The technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
In order to avoid eNodeB and SGW link it is obstructed caused by user can not normal use business situation, the present invention is real
It applies example and provides a solution, mainly MME equipment is improved, increase the administrative mechanism of equipment, according to eNodeB's
Feedback, when the current device address SGW unavailable (i.e. eNodeB and the SGW device link are obstructed), MME be in time eNodeB more
The device address SGW renewed makes eNodeB establish connection with SGW equipment as soon as possible, complete user's attachment, provides industry for user
Business.
Embodiment one
It is illustrated in figure 2 the selection method of SGW equipment provided in an embodiment of the present invention, comprising:
Step 201, multiple configurations comprising the device address SGW are obtained and save, from current priority highest or minimum
The corresponding device address SGW is selected to be sent to base station by the priority orders of the device address SGW in configuration.
The device address SGW that MME is supplied to eNodeB can obtain in several ways.For example, obtained to DNS query,
Obtained to HOSTFILE list query etc..Correspondingly, multiple configurations, such as DNS configuration, HOSTFILE column are maintained on MME
Table configuration etc..Priority is arranged to this multiple configuration in the embodiment of the present invention, in this way, can achieve the configuration of different modes acquisition
The purpose mutually protected.Also priority is arranged to the device address SGW for including in each configuration respectively in the embodiment of the present invention.
It is configured for example, obtaining the DNS comprising the device address SGW by DNS query, and, it is looked by HOSTFILE list
It askes and obtains the HOSTFILE list configuration comprising the device address SGW.DNS configuration preference level can be set higher than HOSTFILE list
Configuration.Priority, referred to as the first address priority, to HOSTFILE list configuration are arranged to the device address SGW in DNS configuration
In the device address SGW be arranged priority, referred to as the second address priority.
It should be noted that by different modes obtain configuration in include the device address SGW be it is identical, still,
Difference configures corresponding address priority and is different.It is assumed that by taking the device address SGW is IP address as an example, DNS configuration and
The IP address for including in HOSTFILE list configuration has: IP1, IP2, IP3, IP4, wherein it is excellent that DNS configures corresponding first address
First grade are as follows: IP1, IP2, IP3, IP4；Corresponding second address priority of HOSTFILE list configuration are as follows: IP4, IP3, IP2,
IP1。
Current priority highest can be selected from the highest configuration of current priority according to priority at current time
The device address SGW be sent to base station.It is of course also possible to select current priority minimum from the minimum configuration of current priority
The device address SGW be sent to base station.As long as when guaranteeing subsequently selected configuration with herein according to identical priority (from high to low
Or from low to high), selection the device address SGW when with herein according to identical priority (from high to low or from low to high).
Step 202, the obstructed mistake of link between SGW equipment that is using the current device address SGW that is receiving base station feedback
False information records this mistake, and updates the errors number and the current priority highest or most of the current device address SGW
The total errors number in all device addresses SGW in low configuration.
User terminal is in attaching process, if the S1-U user face link of eNodeB and SGW is obstructed, this time adheres to meeting
Failure, while eNodeB can carry error reason in the message to MME, MME records current mistake.MME needs to update the SGW
The corresponding errors number in device address, meanwhile, MME also needs to update the device address pair SGW all in currently used configuration
The total errors number answered.
For example, DNS configuration preference level is higher than HOSTFILE list configuration, DNS configures corresponding first address priority are as follows:
IP1, IP2, IP3, IP4；Corresponding second address priority of HOSTFILE list configuration are as follows: IP4, IP3, IP2, IP1.Currently make
It is configured to DNS configuration, currently used address is IP2.After MME receives this error message, local error is recorded, more
All corresponding total errors numbers in the device address SGW in the new corresponding errors number of IP2 and DNS configuration.It is assumed that receiving this
Before secondary error message, the errors number of IP2 is that configure corresponding total errors number be 16 to 6, DNS, then after update, the mistake of IP2
It is 17 that accidentally number, which is the corresponding total errors number of 7, DNS configuration,.
Step 203, the errors number in the current device address SGW reaches preset threshold and total errors number does not have
When reaching preset threshold, the device address SGW of next priority is sent to base station in selection current-configuration；In total mistake
When number reaches preset threshold, assert that current-configuration is insincere, select SGW according to priority from the configuration of next priority
Device address is sent to base station.
The errors number of total errors number and the device address SGW for configuration, can be respectively set threshold value Y and threshold X.
After MME receives the error message of base station return each time, the errors number for judging the device address SGW is required
Whether the total errors number for whether reaching threshold X and configuration reaches threshold value Y, and the result judged includes following several:
One, when the errors number of the device address SGW does not reach preset threshold X and total errors number does not reach
When preset threshold Y, reselects the current device address SGW and be sent to base station.
Two, when the errors number of the device address SGW reaches preset threshold X and total errors number does not reach preset threshold Y
When, the current not available information in the device address SGW is broadcasted in the pond this MME, meanwhile, it selects next excellent in the current-configuration
The device address SGW of first grade is sent to base station.
In this case, when occurring if there is new attachment, all MME will not send the SGW to eNodeB and set in the pond MME
Standby address, i.e., no longer to the SGW equipment initiation carrying request for using this address, then with using the SGW equipment of next priority
Location.Under the situation, which can also be added blacklist, i.e., the device address SGW is labeled as blacklist；When
So, subsequent if it is confirmed that the corresponding SGW equipment in the device address SGW reverts to available, then can cancel the device address SGW
Blacklist label, which can be selected again.
Three, total errors number reaches preset threshold Y (regardless of whether the errors number of the device address SGW reaches preset threshold
X), assert that current-configuration is insincere, be sent to base according to the priority selection device address SGW from the configuration of next priority
It stands.
The numerical value of above-mentioned threshold values X, Y can be configured according to the actual situation.
Assuming that the priority of configuration are as follows: based on DNS configuration, supplemented by HOSTFILE list configuration.DNS configuration corresponding first
Address priority are as follows: IP1 ﹥ IP2 ﹥ IP3 ﹥ IP4；Corresponding second address priority of HOSTFILE list configuration are as follows: IP4 ﹥ IP3 ﹥
IP2 ﹥ IP1.Threshold values X is set as 10 times, and threshold values Y is set as 20 times.
For situation one, it is assumed that it is currently used be configured to DNS configuration, currently used address is IP1, after update, IP1
Errors number be 9 (are less than threshold value 10), total errors number of DNS configuration was 9 (being less than threshold value 20), then MME continues to select
IP1 is sent to base station；Assuming that it is currently used be configured to DNS configuration, currently used address is IP2, after update, the mistake of IP2
Accidentally number was 6 (being less than threshold value 10), and total errors number of DNS configuration was 16 (being less than threshold value 20), then MME continues to select IP2
It is sent to base station.
For situation two, it is assumed that it is currently used be configured to DNS configuration, currently used address is IP1, after update, IP1
Errors number be 10 (reaching threshold value 10), total errors number of DNS configuration was 10 (are less than threshold value 20), if that having new
When attachment occurs, all MME will not send IP1 to eNodeB in the pond MME, and MME selects next from high to low according to priority
The address of priority, i.e. IP2 are sent to base station.Meanwhile blacklist is added in IP1 by MME, broadcasting IP1 in the pond this MME can not
With.
For situation three, it is assumed that it is currently used be configured to DNS configuration, currently used address is IP2, after update, IP2
Errors number be 10 (reaching threshold value 10), DNS configuration total errors number be 20 (reaching threshold value 20), then MME thinks this
DNS configuration is insincere, then configuration, the i.e. HOSTFILE list configuration of next priority is selected to press when there is new attachment
From high to low according to priority, first selection IP4 is sent to base station.It is assumed that threshold value Y is 15 times, after update, the errors number of IP2 is 5
(being less than threshold value 10), total errors number of DNS configuration were 15 (reaching threshold value 15), then MME thinks that DNS configuration is insincere,
Then select configuration, the i.e. HOSTFILE list configuration of next priority, when there is new attachment, according to priority from height to
It is low, first IP4 is selected to be sent to base station.
It should be noted that threshold values Y should not be more excessive than threshold values X setting, otherwise, user terminal adheres to failure under the base station
Number can increase, influence user experience.
In addition, MME triggers alarm immediately, it is desirable that system manager exists when the MME configuration saved is all considered to insincere
Increase one or more new device addresses SGW in multiple configurations manually.It, can when increasing multiple new device addresses SGW
Priority is arranged to this multiple device address SGW, MME selects the new device address SGW to be sent to base station according to priority, together
When, MME can also empty original blacklist automatically.
Embodiment three
Illustrate the selection course of SGW equipment this embodiment offers a specific example, as shown in Figure 3, comprising:
Step 1, user carry out attach request, and MME obtains the IP address list comprising SGW equipment by inquiry DNS
DNS configuration, IP address therein arrange from high to low according to priority are as follows: IP1, IP2, IP3, IP4.Meanwhile MME also passes through
HOSTFILE list carries out the HOSTFILE list configuration that configuration obtains the IP address list comprising SGW equipment, IP therein
Address arranges from high to low according to priority are as follows: IP4, IP3, IP2, IP1.The priority of DNS configuration is higher than HOSTFILE list
Configuration.
Step 2, MME select the IP1 of highest priority to initiate carrying to SGW from DNS configuration and establish request (Create
Session Request)；SGW establishes response (Create Session Response) message by carrying and mentions to MME informing
Supply GTP link IP address, the i.e. IP1 of eNodeB access；MME passes through initialization context request (Initial Context
Setup Request) message notifies IP1 to eNodeB；
Step 3, eNodeB detect IP1, if it find that the path GTP is unreachable, execute step 4, otherwise, execute existing
Some subsequent attachment flow process.
Step 4, eNodeB pass through initialization context response (Initial Context Setup Response) message
It carries with the obstructed error reason of SGW link to MME；
After step 5, MME receive error reason, the secondary mistake is recorded for IP1, and update the errors number and DNS of IP1
Total errors number of configuration, and judge whether the errors number of IP1 reaches total errors number of threshold X and DNS configuration respectively
Whether threshold values Y is reached, if not up to threshold X, not up to threshold value Y, returns to step 2, continue to use IP1；If reached
To threshold X, not up to threshold value Y executes step 6；If reaching threshold value Y, step 7 is executed.
If step 6 reaches threshold values X, not up to threshold value Y, then all MMEs broadcast IP1 of the MME into the pond this MME can not
With (blacklist is added in IP1), when if there is new attach request, request no longer is established to using the SGW of IP1 to initiate carrying,
Then using IP address, the i.e. IP2 of next priority, request is established to using the SGW of IP2 to initiate carrying；SGW is built by carrying
Vertical response message informs GTP link IP address, the i.e. IP2 for being supplied to eNodeB and accessing to MME；MME passes through initialization context
Whether IP2 is notified then to return to step 3, i.e. eNodeB to eNodeB and detects the path SGW of IP2 by request message may be used
It reaches.
If step 7 reaches threshold values Y, it is believed that currently used DNS configuration is insincere, is changed to using HOSTFILE list
Configuration establishes request to using the SGW of IP4 to initiate carrying；SGW establishes response message by carrying and is supplied to MME informing
GTP link IP address, the i.e. IP4 of eNodeB access；MME notified IP4 to eNodeB by initialization context request message,
Then return to step 3, i.e. eNodeB detect IP4 the path SGW it is whether reachable.
Step 8, the priority according to configuration, when all configurations think insincere, then MME triggers warning information,
It asks system manager to increase new SGW IP address manually in DNS configuration or HOSTFILE list configuration, increases newly manual
SGW IP address after, MME empties the blacklist of original management using the address SGW that newly increases automatically.
Above-described embodiment can be seen that scheme proposed by the present invention through the invention, based on DNS configuration, HOSTFILE column
The priority of table configuration is different, broadcasts (notice MME to the judgment mechanism (threshold values X, threshold values Y) of current erroneous, mistake in conjunction with MME
Remaining MME in pond), mistake manages (abandon the IP for currently leading to mistake), and (all configuration can not for unrecoverable failure alarm prompt
With) etc. modes, achieve the purpose that system oneself solves mistake, realizes self-healing, automatic fast quick-recovery failure.
