The grouping system (Evolved Packet System, EPS) of evolution is one and supports ambulant system between multiple access technology and multiple access.Under multiple access scene, under subscriber equipment (User Equipment, UE, also known as terminal) may be in the common covering of multiple third generation partner program (3rd Generation Partnership Project, 3GPP) and/or non-3 GPP access network.These access networks may use different access technologies, may belong to different operators, also may be provided to the access of different core network.With universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS)/Long Term Evolution (Long Term Evolution, and WLAN (Wireless Local Area Networks LTE), WLAN) network scenarios coexisted is example, in the base station range of UMTS/LTE, there is the access point (Access Point, AP) of multiple WLAN, the coverage of access point is relative to less base station.

Under above-mentioned network scenarios, UMTS/LTE network utilisation WLAN carries out shunting (offload).Offload is divided into seamless shunting (seamless offload) and seamed shunting (non-seamless offload).Wherein, seamed shunting refers to and does not connect between WLAN and 3GPP core net (Core Network, CN), after shunting of eating dishes without rice or wine, and the direct accessing Internet of business data flow (Internet), without 3GPP CN.

The main thought of Offload is similar to the switching flow of 3GPP internal system, evolved base station (eNB) or radio network controller (Radio Network Controller, considering RNC) according to measurement result and other factors, the business datum of UE is determined to be diverted to WLAN AP, then send switching command to UE, UE performs shunting and sends to eNB or RNC and confirms.

When WLAN AP is without 3GPP gateway, be directly connected with Internet, then this WLAN AP supports seamed shunt mode.The seamed point of service disconnection causing some servers (server of such as operator) to provide that fails to be convened for lack of a quorum.In prior art, also there is no corresponding solution.

Summary of the invention

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

The object of the invention is to be achieved through the following technical solutions:

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

The access network control node of the first access technology is adopted to determine the access point needing the business data flow of terminal to be diverted to employing second access technology;

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

Different by the executive agent shunted owing to determining the carrying which business data flow is corresponding, or indicate carrying corresponding to which business data flow different by the message form shunted, the information of carrying in switching command is also different.Illustrate below:

The first switching command: the identification information carrying carrying to be shunted in carrying corresponding to the business data flow of above-mentioned terminal in this switching command.Wherein, carrying to be shunted selects the carrying outside carrying that this access network control node is corresponding from the business data flow between terminal with particular server.The carrying that business data flow between terminal with particular server is corresponding can inform access network control node by core net node or above-mentioned terminal.The carrying that business data flow between terminal with particular server is corresponding also can be that this access network control node is determined by the business data flow of resolving this terminal.

In the embodiment of the present invention, particular server be different access technologies network between shunting cause the server of service disconnection.The particular server below occurred incites somebody to action no longer repetition of explanation.

The second switching command: the identification information carrying carrying to be shunted in carrying corresponding to the business data flow of above-mentioned terminal in this switching command.The identification information core net node of this carrying to be shunted sends to access network control node, does not wherein comprise the carrying that business data flow between this terminal with particular server is corresponding.

Based on the first switching command and the second switching command, due in carrying to be shunted, there is no the carrying that the business data flow between terminal with particular server is corresponding, make terminal when performing shunting process, be retained in by business data flow between particular server in the network of employing first access technology, the access point that the business data flow between avoiding particular server is diverted to employing second access technology causes service disconnection.

The third switching command: carry in this switching command and be used to indicate terminal not to the indication information that the business data flow in business data flow and between particular server is shunted.

Because access network control node sends not to the indication information that the business data flow between particular server is shunted to terminal, make terminal when performing shunting process, be retained in by business data flow between particular server in the network of employing first access technology, the access point that the business data flow between avoiding particular server is diverted to employing second access technology causes service disconnection.

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

Implementation one: access network control node receives the Business Stream attribute information of the terminal carrying corresponding with the business data flow between particular server that core net node sends, this Business Stream attribute information is used for informing that this carrying is the carrying that business data flow between terminal with particular server is corresponding to access network control node.This Business Stream attribute information is that core net node sends after the carrying that above-mentioned terminal is corresponding with the business data flow between particular server is set up or upgraded.

Further, access network control node can record and be carried as carrying corresponding to business data flow between this terminal with particular server accordingly.

Implementation two: the Business Stream attribute information of the carrying that the business data flow between this terminal with particular server that the above-mentioned terminal that access network control node reception opens Business Stream attribute reporting functions sends is corresponding.Wherein, this Business Stream attribute information is that the carrying that the business data flow of this terminal between its with particular server is corresponding is set up or upgrades rear transmission.

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

Based on any embodiment of the first switching command above-mentioned, after determining to need that the business data flow of terminal is diverted to the access point of employing second access technology, before sending switching command to terminal, access network control node can be corresponding according to the business data flow between this terminal with particular server received the Business Stream attribute information of carrying, determine the carrying that business data flow between this terminal with particular server is corresponding; From the carrying that the business data flow of this terminal is corresponding, select carrying outside carrying that the business data flow between this terminal with particular server is corresponding as carrying to be shunted.

As mentioned above, for the access point being configured to seamed shunt mode, if the service distributing provided by particular server is to this access point, service disconnection can be caused.After shunting terminates, a kind of situation is, terminal cannot access this particular server by access point, namely cannot by the business data flow between this access point transmission terminal and particular server.Another kind of situation is, terminal still can access this particular server by access point, but need the business data flow again between transmission terminal and particular server, make some need to ensure that the service of business continuity or the service (as breakpoint transmission) of specific function cannot realize, can Consumer's Experience be affected.For the first situation, if user does not need to continue access particular server, the service distributing that also particular server can be provided is to this access point.For the second situation, if user does not mind the service experience decline that service disconnection causes, the service distributing that also particular server can be provided is to access point.So, based on any embodiment of the first switching command above-mentioned, access network control node can also receive the third notice information of this terminal to report, and this third notice information is used for notifying whether this terminal allows shunting between the network of different access technologies to cause service disconnection to receiving terminal.When terminal does not allow to shunt between the network of different access technologies and causes service disconnection, to select carrying to be shunted the carrying outside the carrying that access network control node is corresponding from the business data flow between this terminal with particular server.

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

If the RNC in UMTS network, its base station (NodeB) particular by terminal access sends switching command to terminal.

For the third switching command, indication information wherein can be explicit information, such as, be made up of 1 bit, carrys out indicating terminal do not shunt the business data flow in business data flow and between particular server by the value configuring this 1 bit.

Indication information can also be implicit information, such as, information target access being configured to seamed shunt mode as indication information and/or using the address information of particular server as indication information.Wherein, if determine to be diverted to which access point by access network control node, so, namely this target access refers to this access point determined.If determine to be diverted to which access point by terminal, so, this target access both can refer to an access the candidates that network control node sends to terminal in switching command, and also can refer to has overlapping access point with access network control node coverage.

In the embodiment of the present invention, for this implicit information, specific implementation has multiple.Illustrate below:

Access network control node can arrange 1bit information in hand off signaling, and namely this 1bit information inform that target access is configured to the information of seamed shunt mode.In this case, access network control node can also carry specific server addresses information in hand off signaling.

Access network control node also can arrange address information territory in hand off signaling, if carry specific server addresses information in this address information territory, then the information the business data flow in business data flow and between particular server not shunted as indicating terminal of this information or as informing that target access is configured to the information of seamed shunt mode.

Such as, the identification information of each carrying of setting up or upgrading, after the carrying that the business data flow of above-mentioned terminal is corresponding is set up or upgraded, can be sent to access network control node by core net node.So, above-mentioned Business Stream attribute information can be carried in this signaling simultaneously.Concrete, 1 bit information that can be associated by the identification information of the carrying corresponding with the business data flow between terminal with particular server carries above-mentioned Business Stream attribute information.

Concrete example is as follows:

When the dedicated bearer that core net node initiates UE set up and amendment time, PGW(PDN Gateway) and SGW(Serving Gateway) carrying that issues sets up in signaling, the needs indication information carrying particular bearer as required.Request/bearer update request (Create Bearer Request/Update Bearer Request) signaling is set up in the carrying of such as PGW->SGW, all need in the Create Bearer Request/Update Bearer Request signaling of SGW->MME to expand new territory, whether in order to indicate this carrying to be the carrying that Business Stream between terminal with particular server is corresponding, the mode of instruction can represent nonspecific carrying and particular bearer respectively by 0 of 1bit and 1 value.Also can design an optional territory, indicate that when this territory occurs this is carried as particular bearer (carrying that the Business Stream between terminal with particular server is corresponding), otherwise be nonspecific carrying.Or enumerate identification information corresponding to all particular bearer (ID) with a new listing field.Mapping relations between UE business data flow and carrying both can be determined by PGW, also can be determined by SGW.If determine the mapping relations between UE business data flow and carrying by PGW, then when some carryings need the business data flow comprised between terminal and particular server, PGW indicates this to be carried as particular bearer according to above-mentioned any indicating mode in Create Bearer Request/Update Bearer Request signaling, SGW after receiving the signalling, according to the instruction of this signaling, in Create Bearer Request/Update Bearer Request signaling, this is indicated to be carried as particular bearer according to above-mentioned any indicating mode.If determine the mapping relations between UE business data flow and carrying by SGW, then when some carryings need the business data flow comprised between terminal and particular server, SGW indicates this to be carried as particular bearer according to above-mentioned any indicating mode in Create Bearer Request/Update Bearer Request signaling.

Accordingly, the carrying of issuing eNB at MME is set up and is revised in signaling (such as E-RAB Setup Request/E-RAB Modify Request), also needs the indication signaling carrying corresponding particular bearer.Below for E-RAB Setup Request, three kinds of indicating modes (also corresponding to three kinds of modes of PGW, SGW) are described:

Mode 1, increase 1bit information, indicate nonspecific carrying and particular bearer respectively with 0 and 1.

E-RAB SETUP REQUEST message format is as follows:

Wherein Specfic E-RAB is for newly to add territory, and length is 1bit, and value 0 represents nonspecific carrying, and value 1 represents particular bearer.

Mode 2, increase 1bit optional information territory, with this territory do not occur and occur indicate nonspecific carrying and particular bearer respectively

E-RAB SETUP REQUEST message format is as follows:

Wherein Specfic E-RAB is the information field newly increased, and length is 1bit, and this territory does not occur, represents this and is carried as nonspecific carrying, and this territory occurs that then representing this is carried as particular bearer.

Mode 3, an increase optional listing field, comprise the E-RAB ID that all particular bearer of this UE are corresponding in this listing field.

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

Wherein Specfic E-RAB List is the information field newly increased, and comprises the list of the ID of particular bearer corresponding to UE in this territory, and this list can be empty, means that UE does not have particular bearer.

In this example, be only with MME and eNB between S1 signaling illustrate, the indication information how carrying particular bearer is described, also similar mode can be taked to upgrade for the core network signalling relating to PGW and SGW, and specifically take which kind of mode to carry out upgrading and to be determined by different standardization groups come between each signaling, different option may be there is, but do not affect whole structure.

For implementation two, terminal both can the above-mentioned information of active reporting, also can report above-mentioned information under network side triggers.Under the triggering of network side, report above-mentioned information, namely side Network Based switch control rule reports.Concrete, switch control rule mode can have following two kinds:

Common switch, namely carries indication information as switch in system message, indicate the UE of whole community whether to open UE Business Stream attribute reporting functions;

Privately owned switch, namely utilizes the mode of dedicated signaling, whether opens UE Business Stream attribute reporting functions control separately each UE.

If UE opens Business Stream attribute reporting functions, then when there is business data flow between particular server, above-mentioned information can be sent to access network control node.

In general, whether switch is opened, under depending primarily on the covering of community and around whether there is the AP of seamed distributary division administration.A kind of typical realization, an optional territory (system message mode and dedicated signaling mode all applicable) strengthened is set exactly, when this territory occurs, then represent function to open, UE needs to carry out reporting of Business Stream attribute according to the rules, if this territory does not occur, then represent reporting functions and do not open, UE performs traditional operation.

After UE opens Business Stream attribute reporting functions, UE needs to report according to its business data flow whether had between particular server, and the triggering mode reported comprises:

If reporting service stream attribute function is opened, UE newly sets up the business data flow between particular server, then UE reports the business datum stream attribute information of the carrying that this business data flow is corresponding.Change if follow-up, the carrying change such as mapped, or have the business data flow of new particular server to be mapped in other carrying, then also need triggering to report, carry out information updating.

If the existing business data flow of UE comprises the business data flow between particular server, the function of reporting service stream attribute is just opened, then UE triggers the business datum stream attribute information reporting the carrying that this business data flow is corresponding.

If the function of reporting service stream attribute is opened, the data traffic flow end of transmission between that UE has set up and particular server, because feedforward network reported the Business Stream attribute information of the carrying that this Business Stream is corresponding, therefore need again to report, this Business Stream end of transmission of informing network, relevant information can reset or reset.

If when UE switches, Target cell reporting functions switch open:

If cell-of-origin reporting functions open, then cell-of-origin need to be forwarded to Target cell about UE stream attribute information; Occur, in the moment N time, to have reported a state updating, then thought that this renewal is not correctly forwarded to Target cell if UE switches in cell-of-origin distance, UE still will report after accessing Target cell again.

If cell-of-origin reporting functions is closed, then, after UE needs to be linked into new community, again according to circumstances report.

The carrying that business data flow based on the first switching command above-mentioned and between terminal with particular server is corresponding also can be the embodiment that this access network control node is determined by the business data flow of resolving this terminal.Concrete, address information in the packet of the address information of particular server and the business data flow of this terminal compares by access network control node, if identical, then determine that the packet of this business data flow is between terminal and particular server, and mark the identification information of the carrying of its correspondence.Optionally, determining after between the packet terminal of this business data flow and particular server, its IP five-tuple feature can also marked.And in switching command, carry this IP five-tuple feature.

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

Wherein, third notice information can be made up of 1 bit, and this 1 bit, for all business data flows of terminal, causes service disconnection for whether allowing shunting between the network of different access technologies to receiving terminal notification terminal.

Third notice information can also be made up of 2 bits, wherein shunt between the network of 1 bit for different access technologies in causing and have no progeny, by the business that access point cannot transmit, whether this 1 bit is used for allowing shunting between the network of different access technologies to cause service disconnection to receiving terminal notification terminal, shunt between the network of another 1 bit for different access technologies in causing and have no progeny, by the business that access point transmits again, this 1 bit is used for notifying whether described terminal allows shunting between the network of different access technologies to cause service disconnection to receiving terminal.Accordingly, access network control node is when selecting carrying to be shunted, business data flow between terminal and particular server is needed to judge, if cannot be transmitted by access point afterwards in shunting, then access network control node does not elect the carrying of its correspondence as carrying to be shunted, if again transmitted by access point afterwards in shunting, then access network control node can elect the carrying of its correspondence as carrying to be shunted.

Third notice information also can be made up of at least 2 bits, and every bit, for the business of a type of service, causes service disconnection for whether allowing shunting between the network of different access technologies to receiving terminal notification terminal.Accordingly, access network control node is when selecting carrying to be shunted, business data flow between terminal and particular server is needed to determine its type of service, and when the 1 bit information instruction that this type of service is corresponding cannot be transmitted by access point afterwards in shunting, access network control node does not elect the carrying of its correspondence as carrying to be shunted, when the 1 bit information instruction that this type of service is corresponding is transmitted by access point afterwards again in shunting, access network control node can elect the carrying of its correspondence as carrying to be shunted.

The embodiment of the present invention does not limit the transmission of third notice information opportunity.Such as, UE just can report entering connected state, also can report when having related service again, also can report again after unlatching WLAN, also can report again after there is shunting demand, also can report again when network requires to UE, also can report when the hobby of UE changes.

In this implementation, carry out by core net node the access point which data flow to be diverted to employing second access technology by decision-making.If the network adopting the first access technology is 3GPP network, so, the core net node carrying out decision-making is PGW or SGW.

In this implementation, optionally, access network control node when sending above-mentioned first announcement information, can also inform core net node, and the initiation cause of this Signalling exchange is because target access is configured to seamed shunt mode.

Based on the embodiment of the third switching command above-mentioned, access network control node can by resolving the business data flow of this terminal, determine that the business data flow of terminal comprises the business data flow between terminal and particular server, thus send above-mentioned indication information to terminal.Concrete, address information in the packet of the address information of particular server and the business data flow of this terminal compares by access network control node, if identical, then determine that the packet of this business data flow is between terminal and particular server, and mark the identification information of the carrying of its correspondence.Optionally, determining after between the packet terminal of this business data flow and particular server, its IP five-tuple feature can also marked.And in switching command, carry this IP five-tuple feature.

As mentioned above, for the access point being configured to seamed shunt mode, if the service distributing provided by particular server is to this access point, service disconnection can be caused.After shunting terminates, a kind of situation is, terminal cannot access this particular server by access point, namely cannot by the business data flow between this access point transmission terminal and particular server.Another kind of situation is, terminal still can access this particular server by access point, but need the business data flow again between transmission terminal and particular server, make some need to ensure that the service of business continuity or the service (as breakpoint transmission) of specific function cannot realize, can Consumer's Experience be affected.For the first situation, if user does not need to continue access particular server, the service distributing that also particular server can be provided is to this access point.For the second situation, if user does not mind the service experience decline that service disconnection causes, the service distributing that also particular server can be provided is to access point.So, based on any embodiment of the third switching command above-mentioned, access network control node can also receive the third notice information (explanation of third notice information is the same) of above-mentioned terminal to report.So that when terminal does not allow to shunt between the network of different access technologies and causes service disconnection, access network control node sends the switching command carrying above-mentioned indication information to this terminal.

Access point business data flow between particular server being diverted to employing second access technology causes service disconnection, is because adopt the access point of the second access technology to be configured to seamed shunt mode.If this access point is configured to seamless shunt mode, then unnecessaryly business data flow between particular server to be retained in the network of employing first access technology.Based on above-mentioned any embodiment, preferably, access network control node also determines the shunt mode that target access configures.Concrete, the acquisition of information that access network control node can issue according to OAM or core net node and its coverage have overlapping each to adopt the deployment Schema information of the access point of the second access technology, according to the shunt mode of the deployment Schema information determination target access configuration obtained.Also can obtain according to other semi-static information interactive modes has overlapping each to adopt the deployment Schema information of the access point of the second access technology with its coverage, according to the shunt mode that the deployment Schema information determination target access of acquisition configures.

Wherein, for the restriction of target access, see the description of above-described embodiment, no longer can limit here.

Based on above-mentioned any embodiment, preferably, the carrying that the business data flow between terminal with particular server is corresponding can only for the business data flow between transmission terminal and particular server.Can ensure so as much as possible the business data flow between nonspecific server to be diverted to target access, thus alleviate the load capacity of the network of employing first access technology.Accordingly, core net node is when carrying out carrying and mapping, and by the business data flow between terminal and carrier server, and the business data flow between terminal from other servers is mapped to different carryings respectively.

Figure 2 shows that the control method shunted between the network of a kind of different access technologies that the embodiment of the present invention provides, specifically comprise following operation:

The shunting switching command that the access network control node that step 200, terminal receive employing first access technology sends, this switching command is used to indicate the access point business data flow of terminal being diverted to employing second access technology.

Step 210, this terminal carry out shunting process to business data flow, and are retained in the network of described employing first access technology by the business data flow between particular server in shunting processing procedure.

In the embodiment of the present invention, terminal can after determining to there is the business data flow between particular server, and the business data flow between deciding in its sole discretion carrier server is retained in the network of employing first access technology.Also according to the instruction of access network control node, the business data flow between particular server can be retained in the network of employing first access technology.

If the business data flow between particular server is retained in the network of employing first access technology by the instruction according to access network control node.So, different by the executive agent shunted owing to determining the carrying which business data flow is corresponding, or indicate carrying corresponding to which business data flow different by the message form shunted, the information of carrying in switching command is also different.Its specific implementation see the description of above-mentioned access network control node side embodiment of the method, can repeat no more here.

Based on the embodiment of carrying above-mentioned indication information in switching command, which business data flow can be diverted to target access according to strategic decision-making that is predetermined or that receive by this terminal.In addition, business data flow between operator can also be identified according to the particularity of the address of particular server and domain name etc., and then be retained in the network of employing first access technology.Further, terminal can also receive the terminal IP five-tuple feature corresponding with the business data flow between particular server that access network control node sends.So, in shunting processing procedure, this terminal can according to this IP five-tuple feature, determine the business data flow between terminal and particular server, and be retained in the network of employing first access technology, and do not need carrying corresponding for this business data flow to be all retained in the network of employing first access technology.This implementation is particularly useful for the business data flow in carrying both between transmission terminal and particular server, the business data flow also between transmission terminal and other servers.

Wherein, UE can report oneself about the preference information (i.e. above-mentioned third notice information) shunted in interruption to access network control node or core net node, concrete reporting schemes can be undertaken incidentally by existing signaling, such as UE capability reporting etc., also can design and report by independent signaling.

About the opportunity reported, can be side Network Based request, i.e. access network control node or the core net node preference information of asking its shunting to be interrupted to UE, after UE receives request, feeds back according to oneself state and hobby; Also can be after the switch opens reported is liked in network side support, UE is once enter connected state, just report up-to-date preference information, and when preference information changes, also the situation of change that informing network side is up-to-date, corresponding after UE changing district, preference information can be forwarded to destination node from source node, also can continue according to hobby as UE service to make destination node; Or after the switch opens reported is liked in network side support, when having special carrying in the carrying of UE, just carry out reporting and liking the renewal of change of preference information, once special carrying terminates, then UE no longer reports.

The content reported can be with 1bit information, and whether instruction UE interrupts allowing for shunting, and this 1bit information function is in whole business of UE; Or this hobby is had made to order for specific type of service according to standard gauge, and whether all the other business allow to shunt the interruption caused depends on network side algorithm.Whether report content can also be some bit information, allow to interrupt respectively for the type of service that UE is different, equally, whether its shunting of type of service be not included in reporting allows to interrupt, and depends on network side algorithm.And, in reporting at above-mentioned two kinds, further can also segment the type that shunting is interrupted, such as a part of bit is used to indicate the thorough interruption whether allowed at new network, and remains the switching that bit is used to indicate the Non-Seamless whether allowing new network.
