Description

Notice and output intent, system and equipment that selectivity IP data distribution activates

Technical field

The present invention relates to wireless communication field, relate in particular to notice and output intent, system and equipment that a kind of selectivity IP data distribution activates.

Background technology

Selectivity IP data distribution (Selected IP Traffic Offload, SIPTO) be that a kind of permission user data directly enters internet (Ineternet) or specific IP network (as company's network) by macro base station, and the technology that other data are still transmitted by core net, as shown in Figure 1.SIPTO can be applied to Home eNodeB, also can be applied to macro base station.The Home eNodeB here refers to Home NodeB or Home eNodeB, and they abbreviate H (e) NB together as.Present preliminary specifications points out that whether terminal (UE) has used the SIPTO technology to network is ignorant.

Because Long Term Evolution (LTE) system can support the access rate up to 100Mbps, when a lot of users was linked into core net use IP operation by the LTE system, the bandwidth of core net needed a lot.After using the SIPTO technology, therefore the data of user capture Ineternet or specific IP network will reduce the resource of the user plane of core net and use without core net.Like this, can reduce the cost of investment of the equipment and the network of Virtual network operator.

Some Internet business, when UE did not transmit data, these are professional just automatically to finish, as UE by browser (Web Browser) when downloading webpage, after having downloaded webpage, just automatically finish both page download business between UE and the server (WebServer).When not having transfer of data, when the IP address of UE changed, UE just can directly use new IP address to carry out the page download of back, need not specific, extra operation.

But some Internet business, when UE does not transmit data, the business of these activation can not finish automatically, go back the compartment of terrain between UE and these service servers (Server) and transmit some status datas (being similar to the mechanism of heartbeat), mainly be some data that professional Server has write down UE, as its IP address, the service identification of UE, and the IP address of UE and the service identification of UE bound.For example, QQ, Messenger, Skype etc. need the user to input user name, the business of password, and its server is bound user's IP address and user's sign.Even do not have data interaction between UE and the Server, when as long as the IP address of UE changes, then the business between UE and the Server has just been interrupted (can not carry out the mutual of data between UE and the business), the user must input the user name password once more by new IP address and register, when being registered on the service server, UE could use follow-up business.

When SA2 discusses the technical scheme of SIPTO, following three kinds of schemes are arranged at present:

First kind, establishment stage activates SIPTO:

When a Packet Data Network (PDN) connects when setting up, or a carrying (Bearer) activates SIPTO when setting up simultaneously, and the user can not perceive SIPTO and be activated;

When the user moved, when moving to new Mobility Management Entity (MME) as the user, the PDN connection or the Bearer that set up for SIPTO might be released.Like this, the business of transmitting on connection of the PDN on this SIPTO or Bearer just is interrupted.

Second kind, activate SIPTO in the mobility management process under the idle condition:

When PDN connect to set up or Bearer when setting up, and do not require whether activated SIPTO, but when the user is in idle condition, when UE moves, new MME or new gateway (GW) (or Gateway GPRS Support Node (GGSN)) trigger the PDN connection or the Bearer that will set up before this and carry out the SIPTO activation, the PDN that has soon set up before this connects or Bearer rebulids a new packet data gateway (PGW) or GGSN, and the position at PGW that this is new or GGSN and the current place of UE is closer.

Characteristics of this method are only to allow when UE is in idle condition, just can carry out the activation manipulation of SIPTO, and this moment, UE did not have the transmission of data, like this, the change of the IP address that causes because of the activation of SIPTO, do not influence the operation (as page download) of much follow-up business, but still be interrupted for the said business of registration that needs in front.

The third: the combination of SIPTO activates:

Be that two kinds of top methods are used in combination, promptly in first kind of scheme, set up and activate SIPTO when PDN connects simultaneously, when UE is positioned at idle condition and when mobile, new MME or new GW trigger the PDN connection or the Bearer that will set up before this and carry out the SIPTO activation, the PDN that has soon set up before this connects or Bearer rebulids a new PGW or GGSN, and the position at PGW that this is new or GGSN and the current place of UE is closer.

Wherein scheme 1 is independently with scheme 2.Just after the operational version 1, operational version 2.Operational version 1 not during operational version 2.Scheme 3 is that scheme 1 and scheme 2 are combined, and has scheme 1 and just can activate the characteristics that activate SIPTO in SIPTO and the scheme 2 in the process that moves in early days.

Activate SIPTO for the establishment stage in the such scheme 1, as if activating SIPTO in PDN connection foundation or when a Bearer sets up, the user may be transmitted some crucial data on this PDN connection or Bearer, or carries out the application of some keys.When the user moves, then might these crucial transfer of data or crucial application be interrupted.

For example, some website provides the software of its exploitation of user's download, but before download, the website needs the user to register some individual information, just allows then to download, when the user's download process, moved the position, its download is interrupted, and downloads this software once more, then might also top process to be repeated once, or after requiring to input user name and password once more, just allow its download, in a word, this operation is very complicated, and user's use experience is very bad.

Again for example, if the user makes a phone call by Skype on the UE and friend, when the user moved, UE was interrupted with being connected of network, and the user need make a phone call once more with friend, and user's use experience is very bad.

In using process of the present invention, the inventor finds to exist in the prior art following technical problem:

To being connected at the PDN that sets up between user and core-network side or after Bearer carries out the SIPTO activation manipulation, the user is to SIPTO activation manipulation ignorant, if the position has taken place and has moved in the user, then the business of the terminal of carrying on this PDN connection or Bearer may be interrupted, user's experience descends greatly, and network service quality also is affected.

Below the present invention is specifically described:

This patent mainly is to solve to connect at PDN to set up or Bearer when activating SIPTO when setting up, owing to do not notify UE to cause UE in follow-up professional use, the problem of service disconnection may occur.But the method that this patent proposes equally also is applicable to when activating SIPTO in the mobility management process under the idle condition, notice UE.

The main thought of this patent is to provide indication to UE when SIPTO activates.

Patented method one: when UE set up a PDN connection, when network activation SIPTO, the SIPTO that network need indicate this PDN of UE to connect was activated.

Embodiment one:

Propose based on this patent method, connect when UE initiates to set up a PDN from the E-UTRAN system, MME increases the sign SIPTO Activation Flag that a SIPTO activates in sending to the NAS message Activate Default EPS Bearer Context Request of UE.When this SIPTO Activation Flag is comprised in the message or SIPTO Activation Flag gets a particular value and is activated with regard to showing the SIPTO that this PDN connects.

In the EPS system, there is dual mode to set up a PDN and connects, one is that UE sets up a PDN connection in adhering to (Attach) process; After UE was registered to network, UE connected thereby set up a PDN by initiating a PDN connection request in another process.And the activation of SIPTO mainly be select one with UE very near PDN GW on physics or geographical position.Possible method is that the ECGI by tracking area identification at UE place (TAI) or UE place selects this PDN GW.

Though two kinds of PDN establishment of connection modes (is by the Attach process, and another is to connect the process of setting up by PDN) are arranged, and dual mode is closely similar on the NAS flow process.Shown in Fig. 4 A, following flow process all can be used the mode of setting up of these two kinds of PDN.

Step 1:UE initiates a PDN and connects, then UE sends PDN connection request (PDNConnectivity Request) message and gives eNodeB or HeNB, carries Access Point Name (APN), PDN type (PDN Type), protocol configuration option (Protocol Configuration Options), request type information such as (Request Type) in this message.

APN or Request Type that step 2:MME provides in step 1 according to UE, and the subscription data of UE, and the decision of the configured strategy (Policy) among the MME is to this PDN connection carrying out activation of SIPTO.

MME carries out the selection of PDN GW, selects one from UE physically or the very near PDNGW in address.Then, MME sends and creates conversation request (Create Session Request) message to gateway (Serving GW), carry international mobile subscriber identification code (IMSI) in this message, 2G/3G phone number (MSISDN), the MME Tunnel End Point Identifier of chain of command (MME TEID for control plane), wireless access type (RAT type), PDN Gateway address (PDN GW address), PDN address (PDNAddress), default EPS bearing service quality (Default EPS Bearer QoS), PDN type (PDNType), signatory Access Point Name AMBR (subscribed APN-AMBR), Access Point Name (APN), EPS bearing identification (EPS Bearer Id), protocol configuration option (Protocol Configuration Options), switch indication (Handover Indication), ME identifies (ME Identity), customer position information (UserLocation Information (ECGI)), information of mobile user change report support indication (MS InfoChange Reporting support indication), preference pattern (Selection Mode), charging feature (Charging Characteristics), track reference (Trace Reference), follow the tracks of type (TraceType), trigger sign (Trigger Id), operation maintenance center's sign (OMC Identity), maximum APN zone (Maximum APN Restriction), dual address carrying sign information such as (Dual Address BearerFlag).

Step 3:Serving GW sends Create Session Request message to PDN GW, carries IMSI in this message, MSISDN, Serving GW Address for the user plane, Serving GW TEIDof the user plane, Serving GW TEID of the control plane, RAT type, Default EPSBearer QoS, PDN Type, PDN Address, subscribed APN-AMBR, APN, Bearer Id, Protocol Configuration Options, Handover Indication, ME Identity, User LocationInformation (ECGI), MS Info Change Reporting support indication, SelectionMode, Charging Characteristics, Trace Reference, Trace Type, Trigger Id, OMCIdentity, Maximum APN Restriction, information such as Dual Address Bearer Flag.

Step 4:PDN GW returns and creates conversational response (Create Session Response) message to Serving GW, the PDN GW address (PDN GW Address for theuser plane) of carrying user's face in this message, the PDN GW Tunnel End Point Identifier of user's face (PDN GW TEID of the userplane), the PDN GW Tunnel End Point Identifier of chain of command (PDN GW TEID of the control plane), PDN type (PDN Type), PDN address (PDN Address), EPS bearing identification (EPS BearerId), EPS bearer quality of service (EPS Bearer QoS), protocol configuration option (ProtocolConfiguration Options), charging identifier (Charging Id), forbid load compression (Prohibit PayloadCompression), APN retrains (APN Restriction), reason (Cause), information of mobile user change report action (MS Info Change Reporting Action), Access Point Name AMBR information such as (APN-AMBR).

Step 5:Serving GW returns Create Session Response message and gives MME, carry PDN Type in this message, PDN Address, Serving GW address for User Plane, Serving GWTEID for User Plane, Serving GW TEID for control plane, EPS Bearer Id, EPSBearer QoS, Protocol Configuration Options, Charging Id, Prohibit PayloadCompression, APN Restriction, Cause, MS Info Change Reporting Action (Start), information such as APN-AMBR.

Step 6:MME sends and activates default EPS bearing context request (Activate Default EPSBearer Context Request) message to eNodeB/HENB, carry APN in this message, PDN Type, PDN Address, EPS Bearer Id, Protocol Configuration Options, SIPTO activation marker information such as (SIPTO Activation Flag).

This message is included in the S1_MME control message, the RAB that is evolution is set up in request (e-RAB Setup Request) or initial context foundation request (Initial Context SetupRequest) message, these two message all comprise EPS Bearer Identity, EPS Bearer QoS, UE-AMBR, gateway up link IP address (Serving GW UL IP address), S1 Tunnel End Point Identifier parameters such as (S1-TEID).Wherein, when the PDN connection procedure that UE initiates, then S1_MMEControl message is e-RAB Setup message, connects if UE is the PDN that sets up in the Attach process, and then S1_MME Control message is Initial Context Setup Request message.SIPTO ActivationFlag is the sign that the indication SIPTO of this patent proposition is activated.The method that two kinds of indications are arranged, a kind of indication is if include SIPTOActivation Flag parameter in the Activate Default EPS Bearer Context Request message, the SIPTO that then indicates this corresponding PDN to connect is activated, do not include SIPTO Activation Flag parameter in this message, the SIPTO that then indicates this corresponding PDN to connect is activated.And another kind of indicating means to be SIPTO Activation Flag get that a value (as 1) represents that the SIPTO that this corresponding PDN connects is activated, get another value (as 0) when SIPTO Activation Flag parameter, the SIPTO that then indicates this corresponding PDN to connect is not activated.

Step 7:eNodeB/HENB sends wireless resource control connection reconfiguration (RRC ConnectionReconfiguration) (wherein message comprises parameter EPS radio bearer sign (EPS Radio BearerIdentity)) message and gives UE, and Activate Default EPS Bearer Context Request message is comprised in this RRC message and is transmitted to UE.

Step 8:UE sends wireless resource control connection reconfiguration and finishes (RRC ConnectionReconfiguration Complete) message to eNodeB/HENB.

Step 9:eNodeB/HENB sends S1 access point response (S1-AP Response) message and gives MME.This S1-AP Response message comprises S1-U interface downstream IP address and the TEID that eNodeB/HENB distributes.

Step 10:UE sends Radio Resource control and directly transmits (RRC Direct Transfer) message to eNodeB/HENB, this message comprises activation default EPS bearing context and accepts (Activate DefaultEPS Bearer Context Aceept) message, carry EPS Bearer Identity in this message, information such as ProtocolConfiguration Options.The eNodeB/HENB preceding Activate of commentaries on classics Default EPS Bearer Context Accept message in up link Non-Access Stratum transmission (UplinkNAS Transport) message is given MME.

Need to prove, for the method for describing, only provide the committed step relevant with this patent above, the step that some and this patent have nothing to do is not listed, and these steps do not provide, and do not influence the use of this patent.

Embodiment two:

Propose based on this patent method, connect when UE initiates to set up a PDN from UTRAN or GERAN system, SGSN increases the sign SIPTO Activation Flag of a SIPTO activation in sending to the NAS message Activate PDP Context Request of UE.When this SIPTO Activation Flag is comprised in the message or SIPTO Activation Flag gets a particular value and is activated with regard to showing the SIPTO that this PDN connects.Shown in Fig. 4 B.

Step 1:UE initiates a PDN and connects, then UE sends and activates packet data protocol context request (Activate PDP Context Request) message to RNC/BSS/HNB, carry NSAPI in this message, TI, PDP Type, PDP Address, Access Point Name, QoS Requested, ProtocolConfiguration Options, information such as Request Type.

APN or Request Type that step 2:SGSN provides in step 1 according to UE, and the subscription data of UE, and the Policy of the configuration among SGSN decision is to this PDN connection carrying out activation of SIPTO.

SGSN carries out the selection of gateway, and the gateway of selection also comprises the selection of PDN GW or GGSN, and selects one from UE physically or very near PDN GW or the GGSN in address.

If that SGSN selects is PDN GW, then SGSN sends and creates conversation request (Create SessionRequest) message to Serving GW, carry IMSI in this message, MSISDN, SGSN TEID forcontrol plane, RAT type, PDN GW address, PDN Address, Default EPS Bearer QoS, PDN Type, subscribed APN-AMBR, APN, EPS Bearer Id, Protocol ConfigurationOptions, Handover Indication, ME Identity, User Location Information (ECGI), MSInfo Change Reporting support indication, Selection Mode, ChargingCharacteristics, Trace Reference, Trace Type, Trigger Id, OMC Identity, MaximumAPN Restriction, information such as Dual Address Bearer Flag; Serving GW sends CreateDefault Bearer Request message to PDN GW, carry IMSI in this message, MSISDN, ServingGW Address for the user plane, Serving GW TEID of the user plane, Serving GWTEID of the control plane, RAT type, Default EPS Bearer QoS, PDN Type, PDNAddress, subscribed APN-AMBR, APN, Bearer Id, Protocol Configuration Options, Handover Indication, ME Identity, User Location Information (ECGI), MS InfoChange Reporting support indication, Selection Mode, Charging Characteristics, Trace Reference, Trace Type, Trigger Id, OMC Identity, Maximum APN Restriction, information such as Dual Address Bearer Flag.

If that SGSN selects is GGSN, then SGSN sends and creates packet data protocol context request (Create PDP Context Request) message to GGSN, carry PDP Type in this message, PDPAddress, Access Point Name, QoS Negotiated, Negotiated Evolved ARP, TEID, NSAPI, MSISDN, Selection Mode, Charging Characteristics, Trace Reference, Trace Type, Trigger Id, OMC Identity, Protocol Configuration Options, servingnetwork identity, Maximum APN Restriction IMEISV, CGI/SAI, User CSGInformation, RAT type, S-CDR CAMEL information, MS Info Change Reportingsupport indication, NRSN, information such as Dual Address Bearer Flag;

Patented method two: when setting up or revising an EPS Bearer or PDP Context, when network activation SIPTO, network need indicate the SIPTO of this EPS Bearer of UE or PDP Context to be activated.

Embodiment three:

Propose based on this patent method, when UE was positioned at the E-UTRAN system, when setting up or revising an EPSBearer, MME increased the sign SIPTO Activation Flag that a SIPTO activates in sending to the NAS message of UE.When this SIPTO Activation Flag is comprised in the message or SIPTOActivation Flag gets a particular value and is activated with regard to the SIPTO that shows this EPS Bearer.

In the EPS system, having dual mode to set up an EPS Bearer connects, one is that UE triggers by sending bearing resource request for allocation (Bearer Resource Allocation Request) or bearing resource modification request (Bearer Resource Modification Request) message, MME sends to UE and activates special-purpose EPS bearer context request (Activate Dedicated EPS Bearer Context Request), and another kind is directly to send Activate Dedicated EPS BearerContext Request by network-triggered MME to UE.No matter be which kind of method, whether MME just can indicate the SIPTO of this Bearer of UE to activate send SIPTO Activation Flag parameter of increase among the Activate Dedicated EPSBearer Context Request to UE.

In addition, MME can also send modification EPS bearer context request (Modify EPSBearer Context Request) message to UE and revise service quality (QoS) or the TFT parameter of an EPS Bearer, equally, whether this patent proposes MME send SIPTO Activation Flag parameter of increase among the Modify EPS Bearer Context Request to UE, just can indicate the SIPTO of this EPS Bearer that is modified of UE to activate.

Embodiment four:
