Specific embodiment
Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail, it will be appreciated that described below
Bright preferred embodiment is merely to illustrate and explain the present invention, and is not intended to limit the present invention.
The present invention provides a kind of method first embodiment for determining user plane link, and the method is applied to MME
In.As shown in Fig. 2 methods described includes：
Step 201：Obtain the mark of user plane link abnormal evolution base station eNodeB and gateway SGW
Know；
Here, when terminal adheres to failure, the eNodeB that the terminal is resident will send eventually to MME
End attachment failure, carries attachment failure reason value in the message, the cause value is used to indicate to send
The user plane link exception set up between the eNodeB and SGW of attachment failure.
Due to the SGW that the SGW is provided for the MME in the attaching process of current failure for eNodeB,
So MME would know that the mark of the SGW for itself being provided to eNodeB.Know when previous attachment in UE
Before request failure, the UE initiates attach request to network first, and MME reads what the UE was resident
The mark of eNodeB, or the eNodeB that the UE is resident sends to MME the mark of itself.Institute
Stating eNodeB marks can be the IP address of eNodeB distribution, can also be the pre-assigned eNodeB
Unique number in a network；SGW marks can be the IP address of SGW, can also be pre-assigned
SGW unique numbers in a network, are not specifically limited herein.
Step 202：According to the mark of the eNodeB and SGW, first list is obtained；
Here, after MME receives the terminal attachment failure of eNodeB transmissions, each transmission institute is recorded
Corresponding relation between the mark of the eNodeB and SGW that state terminal attachment failure, forms first list.
In actual applications, same MME can serve multiple eNodeB, the first row token for being formed
Record has the corresponding relation between each abnormal eNodeB of user plane link and the mark of corresponding SGW.Lift
Individual example, after the first time network attachment failure of UE, eNodeB feeds back attachment failure to MME,
First time network attachments of the failure reason value i.e. eNodeB and MME in UE will be carried in the failed message
For the user plane link between the selected SGW of eNodeB is unreachable (link is obstructed) in flow, MME
By the corresponding relation record between the mark and the mark of SGW of the inaccessible eNodeB of user plane link the
In one list.That is, when the user plane link in network occurs once unreachable, just can not by this
Corresponding relation between the mark and the mark of SGW of the eNodeB under up to link is recorded in first list simultaneously
Preserve.In this way, the first list that same MME is preserved will record multiple eNodeB with corresponding SGW
Mark between corresponding relation.
Step 203：When the attach request of terminal is received, according to first list, it is determined to and first
ENodeB sets up the SGW of normal users face link, and an eNodeB is resident by the terminal
eNodeB。
In the present embodiment, after the attach request for receiving terminal, methods described includes：Obtain the
The mark of one eNodeB；Obtain the mark of at least one gateway SGW；
Accordingly, it is described according to first list, it is determined to set up normal users face chain with an eNodeB
The SGW on road, including：What is recorded in acquisition first list is corresponding with the mark of an eNodeB
SGW is identified, and obtains first set；By the SGW at least one SGW marks and first set
Mark is contrasted, and obtains the first comparing result；According to the first comparing result, target SGW is determined, it is described
Target SGW is the SGW that normal users face link is set up with the eNodeB.
For example, when certain terminal just starts attachment failure, when initiating attach request to network side again,
MME receives the attach request of UE transmissions, and initiates inquiry request to DNS, to ask DNS to provide
At least one eNodeB that can be resident with the UE sets up the SGW of user plane link.DNS according to
TAC yards (first eight bits of the international identification code IMEI of mobile device) of the UE carried in inquiry request, it is determined that
Go out that DNS thinks at least one can the eNodeB set up user plane link SGW mark,
And at least one SGW identification feedbacks that will be determined return MME, MME receives at least one SGW
Mark.Wherein, MME obtains an eNodeB by reading the mark of the eNodeB that the terminal is resident
Mark.MME obtains the mark of at least one SGW by receiving the feedback content of DNS.DNS
In be provided with advance UE mark and be the UE service SGW mark between corresponding relation, UE
Mark can be TAC yards of UE.
If current eNodeB is eNodeB 1, the institute corresponding with eNodeB 1 is read in first list
Some SGW marks, form first set.It should be noted that can gather in the first set having
Corresponding relation between eNodeB 1 and corresponding SGW marks, it is also possible to which only set has relative with eNodeB 1
The mark of the SGW for answering, preferably the first.By at least one SGW marks and first set
SGW marks are contrasted, and can obtain following three seeds result, and the first comparing result is following three seeds result
In one of which：
When contrast is not to occur any one at least one SGW marks in the first set
When SGW is identified, the sub- result of the first contrast is obtained；At least one described in occurring in contrast is for the first set
When part SGW in individual SGW marks is identified, the sub- result of the second contrast is obtained；When contrast is described first
When occurring the whole SGW marks at least one SGW marks in set, the 3rd contrast son knot is obtained
Really.
Further,
When the sub- result of the first contrast is obtained, that is, when the first sub- result of contrast is used to characterize first collection
When not occurring any one SGW marks at least one SGW marks in conjunction, it is determined that having described
The SGW of the one of SGW marks at least one SGW marks is the target SGW.Specifically
, if found by aforementioned comparison, at least one SGW marks no that DNS is provided for MME
Individual appearance in the first aggregate, illustrates that there is the SGW network elements of these SGW marks to be not in failure or go out
The possibility of existing failure is low, and these SGW network elements (initiate the terminal of attach request again with current eNodeB
The eNodeB being resident) between the user plane link set up will be with accessibility, then these can be chosen
Any one in SGW network elements is target SGW.It is of course also possible to choose target according to certain criterion
SGW.For example, in these SGW network elements, choosing the user plane link set up with other eNodeB most
Few SGW is target SGW, and the SGW network elements that selection IP is designated A are target SGW etc., choosing
The SGW for taking highest priority is target network element.Depending on the criterion can be according to actually used situation, herein
Do not limit.
When the sub- result of the second contrast is obtained, that is, when the second sub- result of contrast is used to characterize first collection
When occurring the part SGW marks at least one SGW marks in conjunction, at least one SGW
The SGW marks not appeared in first set are filtered out in mark, it is determined that during the SGW after screening is identified
One of SGW is identified for target SGW, it is determined that the SGW with target SGW marks is institute
State target SGW.If specifically, by aforementioned comparison find, in DNS for MME is provided at least
There is part to occur in the first aggregate, illustrate to have appearance in the first aggregate this in one SGW mark
There is faulty possibility in the SGW network elements of a little SGW marks, MME does not consider these SGW network elements,
The SGW marks not appeared in first set should be filtered out, from the mark for filtering out, selection has
The SGW network elements of certain mark are target network element.It is of course also possible to choose target according to certain criterion
SGW.For example, in SGW network elements after screening, choosing the user plane chain set up with other eNodeB
The minimum SGW in road is target SGW, and the SGW network elements that selection IP is designated A are target SGW etc.,
The SGW for choosing highest priority is target network element.
It should be noted that DNS generally has low priority high, SGW for multiple SGW that MME is provided
The height of priority itself is consistent with the priority height of the mark of the SGW, and for example priority is high
SGW its mark priority it is also high.Based on this, the method for the acquisition SGW that the present invention is provided also includes：
When the mark of the acquired at least one gateway SGW has priority, when the described first collection
The SGW for occurring the part SGW marks at least one SGW marks in conjunction and occurring is designated
During limit priority, filtered out at least one SGW marks in not appearing in first set
SGW is identified, in the SGW marks after screening, it is determined that the SGW of the marks of the SGW with highest priority
It is target SGW.Specifically, in the case where the sub- result of the second contrast is obtained, if there is in first set
In SGW be the other SGW of limit priority, the priority that does not occur in first set of selection is forward
SGW is target SGW.If for example, limit priority is still present in SGW after screening
SGW, just the SGW of selection limit priority is target SGW；If do not existed in the SGW after screening
There is the SGW of limit priority and there are the SGW of time (secondary high) priority high, just selection is secondary high (secondary
It is secondary high) SGW of priority is target SGW, by that analogy.
When the 3rd sub- result of contrast is obtained, that is, when the 3rd sub- result of contrast is used to characterize first collection
When occurring the whole SGW marks at least one SGW marks in conjunction, outputting alarm information.Specifically
, as DNS for multiple SGW marks that MME is provided are both present in first set, explanation may have
Have these SGW identify SGW in one or more appearance it is faulty, or with these SGW before
The current eNodeB appearance for carrying out user plane link connection is faulty, then MME outputting alarm information,
With all connections for disconnecting with set up before current eNodeB, or current eNodeB is exited into service, or
Person's prompting is manually reconfigured in new SGW marks such as SGW IP address to DNS, with by again
Configuration operation can set up the SGW with accessibility user plane link for MME is provided with current eNodeB.
In aforementioned schemes, MME knows the mark of user plane link abnormal eNodeB and SGW, will
Both identified relationships are carried out into corresponding record, first list is formed；Follow-up MME receives certain terminal
Attach request when, the multiple SGW marks and the terminal that MME is provided according to DNS are resident
The mark of eNodeB, determines and can set up normal users face link with the eNodeB according to first list
SGW.Further, SGW marks corresponding with eNodeB marks are extracted in first list,
First set is formed, and the multiple SGW provided by DNS are identified and marked with the SGW in first set
The contrast of knowledge obtains target SGW, and target SGW can be resident by what MME was determined with the terminal
ENodeB set up the SGW of the user plane link with accessibility.In this way, just ensure that user plane chain
The accessibility on road, for UE provides guarantee in the successful attachment of network side, also ensure that the positive normal open of UE
Letter.In the present embodiment, first list is increased newly in MME, according to the content that the first list is recorded, can
Reduce the probability that MME provides the SGW that unreachable link is set up with eNodeB for eNodeB.In addition,
A kind of disaster tolerance detection of link when preceding method can also occur abnormal as user plane link and recovery side
Method.
The present invention also provides a kind of second embodiment of the method for determining user plane link, is applied to eNodeB
In.As shown in figure 3, methods described includes：
Step 301：User plane link between the eNodeB that has set up of detection and every SGW
Link State；
Here, so that the eNodeB is eNodeB 1 as an example, between eNodeB 1 and each SGW
The user plane link of foundation, the Link State of the Periodic probes of eNodeB 1 these user plane links.The link shape
State includes that user plane link is normal and abnormal two kinds.
Step 302：When the user plane link that there are Link State exception is detected, exception use is obtained
The mark of the SGW in the link of family face；
Here, when it is abnormal that eNodeB 1 detects its user plane link set up between certain SGW,
ENodeB 1 reads the mark of the SGW.
Step 303：The mark of the SGW acquired in, obtains second list；
Here, eNodeB 1 remembers the corresponding relation between the mark of itself and the mark of the SGW for being read
Record preserves second list in second list.It should be noted that the second list that eNodeB 1 is preserved
Record with the presence of between the abnormal SGW marks of the user plane link set up therewith and the marks of eNodeB 1
Corresponding relation.
For example, during the first time network attachment of UE, eNodeB 1 has found itself and MME
For the user plane link between the selected SGW 1 of eNodeB 1 is unreachable in this network attachment flow
The eNodeB of itself is identified close corresponding between the mark of SGW 1 by (link is obstructed), eNodeB1
System's record is in second list.That is, when eNodeB 1 has found itself and the use between certain SGW
When family face link occurs unreachable, just by the corresponding relation between itself eNodeB marks and SGW marks
Record is in second list and preserves.
MME thinks suitable for eNodeB 1 selects a MME in the method shown in earlier figures 2
SGW, and whether the user plane link with accessibility can be set up between this SGW and eNodeB1,
Also need to eNodeB 1 and perform step 304 and 305.
Step 304：Obtain target SGW marks；
Here, determine that it is regarded to set up accessibility user plane link with eNodeB1 in MME
After the mark (target SGW marks) of SGW, MME sends the SGW by initializing context message
Mark, eNodeB 1 receives target SGW marks.Additionally, in actual applications can also manually/
The mode for automatically configuring is pre-configured with eNodeB 1 can set up accessibility user plane link with it
The mark of SGW, eNodeB 1 knows that the SGW is identified by the content that reading is pre-configured with.
Step 305：According to the second list, determine the eNodeB whether can with the target
The SGW of SGW marks sets up normal user plane link.
Further, if eNodeB 1 is judged as target SGW, mark appears in second for itself being preserved
In list, illustrate that the user plane link between eNodeB 1 and the SGW with target SGW marks will
Without accessibility, for the initialization context message that MME sends, eNodeB 1 does not send initialization
Context response information, itself is not set up and has the user plane between the SGW of target SGW marks
Link, and the target SGW marks are abandoned, it is the SGW that eNodeB 1 is reported to wait MME next time
Mark.
During if eNodeB 1 is judged as that target SGW marks do not appear in the second list for itself being preserved,
Illustrate that the user plane link between eNodeB 1 and the SGW with target SGW marks will have reachable
Property, set up itself and there is the user plane link between the SGW of target SGW marks, for MME
The initialization context message of transmission, it is attached to complete UE that eNodeB 1 sends initialization context response information
Flow.
Additionally, if eNodeB 1 detects all states for having set up user plane link when having abnormal,
ENodeB 1 confirms itself to occur in that failure, generation alarm data, with prompting maintenance personnel.
It should be noted that the method for aforementioned applications determination user plane link in the enodeb can be independent
Use, it is also possible to first list in MME disablers and/or MME update situation not in time and
Use, i.e., as the method for the determination user plane link SGW that is applied to earlier figures 2 Suo Shi in MME
