Embodiment 1
Fig. 3 shows the method flow diagram according to the via node access network of the embodiment of the invention, and this method may further comprise the steps:
Step S302: via node receives the network connection failure indication from core net, and wherein, this network connection failure indication carries the indication information of re-accessing network;
Wherein, the network connection failure is designated as and receives in process or the running behind the via node access network that via node carries out network insertion;
Step S304: this via node is according to the indication information re-accessing network of above-mentioned re-accessing network;
For example: via node is confirmed the network phase that initiation inserts according to the indication information of re-accessing network, and this network phase comprises: with the user identity access network stage (being the phase I among Fig. 2) with via node identity access network stage (being the second stage among Fig. 2); This via node is according to the network phase re-accessing network after confirming.
Core net in the present embodiment is in RN access or running; Owing to reasons such as authentication or network planning decision-making changes; When causing RN to withdraw from current network, will send network connection failure indication, and withdraw from current network in order to indication RN and insert again to RN; RN receives this definite network phase of initiating access in indication back, carries out access network.This mode can confirm from which stage to insert again according to actual conditions.
Under some scenes, for the node that inserts with the relaying identity, even if be the possibility that also there is the second stage failed authentication in the equipment of non-malice.For example, through the new network planning, core-network side has been revised this access node and has no longer been had the via node function, the state of self and this access node does not also upgrade in time, and promptly access node thinks it self is RN, and core net thinks that access node is not RN.Access node is in the failure of second stage access network in this case, and this moment, access node should upgrade the configuration of self since the phase I re-accessing network through modes such as OAM downloads.And if access node begins re-accessing network from second stage, might cause repeatedly the access network failure, cause unnecessary access delay.For another example; Do not upgrade in time the information of the DeNB that can insert of via node; Make in the base station that the second stage via node inserts it is not the DeNB of service is provided or is not the base station that possesses the DeNB function for it; Cause via node in the failure of second stage access network, this moment, access node also can upgrade the information of the DeNB that can insert since the phase I re-accessing network through modes such as OAM downloads.And if access node begins re-accessing network from second stage, also possibly cause repeatedly the access network failure, cause unnecessary access delay.Therefore; During the via node re-accessing network of present embodiment; Via node was reasonably selected from phase I or from the second stage access network, reduced the delay of via node success access network, reduce via node blindly carrying out wrong access attempts and the network load that brings.
In the present embodiment, the indication information of above-mentioned re-accessing network comprises: information configured is upgraded in indication; Preferably, this information comprises one of following:
Indicate the state of this via node not possess the via node authority;
Indicate the host base station of the current access of this via node defective;
Wherein, defective the comprising of host base station of current access: this via node does not possess the authority that inserts current host base station; For example, the base station of via node access is not the DeNB that service is provided for it; And the current host base station that this via node inserts does not possess the via node of connection authority; For example, the base station that node inserts of continuing is not the base station that possesses the DeNB function.
Correspondingly, step S304 specifically can comprise: 1) via node is confirmed to comprise in the indication information of re-accessing network when information configured is upgraded in above-mentioned indication, confirms that the network phase of initiating to insert is with the user identity access network stage; 2) via node was initiated with the user identity access network stage, after connecting with the OAM server, to OAM download configuration data; 3) via node uses loading of configuration data to initiate with the via node identity access network stage.
Wherein, Via node can comprise to OAM download configuration data: via node upgrades the reason that information configured is confirmed the access network failure according to above-mentioned indication; Send a warning message to OAM, wherein, warning information carries the reason of via node access network failure; After OAM receives warning information, upgrade the configuration data of via node according to the reason of access network failure, wherein, configuration data comprises software configuration data and/or host's station list; Via node is downloaded the configuration data after OAM upgrades.
And for the underproof situation in host base station of the current access of via node, via node also can directly directly carry out network insertion from second stage (promptly with the via node identity access network stage) beginning; At this moment, via node confirms that according to the indication information of re-accessing network the host base station of current access is defective, confirms that then the network phase of initiating to insert is with the via node identity access network stage; Based on this, when above-mentioned via node was specifically realized according to the network phase re-accessing network after confirming, can comprise: via node was selected the base station except that the host base station of current access from host's station list; Via node as new host base station, is initiated the base station of selecting with the via node identity access network stage to new host base station.
Do not possess the situation that via node authority or via node do not possess the authority that inserts current host base station for the state of above-mentioned via node, via node receives before the network connection failure indication from core net, and this method also comprises:
When the Mobility Management Entity in the core net (MME) confirms that the state of via node does not possess via node authority or via node and do not possess the authority that inserts current host base station; Adhere to rejection signaling to the via node transmission; Adhere to rejection signaling and comprise above-mentioned network connection failure indication; At this moment, the network connection failure state that is designated as via node does not possess the via node authority or this via node does not possess the authority that inserts current host base station.
Preferably, above-mentioned network connection failure indication is arranged in the appointment cause value that adheres to rejection signaling or is arranged in the newly-increased cell that adheres to rejection signaling.
The current host base station of inserting for above-mentioned via node does not possess the situation that connects the via node authority, and via node receives before the network connection failure indication from core net, and this method also comprises:
When the Mobility Management Entity in the core net confirms that the current host base station of via node access does not possess the via node of connection authority; Discharge the context signaling of via node to the indication of current host base station; This context signaling packet includes network connection failure indication; At this moment, this network connection failure is designated as the current host base station that via node inserts and does not possess the via node of connection authority;
After this current host base station receives the context signaling, send release RRM RRC to via node and connect signaling, this release RRC connects signaling and comprises above-mentioned network connection failure indication.
Preferably, network connection failure indication is arranged on adheres to rejection signaling and discharges RRC and is connected in the appointment cause value of signaling, and perhaps this network connection failure is indicated to be arranged on and adhered to rejection signaling and be connected in the newly-increased cell of signaling with release RRC.
When the via node of present embodiment needs re-accessing network; Via node is confirmed from the phase I or from the second stage access network according to the indication of core net; Solved after the failure of RN access network the problem that can't connect with network; Simultaneously, this access way has reduced the delay of via node success access network, reduces that via node carries out access attempts blindly and the network load that brings.
Embodiment 2
The scene that present embodiment is described is that oneself state does not cause describing for ease in the failure of second stage access network because RN upgrades in time, and here still with RN sign access node, but this moment, this node possibly not possess the via node qualification.Referring to Fig. 4, the method for this via node access network may further comprise the steps:
Step S401:RN inserts core net EPC (being to insert the phase I) with the UE identity.RN connects (PDN connection through the data network of setting up this moment; Packet Data Network connection) inserts Internet; And obtain to be its OAM that serves (oam system) server address, and set up professional the connection with this server according to manufacturer configuration.After OAM carries out authentication to RN, according to local canned data and RN Location information this moment, be the necessary service data of RN configuration, for example RN allows host base station (DeNB) tabulation of access.
Step S402:RN is according to resulting DeNB tabulation among the step S401, the DeNB that selection can insert.Set up the RRC successful connection between RN and the DeNB, and set up in the process in the RRC connection, RN informs that the DeNB access node is a via node.RN carries own attach request (Attach Request) to EPC (core net) in the RRC signaling simultaneously.
Step S403:DeNB disposes according to own OAM, has perhaps obtained the information which MME can support the via node function setting up in the process of S1 mouth with the MME that is connected.DeNB is according to the information that obtains among the step S402, judges that institute's access node is a via node, and RN selects to support the MME of via node function for this reason.DeNB connects (UE associated S1 connection) and sets up flow process for this RN initiates special-purpose S1 to this MME, the attach request of RN is transmitted to this MME, and informs that in this process this access node of MME is a via node.
The access node that step S404:MME provides according to DeNB among the step S403 is the information of via node, need carry out authentication to this access node.Owing to some reasons, for example: the network planning of renewal no longer needs this RN to carry out the network coverage; Perhaps because hardware or software out-of-date no longer need use this RN.This RN is no longer allowed with the via node mode operation by network in the present embodiment, and this authenticating result confirms that access node does not possess the via node authority.
Step S405:MME sends and adheres to rejection signaling (ATTACH REJECT) (being equivalent to the network connection failure indication among the embodiment 1) to RN; Its state of indication RN is not legal via node in this signaling; For example, perhaps in this signaling, increase new cell through the specific EMM cause value (EMM Cause) in the signaling.
After step S406:RN receives Attach Reject message, break off with DeNB between RRC be connected.And know that from this message self has not possessed the via node authority, therefore need since the phase I re-accessing network, obtain the configuration data that upgrades with the said mode of step S401.
Alternatively, after RN successfully inserted the OAM server, RN provided the reference information of config update to OAM, and for example send a warning message (WARNING) gives OAM, and the reason of indication RN access network failure is that MME thinks that the state of RN no longer is a via node.
OAM is that RN upgrades configuration data, for example software upgrading.If after the Data Update, RN possesses the via node authority again, and the step after then can repeating step S402 is with via node identity access network.If after the Data Update, RN does not still possess the via node authority, and is then out of service.
The via node of present embodiment is behind the second stage access failure; Because of failure cause is self to dispose not possess the via node authority; Therefore confirm from the phase I access network, solved after the failure of RN access network the problem that can't connect with network, simultaneously; This access way has reduced the delay of via node success access network, reduces that via node carries out access attempts blindly and the network load that brings.
The scene that present embodiment is described is that the information of the DeNB that can insert because RN does not upgrade in time causes failing at the second stage access network.This embodiment is except that step S504 and step S506, and other steps are identical with embodiment 2, and referring to Fig. 5, the method for this via node access network may further comprise the steps:
Step S501:RN inserts core net EPC (being to insert the phase I) with the UE identity.RN connects (PDN connection through the data network of setting up this moment; Packet Data Network connection) inserts Internet; And obtain to be its OAM that serves (oam system) server address, and set up professional the connection with this server according to manufacturer configuration.After OAM carries out authentication to RN, according to local canned data and RN Location information this moment, be the necessary service data of RN configuration, for example RN allows host base station (DeNB) tabulation of access.
Step S502:RN is according to resulting DeNB tabulation among the step S501, the DeNB that selection can insert.Set up the RRC successful connection between RN and the DeNB, and set up in the process in the RRC connection, RN informs that the DeNB access node is a via node.RN carries own attach request (Attach Request) to EPC in the RRC signaling simultaneously.
Step S503:DeNB disposes according to own OAM, has perhaps obtained the information which MME can support the via node function setting up in the process of S1 mouth with the MME that is connected.DeNB is according to the information that obtains among the step S502, judges that institute's access node is a via node, and RN selects to support the MME of via node function for this reason.DeNB connects (UE associated S1 connection) and sets up flow process for this RN initiates special-purpose S1 to this MME, the attach request of RN is transmitted to this MME, and informs that in this process this access node of MME is a via node.
The access node that step S504:MME provides according to DeNB among the step S503 is the information of via node, need carry out authentication to this access node.But because the change of the network planning causes the selected DeNB of RN this moment no longer for it service to be provided.Therefore authenticating result confirms that access node does not possess the authority of DeNB access thus.
Step S505:MME sends and adheres to rejection signaling (ATTACH REJECT) (being equivalent to the network connection failure indication among the embodiment 1) to RN; Indication RN does not possess the authority that under this DeNB, inserts in this signaling, for example increases new cell through the specific EMM cause value (EMM Cause) in the signaling or in this signaling.
After step S506:RN receives Attach Reject message, break off with DeNB between RRC be connected.And from this message, know self not possessed the authority that this DeNB inserts down, therefore need since the phase I re-accessing network, obtain the configuration data that upgrades with the said mode of step S501.
Alternatively; After RN successfully inserts the OAM server; RN provides the reference information of config update to OAM; For example send a warning message (WARNING) to OAM, the reason of indication RN access network failure is that the DeNB that RN inserts is not the DeNB for this RN service, refers to that promptly this via node does not possess the authority of the current host of access base station.
OAM is that RN upgrades configuration data, for example new host's station list.RN is according to new tabulation, and the step after the repeating step S502 is with via node identity access network.
The via node of present embodiment is behind the second stage access failure; Because of failure cause is that the said via node of indication does not possess the authority that inserts current host base station; Therefore confirm from the phase I access network, solved after the failure of RN access network the problem that can't connect with network, simultaneously; This access way has reduced the delay of via node success access network, reduces that via node carries out access attempts blindly and the network load that brings.
Embodiment 4
The scene that present embodiment is described is that RN is with via node identity access network and operation, because the change of the network planning need break RN from network.Referring to Fig. 6, the method for this via node access network may further comprise the steps:
Step S601:RN inserts core net EPC (being to insert the phase I) with the UE identity.RN connects (PDN connection through the data network of setting up this moment; Packet Data Network connection) inserts Internet; And obtain to be its OAM that serves (oam system) server address, and set up professional the connection with this server according to manufacturer configuration.After OAM carries out authentication to RN, according to local canned data and RN Location information this moment, be the necessary service data of RN configuration, for example RN allows host base station (DeNB) tabulation of access.
Step S602:RN is according to resulting DeNB tabulation among the step S601, the DeNB that selection can insert.Set up the RRC successful connection between RN and the DeNB, and set up in the process in the RRC connection, RN informs that the DeNB access node is a via node.RN carries own attach request (Attach Request) to EPC in the RRC signaling simultaneously.
Step S603:DeNB disposes according to own OAM, has perhaps obtained the information which MME can support the via node function setting up in the process of S1 mouth with the MME that is connected.DeNB is according to the information that obtains among the step S602, judges that institute's access node is a via node, and RN selects to support the MME of via node function for this reason.DeNB connects (UE associated S1 connection) and sets up flow process for this RN initiates special-purpose S1 to this MME, the attach request of RN is transmitted to this MME, and informs that in this process this access node of MME is a via node.
The access node that step S604:MME provides according to DeNB among the step S603 is the information of via node, need carry out authentication and authentication success to this access node.MME RN for this reason selects to be positioned at this locality bag data gateway (PGW, Packet Data Network Gateway) on the DeNB.On this local PGW, set up PDN Connection for RN.MME also for this reason RN set up RAB (E-RAB, E-UTRAN Radio Access Bearer).RN sets up S1 and X2 interface with DeNB on this carries, and with the operation of via node identity, for the UE under its covering provides wireless access.
Step S605:RN worked after a period of time, had carried out the new network planning, and had not needed this RN to continue to provide service in this zone.According to new planning; MME is to the context (UE Context Release Commond) (being equivalent to the network connection failure indication among the embodiment 1) of DeNB indication release RN; This RN of notice DeNB no longer includes the authority of via node down at it in this signaling, for example increases new cell through the specific reasons value (Cause) in the signaling or in this signaling.
Step S606:DeNB break off with RN between RRC be connected (RRCConnectionRelease) signaling; And in this signaling, indicate RN under this DeNB, to no longer include the authority of via node, for example increase new cell through the specific reasons value (Cause) in the signaling or in this signaling.
Step S607:UE need since the phase I re-accessing network, obtain the configuration data that upgrades with the mode among the step S601.
Alternatively, after RN successfully inserted the OAM server, RN provided the reference information of config update to OAM, and for example send a warning message (WARNING) gives OAM, and the reason of indication RN access network failure is that the DeNB that RN inserts no longer provides service for RN.OAM is that RN upgrades configuration data, for example new host's station list.RN is according to new tabulation, and the step after the repeating step S602 is with via node identity access network.
The via node of present embodiment is behind the second stage access failure; Because of failure cause is that therefore the DeNB that inserts no longer confirms from the phase I access network for RN provides service (being that via node does not possess the authority that inserts current host base station); Solved after the failure of RN access network the problem that can't connect with network; Simultaneously, this access way has reduced the delay of via node success access network, reduces that via node carries out access attempts blindly and the network load that brings.
Embodiment 5
The scene that present embodiment is described is that the information of the DeNB that can insert because RN does not upgrade in time causes in the failure of second stage access network, i.e. the host base station of the current access of via node is defective.Wherein, the defective finger in host base station: via node does not possess the authority that inserts current host base station; For example, the base station of via node access is not the DeNB that service is provided for it; Perhaps, the current host base station of via node access does not possess the via node of connection authority; For example, the base station that node inserts of continuing is not the base station that possesses the DeNB function.
Present embodiment and embodiment 3 are basic identical; The difference part is; After via node in the present embodiment received the network connection failure indication of core-network side, the indication information of the re-accessing network in this indication comprised: indicate the host base station of the current access of this via node defective; At this moment, via node confirms that the network phase of initiating to insert is with via node identity access network stage, i.e. second stage; In the present embodiment; Via node can be selected the base station except that the host base station of this current access from host's station list; Initiate with the via node identity access network stage to new host base station as new host base station this base station that via node will be selected.
The via node of present embodiment is behind the second stage access failure; Because of failure cause is that via node does not possess the authority that inserts current host base station; Therefore confirm from the second stage access network, solved after the failure of RN access network the problem that can't connect with network, simultaneously; This access way has reduced the delay of via node success access network, reduces that via node carries out access attempts blindly and the network load that brings.
