Description

Internal interface data path characteristics method of adjustment and network in a kind of wireless access network
Technical field
The present invention relates to the communications field, relate in particular to internal interface data path characteristics method of adjustment and network in a kind of wireless access network.
Background technology
Extensive use along with the flourish and wireless network of internet service, GPRS (GPRS, GPRS General Packet Radio Service), 3-G (Generation Three mobile communication system) (3G), micro-wave access to global intercommunication (WiMAX, Worldwide Interoperability for Microwave Access) and back 3G wireless systems such as (B3G, Beyond 3G) obtained a large amount of application and concern.The increase of number of users and the increase of user's request provide new demand for wireless access network system: requirement can be supported big capacity, the multiple business that big data quantity and different service quality require.
Wireless access network finishes mainly that the Packet Service that provides between network and the mobile subscriber is transmitted or the function of route.Do not consider other internal units in the Access Network, we will be example (technology provided by the present invention includes but not limited to the application in the WiMAX system) with WiMAX network architecture system shown in Figure 1 when technical description subsequently.The function of each network element among Fig. 1 is as follows:
Access service network (ASN, Access Service Network): ASN is defined as the network function set that the wireless access service is provided for the WiMAX terminal, ASN has comprised base station (BS, Base Station) and access service network gateway (ASN-GW, Access Service Network Gate Way) network element.ASN mainly provides following function:
The function of BS:
-layer 2 of BS and mobile subscriber station (MSS, Mobile Subscribe Station) is provided, and (L2 Layer2) connects;
The function of ASN-GW:
-for MSS provide the layer 3 (L3, Layer 3) information relaying (Relay) function (as IP address assignment);
-RRM;
Connectivity serving network (CSN, Connectivity Service Network): CSN is defined as to the WiMAX terminal IP is provided Connection Service.CSN mainly provides following function:
-ASN is to the tunnel of CSN, be equivalent in the mobile IP technology home agent (HA, HomeAgent);
-WiMAX user's charging and the clearing between the operator;
Tunnel under the-roaming condition between the CSN;
Switching between the-ASN;
MSS:MSS is a mobile subscriber equipment, and the user uses this devices accessing WiMAX network.
From data surface, the grouping busihess data of descending MSS newspaper from the HA of CSN by the Interface R3 between the ASN-GW HA and the ASN (being referred to as anchor ASN-GW), be sent among the ASN, and send on the MSS through the R6 interface between inner ASN-GW of ASN and the BS and the R1 interface between BS and the MSS data MSS by ASN-GW.If the ASN-GW (being referred to as to serve ASN-GW) of the BS that ASN-GW that links to each other with HA among the CSN and control MSS insert is not simultaneously, the grouping busihess data of descending MSS newspaper from the HA of CSN by the Interface R3 between the ASN-GW HA and the ASN, be sent among the ASN, and send on the MSS through the R6 interface between Interface R4, ASN-GW and the BS between inner ASN-GW of ASN and the ASN-GW and the R1 interface between BS and the MSS data MSS by ASN-GW.Upstream data then is delivered to the CSN along opposite path from MSS and reaches end subscriber.As mentioned above, the data path that corresponding uplink and downlink is all arranged for each Business Stream of each MSS in the interface of ASN inside, these all can require according to the service quality (QoS) of each Business Stream when each Business Stream is set up and the employing mode of data path is set up.When this service ending, when just Business Stream is ended, just need to discharge corresponding data path.
But carry out in the process in business, because the change of the demand of upper layer application or network characteristic, Internet resources operating position, all will cause the change of dynamic traffic characteristics (such as bandwidth, delay requirement, shake and Business Stream RM, data path self characteristics or the like), so just need to adjust data path characteristics corresponding on the ASN internal interface (comprise the data path self characteristics and to the support of the characteristic changing of its institute's loaded service stream).
For foundation and the release of supporting data path, prior art has defined following primitive and has been used in R6 path between BS and the ASN-GW, the R4 path between the ASN-GW.
Message primitive From->To Message content
Data Path Establishment Request (data path is set up request) BS<->ASN GW； ASN-GW<->ASN GW The MSS sign, one group of { session identification, data path information is in order to discern the classified information of this Business Stream } that need set up
Data Path Establishment Response (data path is set up response) ASN GW<->BS； ASN-GW<->ASN GW The MSS sign, one group of { session identification, data path information is in order to discern the classified information of this Business Stream } that need set up
Data Path Establishment Ack (data path is set up and confirmed) BS<->ASN GW； ASN-GW<->ASN GW The MSS sign, one sets up upright good { session identification }
Data Path Release Request (data path discharges request) BS<->ASN GW； ASN-GW<->ASN GW The MSS sign, one group of { session identification } that need discharge data path
Data Path Release Response (data path discharges response) ASNGW<->BS； ASN-GW<->ASN GW The MSS sign, one group of { session identification } that need discharge data path
Wherein, Data Path Establishment Request is the service channel that is used for setting up one group of unidirectional MSS, is used for the receiving terminal of notification message to identify the transmitting terminal that according to the path of appointment this datagram is forwarded to this message after the packet datagrams of MSS session receiving.
Wherein, Data Path Establishment Response is after receiving data path foundation request, be used for setting up one group of reverse MSS service channel, be used for notifying the transmitting terminal that according to the path of appointment this datagram is forwarded to this message after the receiving terminal of Data Path EstablishmentResponse message identifies the MSS session receiving the packet datagrams.This packet datagrams is according to the classified information Classification and Identification of Business Stream.
At last, confirm that by Data Path Establishment Ack message whole data path sets up finishing of process, comprise in the message and set up good session identification.
In the data path dispose procedure, Data Path Release Request is the service channel that is used for discharging one group of unidirectional MSS.
Wherein, Data Path Release Response is after receiving data path release request, is used for discharging the service channel of one group of reverse MSS.
The mechanism that prior art only provides a kind of data path to set up and discharge, when traffic characteristics changes, in order to support this variation, just can only discharge corresponding data path on the ASN internal interface earlier by prior art, and then rebulid data path according to new traffic characteristics.Though this way is fine, but interacting message increases, and release that can't the designation data path whether set up process again be modification for same business, this business will be become the end of a business and the increase of another one new business by the BS of ASN inside or ASN-GW misunderstanding, the neutral gear that data path discharges and sets up occurs, the situation that service disconnection and datagram are lost can occur like this.
Summary of the invention
The invention provides when traffic characteristics changes, non-interrupting service is at the method and the network of ASN internal data way characteristic adjustment.Exist in the prior art in data path foundation and the release in order to solve, the neutral gear that data path discharges and sets up occurs, the problem that service disconnection and datagram are lost occurs.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
The initiator's who adjusts at traffic characteristics difference, we have proposed the processing method that traffic characteristics that traffic characteristics adjustment that the MSS side initiates and network side initiate is adjusted.As shown in Figure 2, have only service ASN-GW in the network, and do not have anchor ASN-GW, then have service ASN-GW and anchor ASN-GW in the network shown in Figure 3 simultaneously.In these processing methods, mainly be to describe anchor ASN-GW and serve the situation that ASN-GW is not together, situation promptly shown in Figure 3; And network shown in Figure 2 can be regarded the special case of network shown in Figure 3 as: under situation shown in Figure 2, the processing procedure between anchor ASN-GW and the service ASN-GW is all ignored.
Scheme one: adjust processing method for the traffic characteristics that the MSS side is initiated:
S11, MSS initiate dynamic service flow modify request messages (DSC-REQ) to BS, in the described dynamic service flow modify request messages (DSC-REQ), carry the information of the dynamic service flow that needs modification; BS will send dynamic service flow and revise reception message (DSC-RVD) to MSS, and expression BS has received request message.If BS determines to satisfy the modification request of MSS, then carry out S12, otherwise carry out S13;
S12, BS directly send response message (DSC-RSP) to MSS, point out that dynamic service flow modification message is rejected.MSS sends acknowledge message (DSC-ACK) and gives BS.
If the request of BS decision-making decision all modifications all is rejected, then whole process finishes.Otherwise BS revises acknowledge message (Data Path Modification Ack) notification service ASN-GW by data path.
If the request of service ASN-GW decision-making decision all modifications all is rejected, then whole process leaves it at that.Otherwise service ASN-GW revises acknowledge message (Data Path ModificationAck) notice anchor ASN-GW by data path, and whole process leaves it at that.
If S13 BS determines to satisfy the some or all of modification request of MSS, then initiate data path modify request messages (Data Path Modification Request) to service ASN-GW, the session identification that has comprised the Business Stream of needs modifications in this message, other information of parameter of need revising and the data path that may revise, these information the insides are clear and definite, and BS determines that satisfiable those paths are revised information requested.Be used for applying for revising descending (from service ASN-GW to the BS) data path between BS and the service ASN-GW, also comprise the information of the upstream data passage of needs modification simultaneously.
Whether S14, this service ASN-GW satisfy the modification request of this MSS according to the requirement decision of resource situation and request, if the requirement of all sessions is not satisfied, revising at the data path of giving BS so indicates all modifications request all to be rejected in the response message (Data Path Modification Response), carry out S12, otherwise continue.
S15, service ASN-GW select and can satisfy path and revise the session of request and respective via information and classified information (these information the insides have clearly comprised service ASN-GW and determined that satisfiable those paths revise solicited messages) and send on the anchor ASN-GW by data path modify request messages (Data Path ModificationRequest), be used for applying for revising descending (from anchor ASN-GW to the service ASN-GW) data path between service ASN-GW and the anchor ASN-GW, also comprise the information of the upstream data passage of needs modification simultaneously.
Whether anchor ASN-GW satisfies the modification request of this MSS according to the requirement of resource situation and request decision, if the requirement of all sessions is not satisfied, carries out S16 so; Otherwise anchor ASN-GW revises the session identification that indication can be accepted to revise in the response message (Data Path Modification Response) at the data path of giving service ASN-GW, information and result that the downlink data path is revised, and the information of up (from serving ASN-GW) data path to anchor ASN-GW, service ASN-GW receives receiving information according to anchor ASN-GW after this message, revise the session identification that indication can be accepted to revise in the response message (Data PathModification Response) at the data path of giving BS, information and result that the downlink data path is revised, and up (from BS to service ASN-GW) data path information, carry out S17.
The request of indication all modifications all is rejected in the response message (Data PathModification Response) if S16 revises at the data path of giving service ASN-GW, after service ASN-GW receives this message, the request of indication all modifications all is rejected in giving the data path modification response message (Data Path Modification Response) of BS, carries out S12.
S17, BS directly send response message (DSC-RSP) to MSS, point out that the dynamic service flow modification of correspondence is asked successfully.MSS sends acknowledge message (DSC-ACK) and gives BS.BS is according to the affirmation message of success/failure, the session service traffic identifier that success is confirmed is revised acknowledge message (Data PathModification Ack) notification service ASN-GW by data path, service ASN-GW revises acknowledge message (Data Path Modification Ack) notice anchor ASN-GW by data path, and whole process leaves it at that.
In the scheme one, BS, service ASN-GW and anchor ASN-GW have the ability of judging own resource, therefore behind the related news that network element sends on receiving, the ability of can carrying out is judged, the modification request that will meet own resource sends to next network element, will not meet the modification request refusal of self-ability.
Also can adopt another to judge the method for own resource in this scheme, promptly after BS receives the dynamic service flow modification solicited message of MSS transmission, by mutual with a resource management logical ne, obtain to agree the data path of request modification, and then to service ASN-GW and anchor ASN-GW transmission request, in this case, request all can be accepted, (just can be clear and definite when BS and resource management logical ne are mutual because not received, serve ASN-GW and anchor ASN-GW) and need not issue again.This scheme can be simplified handling process.
Embodiment 1:
Embodiment 1 is a specific implementation of scheme one, as shown in Figure 4, is the schematic flow sheet of the embodiment of the invention 1, and as seen from the figure, the present invention mainly may further comprise the steps:

S113, BS determine to satisfy the modification request of MSS, then initiate data path modify request messages (Data Path Modification Request) to service ASN-GW, the session identification that has comprised the Business Stream of needs modifications in this message, other information of the parameter that need revise and the data path that may revise.Be used for applying for revising descending (from service ASN-GW to the BS) data path between BS and the service ASN-GW, the present embodiment hypothesis is revised certain downlink data channel characteristic.
S114, service ASN-GW judge the modification request of satisfying this MSS according to the requirement of resource situation and request, (Data Path Modification Request) sends on the anchor ASN-GW by the data path modify request messages, is used for applying for revising descending (from anchor ASN-GW to the serving ASN-GW) data path between service ASN-GW and the anchor ASN-GW.
S115, anchor ASN-GW judge the modification request of satisfying this MSS according to the requirement of resource situation and request, data path modification result that anchor ASN-GW revises the session identification that indication can be accepted to revise in the response message (Data PathModification Response) at the data path of giving service ASN-GW, descending (from anchor ASN-GW to service ASN-GW).
S116, service ASN-GW receive receiving information according to anchor ASN-GW behind this response message, revise the session identification that indication can be accepted to revise in the response message (Data Path Modification Response) at the data path of giving BS, descending (from anchor ASN-GW to service ASN-GW) data path modification result.
S117, BS directly send response message (DSC-RSP) to MSS, point out that the dynamic service flow modification of correspondence is asked successfully.
S118, MSS send acknowledge message (DSC-ACK) and give BS, and notice BS adjusts successfully, in the BS side, revise content and come into force.
S119, BS revise acknowledge message (Data Path Modification Ack) notification service ASN-GW by data path, revise content and come into force on service ASN-GW.
S1110, service ASN-GW revise acknowledge message (Data Path ModificationAck) notice anchor ASN-GW by data path, revise content and come into force on anchor ASN-GW, and whole process leaves it at that.
The message primitive that relates in the said process is defined as:
Message primitive From->To Message content
Data Path Modification Request (data path is revised request) BS<->ASN GW； ASN-GW<->ASN GW The MSS sign, one group of { session identification, data path information is in order to discern the classified information of this Business Stream, session QoS information } that need revise
Data Path Modification Response (data path is revised response) ASN GW<->BS； ASN-GW<->ASN GW The MSS sign, one group of { session identification, data path information is in order to discern the classified information of this Business Stream, session QoS information } that need revise
Data Path Modification Ack (data path is revised and confirmed) BS<->ASNGW； ASN-GW<->ASN GW The MSS sign, { session identification } that a group acknowledge is revised

S21, anchor ASN-GW initiate data path modify request messages (Data Path ModificationRequest) and give service ASN-GW.If service ASN-GW determines to satisfy the modification request of anchor ASN-GW, then carry out S22, otherwise carry out S23.
S22, service ASN-GW directly send to anchor ASN-GW and indicate all modifications request to be rejected in the data path modification response message (DataPath Modification Response), point out that dynamic service flow modification message is rejected.Anchor ASN-GW sends data path and revises acknowledge message (Data PathModification Ack) to service ASN-GW.If the request of service ASN-GW decision-making decision all modifications all is rejected, then whole process finishes.Otherwise service ASN-GW revises acknowledge message (Data Path Modification Ack) notice BS by data path, if the request of BS decision-making decision all modifications all is rejected, then whole process leaves it at that.
S23, if service ASN-GW determines to satisfy the request of modification partly or completely of anchor ASN-GW, then initiate data path modify request messages (Data Path Modification Request) to BS, the session identification that has comprised the Business Stream of needs modifications in this message, other information that need parameter of revising and the data path that may revise, these information the inside has comprised service ASN-GW and has determined that satisfiable those paths revise information requested, also is used for applying for revising up (from BS to the serving ASN-GW) data path between BS and the service ASN-GW.
Whether S24, this BS satisfy the modification request of this service ASN-GW according to the requirement decision of resource situation and request, if the requirement of all sessions is not satisfied, revising at the data path of giving service ASN-GW so indicates all modifications request all to be rejected in the response message (Data Path Modification Response), carry out S22, otherwise continue, also comprise the information of the downlink data channel that needs are revised simultaneously.
S25, BS revise according to the needs of data path modify request messages (the Data Path ModificationRequest) the inside that receives and the sign of satisfiable each Business Stream of BS own resource is sent dynamic service flow modify request messages (DSC-REQ) to MSS.Can in a DSC-REQ message, carry the modification request of all Business Streams in principle.But according to the agreement regulation, a DSC-REQ message only can be revised a Business Stream at present, and the number of DSC-REQ is identical with the number of the Business Stream that needs to revise so.BS will receive one or more dynamic service flow and revise response message (DSC-RSP), with the success/failure of indication in the modification of MSS end dynamic service flow.After BS has received the response message of MSS for all Business Streams that need revise, revise indication in the response message (Data Path Modification Response) at the data path of giving service ASN-GW and can successfully accept the session identification revised, information and result that the upstream data path is revised, and the information of descending (from serving ASN-GW) data path to BS, service ASN-GW receives receiving information according to BS after this message, revise the session identification that indication can be accepted to revise in the response message (Data Path Modification Response) at the data path of giving anchor ASN-GW, information and result that the upstream data path is revised, and the information of descending (from anchor ASN-GW to service ASN-GW) data path.
S26, anchor ASN-GW revise acknowledge message (Data Path Modification Ack) notification service ASN-GW by data path, service ASN-GW revises acknowledge message (Data PathModification Ack) notice BS by data path, has confirmed the information of the Business Stream that can successfully revise at last in these message.Only receive after this message, the data path on this network element is revised just effective.BS sends the successful affirmation message (DSC-ACK) of dynamic service flow modification according to the sign of each Business Stream that the affirmation of data path modification acknowledge message (Data Path Modification Ack) the message the inside that receives is revised to MSS, revise response (DSC-RSP) message corresponding service stream for the application that other MSS send, then send the affirmation message (DSC-ACK) that dynamic service flow is revised failure to MSS.The total number of confirming of Business Stream must be identical with application modification response (DSC-RSP) message corresponding service stream number that MSS sends.
In principle, can in a DSC-ACK message, carry the modification of all Business Streams.If but air interface (interface between MSS and the BS) agreement regulation, a DSC-ACK message only can be determined a Business Stream, the number of DSC-ACK is identical with application modification response (DSC-RSP) message number that MSS sends so.
In the scheme two, BS, service ASN-GW have the ability of judging own resource, therefore behind the related news that network element sends on receiving, the ability of can carrying out is judged, the modification request that will meet own resource sends to next network element, will not meet the modification request refusal of self-ability.
Also can adopt another to judge the method for own resource in this scheme, promptly at anchor ASN-GW by mutual with a resource management logical ne, obtain to agree the data path of request modification, and then to service ASN-GW and BS transmission request, in this case, request all can be accepted, (just can be clear and definite when anchor ASN-GW and resource management logical ne are mutual because not received, serve ASN-GW and BS and need not issue) again.This scheme can be simplified handling process.
