Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment of the invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
As shown in Figure 1, the embodiment of the invention provides a kind of method of updating service quality, comprising:
The first modification bearing request message that S10, receiving target network gateway send, the described first modification bearing request message is carried the objective network service quality after the objective network mobile management net element shines upon source network service quality; And
S20 is updated to described objective network service quality with the described source network service quality of formerly preserving, thereby transmits accordingly according to described objective network service quality.
When needing to switch to or position when being updated to the objective network mobile management net element in the switching of subscriber equipment at heterogeneous networks, carry out more new technological process of switching flow or position from the source network mobile management net element.At this moment, the first modification bearing request message that data gateway receiving target network gateway sends, this first revises bearing request message and is used for the notification data gateway and upgrades downlink tunnel information, and this first is revised bearing request message and carried the objective network service quality of objective network mobile management net element after with the source network service quality mapping.Data gateway receives first and revises after this objective network service quality that bearing request message carries, the source network service quality of formerly preserving is updated to this objective network service quality, and need not carry out service quality mapping, thereby data gateway can transmit accordingly according to this objective network service quality.Subsequently, data gateway can send the first modification bearing response message that the first modification bearing request message is responded to the objective network gateway, and notification target network gateway downlink tunnel upgrades successfully.
In embodiments of the present invention, because data gateway receives the objective network service quality after the objective network mobile management net element of objective network gateway transmission shines upon source network service quality, thereby data gateway need not carry out service quality mapping, avoided the service quality mapping process of on objective network mobile management net element and these two network elements of data gateway, carrying out repetition, thereby can reduce the complexity that product is realized, alleviate the load of product treatment, and then can make that product is easier to realize, and product treatment speeds up.
Wherein, the switching of heterogeneous networks can be the switching of 2G or 3G network and LTE network, general packet radio service technology (General Packet Radio Service for example, abbreviate " GPRS " as) switching of network and System Architecture Evolution (System Architecture Evolution abbreviates " SAE " as) network.The embodiment of the invention will be with subscriber equipment (User Equipment, abbreviating " UE " as) the example that switches in GPRS network and SAE network describes, should be understood that this only is in order exemplarily to describe the present invention, and should not constitute any limitation of the invention.
The network architecture of core network SAE of future generation is shown in Fig. 2 A.Wherein, mobile management net element (MME (Mobility Management Entity, i.e. " mobile management network element ") or S4 SGSN (Serving GPRS Support Node, i.e. " Serving GPRS Support Node ")) location management, connection management, safety certification, the gateway of being responsible for mobile subscriber terminal select (comprise and select gateway, data gateway) etc.; Gateway (SGW (Serving Gateway, i.e. " gateway ")) is that the local access network of user terminal closes; Data gateway (PGW (Packet Data Network Gateway, i.e. " grouped data network gateway ")) is the gateway of user terminal access outer data network; PCRF (Policy andCharging Rules Function, i.e. " policy charging rule functional entity ") as the Control Node of QoS and charging policy, can issue PCC Rule and give PGW, PCC (Policy and Charging Control, i.e. " strategy and charge control ") QCI (QoS Class Identifier in the rule, i.e. " QoS classification logotype "), ARP (Allocation and Retention Priority, promptly " distribute and maintenance priority "), MBR (Maximum Bit Rate, i.e. " maximum bit rate "), GBR parameters such as (Guaranteed Bit Rate, i.e. " assurance bit rates ") has determined that PGW goes up the corresponding qos parameter of carrying; UTRAN is UMTS Terrestrial radio access network (UMTS Terrestrial Radio Access Network), and GERAN is GSM EDGE radio access network (GSM EDGE Radio Access Network).In the SAE framework, the qos parameter in the bearer context of preserving on each network element can be described as " EPS (Evolved PacketSystem, i.e. " evolution packet network ") QoS ", is used for distinguishing mutually with the qos parameter (being called " GPRS QoS ") of GPRS network definition.
The intercommunication of SAE network and GPRS network (being made up of Gn/Gp SGSN and GGSN (Gateway GPRSSupport Node, i.e. " Gateway GPRS Support Node ")) is shown in Fig. 2 B.PGW has the function of GGSN simultaneously as the anchor point of SAE network and GPRS network intercommunication.When the user is linked under the Gn/Gp SGSN scene, the QoS information in the bearer context of the last preservation of PGW is the GPRS qos parameter; After the user switches to the SAE network, the QoS information in the bearer context of the last preservation of PGW will change the EPS qos parameter into.
In another embodiment of the present invention, the method for updating service quality also can comprise:
Determine that described objective network service quality is inconsistent with the service quality in strategy and the charging control rule; And
With described objective network correcting service quality one-tenth and the corresponding to modification of the service quality in described strategy and charging control rule back objective network service quality,
Wherein, the described described source network service quality that will formerly preserve is updated to described objective network service quality and comprises: the described source network service quality that will formerly preserve is updated to described modification back objective network service quality.
Hereinafter will with subscriber equipment by the TAU position more new technological process realize that switching to the EPS network from GPRS network is that example is elaborated, promptly subscriber equipment is updated to S4SGSN or MME from Gn/Gp SGSN position, as shown in Figure 3.
Subscriber equipment (UE) at first sends position updating request (S100) to objective network mobile management net element (S4 SGSN/MME); The objective network mobile management net element receives after the location update request message, sends context request message (S105) to source network mobile management net element (Gn/Gp SGSN); Gn/Gp SGSN receives after the context request message, sends the context acknowledge message that this context request message is responded to S4 SGSN/MME, has wherein carried the QoS of source network (being GPRS network) definition in this context, i.e. GPRS QoS (S110); According to the GPRS QoS that receives, S4SGSN/MME carries out the QoS mapping, and the QoS with the QoS of source network definition is mapped as the objective network definition is about to GPRS QoS and is mapped as EPS QoS (S115); Whether the current source network gateway (SGW) of S4 SGSN/MME decision can continue to serve UE, under the situation of present embodiment, because source network (GPRS) does not have SGW, therefore S4 SGSN/MME just reselects a new SGW (being objective network SGW), send and create conversation request message, to set up the user's bearer context on the objective network SGW, carry the EPS QoS (S120) of S4 SGSN/MME mapping in this establishment conversation request message; Objective network SGW sends first to data gateway (PGW) and revises bearing request message, notice PGW upgrades the downlink tunnel information of preserving, and wherein carries the objective network service quality EPS QoS (S125) of S4 SGSN/MME mapping in this first modification bearing request message.
Owing to carry EPS QoS in this first modification bearing request message, PGW receives the QoS mapping process that can not carry out repetition after this first modification bearing request message, and directly preserve this EPS QoS, the GPRS QoS that is about to formerly preserve is updated to EPS QoS, thereby can transmit accordingly according to EPS QoS, can avoid different network side network elements to carry out the QoS mapping of repetition, thereby can reduce the complexity that product is realized, alleviate the load of product treatment.
Yet, when Gn/Gp SGSN switches to S4 SGSN/MME, carrying ARP (Allocation and Retention Priority after S4 SGSN/MME and the PGW mapping, i.e. " distribute and keep priority ") and the MBR/GBR parameter respectively be kept at PGW on the PCC rule that issues of PCRF in ARP may be different with the MBR/GBR that is tied in the corresponding PCC rule of same bearer, that is to say after the mapping qos parameter may originally to issue the qos parameter that determines in the PCC rule inconsistent with PCRF, the different problem of QoS in this QoS that will cause each network element carrying in the SAE network and the PCC rule that PCRF issues.
For this reason, QoS in the PCC rule that PGW can issue the EPS QoS that receives and PCRF in the embodiment of the invention compares, when determining that EPS QoS and the QoS in the PCC rule are inconsistent, PGW with the EPS QoS that receives be modified as with the PCC rule in also preservation (S130) of corresponding to modifications of QoS back objective network QoS.Thus, the QoS that can guarantee PGW carrying is identical with QoS in the PCC rule that PCRF issues.
In embodiments of the present invention, PGW can send to objective network SGW and revise the first modification bearing response message (S135) of carrying this modification back objective network QoS that bearing request message responds to first, upgrade successfully with notification target network SGW downlink tunnel, objective network QoS passes to objective network SGW and S4 SGSN/MME after the modification that PGW is revised simultaneously, and is identical with QoS in the PCC rule that PCRF issues with the QoS that guarantees each network element carrying in the objective network.Afterwards, objective network SGW can reply S4 SGSN/MME notice bearer context and set up successfully (S145).
On the other hand, PGW also can send the first modification bearing response message that the first modification bearing request message is responded to objective network SGW, and this first modification bearing response message is not carried this modification back objective network QoS (S140); Afterwards, objective network SGW can reply S4 SGSN/MME notice bearer context and set up successfully (S145).In order to make the QoS of each network element carrying in the objective network identical with QoS in the PCC rule that PCRF issues, at this moment, PGW can initiatively initiate the bearing modification flow process, when the QoS that is PGW in determining EPS QoS and PCC rule is inconsistent, initiate first to objective network SGW and upgrade bearing request message, notification target network SGW revises qos value, carries in this first renewal bearing request message and revises back objective network QoS (S150); Objective network SGW sends second to S4 SGSN/MME and upgrades bearing request message after receiving the first renewal bearing request message, and notice S4 SGSN/MME revises qos value (S155); S4 SGSN/MME receives second and upgrades after the bearing request message, the EPS QoS that mapping is in the past obtained is revised as modification back objective network QoS, and can send the second renewal bearing response message that the second renewal bearing request message is responded to objective network SGW, revise successfully (S160) to reply objective network SGW QoS; Objective network SGW can send the first renewal bearing response message that the first renewal bearing request message is responded to PGW, revises successfully (S165) to reply PGW QoS.Thereby, because whether PGW is can the comparison object network QoS consistent with the QoS in the PCC rule, and determining that the two carries out the modification of QoS when not consistent, therefore make the QoS of each network element carrying in the objective network can keep identical, to guarantee unified end to end bandwidth with QoS in the PCC rule that PCRF issues.
The embodiment of the invention also provides a kind of method of updating service quality, and this method comprises:
S50, send first to data gateway and revise bearing request message, the described first modification bearing request message is carried the objective network service quality after the objective network mobile management net element shines upon source network service quality, thereby the described source network service quality that makes described data gateway formerly to preserve is updated to described objective network service quality, and transmits accordingly according to described objective network service quality.
When needing to switch to or position when being updated to the objective network mobile management net element in the switching of UE at heterogeneous networks, carry out more new technological process of switching flow or position from the source network mobile management net element.At this moment, objective network SGW sends first to PGW and revises bearing request message, PGW upgrades downlink tunnel information with notice, this first modification bearing request message is carried the objective network QoS after the objective network mobile management net element shines upon source network service quality, repeats unnecessary mapping to avoid PGW.PGW can directly preserve objective network QoS after receiving this first modification bearing request message, the source network service quality that is about to formerly preserve is updated to objective network service quality, and transmit accordingly according to objective network service quality, and need not carry out the QoS mapping.
In embodiments of the present invention, because the objective network QoS after objective network SGW shines upon the objective network mobile management net element sends to PGW, thereby PGW need not carry out service quality mapping, avoided on a plurality of network elements of objective network, carrying out the service quality mapping process of repetition, thereby can reduce the complexity that product is realized, alleviate the load of product treatment, and then can make that product is easier to realize, and product treatment speeds up.
Yet the qos parameter after the mapping that each network element obtains in the objective network may originally to issue the qos parameter that determines in the PCC rule inconsistent with PCRF, the different problem of QoS in this QoS that will cause each network element carrying in the SAE network and the PCC rule that PCRF issues.
For this reason, the objective network SGW of the embodiment of the invention can receive that PGW sends carry with the PCC rule in corresponding to first of the back objective network QoS that revises of QoS revise bearing response message, make that objective network QoS passes to objective network SGW and objective network mobile management unit after the modification that PGW revises, identical with the QoS that guarantees each network element carrying in the objective network with QoS in the PCC rule that PCRF issues.
Need be when the source network mobile management net element switches to the objective network mobile management net element at UE, the method of the renewal QoS of the embodiment of the invention also can comprise: what receive the data gateway transmission revises the first modification bearing response message that bearing request message responds to first, this first revise bearing response message carry with strategy and charging control rule in corresponding to modifications of service quality back objective network service quality, thereby according to revising the back objective network service quality renewal objective network service quality of preservation formerly.The method of the renewal QoS of the embodiment of the invention also can comprise: receive the first modification bearing response message of carrying modification back objective network QoS of PGW transmission at objective network SGW after, the second modification bearing response message that the second modification bearing request message that the objective network mobile management net element is sent to the transmission of objective network mobile management net element responds, this second modification bearing response message is carried this modification back objective network service quality, makes the objective network mobile management net element upgrade the objective network service quality of preservation formerly according to revising back objective network service quality.Thereby make the QoS of each network element carrying in the objective network identical with QoS in the PCC rule that PCRF issues.
On the other hand, the first modification bearing response message that receives the PGW transmission at objective network SGW is not carried under the situation of revising back objective network QoS, method according to the renewal QoS of the embodiment of the invention can also comprise the bearing modification flow process that PGW initiatively initiates, to revise the QoS of each network element, this flow process comprises: receive the first renewal bearing request message that PGW sends, this first upgrade bearing request message carry with the PCC rule in corresponding to modifications of QoS back objective network QoS, thereby upgrade the objective network QoS of preservation formerly according to revising back objective network QoS; Send second to the objective network mobile management net element and upgrade bearing request message, this second renewal bearing request message is carried described modification back objective network service quality, makes the objective network mobile management net element upgrade the objective network QoS of preservation formerly according to revising back objective network QoS; What receiving target network mobile management net element sent upgrades the second renewal bearing response message that bearing request message responds to second; And to PGW send to first upgrade that bearing request message responds first upgrade bearing response message.Therefore, the QoS of each network element carrying can keep identical with QoS in the PCC rule that PCRF issues in the objective network, to guarantee unified end to end bandwidth.
Hereinafter will realize that by switching flow switching to the EPS network from GPRS network is that example is elaborated, shown in Fig. 4 A and 4B with subscriber equipment.
After the UE decision triggers and switches (S200), the source network access network elements sends handoff request message (S205) to source network mobile management net element (Gn/Gp SGSN), change handoff request message before Gn/Gp SGSN select target network mobile management net element (S4 SGSN/MME) sends, carry anchor point data gateway (PGW) address information (S210) in this message.Whether the current source network SGW of S4 SGSN/MME decision can continue to serve UE, if it is not all right, just reselect a new gateway (being the objective network gateway), send and create conversation request to objective network SGW (S215), objective network can be replied and be created conversational response message (S220).Change switching response message before S4 SGSN/MME can return and give Gn/Gp SGSN (S225).If data forwarding adopts non-immediate data to transmit, then make up non-immediate data and transmit passage (S230).Gn/Gp SGSN order source network access network elements begins to switch (S235), so source network access network elements notice UE begins to switch (S240).Source access network (GPRS) begins to transmit data to objective network (SAE) (S245), so UE successfully inserts objective network SAE (S250).
The objective network access network elements inserts in order to prove conclusively UE, sends switching notice to S4 SGSN/MME (S255).Commentaries on classics handoff completion message notice Gn/Gp SGSN (S260) changeed before Gn/Gp SGSN can return to switch and finishes acknowledge message to S4 SGSN/MME (S265) before S4 SGSN/MME sent.S4SGSN/MME sends second and revises bearing request message to objective network SGW, upgrades user plane bearer information (S270).Similar with the flow process that adopts the position to upgrade, objective network SGW sends first to PGW and revises bearing request message, notice PGW upgrades the downlink tunnel information of preserving, and wherein carries the objective network service quality EPSQoS (S275) of S4 SGSN/MME mapping in this first modification bearing request message.
Owing to carry EPS QoS in this first modification bearing request message, PGW can not carry out the QoS mapping process of repetition, directly preserve this EPS QoS, the GPRS QoS that is about to formerly preserve is updated to EPS QoS, and transmit accordingly according to EPS QoS, can avoid different network side network elements to carry out the QoS mapping of repetition, thereby can reduce the complexity that product is realized, alleviate the load of product treatment.Meanwhile, QoS in the PCC rule that PGW can issue the EPS QoS that receives and PCRF compares, when determining that the two is inconsistent, PGW with the EPS QoS that receives be modified as with the PCC rule in corresponding to modifications of QoS back objective network QoS and preservation (S280).Thus, the embodiment of the invention QoS that can also guarantee PGW carrying is identical with QoS in the PCC rule that PCRF issues.
In embodiments of the present invention, PGW can send the first modification bearing response message (S285) of carrying this modification back objective network QoS to objective network SGW, afterwards, objective network SGW can send second to S4SGSN/MME and revise bearing response message, set up successfully with the notice bearer context, this second modification bearing response message is carried this modification back objective network QoS (S290), thereby objective network QoS passes to objective network SGW and S4 SGSN/MME after the modification that PGW is revised, and is identical with QoS in the PCC rule that PCRF issues with the QoS that guarantees each network element carrying in the objective network.
On the other hand, PGW also can send the first modification bearing response message (S295) of not carrying this modification back objective network QoS to objective network SGW; Objective network SGW does not carry second of this modification back objective network QoS can for S4 SGSN/MME transmission and revise bearing response message (S300).At this moment, in order to make the QoS of each network element carrying in the objective network identical with QoS in the PCC rule that PCRF issues, PGW can initiatively initiate the bearing modification flow process, be that PGW initiates the first renewal bearing request message to objective network SGW, notification target network SGW revises qos value, carries in this first renewal bearing request message and revises back objective network QoS (S305); Objective network SGW sends second to S4 SGSN/MME and upgrades bearing request message after receiving the first renewal bearing request message, and notice S4 SGSN/MME revises qos value (S310); S4 SGSN/MME receives second and upgrades after the bearing request message, the EPS QoS that mapping is in the past obtained is revised as modification back objective network QoS, and can send the second renewal bearing response message that the second renewal bearing request message is responded to objective network SGW, revise successfully (S315) to reply objective network SGW QoS; Objective network SGW also can send the first renewal bearing response message that the first renewal bearing request message is responded to PGW, revises successfully (S320) to reply PGW QoS.Thereby the QoS of each network element carrying can keep identical with QoS in the PCC rule that PCRF issues in the objective network, to guarantee unified end to end bandwidth.
The embodiment of the invention also provides a kind of network equipment 100 that is used for updating service quality, and as shown in Figure 5, this network equipment 100 comprises first receiver module 110 and update module 120.Wherein, first receiver module 110 is used for the first modification bearing request message that receiving target network gateway sends, and this first modification bearing request message is carried the objective network service quality after the objective network mobile management net element shines upon source network service quality; The source network service quality that update module 120 is used for formerly preserving is updated to objective network service quality, thereby transmits accordingly according to objective network service quality.This network equipment 100 for example is a data gateway.
In embodiments of the present invention, because first receiver module 110 receives the objective network service quality after the mapping of objective network mobile management net element that the objective network gateway sends, thereby network equipment 100 need not carry out service quality mapping, avoided the service quality mapping process of on objective network mobile management net element and these two network elements of data gateway, carrying out repetition, thereby can reduce the complexity that product is realized, alleviate the load of product treatment, and then can make that product is easier to realize, and product treatment speeds up.
In another embodiment of the present invention, the network equipment 100 that is used for updating service quality also can comprise determination module 130 and modified module 140, as shown in Figure 6.Wherein, determination module 130 is used for determining that objective network service quality is inconsistent with the service quality of strategy and charging control rule; Modified module 140 is used for the objective network correcting service quality is become and the corresponding to modification of the service quality of strategy and charging control rule back objective network service quality, and the source network service quality that update module 120 will formerly be preserved is updated to modification back objective network service quality.
