Under above-mentioned network scenarios, UMTS/LTE network is shunted (offload) using WLAN.Offload points are seamless Shunt (seamless offload) and seamed shunting (non-seamless offload).Wherein, seamed shunting refers to WLAN It is not connected between 3GPP core net (Core Network, CN), after shunting of eating dishes without rice or wine, business data flow is directly accessed mutually It networks (Internet), without 3GPP CN.

The main thought of Offload is similar to the switching flow inside 3GPP system, evolved base station (eNB) or wireless Network controller (Radio Network Controller, RNC) comprehensively considers according to measurement result and other factors, determines The business datum of UE is diverted to WLAN AP, then sends switching command to UE, UE, which is executed, to be shunted and send to eNB or RNC true Recognize.

When WLAN AP is without 3GPP gateway, directly it is connected with Internet, then the WLAN AP supports seamed divergent die Formula.Seamed shunting will lead to the service disconnection of some servers (such as server of operator) offer.In the prior art, do not have also There is corresponding solution.

Summary of the invention

The object of the present invention is to provide the control method and device shunted between a kind of network of different access technologies, to solve The problem of seamed shunting leads to the service disconnection of the servers such as operator.

The purpose of the present invention is what is be achieved through the following technical solutions:

A kind of control method shunted between the network of different access technologies, comprising:

It needs the business data flow of terminal being diverted to use using the access network control node determination of the first access technology The access point of second access technology；

The access network control node sends switching command to above-mentioned terminal.

The executing subject being split difference is carried due to determining which business data flow is corresponding, or which business indicated Data flow is corresponding to carry the message form difference being split, and the information carried in switching command is also different.It is exemplified below:

The first switching command: it is carried in the switching command to be shunted in the corresponding carrying of business data flow of above-mentioned terminal Carrying identification information.Wherein, carrying to be shunted is the access network control node between terminal and particular server It is selected in carrying except the corresponding carrying of business data flow.Business data flow between terminal and particular server is corresponding Carrying, which can be, informs access network control node by core net node or above-mentioned terminal.Between terminal and particular server The corresponding carrying of business data flow is also possible to what the access network control node was determined by parsing the business data flow of the terminal.

In the embodiment of the present invention, particular server shunts the service for leading to service disconnection between the network of different access technologies Device.The particular server appeared below will not be repeated again explanation.

Second of switching command: it is carried in the switching command to be shunted in the corresponding carrying of business data flow of above-mentioned terminal Carrying identification information.The identification information core net node of the carrying to be shunted is sent to access network control node, In do not include the corresponding carrying of business data flow between the terminal and particular server.

Based on the first switching command and second of switching command, due in carrying to be shunted, without terminal with it is specific The corresponding carrying of business data flow between server so that terminal execute shunt processing when, will be between particular server Business data flow be retained in the network using the first access technology, avoid the business datum between particular server Flow point, which is flowed to, causes service disconnection using the access point of the second access technology.

The third switching command: in the switching command carry be used to indicate terminal not in business data flow with special services The instruction information that business data flow between device is shunted.

Since access network control node does not shunt the business data flow between particular server to terminal transmission Instruction information so that terminal execute shunt processing when, the business data flow between particular server is retained in use In the network of first access technology, avoids and the business data flow between particular server is diverted to using the second access skill The access point of art causes service disconnection.

Based on the embodiment of the first above-mentioned switching command, if the business data flow pair between terminal and particular server The carrying answered is that core net node or above-mentioned terminal are informed.So, access network control node knows the terminal and special services The implementation of the corresponding carrying of business data flow between device can with but be not limited only to it is following any one:

Implementation one: access network control node receives the industry between the terminal that core net node is sent and particular server The business stream attribute information of the corresponding carrying of data flow of being engaged in, which is used to inform to access network control node should Carrying is the corresponding carrying of business data flow between terminal and particular server.The business stream attribute information is core net node What the corresponding carrying of business data flow between above-mentioned terminal and particular server was sent after establising or updating.

Further, access network control node can recorde the industry being carried as between the terminal and particular server accordingly The corresponding carrying of data flow of being engaged in.

Implementation two: access network control node receives the above-mentioned terminal transmission for opening business stream attribute reporting functions The business stream attribute information of the corresponding carrying of business data flow between the terminal and particular server.Wherein, the Business Stream category Property information to be the terminal send after the corresponding carrying of its business data flow between particular server establishs or updates.

For second of implementation, if the Business Stream end of transmission between terminal and particular server, the terminal The identification information of the corresponding carrying of business data flow of the end of transmission is also reported to access network control node and for notifying The information of the business data flow end of transmission.After access network control node receives these information, the information recorded is deleted.

Based on any embodiment of the first above-mentioned switching command, determines to need for the business data flow of terminal to be diverted to and adopt After access point with the second access technology, before sending switching command to terminal, access network control node can be according to reception The business stream attribute information of the corresponding carrying of business data flow between the terminal arrived and particular server, determine the terminal with The corresponding carrying of business data flow between particular server；From the corresponding carrying of business data flow of the terminal, selection should Carrying except the corresponding carrying of business data flow between terminal and particular server is as carrying to be shunted.

As described previously for the access point for being configured to seamed shunt mode, if the business that particular server is provided point The access point is flowed to, will lead to service disconnection.After shunting, a kind of situation is that terminal can not be accessed by access point should Particular server can not pass through the business data flow between the access point transmission terminal and particular server.Another situation Be that terminal still can access the particular server by access point, but need transmission terminal again and particular server it Between business data flow so that some services for needing to guarantee business continuity or the service of specific function (such as breakpoint transmission) are by nothing Method is realized, will affect user experience.It for the first case, can also be with if user needs not continue to access particular server The service distributing that particular server is provided is to the access point.For second situation, if user does not mind service disconnection and makes At service experience decline, can also be by service distributing that particular server provides to access point.So, based on it is above-mentioned the first Any embodiment of switching command, access network control node can also receive the third notice information that the terminal reports, the third Shunting between the network that notification information is used to notify the terminal whether to allow different access technologies to receiving end leads to service disconnection.With Just terminal does not allow to shunt between the networks of different access technologies when leading to service disconnection, and access network control node is from the terminal and special Determine to select carrying to be shunted in the carrying except the corresponding carrying of the business data flow between server.

Wherein, third notice information can be made of 1 bit, this 1 bit is directed to all business data flows of terminal, be used for Shunting between notifying the terminal whether to allow the networks of different access technologies to receiving end leads to service disconnection.Third notice information Can be made of 2 bits, wherein 1 bit for different access technologies network between shunt lead to interruption after, by access point without The business of method transmission, this 1 bit shunts between the network for whether allowing different access technologies to receiving end notice terminal to be caused Service disconnection, another 1 bit between the network of different access technologies for after shunting and leading to interruption, the industry transmitted again by access point It is engaged in, shunting between the network that this 1 bit is used to notify the terminal whether to allow different access technologies to receiving end causes in business It is disconnected.Third notice information can also be made of at least 2 bits, and every bit is directed to the business of a type of service, be used for reception Shunting between holding notice terminal whether to allow the network of different access technologies leads to service disconnection.

Step 100 is needed using the access network control node determination of the first access technology by the business datum flow point of terminal Flow to the access point using the second access technology.

For example, can be 3GPP network using the access network control node of the first access technology.Specifically, being connect using first The network for entering technology can be UMTS network, then, use the access network control node of the first access technology for RNC accordingly. Use the first access technology network can with LTE network, then, the corresponding access network control node for using the first access technology For eNB.

Wlan network can be using the network of the second access technology.Correspondingly, using the access point of the second access technology It is WLAN AP.

Step 110, the access network control node send switching command to above-mentioned terminal.

If it is the RNC in UMTS network, sends and switch to terminal particular by the base station (NodeB) of terminal access Order.

For the third switching command, instruction information therein can be explicit information, such as be made of 1 bit, pass through The value for configuring 1 bit is carried out instruction terminal and is not divided the business data flow in business data flow between particular server Stream.

Instruction information can also be implicit information, for example, the information that target access is configured to seamed shunt mode is made For instruction information and/or using the address information of particular server as instruction information.Wherein, if determined by access network control node Surely it is diverted to which access point, then, which refers to the access point determined.If determining which is diverted to by terminal A access point, then, which can both refer to the accession to the candidate that network control node is sent to terminal in switching command Access point, may also mean that has overlapping access point with access network control node coverage area.

In the embodiment of the present invention, for the implicit information, there are many specific implementations.It is exemplified below:

1bit information can be arranged in access network control node in hand off signaling, which informs target access It is configured to the information of seamed shunt mode.In this case, access network control node can also carry specific in hand off signaling Server address information.

Address information field can also be arranged in access network control node in hand off signaling, if carried in the address information domain Specific server addresses information, then the information is as instruction terminal not to the business in business data flow between particular server Information that data flow is shunted or as informing that target access is configured to the information of seamed shunt mode.

For example, core net node can will be established after the corresponding carrying of business data flow of above-mentioned terminal establishs or updates Or the identification information of each carrying updated is sent to access network control node.It is possible on being carried simultaneously in the signaling State business stream attribute information.Specifically, the corresponding carrying of business data flow between terminal and particular server can be passed through Identification information associated 1 bit information carry above-mentioned business stream attribute information.

Concrete example is as follows:

When the dedicated bearer that core net node initiates UE is established and is modified, PGW(PDN Gateway) and SGW The carrying that (Serving Gateway) is issued is established in signaling, and the instruction information of on-demand carrying particular bearer is needed.Such as Request/bearer update request (Create Bearer Request/Update Bearer is established in the carrying of PGW- > SGW Request) signaling all needs in the Create Bearer Request/Update Bearer Request signaling of SGW- > MME New domain is extended, to indicate whether this carrying is the corresponding carrying of Business Stream between terminal and particular server, is referred to The mode shown can respectively represent nonspecific carrying and particular bearer with 0 and 1 value of 1bit.One can also be designed optionally Domain is indicated when the domain occurs and this is carried as particular bearer (Business Stream i.e. between terminal and particular server is corresponding to be held Carry), it is otherwise nonspecific carrying.Or the corresponding identification information of all particular bearers (ID) is enumerated with a new listing field. Mapping relations between UE business data flow and carrying can both be determined by PGW, can also be determined by SGW.If determined by PGW Mapping relations between UE business data flow and carrying, then when some carrying is needed comprising between terminal and particular server When business data flow, PGW is according to above-mentioned any indicating mode in Create Bearer Request/Update Bearer Indicate that this is carried as particular bearer in Request signaling, SGW after receiving the signalling, according to the instruction of the signaling, Indicate that this holds according to above-mentioned any indicating mode in Create Bearer Request/Update Bearer Request signaling Carrying is particular bearer.If determining the mapping relations between UE business data flow and carrying by SGW, when some carrying needs When comprising business data flow between terminal and particular server, SGW is according to above-mentioned any indicating mode in Create Bearer Indicate that this is carried as particular bearer in Request/Update Bearer Request signaling.

Correspondingly, being established and modification signaling (such as E-RAB Setup Request/E-RAB in the carrying that MME issues eNB Modify Request) in, it is also desirable to carry the indication signaling of corresponding particular bearer.Below with E-RAB Setup For Request, illustrate three kinds of indicating modes (also corresponding to PGW, three kinds of modes of SGW):

Mode 1 increases 1bit information, indicates respectively nonspecific carrying and particular bearer with 0 and 1.

E-RAB SETUP REQUEST message format is as follows:

Wherein Specfic E-RAB is newly plus domain, length 1bit, value 0 represent nonspecific carrying, and value 1 represents spy Fixed carrying.

Mode 2, increase 1bit optional information domain, with the domain do not occur and occur to indicate respectively it is nonspecific carrying and it is specific Carrying

E-RAB SETUP REQUEST message format is as follows:

Wherein Specfic E-RAB is the information field newly increased, and length 1bit, which does not occur, represent this and be carried as Nonspecific carrying, domain appearance then represent this and are carried as particular bearer.

Mode 3 increases an optional listing field, includes all corresponding E- of particular bearer of the UE in the listing field RAB ID。

The message format of E-RAB SETUP REQUEST is as follows:

Wherein Specfic E-RAB List is the information field newly increased, includes the ID of the corresponding particular bearer of UE in the domain List, the list can for sky, it is meant that UE does not have particular bearer.

It in this example, is illustrated with the S1 signaling between MME and eNB, illustrates how the instruction for carrying particular bearer Information can also take similar mode to upgrade for being related to PGW with the core network signalling of SGW, and each signaling it Between specifically take which kind of mode to be upgraded to be determined by different standardization groups, it is understood that there may be different option, but not shadow Ring overall effect.

For implementation two, terminal can also can both be reported with active reporting above- mentioned information under network side triggering State information.Above- mentioned information are reported under the triggering of network side, i.e., are reported based on network side switch control.Specifically, switch Control mode can have following two:

Common switch carries instruction information as switch, indicates whether the UE of entire cell opens UE that is, in system message Business stream attribute reporting functions；

Privately owned switch, i.e., in the way of dedicated signaling, to each UE whether open UE business stream attribute reporting functions into Row individually control.

If UE opens business stream attribute reporting functions, there are when business data flow between particular server, Above- mentioned information can be sent to access network control node.

In general, whether switch is opened, and depends primarily under the covering of cell and surrounding is with the presence or absence of seamed distributary division The AP of administration.A kind of typical realization, the optional domain enhanced is exactly arranged, and (system message mode and dedicated signaling mode are suitable With), when which occurs, then function opening is represented, UE needs to carry out reporting for business stream attribute according to the rules, if the domain does not go out It is existing, then it represents reporting functions and does not open, UE executes traditional operation.

After UE opens business stream attribute reporting functions, whether UE needs have between particular server according to it Business data flow reported, the triggering mode reported includes:

If business stream attribute function is reported to have turned on, UE newly establishes the business data flow between particular server, then UE reports the business datum stream attribute information of the corresponding carrying of the business data flow.If subsequent change, such as mapping Carrying variation, or there is the business data flow of new particular server to be mapped in other carryings, then it is also required to triggering and reports, Carry out information update.

If the existing business data flow of UE includes the business data flow between particular server, business stream attribute is reported Function just open, then UE triggering reports the business datum stream attribute information of the corresponding carrying of the business data flow.

If the function of business stream attribute is reported to have turned on, the established data service stream between particular server of UE The end of transmission because feedforward network reported the business stream attribute information of the corresponding carrying of the Business Stream, it is therefore desirable to again It reports, the informing network Business Stream end of transmission, relevant information can reset or reset.

If Target cell reporting functions switch is opened when UE switches:

If source cell reporting functions open, source cell need to be forwarded to target about UE stream attribute information it is small Area；If UE occurs to have reported a next state to update, then it is assumed that the update is not in the moment N time in source cell distance switching Have and be correctly forwarded to Target cell, after UE access Target cell, still to report again.

If source cell reporting functions are closed, after UE needs to be linked into new cell, according to circumstances report again.

The corresponding carrying of business data flow based on the first above-mentioned switching command and between terminal and particular server It can be the embodiment that the access network control node is determined by parsing the business data flow of the terminal.Specifically, access network control The address information of particular server is compared by node processed with the address information in the data packet of the business data flow of the terminal, If identical, it is determined that the data packet of the business data flow is between terminal and particular server, and its is marked corresponding to hold The identification information of load.Optionally, after the data packet for determining the business data flow is between terminal and particular server, may be used also To mark its IP five-tuple feature.And the IP five-tuple feature is carried in switching command.

If shunting between the network of third notice Message Display Terminal permission different access technologies leads to service disconnection, that , access network control node can select carrying to be shunted according to existing implementation.

Wherein, third notice information can be made of 1 bit, which is directed to all business data flows of terminal, be used for Shunting between the network of different access technologies whether is allowed to lead to service disconnection to receiving end notice terminal.

Third notice information can also be made of 2 bits, wherein 1 bit is shunted and led between the network of different access technologies It causes after interrupting, the business that can not be transmitted by access point, this 1 bit is used to whether allow different accesses to receiving end notice terminal Shunting between the network of technology leads to service disconnection, after another 1 bit is for shunting leads to interruption between the network of different access technologies, leads to The business that access point transmits again is crossed, this 1 bit is used to notify whether the terminal allows different access technologies to receiving end Shunting between network leads to service disconnection.Correspondingly, access network control node is when selecting carrying to be shunted, for terminal and special The business data flow determined between server is judged, if can not transmit after shunting by access point, accesses net Its corresponding carrying is not selected as carrying to be shunted by control node, if transmitted again after shunting by access point, is connect Its corresponding carrying can be selected as carrying to be shunted by network control node.

Third notice information can also be made of at least 2 bits, every bit be directed to a type of service business, for Whether receiving end notice terminal allows to shunt between the networks of different access technologies to lead to service disconnection.Correspondingly, access network control system Node is when selecting carrying to be shunted, for the business data flow between terminal and particular server it needs to be determined that its service class Type, and when the corresponding 1 bit information instruction of the type of service can not be transmitted after shunting by access point, access network control section Its corresponding carrying is not selected as carrying to be shunted by point, is led to after shunting in the corresponding 1 bit information instruction of the type of service When crossing access point and transmitting again, its corresponding carrying can be selected as carrying to be shunted by access network control node.

The embodiment of the present invention is not defined the transmission opportunity of third notice information.For example, UE can be connected entering State just reports, and can also report again when with related service, can also report, can also have again after opening WLAN It is reported again after shunting demand, can also report, can also be reported when the hobby of UE changes again when network is required to UE.

In the implementation, which data flow is diverted to connecing using the second access technology come decision by core net node Access point.If using the network of the first access technology for 3GPP network, carry out decision core net node be PGW or SGW。

In the implementation, optionally, access network control node can also be informed when sending above-mentioned first notification information Core net node, the initiation cause of the Signalling exchange are because target access is configured to seamed shunt mode.

Based on the embodiment of the third above-mentioned switching command, access network control node can be by parsing the business of the terminal Data flow is determined including the business data flow between terminal and particular server in the business data flow of terminal, thus to terminal Send above-mentioned instruction information.Specifically, access network control node is by the business number of the address information of particular server and the terminal Be compared according to the address information in the data packet of stream, if identical, it is determined that the data packet of the business data flow be terminal with Between particular server, and mark the identification information of its corresponding carrying.Optionally, in the data for determining the business data flow Packet be between terminal and particular server after, its IP five-tuple feature can also be marked.And the IP is carried in switching command Five-tuple feature.

As described previously for the access point for being configured to seamed shunt mode, if the business that particular server is provided point The access point is flowed to, will lead to service disconnection.After shunting, a kind of situation is that terminal can not be accessed by access point should Particular server can not pass through the business data flow between the access point transmission terminal and particular server.Another situation Be that terminal still can access the particular server by access point, but need transmission terminal again and particular server it Between business data flow so that some services for needing to guarantee business continuity or the service of specific function (such as breakpoint transmission) are by nothing Method is realized, will affect user experience.It for the first case, can also be with if user needs not continue to access particular server The service distributing that particular server is provided is to the access point.For second situation, if user does not mind service disconnection and makes At service experience decline, can also be by service distributing that particular server provides to access point.So, based on it is above-mentioned the third Any embodiment of switching command, access network control node can also receive the third notice information (third that above-mentioned terminal reports The explanation of notification information is same as above).So as to when terminal, which does not allow to shunt between the networks of different access technologies, leads to service disconnection, access Network control node sends the switching command for carrying above-mentioned instruction information to the terminal.

Business data flow between particular server is diverted to, business is caused using the access point of the second access technology It interrupts, is because the access point using the second access technology is configured to seamed shunt mode.If the access point is configured to seamless Shunt mode, then the unnecessary business data flow by between particular server is retained in the network using the first access technology In.Based on any of the above-described embodiment, preferably, access network control node also determines the shunt mode of target access configuration.Tool Body, access network control node can have according to the acquisition of information that OAM or core net node issue with its coverage area overlapping Each access point using the second access technology deployment Schema information, determine that target connects according to the deployment Schema information of acquisition The shunt mode of access point configuration.Can also be obtained according to other semi-static information interactive modes have with its coverage area it is overlapping each The deployment Schema information of a access point using the second access technology, determines target access according to the deployment Schema information of acquisition The shunt mode of configuration.

Wherein, for the restriction of target access, it may refer to the description of above-described embodiment, no longer limit here.

Based on above-mentioned any embodiment, preferably, the corresponding carrying of business data flow between terminal and particular server The business data flow that can be only used between transmission terminal and particular server.Can guarantee so as far as possible will with it is nonspecific Business data flow between server is diverted to target access, to mitigate the load of the network using the first access technology Amount.Correspondingly, core net node carry out carrying mapping when, by the business data flow between terminal and carrier server, and Business data flow between terminal and other servers is respectively mapped to different carryings.

Fig. 2 show the control method shunted between a kind of network of different access technologies provided in an embodiment of the present invention, tool Body includes following operation:

Step 200, terminal receive the shunting switching command sent using the access network control node of the first access technology, should Switching command is used to indicate the access point being diverted to the business data flow of terminal using the second access technology.

Step 210, the terminal carry out shunting processing to business data flow, and will be with special services in shunting treatment process Business data flow between device is retained in the network using the first access technology.

In the embodiment of the present invention, terminal can be after determining the business data flow existed between particular server, voluntarily Business data flow between carrier server is retained in the network using the first access technology by decision.It can also basis Business data flow between particular server is retained in the net using the first access technology by the instruction of access network control node In network.

If the business data flow between particular server is retained in use according to the instruction of access network control node In the network of first access technology.So, the executing subject being split is carried not due to determining which business data flow is corresponding Together, or indicate that the corresponding message form being split that carries of which business data flow is different, the information carried in switching command Also different.Its specific implementation may refer to the description of above-mentioned access network control node side embodiment of the method, no longer superfluous here It states.

Based on the embodiment for carrying above-mentioned instruction information in switching command, which can be according to predetermined or receive Which business data flow is diverted to target access by strategic decision-making.Furthermore it is also possible to according to the address and domain of particular server The particularity of name etc. identifies the business data flow between operator, and then is retained on the net using the first access technology In network.Further, terminal can also receive the business number between the terminal and particular server of access network control node transmission According to the corresponding IP five-tuple feature of stream.So, in shunting treatment process, which can be according to the IP five-tuple feature, really Determine the business data flow between terminal and particular server, and is retained in the network using the first access technology, without It needs for the corresponding carrying of the business data flow to be all retained in the network using the first access technology.This implementation is outstanding It is suitable for both business data flow between transmission terminal and particular server in carrying, also transmission terminal and other servers it Between business data flow.

Wherein, UE can to access network control node or core net node report oneself about shunt interrupt in terms of happiness Good information (i.e. above-mentioned third notice information), specific reporting schemes can be carried out incidentally with existing signaling, such as UE capability reporting Deng can also design and be reported with individual signaling.

About the opportunity reported, can be based on network side request, i.e., access network control node or core net node to UE requests it to shunt the preference information interrupted, and after UE receives request, is fed back according to the state of oneself and hobby；It can also To be after the switch that network side supports hobby to report is opened, UE once enters connected state, just reports newest preference information, And in preference information variation, also the newest situation of change in informing network side, corresponding after the changing district UE, preference information It can be forwarded to destination node from source node, so that destination node can continue to be that UE is serviced according to hobby；Or work as net Network is collateral to be held after the switch that hobby reports opens, when having special carrying in the carrying of UE, just progress preference information on respond with And the update of hobby variation, once special carrying terminates, then UE is no longer reported.

The content reported can be with 1bit information, indicate whether UE allows for shunting to interrupt, the 1bit information function In whole business of UE；Or the hobby acts on specific type of service according to standard regulation, and whether remaining business allows It is interrupted caused by shunting and depends on network side algorithm.Content is reported to can also be several bit information, respectively the industry different for UE Whether service type, which allows, interrupts, and equally, whether its shunting of the type of service being not included in reporting allows to interrupt, and depends on net Network side algorithm.Also, in above two report, can also further it be segmented to the type interrupted is shunted, such as one Part bit is used to indicate whether to allow the thorough interruption in new network, and residue bit is used to indicate whether to allow new network The switching of Non-Seamless.
