Description
Technical field
The present invention relates to the communications field, more particularly to a kind of optimization method and device of neighbor cell relation configuration.
Background technology
As shown in fig.1, in Long Term Evolution (Long Term Evolution, LTE), eNB is configuring itself link
During mobility management entity (Mobility Management Entity, MME), S1 link setup processes can be triggered, and in triggering
During inter-MME S1 handoff procedures, it is necessary to network element include：There is S10 between two eNB, two MME, two MME
Orifice, two eNB are connected respectively on two different MME, and the cell under two eNB establishes adjacent cell pass
System.
As shown in fig.2, S1 link establishments are excessively as follows：
Step 200：ENB sends S1 SETUP REQUEST to MME (i.e. S1 sets up request message).
Step 210：MME returns to S1 SETUP RESPONSE (i.e. S1 sets up response message) to eNB, and MME can be in S1
The configuration parameter table for carrying out neighbor cell relation configuration is carried in SETUP RESPONSE, it is specific as shown in table 1, eNB according to
The configuration parameter table of acquisition carries out configuring good parameter as shown in table 2 between adjacent cell configuration, two eNB of wireless side, i.e., adjacent
Cell is successfully established.
When two eNB are connected respectively to two different MME, adjacent cell and neighbor cell relation have been configured in two eNB
And after S10 interfaces between two MME are connected, you can normally trigger inter-MME S1 switchings, you can with by some UE by
The MME that the eNB of its current home is linked switches to the eNB linked under another MME.
But, at present, the problem of currently encountering be, when two eNB are connected on different MME, and between two MME
When being connected in the absence of S10 interfaces, the configuration parameter table that the MME that the eNB of wireless side can also be linked according to itself be issued is normally
Adjacent cell and neighbor cell relation are configured, any exception is not reported, until during test, when the measurement report that terminal is reported illustrates adjacent cell
And neighbor cell relation addition is normal, during triggering inter-MME switchings, eNB sends handover request (Handover to MME
Required), the resource that MME asks adjacent MME to switch over prepares, but because S10 mouthfuls, institute is not present between two MME
Prepare failure to reply resource.
Table 1
(S1 Setup Response parameter lists)
(selecting from 3GPP 36.413)

Embodiment
Improve switching efficiency of the terminal in minizone, it is to avoid in the unnecessary wasting of resources, the embodiment of the present invention, it is small in neighbour
Area and neighbor cell relation network environment configuration phase, will pass through interaction between network element network environment status among each other, and
It is not just to find that the S10 interfaces between two MME are obstructed when the test implementation stage, influence business checking.
Invention is preferred embodiment described in detail below in conjunction with the accompanying drawings.
In the embodiment of the present invention, in the relevant parameter of Inter-MME S10 interface configuring MMEs, on each MME
Its all adjacent MME information is preserved, it is specific as shown in table 3：
Table 3
(Relative MME S10 list)
| MME0S10 interfaces | MME1 | MME2 | MME3 |
| In the presence of | In the presence of | It is not present |
For example, it is assumed that be configured with information as shown in table 3 on MME X, referred to as S10 interface conjunctionns information, according to this letter
Breath, MME X can know that itself there is S10 interfaces between MME 1 is connected, and has S10 interfaces between MME 2 and is connected, and
It is connected between MM3 in the absence of S10 interfaces.
As shown in fig.3, in the embodiment of the present invention, neighbor cell relation configuration flow is as follows：
Step 300：First eNB obtains S10 interfaces when the first MME with own home is established the link from the first MME
Related information, the S10 interface conjunctionns information is used to the presence or absence of S10 interfaces connect between the first MME of sign MME adjacent with each
Connect.
Specially：First eNB sends S1 to the first MME and sets up request, and the S1 that the first eNB receives the first MME returns is set up
Response, and the specific field set up in the S1 in response obtains S10 interface conjunctionn information.
For example：During the MME that the first eNB configurations are linked certainly, S1 link setups process (specific as shown in Figure 2) can be triggered, the
One MME is in S1setup response message by configuration parameter table by S10 interface conjunctionns information (for example, as shown in table 3)
The first eNB is replied to, its first MME for being connected of the first eNB is informed, there is S10 interfaces between which MME and be connected, for example,
It is specific as shown in table 4.First eNB is received after this message, and the specific field in configuration parameter table parses parameter Relative
MME S10 list, and preserved as S10 interface conjunctionns information.

(new addition parameter Relative MME S10 list)
Step 310：First eNB with the 2nd eNB when carrying out adjacent cell configuration, based on the S10 interfaces obtained from the first MME
Related information judges to whether there is S10 interfaces between the 2nd MME of the first MME and the 2nd eNB ownership, if so, then performing step
320；Otherwise, step 330 is performed.
Step 320：First eNB determines to allow UE to trigger inter-MME switching flows between the first MME and the 2nd MME.
Step 330：First eNB determines not allowing UE to trigger inter-MME switching streams between the first MME and the 2nd MME
Journey.
In the present embodiment, after the S1setup response message of the first MME replies is received, the first eNB's is adjacent small
Area's configuration is only needed it is important to note that X2 interface connection refers to here still according to original parameter collocation method (for example, as shown in table 2)
Show, be configured to " presence ", although be configured to exist, but because the first eNB and the 2nd eNB is connected under different MME, and
X2 switchings (can just occur X2 switchings between two eNB being only connected under identical MME) will not be triggered, but can be triggered
Inter-MME switches, the reason for being configured to exist be in order to using X2 link setups process (as shown in Figure 4 specific), it is above-mentioned to complete
Whether S10 interfaces have the inspection of connection between two MME that two eNB are connected.
Specifically, step 310 can use but be not limited to following two implementations：
The first implementation is：First eNB sends X2 to the 2nd eNB and sets up request message (X2Setup Request),
Wherein, the 2nd eNB is eNB adjacent with the first eNB under the 2nd MME, then, and the first eNB receives the X2 foundation that the 2nd eNB is returned
Response message (X2Steup Response), the X2 sets up in response message the S10 interface conjunctionns letter for carrying the 2nd MME transmissions
Breath, and the S10 interface conjunctionns information that the first eNB is sent according to the first MME judges that there is S10 between the 2nd MME and the first MME connects
Mouthful, and when there is S10 interfaces between S10 interface conjunctionns information judgement the first MME and the 2nd MME sent according to the 2nd MME,
Determine there is S10 interfaces between the first MME and the 2nd MME；Otherwise, it determines being connect between the first MME and the 2nd MME in the absence of S10
Mouthful.
Obviously, under the first implementation, between the first MME and the 2nd MME with the presence or absence of S10 interfaces judgement be by
What the first eNB was completed.
Second of implementation be：First eNB sends X2 to the 2nd eNB and sets up request message, and the X2 sets up request message
In carry the first MME transmission S10 interface conjunctionn information, wherein, the 2nd eNB be the 2nd MME under it is adjacent with the first eNB
ENB, then, the first eNB receive the X2 that the 2nd eNB returns and set up response message, and set up response message according to X2 and know second
S10 related informations that eNB is sent according to the first MME judge there is S10 interfaces between the 2nd MME and the first MME, and according to the
When the S10 related informations that two MME are sent judge to there is S10 interfaces between the first MME and the 2nd MME, the first MME and second is determined
There is S10 interfaces between MME；Otherwise, it determines S10 interfaces are not present between the first MME and the 2nd MME.
Obviously, under second of implementation, between the first MME and the 2nd MME with the presence or absence of S10 interfaces judgement be by
What the 2nd eNB was completed.
Specific application scenarios are provided by taking the first implementation as an example below.
For example：In adjacent cell configuration phase, the first eNB knows that itself X2 interface between the 2nd eNB is connected instruction and matched somebody with somebody
When being set to " presence ", the first eNB triggering X2 Establishing process, to the 2nd MME under twoth eNB adjacent with the first eNB send X2
Request message is set up, the parameter for setting up Request carryings in request message in X2 is also constant (specific as shown in table 5), the 2nd eNB
Receive X2 to set up after request message, set up in X2 in response message and carry the Relative MME S10 list (tools of its own
Body is as shown in table 6), i.e., notify the 2nd MME S10 interface connections to the first eNB, the first eNB, which receives X2 and sets up response, to disappear
After breath, parsing record has the 2nd MME Relative MME S10 list of S10 interface connections, then is preserved with local
The Relative MME that the record that issues of response has the first MME S10 interface connections are set up by S1 by the first MME
S10 list, are contrasted, if recorded in two lists in have overlapping, that is, show to deposit between the first MME and the 2nd MME
In the connection of S10 interfaces, the first eNB and the 2nd eNB neighbor cell relation are successfully established；If record has content not in two lists
It is overlapping, then network configuration personnel are pointed out, the first eNB and the 2nd eNB neighbor cell relation have risk.
Wherein, X2 sets up request message (X2Setup Request) and X2 sets up response message (X2Setup
Response) parameter carried has new addition, with the addition of Relative MME S10 list.
And the first eNB will determine to allow UE to exist when knowing between the first MME and the 2nd MME that there is S10 interfaces connects
Inter-MME switching flows are triggered between first MME and the 2nd MME.

(X2Setup Request parameter lists)
Table 6
(X2Setup Response parameter lists)
On the other hand, can be timely if the first eNB has found that the connection of S10 interfaces is not present between the first MME and the 2nd MME
Exactly to configuration personnel's prompting this case, configuration personnel's time update network configuration parameters are made, to meet the use of terminal
Demand, without as prior art, rule of thumb judging when inter-MME switching flows are stagnated, then by staff
Whether cause this case due to being connected in the absence of S10 interfaces, so as to effectively increase the accuracy of fault location, carry
The high solution efficiency of failure.
