Description
Technical field
The present invention relates to wireless communication technique, particularly relate to a kind of method and Home eNodeB, X2 gateway of X2 message informing.
Background technology
Home eNodeB is a kind of small-sized low power base station, private resource as private user is deployed in the private sites such as family, group, company or school, by the core net of the access in radio equipment connections such as cable, digital subscriber line (DigitalSubscriber Line is called for short DSL) or optical fiber to operator.The Main Function of Home eNodeB provides higher service rate to user, and reduce the cost used required for high-rate service, and the covering simultaneously making up existing distributed cellular wireless telecommunication system is not enough.The advantage of Home eNodeB comprises: low cost, (plug and play) easy to use, low power output, the expense saving operator's erection and base station maintenance, the optimization of solution in-door covering etc.
In Long Term Evolution (Long Term Evolution is called for short LTE) system, the network architecture schematic diagram at Home eNodeB (Home Evolved NodeB the is called for short HeNB) place of evolution, as shown in Figure 1.Terminal (User Equipment is called for short UE) under HeNB is the Home eNodeB Access Network (Home Evolved NodeB Access Network is called for short HeNBAN) based on existing air protocol access evolution.HeNBAN is femto gateway (Home EvolvedNodeB Gateway the is called for short HeNB GW) composition by HeNB and evolution.The function that HeNB supports and enhanced base station (evolved Node B is called for short eNB) are basically identical, only connect a community under a HeNB.HeNB GW is optional network element.The major function of HeNB GW is: the S1 message that relaying UE is relevant, the S1 message that the non-UE that terminates is relevant, for UE optional m igration management entity (Mobility Management Entity is called for short MME) etc. in attaching process.S1 interface is the wireless access network of eUTRAN(evolution) and CN Node(core net node) between interface, HeNB can be directly connected to block core (the Evolved Packet Core of evolution by S1 interface, be called for short EPC), wherein HeNB is connected to gateway (Serving Gateway by S1-U interface, be called for short S-GW), HeNB is connected to MME by S1-MME interface.HeNB also can be connected to EPC by HeNB GW, and wherein S1-U interface can terminate in HeNB GW, or terminates in EPC, and S1-MME interface is through HeNB GW to EPC.EPC network element comprises MME and S-GW.MME carries the correlation function such as bearer management, mobile management.S-GW carries the functions such as the data route in user face.In addition, home base station management system (the HeNB Management System of the evolution in Fig. 1, be called for short HeMS) maintenance and management is carried out to HeNB, according to requirement configuration and the control HeNB of operator, wherein most importantly for HeNB realizes configuration feature, the content of configuration comprises the examining of positional information, the parameter of HeNB, the parameter of core net, wireless access network (Radio Access Network, be called for short RAN) parameter and the parameter of wireless frequency (Radio Frequency, be called for short RF).The function that safety in security gateway (Security Gateway is called for short SeGW) network enabled is relevant.
HeNB is only for specific user provides service, and the concept therefore having introduced closed member's group (ClosedSubscriber Group is called for short CSG) performs access control.Each HeNB has specific CSG attribute, comprises closed member and organizes mark (CSG Identity is called for short CSG ID) and access module.Here for HeNB defines three kinds of community access modules (Cell Access Mode): close (Close) pattern, the closed member composition person only having corresponding CSG ID to identify just can access; Mixing (Hybrid) pattern, allow all UE accesses, but the closed member composition person having corresponding CSG ID to identify enjoys higher priority; Open (Open) pattern, allows all UE accesses.
Third generation partner program (3rd Generation Partnership Project, be called for short 3GPP) permit setting up the direct X2 interface for switching object under being intended to following scene when Release10 and Release11: between the HeNB of eNB and open pattern, between the HeNB of eNB and hybrid pattern, the HeNB of source closed pattern is to target eNB, between the HeNB of HeNB and the open/hybrid pattern of open pattern, the HeNB of HeNB to the target open/hybrid pattern of source closed pattern, there is the HeNB of HeNB to the target closed pattern of the source hybrid/closed pattern of identical PLMN ID and CSG ID.Can, by being that direct X2 connects, also can be connected by the indirect X2 of the new functional entity X2 gateway (X2Gateway is called for short X2GW) of similar HeNB GW between eNB and HeNB, between HeNB.In the discussion process introducing X2GW scheme, wireless network layer (the Radio Network Layer of source based target side, be called for short RNL) mark (Identity, be called for short ID) route X2 message, (H) eNB uses new registration message to come set up in X2GW and preserve RNL ID and transport network layer (Transport NetworkLayer when start, be called for short TNL) matching relationship of address, the IP address configuration of X2GW is to HeNB, eNB is by the mode of configuration or known that by TNL address discovery process the scheme of IP address of X2GW is as the candidate scheme of X2GW.In this candidate scheme, there are the following problems: the IP address due to X2GW configures to HeNB, after therefore HeNB mono-start powers on, new registration message namely can be used to set up in X2GW and preserve the matching relationship of RNL ID and TNL address.When eNB to obtain the TNL address of X2GW by the process of TNL address discovery time, or after eNB start powers on also not when the X2GW being configured with IP address registers, if also determine after HeNB has found the community that eNB serves that will set up indirect X2 with this eNB is connected, HeNB sends the X2 identified with the RNL ID of target eNB and sets up request message to X2GW, but because now X2GW place does not preserve the RNL ID of eNB and the matching relationship of TNL address, X2GW cannot set up request message to target eNB by route X2.In order to solve this problem, have about knowing that at HeNB X2GW cannot after route X2 sets up request message to target eNB, HeNB is suggested in the scheme of the RNL ID and TNL address that send to the X2 of X2GW to set up to carry eNB in request message, registration message or registration update message.HeNB how to know X2GW be due to there is no the RNL ID of target eNB and TNL matching addresses relation and cannot route X2 to set up request message to target eNB be the problem to be solved in the present invention.
When HeNB with HeNB or eNB that he finds be connected on different X2GW time, HeNB with find HeNB or eNB between be do not set up indirect X2 interface by X2GW.How HeNB knows that HeNB or eNB with finding is not connected on same X2GW, thus the expense of playing drinking games in a large number that the indirectly X2 avoiding HeNB constantly to attempt HeNB or eNB being established to discovery connects and causes is the problem to be solved in the present invention.
ENB and HeNB between, HeNB and HeNB between can not set up simultaneously direct X2 interface and by X2GW set up agency X2 interface.Also namely, eNB and HeNB between, HeNB between otherwise set up direct X2 interface, otherwise set up the X2 interface acted on behalf of by X2GW.As shown in Figure 2, HeNB2 with HeNB3 intention is connected by the X2 of X2GW foundation agency, and the X2 that eNB1 with HeNB2 intention sets up agency by X2GW is connected, but eNB1 with HeNB3 is intended to set up direct X2 to be connected.The IP address of X2GW configures to HeNB, and after therefore HeNB2 and HeNB3 mono-start powers on, registration message that namely can be new carrys out the matching relationship setting up and preserve RNL ID and TNL address in X2GW.Meanwhile, when the IP address of X2GW be configuration to eNB time, after eNB mono-start powers on, registration message that namely can be new carrys out the matching relationship setting up and preserve RNL ID and TNL address in X2GW.Will set up direct X2 to connect between eNB1 and HeNB3, the problem reducing TNL address discovery process quantity to be considered when considering design X2GW scheme, so how HeNB3 gets the TNL address of eNB1, thus the quantity effectively reducing TNL address discovery process is also the problem that this patent will solve.

The method of the embodiment of the present invention HeNB can be made to know X2GW cannot set up the reason of request message to target eNB by route X2, thus to take appropriate measures.
Embodiment one
In the present embodiment, eNB obtains the TNL address of X2GW by the process of TNL address discovery, X2GW receive set up request message from the X2 of the RNL ID with target eNB of HeNB time, not having to find to store the RNL ID of target eNB and the matching relationship of TNL address from being in, therefore cannot set up request message to target eNB by route X2.
X2GW carries new cause value in the X2 message sending to HeNB, such as " match information is unavailable ", " unknowable destination address ", " route is not supported " etc., make source HeNB hold and know that X2GW cannot set up request message to target eNB end by route X2 owing to not having the RNL ID of target eNB and TNL matching addresses relation.This X2 message can be that X2 sets up failed message.
The RNL ID of target eNB and the TNL address of target eNB that obtained by TNL address discovery process can be sent to X2GW by source HeNB in subsequent process, such as, HeNB is made to set up request message sending to the X2 of X2GW, RNLID and the TNL address of eNB is carried in registration message or registration update message, thus make the SCTP(STREAM CONTROLTRANSMISSION PROTOCOL of X2GW foundation and eNB, SCTP) connect, and make X2GW preserve the RNL ID of eNB and the matching relationship of TNL address, thus ensure that follow-up X2 sets up request message and is properly routed to target eNB.
Fig. 3 is the schematic flow sheet of the present embodiment, as shown in Figure 3, comprises the following steps:
After the IP address of step 101:X2GW is configuration start powers on to HeNB, HeNB mono-, carry out by register flow path the matching relationship setting up and preserve RNL ID and TNL address in X2GW.
After step 102:HeNB finds the community of eNB service, determine that the indirect X2 that will be established to eNB connects.
The X2 that step 103:HeNB sends with the RNL ID of target eNB sets up request message to X2GW.
Step 104: now X2GW place does not preserve the RNL ID of eNB and the matching relationship of TNL address, X2GW cannot set up request message to target eNB by route X2, X2GW returns X2 message to HeNB, new cause value is carried in the X2 message returned, such as " match information is unavailable ", " unknowable destination address ", " route is not supported " etc., source HeNB is known, and X2GW is owing to not having the RNL ID of target eNB and TNL matching addresses relation and cannot set up request message to target eNB by route X2.This X2 message can be that X2 sets up failed message.
Step 105:HeNB initiates the TNL address that TNL address discovery process obtains eNB.
Step 106: by step 104, source HeNB knows that X2GW after route X2 sets up request message to target eNB, cannot set up the TNL address of the RNL ID carrying eNB in request message, registration message or registration update message and the eNB obtained in step 105 sending to the X2 of X2GW.X2GW, after the RNL ID getting eNB and TNL address, can preserve the RNL ID of eNB and the matching relationship of TNL address, and the SCTP set up between X2GW and eNB connects.
The X2 that step 107:HeNB sends with the RNL ID of target eNB sets up request message to X2GW.X2 is set up request message according to the RNL ID of eNB stored and the matching relationship of TNL address and is routed to corresponding target eNB place by X2GW.
Step 108:eNB replys and sets up response message with the X2 of the RNL ID of target HeNB and according to the RNL ID of HeNB of storage and the matching relationship of TNL address, X2 is set up response message to X2GW, X2GW and be routed to corresponding target HeNB place.
Embodiment two
When HeNB1 is registered on X2GW1, HeNB2 or eNB2 is registered in X2GW2, and under this scene, HeNB1 is with being do not set up indirectly X2 interface by X2GW1 between HeNB2 or eNB2.
X2GW carries new cause value in the X2 message sending to HeNB, and such as " not under same X2GW " etc., the source HeNB of making knows that source HeNB is not connected on same X2GW with newfound HeNB or eNB.This X2 message can be that X2 sets up failed message.The HeNB follow-up indirectly X2 being established to newfound HeNB or eNB that can not reattempt in source connects, thus avoids the expense of X2 signaling unnecessary in a large number.
Fig. 4 is the schematic flow sheet of the present embodiment, as shown in Figure 4, comprises the following steps:
The IP address of step 201:X2GW1 configures to HeNB1, after start powers on, comes set up in X2GW1 and preserve the RNL ID of HeNB1 and the matching relationship of TNL address by register flow path.
The IP address of step 202:X2GW2 configures to HeNB2 or eNB2, after start powers on, comes set up in X2GW2 and preserve the RNL ID of HeNB2 or eNB2 and the matching relationship of TNL address by register flow path.
After step 203:HeNB1 finds the community of HeNB2 or eNB2 service, determine that the indirect X2 that will be established to HeNB2 or eNB2 connects.
The X2 that step 204:HeNB1 sends with the RNL ID of target HeNB2 or eNB2 sets up request message to X2GW1.
Step 205: due to the matching relationship of the matching relationship of RNL ID and TNL address that do not have HeNB2 in X2GW1 or the RNL ID of eNB2 and TNL address, X2GW1 returns X2 message to HeNB1, new cause value can be carried, such as " not under same X2GW " etc. in the X2 message returned.This X2 message can be that X2 sets up failed message.
After HeNB1 receives the X2 message with cause specific value, can know that HeNB1 is not connected on same X2GW with HeNB2 or eNB2, the follow-up HeNB1 that works as finds the community that HeNB2 or eNB2 serves again, and time the indirect X2 determining to be established to HeNB2 or eNB2 connects, the X2 being initiated to X2GW1 again can be avoided to set up request message.
Embodiment three
In this embodiment, suppose to be kept at HeNB place to, HeNB with HeNB to setting up the mode (direct X2 connects or X2 connects indirectly) that X2 is connected about eNB with HeNB.
When source HeNB determines according to its X2 connected mode of preserving the direct X2 connection being established to target eNB time, the HeNB request of carrying in the X2 message sending to target eNB in source returns the indication information of the TNL address of target eNB, and this X2 message can be that X2 sets up request message.After X2GW receives this X2 message, if there have been the RNL ID of target eNB and the matching relationship of TNL address in X2GW place, X2GW not according to the matching relationship of the RNL ID of target eNB stored and TNL address by this X2 Message routing to corresponding target eNB, but send X2 message to source HeNB, and in this X2 message, carry the TNL address of target eNB, this X2 message can be that X2 sets up failed message, thus makes follow-up source HeNB directly be initiated to the direct X2 establishment of connection of target eNB.
Fig. 5 is the schematic flow sheet of the present embodiment, as shown in Figure 5, comprises the following steps:
After the IP address of step 301:X2GW is configuration start powers on to HeNB2, HeNB2 mono-, come set up in X2GW and preserve the RNL ID of HeNB2 and the matching relationship of TNL address by register flow path.
After the IP address of step 302:X2GW is configuration start powers on to HeNB3, HeNB3 mono-, come set up in X2GW and preserve the RNL ID of HeNB3 and the matching relationship of TNL address by register flow path.
Step 303: if the IP address of X2GW configures to eNB1, after so eNB1 mono-start powers on, sets up in X2GW and preserve the RNL ID of eNB1 and the matching relationship of TNL address by register flow path.ENB1 also can obtain the TNL address of X2GW by TNL address discovery process, namely step 303 is omitted, and in X2GW being so does not after step 302 have the RNL ID of eNB1 and TNL matching addresses relation.
After step 304:HeNB3 finds the community of eNB1 service, according to the mode of the X2 connection that HeNB3 place stores, the direct X2 that be established to eNB1 connects.
Step 305:HeNB3 sends with the X2 message of the RNL ID of target eNB 1 to X2GW.The request of also carrying in this X2 message returns the indication information of the TNL address of eNB1.This X2 message can be that X2 sets up request message.
Step 306: if X2GW saves RNL ID and the TNL matching addresses relation of eNB1 in step 303, so when X2GW receives after the X2 returning the indication information of the TNL address of eNB1 with request sets up request message, X2 is not set up request message according to the RNL ID of eNB1 stored and the matching relationship of TNL address and is routed to corresponding target eNB 1 by X2GW, but reply X2 message to HeNB3, this message can be that X2 sets up failed message, and the TNL address that eNB1 preserves when X2GW place registers is returned to HeNB3 in this X2 message.
If step 303 is not carried out, X2GW does not preserve RNL ID and the TNL matching addresses relation of eNB1, so when X2GW receives after the X2 returning the indication information of the TNL address of eNB1 with request sets up request message, return X2 message to HeNB3, this message can be that X2 sets up failed message, does not carry the TNL address information of eNB1 in this message.HeNB3 upon receiving the message, can initiate TNL address discovery process to obtain the TNL address of eNB1.
After step 307:HeNB3 obtains the TNL address of eNB1, set up and be connected with the direct X2 of eNB1.
After step 308:HeNB2 finds the community of eNB1 service, according to the mode of the X2 connection that HeNB2 place stores, the indirect X2 that be established to eNB1 connects.
The X2 that step 309:HeNB2 sends with the RNL ID of target eNB 1 sets up request message to X2GW, if X2GW place stores the RNL ID of eNB1 and the matching relationship of TNL address, so X2 is set up request message according to the RNL ID of eNB1 stored and the matching relationship of TNL address and is routed to corresponding target eNB 1 by X2GW.ENB1 replys and sets up response message with the X2 of the RNLID of target HeNB2 and according to the RNL ID of HeNB2 of storage and the matching relationship of TNL address, X2 is set up response message to X2GW, X2GW and be routed to corresponding target HeNB2.
