S101: meet X2 interface in the number judgement being attached according to opposite end base station by core net and this base station and establish When condition, detection is currently with the presence or absence of idle SCTP resource；

In the present embodiment, for this base station and opposite end base station for needing to establish X2 connection, X2 is established at them and is connected It is unable to direct communication before connecing, is needed through core net, for example, see shown in Fig. 2.And the connection of base station and core net is to pass through What S1 interface was realized, therefore, in the present embodiment, the number that opposite end base station is attached by core net with this base station can lead to The switching times of S1 interface are crossed to be counted, the switching times of S1 interface are more, that is, show that the S1 interface is corresponding to end group The number being attached by core net and this base station of standing is more.Therefore, whether a kind of feasible X2 interface set up the condition meets Determination method be:

Determine whether the switching times of S1 interface reach default S1 interface switching times threshold value；If so, determining that meeting X2 connects Mouth set up the condition；Otherwise, continue to determine whether the switching times of S1 interface reach default S1 interface switching times threshold value.

Wherein, presetting S1 interface switching times threshold value can be set according to practical engineering experience by engineer.

In the present embodiment, SCTP resource can be occupied by already present X2 interface, can also be by the other systems of base station Occupied by configuration.If all SCTP resources are occupied in base station, that is, show to provide in base station without available idle SCTP Source.

In the present embodiment, pass through core net and this base for determining whether to meet the opposite end base station of X2 interface set up the condition The number that station is attached can be the opposite end base station in the certain time period of setting and is attached by core net and this base station Number.For example, the connection number from current time in its 24 hour previous.

S102: when there is no idle SCTP resource, detect this base station management in idle time resource whether meet it is default SCTP resource set up the condition；

In the present embodiment, process resource can be the processor resource of base station and the memory source of base station.Therefore, it detects Whether the management in idle time resource of this base station, which meets default SCTP resource set up the condition, specifically may is that

Whether the processor utilization for detecting this base station is less than default first processor utilization threshold, and detects this base station Memory usage whether be less than default first memory usage threshold value；

If the processor utilization of this base station is less than default first processor utilization threshold and the memory of this base station utilizes Rate is less than default first memory usage threshold value, determines that the management in idle time resource of this base station meets default SCTP resource and establishes item Part.

Wherein, it presets first processor utilization threshold and the maximum value of the first memory usage threshold value should be residue Idle processor utilization rate and remaining free memory utilization rate can at least establish a value when SCTP resource.At default first Reason device utilization threshold and the first memory usage threshold value can be set according to practical engineering experience by engineer.

S103: when meeting default SCTP resource set up the condition, it is based on management in idle time asset creation SCTP resource；

Specifically, SCTP resource can be created by the processor of base station.

S104: the SCTP resource based on creation establishes the X2 interface for connecting with opposite end base station communication.

In the present embodiment, after establishing X2 interface, the communication connection of opposite end base station and this base station may refer to Fig. 3 institute Show.

When in the present embodiment, for there is idle SCTP resource, idle SCTP resource can be directly based upon and established The X2 interface being connect with opposite end base station communication.It should be understood that in practical engineering applications, often for according to pre- in base station The X2 interface that the SCTP resource being first equipped with is established can be shown in configuration interface, so as to be controlled automatically by artificial or system The modes such as system are managed these X2 interface, and the X2 interface for being established based on the SCTP resource created later, then will not It is shown in configuration interface, can only be automatically controlled and be managed by system.It, will be this kind of in this implementation for convenient for stating later Extension X2 interface is labeled as based on the X2 interface that the SCTP resource created later is established.Namely step S104 is built in the present embodiment Vertical X2 interface is extension X2 interface.

It is to be further understood that can exist preparatory for the X2 interface established based on the SCTP resource being previously provided with The fixation X2 interface for being connect with fixed opposite end base station communication established in this base station, in practical engineering applications, for Fixed X2 interface can only be the highest part of importance in the X2 interface of base station by being manually managed.And for based on pre- Part in the X2 interface that the SCTP resource being first equipped with is established in addition to fixed X2 interface can pass through simultaneously artificial or system certainly The modes such as dynamic control are managed, to be established this kind of based on the SCTP resource created later in this implementation convenient for stating later X2 interface be labeled as formal X2 interface.

It should be understood that in practical engineering applications, can also configure extension X2 interface with according to being set in advance in base station The X2 interface that some SCTP resources are established is the same to be shown in configuration interface.It should be understood that due to extending X2 interface Foundation be by occupy base station management in idle time resource establishes, therefore will lead to base station spare processing resources amount reduction, It is insufficient to may cause base station Ability of emergency management in certain extreme cases, therefore in practical engineering applications, engineer Dilatation processing can be carried out to base station establishing in a period of time after having extension X2 interface, can will extend X2 interface at this time It is changed to formal X2 interface.

It should be understood that formal for being directly based upon connecting with opposite end base station communication for idle SCTP resource foundation For X2 interface, establishment process is as follows:

This base station sends base station communication transmission request to core net with request transmission configuration, and core net constructs MME (Mobility Management Entity, mobile management module) communications are requested to opposite end base station requests transmission configuration, Base station communication transfer request message is replied to core net in opposite end base station, and the transmission address of opposite end base station, core are carried in the message Heart net responds the MME communications message of the transmission configuration for carrying opposite end base station and transmission address to this base station.It this base station will The transmission configuration of opposite end base station and the transmission configuration of our station of acquisition are reported to background management system and (such as are reported to OMC (Operation and Maintenance Center, operation and maintenance center)), background management system adds two after receiving message Then X2 configuration between standing synchronizes configuration data to this base station；This base station is configured further according to synchronous X2, is initiated X2 and is established stream Journey, it is established that formal X2.

It is to be further understood that can be established using following establishment process for the extension X2 interface of foundation:

Base station sends base station communication transmission request to core net with request transmission configuration, and core net constructs MME communication Transmission request is to opposite end base station requests transmission configuration, and opposite end base station replys base station communication to core net and transmits message, in the message The transmission address of opposite end base station is carried, core net responds the transmission configuration for carrying opposite end base station and transmission address to this base station MME communications message.Transmission configuration and transmission address of the base station according to the opposite end base station of acquisition, are based on management in idle time resource Creation SCTP resource is to establish extension X2 interface.

It should be understood that in the present embodiment, for X2 interface can be being established convenient for differentiating and managing each X2 interface When, corresponding identification information is configured, such as correspondence can be configured for the extension X2 interface of foundation and be identified as extension.

In the present embodiment, if detect that the management in idle time resource of this base station is unsatisfactory for SCTP resource set up the condition, this When a kind of specific processing mode be:

Judge whether the processor utilization of this base station is less than default second processor utilization threshold, and judges this base station Memory usage whether be less than default second memory usage threshold value；

If the processor utilization of this base station is more than or equal to default first memory usage threshold value and is less than at default second The memory usage for managing device utilization threshold or this base station is more than or equal to default first memory usage threshold value and is less than default the Two memory usage threshold values, then the switch instances based on existing each X2 interface delete an existing X2 interface, and establish use In the X2 interface being connect with opposite end base station communication.

Wherein, it presets second processor utilization threshold and is greater than default first memory usage threshold value, preset the second memory Utilization threshold is greater than default first memory usage threshold value.Default second processor utilization threshold and default second memory benefit Spare processor utilization that base station should at least retain and spare memory usage are should be with the maximum value of rate threshold value Value.Default second processor utilization threshold and the second memory usage threshold value can be according to practical engineering experiences by engineer Setting.

In the present embodiment, the switch instances based on existing each X2 interface delete a kind of tool of an existing X2 interface The feasible pattern of body is: obtaining the switching of each X2 interface for several times, and deletes switching the smallest X2 interface for several times.

It should be understood that in the present embodiment, after the switching for several times for obtaining each X2 interface, each X2 interface can be pressed It is ranked up for several times according to switching, and the smallest X2 interface is deleted for several times for the last switching that will sort.

It should be understood that the X2 that the opposite end base station importance to avoid newly-built X2 interface from being connected is not so good as to delete connects The opposite end base station that mouth is connected, can be by the switching time for the corresponding S1 interface in opposite end base station for needing newly-built X2 interface to be connected Several switchings with each X2 interface are compared together for several times, the corresponding S1 in opposite end base station that if desired newly-built X2 interface is connected The switching times of interface are also lower for several times than the minimum switching of each X2 interface, then without above-mentioned delete operation.

It is worth noting that, in practical engineering applications, due to there is fixed X2 interface, fixed X2 interface can only pass through people Work is managed, therefore when obtaining the switching of each X2 interface for several times, can only obtain other X2 in addition to fixed X2 interface The switching of interface for several times, and deletes in other X2 interface in addition to fixed X2 interface and switches the smallest X2 interface for several times.

In the present embodiment, the switching times of each X2 interface of acquisition can be each X2 in the certain time period of setting and connect The switching times of mouth.For example, from current time its a few days ago in each X2 interface switching times.

If all adjacent area opposite ends base station of local terminal base station is higher load condition, i.e., can not immigration load when, this end group It stands and searches whether the adjacent area opposite end base station without X2 connection across base station by core net, if any, base station is to core net The transmission configuration of the eNB CONFIGRATION TRANSFER request opposite end base station is sent, core net constructs MME CONFIGRATION TRANSFER is replied to core net to the opposite end base station requests transmission configuration, the opposite end base station and is carried opposite end The eNB CONFIGRATION TRANSFER message of the transmission address and transmission configuration of base station, core net are returned to local terminal base station again The MME CONFIGRATION TRANSFER message of the transmission address and transmission configuration of opposite end base station should be carried；Local terminal base station root Transmission address and transmission configuration according to the opposite end base station of acquisition, establish interim X2 interface, to establish with the opposite end base station interim X2 connection, to request share loads.

Second, when the mobility index of local terminal base station reduces, local terminal base station passes through core net in base station deployment rarefaction The transmission configuration for obtaining adjacent opposite end base station establishes interim X2 interface, and the transmission configuration of local terminal base station is sent to this to end group It stands, to establish interim X2 connection.When occur re-established across station when, local terminal base station by with occur RLF (Radio Link Failure, Radio Link Failure) the interim X2 connection established of opposite end base station, by RLF INDICATION by RLF information band To the opposite end base station that RLF occurs, so that it carries out MRO, (Mobility robust optimization, mobile robustness are excellent Change) judgement of fault type；When the opposite end base station that RLF occurs is not the source base station of switching, local terminal base station can also be by facing When X2 connection, HANDOVER REPORT message is sent to handover source base station, be used as MRO fault type judge, it might even be possible to touch Send out MRO.

Third, the X2 between the base station of energy-saving cell and the base station of basic coverage cell is connected in base station deployment rarefaction It may accidentally be deleted.At this point, the base station of energy-saving cell checks whether that there are X2 connections between the base station of basic coverage cell, if It is not present, then the base station of serving cell is established interim X2 interface and connected with the interim X2 established between the base station of basic coverage cell It connects.

In addition, the base station of serving cell can be connected by interim X2 in the case of cell carrier is energy saving between station RESOURCE STATUS REQUEST message is sent to the request that neighbor base station is used for load, neighbor base station can be responded RESOURCE STATUS RESPONSE, and load is used for more in the subsequent RESOURCE STATUS UPDATE that periodically replys Newly.The base station of serving cell is judged according to the load of itself and the load of neighbor base station, and carrier wave is triggered when condition meets Energy conservation.

Fourth, can establish between local terminal base station and adjacent area opposite end base station when adjacent area logical root sequence conflicts between there is station Interim X2 connection, at this time opposite end base station can be connected by the interim X2 to local terminal base station send ENB CONFIGURATION UPDATE message, thus by can by the PRACH of opposite end base station (Physical Random Access Channel, physics with Machine accesses channel) information is sent to local terminal base station, and local terminal base station obtains the logical root sequence relevant field of the PRACH information, from And logical root sequence conflict is judged whether there is, if there is the conflict of logical root sequence then triggers logical root sequence optimisation, conflict is solved Certainly.

It should be understood that each step for establishing management method of X2 interface provided in the present embodiment can also lead to The X2 interface crossed on 52 run memory 51 of processor of base station as shown in Figure 5 establishes management program to realize.

X2 interface provided in this embodiment establishes management method, is determined by the detection to base station management in idle time resource, SCTP resource can be created when not idle SCTP resource and process resource are not fully utilized, so that guaranteeing can be with The X2 interface connecting with opposite end base station communication is established, ensure that the normal of base station functions, while also alleviating to a certain extent Because SCTP resource scarcity causes X2 interface that can not create the problem of bring base station system expands bottleneck.Meanwhile passing through interim X2 The setting of interface so as to base station resource compared with scheduling it is more flexible, improve the utilization rate to base station resource.Meanwhile passing through The information exchange that interim X2 connection carries out, base station system can trigger corresponding function according to configuration, have to base station system certain Optimization function improves the forward gain of base station system.

Embodiment three:

It is connect to guarantee that this base station can establish X2 with opposite end base station, to guarantee the normal of base station functions, in the present embodiment Provide a kind of X2 interface establishes managing device, and referring to Figure 14, Figure 14 is a kind of foundation of X2 interface provided in this embodiment The structural schematic diagram of managing device, comprising:

Determination module 141, for base station where establishing managing device by core net and this X2 interface according to opposite end base station The number being attached determines whether to meet X2 interface set up the condition；If satisfied, being also used to detect currently with the presence or absence of the free time SCTP resource；

Determination module 141 is also used to detecting there is currently no when idle flow control transfer resource, continue to test originally Whether the management in idle time resource of base station meets default SCTP resource set up the condition where X2 interface establishes managing device；

X2 interface establishes module 142, for determining that it is default that the management in idle time resource of this base station meets in determination module 141 When SCTP resource set up the condition, it is based on management in idle time asset creation SCTP resource, and the foundation of the SCTP resource based on creation is used for The X2 interface being connect with opposite end base station communication.

In the present embodiment, for this base station and opposite end base station for needing to establish X2 connection, X2 is established at them and is connected It is unable to direct communication before connecing, needs to pass through core net.And the connection of base station and core net is realized by S1 interface, because This, in the present embodiment, opposite end base station can be by the switching of S1 interface by the number that core net and this base station are attached Number is counted, and the switching times of S1 interface are more, that is, show the S1 interface corresponding opposite end base station by core net with The number that this base station is attached is more.Therefore, one kind that determination module 141 determines whether X2 interface set up the condition meets is feasible Method is:

In the present embodiment, SCTP resource can be occupied by already present X2 interface, can also be by the other systems of base station Occupied by configuration.If it is determined that module 141 determines that all SCTP resources are occupied in base station, that is, show in base station without for making Idle SCTP resource.

In the present embodiment, the opposite end base station for determining whether to meet X2 interface set up the condition for determination module 141 passes through The number that core net and this base station are attached can be the opposite end base station in the certain time period of setting and pass through core net and this The number that base station is attached.

In the present embodiment, process resource can be the processor resource of base station and the memory source of base station.Therefore, determine Whether the management in idle time resource that module 141 detects this base station, which meets default SCTP resource set up the condition, specifically may is that

It should be understood that the maximum value of default first processor utilization threshold and the first memory usage threshold value is answered Value when can at least establish a SCTP resource with remaining free memory utilization rate for remaining idle processor utilization rate.In advance If first processor utilization threshold and the first memory usage threshold value can be set according to practical engineering experience by engineer.

In the present embodiment, if it is determined that X2 interface establishes module 142 when module 141 determines to have idle SCTP resource Idle SCTP resource can be directly based upon and establish the X2 interface connecting with opposite end base station communication.It should be understood that in reality In engineer application, often for the X2 interface directly established according to the SCTP resource that is previously provided in base station can configuration interface into Row display, so as to be managed by modes such as artificial or system automatic controls to these X2 interface, and for being based on X2 Interface establishes the X2 interface that the SCTP resource created after module is established, then will not be shown, can only be passed through in configuration interface System automatic control is managed.To be established this kind of based on the SCTP resource created later in this implementation convenient for stating later X2 interface labeled as extension X2 interface.Namely the X2 interface of step S104 foundation in the present embodiment is extension X2 interface.

It should be understood that in practical engineering applications, can also configure extension X2 interface with according to being set in advance in base station The X2 interface that some SCTP resources are established is the same to be shown in configuration interface.It should be understood that since X2 interface is established The foundation of 142 pairs of module extension X2 interface is to be established by occupying the management in idle time resource of base station, therefore will lead to base station Spare processing resources amount reduces, so that it is insufficient to may cause base station Ability of emergency management in certain extreme cases, therefore in reality In the engineer application of border, engineer can carry out dilatation processing to base station establishing in a period of time after having extension X2 interface, Extension X2 interface can be changed to formal X2 interface at this time.

It should be understood that X2 interface establish that module 142 is directly based upon that idle SCTP resource establishes with opposite end base station The establishment process of the formal X2 interface of communication connection may is that

Base station communication transmission request first is sent with request transmission configuration to core net, and core net constructs MME (Mobility Management Entity, mobile management module) communications are requested to opposite end base station requests transmission configuration, Base station communication transfer request message is replied to core net in opposite end base station, and the transmission address of opposite end base station, core are carried in the message Heart net responds the MME communications message of the transmission configuration for carrying opposite end base station and transmission address to this base station.This base station X2 Interface establishes the transmission configuration of opposite end base station that module 142 will acquire and the transmission configuration of our station is reported to background management system (such as being reported to OMC (Operation and Maintenance Center, operation and maintenance center)), background management system are received The X2 configuration between two stations is added after to message, then synchronizes configuration data to this base station；The X2 interface of this base station establishes module 142 It is configured further according to synchronous X2, initiates X2 Establishing process, it is established that formal X2.

It is to be further understood that the establishment process that X2 interface establishes the foundation extension X2 interface of module 142 may is that

X2 interface establishes module 142 and sends base station communication transmission request to core net with request transmission configuration, core Net construction MME communications are requested to opposite end base station requests transmission configuration, and base station communication transmission is replied to core net in opposite end base station Message, the transmission address of opposite end base station is carried in the message, and core net responds the transmission for carrying opposite end base station to this base station The MME communications message of configuration and transmission address.X2 interface establishes module 142 according to the transmission configuration of the opposite end base station of acquisition With transmission address, extension X2 interface is established based on management in idle time asset creation SCTP resource.

It should be understood that in the present embodiment, for convenient for differentiating and managing each X2 interface, X2 interface establishes module 142 Corresponding identification information can be configured, such as corresponding mark can be configured for the extension X2 interface of foundation when establishing X2 interface Know for extension.

In the present embodiment, if it is determined that module 141 detects that the management in idle time resource of this base station is unsatisfactory for SCTP resource and builds When vertical condition, specific processing mode a kind of at this time is:

Determination module 141 continues to judge whether the processor utilization of this base station is less than default second processor utilization rate threshold Value, and judge whether the memory usage of this base station is less than default second memory usage threshold value；

If the processor utilization of this base station is more than or equal to default first memory usage threshold value and is less than at default second The memory usage for managing device utilization threshold or this base station is more than or equal to default first memory usage threshold value and is less than default the Two memory usage threshold values, then it is existing to establish switch instances deletion one of the module 142 based on existing each X2 interface for X2 interface X2 interface, and establish X2 interface for connecting with opposite end base station communication.

Wherein, the maximum value for presetting second processor utilization threshold and default second memory usage threshold value should be base It stands the value of the spare processor utilization and spare memory usage that should at least retain.Default second processor utilization rate threshold Value and the second memory usage threshold value can be set according to practical engineering experience by engineer.

In the present embodiment, X2 interface establishes module 142 and has deleted one based on the switch instances of existing each X2 interface A kind of specific feasible pattern of X2 interface be:

The switching of each X2 interface is obtained for several times by determination module 141, X2 interface establishes module 142, and to delete switching minimum for several times X2 interface.

It, can be with after determination module 141 obtains the switching for several times of each X2 interface it should be understood that in the present embodiment Each X2 interface is ranked up for several times according to switching, it is the smallest for several times to establish the last switching that will sort of module 142 by X2 interface X2 interface is deleted.

It should be understood that the X2 that the opposite end base station importance to avoid newly-built X2 interface from being connected is not so good as to delete connects The opposite end base station that mouth is connected, the corresponding S1 in opposite end base station that determination module 141 can will need newly-built X2 interface to be connected The switching times of interface and the switching of each X2 interface are compared together for several times, the opposite end that if desired newly-built X2 interface is connected The switching times of the corresponding S1 interface in base station are also lower for several times than the minimum switching of each X2 interface, then X2 interface establishes module 142 not Carry out delete operation.

It is worth noting that, in practical engineering applications, due to there is fixed X2 interface, fixed X2 interface can only pass through people Work is managed, therefore when obtaining the switching of each X2 interface for several times, determination module 141 can only obtain except fixed X2 interface with For several times, X2 interface establishes module 142 and deletes other X2 in addition to fixed X2 interface at this time for the switching of other outer X2 interface Switch the smallest X2 interface for several times in interface.

In the present embodiment, the switching times for each X2 interface that determination module 141 obtains can be setting sometime The switching times of each X2 interface in section.

It is worth noting that, in the present embodiment, X2 interface, which establishes managing device, can also establish interim X2 interface, with Base station is functional to be established when needing for base station and connect with the interim X2 of opposite end base station, and the necessary message for certain functions is transmitted.

It is built specifically, determination module 141 is also used to determine whether to meet according to the base station information of this base station interim X2 interface Vertical condition；

X2 interface establishes module and is also used to establish and use when determination module 141 determines to meet interim X2 interface set up the condition In the interim X2 interface being connect with opposite end base station provisional communication.

It should be understood that in the present embodiment, X2 interface establishes managing device and establishes a kind of feasible of interim X2 interface Mode is:

When self-organizing network in this base station of the judgement of determination module 141 is opened and mobility index declines or this base station When self-organizing network is opened and is in higher load condition, continue to determine this base station with the presence or absence of idle SCTP resource；

If base station has idle SCTP resource, X2 interface is established module 142 and is established by existing free time SCTP resource Interim X2 interface, its process for establishing interim X2 interface is consistent with the process for establishing formal X2 interface at this time.

If there is no idle SCTP resource, determination modules 141 to continue to judge whether management in idle time resource meets for base station Default flow control transfer resource set up the condition.If satisfied, then X2 interface establishes the creation SCTP resource of module 142, and based on creation SCTP resource establish interim X2 interface.The process one of its process for establishing interim X2 interface and foundation extension X2 interface at this time It causes.

It should be understood that in the present embodiment, X2 interface establish managing device establish the another kind of interim X2 interface can Line mode is:

When the self-organizing network of 141 this base station of determination module is opened and mobility index declines or this base station from group Knitmesh network open and be in higher load condition when, determination module 141 directly detect this base station management in idle time resource whether meet it is pre- If flow control transfer resource set up the condition, X2 interface establishes module 142 and creates SCTP resource if meeting, and based on creation SCTP resource establishes interim X2 interface.

Specifically, this base station self-organizing network open and mobility index decline when or this base station self-organization network When network is opened and is in higher load condition, it is default whether the processor utilization that determination module 141 directly detects this base station is less than First processor utilization threshold, and whether the memory usage for detecting this base station is less than default first memory usage threshold value.

If the processor utilization of this base station is less than default first processor utilization threshold and the memory of this base station utilizes Rate is less than the default first memory usage threshold value, and judgement meets interim X2 interface set up the condition, and X2 interface establishes module 142 Create SCTP resource by the processor of this base station, and the SCTP resource based on creation establish for opposite end base station provisional communication The interim X2 interface of connection.

It should be understood that X2 interface is established module 142 and can established temporarily for convenient for the management to interim X2 interface When X2 interface, it is interim to configure being identified as interim X2 interface.

It is worth noting that, in practical engineering applications, to guarantee that establishing module 142 in X2 interface needs to establish formal X2 Interface has enough free time SCTP resources, often adopts so that this base station can establish formal X2 with certain opposite end base station when connecting It is that above-mentioned second interim X2 interface establishes mode.

In the present embodiment, aforementioned to be based on existing each X2 for the case where can establish interim X2 interface The switch instances of interface delete an existing X2 interface, and when X2 interface of the foundation for connecting with opposite end base station communication, sentence Cover half block 141, which can be obtained only, to be switched the smallest X2 for several times in each X2 interface in addition to fixed X2 interface and interim X2 interface and connects Mouthful, X2 interface establishes module 142 and deletes switching the smallest X2 interface for several times at this time.Formal X2 interface and extension can only be obtained Switch the smallest X2 interface for several times in X2 interface and deletes.

Referring to Figure 15, in the present embodiment, default second processor is more than or equal to for the processor utilization of this base station The case where utilization threshold or the memory usage of this base station are more than or equal to default second memory usage threshold value, show at this time Management in idle time resource needs to discharge the occupied processing money in part to be lower than necessary spare processing resources warning value in this base station Source.At this point, determination module 141 can detecte base station with the presence or absence of interim X2 interface；If it exists, then resource release module 143 is pressed According to preset interim X2 interface deletion rule, at least one interim X2 interface is deleted, to discharge base station process resource.

X2 interface provided in this embodiment establishes managing device, is passing through core according to opposite end base station by determination module When the number judgement that net and this base station are attached meets X2 interface set up the condition, if detecting, there is currently no idle flow controls Transfer resource (SCTP resource) processed, then whether the management in idle time resource for continuing to test this base station, which meets default SCTP resource, is established item Part, and when meeting, module is established by X2 interface and is based on management in idle time asset creation SCTP resource, then the money of the SCTP based on creation The X2 interface for connecting with opposite end base station communication is established in source.In this way, determined by the detection to base station management in idle time resource, it can To create SCTP resource when not idle SCTP resource and process resource are not fully utilized, to guarantee to build The vertical X2 interface connecting with opposite end base station communication, ensure that the normal of base station functions, at the same also alleviate to a certain extent because SCTP resource scarcity causes X2 interface that can not create the problem of bring base station system expands bottleneck, furthermore also improves base station The utilization rate for managing resource, reduces the wasting of resources.
