Abstract

The invention discloses a method and equipment for ensuring IP (Internet Protocol) continuity, and aims to solve the problem that the IP continuity cannot be ensured since IP streams transmitted through PDN (Packet Data Network) connection established before reestablishment are all interrupted during execution of SIPTO (Selected IP Traffic Offload) under an existing mechanism. The method comprises the following steps that: a terminal determines a PDN connection which does not require the initiation of a deactivation process carrying a reactivation request during execution of an SIPTO function with network side equipment; and the terminal informs the network side equipment of the determined PDN connection in order that the network side equipment does not initiate the deactivation process carrying the reactivation request for the PDN connection which is relevant with an APN (Access Point Name) and does not require the initiation of the deactivation process carrying the reactivation request during execution of the SIPTO function when the network side equipment executes the SIPTO. Thus, the transmission of long-lifecycle IP streams/real-time IP streams is ensured, and the service experience of a user is improved.

Description

The successional method and apparatus of a kind of guarantee IP
Technical field
The present invention relates to wireless communication technology field, particularly one ensures Internet Protocol (Internet Protocol, IP) successional method and apparatus.
Background technology
The unloading of selectivity Internet Protocol flow (Selected IP Traffic Offload, SIPTO; Internet Protocol, IP) function refers to, the flow of particular type is unloaded to geographical position or topology location from the nearer network node of the attachment point of subscriber equipment (User Equipment, UE) by operator.According to user's surface current amount of UE the need of the core network through operator, SIPTO is divided into SIPTO(Radio Access Network, RAN on SIPTO above RAN(Radio Access Network)) and the SIPTO of SIPTO at the Local Network(local network).
1、SIPTO above RAN；
SIPTO above RAN refers to and selects the networking close to the attachment point of UE on geographical position or topology location to close (gateway (Serving Gateway, S-GW) and packet data network gateway (PDN Gateway, P-GW; Packet Data Network, PDN)).Therefore, in SIPTO above RAN, user's surface current amount of UE needs the P-GW shunting by being positioned at mobile operator core net.
Flow unloading is only to universal mobile telecommunications system land radio access web (UMTS Terrestrial Radio Access Network, UTRAN; Universal Mobile Telecommunications System, UMTS) and evolved universal mobile communication system land radio access web (Evolved-UTRAN, E-UTRAN) access is effectively.When UE enters into UTRAN/E-UTRAN from the access network of other types, new service universal grouping wireless business supporting node (Serving GPRS Support Node, SGSN; General Packet Radio Service, GPRS)/Mobility Management Entity MME(Mobility Management Entity), according to APN (Access Point Name, APN) SIPTO license (being configured with this information in SGSN/MME), determine to connect the need of execution deexcitation for specific PDN, the operation then reactivated.
Because UE moves, target MME/SGSN finds to change the position of UE, and (such as MME is at tracing section updating (Tracking Area Update, TAU) find in process, or SGSN is at Routing Area Update (Routing Area Update, RAU) process finds), or UE is from global system for mobile communications/GSM evolution enhanced data rates for GSM evolution wireless access network (GSM/EDGE Radio Access Network, GERAN; Global System for Mobile communication, GSM; Enhanced Data Rates for GSM Evolution, EDGE) UTRAN/E-UTRAN is entered, connect because UE establishes the PDN relevant to having APN that SIPTO permits, this part PDN connection is redirected to the nearer PDN GW of distance UE, to realize the optimization of data routing paths according to the determining positions of UE by target MME/SGSN.The above-mentioned PDN of target MME/SGSN deexcitation connects, and in the process of deexcitation, indicate UE to reactivate PDN connection (namely MME/SGSN initiates to carry the deactivation process of the request of reactivating).After UE executes the deactivation process of above-mentioned PDN connection, UE initiates the activation of PDN connection according to above-mentioned instruction, and target MME/SGSN is by PDN GW nearer for the attachment point for this PDN connection selection distance UE in this process.
2、SIPTO at the Local Network；
SIPTO at the Local Network function supports that UE is directly connected to an IP network (such as Internet) by (H) eNB, and the user face of UE does not need the network passing through mobile operator.Subscription data in home subscriber server (Home Subscriber Server, HSS) shows whether allow at local network relieving flowing volume based on the every APN of every user to MME.
The implementation of SIPTO at the Local Network is: select to close the local gateway (Local – Gateway, L-GW) established or the independent gateway (wherein S-GW and L-GW is located at consolidated network entity) selecting to be positioned at local network with (H) eNB.IP flow selected under these two kinds of scenes is all unloaded by local network.
Current L-GW and there is not interface between policy control and charging rule functions (Policy Control and Charging Rules Function, PCRF), so can use the PDN of SIPTO at the Local Network to connect do not support dedicated bearer.L-GW should refuse any bearing resource amendment request that UE sends.
If MME finds that the SIPTO license in the subscription data of the specific APN of a specific contracted user changes, and the SIPTO at the Local Network PDN that this user has established APN specific for this relevant connects, MME should discharge the SIPTO at the Local Network PDN relevant to this APN and connect, and carries the request of reactivating (reactivation requested) in PDN disconnection request message.
In sum, when performing at present SIPTO, the first deexcitation PDN that set up relevant to having APN that SIPTO permits is needed to connect, and show that needing to re-establish this PDN connects to UE, then, UE, after releasing this PDN and connecting, initiates the process of rebuilding this PDN connection.In the process of rebuilding PDN connection, network equipment (as MME) is by gateway GW(PGW or LGW nearer for position current for selection distance UE), with optimizing data path.Because the PDN after rebuilding connects different from the GW that the PDN set up before reconstruction connects, under current mechanism, when performing SIPTO, the IP stream connecting transmission via the PDN set up before reconstruction will all interrupt, thus IP continuity cannot be ensured, this operating process is flowed (short-lived flows) to short-life-cycle IP and (is namely required low IP stream to IP continuity, such as browsing page) impact less, but (long-lived flows)/Real-Time IP stream (real-time flows) is flowed to long life cycle IP and (namely high IP stream is required to IP continuity, such as voice call, file transfer protocol (FTP) (File Transport Protocol, FTP) download etc.) impact very large, also have impact on the service experience of user.

Under which, the method that the embodiment of the present invention provides also comprises: terminal stores the information that self determined network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function after replying message receive that network equipment returns first.
Preferably, can carrying for representing the information that the network equipment determined receiving terminal does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function in this first reply message, also can not carry any information.
In force, network equipment above-mentionedly directly returns except the first reply message confirms except adopting, can also after the first request message receiving terminal transmission, the PDN of the deactivation process initiating to carry the request of reactivating can not needed to connect when performing SIPTO function for the determined every bar network equipment of terminal yet, judge that this PDN connects whether relevant to having the APN that SIPTO permits, and first reply in message carry for represent network equipment that terminal is determined do not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function in the relevant information there is the incoherent PDN of APN that SIPTO permits being connected.
Accordingly, terminal is carried for after representing during network equipment that terminal determines does not need when performing SIPTO function the PDN of the deactivation process initiating to carry the request of reactivating to connect and replying message with first with the relevant information that the incoherent PDN of APN that SIPTO permits is connected receiving, except this first other PDN replied except PDN connection indicated in message connects the network equipment self determined does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function in, being defined as final network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function, and store final network equipment perform SIPTO function time do not need the PDN of the deactivation process initiating to carry the request of reactivating to connect information, otherwise, the information that the all-network side apparatus that terminal storage self is determined does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function.
Further, the method for the embodiment of the present invention also comprises:
After determined network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating connection to change when performing SIPTO function, the network equipment after terminal determines renewal does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function;
Terminal sends the second request message to network equipment, and the relevant information that the network equipment carry renewal in this second request message after does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function; And,
After terminal replys message receive that network equipment returns second, upgrade the information that the network equipment that self stores does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function.
Concrete, the transmission of the IP stream that if at least one network equipment that terminal is determined does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect has completed this particular type when performing SIPTO function, now, network equipment can initiate for this PDN connection the deactivation process carrying the request of reactivating when performing SIPTO function; Or, the network equipment determined except terminal during the PDN that this terminal has been set up connects does not need other PDN connection except the PDN of the deactivation process initiating to carry the request of reactivating connection to start to transmit the IP stream of particular type when performing SIPTO function, now, network equipment does not just connect for this PDN the deactivation process initiating to carry the request of reactivating when performing SIPTO function.Above-mentioned two situations are the determined network equipment of terminal does not need the PDN of the deactivation process initiating to carry the request of reactivating connection to change when performing SIPTO function, under this scene, terminal needs the network equipment after determining renewal not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function, and inform network equipment, the information that the network equipment self preserved of upgrading in time to make network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function.
In aforesaid way, after network equipment receives the second request message of terminal transmission, the second reply message returned directly to terminal confirms.
Preferably, this second replys in message the information can carried and not need the PDN of the deactivation process initiating to carry the request of reactivating to connect for the network equipment after representing the renewal that receiving terminal is determined when performing SIPTO function, also can not carry any information.

In order to save signaling consumption, as the further optimization to mode A, specifically comprise following two kinds of modes:
As the first optimal way, step 11 comprises: after terminal receives the first notification message of network equipment transmission, from self set up and during the PDN relevant to the APN carried this first notification message connect, determine that the PDN of the IP stream of current transmission particular type connects, wherein, carry the APN needing to perform SIPTO function in this first notification message, and the PDN determined is connected be defined as network equipment and do not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function.
In this first optimal way, the first notification message is used to indicate terminal does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect to the network equipment that network equipment transmission is relevant to APN indicated in this first notification message relevant information when performing SIPTO function.
In this first optimal way, accordingly, step 12 is specially: terminal sends the 3rd to network equipment and replys message, and replys in message the relevant information of carrying the network equipment self determined and not needing the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function the 3rd.
As the second optimal way, step 11 comprises: terminal is after the second notification message receiving network equipment transmission, from self set up and the PDN relevant to having APN that SIPTO permits connect, determine current transmission particular type IP stream PDN connect, and by the PDN determined connect be defined as network equipment perform SIPTO function time do not need the PDN of the deactivation process initiating to carry the request of reactivating to connect.
In this second optimal way, the second notification message is used to indicate the relevant information that terminal does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect to network equipment transmission network equipment when performing SIPTO function.
In this second optimal way, accordingly, step 12 is specially: terminal sends the 3rd to network equipment and replys message, and replys in message the relevant information of carrying the network equipment self determined and not needing the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function the 3rd.
Under above-mentioned two kinds of optimal way, terminal, after the first notification message receiving network equipment or the second notification message, determines that network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function.And the parameter information that can carry in the notification message that the relevant information that network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when notification terminal sends network equipment in execution SIPTO function to network equipment uses for representing the APN that the PDN needing to perform SIPTO process connects, also can not carry this parameter information, namely network equipment in used notification message for representing that the parameter information of the APN that the PDN needing to perform SIPTO process connects is optional.Concrete, if carry this parameter information to be the first notification message, if do not carry this parameter and information is the second notification message.
Above-mentioned the first involved request message and first replys message, the second request message and second replys message, the first notification message, the second notification message and the 3rd are replied message and be new signaling message.
The optimal way of which A and mode A is all applicable to the application scenarios of SIPTO above RAN and SIPTO at the Local Network.
If mode B terminal is current need the IP stream transmitting particular type, and needs to set up new PDN and connect and transmit, then:
Step 11 comprises: this new PDN connection is defined as network equipment by terminal does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function.
Accordingly, step 12 comprises: terminal sends PDN connection request (PDN connectivity request) message to network equipment, and carries in this PDN connection request message for representing that PDN that terminal institute asks to set up connects the indication information for network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when execution SIPTO function.

Below in conjunction with following embodiment, the reciprocal process in the successional method of guarantee IP provide the embodiment of the present invention between terminal and network equipment (for MME) is described in detail.
What embodiment one, the present embodiment described is by use new message to realize method that UE with MME safeguards the network equipment relevant to having APN that SIPTO permits does not need the PDN of the deactivation process initiating to carry the request of reactivating to be connected information when performing SIPTO function.
Suppose that APN1 has SIPTO license, UE establishes two PDN connections relevant to APN1, and namely PDN connects 1 and is connected 2 with PDN.User is current is performing voice call (i.e. Real-Time IP stream), FTP download (i.e. long life cycle IP stream) and web page browsing (namely short-life-cycle IP flows) application, wherein, the data of voice call connect 1 transmission by PDN, and FTP downloads and is connected 2 transmission with the data of web page browsing by PDN.
Reciprocal process in the present embodiment between UE and MME is shown in Figure 3, comprising:
Step 31, UE send SIPTO request message to MME, and the parameter of this SIPTO request message is PDN connection 1 is connected the default bearing of 2 mark with PDN.
After step 32, MME receive SIPTO request message, due to PDN connect 1 to be connected with PDN 2 all relevant to the APN that can perform SIPTO, so the request of UE is effective, MME connects 1 at PDN and to be connected with PDN in the context of 2 to store respectively and not to connect for this PDN the information that initiation carries the deactivation process of the request of reactivating for representing when performing SIPTO, then, MME returns SIPTO to UE and replys message.
After a period of time, the FTP down load application of user is finished, because PDN connects 2 transmission to the data of web page browsing application, therefore, it is no longer that network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function that PDN connects 2, UE determines that upgrading network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function, when performing SIPTO, 2 are connected for PDN, initiate the deactivation process carrying the request of reactivating, detailed process as shown in Figure 4, comprise:
Step 41, UE send SIPTO request message to MME, and the parameter of this SIPTO request message is the mark that PDN connects the default bearing of 1.
After step 42, MME receive SIPTO request message, upgrade the context self stored, and return SIPTO reply message to UE.
In this step, context that the every bar PDN relevant to having APN that SIPTO permits that MME searches that this UE set up connects (in the present embodiment for PDN connect 1 and PDN connect 2 context), because SIPTO request message only comprises the information that PDN connects 1, and MME finds that PDN connects in the context of 1 information having stored and do not initiated to carry the deactivation process of the request of reactivating for representing when performing SIPTO for this PDN connection, then MME does not revise the context that PDN connects 1; Due to the information not having PDN to connect 2 in SIPTO request message, but MME finds that the context of PDN connection 2 also stores the information not initiating to carry the deactivation process of the request of reactivating for representing when performing SIPTO for this PDN connection, but SIPTO request message does not comprise the information that PDN connects 2, so MME connects the context of 2 information of deleting and not initiating to carry the deactivation process of the request of reactivating for representing when performing SIPTO for this PDN connection from PDN.
What embodiment two, the present embodiment described is realizes by revising existing message the method that UE with MME safeguards the network equipment relevant to having APN that SIPTO permits does not need the PDN of the deactivation process initiating to carry the request of reactivating to be connected information when performing SIPTO function.
Suppose that APN1 has SIPTO license, UE does not also set up the PDN relevant to APN1 and connects.User performs web page browsing application, this operation triggers UE and sets up the PDN connection relevant to APN1, the IP formed due to the data of web page browsing application flows for short-life-cycle IP flows, and therefore during execution SIPTO, UE wishes that MME connects the deactivation process can initiating to carry the request of reactivating for this PDN.UE sends existing PDN connection request message to MME.
If user performs voice call application, because voice call is higher to qos requirement, the carrying of transmission web browsing data cannot meet the qos requirement of voice call, and UE determines that a newly-built dedicated bearer is used for the data of transferring voice talk application in above-mentioned PDN connects.In addition, the IP stream that the data due to voice call application are formed is Real-Time IP stream, and therefore UE wishes that MME does not connect for this PDN the deactivation process initiating to carry the request of reactivating when performing SIPTO function.When UE sends request bearing resource amendment message to MME, be carried in this request bearing resource amendment message when performing SIPTO function and do not ask PDN corresponding to dedicated bearer set up to connect the information that initiation carries the deactivation process of the request of reactivating for this terminal institute.Accordingly, after MME receives this message, in the context that corresponding PDN connects, store the indication information not initiating to carry the deactivation process of the request of reactivating for representing when performing SIPTO function for this PDN connection.
If user performs FTP down load application, UE determines the data transmitting this application with the carrying of having set up that the PDN relevant to APN1 set up connects, the IP stream formed due to the data of FTP download is long life cycle IP stream, and UE shows not need when performing SIPTO function to connect the deactivation process initiating to carry the request of reactivating, so UE can directly receive and dispatch the data relevant to FTP down load application for this PDN to MME;
Further, user does not perform voice call application after execution web page browsing, but directly perform FTP down load application, because FTP downloads not high to qos requirement, the data of the carrying transmission FTP down load application of the data that can directly use transmission network page browsing to apply, so do not need to set up new dedicated bearer.But the IP stream that the data that FTP downloads are formed is long life cycle IP stream, therefore do not need when performing SIPTO function to connect for this PDN the deactivation process initiating to carry the request of reactivating to show to MME, UE sends PDN connection request message to MME, the APN that the PDN that the data being transmission FTP down load application by the APN optimum configurations in this PDN connection request message use connects, the PDN type that the PDN that the data being set to by PDN type parameter in this PDN connection request message transmit FTP down load application use connects, and carry for represent terminal ask set up PDN connect for network equipment perform SIPTO function time do not need the PDN of the deactivation process initiating to carry the request of reactivating to connect indication information.
Accordingly, after MME receives this PDN connection request message, due to parameter entrained in message and the PDN that this UE has set up connect identical, and carry in this PDN connection request message for represent terminal ask set up PDN connect for network equipment perform SIPTO function time do not need the PDN of the deactivation process initiating to carry the request of reactivating to connect indication information, the object that the known UE of MME sends this PDN connection request message does not need when performing SIPTO function to connect for this PDN the deactivation process initiating to carry the request of reactivating to show, MME stores the indication information not initiating to carry the deactivation process of the request of reactivating for representing when performing SIPTO function for this PDN connection in the context that corresponding PDN connects.Then, MME returns PDN connection refused message directly to UE and confirms, and in this PDN connection refused message, carry the information for representing the indication information that receiving terminal is carried in PDN connection request message.
Embodiment three, the present embodiment, based on the process shown in Fig. 4, describe the process of the information and executing SIPTO that MME stores according to this locality.
When the position of UE changes, the PGW that the current location of MME detective distance UE is nearer, connect because UE establishes the PDN relevant to having APN1 that SIPTO permits, MME determines to perform SIPTO.The PDN connection 1 relevant to APN1 stored according to this locality and PDN connect the context of 2, MME known needs connects for PDN the deactivation process that 1 initiates to carry the request of reactivating, and connects 2 can initiate the deactivation process carrying the request of reactivating for PDN.Therefore, MME initiates to delete the process that PDN connects 2, and MME carries the information reactivating this PDN and connect in deexcitation carrying request (deactivate bearer request) message.
In embodiment four, the present embodiment, suppose that APN1 has SIPTO license, the PDN relevant to APN1 that UE has set up connects for PDN connects 1 and PDN connection 2.User is current is performing voice call and web page browsing application, and the data of wherein voice call connect 1 transmission by PDN, and the data of web page browsing connect 2 transmission by PDN.When UE is moved, MME find from UE position more close to PGW, due to APN1 have SIPTO license, so MME shows now can perform SIPTO to UE, detailed process as shown in Figure 5, comprising:
Step 51, MME send SIPTO notification message to UE, and the parameter of this SIPTO notification message is APN1;
The PDN relevant to APN1 that step 52, UE have set up connects and comprises PDN connection 1 and PDN connection 2, what wherein PDN connected 1 transmission is the data of voice call, the IP stream that these data are formed is Real-Time IP stream, so UE wishes that MME does not connect for this PDN the deactivation process that 1 initiates to carry the request of reactivating when performing SIPTO function.UE returns SIPTO to MME and replys message, and the parameter that this SIPTO replys message is the default bearing mark that PDN connects 1.
Accordingly, MME receives SIPTO and replys message, replys the parameter in message according to this SIPTO, and known UE wishes that MME does not connect for this PDN the deactivation process that 1 initiates to carry the request of reactivating when performing SIPTO function; MME connects in the context of 1 information storing and do not initiate to carry the deactivation process of the request of reactivating for representing when performing SIPTO function for this PDN connection at PDN.Therefore, MME can initiate for PDN connection 2 deactivation process (detailed process please refer to 3GPP TS23.401) carrying the request of reactivating.
Under embodiment five, the present embodiment describe SIPTO at the Local Network scene, UE with MME safeguards the method for the network equipment relevant to having APN that SIPTO permits does not need the PDN of the deactivation process initiating to carry the request of reactivating to be connected information when performing SIPTO function.
Suppose that APN1 has SIPTO license, the PDN relevant to APN1 that UE has set up connects for PDN connects 1 and PDN connection 2.User is current is performing voice call and web page browsing application, and the data of wherein voice call connect 1 transmission by PDN, and the data of web page browsing connect 2 transmission by PDN.When UE is moved, MME finds that the Local Home Network ID of UE changes (S-GW and L-GW closes and establish scene) or L-GW address changes (L-GW and (H) eNB closes and establishes scene), subscription data due to user shows to use SIPTO at the Local Network function to APN1, so MME shows now can perform SIPTO to UE, detailed process as shown in Figure 6, comprising:
Step 61, MME send SIPTO notification message to UE, and the parameter of this SIPTO notification message is APN1;
Step 62, UE are receiving SIPTO notification message, determine that network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function, and return SIPTO reply message to MME, the parameter that this SIPTO replys message is the information (as the default bearing mark that this PDN connects) that determined network equipment does not need the PDN of the deactivation process initiating to carry the request of reactivating to connect when performing SIPTO function, specific as follows:
UE finds that the PDN relevant to APN1 self set up connects and comprises PDN connection 1 and PDN connection 2, the data of voice call that what wherein PDN connected transmission on 1 is, and the IP stream that these data are formed is Real-Time IP stream, so UE wishes that MME does not connect 1 PDN initiating to carry the deactivation process of the request of reactivating for PDN when performing SIPTO function and connects, then the parameter that UE replys message to the SIPTO that MME returns is the default bearing mark that PDN connects 1.
Accordingly, MME receives SIPTO and replys message, replys the parameter of message according to this SIPTO, and known UE wishes that MME does not connect for this PDN the deactivation process that 1 initiates to carry the request of reactivating when performing SIPTO function; MME connects in the context of 1 information storing and do not initiate to carry the deactivation process of the request of reactivating for representing when performing SIPTO function for this PDN connection at PDN.Therefore, MME can initiate for PDN connection 2 deactivation process (detailed process please refer to 3GPP TS23.401) carrying the request of reactivating.
Said method handling process can realize with software program, and this software program can be stored in storage medium, when the software program stored is called, performs said method step.
