Abstract

The invention discloses a method, system and equipment for informing and outputting selected IP (Internet Protocol) data shunt SIPTO (Selected IP Traffic Offload) activation and relates to the field of wireless communication for solving the problem that a user cannot acquire the SIPTO activation operation of the network. In the invention, after the network executes the SIPTO activation operation in a session management process, the SIPTO activation operation is informed to a user terminal to ensure that the user can acquire the SIPTO activation operation of the network.

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 are together referred to as H (e) NB.Current preliminary specifications points out that whether terminal (UE) has used the SIPTO technology to network is ignorant.

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

Some Internet business, when UE does not transmit data, these business just automatically finish, as UE by browser (Web Browser) while carrying out downloading web pages, after having downloaded webpage, just automatically finish both page download business between UE and server (Web Server).When there is no transfer of data, when the IP address of UE changes, UE just can directly be used new IP address to carry out the page download of back, without specifically, and extra operation.

But some Internet business, when UE does not transmit data, the business of these activation can not finish automatically, go back compartment of terrain between UE and these service servers (Server) and transmit some status datas (being similar to the mechanism of heartbeat), mainly some data that the Server of business has recorded UE, as its IP address, the service identification of UE, and the IP address of UE and the service identification of UE are 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 there is no data interaction between UE and Server, when as long as the IP address of UE changes, the business between UE and Server has just been interrupted (between UE and business, can not carry out the mutual of data), the user must again input the user name password by new IP address and be registered, when being registered on service server, UE could be used follow-up business.

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

The first, establishment stage activates SIPTO:

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

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

The second, activate SIPTO in the mobility management process under idle condition:

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

Characteristics of this method are only to allow at UE during in idle condition, just can carry out the activation manipulation of SIPTO, and now UE does not have the transmission of data, like this, the change of the IP address caused because of the activation of SIPTO, do not affect 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:

That two kinds of top Combination of Methods are used, set up in the first scheme when PDN connects and activate SIPTO simultaneously, when UE is positioned at idle condition and moves, new MME or new GW trigger PDN connection or the Bearer that will set up before this and carry out the SIPTO activation, the PDN soon set up before this connects or Bearer re-establishes a new PGW or GGSN, and the location comparison at the PGW that this is new or GGSN and the current place of UE is near.

Wherein scheme 1 is independently with scheme 2.Namely, after 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 scheme 2 in mobile process in early days.

For the activation of the establishment stage in such scheme 1 SIPTO, if activate SIPTO in PDN connection foundation or a Bearer foundation, 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, likely these crucial transfer of data or crucial application are interrupted.

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

Again for example, if the user makes a phone call by the Skype on UE and friend, when the user moves, UE was interrupted with being connected of network, and the user need to be made a phone call again with friend, and the user uses impression very bad.

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

PDN setting up between user and core-network side is connected or after Bearer carries out the SIPTO activation manipulation, the user is to SIPTO activation manipulation ignorant, if position has occurred the user, move, 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 is mainly to solve at PDN to connect and set up or Bearer while activating SIPTO while setting up, and owing to not notifying UE to cause UE in follow-up business use procedure, the problem of service disconnection may occur.But when the method that this patent proposes equally also is applicable in the mobility management process under idle condition activate SIPTO, notice UE.

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

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

Embodiment mono-:

Based on this patent method, propose, when UE initiates to set up a PDN from the E-UTRAN system, connect, 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 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 are two kinds of modes to set up a PDN and connect, one is that UE sets up a PDN connection in adhering to (Attach) process; In another process, after UE is registered to network, UE, by initiating a PDN connection request, connects thereby set up a PDN.And the activation of SIPTO be mainly select one with UE very near PDN GW on physics or geographical position.Possible method is that the ECGI by the tracking area identification at UE place (TAI) or UE place selects this PDN GW.

Although two kinds of PDN establishment of connection modes (is by the Attach process, and another is to connect process of establishing by PDN) are arranged, and two kinds of modes are closely similar on the NAS flow process.As shown in Figure 4 A, following flow process all can be applied the mode of setting up of these two kinds of PDN.

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

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

MME carries out the selection of PDN GW, selects one from UE physically or the PDNGW of address close to very.Then, MME sends establishment session request (Create Session Request) message and, to gateway (Serving GW), carries 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 (PDN Address), default EPS bearing service quality (Default EPS Bearer QoS), PDN type (PD NType), signing Access Point Name AMBR (subscribed APN-AMBR), Access Point Name (APN), EPS bearing identification (EPS Bearer Id), protocol configuration option (Protocol Configuration Options), switching indication (Handover Indication), ME identifies (ME Identity), customer position information (User Location Information (ECGI)), information of mobile user change report support indication (MS Info Change Reporting support indication), preference pattern (Selection Mode), charging feature (Charging Characteristics), track reference (Trace Reference), follow the tracks of type (Trace Type), 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 Bearer Flag).

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

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

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

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

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

Step 7:eNodeB/HENB sends wireless resource control connection reconfiguration (RRC Connection Reconfiguration) (wherein message comprises parameter EPS radio bearer sign (EPS Radio Bearer Identity)) message to 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 completes (RRC Connection Reconfiguration Complete) message to eNodeB/HENB.

Step 9:eNodeB/HENB sends S1 access point response (S1-AP Response) message to 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 and controls direct transmission (RRC Direct Transfer) message to eNodeB/HENB, this message comprises activation default EPS bearing context and accepts (ActiVate Default EPS Bearer Context Aceept) message, carry EPS Bearer Identity in this message, the information such as Protocol Configuration Options.ENodeB/HENB in up link Non-Access Stratum transmission (Uplink NAS Transport) message forward Activate Default EPS Bearer Context Accept message to MME.

It should be noted that, for the method for describing, the above only provides the committed step relevant to this patent, and the irrelevant step of some and this patent is not listed, and these steps do not provide, and do not affect the use of this patent.

Embodiment bis-:

Based on this patent method, propose, when UE initiates to set up a PDN connection from UTRAN or GERAN system, SGSN increases the sign SIPTO Activation Flag that a SIPTO activates in sending to the NAS message Activate PDP Context Request of UE.When this SIPTO Activation Flag is comprised in message or SIPTO Activation Flag gets a particular value and is activated with regard to showing the SIPTO that this PDN connects.As shown in Figure 4 B.

Step 1:UE initiates a PDN and connects, 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, Protocol Configuration Options, the information such as Request Type.

The APN that step 2:SGSN provides in step 1 according to UE or Request Type, and the subscription data of UE, and the Policy of the configuration in SGSN determines this PDN is connected to the activation of carrying out 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 PDN GW or the GGSN of address close to very.

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

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

Step 3: if that the SGSN selection is PDN GW, PDN GW returns and creates conversational response (Create Session Response) message to Serving GW, carry PDN GW Address for the user plane in this message, PDN GW TEID of the user plane, PDN GW TEID of the control plane, PDN Type, PDN Address, EPS Bearer Id, EPS Bearer QoS, Protocol Configuration Options, Charging Id, Prohibit Payload Compression, APN Restriction, Cause, MS Info Change Reporting Action (Start) (if the PDN GW decides to receive UE ' s location information during the session), the information such as APN-AMBR.Serving GW returns and creates conversational response (Create Session Response) message to SGSN, carry PDN Type in this message, PDN Address, Serving GW address for User Plane, Serving GW TEID for User Plane, Serving GW TEID for control plane, EPS Bearer Id, EPS Bearer QoS, Protocol Configuration Options, Charging Id, Prohibit Payload Compression, APN Restriction, Cause, MS Info Change Reporting Action (Start), the information such as APN-AMBR.

If that SGSN selects is GGSN, GGSN sends and creates block data protocol context response (Create PDP Context Response) message to SGSN, carry TEID in this message, PDP Type, PDP Address, Protocol Configuration Options, QoS Negotiated, Negotiated Evolved ARP, Charging Id, Prohibit Payload Compression, APN Restriction, Cause, MS Info Change Reporting Action, BCM) information such as message to the SGSN.

RAB between step 4:UE and RAN and SGSN is established.

Step 5:SGSN sends and activates block data protocol context response (Activate PDP Context Response) message to RNC/BSS/HNB, this message is carried PDP Type, PDP Address, TI, QoS Negotiated, Radio Priority, Packet Flow Id, Protocol Configuration Options, the information such as SIPTO Activation Flag.SIPTO Activation Flag is the sign that the indication SIPTO of this patent proposition is activated.The method that two kinds of indications are arranged, if a kind of indication is to include SIPTO Activation Flag parameter in Activate PDP Context Response message, the SIPTO that indicates this corresponding PDN to connect is activated, do not include SIPTO Activation Flag parameter in this message, the SIPTO that 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) means that the SIPTO that this corresponding PDN connects is activated, get another value (as 0) when SIPTO Activation Flag parameter, the SIPTO that indicates this corresponding PDN to connect is not activated.

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

Embodiment tri-:

Based on this patent method, propose, when UE is positioned at the E-UTRAN system, while setting up or revising an EPSBearer, MME increases 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 message or SIPTO Activation Flag gets a particular value and is activated with regard to the SIPTO that shows this EPS Bearer.

In the EPS system, having two kinds of modes to set up an EPS Bearer connects, one is that UE distributes request (Bearer Resource Allocation Request) or bearing resource modification request (Bearer Resource Modification Request) message to trigger by sending bearing resource, MME sends and activates special-purpose EPS bearer context request (Activate Dedicated EPS Bearer Context Request) to UE, and another kind is directly by network-triggered MME, to UE, to send Activate Dedicated EPS Bearer Context Request.No matter be which kind of method, whether MME increases a SIPTO Activation Flag parameter in send Activate Dedicated EPS Bearer Context Request to UE, just can indicate the SIPTO of this Bearer of UE to activate.

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

Embodiment tetra-:

Based on this patent method two, propose, when UE is positioned at the UTRAN/GERAN system, while setting up or revising a PDP Context, SGSN increases 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 message or SIPTO Activation Flag gets a particular value and is activated with regard to the SIPTO that shows this EPS Bearer.

When setting up a PDP Context, SGSN accepts (Activate PDP Context Accept) or activates second block data protocol context to increase the sign SIPTO Activation Flag that a SIPTO activates in accepting the message of (Activate Secondary PDP Context Accept) at the activation block data protocol context that sends to UE.When this SIPTO Activation Flag is comprised in message or SIPTO Activation Flag gets a particular value and is activated with regard to the SIPTO that shows this PDP Context.

When revising a PDP Context, SGSN increases the sign SIPTO Activation Flag that a SIPTO activates in sending to the modification packet data protocol context request of UE (Modify PDP Context Request) (modification of this PDP Context is initiated by SGSN) or revising block data protocol context acceptance (Modify PDP context Accept) (modification of this PDP Context is initiated by UE) message.When this SIPTO Activation Flag is comprised in message or SIPTO Activation Flag gets a particular value and is activated with regard to the SIPTO that shows this PDP Context.

Patented method three: when UE sets up a PDN connection, when the SIPTO that network indicates this PDN to connect is activated, the information that UE need to activate this SIPTO be presented to the user.

The method presented has a variety of, as shown a specifically indication on the screen of mobile phone; For data card, may need specific software to indicate to the user.

In addition, also have a kind of rendering method to be, as UE, when this PDN connects a business of initiation, point out this PDN to connect and be that SIPTO activates, allow the user whether continue to connect to carry this business with this PDN.If the user selects, continue to connect to carry this business with this PDN, otherwise, allow the user select other PDN to connect to carry this business.

Patented method four: when setting up or revising an EPS Bearer or PDP Context, when network indicates the SIPTO of this EPS Bearer or PDP Context to activate, the information that UE need to activate this SIPTO is presented to the user.

Rendering method is similar, and as top method, the method presented has a variety of, as shown a specifically indication on the screen of mobile phone; For data card, may need specific software to indicate to the user.

In addition, also have a kind of rendering method to be, as UE, when this EPS Bearer or PDP Context initiate a business, whether pointing out this PEPS Bearer or PDP Context is that SIPTO activates, allow the user continue to carry this business with this EPS Bearer or PDP Context.If the user selects, continue to carry this business with this EPS Bearer or PDP Context, otherwise, allow the user select other EPS Bearer or PDP Context to carry this business.

The method that this patent proposes is that network passes through NAS message, its SIPTO of indicating user terminal is activated, network also can be by S1 and RRC interface message in addition, or its corresponding PDN of Iu interface message and RRC interfac message notification user terminal connects or the SIPTO of Bearer is activated.In this case, this patent proposes SIPTO Activation Flag can be by S1 and RRC interface message, or Iu and RRC interfac message notification are to UE, but this need to revise the message of two interfaces simultaneously, therefore process is comparatively complicated, but basic skills is the same, just no longer provide specific description here.
