The invention provides a kind of optimization method of X2 links, the number linked with the X2 of base station chaining can be worked as and reach institute
X2 links when stating the maximum number of the X2 links that base station can be set up to base station are optimized.The method includes：When receiving it
When request is set up in his X2 links, the combination according to one or more linked in duration, information on load, switching demand disconnects existing
X2 links, the number of links of disconnection is not less than the number of the foundation request of the X2 links for receiving.
Wherein, the maximum number that the X2 that the number linked with the X2 of base station chaining reaches the base station and can set up is linked can be worked as
Mesh, the X2 for referring to being established the link with base station at present is linked and is not met X2 and link from the condition deleted, i.e., existing X2 links
It is not belonging to delete the X2 links of X2AP configuration triggerings, is not belonging to delete the X2 links of neighboring BS relationship triggering, is not belonging to the black lists of X2
The X2 links of triggering are changed, is also not belonging to scan the X2 links of invalid X2AP triggerings.
Fig. 1 shows the schematic diagram of LTE network interface, as shown in figure 1, because the X2 for being established the link with base station at present is linked
X2 links are not met from the condition deleted, therefore, when there is new X2 linking requests, only pair established the link with base station
X2 links are optimized, and delete the unnecessary X2 links of respective number, could set up new link, so that it is guaranteed that with base station phase
The X2 link moment of connection is all optimal link, improves resource utilization, improves Consumer's Experience.Below, will be with reference to accompanying drawing pair
The optimization method of X2 links of the invention is described in detail.
Referring to Fig. 2, when the maximum number that the X2 that the number that the X2 with base station chaining is linked reaches the base station and can set up is linked
Mesh and receive other X2 link set up request when, can using manually select or it is adaptively selected by the way of select optimization base
The X2 links stood.If selection manual mode is optimized, can according to link duration, information on load, the one kind in switching demand or
Various combinations disconnects existing X2 links.
Specifically, being disconnected the step of existing X2 is linked according to link duration specifically including：In deleting existing X2 link
X2 most long is linked with the base station chaining time, the newly-built X2 links for needing to set up.Particularly, when the foundation of the X2 links for receiving
When the number of request is more than one, the order successively decreased successively according to link time is deleted existing X2 and is linked, the link number of deletion
Mesh is not less than the number of the foundation request of the X2 links for receiving.For example, in one embodiment of the invention, base station eNB 1 is
Through and M1X2 links are set up in individual base station, have reached the maximum X2 link numbers that this base station can be set up, and now have N again1(M1＞=N1)
Individual base station meets and eNB1 sets up the demand that X2 is linked, then according to the time length established the link with base station to having established the link
M1Individual X2 links are ranked up, according to link time sequentially opened link time from long to short N most long1It is individual to have connected
X2 is linked, for setting up new connection.
Specifically, being disconnected the step of existing X2 is linked according to information on load specifically including：Delete to end load minimum
X2 is linked；Or delete the X2 links of the load difference minimum of opposite end and local terminal.Load herein is X2 interface transport layer IP laminar flows
Amount, for reflecting system MAC layer load condition, represents network load situation and system processing power, load letter to a certain degree
Breath can have user to be transmitted by UE Signalling exchanges when two minizones carry out S1 switchings；Preferably, due to up-downgoing
Data traffic may be asymmetric, therefore X2 interface flow is divided into two indices：X2 interface uplink traffic and X2 interface downlink traffic
(up-downgoing herein is directed to for base station), the load difference of opposite end and local terminal is X2 interface uplink traffic and X2 interface downstream
Difference between amount.System processing power to end load or opposite end and the load difference minimum specification of the local terminal port is weaker.By
In knowing that the load difference of two cells is exactly to understand user potentially to switch demand, in current operation system, high load capacity is small
User can be switched to adjacent underload cell by area.Therefore, it can to delete in existing connection to end load or opposite end and local terminal
The minimum X2 links of load difference setting up new link.Preferably, when the number of the foundation request of the X2 links for receiving is big
When one, existing X2 chains are deleted by the load difference of incremented by successively or opposite end and local terminal to end load order incremented by successively
Connect, the number of links of deletion is not less than the number of the foundation request of the X2 links for receiving.For example, in one of the invention implementation
In example, base station eNB 1 is and M2X2 links are set up in individual base station, have reached the maximum X2 link numbers that this base station can be set up, now
There is N again2(M2＞=N2) individual base station meets and eNB1 sets up the demand of X2 links, then according to end load (or opposite end and local terminal
Load difference) to the M that has established the link2Individual X2 links are ranked up, according to end load (or load difference of opposite end and local terminal)
The sequentially opened N minimum to end load (or load difference of opposite end and local terminal) from low to high2The individual X2 links for having connected, are used for
Set up new connection.
Specifically, being disconnected the step of existing X2 is linked according to switching demand specifically including：Set up when X2 links and ask right
When the switching demand of the X2 links the answered X2 minimum higher than demand in original X2 links is linked, linked with new X2 and replace original X2
The minimum X2 links of demand in link.Specifically, switching demand refers to the switching demand that two minizones are based on X2 interface, according to
The switching times based on S1 interfaces of mesh the first two minizone are obtained, and two minizones are meant that the switching demand based on X2 more
The necessity for setting up X2 interface is strong, therefore optimizes the efficiency that can effectively improve system to X2 links based on demand.It is preferred that
, when the number of the foundation request of the X2 links for receiving is more than one, the corresponding X2 chains of request are set up into X2 links successively
The minimum X2 of demand is linked and is compared during the switching demand for connecing is linked with original X2.For example, in one embodiment of the present of invention
In, base station eNB 1 sets up X2 links with M3 base station, has reached the maximum X2 link numbers that this base station can be set up, now again
There is N3(M3＞=N3) individual base station meets and eNB1 sets up the demand that X2 is linked, then according to switching demand respectively to having set up chain
The M for connecing3Individual X2 links and N to be linked3Individual X2 links are ranked up, afterwards, by N to be linked3Switching in individual X2 links needs
Seek maximum link N3-MAXWith M3Switch the minimum link M of demand in individual X2 links3-MINIt is compared.If N3-MAXIt is less than
M3-MIN, then the minimum N of ascending as desired sequentially opened demand2The individual X2 for having connected is linked for setting up new company
Connect；If N3-MAXMore than M3-MIN, then by N to be linked3Switch demand in individual X2 links and be only second to N3-MAXLink N3-MAX-1With
M3-MINIt is compared, if N3-MAX-1Less than M3-MIN, then the minimum N of ascending as desired sequentially opened demand2- 1
The X2 for having connected is linked for setting up except N3-MAXNew connection in addition, then to N if being less than3-MAX-2Less than M3-MINEnter
Row compares, by that analogy.If N to be linked3Switch the minimum link N of demand in individual X2 links3-MAX-NSwitching demand be more than
M3Switch the minimum link M of demand in individual X2 links3-MIN, then illustrate that the switching demand of existing link is optimal, do not turn off existing
Link.
Referring to Fig. 3, the method to the existing X2 links of disconnection of self adaptation in an alternative embodiment of the invention is carried out
Describe in detail, specifically, comprising the following steps：
When multiple X2 links to be linked are substituted requirement while meeting according to link duration, information on load, switching demand
When, set switching times threshold value and information on load threshold value；If the switching times of X2 links to be linked are less than switching time
Number threshold value, and its information on load is less than information on load threshold value, then disconnect existing X2 links according to link duration；If treated
The switching times of the X2 links of link are more than switching times threshold value, and its information on load is less than information on load threshold value, then root
Existing X2 is disconnected according to information on load to link；If the switching times of X2 links to be linked are more than switching times threshold value, and
Its information on load is more than information on load threshold value, then calculate the threshold parameter of switching times and the thresholding ginseng of information on load respectively
Number, existing X2 links are disconnected according to threshold parameter mode high.Wherein, the switching times for X2 to be replaced being linked are divided by institute
State the threshold parameter that switching times thresholding is worth to the switching times；The information on load that X2 to be replaced is linked is divided by described
Cutting load information limit obtains the threshold parameter of the information on load.
One embodiment that wall scroll X2 after the one of the invention X2 link full configuration based on switching statistics is replaced is entered below
Row is described in detail.Manual configuration X2 corresponding strategies first；The strategy refers to the X2 replacement policies based on switching times, for example, have by oneself
Pattern and controlled mode, with regard to carrying out X2 replacements immediately after switching times meet trigger condition, controlled mode is full to free schema
Also manually to be confirmed whether to be replaced after sufficient condition, different patterns indicates mode of operation different, and without influence, the present invention is right
The scheme that X2 is replaced is in itself.
Afterwards, X2 statistics addition switches are opened, by the policy distribution to system.After the X2 of base station links full configuration, add
Plus neighboring BS relationship.Afterwards, system enters measurement period, and terminal reports switching, system statistics institute in a complete measurement period
There is switching (switching in and out) number of times of adjacent area.After time-out is counted, system subtracts position with the switching times that X2 to be added is linked
In the switching times that the formal X2 of tail of the queue is linked, the as a result switching more than configuration offsets threshold value, then starts and replace flow.It
Afterwards, system reports X2 to link and deletes, and deletes the worst formal X2 links of sequence, and reports X2 to link addition, adds switching times
Preferable X2 links.Afterwards, system reports correspondence X2 links monitoring and KPI to operation maintenance personnel.If strategy is configured to free schema,
Then system directly adds X2 links；If controlled mode, then adding procedure needs operation maintenance personnel to be confirmed, if O＆M people
Member confirms to continue, then system addition X2 links, if it is confirmed that cancelling, then flow terminates.
When there is a plurality of X2 replacements after X2 link full configurations, the link corresponding strategies of manual configuration X2 first, the strategy bag
Include own pattern and controlled mode.Afterwards, X2 link statistics addition switches are opened, by the policy distribution to system.Work as base station
X2 link full configuration after, add neighboring BS relationship.Afterwards, system enters measurement period, terminal in the complete measurement period on
Report switching, switching (switching in and out) number of times of all adjacent areas of system statistics.After time-out is counted, to all adjacent area switching times
It is ranked up from high to low, and filters out base station to be added and to be deleted, system is successively in list to be added and to be deleted
Base station judged, when the switching times of switching times highest base station in list to be added and switching times in list to be deleted
The difference of the last base station switching times of sequence then meets replacement condition more than or equal to switching skew thresholding, and system continues to list
The carrying out of the middle second place judges that, until screening number reaches the maximum operand of system permission, system enters replaces flow, it
Afterwards, system is according to maximum operand, reports X2 to link and deletes, and deletes the X2 links that condition is met in list to be deleted；Report X2
Link addition, addition meets the X2 links of condition.Afterwards, system reports correspondence X2 links monitoring and KPI to operation maintenance personnel.If plan
Free schema is slightly configured to, then system directly adds X2 links；If controlled mode, then adding procedure needs operation maintenance personnel to enter
Row confirms, if operation maintenance personnel confirms to continue, system addition X2 links, and if it is confirmed that cancelling, then flow terminates.
