Description

A kind of addressing method and device for addressing of cell switching

Technical field

The present invention relates to communication technical field, more particularly to the addressing method and device for addressing that a kind of cell switches.

Background technology

In long-term evolution upgrading (Long Term Evolution-Advanced, LTE-A) system, covered to increase network Lid introduces via node (RN), and RN is wirelessly connected with donor base station (Donor evolved Node B, DeNB). At present, an importance of RN applications is applied in the high-speed mobile environments such as railway, by the middle part of high-speed mobile environment Administration RN, the signal quality in car body can be strengthened, it is also possible to reduced by group's switching user equipment (User Equipment, UE switching times), can also reduce UE carries out the number of times of location updating, typically claims the RN disposed in high-speed mobile environment It is mobile RN.

In order to preferably support the mobility of RN, a node for offer mobile anchor point function can be introduced, typically should Node is referred to as mobile anchor point (MobilityAnchor, MA), and Fig. 1 shows the network after deploying mobile RN and mobile anchor point Node relationships schematic diagram, wherein, the connecting interface of thick line mark represents the interface related to mobile RN, and the connection of fine rule mark connects Oral thermometer shows the interface related to UE.In Fig. 1, mobile RN is linked into core by the donor cell (donor cell) under DeNB Net, and core net does not have direct wireline interface, and each movement RN can control one or more cells.Under this framework, UE And the interface between mobile RN is referred to as Uu interfaces, the interface between mobile RN and DeNB is referred to as Un interfaces, DeNB and mobile anchor point Between interface be referred to as S1-C interfaces, mobility management entity (the Mobility Management of mobile anchor point and RN Entity, MME) between interface be referred to as S5 interfaces, the gateway (Serving Gateway, SGW) of mobile anchor point and UE it Between interface be referred to as S1-U interface, the interface between the MME of the SGW and UE of UE be S11 interfaces.In the network node shown in Fig. 1 In relation schematic diagram, mobile RN has the dual identity of UE and base station (eNB).When mobile RN is used as UE, mobile RN and network Between establish evolution grouping system (Evolved Packet System, EPS) carry, have oneself chain of command management section Point MME, and gateway node SGW and grouped data domain gateway (Packet Data Domain Gateway, PGW) node；When When mobile RN is as eNB, mobile RN provides wireless backhaul link for the UE for accessing, and manages Radio Resource.

After introducing mobile anchor point in a wireless communication system, following advantage can be brought：

On the one hand, mobile anchor point can provide SGW and PGW functions for mobile RN, and can be held for mobile RN sets up EPS Carry.It is independent equivalent to the SGW and PGW of mobile RN are placed on when mobile anchor point provides SGW and PGW functions for mobile RN In node (i.e. mobile anchor point), so as to avoid moving the processing procedure that RN changes SGW and PGW in moving process.Also, introduce After mobile anchor point, when mobile RN needs to be switched to another DeNB, mobile RN only changes serving BS (i.e. DeNB), the movement The MME and target DeNB of RN set up S1-C signaling connections, mobile anchor point will mobile RN the S1-U tunnels that carry of EPS from source DeNB It is transferred to target DeNB.

On the other hand, mobile anchor point can provide the agent functionality based on S1 interfaces or X2 interface.Based on this function, for For the UE accessed from mobile RN, in up direction, the related signalings of UE are dealt into mobile anchor point by mobile RN, will by mobile anchor point UE related signaling is sent to the MME of UE；In down direction, S1 signalings are first sent to mobile anchor point by the MME of UE, then by mobile anchor point It is sent to the serving BS (moving RN) of UE.Data for UE, in up direction, the SGW of UE are issued by mobile anchor point；Under The data of UE are issued mobile anchor point by line direction, the SGW of UE, and the serving BS for then issuing UE again by mobile anchor point (is moved RN).So the equipment of the core network (such as MME or SGW) relative to UE, the serving BS for being functionally similar to UE of mobile anchor point, In this case, after mobile RN is switched to different DeNB, the equipment of the core network of UE can not perceive the movement of UE, so as to subtract Influence of the whole handoff procedure to the core net node of UE is lacked.

Fig. 2 shows the network node relation schematic diagram after the mobile RN of another deployment and mobile anchor point, the Fig. 2 and figure 1 difference is：UE data directly issue the SGW of UE from DeNB, rather than the SGW for issuing UE again through mobile anchor point, so as to subtract Lack the path of data transfer, decrease the burden of the data processing of mobile anchor point.Based on this framework, when mobile RN is switched to After different DeNB, the core net of UE needs to know the movement of UE, so as to data forwarding paths are transferred into new DeNB. In framework shown in Fig. 2, DeNB can provide the agent functionality based on S1 or X2 interface for mobile RN, that is, move RN and DeNB builds Be based on the connection of S1 interfaces or X2 interface, and DeNB sets up the connection based on S1 interfaces or X2 interface with mobile anchor point.Except above-mentioned Difference is outer, and the situation of Fig. 2 is essentially identical with the situation of Fig. 1, specifically refers to the description for Fig. 1.

In a communications system, eNB general management multiple cells, eNB be before UE services it needs to be determined that its management it is every The cell ID of individual cell, that is, determine the cell ID that each cell is used in Uu interfaces.Specifically, cell ID mainly includes Tracking area identification (Tracking Area Identity, TAI) and the universal land radio access web (Evolved of evolution Universal Terrestrial Radio Access Network, EUTRAN) Cell Global Identifier (E-UTRAN Cell Global Identity, ECGI), wherein, TAI represents the position area belonging to the cell；ECGI is general by 28 bit data groups Into, ECGI preceding 20 bit be identified cell ownership base station global unique identification, remaining 8 bit is by being identified The base station distribution of cell ownership, when 8 bit data is distributed, it is necessary to ensure that the ECGI of each cell is unique.Needed when there is UE When being switched to another cell, the cell ID of Target cell can be carried and is sent in handover request by the source eNB of the UE The target eNB for determining.At present, cell ID configuration is mainly carried out by OAM, i.e., the TAI that will be distributed for eNB by OAM and ECGI is configured to eNB, wherein, OAM needs to ensure as the ECGI of each cell configuration is different.

DeNB can provide S1 interfaces or X2 interface agent functionality for the UE accessed from mobile RN, based on this function, when When DeNB access networks, the connection based on S1-C interfaces can be set up with MME, and be connected with mobile anchor point foundation, wherein, DeNB and mobile anchor point are set up and are connected with two ways, and one kind is that to regard mobile anchor point be MME to DeNB, in the case, DeNB and Mobile anchor point sets up the connection based on S1-C interfaces；Another kind is that to regard mobile anchor point be adjacent base station to DeNB, in the case, DeNB The connection based on X2 interface is set up with mobile anchor point.

In the communication system of mobile RN and mobile anchor point is introduced into, the important problem for facing is cut facing UE How cell addressing is carried out when changing, it is clearly inapplicable to continue to continue to use the method for cell addressing when UE in existing communication system switches , the Signalling exchange flow of cell addressing is made a concrete analysis of when switching below in conjunction with UE in existing communication system：

The schematic diagram of the Signalling exchange flow of cell addressing when Fig. 3 shows that UE switches in existing communication system, such as Fig. 3 institutes Show, the interaction mainly comprises the following steps：

Step 301, UE when needing to carry out S1 and switching, to its source base station (Source eNB) reporting measurement reports (Measurement Report)；

Measurement result in the measurement report that step 302, the source base station of UE are reported according to UE switches over judgement, determines It is adapted to the Target cell of switching, and handover request message (Handover Required) is sent to the source MME of UE, wherein, switching The TAI of the Target cell determined and global Base Station Identification (Global eNB ID) are carried in request message；

The TAI of the Target cell that step 303, source MME are carried according to handover request message finds target MME (Target MME forward re-positioning request (Forward Relocation Request), the request), and to the target MME for determining are sent The middle TAI for carrying Target cell and global Base Station Identification；Wherein, source MME can go domain name system according to the TAI of Target cell (Domain Name System, DNS) server lookup services the IP address letter of the MME of the TAI, the knot that dns server is returned Fruit is probably multiple MME, and source MME can therefrom select one as target MME；

Step 304, target MME determine unique target BS (Target eNB) according to target whole world Base Station Identification, and Handover request (Handover Request) is sent to the target BS, the TAI of Target cell and complete is carried in the handover request Ball Base Station Identification；

Step 305, target BS obtain the target cell information of source base station selection from handover request message, are that UE is reserved After resource, switching request acknowledgement message (Handover Request Acknowledge) is returned to target MME；

Step 306, target MME send forward relocation response (Forward Relocation to source MME Response)；

Step 307, source MME send the switching command (Handover Command) that target BS is generated to source base station；

Step 308, source base station send RRC link reconfiguration messages (RRC Connection to UE Reconfiguration)；

Step 309, UE and Target cell set up RRC connections, and returning to RRC connections to target BS reconfigures completion message (RRC Connection Reconfiguration Complete) is confirmed；

Step 310, target BS send handoff notification message (Handover Notify) to target MME；

Step 311, target MME update the positional information of UE, and change downlink data transmission path.Finally, target MME to Source MME sends forward and relocates completion notice (Forward Relocation Complete Notification)；

Step 312, source MME send UE resource release commands (UE Context Release Command) to source eNB, release Put the resource of UE.

So far, the flow of cell addressing terminates when UE switches in existing communication system.

After communication system introduces mobile anchor point, mobile anchor point can typically be deployed between DeNB and the MME of UE (such as Fig. 1 Or shown in Fig. 2), DeNB is no longer joined directly together with the MME of UE, namely mobile anchor point shields opening up between DeNB and the MME of UE Relation is flutterred, so as to when cell switching is carried out, target MME possibly cannot find suitable mobile anchor point, and mobile anchor point is likely to Cannot will switch related signaling exactly and be sent to correct mobile RN, so as to the accuracy for causing to be addressed in cell switch process It is low.

And in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined.

Embodiment one

The embodiment of the present invention one provides a kind of addressing method of cell switching, and the method is respectively for mobile anchor point to moving The process and target MME that dynamic RN is addressed give the process of implementing to the process that mobile anchor point is addressed, this two The cardinal principle that individual implementation process is based on is as follows：

First, the process that target MME is addressed to mobile anchor point

Target MME is addressed that i.e. target MME determines that target is moved after handover request message is received to mobile anchor point Dynamic anchor point.Wherein, the cell identity information of the UE Target cells to be switched to is carried in the handover request message, i.e. the target is small The TAI in area and global Base Station Identification.Wherein, the determination process of the target MME of UE switchings is existing procedure, no longer detailed herein Description.

Specifically, target MME determines the mobile anchor point for carrying out subsequent treatment to the handover request message, mainly passes through Two ways：

Determine the mode one of mobile anchor point

Target MME obtains the handover request message after handover request message is received from the handover request message for receiving The global Base Station Identification of the Target cell of carrying, and determine that mobile anchor point corresponding with the global Base Station Identification is that target is moved Anchor point.

It is the processing procedure in the mode one for realizing the determination mobile anchor point, it is corresponding complete that system can be pre-configured with mobile RN Ball Base Station Identification is identical with the global Base Station Identification of the mobile anchor point that movement RN belongs to.Specifically, the configuration process can be by Operation and maintenance system (Operation and Maintenance, OAM) system is configured.

Determine the mode two of mobile anchor point

Target MME obtains the handover request message after handover request message is received from the handover request message for receiving The TAI of the Target cell of carrying, from each mobile anchor point for corresponding to different TAI respectively, determines TAI pairs with the Target cell The mobile anchor point answered is target mobile anchor point.

It is the processing procedure in the mode two for realizing the determination mobile anchor point, system can in advance for different mobile anchor points is matched somebody with somebody Put different TAI, i.e. mobile anchor point different, then corresponding TAI is also different.Specifically, the configuration process can be entered by OAM systems Row configuration.

Mode one or mode two based on above-mentioned determination mobile anchor point, system can configure the mobile anchor point of mobile RN and ownership With identical whole world Base Station Identification, or, each mobile anchor point of system configuration corresponds to different TAI respectively, so that target MME energy The corresponding information that enough cell IDs carried based on the handover request message for receiving are included is determined to enter handover request message The mobile anchor point of row subsequent treatment, completes the address procedures to mobile anchor point.

2nd, the process that mobile anchor point is addressed to mobile RN

Mobile anchor point is addressed to mobile RN, i.e. mobile anchor point after handover request message is received, it is determined that for right The handover request message carries out the mobile RN of subsequent treatment.Wherein, the handover request message that mobile anchor point is received is UE switchings What target MME sent.

Specifically, mobile anchor point determines the mobile RN for carrying out subsequent treatment to the handover request message for receiving, mainly By two ways：

It is determined that the mode one of mobile RN

Mobile anchor point obtains the ECGI of the Target cell of handover request message carrying from the handover request message for receiving, And ECGI according to the Target cell and corresponding ECGI of predetermined each mobile RN, determine the ECGI with the Target cell Corresponding mobile RN is that target moves RN.

It is the processing procedure in the mode one for realizing determination movement RN, mobile anchor point needs to predefine each mobile RN pairs The ECGI for answering.Wherein, mobile anchor point determines that the mode of the corresponding ECGI of mobile RN will be described in detail in subsequent embodiment, herein Wouldn't describe.

It is determined that the mode two of mobile RN

Mobile anchor point obtains the global Base Station Identification of Target cell from the handover request message for receiving and obtains in advance The corresponding global Base Station Identifications of each mobile RN, determine mobile RN corresponding with the global Base Station Identification of the Target cell be mesh The mobile RN of mark.

It is the processing procedure in the mode two for realizing determination movement RN, mobile anchor point needs to obtain each mobile RN pairs in advance The global Base Station Identification answered.Wherein, mobile anchor point obtains the corresponding global Base Station Identifications of mobile RN, can be by mobile RN or movement The donor base station of RN is reported, i.e., mobile anchor point can receive the movement RN correspondences that the donor base station of mobile RN or movement RN is reported Global Base Station Identification.Also, according to embodiments of the present invention one preferred embodiment for providing, donor base station can detected After the mobile RN changes of management, update the information of the mobile RN preserved in mobile anchor point, i.e. mobile anchor point and receive applying for mobile RN After the corresponding global Base Station Identifications of mobile RN that master base station is reported, it is also possible to the donor base station can be received and detecting management Mobile RN changes after corresponding global Base Station Identifications of mobile RN after the change that reports, so as to improve the every of mobile anchor point preservation The accuracy of the global Base Station Identification of the mobile RN connected under individual donor base station.

The mode one or mode two of RN are moved based on above-mentioned determination, mobile anchor point can be according to the Target cell to be switched ECGI information or global Base Station Identification, determine that target moves RN, complete to move target the address procedures of RN.

In the mode one of above-mentioned determination movement RN, mobile anchor point needs to predefine the corresponding ECGI of each mobile RN, specifically Ground, determines that the mode of the corresponding ECGI of mobile RN is described in detail to mobile anchor point below.

The present embodiment one provides the preferred implementation that two kinds of mobile anchor points determine the corresponding ECGI of mobile RN, following pin Both preferred implementations are illustrated respectively：

Mobile anchor point determines the preferred implementation one of the corresponding ECGI of mobile RN

In the preferred implementation one, mobile anchor point determines that the corresponding ECGI of mobile RN, i.e. mobile anchor point receive mobile RN The composition information of the corresponding ECGI of RN for reporting.

It is highly preferred that mobile RN is when the composition information of ECGI is reported, the S1 interfaces between mobile anchor point can be based on Or X2 interface is reported, i.e., mobile anchor point receives the corresponding ECGI of described mobile RN that mobile RN is reported by S1 interfaces or X2 interface Composition information.

It is highly preferred that mobile RN reports the composition information of itself corresponding ECGI after can needing switching UE is detected, I.e. mobile anchor point receives the composition letter of the corresponding ECGI of mobile RN that mobile RN is reported after the UE for detecting management needs switching Breath.

In the preferred implementation one, the composition information of ECGI can be whole ECGI information, in the case, mobile RN is directly to report corresponding ECGI information to mobile anchor point.

It is highly preferred that the composition information of ECGI can also be the number of bits evidence in ECGI in addition to global Base Station Identification, In the case, mobile RN is to report number of bits evidence in corresponding ECGI in addition to global Base Station Identification to mobile anchor point, Namely last 8 bit in ECGI, by way of the number of bits evidence reported in ECGI in addition to global Base Station Identification, can The data volume for reporting effectively is reduced, the purpose of network transmission resource is saved so as to reach.If what mobile anchor point was received is to move Number of bits evidence in the ECGI that dynamic RN is reported in addition to global Base Station Identification, then mobile anchor point needs are further right according to itself Answer with mobile RN identicals whole world Base Station Identification and the number of bits evidence of reception, determine the corresponding ECGI of movement RN, I.e. itself corresponding and mobile RN identicals whole world Base Station Identification is combined with the number of bits evidence for receiving and obtains ECGI.

Wherein, if that mobile RN reports is complete ECGI, moving RN needs to obtain its from OAM systems corresponding ECGI。

The preferred implementation one of the corresponding ECGI of mobile RN is determined by above-mentioned mobile anchor point, mainly by mobile RN master The all or part of message for reporting its corresponding ECGI is moved, so that mobile anchor point is capable of determining that its each mobile RN difference is corresponding ECGI, is easy to be addressed mobile RN according to the handover request message for receiving.

Mobile anchor point determines the preferred implementation two of the corresponding ECGI of mobile RN

In the preferred implementation two, mobile anchor point determines the corresponding ECGI of mobile RN, is mainly divided by mobile anchor point Match somebody with somebody, i.e., mobile anchor point determines the corresponding ECGI of mobile RN according to itself corresponding and mobile RN identicals whole world Base Station Identification.

Specifically, mobile anchor point is corresponding according to itself and moves RN identicals whole world Base Station Identification, it is determined that mobile RN pairs After the ECGI for answering, in addition it is also necessary to which the ECGI that will further determine is respectively allocated to move RN accordingly, specifically, mobile anchor point When distributing ECGI to mobile RN, can by S1 interfaces or X2 interface, to mobile RN distribution determine it is corresponding with movement RN ECGI composition information.

It is highly preferred that when mobile anchor point is by S1 interfaces, to mobile RN distribution determine it is corresponding with movement RN During the composition information of ECGI, specifically response message (S1 Setup Response message), mobile management can be set up by S1 Entity MME configuration update messages (MME Configuration Update message) or special ECGI assignment messages, to the movement The composition information of the ECGI corresponding with movement RN that RN distribution is determined.

It is highly preferred that when mobile anchor point is by X2 interface, to mobile RN distribution determine it is corresponding with movement RN During ECGI, response message (X2 Setup Response message), base station configuration updating information (eNB can be set up by X2 Configuration Update message) or special ECGI assignment messages, determined to movement RN distribution with movement RN The composition information of corresponding ECGI.

In the preferred implementation two, the composition information of ECGI can be whole ECGI information, in the case, mobile Anchor point distributes the composition information of the ECGI corresponding with movement RN for determining by S1 interfaces or X2 interface to mobile RN, that is, move Dynamic anchor point distributes the ECGI corresponding with movement RN for determining by S1 interfaces or X2 interface to mobile RN.

It is highly preferred that the composition information of ECGI can also be the number of bits evidence in ECGI in addition to global Base Station Identification, In the case, mobile anchor point distributes the ECGI corresponding with movement RN for determining by S1 interfaces or X2 interface to mobile RN Composition information, i.e. mobile anchor point distributes determine corresponding with movement RN by S1 interfaces or X2 interface to mobile RN Number of bits evidence in ECGI in addition to global Base Station Identification, by movement RN further according to itself corresponding and mobile anchor Point identical whole world Base Station Identification and number of bits evidence determine ECGI.

The preferred implementation two of the corresponding ECGI of mobile RN is determined by above-mentioned mobile anchor point, mainly by mobile anchor point The corresponding ECGI of the mobile RN of distribution, so that mobile anchor point is capable of determining that each mobile RN distinguishes corresponding ECGI, are easy to basis to connect The handover request message of receipts is addressed to mobile RN.

Embodiment two

Addressing method in the cell switch process that the present embodiment two is provided for above-described embodiment one, gives several tools The addressing method implements process under body application scenarios.

In the application scenarios that the embodiment two is provided, the following two kinds is based primarily upon pre-configured：

1st, the global Base Station Identification for configuring mobile RN is identical with the global Base Station Identification of the mobile anchor point of ownership, in target During MME addressing mobile anchor points, MME can be addressed to unique mobile anchor point according to the global Base Station Identification of Target cell；Or

2nd, the TAI for configuring each mobile anchor point is different, and when target MME addresses mobile anchor point, MME can be according to mesh The TAI for marking cell is addressed to unique mobile anchor point.

Specific embodiment 1

The corresponding application scenarios of specific embodiment 1, are to be based on directly setting up S1 interfaces between mobile RN and mobile anchor point Situation, and mobile anchor point is based on ECGI addressing mobile RN, and the corresponding ECGI of mobile RN is configured by OAM.

Fig. 4 carries out cell configuration and the schematic flow sheet for addressing in showing the specific embodiment 1, specifically, main bag Include following steps：

Step 401, mobile RN are registered to after network, and operator's (specifically can be by OAM systems) is mobile RN configurations Global Base Station Identification be equal to ownership mobile anchor point global Base Station Identification.

Specifically, the corresponding ECGI of mobile RN refer to the ECGI that mobile RN is used in Uu interfaces, and mobile RN can be obtained from OAM Oneself is taken from the Uu mouthfuls of ECGI for using, and OAM needs to ensure as the ECGI of each movement RN distribution is different.

Preferably, the mobile anchor point that mobile RN can belong to relevant information (such as APN (Access Point Name, APN)) OAM is issued, it is that the ECGI for moving RN distribution possesses and mobile anchor point identical whole world base so as to contribute to OAM Station identifications.

S1 interfaces are set up between step 402, mobile RN and mobile anchor point, mobile RN leads to oneself in the Uu mouthfuls of ECGI for using Cross S1 interface notification mobile anchor points；Or, X2 interface is set up between mobile RN and mobile anchor point, mobile RN makes oneself at Uu mouthfuls ECGI notifies mobile anchor point by X2 interface.

More preferably, data group is distributed by the global Base Station Identification of 20 bits and the inside of base station of 8 bits because ECGI is general Into, therefore, mobile RN can by the 8 bit notification mobile anchor points ECGI of oneself behind, mobile anchor point can based on Mobile RN identicals whole world Base Station Identification, 8 bit datas that the global Base Station Identification is reported with mobile RN is combined and determines shifting The ECGI of dynamic RN, so as to reduce the data volume of transmission, saves network transmission resource.

More preferably, the ECGI of oneself just can be notified mobile anchor point by mobile RN in the scene that may have UE to switch, The ECGI of oneself is reported after detecting the presence of UE switching demands.

When step 403, UE need to be switched to mobile RN by S1, handover request message is sent to target MME, mesh Mark MME according to the global Base Station Identification of Target cell be addressed to the unique corresponding mobile anchor point of the global Base Station Identification, and to The mobile anchor point sends handover request message.
