Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of method, Mobility Management Entity, policy functional entity and user terminal of setting up carrying.
Background technology
(3rd Generation Partner Project 3GPP) has proposed System Architecture Evolution (System Architecture Evolution, SAE) project to third generation partner program.The network configuration of SAE as shown in Figure 1.Among Fig. 1, mobile line pipe reason entity (Mobility Management Entity, MME) be in core network, be responsible for mobile management, function comprises the carrying control of core net, to gateway (Serving Gateway, SGW) and PDN Gateway (PDN Gateway, PDN-GW) select authentication etc.SGW is responsible for user terminal (User Equipment, the UE) transmission of user plane data, forwarding and route switching etc.PDN-GW mainly is responsible for being connected with the PDN network, is user's distributing IP address etc."Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF) entity is responsible for CAMEL-Subscription-Information, Internet protocol ability access network according to the user (IP Capability Access Network, IP-CAN) information such as type, IP-CAN ability is produced strategy and the charging regulation information that is used to carry foundation.
SAE supports user's roaming, when the user from a Public Land Mobile Network (Public Land Mobile-communication Network, when PLMN) roaming into another one PLMN, the routing mode of user data has two kinds of selections according to user's CAMEL-Subscription-Information: a kind of is that the user's data route is returned the possession, and this mode is commonly referred to ownership place route (home routed); Another kind is that user data is exported in the roaming place, and this mode is commonly referred to local breakout (local breakout).
Fig. 2 shows the schematic diagram of home routed mode.As shown in Figure 2, the UE that is positioned at access zone network is by the PDN-GW of visit ground SGW with data route recurrence possession, and the PDN-GW by ownership place is connected to external network again.
Fig. 3 shows the schematic diagram of local breakout mode.As shown in Figure 3, the UE that is positioned at access zone network is connected to external network by the PDN-GW that visits ground again by the PDN-GW that visit ground SGW routes data to visit ground.
The main distinction of home routed and this dual mode of local breakout is the selection of PDN-GW.All media datas of UE all are connected to external network by PDN-GW.When UE adopted home routed mode, all media datas at first needed route to return the possession network; When UE adopted local breakout mode, user's media data can be directly from exporting to external network with visiting.With respect to home routed form, the benefit of local breakout is to realize the data route in the network on visit ground, and does not need to take the network of ownership place, thereby saves Internet resources.
The selection of user PDN-GW mainly be according to UE APN (Access Point Name, APN) and CAMEL-Subscription-Information.If user's CAMEL-Subscription-Information allows at roaming place network allocation PDN-GW, then distribute PDN-GW in the roaming place; If fail to find PDN-GW in the roaming place, or the PDN-GW that indication does not allow to use the roaming place network in user's the CAMEL-Subscription-Information, then in belonging area network, seek and connection PDN-GW.
Also introduce the IMS subsystem among the 3GPP.Concrete, IMS is at packet switching (Packet Switched, the subsystem that PS) superposes on the territory among the 3GPP.IMS supports UE to insert the IMS networks by various packet switching Access Networks to carry out the IMS multimedia service, and the son exchange Access Network of normal use is IP-CAN at present, and for example GPRS (General Packet Radio Service, GPRS), SAE.
Access point can be understood as between UE and selected service the ip router that is connected is provided.The example of this service such as MMS, IMS.Same access point may provide multiple above-mentioned service.UE need know to service provides entity (as MMS, IMS etc.) that the address of the APN-PDN-GW of access is provided.A PDN-GW may provide different services, can be by different APNs (Access Point Name, APN) visit.
In research and practice process to prior art, the inventor finds to exist in the prior art following problem:
Prior art only is to judge according to APN and SAE CAMEL-Subscription-Information, supports that in the SAE system UE sets up default bearing (default bearer) in the mode of local breakout, promptly selects the vPDN-GW of roaming place under the situation of local breakout.And different IMS business may need to set up default bearer in the mode of local breakout or home routed respectively.Scheme by above-mentioned prior art, according to APN and SAE CAMEL-Subscription-Information, in the SAE system, support local breakout if judge UE, then can set up default bearer in the mode of local breakout, promptly select vPDN-GW, and do not consider that concrete IMS business sets up the mode that default bearer needs.Like this, if the IMS service needed of UE request is set up default bearer in the mode of home routed, then the default bearer that sets up in local breakout mode in the prior art can not satisfy the demand, in this case, carrying between the vPDN-GW of needs dismounting and roaming place, and the carrying between foundation and the ownership place hPDN-GW.The process of rebuilding is removed in this carrying can cause the wasting of resources, makes the session elongated user experience variation that makes settling time simultaneously.

Embodiment
The embodiment of the invention provides a kind of method, Mobility Management Entity, policy functional entity and user terminal of setting up carrying.
In order to make those skilled in the art person understand the present invention program better, the embodiment of the invention is described in further detail below in conjunction with drawings and embodiments.
Need to prove that at first UE can be known the type of the IMS business that will apply in advance under following two kinds of situations at least:
1, the SAE attach of UE is by concrete IMS business-driven.Concrete, the SAE attach of UE is the request of adhering to that is caused by the IMS service request of terminal initiation.For example, under the initial condition, UE has only the connection in CS territory, there is not the PS territory to connect, in the subsequent process, UE for example initiates the request of IMS visual telephone, because UE does not also have SAE attach at this moment, therefore at first carry out SAE attach process, and then on SAE IP-CAN basis, carry out the IMS service request.
2, UE uses certain specific I MS business at every turn.
At least in the above two kinds of cases, carry out in the SAE attach process at UE, can prejudge out according to the IMS type of service that UE will apply for is needs local breakout mode or home routed mode.
Below introduce first embodiment that the present invention sets up bearing method, Fig. 4 shows the flow process of this embodiment, as Fig. 4, comprising:
S501:UE carries the APN of IMS business and IMS communication business identification (IMS Communication Service Identifier, ICSI) the initiation attach request of sign IMS communication service.
ICSI is used to identify certain concrete IMS communication service.Each ICSI can IMS business of unique identification.Every kind of IMS business has the requirement of different CAMEL-Subscription-Information and different QoS and secure context.The CAMEL-Subscription-Information here can be whether this business allows to use local breakout.When carrying out attach or initiate service request, UE can carry one or more ICSI, the IMS professional ability of using ICSI to be supported during attach with the informing network user; Use the IMS business of ICSI when initiating service request with informing network UE application.The input that ICSI can be used as PCRF is used for producing strategy and charging regulation information.PCRF can utilize ICSI to judge that the user still is the carrying of home routed mode with the carrying of the IMS service needed local breakout mode of initiation.
The ICSI here can be obtained by UE in following a, b, three kinds of situations of c:
The SAE attach of a, UE is by concrete IMS business-driven, and is concrete, and the SAE attach of UE is the IMS service request of being initiated by terminal and cause adhere to request.For example, UE initiates the request of an IMS visual telephone, because UE does not have SAE attach at this moment, therefore at first carries out SAE attach process, and then carry out the IMS service request on SAE IP-CAN basis.UE can be known ICSI information from the IMS service request.
In a word, can obtain the IMS business information, like this, when initiating to adhere to request, not have the SAE carrying, the IMS business information can be added to described adhering in the request if judge from the IMS service request of initiating.
The IMS type of service that b, UE storage UE often uses.ICSI is the IMS type of service that UE often uses.
Concrete, can write down each IMS business and the IMS business information of setting up thereof of terminal, like this, when initiating to adhere to request, can add the business information of IMS business commonly used to described adhering in the request.
The IMS type of service that c, UE storage UE acquiescence is used.ICSI is the IMS type of service that the UE acquiescence is used.
Concrete, the user can be provided with the IMS business of acquiescence, and terminal has received after the acquiescence IMS business of user's setting, when initiating to adhere to request, can add the business information of described acquiescence IMS business to described adhering in the request.
ICSI can transmission in the content territory of the content territory of IMS signaling sign (IMS Signalling Flag) or Proxy Call Session Control Function (P-CSCF) Address requests (P-CSCF Address Request).Concrete, when UE initiates default bearer foundation request, in request message, comprise protocol architecture option (Protocol configuration options) field, comprise several vessels (container) in this field, the structure of container comprises and is used for illustrating this container purposes purpose container identification (container identifier), container contents length (length of container identifier contents), the message content that container carries (container identifier content).Here said IMS Signalling flag and P-CSCFAddress Request are container identifier.In the prior art, generally, all only used container identifier for IMS Signalling flag and P-CSCF Address Request, and the content territory, promptly container identifier content is empty.In the embodiment of the invention, can be beneficial to container identifier content and transmit ICSI.
S502:MME starts the authentication ciphering process, finishes the authentication ciphering with UE and HSS.
This step is conventional authentication ciphering step, and according to the purpose that the embodiment of the invention will realize, this step can be omitted.
S503:MME initiates ICSI to be sent to HSS, with the IMS subscription information of acquisition request ICSI correspondence in the position updating request process.
S504:HSS sends to MME with the SAE CAMEL-Subscription-Information of UE and the IMS service profile of ICSI correspondence.
As previously mentioned, described SAE CAMEL-Subscription-Information comprises and sets up the needed user signing contract information of default bearing.
S505:MME returns and receives data-acknowledge message.
The S506:HSS home position upgrades acknowledge message.
S507:MME selects PDN-GW according to the CAMEL-Subscription-Information of SAE CAMEL-Subscription-Information and IMS business.Select after the PDN-GW the follow-up acquiescence connection foundation request that could be initiated to selected PDN-GW to S-GW.Suppose among this embodiment that selected is hPDN-GW.
The CAMEL-Subscription-Information and the SAE CAMEL-Subscription-Information of the MME IMS business that indication is judged according to ICSI are selected S-GW and PDN-GW.
Here, can judge in the CAMEL-Subscription-Information of the IMS business of the ICSI correspondence of UE and not support local breakout, at this moment, MME selects hPDN-GW.
Mainly be the selection of carrying out home routed or local breakout of factor during setting up carrying in the prior art, promptly select hPDN-GW or vPDN-GW from the SAE aspect.And in the embodiment of the invention one,, MME is carrying out taking all factors into consideration at least two kinds of factors when PDN-GW selects, and promptly takes all factors into consideration the IMS service profile of SAE CAMEL-Subscription-Information and ICSI correspondence at least.For example, if judging from the corresponding CAMEL-Subscription-Information of ICSI, the IMS business (being the indicated IMS business of ICSI) of UE request can select local breakout, but current UE place access zone network is not supported local breakout by the SAE CAMEL-Subscription-Information, and then MME still will select the hPDN-GW of UE ownership place.Again for example, if current UE place access zone network is by the supported local breakout of SAE CAMEL-Subscription-Information, the IMS business (being the indicated IMS business of ICSI) of UE request is simultaneously judged from the corresponding CAMEL-Subscription-Information of ICSI can not support local breakout, and then MME selects the hPDN-GW of user attaching.That is to say, when the access zone network at UE place supports that the IMS business of local breakout and UE request can local breakout, select the vPDN-GW on visit ground; The access zone network at UE place does not support the IMS business of local breakout and UE request not support local breakout yet, selects the hPDN-GW of ownership place.
After two kinds of factors of IMS service profile of taking all factors into consideration SAE CAMEL-Subscription-Information and ICSI correspondence are set up and are carried successfully, when UE really initiates the IMS service request, can set up corresponding carrying according to the IMS service request of being asked, and the situation that the carrying that can not occur setting up is not satisfied the demand, the also process that has rebulid the carrying that needs with regard to having avoided needing to remove original carrying.
Among this embodiment, provided from the IMS service profile of the ICSI correspondence of UE and judged the situation of not supporting local breakout, those skilled in the art can understand, judge needs local breakout in the CAMEL-Subscription-Information according to the IMS business of the ICSI correspondence of UE, and the SAE corresponding informance needing to obtain the situation of local breakout, then can select vPDN-GW.
S508:MME initiates to set up the default bearing request to S-GW.This carrying can be used for the transmitting SIP signaling.
S509:S-GW initiates default bearing to hPDN-GW and sets up request.
S510:hPDN-GW sets up the relevant information of default bearing to the hPCRF request.
S511:hPCRF initiates to obtain to set up the default bearing request-related information to HSS.
S511 is optional, has had in hPCRF under the situation of setting up bearer related information, and S511 can not carry out.
S512:HSS returns the relevant information of setting up default bearing to hPCRF.
To be HSS obtain the bearer related information request of setting up according to what hPCRF among the S511 sent to S512, will set up bearer related information and return to HSS.If S511 does not carry out, then S512 can not carry out yet.
S513:hPCRF will set up bearer related information and send to hPDN-GW.
S514:hPDN-GW sets up relevant information according to carrying and sets up default bearing, and sets up confirmation to S-GW transmission default bearing.
S515:S-GW sends default bearing to MME and sets up confirmation.
S516:MME sends the attach acknowledge message to the user.
S517: the user returns attach and finishes message.
By above-mentioned first embodiment as seen, UE carries the APN of IMS business and the ICSI of sign IMS communication service initiates the attach request, MME selects S-GW and PDN-GW according to the CAMEL-Subscription-Information and the SAE CAMEL-Subscription-Information of the IMS business of ICSI indication, can set up and the corresponding to carrying of IMS business demand.Particularly set up under the situation of default bearer in the mode of home routed in the IMS service needed of UE request, can set up default bearer in home routed mode, promptly select hPDN-GW to set up carrying, like this, needing in the prior art to have avoided removing and roaming place vPDN-GW between the process of the carrying of setting up, save Internet resources, reduced session settling time simultaneously, improved user experience.
Below introduce second embodiment of the inventive method, Fig. 5 shows the flow process of this embodiment, as shown in Figure 5, comprising:
S601:UE carries the APN of IMS business and the ICSI of sign IMS communication service initiates the attach request.
ICSI is used to identify certain concrete IMS communication service.Each ICSI can IMS business of unique identification.Every kind of IMS business has the requirement of different CAMEL-Subscription-Information and different QoS and secure context.The CAMEL-Subscription-Information here can be whether this business allows to use local breakout.When carrying out attach or initiate service request, UE can carry one or more ICSI, the IMS professional ability of using ICSI to be supported during attach with the informing network user; Use the IMS business of ICSI when initiating service request with informing network UE application.The input that ICSI can be used as PCRF is used for producing strategy and charging regulation information.PCRF can utilize ICSI to judge that the user still is the carrying of home routed mode with the carrying of the IMS service needed local breakout mode of initiation.
The ICSI here can be obtained by UE in following a, b, three kinds of situations of c:
The SAE attach of a, UE is by concrete IMS business-driven, and is concrete, the IMS service request that UE initiates and cause adhere to request.For example, the user initiates the request of an IMS visual telephone, because the user does not have SAE attach at this moment, therefore at first carries out SAE attach process, and then carry out the IMS service request on the SAEIP-CAN basis.UE can be known ICSI information from the IMS service request.
In a word, can obtain the IMS business information, like this, when initiating to adhere to request, not have the SAE carrying, the IMS business information can be added to described adhering in the request if judge from the IMS service request of initiating.
The IMS type of service that b, UE storage user often uses.ICSI is the IMS type of service that the user often uses.
Concrete, can write down each IMS business and the IMS business information of setting up thereof of terminal, like this, when initiating to adhere to request, can add the business information of IMS business commonly used to described adhering in the request.
C, UE storage user gives tacit consent to the IMS type of service of use.ICSI gives tacit consent to the IMS type of service of use for the user.
Concrete, the user can be provided with the IMS business of acquiescence, and terminal has received after the acquiescence IMS business of user's setting, when initiating to adhere to request, can add the business information of described acquiescence IMS business to described adhering in the request.
ICSI can transmit in the content territory of the content territory of IMS Signalling Flag or P-CSCF Address Request.Concrete, when UE initiates default bearer foundation request, in request message, comprise protocol architecture option (Protocol configuration options) field, comprise several vessels (container) in this field, the structure of container comprises and is used for illustrating this container purposes purpose container identification (container identifier), container contents length (length of container identifier contents), the message content that container carries (container identifier content).Here said IMS Signalling flag and P-CSCF Address Request are container identifier.In the prior art, generally, all only used container identifier for IMS Signalling flag and P-CSCF Address Request, and the content territory, promptly container identifier content is empty.In the embodiment of the invention, can be beneficial to container identifier content and transmit ICSI.
S602:MME starts the authentication ciphering process, finishes the authentication ciphering with UE and HSS.
S603:MME initiates position updating request to HSS.
S604:HSS sends to MME with the relevant CAMEL-Subscription-Information of SAE of UE.
S605:MME returns and receives that data-acknowledge message arrives HSS.
The S606:HSS home position updates confirmation message to MME, and so far position updating process is finished.
The ICSI that S607:MME carries APN and sign IMS communication service initiates to set up the default bearing request to SGW.
S608:S-GW initiates default bearing to vPCRF and sets up strategy request.
S609:vPCRF sends to the default policy request of receiving the hPCRF of ownership place.
S610:hPCRF initiates to obtain the request of the relevant CAMEL-Subscription-Information of ICSI to HSS.
S610 is optional, has had in hPCRF under the situation of the relevant CAMEL-Subscription-Information of ICSI, and S610 can not carry out.
S611:HSS returns the relevant CAMEL-Subscription-Information of ICSI to hPCRF.
S611 is the request of obtaining the relevant CAMEL-Subscription-Information of ICSI that HSS sends according to hPCRF among the S610, and the relevant CAMEL-Subscription-Information of ICSI is returned to HSS.If S610 does not carry out, then S611 can not carry out yet.
S612:hPCRF draws the strategy of selecting hPDN-GW or vPDN-GW to set up default bearing according to the CAMEL-Subscription-Information of user's the corresponding IMS business of ICSI.
Here, can draw in the CAMEL-Subscription-Information according to the IMS business of the ICSI correspondence of UE and not support local breakout, at this moment, hPCRF draws the strategy of selecting hPDN-GW to set up default bearing according to the information such as CAMEL-Subscription-Information of user's the corresponding IMS business of ICSI.Certainly, can draw needs local breakout in the CAMEL-Subscription-Information according to the corresponding IMS business of the ICSI of UE, at this moment, hPCRF draws the strategy of selecting vPDN-GW to set up default bearing according to the information such as CAMEL-Subscription-Information of the ICSI business of UE.
The strategy that S613:hPCRF sets up default bearing sends to vPCRF.
The strategy that S614:vPCRF sets up default bearing sends to S-GW.
S615:S-GW sends the strategy that default bearing is set up to MME.
S616:MME sets up policy selection PDN-GW according to SAE CAMEL-Subscription-Information and the default bearing that obtains, and the default bearing that is initiated to selected PDN-GW to S-GW is set up request.
MME selection SGW and prior art are similar, are according to SAE CAMEL-Subscription-Information and APN.
Mainly be the selection of carrying out home routed or local breakout of factor during setting up carrying in the prior art, promptly select hPDN-GW or vPDN-GW from the SAE aspect.And in the embodiment of the invention two, the strategy that draws from the factor of the professional aspect of IMS according to hPCRF also.MME takes all factors into consideration at least two kinds of factors in selecting hPDN-GW or vPDN-GW process, promptly take all factors into consideration SAE at least and be connected the foundation strategy with the acquiescence that obtains.For example, set up strategy and learn and to select local breakout that promptly select vPDN-GW, but do not supported local breakout by the SAE CAMEL-Subscription-Information, then MME still selects the hPDN-GW of user attaching to set up default bearing if connect by the acquiescence that obtains.Again for example, if by the supported local breakout of SAE CAMEL-Subscription-Information, connect simultaneously and set up strategy and learn and do not support promptly to select hPDN-GW by local breakout that then MME draws and selects the hPDN-GW of UE ownership place to set up default bearing by the acquiescence that obtains.That is to say that the access zone network at UE place is supported local breakout and connected by acquiescence to set up strategy and learn that can local breakout the time, MME selects the vPDN-GW on visit ground to set up default bearing; The access zone network at UE place is not supported local breakout and is connected by acquiescence to set up strategy and learn that when also not supporting local breakout, MME selects the hPDN-GW of ownership place to set up default bearing.Certainly, set up policy selection local breakout, promptly select vPDN-GW if the acquiescence that draws connects, and the situation of SAE CAMEL-Subscription-Information support local breakout, then can select vPDN-GW.
Do not support local breakout with the access zone network at UE place below and connected by acquiescence to set up strategy and learn when also not supporting local breakout, MME selects the hPDN-GW of ownership place to set up default bearing to describe.
S617:S-GW initiates default bearing to hPDN-GW and sets up request.
