Embodiment two
In the EPS network architecture of the present embodiment, by PGW (PDN GateWay, packet data network gateway) obtain distributing strategy from PCRF, distributing strategy indicates the access style of all kinds of business data flow, described access style comprises shunting access and non-shunting access, after PGW to obtain the access style of all kinds of business data flow according to distributing strategy, and then in the process setting up carrying, indicate the access style of the business data flow transmitted in some carryings to base station.Refer to Fig. 2, it is a kind of flow chart realizing another embodiment of the method for business datum diverting flow of the present invention, comprises the following steps:
Step 201:PGW knows the access style of each business data flow according to distributing strategy, when the access style of the business data flow determining transmission in any one IP-CAN carrying according to the access style of each business data flow accesses for shunting, sent the establishment carrying request or amendment carrying response that include shunting mark to mobile switching centre MME by gateway SGW, described distributing strategy indicates the access style of all kinds of business data flow, described access style comprises shunting access and non-shunting access, described shunting mark indicates the access style of the business data flow transmitted in described carrying for shunting access,
So-called " shunting access " just refers to that the business data flow of user is directly linked in the routing device of packet data network by base station, such as, router in the Internet, without the core network of operator, " non-shunting access " just refers to that base station is by the core network of the business datum of user through operator, such as, SGW and PGW in core, then be linked in packet data network.
PGW can obtain described distributing strategy from PCRF, such as, when terminal is stationed a Ge Xin community, or when being switched to new community from cell-of-origin, need create session or revise existing carrying, when PGW receives the request creating session or amendment carrying, send IP CAN conversation establishing or amendment request to PCRF, PCRF carries distributing strategy in the IP CAN conversation establishing returned or amendment response.In addition, PGW self can also store distributing strategy,
Distributing strategy in PCRF can with the access style of all kinds of business data flow of mode record of list and correspondence thereof.Certainly, can also record in another manner, the record form of the embodiment of the present invention to distributing strategy does not limit.Further, which type of access style corresponding to all kinds of business data flow can be decided by the migration efficiency of user signing contract information, network condition or operator, and the embodiment of the present invention does not also limit concrete which the class access style corresponding of all kinds of business data flow.
Usually, when PGW creates carrying, business data flow identical for demand can be transmitted in same carrying equally, e.g., business data flow identical for Qos demand be transmitted in same carrying.Therefore, after PGW to know the access style of each business data flow according to distributing strategy, the business data flow with identical access style can be transmitted in same carrying, certainly, if also consider the Qos of business data flow, can also be placed on having the business data flow of identical access style with identical Qos demand in same carrying and transmit.
Such as, according to distributing strategy, PGW knows that the access style of business data flow a, b and c is for shunting access, the access style of business data flow d and e is non-shunting access, when creating carrying, if only consider access style, business data flow a, b and c are assigned in carrying 1 by PGW, are transmitted it by carrying 1, business data flow e and d is assigned in carrying 2, by carrying 2, it is transmitted.
If consider simultaneously access style and Qos, PGW by access style be the business data flow of shunting access be assigned to meet high QoS demand carrying on, or, by access style be the business data flow of non-shunting access be assigned to meet high Qos demand carrying on.
Step 202:MME sends the establishment/amendment carrying request including shunting mark to base station;
Step 203: base station, according to the instruction of described shunting mark, is shunted the business data flow transmitted in described carrying.
Shunting mark indicates the access style of the business data flow transmitted in some carryings for shunting access, base station can carry out shunting process according to existing shunting processing mode to the business data flow transmitted in this carrying, directly be linked in packet data network by the business data flow that this carrying is transmitted, the method for the embodiment of the present invention to the shunting process that base station adopts does not do concrete restriction.
Another kind of situation is, when in step 202., when the access style of each business data flow that some carryings are transmitted is non-shunting access, PGW can send by gateway SGW the establishment carrying request or amendment carrying response that include will of presumptuously failing to be sold at auction to mobile switching centre MME, this access style of presumptuously failing to be sold at auction will instruction current service data stream is non-shunting access, in step 203, MME sends the establishment carrying request including will of presumptuously failing to be sold at auction to base station, in step 204, base station is according to the instruction of will of presumptuously failing to be sold at auction, non-shunting process can be carried out to the business data flow transmitted in this carrying according to existing non-shunting processing mode, the business datum that this carrying is transmitted is flowed through core net to be linked in packet data network, the method of the embodiment of the present invention to the non-shunting process that base station adopts does not do concrete restriction yet.
Above-described embodiment is that all base stations in systems in which complete, if in the upgrading stage of system, will there is such scene: have some base stations to have separation capacity, and other base stations do not have separation capacity when all having separation capacity.In order to ensure completing smoothly of data distribution, when the access style of the business data flow transmitted in some carryings is for shunting access, need to prejudge base station and whether there is separation capacity, only when base station has separation capacity, then indicate base station to carry out shunting process to data.
Therefore, preferably, before MME sends establishment/amendment carrying request to described base station, if the access style of the business data flow of transmission is shunting access in any one IP-CAN carrying, MME judges whether base station has separation capacity, sends described establishment/amendment carrying request when having separation capacity in described base station to described base station.
Such as, can be configured with in MME this locality the information whether each base station has separation capacity, MME directly knows whether each base station has separation capacity from the information of this locality configuration.Or also can be configured with the information whether each base station has separation capacity in an external data base, MME calls the information in this external data base, and then knows whether each base station has separation capacity.
In addition, before carrying out IP operation data distribution, can also further consider whether terminal allows shunting, if terminal allows, MME can cancel base station to the shunting process of the business data flow transmitted in described carrying according to the wish of terminal.
Therefore, preferably, described method also comprises: terminal is being set up session management or set up in load bearing process to feed back self whether to allow shunting by base station to MME, and MME does not allow to cancel the shunting process of described base station to the business data flow transmitted in described carrying during shunting in described terminal.
Such as, send to the foundation of base station to carry in request at MME and include shunting mark, when carrying out wireless resource control connection reconfiguration between base station and terminal, issue in base station in the wireless resource control connection reconfiguration request of terminal and include shunting mark, terminal is known and will carry out shunting process.Further, include in terminal feedback is to the response of the wireless resource control connection reconfiguration of base station and allow mark or non-permitted mark, this permission mark indicating terminal allows shunting, and non-permitted mark indicating terminal does not allow shunting.When base station sends foundation carrying response to MME, in this foundation carrying response, comprise permission mark or non-permitted mark.Or, send to the foundation of base station to carry in request at MME and be packaged with session management request, in this session management request, include shunting mark.Base station, by decapsulation, obtains the session management request comprising shunting mark, and this session management request is sent to terminal, terminal is known and will carry out shunting process.When carrying out wireless resource control connection reconfiguration between base station and terminal, include in terminal feedback is to the response of the wireless resource control connection reconfiguration of base station and allow mark or non-permitted mark, when base station sends session management response to MME, comprise in session management response and allow mark or non-permitted mark.
By the way, when MME obtain be non-permitted mark time, MME cancels base station to the shunting process of current service data stream according to the wish of terminal, two kinds of situation: MME are wherein had to cancel base station to the shunting process that current service data stream performs, or MME cancels this triage operator before shunting process is carried out to current service data stream in base station.
If distributing strategy is formulated by PCRF, PGW obtains this distributing strategy from PCRF, before PGW obtains distributing strategy from PCRF, first whether base station is had separation capacity notice PCRF, so that PCRF formulates distributing strategy according to the content of notice.Like this, can ensure that distributing strategy that PCRF formulates considers the separation capacity of each base station, and then data distribution is completed smoothly.Simultaneously, distributing strategy due to PCRF formulation has considered the separation capacity of each base station, therefore, even if for there being some base stations to have separation capacity, and other base stations do not have the situation of separation capacity, MME is also without the need to judging whether base station has separation capacity.
Based on this, preferably, described method also comprises: before PGW obtains distributing strategy from PCRF, if indicate base station whether there is separation capacity in the establishment session of PGW reception or the request of amendment carrying, whether base station is had separation capacity notice PCRF by PGW, so that whether PCRF has separation capacity according to base station formulate distributing strategy.
Can be found out by above-described embodiment, distributing strategy indicates the access style of all kinds of business data flow, described access style comprises shunting access and non-shunting access, PGW knows the access style of each business data flow according to distributing strategy, and the access style of the business data flow transmitted in some carryings is determined further according to the access style of each business data flow, if the access style of the business data flow transmitted in this carrying is shunting access, PGW informing base station access style is shunting access, shunting process is carried out to the business data flow transmitted in this carrying as indicated in base station.
Further, carrying out informing base station access style at MME to base station transmission establishment/amendment carrying request is before shunting accesses, judge whether base station has separation capacity at MME place, when base station has separation capacity, just informing base station access style is shunting access, so that shunting process is carried out to the business data flow transmitted in described carrying as indicated in base station.
Further, terminal is being set up session management or is being set up in load bearing process to feed back self whether to allow shunting by base station to MME, so that MME can cancel base station to the shunting process of the business data flow transmitted in described carrying when described terminal does not allow shunting.
Embodiment three
A Ge Xin community is stationed below with terminal, and the separation capacity difference of each base station (has some base stations to realize data distribution in system, other base stations cannot realize data distribution) time realize business data flow split into example, describe the process of whole data distribution in detail.Wherein, distributing strategy is obtained by PGW from PCRF.Refer to Fig. 3, it is a kind of signaling process figure realizing an embodiment of the method for business datum diverting flow of the present invention, specifically comprises the following steps:
Step 301: terminal sends Attach Request message to current base station;
Step 302: current base station sends Attach Request message to MME;
Step 303:MME sends to SGW and creates conversation request message;
Preferably, whether MME can have the information of separation capacity according to this locality configuration or each base station of external data library storage, know whether current base station has separation capacity, and indicates current base station whether to have separation capacity in establishment session request.
Step 304:SGW sends to PGW and creates conversation request message;
Equally, when MME send to the establishment session request middle finger of SGW be shown with current base station whether there is separation capacity time, in the establishment session request that SGW sends to PGW also instruction have current base station whether to have separation capacity.
Step 305:PGW, after receiving establishment conversation request message, sends IP CAN session establishment request message to PCRF;
Equally, when the establishment conversation request message middle finger in step 303 and step 304 be shown with current base station whether there is separation capacity time, in the IP CAN session establishment request message that PGW sends to PCRF, also instruction has current base station whether to have separation capacity, like this, whether PCRF can have separation capacity according to current base station and formulate distributing strategy further.Distributing strategy due to PCRF formulation has considered the separation capacity of each base station, and then data distribution is completed smoothly.
Step 306:PCRF sends the IP CAN session establishment response message comprising distributing strategy to PGW;
Wherein, distributing strategy indicates the access style of all kinds of business data flow, and described access style comprises shunting access and non-shunting access.
Step 307:PGW knows the access style of each business data flow according to distributing strategy, send the establishment bearing request message including shunting mark to SGW, this shunting mark indicates the access style of the business data flow transmitted in some carryings for shunting access;
The establishment bearing request message including shunting mark is sent to MME by step 308:SGW;
Step 309:MME judges whether current base station has separation capacity;
Current, if PCRF has considered current base station when specifying distributing strategy whether have separation capacity, this step can also be omitted.
Step 310: if current base station has separation capacity, MME sends the establishment bearing request message including shunting mark to current base station, meanwhile, send session management request message to current base station, described session management request message is encapsulated in and creates in bearing request message;
Step 311: current base station is resolved and obtained session management request message, and session management request message is sent to terminal;
Step 312: complete wireless resource control connection reconfiguration process between current base station and terminal;
Step 313: current base station sends to MME and creates bearing response message;
Step 314: present terminal sends session management response message by base station to MME;
Above-mentioned steps 313 and 314 does not have strict sequencing in execution, can also first send session management response message, then sends establishment bearing response message.
Step 315: after carrying is set up, current base station carries out shunting process according to shunting mark to current service data stream;
In shunting processing procedure, base station performs NAT (NetworkAddress Translation, network address translation) operation to the uplink message of this radio bearer, is forwarded by the downlink message received on this radio bearer.
Wherein, the detailed process of NAT operation is: base station is before transmission uplink message to packet network router, and the source address modification of message terminal sent is the address of base station.Optionally, further the port numbers of amendment message be another port, and mapping relations are recorded in base station, i.e. the source address of uplink message, source port, mapping relations between amended address and port.Finally, uplink message is sent to packet network router by base station.When the opposite end of terminal sends message to terminal, the destination address of this message is the address of base station, so this message can be routed to base station, according to the mapping relations of record, base station knows this message issues which terminal, behind the address and port numbers of this message of amendment, then this message is sent to terminal.
The object adopting NAT to operate is: if do not revise the source address of the message that terminal sends, then the opposite end of terminal is when sending message to terminal, the destination address used is the source address of original terminal, and this address is PGW distributes to terminal, so message will be routed to PGW, this can cause terminal to send message is shunting, and to receive message be non-shunting, therefore, need to perform above-mentioned NAT to operate.
Step 316:MME sends to SGW and creates bearing response message;
Step 317:SGW sends to PGW and creates bearing response message.
