| 80.1.2.2 | 40% | |
| 2 | 80.1.3.2 | 50% |
| 80.1.4.2 | 50% |
In table 1, MSISDN indicates that mobile contracted user international (Mobile Subscriber International) is comprehensive
Close service digital network (Integrated Service Digital Network, abbreviation ISDN) or Public Switched Telephone Network
(Public Switched Telephone Network, abbreviation PSTN).
The first row of table 1 indicates that IMSI is these users of 12345678xxx, in this case, due to only needing basis
IMSI selects gateway, therefore, indicates MSISDN with " * " number without the MSISDN for paying close attention to these users, thus in table 1.For this
A little users, preferred mobile gateway group are 1, correspond to table 2, due to the load balancing ratio for the gateway that IP address is 80.1.1.2
Example is 60%, and the load balancing ratio for the gateway that IP address is 80.1.2.2 is 40%, and therefore, expression can be with 3:2
Ratio selects above-mentioned two gateway for these users, i.e., 60% user selects IP address for the gateway of 80.1.1.2,40%
User selects IP address for the gateway of 80.1.2.2.
Second row of table 2 indicates that IMSI is 12345678901 user, for the user, preferred mobile gateway group
It is 2, corresponds to table 2, since the load balancing ratio of gateway that IP address is 80.1.3.2 is 50%, and IP address is
80.1.4.2 the load balancing ratio of gateway is 50%, since the load balancing ratio of the two gateways is identical, can be with
According to the business of the user, it is selected as according to 50% to 50% and selects gateway, for example, 50% service selection IP address is
80.1.3.2 for gateway as preferred gateways, remaining 50% service selection IP address is the gateway of 80.1.4.2 as preferred net
It closes.
S203, the location update request message that MME is sent is received.
The description of the step is identical as step S101, and details are not described herein again.

The IP address insertion position for the gateway selected updates in response message, and sends it to MME, by MME according to above- mentioned information, directly
For the corresponding gateway of designated user.
If S206, the gateway information for not inquiring user, location updating response message is sent to MME.
Specifically, if not inquiring the gateway information of user in the preset database, then it represents that be not user selection
Therefore the demand of preferred gateways directly can send location updating response message to MME.The operation in the prior art, HSS
After generating location updating response message according to location update request message, send it to MME be it is identical, it is no longer superfluous herein
It states.
It should be noted that can be user according to step S201~S206 for the user not yet initially adhered to
Gateway is selected, and in initial attachment, not yet being preserved in above-mentioned presetting database for selecting preferred net for the user
The information of pass, i.e. corresponding relationship between the identity and gateway information of the user, alternatively, initial attached for having been completed
User, whether no matter the user is in initial attachment, save in above-mentioned presetting database and select preferred net for the user
The information of pass, by step S201~S202, has updated the identity mark of the user after user's attachment again in presetting database
Know the corresponding relationship between gateway information, then, it just needs to migrate gateway for the user at this time.Specifically, can first to
MME sends cancel location message, which is used to indicate MME and carries out canceling position operation to user, and MME is being received
After the cancel location message, attachment removal process is initiated to the user, user can be adhered to again at this time, i.e., send to MME
Initial attachment message, after MME receives the initial attachment message, the gateway that user can be carried out according to step S203~S206 is selected
It selects, method for selecting gateway at this time selects the method for gateway identical with for the user that initially adheres to.Optionally, in 3GPP TS
In 29.27 agreements, which can be CancelLocationRequest message.
The application of above-mentioned method for selecting gateway in practice is illustrated with specific example below.
For example, being disposed in gateway features under not reciprocity scene, that is, there are some gateways, i.e., deploy new spy in local gateway
Property, and do not have on other gateways, then, for each user with same group attribute, wherein there is a certain user to contract
New features, and the new features need local gateway it is online or operation, for example, only in Virtual User gateway (Virtual
Unified Gateway, abbreviation UGW) characteristic such as key acceleration (TurboButton) or built-in based on service has been opened above
The service chaining (ServiceChain) of routing (Service Based Routing, abbreviation SBR), and storage UGW, i.e., do not use
These new features are not disposed on the UGW of virtualization technology, in order to really run these characteristics, just needing at this time will signing
The user of value-added service (Value Added Servic, abbreviation VAS) business in TurboButton or ServiceChain
It moves on corresponding vUGW.
Specifically, firstly, user passes through business support system by access portal website (Portal) or operator
(Business Support System, abbreviation BSS) interim (Provision) system, completes customer service signing, for example use
TurboButton business is ordered to TurboButton server (Server) in family, later from service management service node to ability
Open gateway issues signing information, and signing information here is the identity of above-mentioned user and the gateway information of user, so
Afterwards, which is synchronized in presetting database by the open gateway of ability, later, due to the user have been completed it is initial attached
, i.e., specified gateway is selected for it via MME, then just needing at this time will be on the corresponding gateway transport to vUGW of the user.
Specifically, the open gateway of ability can request to initiate canceling position renewal process to HSS, such as while issuing signing information
Fruit HSS do not support, can also be with short massage notice user, re-attaching network；If HSS initiates canceling position mistake by HSS
Journey, instruction user need to be adhered to again；User sends attachment message when adhering to again, to MME, and MME receives attachment and disappears
After breath, it can be selected according to the gateway for described in step S203~S206, carrying out user.Herein, user sends when adhering to again
Adhere to message, sends initial attachment message in initial attachment with user, it is identical to request to carry out the process under location updating.
