Shown with principle, embodiments of the present invention are unrestricted in this regard.On the contrary, the reality of the present invention
The mode of applying can apply to applicable any scene.
As shown in Fig. 2 it is the implementation process diagram of data routing method provided in an embodiment of the present invention,
It may comprise steps of：
S21, reception data route requests.
Wherein, the packet for needing to be route is carried in the data route requests received.Wherein user terminal
When carrying out Operational Visit, the packet sent to service server needs to be forwarded by base station.
The data route requests that S22, basis are received judge whether current ongoing business is local industry
Business, if it is, performing step S23, otherwise performs step S25；
S23, set up local routing with local service server and be connected.
S24, by the packet received by the local routing connection route of foundation to local service server,
Flow terminates.
S25 and EPC set up the carrying of core net dedicated service；
S26, the packet received by the carrying of the core net dedicated service of foundation is routed to corresponding industry
Business server.
When it is implemented, base station, which receives data route requests, may following two situations：A kind of situation is
The data route requests for being sent to the packet of service server for user terminal and sending, it is another be for
The data route requests that service server is sent to user terminal data bag and sent.If for user terminal
The data route requests for being sent to the packet of service server and sending, usual data route requests are arrived first
Up to base station, therefore, in this case, after base station can be analyzed the data route requests received,
Judge whether the current ongoing business of user terminal is local service, if it is, directly with local industry
Business server sets up local routing connection, is received without setting up dedicated bearer to core network requests with forwarding
Packet；And for the data route requests that service server is sent to the packet of user terminal and sent,
In this case, even if the service server is local service server, because service server can not judge
Whether current business is local service, therefore, and it needs to deliver a packet to base station by core net, and
User terminal is sent to by base station, that is to say, that had built up in this case when base station receives packet
Core net dedicated service is carried.Subsequently, base station is sent to the number of service server receiving for user terminal
After the data route requests sent according to bag, if base station is if it is judged that current ongoing business is this
Ground business, then set up local routing connection, then directly pass through packet with corresponding local service server
The local routing connection route of foundation is to local service server.In order to save transfer resource, base station can
To send resource release request to MME (Mobility Management Entity, mobility management entity),
To discharge the core net dedicated service having built up carrying；Or only used in the carrying of release core net dedicated service
User data is carried, and retains control data carrying.
When it is implemented, in base station can with integrated address resolution and route translation function, based on this, step S22
In can determine whether current ongoing business be local service according to following either type：
The first embodiment, user terminal carry corresponding instruction letter in the data route requests of transmission
Breath.

There is the configured information for indicating that current ongoing business is local service, thus, can be with step S22
Configured information according to being carried in the data route requests received determines that the current ongoing business of UE is
No is local service.When it is implemented, base station can be indicated with the information of byte, for example, with " 1 "
It is local service to indicate current ongoing business, indicates that current ongoing business is not with " 0 "
Local service.Base station is after data route requests are received, if it is determined that the configured information is " 1 ", then really
Determine UE and currently entering behavior business for local service, if it is determined that the configured information is " 0 ", then can be with
It is not local service to determine that UE is currently entering behavior business.
When it is implemented, if the base station determine that it is local service to go out the current ongoing business of UE, then with
Corresponding local service server sets up local routing connection.Specifically, base station can be to local service service
Device send connection set up request, receive local service server return response message after, it is determined that with this
Ground service server sets up local routing successful connection.
If preferably, before local routing connection is set up, established core for UE net loaded,
Then current ongoing business is transferred in the connection of the local routing of foundation, i.e. UE takes with local service
The core that the packet sent between business device is no longer pass through having set up is net loaded.In order to save resources of core network,
After local routing connection is set up, the core net dedicated service carrying of UE foundation can also be released to, or
Person discharges part resources of core network, for example, only discharging the user data carrying of the UE, and retains control number
According to carrying.

It is determined that whether current ongoing business is local service.
Under this embodiment, user terminal to service server initiate Operational Visit request when, for
Family terminal carries business clothes into the packet that service server is sent and the data route requests that send
Be engaged in the corresponding URL of device, and base station parses the URL and obtains its corresponding IP address, and judges to parse what is obtained
Whether IP address is in the local service server ip address list itself prestored, if it is, can
To determine the current ongoing business of UE as local service, if it is not, then base station can determine that UE works as
Preceding ongoing business is not local service.
If the IP address that base station is obtained according to parsing determines UE, current ongoing business is local industry
Business, then in step S23, the IP address that base station can be obtained according to parsing takes in corresponding local service
Business device sets up local routing connection, and is routed to packet to be route by the local routing connection of foundation
Local service server.
So far, base station completes the local forwarding of local service packet.
