:
Step 401 when the position that MRN detects self or accesses the UE of self changes, reports to self or the current location information that accesses the UE of self the current MME of the UE of access self.
The processing of step 401～402 is identical with the processing of step 301～302 among the embodiment one, just repeats no more here.
In this step, current MME be UE determine new MME group concrete mode can for:
Current MME determines new MME group based on the UE current location information of MRN or access MRN.
Current MME be UE determine new MME group concrete mode can for:
In current MME, dispose in advance the UE current location information of MRN or access MRN and the corresponding relation of MME group, perhaps the positional information of the UE of MRN or access MRN changes the corresponding relation of organizing with MME, MME is according to the corresponding relation of configuration, and the selection MME corresponding with the variation of current location information or positional information organizes; Wherein, corresponding relation can be configured by MME OAM;
Perhaps, current MME reports to MMEOAM with the UE current location information of MRN or access MRN, is that MME specifies the MME group by MME OAM; When specifically carrying out the MME group selection, also can be in MME OAM, to preserve in advance the UE current location information of MRN or access MRN and the corresponding relation of MME group, the positional information of perhaps preserving in advance the UE of MRN or access MRN in MME OAM changes the corresponding relation of organizing with MME, MME OAM is according to the corresponding relation of configuration, the MME group that selection is corresponding with the variation of current location information or positional information notifies the MME group of selecting to MME.
After selecting the MME group, in this MME group, select new UE MME based on load balance for this UE.Concrete selection those skilled in the art all can realize, just repeat no more here.
New UE MME from MME A obtain this UE contextual concrete mode can for: MMEA sends to this new MME with the context of this UE.Wherein, MME A can send by the path of former RNP-GW, new RN S-GW, new RN P-GW, also can send by the transfer resource between the UE core net (such as the forwarding through the operator backbone node).
Wherein, identical with existing processing mode for the processing of the new GUTI (for example, by GUTI REALLOCATION COMMAND message) of UE configuration, just repeat no more here.
The processing of this step is identical with the processing of step 305, just repeats no more here.
So far, the core net node in the present embodiment changes the method flow end.
Specific implementation by the invention described above as seen, two kinds of methods that embodiment one and embodiment two provide all can not change in the situation of base station at UE, for UE under the MRN changes core net node, effectively to alleviate UE data transfer resource burden.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
