Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The invention provides the implementation method that a kind of WiMAX of realization MCBCS service bearer is set up.Specifically comprise:
1) the MCBCS controller by after the service access authentication, returns relevant with business for information about as the specific strategy of QoS information, service bearer etc. the user.
The specific strategy of service bearer includes but not limited to: multicast bear (static multicast, dynamic multicast and stride autonomous territory multicast); Multicast/the unicast bearer of special line form; Unicast bearer etc.To each relevant bearing mode, carry necessary information respectively, the multicast address during multicast bear for example, perhaps MCBCS controller IP unicast address etc. during unicast bearer is to guarantee the smooth foundation of carrying.
2) to the foundation of the MCBCS service channel among the ASN, employing creates a mechanism to expand to existing data path and realizes.
Particularly, grappling SFA (AnchorSFA, the grappling service flow authorization) after the service access authentication is passed through, judge that the business that whether has had the user to ask on the AGW arrives: whether Business Stream/the path that comprises core network side arrives, and whether the data path of ASN side sets up (whether being assigned SFID).If also there is not SFID to exist, then be this traffic assignments SFID (traffic stream identifier), if there has been this business to arrive, then use existing SFID.
To multicast service carrier, if there be not professional arrival on the AGW, then need to carry out the adding of multicast, trigger the multicast tree of core net CSN side and set up work.
In AGW, also need the group business stream and the SFID of core-network side are mapped.
After determining SFID, carry out the work of setting up of path, undertaken by sending RESV to service SFA (ServingSFA, service business stream is authorized) to the ASN side.
For supporting the foundation of multicast path, need expand the parameter of RESV, include but not limited to: the shared attribute of data path, MCID, multicast address etc.
3) in the path setting process, ServingSFA after receiving RESV, the whether set of the shared attribute of judgment data path, if set, the resource that expression service SFA and riveting are decided between the SFA is reserved, and does not need reserved resource once more.
And whether the data path that determines BS exist, if exist then utilize existing data path; Otherwise, need carry out new data path and set up work, concrete is to set up request message by data path to set up.
Equally, expand data path setting request message, concrete expansion is with the RESV of front.
ServingSFA supports the data replication work to a plurality of DP (Data Path, data path), i.e. the correspondence of a plurality of DP of identical services and a SFID, thus save AnchorSFA to the resource between the ServingSFA;
4) business that DSx is initiated is set up flow process, after user's business application is obtained the authorization, can use similar/same path setting flow process of initiating with network side;
5) business that DSx is initiated also can be supported path request (DP_Req) message to carry out the work of setting up of path by BS, thereby can optimize path setting.
6) extended resources is reserved the relevant property parameters of setting up message with data path, comprises the multicast feature of MCID and/or multicast address, content ID, data path/SFID etc., supports the path setting of MCBCS business.
7) if BS also belongs to the MBS zone, then also need to realize each BS in the MBS zone synchronously, specifically need AGW and MBS zone manager to carry out alternately, obtain for information about after, set up path with other all BS in the zone, with the synchronized transmission in realization MBS zone.
Carry out at needs under the situation of MBS area synchronized, also need RESV is expanded, the field of expansion includes but not limited to: MCID (multicast connection identifier) etc.
Because Client-initiated MCBCS activation of service/application, can be with different approach, therefore, the carrying of correspondence foundation also has multiple mode, describes below by embodiment.
Embodiment one: the user sets up work by the carrying that IGMP Join carries out professional application/activation
Fig. 2 is the professional application/activation process figure of the embodiment of the invention one IGMP Join, and concrete performing step comprises:
400, the user passes through initial access authentication, and has set up initial service flow ISF/ pre-provisioned service flow PPSF, and the user can use other Networks like this;
401, the user selects interested MCBCS business, and the client-side program of MS at first can judge whether aloft this business exists in the interface by the MCBCS notice information of air interface, if exist, can directly change step 416; If business does not exist in eating dishes without rice or wine, even perhaps exist, also need to walk the access authentication flow process of standard, then carry out next step;
402, MS initiates multicast adding (IGMP Join) request message by client and carries business information in the message to AGW, as multicast address information;
403, AGW carries out the process that obtains the MCBCS controller address.
This step is an optional step, because AGW may obtain the MCBCS controller address by configuration, during perhaps business is in front carried out, has obtained relevant MCBCS controller address.Perhaps, can wait according to the multicast address information of carrying among the IGMP Join and obtain;
404, after the AGW/ authentication device receives that this IGMP joins request, send the service authentication request to the MCBCS controller, the user is carried out the access authentication authentication; In this service authentication request, include but not limited to information such as MS NAI;
405, the MCBCS controller carries out the access authentication authentication to the user, concrete can be user name/password, perhaps other authentication method in conjunction with the concrete characteristics of WiMAX network, and return authentication object information, if by authentication, then authentication result is not returned to the user by authentication device, process finishes; If pass through, in the authentication result information of then returning, also include but not limited to the information such as QoS demand of service bearer indication, business;
Described service bearer refers to the mode that the multicast broadcast service carrying is set up among the relevant CSN, specifically can include, but are not limited to following situation:
A) multicast mode (can be static, dynamic multicast, perhaps stride static state, the dynamic multicast in autonomous territory), core network operation multicast routing protocol, AGW directly uses multicast routing protocol to add.
B) the multicast mode of special line form, the MCBCS controller sends to each relevant AGW by special line with relevant business, and AGW still uses multicast routing protocol to add.
C) mode of unicast of special line form, the MCBCS controller sends to AGW by the form of clean culture with group business stream.Perhaps further, to the situation of roaming, can directly carry out the unicast service transmission.Use unicast bearer, also can be mapped and realize by group business stream with SFID and relevant core network.
Be designated as the multicast mode of multicast mode or special line form in this enforcement at the service bearer that returns.
406, AGW judges whether to have this business after receiving service bearer indication, and comprising: whether group business stream has arrived AGW, and the corresponding SFID that whether has been this traffic assignments.
To the group business stream of CSN side, AGW carries out the work of setting up of multicast tree according to different multicast bear modes.Concrete:
One), at static multicast, the perhaps multicast of special line form, multicast data flow has arrived AGW, does not therefore need the special work of setting up;
Two), to the dynamic multicast mode, the different qualities according to multicast protocol adds dynamically.Concrete, to the multicast protocol of sparse mode, AGW initiates adding work initiatively; And to the multicast protocol of dense mode, AGW realizes adding in the grafting/beta pruning process of multicast routing protocol.
If also do not distribute corresponding SFID, then need to distribute SFID; If distribute, then utilize existing SFID.
And further, the group business stream of SFID and core network side is mapped, after receiving relevant multicast data flow, the SFID path that relevant business is forwarded to correspondence gets on.
Further, if mobile terminal affiliated BS is in the MBS zone, then needs and to carry out on this multicast service all BS in the MBS zone synchronously.At this moment, AGW need communicate with the lock unit of MBS zone manager, obtain synchronizing information, MCID (multicast connection identifier) parameter for example, and the assignment information of relevant on-air radio resource etc., and, be forwarded to each BS and get on by setting up relevant path, to carry out synchronized transmission with corresponding service.Concrete path setting flow process can be the same with the follow-up method to the path setting between the BS.
407, the data path that AGW initiates among the ASN is set up process, and grappling SFA (AnchorSFA) sends resource reservation request message to service SFA;
For realizing support to the MCBCS business, need expand this message, to carry the professional relevant information of MCBCS, include but not limited to: multicast connection identifier and/or multicast address, to the resource reservation state information between the service SFA, or its combination.
On grappling SFA, need to expand the state information whether reserved of resource that is provided to service SFA.
Concrete, be sharing of the data path of realizing the ASN side, successfully set up under the situation of path first user of multicast service, should preserve the state information of having set up resource reservation among AGW/ grappling SFA and the service SFA.Need to use identical when professional once more etc. follow-up user, though transmit RESV between grappling SFA and service SFA, serving SFA does not need to do concrete resource reservation again.
408, owing to be MCBCS Business Stream (judging according to the resource reservation state information of having expanded), service SFA judges whether to exist the DP of service SFA to BS, if existence forwards step 413 to;
Concrete judgement, the state information that has established the DP of BS at service SFA according to whether realizes.This state information is the expansion of MCBCS business of the present invention to existing path setting mechanism.
409, service SFA sends expanded data path setting request message to BS, and request BS sets up data path;
Wherein the content of expanded data path setting request message expansion includes but not limited to: multicast connection identifier and/or multicast address, MCBCS service channel attribute, or its combination.
410-411, BS are according to business demand information, and the air interface resource situation, carry out resource allocation, perhaps according to the situation of MBS district management, use the resource information of having distributed, and carry out air resource and share out the work.Specifically comprise the data path of setting up between service SFA and the BS, and the aerial connection between BS and the MS;
412, BS is after setting up aerial connection, and to service SFA return data path setting response message, notification service SFA data path is set up.
Preserve service SFA among the service SFA and set up state to the data path of BS, and set up information according to the path that returns, set service SFA sets up state for setting up to the data path of BS; Service SFA also needs a plurality of DP of the same business that further may exist and this multicast broadcast service to be mapped, and is concrete, if there are a plurality of DP, service SFA need correspond to the information flow of same SFID on a plurality of DP.
In addition, need set up response message to this data path and expand, support that sharing characteristic is distinguished to the MCBCS business.
413, service SFA carries out resource reservation, sends out the resource reservation response message to grappling SFA, and the affirmation resource is reserved;
Grappling SFA preserves the resource reservation state information of grappling SFA to service SFA, and according to the resource of returning obligate information, set grappling SFA to the resource reservation state of service SFA for reserving (successfully reservation); If grappling SFA preserves the successful resource obligate information of grappling SFA to a plurality of service SFA, then grappling SFA need be transmitted to a plurality of service SFA with the multicast service stream information.
Need expand the resource reservation response message, make it support that sharing characteristic is distinguished to the MCBCS business.
414, service SFA sends expanded data path setting acknowledge message to BS, in this expanded data path setting acknowledge message, comprises the indication to the MCBCS business;
415, grappling SFA in the resource reservation acknowledge message of expansion, comprises the indication to the MCBCS business to the resource reservation acknowledge message that service SFA sends expansion;
So far, the data path among the ASN is set up and is finished;
In 406, describe,, then need repeating step 407-415, make each relevant BS obtain synchronously if there is the situation of MBS area synchronized;
416, optionally, the user obtains the key information of multicast service;
By after the authentication, step the 406 and 416 can be carried out simultaneously the user;
417, carry out business and transmit.
In the foregoing description, AGW also can replace to authentication device.
Embodiment two: the user directly carries out the path setting of service log-on by DSx
Fig. 3 carries out business by DSx to add flow chart.Concrete performing step comprises:
600, the user passes through initial access authentication, and has set up initial service flow ISF/ pre-provisioned service flow PPSF, and the user can use other Networks like this;
601, the user selects interested MCBCS business, and the MS client-side program at first can judge whether aloft this business exists in the interface by the MCBCS notice information of air interface:
If business exists, can directly change step 617;
If business does not aloft exist in the interface, even perhaps exist, also need to walk the access authentication flow process of standard, carry out next step;
602, MS sends out the professional application of DSx by client to BS, and (the DSA dynamic service increases, perhaps DSC dynamic service modification) message is carried out the adding of MCBCS business, the professional solicitation message of described DSx need be carried business information, as relevant business tine sign business information such as (MBS content ID), this content identification is used to the business of indicating the user to select;
603, BS forms the information of relevant user and professional application, and this information is sent to the AGW/ authentication device;
604, optionally, AGW/ carries out the process that obtains the MCBCS controller address;
Specifically be to determine, perhaps obtain the MCBCS controller address by other approach according to the business information of carrying in the professional application of the DSx authentication message;
One of optional reason of this step is that AGW may during perhaps business is in front carried out, obtain relevant MCBCS controller address by configuration MCBCS controller address;
605, the AGW/ authentication device sends the service authentication request to the MCBCS controller after receiving that relevant business joins request, and request is carried out the access authentication authentication to the user; Comprise in this service authentication solicited message: the user for information about, and business information;
606, the MCBCS controller carries out the access authentication authentication to the user, concrete can be user name/password, perhaps other authentication method in conjunction with the concrete characteristics of WiMAX network, and return authentication object information, if by authentication, then authentication result is not returned to the user by authentication device, process finishes; If authentication is passed through, in the authentication result information of then returning, also comprise the service bearer indication, the mode that multicast service carrier is set up among the promptly relevant CSN specifically can comprise:
A) multicast mode (can be static, dynamic multicast, perhaps stride static state, the dynamic multicast in autonomous territory), core network operation multicast routing protocol, AGW uses multicast routing protocol directly to add;
B) the multicast mode of special line form, the MCBCS controller sends to each relevant AGW by special line with relevant business, and AGW still uses multicast routing protocol to add;
C) mode of unicast of special line form, the MCBCS controller sends to AGW by the form of clean culture with group business stream.Perhaps further, to the situation of roaming, can directly carry out the unicast service transmission;
If CSN is the business of multicast bear, at a), b) two kinds of situations, the MCBCS controller returns multicast address, carries out next step.If the use unicast bearer is then used existing path setting mechanism, finish the work of setting up of service channel, flow process finishes.
607-616, step is with the step 406-415 of case study on implementation one;
617, optionally, the user obtains the key information of multicast service;
By after the authentication, step 607 and 617 can be carried out simultaneously the user.
618, set up the service bearer passage between MCBCS controller and the MS, carry out professional transmission.
Embodiment three: the user directly carries out the path setting (method two) of service log-on by DSx
IGMP Join and DSx transfer to the AGW/ authentication device and handle among the embodiment one, two, therefore, utilize existing mechanism, and data path is to be set up to the BS side by AGW.And if BS directly handles IGMP Join, then between BS and the AGW, need the operation multicast routing protocol, do not need to do relevant path setting, by generating corresponding multicast tree, directly, send to BS by multicast path with relevant business tine, rather than aforesaid multicast arrival AGW, carry out path setting by AGW again.
Fig. 4 carries out business by DSx to add another kind of embodiment flow chart.Be that with the main distinction of embodiment two user directly carries out the work of setting up of path by after the authentication by BS, its advantage is to make full use of the connection of having set up, thereby can save the time of path setting.Concrete performing step comprises:
