Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing pair
Technical solution of the present invention is described in further detail.It should be noted that in the case of not conflicting, this
Feature in the embodiment of application and embodiment can arbitrarily be mutually combined.
Embodiment 1
The present embodiment provides a kind of method of X2 connection establishment, as it is shown on figure 3, mainly include grasping as follows
Make:
Step 301, in transport layer address acquisition procedure, target BS perception its support with source base station
During X2 gateway GW difference, target BS and source base station consult to determine the X2GW of common support；
Step 302, sets up X2 by the common X2GW supported between target BS with source base station and is connected.
Wherein, its X2GW supported with source base station of target BS (such as, eNB or HeNB) perception
Time different, can increase or update X2GW so that the X2GW after increasing or updating and source base
Stand support consistent.Such as, when target BS is eNB, target BS increases X2GW so that increase
X2GW consistent with what source base station was supported, and the X2GW increased is fed back to source base station.Mesh
When mark base station is HeNB, target BS updates X2GW so that the X2GW of renewal props up with source base station
That holds is consistent, and the X2GW of renewal is fed back to source base station.
It addition, in transport layer address acquisition procedure, or target BS judges unnecessary renewal
During X2GW, the X2GW (or X2GW list) that oneself is supported can be fed back to source base station,
By source base station judge whether oneself perform increase or update X2GW, so it is also ensured that source base station and
The X2GW that target BS is supported is consistent.Wherein, when source base station is eNB, source base station is from target BS
The X2GW supported selects increase X2GW so that the X2GW increased and the one of target BS support
Cause.If source base station is HeNB, source base station selects to update from the X2GW that target BS is supported
X2GW so that the X2GW of renewal is consistent with what target BS was supported.
It is noted that the register update process of HeNB needs on the basis of existing LTE R12 agreement
Amendment, current LTE R12 agreement is only supported registration, is not supported to go registration, so needing amendment at present
Register flow path, increases and removes registering functional.I.e. source base station selects to update from the X2GW that target BS is supported
Before X2GW, first the X2 application protocol AP layer link that there is currently is discharged, and releasing
Cheng Hou, goes registration to current X2GW, after going registration to complete, to the X2GW selecting renewal
Transmission registration message.
Below in conjunction with accompanying drawing and the detailed implementation of concrete application note said method.
Below using eNB as source base station, as a example by HeNB is as target BS, illustrate that eNB consults more
The process of new X2GW, this process is as shown in Figure 4.
ENB is as source base station, and target BS is HeNB, in transport layer address acquisition response message,
HeNB returns its X2GW, this X2GW supported and is not comprised in the X2GW row that eNB supports
In table, now eNB and HeNB does not support identical X2GW, the X2GW that eNB supports from HeNB
Middle one X2GW of interpolation that selects, i.e. performs one and registers this X2GW process, thus the two supports
Identical X2GW, source base station eNB can be initiated indirect X2 smoothly and set up.
Again using eNB as target side base station, as a example by HeNB is as source base station, illustrate that eNB consults to update
The process of X2GW, this process is as shown in Figure 5.
ENB is as target side base station, and source base station is HeNB, in transport layer address acquisition request message,
The X2GW that HeNB supports is not in the X2GW list that eNB supports, eNB selects to add HeNB
The X2GW, i.e. eNB supported performs a process registering this X2GW, and rings in transport layer address
Answer and message is carried this X2GW, after source base station HeNB perception, indirect X2 can be initiated smoothly and set up.
HeNB is as source base station, and when eNB is as target BS, HeNB consults to update X2GW's
Process is as shown in Figure 6:
HeNB is source base station, and eNB is target BS.Carry in transport layer address response message is
The X2GW list that eNB supports, wherein, the X2GW that HeNB does not supports.The most now HeNB
Judge that setting up X2 link with this eNB is worth bigger, the X2GW list that HeNB supports from eNB
One X2GW of middle selection, the i.e. X2GW that HeNB newly supports.
After selection, HeNB to first carry out and old X2GW gone registration process.
Before carrying out registration process, the X2AP layer link existed before to be discharged by HeNB,
I.e. send X2 REMOVAL REQUEST message to all of X2 linking objective, and collect target
After the X2 REMOVAL RSPONSE message returned or waiting timer time-out, it is right that HeNB performs
Old X2GW goes registration process.
LTE R12 agreement only supports (H) eNB registration process to X2GW at present, then we need
X2AP MESSAGE TRANSFER message increases a field be shown to be registration still go registration,
Now HeNB sends to old X2GW and removes registration message.
After going registration, HeNB sends registration message to the above-mentioned new X2GW chosen.
In sum, HeNB achieves the renewal process of X2GW.
Now source base station HeNB and target BS eNB supports identical X2GW, and HeNB can be suitable
Profit is initiated indirect X2 and is set up.
HeNB is as target side base station, and when eNB is as source base station, HeNB consults to update X2GW
Process as shown in Figure 7.
HeNB is target side base station, and eNB is source base station.Transport layer address request is carried
The X2GW, HeNB that in the X2GW list that eNB supports, HeNB does not supports judges and is somebody's turn to do
ENB sets up X2 link and is worth bigger, and HeNB decision-making is supported from eNB for updating X2GW, HeNB
X2GW list in select an X2GW, the i.e. X2GW that HeNB newly supports.
The X2GW renewal process of HeNB is with described in above-mentioned Fig. 6, i.e. HeNB selects new X2GW
Afterwards, HeNB to first carry out and old X2GW gone registration process.
Before carrying out registration process, the X2AP layer link existed before to be discharged by HeNB,
I.e. send X2 REMOVAL REQUEST message to all of X2 linking objective, and collect target
After the X2 REMOVAL RSPONSE message returned or waiting timer time-out, it is right that HeNB performs
Old X2GW goes registration process.
LTE R12 agreement only supports (H) eNB registration process to X2GW at present, then we need
X2AP MESSAGE TRANSFER message increases a field be shown to be registration still go registration,
Now HeNB sends to old X2GW and removes registration message.
After going registration, HeNB sends registration message to the above-mentioned new X2GW chosen.
In sum, HeNB achieves the renewal process of X2GW.
The X2GW that HeNB newly supports, source base station eNB is carried in transport layer address response message
Indirect X2 can be initiated after perception smoothly set up.
HeNB2 is as target side base station, and when HeNB1 is as source base station, HeNB2 consults to update
The process of X2GW is as shown in Figure 8.
HeNB2 is target BS, and HeNB1 is source base station.Transport layer address request is carried
HeNB1 support X2GW be not HeNB2 support X2GW, HeNB2 judge with should
HeNB1 sets up X2 link and is worth bigger, and HeNB2 decision-making is to be updated to the X2GW that HeNB1 supports.
The X2GW renewal process of HeNB2 is with described in above-mentioned Fig. 6, i.e. HeNB2 selects new X2GW
Afterwards, HeNB2 to first carry out and old X2GW gone registration process.
Before carrying out registration process, the X2AP layer link existed before to be discharged by HeNB2,
I.e. send X2 REMOVAL REQUEST message to all of X2 linking objective, and collect target
After the X2 REMOVAL RSPONSE message returned or waiting timer time-out, HeNB2 performs
Old X2GW gone registration process.
LTE R12 agreement only supports (H) eNB registration process to X2GW at present, then we need
X2AP MESSAGE TRANSFER message increases a field be shown to be registration still go registration,
Now HeNB2 sends to old X2GW and removes registration message.
After going registration, HeNB2 sends registration message to the above-mentioned new X2GW chosen.
In sum, HeNB2 achieves the renewal process of X2GW.
The X2GW that HeNB2 newly supports, source base station HeNB1 is carried in transport layer address response message
Indirect X2 can be initiated after perception smoothly set up.
