Description
Technical field
The present invention relates to communication technical field, particularly relate to and a kind ofly ensure method for ensuring service quality in marked net and system.
Background technology
The widely used TCP/IP in existing internet (Transmission ControlProtocol/Internet Protocol, transmission control protocol/internet protocol) IP address has dual-use function in agreement, both as the station location marker of communication terminal host network interface in network topology of network layer, again as the identify label of transport layer host network interface.But ICP/IP protocol does not consider the situation of host mobility at the beginning of design, when the situation of host mobility is more and more general, the semanteme overload defect of this IP address is day by day obvious.When the IP address of main frame changes, not only route changes, and the identify label of communication terminal main frame also changes, and routing overhead will be caused so more and more heavier, and the change of host identities mark also will cause application and the interruption be connected.
The object that identify label and position separation problem propose is the problems such as semanteme overload in order to solve IP address and routing overhead be serious, the dual-use function of IP address is separated, realizes mobility, many locals property, the dynamic code reassignment in IP address, alleviate the support of the problems such as exchanging visit in routing overhead and Next Generation Internet between heterogeneous networks region.
In prior art, the implementation method of router Network Based is that relating identity identifies one of solution be separated with position.
In prior art, proposed a kind of network identify label and position separation scheme, after to the network described by the program referred to as marked net, the basic thought of this scheme is: network is divided into Access Layer and core layer, correspondingly, network is divided into Access Network and backbone network.Mobile node in network has two kinds of identity type: User Identity (AccessIdentifier is called for short AID) and route location mark (Routing-LocationIdentifier is called for short RID).Each user in network has unique AID, and this AID remains constant in moving process; In data forwarding process, AID can only use at Access Layer, and RID can only use in core layer; Between user terminal during application layer communication, AID is used to identify opposite end.
The topological schematic diagram of above-mentioned network identify label and position split-frame as shown in Figure 1, as shown in Figure 1, in this network identify label and position split-frame, mainly comprise: wireless access network (RAN), IAD router (Access Gateway Router, be called for short AGR), broad sense gateway router (General Switch Router, be called for short GSR), mapping server (Identifier Mapping Server, be called for short IDMS), authentication center etc.Introduce respectively below:
AGR, primary responsibility provides access service for each mobile node (user terminal), for the user terminal of access distributes RID, and transmits in backbone network after the data message of user terminal being carried out mark encapsulation.
AGR is when receiving the data message that user terminal is sent, inquire about the AID-RID mapping table in local cache (CACHE) according to destination address in data message (i.e. the AID of Correspondent Node): if find corresponding AID-RID map entry, then the RID of the communication terminal found is encapsulated in header and is sent to backbone network and carries out forward process; If do not find corresponding AID-RID map entry, then by data message forwarding to backbone network, and the flow process of inquiry (Correspondent Node) AID-RID map information is initiated to IDMS, and AID-RID mapping IDMS being returned correspondence is kept at this locality, inquires about when forwarding in order to subsequent packet.Or, AGR is not when finding corresponding AID-RID map entry, also can select not by data message forwarding to backbone network, but the flow process of inquiry (Correspondent Node) AID-RID map information is initiated to IDMS, return after corresponding AID-RID maps until IDMS, the RID of the communication terminal found is encapsulated in header and is sent to backbone network and carries out forward process.
AGR, when receiving the data message mailing to user terminal, carries out decapsulation process to data message, peels off the heading comprising RID newly-increased in data message, mails to terminal.
The major function of GSR carries out routing and forwarding data packets according to the route location mark RID in data message.
The mapping relations of User Identity and station location marker in IDMS primary responsibility maintaining network, and provide inquiry service to IAD router and other mapping server.
Authentication center, authentication center is responsible for the information such as recording user classification, user's grade of service, carries out legitimacy authentication and authorization when user accesses to user.Bi-directional authentification between authentication center's network enabled and user.
Wireless access network, is responsible for providing two layers of link also between maintenance customer's terminal to IAD router-A GR; RRM is responsible in cellular mobile network application scenarios.
Under this framework shown in Fig. 1, network can be divided into Access Network and backbone network.Access Network is positioned at the edge of backbone network, and be responsible for the access of all user terminals, in Access Network RAN part, all user terminals all use AID to carry out addressing.Backbone network is responsible for the route by different Access Network access user terminal.Access Network and backbone network do not have overlapping on topological relation.Between communication host, application layer uses AID to identify opposite end, and the communication between user terminal only need use the AID of opposite end to carry out.
IAD router is positioned at the separation of backbone network and Access Network, as the interface of Access Network and backbone network, is responsible for that user terminal provides access service, maintenance customer connects, forward user data etc.All communications of user terminal are all undertaken forwarding and managing by the IAD router of place access network.Between user terminal within the scope of same IAD router services, data message is directly transmitted to opposite end.Between user terminal within the scope of different IAD router services, the forwarding of data message is as follows: user terminal is when sending data message, and corresponding IAD router carries RID information (this RID and AID is corresponding) in the data message forwarded; Corresponding, user terminal is when receiving data message, and IAD router carries out contrary operation, namely peels off RID information and by data message forwarding to user terminal.Save the identity position identity map relation that all user terminals accessed in network distribute in mapping server, and carry out identified relationships parsing with IAD router by Signalling exchange.
As shown in Figure 2, S1/D1 is the interface of user terminal and IAD router-A GR to the relevant interface of the network architecture of above-mentioned network identify label and position split-frame, and S1 is used for the signaling of user access administration, and D1 is data retransmission interface; Handover management signaling when S2 is used for switching between AGR, D2 is used for data retransmission when switching between AGR; D3 is the data retransmission interface between AGR and GSR, and S4/S5/S6 is the signaling interface for inquiring about and safeguard AID-RID mapping relations, and D4m is the data retransmission interface between AGR and IDMS.Wherein, when vistedIDMS (visited place IDMS) and Home IDMS (ownership place IDMS) is without direct connection relation, Broke IDMS (relaying IDMS) forwards the signaling between visted IDMS and Home IDMS.
Along with flourishing the sending out of telecommunications industry is opened, the competition between each operator also increasingly sharpens, and the competition especially around terminal, business, service quality expansion is more and more fiery.And service quality is becoming the key element that operator enhances competitiveness.Along with going deep into of operator, the type of user terminal (mobile node) is also tending towards complicated, and the intension of subscriber terminal service is also widened gradually.Therefore, the service quality of different stage is provided for different user terminals, reaches differentiated service, lean operation, become the important means improving operator ability.But, in existing marked net technology, not yet consider the solution realizing type of user terminal differentiated service quality.

Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Service quality (Quality of Service, QoS) is operator network, improves the major issue that service needs to solve.At present, for the service quality that different users provides different stage, reaching differentiated service, lean operation, is the important means improving operator's own operations ability and self competitiveness.But, in current marked net technology, not yet consider the solution of service quality.
The technical problem to be solved in the present invention is: the service quality providing differentiation to the mobile node (user or user terminal) in marked net, improves the operation ability of operator in marked net.For solving the technical problem existed at present, the present invention, in the technical foundation be separated based on marked net identity, position, proposes a kind of QoS grade distinguishing mobile node, and provides the method for corresponding service quality according to the QoS grade of mobile node.
Central scope of the present invention is: the MN in access marked net, according to the CAMEL-Subscription-Information of mobile node MN, is divided into different COS by operator, and in advance for the MN of different COS arranges corresponding service quality rating.When MN initiates Business Stream, IAD router-A GR selects corresponding routing mode to carry out the forwarding of data message according to the service quality rating of MN.Specifically, operator is according to the CAMEL-Subscription-Information of MN, for MN arranges different service quality ratings, because MN needs to access marked net by IAD server (AGR), and multiple different MN also may access marked net, therefore, in order to realize the differentiated service of MN by same AGR, operator also needs to preset multiple different routing mode to same AGR, thus in backbone network, mark off the logic plane of several different QoS grade.Wherein each routing mode is corresponding with a kind of service quality rating of MN.That is, operator need to same AGR preset several to access AGR with the MN of different QoS grade time corresponding routing mode.When the MN of different service quality grade accesses marked net by same AGR, AGR can according to the service quality rating of this MN, and select corresponding routing mode, the data message sent by MN forwards.
MN is being implemented in the embodiment of differentiated service, in order to ensure the accuracy of each MN service quality, when accessing the MN attach to network in marked net, namely during MN attachment, the each MN docked in inlet identity net is also needed to carry out certification, the object of certification mainly judges that whether the mobile node accessing marked net is legal, and authorizes legal mobile node.Verification process is specifically: the IAD router-A GR belonging to MN sends the authentication request to this MN to authentication center, and authentication center receives this authentication request information and carries out certification.Wherein, the authentication request information of MN can be user name, the password of MN, and international mobile subscriber identity IMSI.If this MN is by the certification of authentication center, authentication authorization and accounting success, the so mandate at this MN then access authentication center, can carry out the operation initiating Business Stream.If authentification failure, so, this MN then can not carry out the operation initiating Business Stream.
In one embodiment, the information of the service quality rating of each MN preset is stored in authentication center, when IAD router-A GR initiates the authentication request to certain MN to authentication center, authentication center carries out certification to this MN; If authentication success, affiliated IAD router-A GR when service quality rating information corresponding for this MN being stored in self also sends to this MN to access marked net by authentication center.
In fact, if the information of the service quality rating of MN is stored in authentication center, so when MN initiates Business Stream, AGR also needs to send service quality rating information corresponding to this MN to mapping server and inquire about the solicited message of this MN routing mode.Wherein, in mapping server, store the routing mode of all mobile nodes in network, the service quality rating information that now mapping server is corresponding according to this MN received, select routing mode corresponding to this MN and return to IAD router-A GR.The data message that MN sends according to the routing mode of this MN returned from mapping server by AGR forwards.AGR is according to the information of the routing mode of this MN, and when judging that the Correspondent Node that this MN is corresponding and this MN belong to same AGR, so data message is then forwarded directly to the AGR belonging to Correspondent Node of this MN by this AGR; If AGR judges that the Correspondent Node corresponding to this MN belongs to different AGR from this MN, so this AGR then by according to the routing mode of this MN received by data message forwarding to backbone network.When AGR obtains the routing mode of this MN from mapping server, the routing mode of this MN is also stored in own cache by AGR, when this MN is needed to send by follow-up data message, AGR then inquires the routing mode of this MN from own cache, and carries out the forwarding of data message according to this routing mode.That is, for the forwarding situation of the data message of the same Business Stream of MN, AGR only can send the request of the routing mode of this MN of one query to mapping server.
In fact, the information of the service quality rating of each MN preset is stored in authentication center, when IAD router-A GR initiates the authentication request to certain MN to authentication center, authentication center also carries out certification to the authentication request of this MN; If authentication success, service quality rating information corresponding for this MN also can be sent to mapping server by authentication center.Now, when this MN initiates Business Stream, send the solicited message of this MN routing mode of inquiry to mapping server, but now AGR does not then need service quality rating information corresponding for this MN to send to mapping server.The solicited message of this MN routing mode of inquiry that mapping server is sent according to AGR, and combine service quality rating information corresponding to this MN of obtaining from authentication center, select the routing mode that this MN is corresponding, and this routing mode is returned to AGR.The data message that MN need send, according to the routing mode of this MN received, forwards by AGR.Certainly, AGR also stores the routing mode of this MN obtained from mapping server, when the same Business Stream of this MN also has follow-up data message to send, AGR then inquires the routing mode of this MN from own cache, and carries out the forwarding of data message according to this routing mode.
It should be noted that, the service quality rating information of the mobile node preset is not only limited to and is stored in authentication center, in one embodiment, also the service quality rating information of default mobile node directly can be stored in mapping server.Now, when MN adheres to, authentication center then only needs to carry out certification to the authentication request of certain MN that AGR sends, then no longer have the mutual process of data message.If authentication success, this MN then can initiate Business Stream.Similarly, when MN initiates Business Stream, AGR sends the solicited message of this MN routing mode of inquiry to mapping server, and the service quality rating information that this MN that mapping server stores according to self is corresponding, selects routing mode corresponding to this MN and return to AGR.The data message that MN need send, according to the routing mode of this MN received, forwards by AGR.Similarly, certainly, AGR also stores the routing mode of this MN obtained from mapping server, when the same Business Stream of this MN also has subsequent packet to send, AGR then inquires the routing mode of this MN from own cache, and carries out the forwarding of data message according to this routing mode.
In fact, when the AGR belonging to MN receives the data message of certain Business Stream that MN initiates, be not the routing mode at once just sending this MN of inquiry to mapping server.First MN can check the routing mode whether having this this Business Stream of MN in own cache, if have, the then unnecessary request sending the routing mode of this this Business Stream of MN of inquiry again to mapping server, but the forwarding of data message is directly carried out according to the routing mode of this MN stored in own cache.Adopt this kind of mode, reduce the overhead that some AGR are unnecessary to a certain extent.
In practice process, for the Business Stream of first data message forwarding that MN initiates, AGR can also first by this data message forwarding in backbone network, and then initiate the request of routing mode of this MN of inquiry to mapping server.The information of the routing mode of this MN that AGR returns according to mapping server place, and be kept in own cache, when the same business that this MN initiates has follow-up data message to need to send, AGR carries out the forwarding of data message according to the routing mode of this MN stored in own cache.
In fact, when in marked net, the data message of AGR to a certain Business Stream of certain mobile node forwards, routing mode has a variety of.In one embodiment, according to the AGR in marked net, according to route location mark (RID), outer envelope is done to the data message of mobile node, so in backbone network, be all the feature of carrying out data message route according to route location mark (RID), routing mode be specifically set to the mapping relations of User Identity (AID)-route location mark (RID).AGR, according to the mapping relations of AID-RID, selects corresponding mapping relations to be forwarded by data message.
As shown in Figure 3, for the process chart in an embodiment of the present invention during MN attachment, certainly, before MN attachment, preset the routing mode during mobile node access IAD router of the service quality rating of mobile node and different service quality grade.Below according to Fig. 3, for PPP over Ethernet access, do further more detailed description to during MN attachment of the present invention, idiographic flow is as follows:
301, pppoe session is set up between MN and AGR; In conversation procedure, (authentication information can be user name, password the authentication information of MN to be sent to AGR; Also can be international mobile subscriber identity IMSI);
302, AGR process pppoe session message, therefrom extracts the authentication information of MN;
303, AGR is to the authentication request of authentication center's initiation to MN;
304, the authentication request information of authentication center to MN carries out certification;
305, the authentication request of authentication center to AGR is replied, return authentication result (by or do not pass through), if pass through, then the QoS grade of MN is returned to AGR;
306, the QoS grade of MN is sent to mapping server by authentication center;
About the QoS grade of MN, authentication center can send to AGR, also can send to mapping server, and when reality uses, two schemes is chosen any one kind of them.
As shown in Figure 4, the mobile node for an embodiment of the present invention initiates handling process schematic diagram during Business Stream, and the concrete handling process when MN initiates Business Stream is as follows:
401, when MN initiates a certain item business, the generation of trigger business stream;
402, Business Stream is sent to AGR by MN;
403, AGR initiates the inquiry of AID-RID mapping relations to mapping server, when supposing that MN adheres to, the QoS grade of MN issues and gives AGR by authentication center, so now, AGR, when sending mapping relations inquiry to mapping server, also needs the QoS grade of MN to send to mapping server;
404, mapping server is that MN chooses suitable RID according to the QoS grade of MN;
405, the mapping relations of AID and RID are returned to AGR by mapping server; AGR encapsulates according to the message of mapping relations to Business Stream and is forwarded to backbone network.
Application the present invention, in marked net, presets the QoS grade of each MN and presets routing mode corresponding to the QoS grade of several from different MN for each AGR, thus marked net being marked off the logic plane of several different QoS grade; Different QoS is had to ensure between each logic plane, therefore, be that the Business Stream that MN initiates chooses suitable routing mode according to the QoS grade of MN, just can realize the traffic flow assignment of the MN of different QoS grade to different logic planes, reach the effect of different QoS grade guarantees.
Meanwhile, present invention also offers a kind of system ensureing mobile node service quality in marked net, it is characterized in that, comprise presetting module and routing selecting module;
Described presetting module is used for presetting routing mode corresponding to the IAD router belonging to mobile node of the service quality rating of mobile node and different service quality grade;
Described routing selecting module is used for, when described mobile node initiates Business Stream, selecting corresponding routing mode to carry out transfer of data according to the service quality rating of described mobile node.
Apply a kind of method and system ensureing mobile node service quality in marked net provided by the invention, operator can according to the CAMEL-Subscription-Information of mobile node, for mobile node arranges different service quality ratings; Corresponding mapping relations when correspondingly also presetting the mobile node access IAD router of different service quality grade, thus making when mobile node is when initiating Business Stream, the IAD router belonging to mobile node can select corresponding road mapping relations to carry out data retransmission according to the service quality rating of mobile node.Like this, operator can provide the service quality of different brackets for different mobile nodes, reach differentiated service, lean operation, improves operation ability and the competitiveness of operator self.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
