In order to make those skilled in the art better understand local service shunt method of the invention, below with specific implementation
Example is described in detail.
Being illustrated in figure 2 the present invention is the equipment connection schematic diagram in embodiment.In Fig. 2:
It is deployed with multiple functional entitys in the 1-N of base station, the functional entity deployment in base station 1 is only shown in Fig. 2.Specifically
, include but is not limited in base station: MAC (Media Access Control, media access control), RLC (Radio Link
Control, radio link layer control protocol), PDCP (Packet Data Convergence Protocol, packet data converge
Poly- agreement) and GTP-U (General Packet Radio Service (GPRS, General Packet Radio Service) Tunnelling
Protocol for the userplane, the GPRS Tunnel Protocol of user level), TOF (Traffic Offload
Function, local service diverter function) etc. functional entitys.TOF functional entity is between PDCP and GTP-U functional entity.
Base station is communicatively coupled by transmission network and local service server 1-N.EPC (Evolved Packet Core, evolution
Packet-based core networks) with distal end service server later it is deployed in higher network layer (such as core computer room).
Specifically, being the local service shunt method specific steps flow chart in the embodiment of the present invention referring to Fig. 3, in Fig. 3
In:
Step 301, the identification information for having established the terminal that RRC is connect with base station is obtained.
Specifically, in an embodiment of the present invention, the TOF in base station establishes RRC with terminal and connect, in establishment process or
After the completion of connection is established, TOF sends requests for identification information message to terminal, and terminal receives the message and responded, returned to TOF
Return the identification information of terminal.In an embodiment of the present invention, identification information IMSI is used for unique identification terminal.
Step 302, when obtaining terminal access local service server, the assigned address information of terminal and port information.
Specifically, in an embodiment of the present invention, when terminal and local service server carry out data interaction, in base station
Nat feature entity will be terminal distribution private address and privately owned port.Public network is the publicly-owned address of terminal distribution and publicly-owned port,
Specific distribution method can refer to the method in prior embodiment, and the present invention repeats no more.
TOF obtains address information (publicly-owned address information and private address information) and port information (the publicly-owned end of terminal
Message breath and privately owned port information).
Step 303, by address information, port information write-in local list corresponding with identification information.
Specifically, in an embodiment of the present invention, TOF is by the publicly-owned address information, private address information, publicly-owned end of terminal
In message breath, privately owned port information and the corresponding write-in local list of IMSI information, to establish the corresponding pass between above-mentioned parameter
System.
Step 304, in the case where terminal is in RRC connection status, the local service of terminal is corresponded to according to local list forwarding
Data.
Specifically, in an embodiment of the present invention, if base station receives the downlink business number of local service server transmission
According to packet (the local service data i.e. in the embodiment of the present invention), then terminal detection is local whether there is corresponding to above and below the terminal
Literary information.If it exists, it is determined that the terminal is still under RRC connection status, then base station is according to the mesh in downlink service data packet
Address (i.e. the private address of terminal) and destination port (i.e. the privately owned port of terminal), from TOF safeguard local list in, obtain
Take the corresponding publicly-owned address information of terminal and publicly-owned port information.
Then, the destination address in downlink service data packet is replaced with the publicly-owned address of terminal by base station, by destination port
The publicly-owned port of terminal is replaced with, and downlink service data packet is sent to by terminal by TOF, specifically, TOF will referring to Fig. 2
Data packet is sent to bottom functional entity PDCP etc., then sends data packets to terminal by this kind of functional entity.
Step 305, in the case where terminal is in RRC idle state, according to the local service data for corresponding to terminal, from local column
Corresponding identification information is extracted in table.
Specifically, in an embodiment of the present invention, if base station detects that the RRC connection of terminal and base station disconnects, base station
The contextual information of terminal is discharged, meanwhile, base station still saves the address information recorded in local list, port information and mark and believes
Corresponding relationship between breath.
In a preferred embodiment of the invention, the settable ageing time of operator, that is, disconnect RRC in terminal
After connection, in ageing time, base station retains the information for corresponding to the terminal in local list, if being more than ageing time, base
Correspond to the information of the terminal in deletion local list of standing.Ageing time can be configured according to the actual situation, and the present invention is to this
Without limitation.By the way that ageing time is arranged, it is possible to prevente effectively from retaining address information, port information and the mark in local list
Corresponding relationship between information and caused by problem of resource waste, effectively increase resource utilization.
Referring now still to Fig. 3, in an embodiment of the present invention, if base station receives the downlink business of local service server transmission
Data packet, and detect that terminal is in RRC idle state (specific detecting state does not repeat herein referring to step 304), then base
Destination address (i.e. the private address information of terminal) and destination port (the i.e. privately owned port of terminal stood according to downlink business terminal
Information), inquiry is with the presence or absence of in the address information corresponding relationship relevant to port information of terminal in local list.
If it does not exist, then ageing time is already expired in explanation, and base station directly abandons the downlink service data packet.
If it exists, then corresponding identification information is extracted in base station from local list.
Then, base station passes through transmission paging message triggering terminal according to the identification information extracted, and according to identification information
Initiate RRC connection establishment process.Specifically, base station sends to terminal and pages, terminal, which receives, seeks according to the identification information extracted
After exhaling, RRC connection request message is sent to base station, message is established in base station in response RRC connection, and is connected in the RRC for receiving terminal
After connecing foundation completion message, RRC is established with terminal and is connect.In an embodiment of the present invention, base station and terminal re-establish RRC company
After connecing, it is understood that there may be the case where address information and port information change.Therefore, base station is believed according to the address recorded in local list
Corresponding relationship between breath (publicly-owned address and private address), port information (publicly-owned port and privately owned port) and IMSI, detection
Whether address information changes with port information, if so, updating the corresponding relationship in local list.
After the rrc connection is established, downlink service data packet is sent to terminal by TOF.
In conclusion the technical solution in the embodiment of the present invention, acquisition is established radio resource control RRC with base station and is connect
Terminal identification information；When obtaining terminal access local service server, the assigned address information of terminal and port information；
By address information write-in local list corresponding with identification information；If being received after the RRC connection between terminal and base station disconnects
