Abstract
Obtaining message of QoS information, building message of QoS information and updating message of QoS information, the method transfers source QoS information to destination radio network (RN) the mobile terminal is going to switch to, and transfers QoS information allowed by destination RN to source RN so as to ensure consistency of QoS of service before and after switching and allotting resources reasonably. After fast switch over between PDSN occurs at mobile terminal, if mobile terminal initiates new operation application, the destination RN can accomplishes QoS authentication of new built service, admittance control, QoS negotiation, resources allocation, and determines whether access of the new built service is allowed locally based on source QoS information received at the said switching procedure without need of RN side to take part in. advantages are: increasing speed of negotiation, and guaranteeing QoS of service.
Description
Technical field
The present invention relates to wireless network traffic, refer to a kind of method of between packet data serving node (PDSN), setting up service quality (Qos) information in quick the switching especially.
Background technology
Third generation partner program II (3GPP2) HRPD (high rate packet data) (HRPD) Rev.0 agreement and 3GPP2 HRPD Rev.A agreement, described when one or more business are in activation (Active) state, professional packet domain handoff procedure between PDSN, but the creating a mechanism of Qos of service after switching is not provided.
From the angle of PDSN, packet domain is switched to have in the PDSN and is switched between switching, PDSN, is also referred to as non-quick switching between PDSN, reaches between PDSN and switch three kinds fast.Wherein, switching fast between PDSN is to realize that by the P-P interface between source PDSN (Server PDSN) and purpose PDSN (Target PDSN) purpose wireless network (Target RN) utilizes R-P interface and the above-mentioned P-P interface set up between Target RN and the Target PDSN to transmit data message between portable terminal (MS) and Server PDSN.
With MS example taking place between PDSN to switch to fast, describes existing handoff procedure below.Fig. 1 a is a syndeton schematic diagram before switching fast between the PDSN that defines in the prior art 3GPP2 agreement, as shown in Fig. 1 a, PDSN is the IAD that connects RN and Packet Data Network, for mobile Internet/Intranet terminal provides the grouped data access service, from Fig. 1 a as seen, set up R-P between MS and the ServerRN and be connected, and in Server RN coverage, commenced business.When MS takes place to Target RN direction mobile, trigger the handoff procedure between Server PDSN and the Target PDSN.
Fig. 1 b switches back syndeton schematic diagram fast between the PDSN that defines in the prior art 3GPP2 agreement, shown in Fig. 1 b, after switching, Server RN is to the Target RN notice that switches, and illustrates that MS will switch to from the scope that Server RN is covered in the scope that Target RN covered; Target RN sets up purpose R-P interface after receiving the notice that switches between Target RN and Target PDSN, promptly set up being connected between Target RN and the Packet Data Network by Target PDSN; Afterwards, set up purpose P-P interface between Target PDSN and Server PDSN, Server PDSN manages portable terminal by the P-P interface; At last, the source R-P interface between dismounting Server RN and the Server PDSN.After finishing said process, MS carries on business in Target RN coverage.
Fig. 2 is the flow chart that switches and switch the back new business between existing techniques in realizing PDSN fast, in conjunction with Fig. 1, supposes that MS in Server RN coverage, has set up srvice instance with Server PDSN.This srvice instance is in the Active state, and MS is in Target RN moves to the coverage of Target RN, and this switching is to switch fast between PDSN, and concrete job step is as follows:
Step 200:Server RN is to the Target RN notice that switches.
In this step, comprise some characteristic informations of the MS that switches and the former wireless network at this MS place etc. in the notice that switches.Here, the roaming that the source radio network at MS place is also referred to as MS goes out ground, and the purpose RN that MS switches to is also referred to as and is roamed into ground.
Set up between step 201～step 202:MS and the Target RN and eat dishes without rice or wine and distribute interface-free resources, between Target RN and Target PDSN, set up purpose R-P interface afterwards.
3GPP2 standard R-P interface is the signaling interface of RN and PDSN, mainly contains four message on this R-P interface.Wherein, A11 sets up request (A11 Registration Request) message and A11 sets up response (A11 Registration Reply) message, be used for newly-built, safeguard the A10 link between RN and the PDSN; A11 sets up and upgrades (A11 Registration Update) message and A11 foundation affirmation (A11Registration Acknowledge) message, is used for PDSN and initiates to remove the A10 link to RN.Above-mentioned message structure sees also 3GPP2 A.S0017 agreement.
In this step, after Target RN receives the notice that switches, set up between MS and the Target RN and eat dishes without rice or wine to be connected, and distributed interface-free resources, comprise the resource contents such as Qos (Target Granted Qos) information of purpose network permission in the interface-free resources; Target RN sends A11 Registration Request message to Target PDSN afterwards, and the R-P interface is set up in request; After Target PDSN receives this request message, send A11 Registration Reply message, finish the foundation of purpose R-P interface to Target RN.
In above-mentioned A11 Registration Request message, carried the indication that to set up P-P interface between Target PDSN and Server PDSN.
Step 203～step 204: between Target PDSN and Server PDSN, set up purpose P-P interface.
3GPP2 standard P-P interface is the signaling interface of Server PDSN and Target PDSN, mainly contains four message on this P-P interface.Wherein, P-P sets up request (P-P Registration Request) message and P-P sets up response (P-P Registration Reply) message, be used for newly-built, safeguard the P-P link between Target PDSN and the Server PDSN; (P-P Registration Update) message is upgraded in the P-P request and (P-P Registration Acknowledge) message is confirmed in the P-P request, is used for Server PDSN and initiates to remove the P-P link to Target PDSN.Above-mentioned message structure sees also 3GPP2 A.S0017 agreement.
In this step, the indication that Target PDSN sets up the P-P interface according to the needs that carry in the A11 Registration Request message sends P-P Registration Request message to Server PDSN, and the P-P interface is set up in request; After Server PDSN receives this request message, send P-PRegistration Reply message, finish the foundation of purpose P-P interface to Target PDSN.
So far, set up new service bearer passage at the purpose network, the business between MS and the Server PDSN can carry on.
What deserves to be mentioned is, from the flow process of switching fast between above existing techniques in realizing PDSN, after not considering to take place to switch fast between PDSN, the consistency of Qos before and after whether guaranteeing to switch.When particularly the Qos after switching can not satisfy the required Qos of the former business of MS, do not provide complete Qos to authorize and the mechanism of access control, can't guarantee the portable terminal quality that business is carried out in the purpose network.
Wherein the dismounting of R-P interface is finished by A11 Registration Update message and A11 RegistrationAcknowledge message; The dismounting of P-P interface is finished jointly by P-P Registration Update message and P-PRegistration Acknowledge message.Specific implementation belongs to existing 3GPP2X.P0011-004-D agreement specified content, no longer repeats here.
From above-mentioned prior art as can be seen, when prior art takes place to switch fast between PDSN in business, exist the Target PDSN and the Target RN that are roamed into ground can't obtain from the source Qos information of roaming out ground, thus the consistency of professional Qos and reasonable resources distribution before and after can't guaranteeing to switch.
Source described here Qos information spinner will comprise: Qos (ServerAuthorize Qos) information that authorize in Qos (Server Granted Qos) information that source Qos configuration file (Server Qos Profile) information, source allow and source.
Wherein, Server Qos Profile be the user when opening an account, by the business hall system typing and be stored in the Qos information of Authorization, Authentication and Accounting (AAA) server, this Server Qos Profile is the Qos information of a static state.This Server Qos Profile mainly comprises user name, user cipher, allow user's limits value of access, professional and the professional maximum bandwidth that this user who allows carries out, the ID of this configuration file, the interface-free resources of this Server Qos Profile correspondence, the differentiated service label that allows, the business option that allows, Streaming Media (TFT) maximum number that allows, the maximum bandwidth that each user allows, the maximum application fluxion amount that each user allows, the ID tabulation of the air interface Qos configuration file that allows, the air interface qos parameter that is authorized to, the limit priority that each stream is allowed to does not wait.
Server Granted Qos is when setting up new business, after the RN side obtains above-mentioned Server QosProfile, the Qos that RN obtains after dynamically adjusting according to the Qos parameter of eating dishes without rice or wine of ID correspondence among this Server Qos Profile, the actual interface-free resources of having set up etc.
For business such as streaming media service, video sessions, need Server Authorize Qos be issued to PDSN from the policy deciding functional entity (PDF) of multimedia domain, MMD, Server Authorize Qos is the result of multimedia domain, MMD and application server or opposite end resource negotiation in the service bearer control procedure.
In addition, even the Qos after switching can satisfy the MS required Qos that commences business,, then need carry out complete negotiations process according to 3GPP2X.P0011-004-D agreement regulation to the negotiation of Qos if MS need initiate a new business example, in conjunction with shown in Figure 2, this process roughly may further comprise the steps:
Step 205:MS initiates the new business example according to concrete type of service.
In this step, MS initiates new service request by R-P interface and P-P interface to Server PDSN, and specific implementation and existing 3GPP2X.P0011-004-D agreement regulation are in full accord, and no longer amount is stated here.
Step 206:Server PDSN is to aaa server application Qos user profile (Qos UserProfile), and by main business example purpose P-P interface and purpose R-P interface the Qos UserProfile that obtains sent to Target PDSN and Target RN.
Step 207:Target RN finishes the Qos authentication and the access control of new business according to the Qos User Profile that receives, and carries out Qos and consult and resource allocation.
Step 208～step 209: the R-P that sets up this new business between Target RN and Target PDSN is connected, and the P-P that sets up this new business between Target PDSN and Server PDSN is connected, and whether ruling allows the access of new business.If satisfy access conditions, then allow the access of new business; Otherwise do not allow.
It is in full accord that the R-P that sets up this new business in this step connects realization and the step 201～step 204 be connected with P-P, no longer repeats here.
Step 210: for business such as streaming media service, video sessions, Server PDSN applies for Server Authorize Qos to PDF, and is issued to Target RN.
Step 211:, then upgrade Granted Qos with Server Authorize Qos if the Target Granted Qos that sets up when eating dishes without rice or wine is better than Server AuthorizeQos.
Carrying out flow template (TFT) between step 212:MS and the Server PDSN consults.
After the completing steps 205～step 212, if consult successfully, then MS carries on new business, otherwise, remove connection according to 3GPP2 X.P0011-004-D agreement regulation.
Need to prove that the specific implementation of step 205～step 210 sees also the concrete regulation of 3GPP2X.P0011-004-D agreement.What emphasize here is, in the prior art, after business carries out switching fast between PDSN, if initiation new business, need carry out the complete Qos negotiations process of an agreement regulation, in the Qos negotiations process, Target PDSN and Target RN need obtain Qos Profile and Authorize Qos from ServerPDSN, carry out Qos authentication and access control according to the information that obtains then, this process is consuming time longer.
Method flow from above-mentioned prior art, finish above-mentioned MS after the process of switching fast between PDSN, do not consider the consistency problem of activating service Qos before and after switching at present in the agreement, exist the Target PDSN and the Target RN that are roamed into ground can't obtain from the source Qos information of roaming out ground, thus the consistency of professional Qos and reasonable resources distribution before and after can't guaranteeing to switch.
In addition, after switching fast between PDSN, need carry out complete Qos negotiations process for the new business example, consuming time longer.

Embodiment
Core concept of the present invention is: by obtaining the Qos informational message, setting up the Qos informational message source Qos information is passed to the purpose wireless network that portable terminal switches to, and the consistency of professional Qos before and after having guaranteed to switch.
Fig. 3 is a flow chart of setting up Qos information between PDSN during the present invention is switched fast, and when portable terminal occurs in when switching fast between PDSN, the inventive method may further comprise the steps:
Step 300: purpose RN is according to the notice that switches from source RN that receives, set up between portable terminal and the purpose RN eat dishes without rice or wine and purpose RN and purpose PDSN between the R-P interface, and indicate to purpose RN and to set up the P-P interface.
The realization of this step belongs to existing known technology, and specific implementation can no longer repeat here referring to existing 3GPP2X.P0011-004-D agreement regulation.
Step 301: purpose PDSN sets up the P-P interface between purpose PDSN and the source PDSN according to indication, source Qos information is carried at obtain simultaneously to send to purpose PDSN in the Qos informational message.
In this step, obtaining the Qos informational message can be existing message, as P-P Registration Reply message, also can be to be specifically designed to source Qos information is obtained message from the special use that source PDSN is sent to purpose PDSN.
Step 302: purpose PDSN is carried at the source Qos information that receives to set up and sends to purpose RN in the Qos informational message.
In this step, setting up the Qos informational message can be existing message, as A11 RegistrationUpdate message, also can be to be specifically designed to source Qos information is set up message from the special use that purpose PDSN is sent to purpose RN.
Step 303～step 305: purpose RN judges according to the source Qos information that receives whether the interface-free resources of having set up can satisfy the demand of source Qos information, if can not satisfy, then removes purpose and connects, process ends after the release resource; If can satisfy, then portable terminal carries on current business by R-P interface and the P-P interface of having set up.
In this step, the comparative approach of the source Qos information that receives and the interface-free resources of having set up is: if the Qos that purpose allows in the interface-free resources is better than the Qos that the source allows in the Qos information of source, judge that then interface-free resources that purpose RN has set up can satisfy the demand of source Qos information; Otherwise, for not meeting the demands.
Wherein, remove the purpose connection and comprise the interface-free resources that release has distributed and remove purpose R-P interface and the purpose P-P interface of having set up, the method for dismounting belongs to prior art, removes connection according to existing 3GPP2X.P0011-004-D agreement regulation and gets final product.
Need to prove, when the Qos of purpose permission in the interface-free resources is better than the Qos of source permission in the Qos information of source, this method also comprises following processing: the Qos that allows as if purpose in the interface-free resources also is better than the Qos that authorize in the source in the Qos information of source, then the purpose RN local interface-free resources of source Qos information updating; Otherwise, can upgrade, can not upgrade yet.
After if the above-mentioned Qos that satisfies purpose permission in the interface-free resources is better than the condition of the Qos that the source allows in the Qos information of source, all take the purpose RN local interface-free resources of source Qos information updating, portable terminal carries on current business by R-P interface and the P-P interface of setting up.
Like this, when interface-free resources is better than the demand of source Qos,, guaranteed the reasonable use of purpose interface-free resources by adjusting interface-free resources; In addition when the interface-free resources of purpose wireless network can not satisfy business need, disconnect being connected of portable terminal and purpose wireless network as early as possible, guaranteed the quality that portable terminal is commenced business in the purpose wireless network.
In addition, satisfy the demand of source Qos information in the interface-free resources of having set up, portable terminal carries on before the business, the inventive method also comprises: whether the Qos of the purpose permission in the interface-free resources that purpose RN judgement has been set up is consistent with the Qos that the source in the Qos information of source allows, if unanimity, then process ends; If inconsistent, then purpose RN Qos information that purpose is allowed is carried to upgrade in the Qos informational message and sends to source PDSN.Portable terminal carries on current business by R-P interface and the P-P interface of setting up.
Here, owing to the Qos information that purpose allows has been sent to source PDSN, guaranteed the charging of source PDSN by upgrading the Qos informational message.
Upgrading the Qos informational message can be existing message, send to purpose PDSN as carry the Qos information that purpose allows by A11 Registration Request message from purpose RN, carry the Qos information that the purpose that receives allows by P-P RegistrationReply message again and send to source PDSN; Also can be two special-purpose updating message that are exclusively used in the Qos information that sends the purpose permission, wherein special-purpose updating message one is used to carry the Qos information that purpose allows and sends to purpose PDSN from purpose RN, and special-purpose updating message two is used to carry the Qos information that the purpose that receives allows and is sent to source PDSN from purpose PDSN.
During switching fast, the above-mentioned the present invention of being sets up the method for Qos information between PDSN, this method passes to the purpose wireless network that portable terminal switches by obtaining the Qos informational message, set up the Qos informational message and upgrading the Qos informational message with source Qos information, and the Qos information that the purpose wireless network is allowed passes to source radio network, consistency and the reasonable resources distribution of professional Qos before and after having guaranteed to switch.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Realize that with the function that adopts message in the expansion prior art the inventive method is an example, describe the inventive method in detail.Fig. 4 is the embodiment flow chart that the present invention realizes switching and switching fast between PDSN the back new business, in conjunction with Fig. 1, supposes that MS in Server RN coverage, has set up srvice instance with Server PDSN.This srvice instance is in the Active state, and MS switches in the Target RN coverage, and has taken place to switch fast between PDSN.It is as follows to describe concrete job step in detail:
Step 400:Server RN is to the Target RN notice that switches.
The realization and the prior art of this step are in full accord, no longer repeat here.
Set up between step 401～step 402:MS and the Target RN and eat dishes without rice or wine, and between Target RN and Target PDSN, set up purpose R-P interface by A11 Registration Request message.
The realization of this step and prior art step 201～step 202 are in full accord, no longer repeat here.
The indication consistent with prior art, that the needs that carried in A11 Registration Request message are set up the P-P interface.

In this step, the indication that Target PDSN sets up the P-P interface according to the needs that carry in the A11 Registration Request message, Target PDSN sends P-P RegistrationRequest message to Server PDSN, and the P-P interface is set up in request; After Server PDSN receives this request message, send the P-P Registration Reply message of carrying source Qos information, finish the foundation of purpose P-P interface to TargetPDSN.
Unlike the prior art be that the P-P Registration Reply message in this step has also been carried source Qos information as obtaining the Qos informational message except as setting up the response message of P-P interface.Here, P-P Registration Reply message is expanded, newly-increased application type (ApplicationType) field, this Application the type field comprises three application sub-types (Application SubType) field: the Qos Profile field that is used to store Qos Profile information, be used to the Authorize Qos field of storing the Granted Qos field of GrantedQos information and being used to store Authorize Qos information.
Wherein, the Server Qos Profile information in the source Qos information is carried in the Qos Profile field; Server Granted Qos information in the Qos information of source is carried in the Granted Qos field; Server Authorize Qos information in the Qos information of source is carried in the Authorize Qos field.
Step 405:Target PDSN is carried at the source Qos information that receives in the A11 RegistrationUpdate message and is handed down to Target RN.
In this step, Target PDSN adopts existing A11 Registration Update message as setting up the Qos informational message, source Qos information is carried in this A11 Registration Update message sends to Target RN.Wherein, the Server Qos Profile information in the Qos information of source, only sending wherein, the parameter of Target RN needs gets final product.The Qos parameter that the RN side needs mainly comprises: the maximum bandwidth that each user allows, the maximum application fluxion amount that each user allows, the ID tabulation of the air interface QoS configuration file that allows, the air interface qos parameter that is authorized to, the limit priority that each stream is allowed to does not wait.
Here, A11 Registration Update message is expanded, newly-increased Application the type field, this Application the type field comprises three Application Sub the type fields: the Qos Profile field that is used to store Qos Profile information, be used to the Authorize Qos field of storing the GrantedQos field of Granted Qos information and being used to store Authorize Qos information.
Wherein, the parameter of the needs of the Target RN in the Server Qos Profile information is carried in the QosProfile field; Server Granted Qos information is carried in the Granted Qos field; ServerAuthorize Qos information is carried in the Authorize Qos field.
Step 406: according to the source Qos information that receives, Target RN judges whether the interface-free resources set up can satisfy the required Qos of current business, if can not satisfy, then removes process ends after the purpose wireless connections; If can satisfy, then enter step 407.
In this step, the comparative approach of the source Qos information that receives and the interface-free resources of having set up is: if the purpose Granted Qos in the interface-free resources is better than the Server Granted Qos in the Qos information of source, judge that then interface-free resources that purpose RN has set up can satisfy the demand of source Qos information; Otherwise, for not meeting the demands.
Wherein, when the purpose Granted Qos in the interface-free resources is better than ServerGranted Qos in the Qos information of source, before entering step 305, also comprise following processing: if the purpose Granted Qos in the interface-free resources also is better than Server Authorize Qos in the Qos information of source, then purpose RN is with the local interface-free resources of source Qos information updating; Otherwise, can upgrade, can not upgrade yet.
Like this, when interface-free resources is better than the demand of source Qos,, guaranteed the reasonable use of purpose interface-free resources by adjusting interface-free resources; In addition when the interface-free resources of purpose wireless network can not satisfy business need, disconnect being connected of portable terminal and purpose wireless network as early as possible, guaranteed the quality that portable terminal is commenced business in the purpose wireless network.
Step 407:Target RN judges whether the Target Granted Qos in the interface-free resources of having set up is consistent with the Server Granted Qos in the Qos information of source, if unanimity, then process ends; If inconsistent, then enter step 408.
Step 408～step 409:Target RN is carried at Target Granted Qos information in the A11Registration Request message, send to Target PDSN, Target PDSN is carried at the Target Granted Qos that receives in the P-P Registration Request message again, sends to ServerPDSN.
In this step, P-P Registration Request message is expanded, newly-increased ApplicationType field, this Application the type field comprises three Application Sub the type fields: the Qos Profile field that is used to store Qos Profile information, be used to the Authorize Qos field of storing the Granted Qos field of Granted Qos information and being used to store Authorize Qos information.
Wherein, the Server Qos Profile information in the source Qos information is carried in the Qos Profile field; Server Granted Qos information in the Qos information of source is carried in the Granted Qos field; Server Authorize Qos information in the Qos information of source is carried in the Authorize Qos field.Need to prove that newly-increased Application the type field can include only the Granted Qos field of storage Granted Qos information in the described P-P Registration Request message.
Expanding to of A11 Registration Request message: newly-increased Application the type field, this Application the type field comprises three Application Sub the type fields: the Qos Profile field that is used to store QosProfile information, be used to the Authorize Qos field of storing the Granted Qos field of Granted Qos information and being used to store Authorize Qos information.Need to prove that newly-increased Application the type field can include only the Granted Qos field of storage Granted Qos information in the described A11 Registration Request message.
So far, set up the wireless connections between MS and the Target PDSN, simultaneously, also set up the Qos of this MS business in the purpose wireless network, MS can commence business smoothly in that the purpose network trunk is continuous.
From foregoing description as seen, expansion by existing P-P Registration Reply message, A11 RegistrationRequest message and A11 Registration Update message, increased the field of carrying source Qos information, source Qos information is passed to the purpose wireless network that portable terminal switches, and consistency and the reasonable resources of professional Qos are distributed before and after having guaranteed to switch.
After MS switched to the purpose network, if MS need initiate a new business example, then the negotiation to the Qos of new business may further comprise the steps:
Step 410:MS initiates the new business example according to concrete type of service.
In this step, MS initiates new service request by R-P interface and P-P interface to Server PDSN, and specific implementation and existing 3GPP2 X.P0011-004-D agreement regulation are in full accord, no longer repeat here.
Step 411:Target RN finishes the Qos authentication and the access control of new business according to the source Qos information that receives, and carries out Qos and consult and resource allocation.
In this step, the direct Qos information of Target RN according to this portable terminal of in the purpose wireless network, setting up, carry out the Qos authentication and the access control of new business, and need not to obtain Server Qos Profile information and Server Granted Qos information from AAA and PDF.
What emphasize here is, the source of source Qos information directly obtains from this locality, specifically how to finish the Qos authentication and the access control of new business, and carries out that Qos consults and resource allocation can be stipulated referring to existing 3GPP2X.P0011-004-D agreement, no longer repeats here.
Step 412: set up eating dishes without rice or wine and the R-P interface of new business, and the TargetGranted Qos information in the interface-free resources is carried in the A11 Registration Request message, send to TargetPDSN.
Step 413:Target PDSN is according to the source Qos information that receives in handoff procedure, and whether ruling allows the access of new business.If satisfy access conditions, then allow the access of new business; Otherwise do not allow.
This step is under following situation.Do not satisfy access conditions, Target PDSN refusal inserts new business:
(1) user's linking number surpasses limits value, this value subscriber service class tabulation;
(2) the new business example in the subscriber service class tabulation, do not tabulate by subscriber service class listuser class of service;
(3) Target PDSN does not have enough R-P resources, and Target PDSN is clearly to own resources.
In the processing of this step, increased the access control of Target PDSN, can guarantee that follow-up business carries out smoothly.Particularly above (1) and (2) realizes that at Target PDSN near-end access control is than more reasonable in far-end Server PDSN realization.
Carrying out flow template (TFT) between step 414:MS and the Sserver PDSN consults.
The realization of this step can no longer repeat here referring to existing 3GPP2 X.P0011-004-D agreement regulation.
From step 410～step 414 as can be seen, the quick switching of PDSN takes place after, MS initiates the new business application, Target RN only needs according to the source Qos information that receives in above-mentioned handoff procedure, finish in this locality the Qos authentication of new business and access control, Qos negotiation and resource allocation, and ruling whether allow the access of new business, need not participation by the source radio network side.This method has improved the speed that new business Qos consults, and simultaneously, has also guaranteed the quality of new business.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
