Specific embodiment

The exemplary embodiment for embodying feature of present invention and advantage will describe in detail in the following description.It should be understood that The present invention can have various variations in different embodiments, neither depart from the scope of the present invention, and theory therein Bright and diagram inherently is illustrated as being used, rather than to limit the present invention.

As previously described, for LTE cluster communication, any base station is all possibly into fail soft state, i.e. itself and core S1 link between net is abnormal, at this point, the base station only can provide service for the user terminal for including in its corresponding cell, and And there is passing through X2 link communication between other adjacent base stations, but due to S1 link it is abnormal and can not be with core Network Communication, to communicate successful probability and communication range substantially reduces.

In consideration of it, special propose a kind of restoration methods of base station communication under fail soft, to enter fail soft in base station The expansion for guaranteeing to communicate successful probability and communication range still is able under the premise of state, to ensure that base station is communicated Reliability.

In one embodiment, specifically, this method is as shown in Figure 1, comprising:

Step S110 receives the fail soft station list that core net returns and/or adjacent base station is sent, receives Fail soft station list includes: the corresponding base station path information of the identification information and identification information of fail soft base station.

Base station will receive fail soft station list in broadband cluster system, and fail soft station list is used to be broadband In group system this base station or it is other provided into the recovery communicated in the base station of fail soft state required for base station road The network address of diameter or target BS.

Received fail soft station list is to be diffused into this base station by core net and/or adjacent base station, therefore, therefore Had recorded in barrier reduction station list its diffusion by way of the identification information of fail soft base station, core net identification information, And the identification information of each fail soft base station has corresponding base station path information.

Wherein, the path that adjacent base station is reached from corresponding fail soft base station is had recorded in base station path information.

On the one hand, since this base station enters fail soft state, in the obtained fail soft station list of core net Have recorded this base station, therefore, core net will each adjacent base station to this base station return fail soft station list, in order to enter This base station of fail soft state can restore the communication between core net or other base stations；On the other hand, any to enter The fail soft station list of the base station building of fail soft state is spread in entire broadband cluster system, therefore, This base station can receive the fail soft station list of adjacent base station diffusion, at this point, interrupting this base station of communication by received Fail soft station list can at least know its adjacent base station, to restore its communication between adjacent base station.

Need it is clear that, fail soft station list is expanded after being constructed by any base station into fail soft state It dissipates, the diffuseness termination carried out is in core net.

Step S130 updates identification information in fail soft station list when base station itself enters fail soft state Corresponding base station path information and the identification information for adding itself.

If base station itself enters fail soft state, in received fail soft station list, to each base Routing information of standing is updated, and the identification information of itself is added.

Step S150, storage and diffusion fail soft station list.

After the update for completing fail soft station list, this fail soft station list will be stored and spread.One Aspect realizes the communication of this base station by the fail soft station list of progress, on the other hand, passes through the fail soft of progress What base station had little time spreads the maintenance to realize fail soft station list, in order to obtain final fail soft base station.

Step S170 restores the communication of this base station by the fail soft station list of storage.

This base station receives fail soft station list, and required base can be got from fail soft station list It stands routing information, and then restores to communicate according to base station path provided by base station path information.

, and then also can not be real under the control of core net for example, though this base station can not be by S1 link and core network communications Its existing communication between other base stations.But this base station according in fail soft station list base station path information establish with X2 link between adjacent base station, thus by adjacent base station and core network communications, and realize under the action of core net and its Communication between its base station.

This base station is successfully realized logical with other base stations and/or core net by communication recovery process as described above Letter, even and if then into fail soft state, various communication services can also be gone on smoothly, and for each use under this base station For the terminal of family, calling and response between other user terminals are realized in the service for still being able to provide by this base station.

In one embodiment, as shown in Fig. 2, method as described above further include:

Step S210, base station obtain the identification information of itself when entering fail soft state.

Identification information is used for unique identification base station or core net.The identification information of base station includes Base Station Identification (base station IDs) And/or the network address (base station IP) where base station；The identification information of core net includes core network identifier.

When any base station enters fail soft state in broadband cluster system, the acquisition of identification information will be all triggered, with right Base station enters fail soft state and carries out quick response.

Step S230 constructs fail soft station list according to identification information.

Fail soft station list is constructed into the base station of fail soft state in broadband cluster system, the failure of building is weak Change the identification information that station list includes at least this base station,

Therefore, although fail soft station list has only included the identification information of this base station at building, and still, failure is weak Change station list corresponding base station path information can be constantly updated by broadcast algorithm, and record by way of fail soft state Under base station.

It should be noted that the identification information for including in fail soft station list enters fail soft state for recording Base station, further, if including network address in fail soft station list identification information, in network address Under the action of the identification information be also used for realizing the recovery that communicates in the base station for entering fail soft state.

Further, in addition to the identification information of this base station in the building of fail soft station list, base station can also be constructed Routing information, and according to the base station path information of the corresponding storage building of identification information in fail soft station list.

Wherein, the base station path information of building can be sky, in the diffusion to weaken station list to consequent malfunction constantly more Newly, and then the base station path information being consistent with diffusion path is obtained；On the other hand, the base station path information of building can also only include The Base Station Identification of this base station, the base station of subsequent diffusion institute's approach or core net can constantly improve base station path information herein.

But which kind of form is the base station path information no matter constructed be, is all to be marked to reach it using this base station as source base station Its base station or the path of core net.

Step S250, spread fail soft station list, fail soft station list by diffusion by way of base station or core Heart net updates self-contained base station path information.

After constructing fail soft station list, arranged to adjacent base station or core net diffusion fail soft base station Table so that fail soft station list is spread in broadband cluster system, and then passes through each base station and core in broadband cluster system Heart net safeguards fail soft station list.

Specifically, corresponding range of scatter expands constantly with the diffusion of fail soft station list, by way of appoint Meaning base station or core net all updates base station path information to received fail soft station list and then to continue failure weak Change the diffusion of station list.

Wherein, the update of base station path information is according into fail soft station list in fail soft station list The base station or core net that various base station path information flags are passed through.Base station path information be it is corresponding with identification information, because This, base station path information has recorded the path between the corresponding base station of identification information and other base stations or core net.

It should be noted that the diffusion of fail soft station list refers to sending to all adjacent base stations or core net Fail soft station list, if the fail soft station list sent is received from an adjacent base station, institute in the updated The diffusion of progress is to the other adjacent base stations or core other than the aforementioned adjacent base station for sending fail soft station list Net sends updated fail soft station list.

Method as described above is the embodiment for running on the base station that one enters fail soft state, broadband cluster system The building and diffusion that fail soft station list can be all carried out when any base station enters fail soft state in system, can also lead to Received fail soft station list is crossed to restore to communicate.

In one embodiment, as shown in figure 3, after step S130, this method further include:

Step S310, obtains the base station user table of itself, and user present in the cell of base station user table record control is whole End.

Broadband cluster system includes the user terminal of core net, base station and the cell positioned at base station control, and each base station is all One or more cell is controlled, to provide service for the user terminal in cell.Base station user table has recorded base station control Cell present in user terminal.

Base station user table is stored in fail soft station list, and is associated with the identification information of itself by step S330.

The storage of base station user table is carried out in fail soft station list, and the base station user table of storage is made to be associated with mark Know information.Therefore, by fail soft station list, it can either know the road for restoring communication into the base station of fail soft state Diameter can also know which user terminal interrupts communication as base station enters fail soft state, so that these are interrupted The user terminal of communication can also initiate to call or carry out response.

Further, in one embodiment, target BS is fail soft base station, as shown in figure 4, step S170 packet It includes:

Step S171 receives the calling that user terminal is initiated, right in received fail soft station list according to calling Base station user table carries out calling and searches called user terminal.

Therefore this base station can still can when entering fail soft state with user terminal communication in the cell of control Enough receive obtains the calling that user terminal is initiated in cell, if the called user terminal of this calling also is located in the cell, This base station still is able to the communication established between the user terminal and called user terminal of initiating calling.

But if called user terminal is not on the cell, this base station is right in the response carried out to calling The base station user table stored in fail soft station list carries out calling lookup, that is, calling is found out and currently received calling Corresponding called user terminal.

Step S172, it is associated according to base station user table where called user terminal when lookup obtains called user terminal Identification information obtains target BS；

Base station user list where obtained called user terminal obtains is searched by calling, and then thus base station user arranges Being associated between table and identification information obtains identification information, and the base station that this identification information is identified is to respond call setup and quilt It is the target BS communicated between user terminal.

Called user terminal is located in the cell of target BS control.

Step S173 obtains corresponding base station path according to the identification information of base station itself in fail soft station list Information, and base station path is extracted in base station path information according to target BS.

As previously described, fail soft station list identification information is also right other than with base station user list association Should be in base station path information, therefore, base station user list where determining called user terminal simultaneously obtains associated mark letter After breath, corresponding base station path information will be obtained.Obtained base station path information restores communication for this base station, to initiate to exhale The user terminal cried is established and called user terminal.

Specifically, in obtained base station path information, using this base station as source base station, according to source base station and target BS into Row path extraction, to obtain that the path communicated between this base station and target BS is marked.

Step S175 establishes link according to base station path, restore with called user terminal communication between the base stations.

The X2 link between base station can be established, according to base station path to restore to be communicated between this base station and target BS Path, and then realize the communication between any user terminal and called user terminal.

By process as described above, so that also being capable of smooth its user terminal of realization into the base station of fail soft state With other user terminals, the communication between user terminal under the base station of even other fail soft states, for user's end For end, fail-soft influence is shielded.

Process as described above is applied to where base station where the user terminal for initiating calling and called user terminal Base station is under the scene of fail soft state, and in one embodiment, this scene can be the scene of core net failure.Example Such as, core net failure and cause all base stations in broadband cluster system to enter fail soft state.

In one embodiment, core net and the base station where called user terminal are not broken down, as shown in figure 5, Method as described above further include:

Step S410 obtains corresponding base according to the identification information of base station itself in received fail soft station list It stands routing information.

During receiving the calling of user terminal initiation and carrying out calling lookup in fail soft base station, if do not had Calling searches and obtains corresponding called user terminal, then illustrates the base that called user terminal is not present under fail soft state In controlled cell of standing, need to page the cell of other base stations control under the control of core net.Therefore, exist first Base station path information corresponding to itself identification information is obtained in received fail soft station list.

Step S430 is the base station path of core net by base station path information extraction purpose.

Using this base station as source base station, extract purpose be core net base station path, that is, the base station path extracted with This base station is starting, is the base station path terminated with target BS.

Step S450 establishes the link between core net according to base station path, restores the communication between core net.

In this scenario, the link down between this base station and core net, but core net is still up, therefore will The link between this base station and core net is established by the base station path of extraction.

Step S470 carries out the communication between user terminal and called user terminal by core net.

Called user terminal is searched out in the cell that other base stations control by core net, and then establishes user terminal and quilt Cry the communication between user terminal.Wherein, the base station where called user terminal is a certain base for not entering fail soft state It stands.

Base station where process as described above is applied to the user terminal for initiating calling enters fail soft state, and core In the scene that base station where net and called user terminal operates normally.

In one embodiment, identification information includes network address, as shown in fig. 6, method as described above further include:

Step S510, after obtaining target BS according to the associated identification information of base station user table where called user terminal, The network address of target BS is obtained from the identification information of target BS.

As previously described, identification information further comprises network address other than including Base Station Identification.In this embodiment In, base station path information is corresponding with Base Station Identification, and base station user list is also associated with Base Station Identification.

After this base station enters fail soft state, the corresponding target BS of response calling is obtained by calling to search, i.e., Base Station Identification corresponding to target BS is obtained, at this point, by corresponding network address is obtained by the identification information at place.

Step S530 is communicated by the network address of target BS with target BS, judges whether communication succeeds, if It is then to enter step S550, if it has not, then entering step S170.

Communication request message is initiated according to the network address of target BS, with the communication between foundation and target BS.Such as This base station of fruit is communicated successfully by the network address of target BS with target BS, then can directly carry out user terminal and called use Communication between the terminal of family；If this base station is communicated by the network address of target BS with target BS unsuccessful, need Pass through the communication between this base station of base station path Information recovering and target BS.

Step S550 carries out the communication between user terminal and called user terminal by target BS.

By process as described above, so that this base station into fail soft state is preferentially led to using network address Letter, and base station path information is then used as this base station to restore the alternative means communicated, it is a variety of for the communication recovery of this base station The presence of recovery ways ensure that the robustness of communication.

In one embodiment, identification information includes Base Station Identification, and this method is as shown in Figure 7, further includes:

Step S610, when receiving the fail soft station list of adjacent base station transmission, in fail soft station list The Base Station Identification of itself is added to base station path information, and stores the identification information of itself.

Base station path information includes Base Station Identification and/or core network identifier, wherein it is special that core network identifier can be used as one Base Station Identification.In other words, base station path information sequentially record its diffusion by way of each base station and core net, this record is logical Base Station Identification is crossed to realize.

Any fail soft station list is all the building when base station enters fail soft state, and content is by diffusing into Row updates, and the diffusion and update that carry out are terminated at core net.In other words, core net is for being diffused into the former of its own Barrier reduction station list, will carry out the update of each base station path information in fail soft station list, i.e., in base station path information In sequentially add core network identifier, and will itself be to make a special base station accordingly to be marked in fail soft station list Know the addition of information and base station path information, i.e. addition core network identifier, building is believed with the associated base station path of core network identifier Breath.

Wherein, base station path information, which is used to record, returns to base station corresponding to the base station of a fail soft state as core net Path.

Core net will store this fail soft base after the update for completing fail soft station list as described above It stands list, in order to restore to communicate with any base station into fail soft state.

At the same time, core net will also be according to the Base Station Identification and corresponding base station recorded in this fail soft station list Routing information returns to this fail soft station list to the base station under each fail soft state, so that each fail soft state Under base station save core net return fail soft station list.

By this process, the base station of fail soft state is enabled to save fail soft station list the most comprehensive, Think that it restores communication and provides safeguard, and due to handling the core net base station special as one, be more convenient for The recovery communicated between core net.

This base station in addition to building fail soft station list and is spread under fail soft state, and reception is returned by core net Fail soft station list except, can also receive fail soft station list transmitted by adjacent base station.

It is different from the fail soft station list of core net return, this fail soft station list is in diffusion process In, this base station be in diffusion process by way of a base station, in the case, the Base Station Identification for adding itself is added to each base station Routing information, and the identification information of itself is stored in this fail soft station list, in order in subsequent diffusion process This base station is obtained to other base stations or the base station path information of core net.

Step S630 obtains the base station user table of itself, and base station user table is stored in fail soft station list, and with The identification information association of itself.

As shown in figure 8, the base station user table of this base station dynamic generation itself, as previously described, the base station of this base station itself User's table with corresponding identification information associated storage in fail soft station list, with facilitate other base stations can by this therefore Barrier reduction station list finds the user terminal stored under the cell that this base station controls.

Specifically, any base station is serviced for the user terminal offer in its coverage area, i.e. cell, therefore, Mostly there is multiple user terminals for the cell that any base station is controlled, for fail soft station list, record into While entering identification information corresponding to the base station of fail soft state, also by the associated base station user table of dynamic generation, base station is used Family table has recorded into user terminal present in the base station of fail soft state.

The fail soft station list for completing the storage of base station user table will continue to spread, and be stored in this base station.

By process as described above, even if so that this base station into fail soft state, also can be place broadband collection Other base station maintenance fail soft station lists into fail soft state in group's system, and it is not limited in its own failure The building of station list is weakened, and then greatly improves the robustness communicated in broadband cluster system.

Further, in the present embodiment, this method is as shown in Figure 9, further includes:

Step S710 judges that diffusion times corresponding to the fail soft station list of the adjacent base station received transmission are It is no to reach pre-set limit, if it has, then S730 is entered step, if it has not, then entering step S610.

Diffusion times are for controlling diffusion of the fail soft station list in broadband cluster system.Fail soft base station column Base station or core net of the indicator for approach in the diffusion of each basestation marker into fail soft state recorded, so as to Path required for any base station marked or core net is reached in providing the base station that this enters fail soft state, it is still, right It is excessive in hop count, such as hop count has exceeded the path of pre-set limit and will be disabled, therefore, it is necessary to pass through diffusion times to carry out Control.In actual operation, numerical value corresponding to diffusion times will be determined according to specific networking configuring condition.

In one embodiment, it when constructing fail soft station list, will configure hop counter, and carried out In the diffusion of fail soft station list, hop counter and fail soft station list are diffused together, as failure is weak Each jump set that change station list is passed through is defeated, and row updates when will all trigger hop counter, for example, every by hop count when a jump Numerical value in device carries out subtracting operation certainly, and the initial value of hop counter is pre-set limit.

It is diffused the control of number by hop counter, if numerical value corresponding to hop counter is 0, illustrates to spread Number has reached pre-set limit, therefore, should abandon fail soft station list.

Step S730 abandons fail soft station list.

By process as described above, by effective guarantee fail soft station list base station path information it is effective Property so that the communication recovery realized by fail soft station list can with base station communication needs at any time into Row.

In another embodiment, the base station for receiving fail soft station list is not broken down, after step S110, such as Shown in Figure 10, method as described above further include:

Step S810 carries out the update of base station path information in fail soft station list according to the identification information of itself.

In the diffusion of fail soft station list, base station can all receive fail soft station list, if base station is not sent out Raw failure, at this point, by each base station path information is carried out in fail soft station list more according to the identification information of itself first Newly, to mark this base station in each base station path information.

It should be noted that carrying out received base station to the fail soft station list of diffusion will be energy in the present embodiment It is enough normally carried out communication, does not enter the base station of fail soft state.

Step S830 spreads the fail soft station list of update.

The fail soft station list updated to adjacent base station or core net diffusion.Specifically, weak if receiving failure The base station for changing station list is not in fail soft state, then its S1 link between core net is normal, can dock The fail soft station list of receipts is transmitted separately to core net and adjacent base station after updating.

By this process, the update and expansion for being arbitrarily normally carried out fail soft station list in the base station of communication are completed It dissipates, thus will ensure the maintenance of Arbitrary Fault reduction station list.

In one embodiment, the restoration methods for having also correspondingly provided a kind of fail soft base station communication, such as Figure 11 institute Show, includes the following steps:

Step S1010 when itself does not break down, receives the fail soft station list of diffusion, according to the mark of itself Information carries out the update of base station path information in fail soft station list.

Arbitrary Fault weakens in the diffusion of station list, and core net can all receive fail soft station list, core net It does not break down, at this point, believing each base station path in fail soft station list is carried out according to the identification information of itself first The update of breath, to mark core net respectively in each base station path information.

Therefore, it in the diffusion of fail soft station list, carries out the received communications facility of fail soft station list and removes Except base station, core net is further comprised, core net is considered as special base station in fail soft station list.

For example, for including the identification information of Base Station Identification and network address, core network identifier, fail soft base Standing list can following sheet form:

Table 1

Wherein, network address corresponding to base station IP1 and the equal base station base station IP2, and base station IDs 1 and base station IDs 2 are then base Station identifications, core net ID1 are core network identifier.

It should be noted that core net will be special as one kind, the base station of fail soft state is not entered.

Step S1030 returns to the fail soft updated into the base station of fail soft state to core net itself control is lower Station list.

As previously described, core net receives fail soft station list, and is updated to this, but needs especially to say Bright, the S1 link of itself and each base station all interrupts when core net failure, and each base station all enters fail soft state, and core Net will not receive the fail soft base station of diffusion, under the action of fail soft station list, lead between each adjacent base station It crosses X2 link to be communicated, the function of core net script may be not present.

By this process, in LTE cluster communication, an opposite fail soft base station, other base stations and core net to its into Row quick response when entering fail soft state, and then cooperate and realize the fast quick-recovery communicated under fail soft state, Greatly improve robustness.

In another embodiment, as shown in figure 12, this method further include:

Step S1110, core net obtain called subscriber according to the fail soft station list of storage in failed paging Base station and corresponding identification information, base station path information where terminal.

When link is normal between core net for base station, receive the calling that user terminal is initiated, and by with core net it Between link calling is forwarded to core net.

At this point, core net will carry out the paging of called user terminal.

Specifically, signified base station is the base station that itself can be normally carried out communication, can be communicated between core net, And also not there is no failure in core net.Base station the calling initiated of received user terminal refer in the cell of this base station control times The calling that user terminal of anticipating is initiated.

If user terminal initiates the called user terminal of calling not in the cell of this base station control, pass through this base station Link between core net, for example, S1 link, calling is forwarded in core net, to carry out called subscriber by core net The paging of terminal.

Core net is paged by the communication with other base stations, to find called use in the cell that other base stations control Family terminal, if searching out called user terminal not successfully, under the cell for illustrating the base station control for being currently normally carried out communication There is no this called user terminal, need to find this called subscriber in the cell for the base station control for coming into fail soft state Terminal.

Here, since core net stores fail soft station list, and what is recorded in fail soft station list appoints There is corresponding base station user table in meaning base station, therefore the fail soft station list that can be stored by core net itself is realized and entered The lookup of called user terminal in the cell of the base station control of fail soft state.

Specifically, searching in fail soft station list all base station user tables, to obtain using comprising called The base station user table of family terminal, and then the base station user table by obtaining obtains associated identification information, according to this identification information Also corresponding base station path information has been obtained.

Wherein, the base station that obtained associated identification information is identified is the entrance failure where called user terminal The base station of reduction state, called user terminal are present in the cell that this base station is controlled；Obtained base station path information For constructing the link communicated between core net and this base station.

Step S1130 passes through the network address or base station path information and called user terminal place base in identification information It stands communication, the communication between user terminal and called user terminal initiate calling.

As previously described, base station path information can be obtained via identification information, and in one embodiment, identification information Other than including Base Station Identification, the network address where base station is further comprised.Therefore, for being obtained by fail soft station list It has arrived for the core net of identification information and base station path information, it can be to the network address or base station path in identification information Information select a carry out called user terminal communication between the base stations.

On the one hand, according to the network address in identification information, core net directly initiate with the called base station where terminal it Between communication；

On the other hand, core net obtains core net and called user terminal between the base stations by base station path information extraction Base station path, reach the base station passed through required for base station where called user terminal to know from core net, and then pass through S1 Between link and base station X1 link building core net and called user terminal link between the base stations.

In a preferred embodiment, it is preferentially communicated using network address, in the communication carried out by network address When unsuccessful, reuse base station path information and communicated.

By process as described above, when user terminal needs are communicated with the user terminal of other cells, if institute Link is normal between base station and core net, and base station where called user terminal enters fail soft state, then can pass through core The fail soft station list that stores in heart net realizes the communication between user terminal and called user terminal, even and if then wide Even if can also safeguard that all users are whole in broadband cluster system with there is the base station for entering fail soft state in group system The communication at end, so greatly improve communicated in broadband cluster system build strong letter.

In one embodiment, the detailed process of step 1030 includes: according to the mark letter in fail soft station list It ceases to corresponding base station and returns to the fail soft station list that core net itself updates.

As previously described, the diffuseness termination that fail soft station list is carried out is in core net, and core net is considered as Therefore particular base station receives the core net of fail soft station list in the update for completing base station path information, and by core After network mark knowledge is added to fail soft station list as new identification information, recorded into fail soft station list This fail soft station list is returned into each base station of fail soft state, this fail soft list is stored in into event In each base station for hindering reduction state.

By step as described above, so that the base station of entered fail soft state can obtain in broadband cluster system To the fail soft station list finally safeguarded, ensure that can be by fail soft base into the base station of fail soft state List of standing restores communication, and then the S1 link failure not occurred currently by it is influenced.

In one embodiment, received fail soft station list at least two, this method is as shown in figure 13, also wraps It includes:

Step S1210, core net are extracted to obtain like-identified from received at least two fail softs station list respectively The corresponding at least two base station paths information of information.

For core net, since it is communicated between multiple base stations by S1 link, can receive Multiple base stations pass through at least two fail soft station lists that S1 link is sent to, and need at least two event received to institute Barrier reduction station list is integrated, to obtain final fail soft station list.

Since the path of diffusion is different, at least two fail soft station lists, same identification information is corresponding at least Two base station path information are also different, need to accept or reject base station path information, to retain the smallest base station road of hop count Diameter information.

Step S1230 retains the smallest base station path information of hop count at least two base station path information of extraction, loses Other routing informations are abandoned, to merge received at least two fail softs station list.

Target BS is reached by any base station, or the number of base stations passed through required for core net is reached i.e. as any base station For hop count.In at least two base station paths information extracted for same identification information, only retain the smallest base station road of hop count Diameter information retains base station path information corresponding to most short base station path, to realize received at least two fail softs base The screening for the base station path information in list of standing.

In completing at least two fail soft station lists after the screening of base station path information, merge i.e. Can, to obtain final fail soft station list, thus in obtained fail soft station list, identification information is corresponding One base station path information, and most short base station path in this base station path message identification broadband cluster system.

It should be understood that in entire broadband cluster system, all constructed corresponding to it into the base station of fail soft state Fail soft station list, and for by diffusion reach this base station fail soft station list update base station path letter Cease and add the identification information of itself.

The terminal node that core net is spread as fail soft station list will be necessary to handle all fail soft bases It stands list, to obtain finally for its own and entering each base station of fail soft state and using, to improve fail soft base It stands the validity of list.

Method as described above is illustrated below with reference to specific scene.In one embodiment, it is with core net failure Example is illustrated.

As shown in figure 14, in broadband cluster system, when core net failure, S1 link is abnormal between each base station and core net, Therefore each base station all enters fail soft state.

Into that between each base station of fail soft state and can not know mutual state and network address, therefore, enter It is merely able to enter event by the building of fail soft station list and diffusion process notice between each base station of fail soft state Hinder the network address or base station path of other base stations oneself of reduction state, and the fail soft base station being sent to by core net List obtains the network address communicated with the other base stations or core net for entering fail soft state or base station path.

It is corresponding, into other base stations of fail soft state obtain also can be weak by the failure received Change station list and restore communication, so that these enter between the base station of fail soft state, and can between core net Restore communication.

On this basis, the communication recovery between the base station of fail soft state is entered by these, so that user terminal Even if place base station enters fail soft state between, can also guarantee maximum communication success rate and communication range.

In another example as shown in figure 15, the S1 link fails between base station 1 and core net, and base station 2 and core S1 link fails between net, but core net is normal, the S1 link between base station 3 and core net is normal.

In this scenario, base station 1 and base station 2 enter fail soft state, and base station 3 and core net operate normally.

At this point, by the building and diffusion of foregoing fail soft station list, into the base of fail soft state It stands through other base station contacts of normal operation to core net, for example, being arranged for base station 1 according to fail soft base station Table would know that it can relate to the base station path of core net, the i.e. base station 1-> of the base station base station 2-> 3-> core net, wherein base station Between link realize that the link between base station and core net is realized by S1 link by X2 link.

Correspondingly, fail soft station list is constructed by the base station for entering fail soft state, and spread to each base station.? In this diffusion, each base station can be all updated the base station path information in fail soft station list, and itself be in event When hindering reduction state, identification information is added to fail soft station list, and then complete the update of fail soft station list, and Continue the diffusion of fail soft station list.

The base station for itself being in fail soft state will store this fail soft station list, to guarantee that it is receiving core It before the final fail soft station list that heart net is sent to, can also restore to communicate, guarantee communication success rate as much as possible and lead to Believe range.

Certainly, in the diffusion of fail soft station list, the base station of fail soft state is not in only to fail soft base List of standing is updated, and does not need to store fail soft station list.

For another example will be briefly described in the specific implementation level of technology with scene shown in Figure 16.Wherein, ENB1 and eNB2 has respectively corresponded two base stations, and MME is then corresponding core network element.

ENB1 failure causes S1 link down between eNB1 and MME, at this point, eNB1 can only be using it between eNB2 What X2 link transmitted S1 link again establishes message, by the way that eNB2 is newly-built and the Proxy S1 link of MME, thus realize eNB1 and The fast quick-recovery communicated between MME.

In the process, MME does not need perception eNB1 failure, will not impact to the link of other base stations, fastly Speed restores influence caused by failure.

Wherein, program process is as shown in figure 17 when related, i.e. program process when in Figure 17 described in step 1 to step 6. Specifically, after eNB1 discovery S1 link down, the adjacent base station of one normal operation of selection first in existing X2 link, such as eNB2。

ENB1 sends X2AP MESSAGE TRANSFER message, which contains S1SETUP REQ message.

After eNB2 receives the X2 transparent transmission message of S1SETUP REQ, new connecting with the SCTP of MME is initiated first and is built It is vertical.

After the completion of SCTP connection is established, eNB2 replaces eNB1 transparent transmission S1SETUP REQ.

MME replys S1SETUP RSP to eNB2, and the S1 link establishment of acting on behalf of of eNB succeeds at this time.

ENB2 sends X2AP MSG TRANSFER message to eNB1, which is used for the S1SETUP that transparent transmission MME is sent RSP。

Under the above process, eNB1 passes through the X2 proxy message of eNB2, completes S1 link after receiving S1SETUP RSP Recovery, and then restore base station service.
