Description
Technical field
The present invention relates to multicast broadcast service (MBS), or rather the entity of the method for deletion/modification MBS business and realization deletion/modification MBS business in communication system.
Background technology
IEEE802.16 is (the Institute of Electrical andElectronies Engineers of Institute of Electrical and Electronics Engineers, be called for short " IEEE ") in promulgation in December calendar year 2001, the standard that provides last kilometer WiMAX to insert at metropolitan area network is provided.
Micro-wave access to global intercommunication (Worldwide Interoperability for MicrowaveAccess, be called for short " WiMAX ") be to wireless MAN access technology according to present industry based on the IEEE802.16 series standard, its elementary object provides a kind of under some multivendor environment to multiple spot of metropolitan area network, effectively the broadband wireless access means of interoperability.
Specifically, 802.16 series standards have been stipulated the air interface part protocol layer of WiMAX system, mainly comprise physical layer (PHY), and medium access control (Medium Access Control is called for short " MAC ") layer.Wherein, the PHY layer is finished physically to operations such as the modulation of signal and encoding and decoding, and the MAC layer is mainly finished the medium access control function of WiMAX system.
Fig. 1 illustrates the end-to-end reference model of WiMAX.Wherein the R1 interface is a wireless air interface, is mainly defined by IEEE802.16d/e.All the other interfaces are wireline interface.
As can be seen, WiMAX mainly comprises travelling carriage (Mobile Station, be called for short " MS ")/subscriber station (Subscribe Station, abbreviation " SS "), access service network (Access ServiceNetwork, be called for short " ASN ") and connectivity serving network (Connectivity ServiceNetwork is called for short " CSN ").
ASN is defined as the network function set that the wireless access service is provided for the WiMAX user terminal, and ASN has comprised BS and ASN gateway (ASN GateWay is called for short " ASN-GW ") network element, and an ASN may be shared by a plurality of CSN.
The major function of ASN comprises the function of BS and the function of ASN-GW.Wherein, the function of BS has: provide that BS is connected with the L2 of subscriber station SS/MS, the compression and the encryption of RRM, measurement and the power control and the data of eating dishes without rice or wine.The function of ASN-GW has: for SS/MS authentication function provides agency (proxy) function; Support the network of NSP (Internet Service Provider) to find and selection; For SS provides relaying (Relay) function of L3 information, as IP address assignment.
CSN is defined as to the WiMAX user terminal IP is provided Connection Service.CSN mainly provides the IP address assignment of following function: SS/MS, Internet inserts, checking, mandate, charging protocol (Authentication, Authorization, Account, be called for short " AAA ") agency (proxy) or service (server), authorization control based on the user, ASN is to the tunnel of CSN, WiMAX user's charging and the clearing between the operator, tunnel under the roaming condition between the CSN, switching between the ASN and various WiMAX service (as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business).
MS/SS is (moving) terminal, and the user uses this terminal to insert the WiMAX network.
More than WiMAX and network architecture thereof are illustrated, below to Multimedia Broadcast Multicast Service (Multicast; Broadcast Service is called for short " MBS ") simply introduce.
Fast development along with Internet (internet), people no longer content just to phone and messaging service to the demand of mobile communication, a large amount of multimedia services emerge, the some of them applied business requires a plurality of users can receive identical data simultaneously, as video request program, television broadcasting, video conference, online education, interactive game etc.On cable network, can adopt internetworking agreement (InternetProtocol at present, abbreviation " IP ") multicast and broadcast technology realize, but these business are transplanted on the mobile network, compare with general data, characteristics such as data volume is big because these business have, longer duration, delay sensitive, and mobile network has particular network structure, functional entity and wave point etc., and existing IP multicast and broadcast technology can not be directly applied for mobile network.
In order to effectively utilize mobile network resource, WiMAX has defined the MBS business, and the MBS business is that the point-to-multipoint service of a data source to a plurality of users send data is provided in the mobile network, realizes that Internet resources are shared, improve utilization rate of network resource, especially air interface resource.The MBS of WiMAX definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of following mobile data development undoubtedly.
In the MBS business, some service flow can be carried to the broadcast or multicast information of a plurality of terminals, and these service flow comprise service quality (Quality of Service is called for short " QoS ") parameter, in order to improve service security, can also encrypt it with data encryption key.
Two kinds of access modules of MBS business support based on the WiMAX network: single base station is inserted and many base stations are inserted.Under the access module of many base stations, a MBS district (MBS Zone, adopt sign with MBS_zoneIdentifier) in all base stations send the content of same MBS Business Stream with identical multicast connection identifier (CID (MulticastCID) and MBS group Security Association (MBS GSA), having registered the terminal that MBS serves can be by a plurality of base stations reception MBS content in the MBS district.And the terminal that is in Idle (free time) pattern need not rebuild connection when MBS district interior span BS moves, can impregnable reception MBS business, realize the seamless switching of MBS business.It is a kind of special case that MBS are inserted in many base stations that MBS is inserted in single base station, and multicast district scope is defined as in the base station, and all users of this multicast service of reception use same multicast connection identifier (CID in sub-district.
In the WiMAX network, by traffic stream identifier (Service Flow Identifier, abbreviation " SFID ") identifies different one-way traffic flows, identify different connections by CID, all Business Streams are being eated dishes without rice or wine by media interviews control (Medium Access Control, being called for short " MAC ") connection of layer transmits, by shining upon, Business Stream transmitted in the connection of correspondence between the SFID of Business Stream and the CID that the MAC layer is connected.Based on WiMAX network MBS business on the basis of above-mentioned sign, also identifying multicast specially by multicast connection identifier (Multicast CID) connects, identify a multicast content by multicast content sign (MBS Contents ID), the protocol Data Unit of transmission on Mulicast CID (Protocol Data Unit is called for short " PDU ") can comprise one or more MBS contents.
In the WiMAX network, for unicast service, the scope of application of SFID only limits in the ASN, in the cross neutralization CSN of ASN and CSN, uses traffic identifier (FID:Flow ID) to come identification service stream.The two shines upon on anchor point service flow authorization person (Service Flow Authorization is called for short " SFA ").The service flow authorization person is responsible for authorizing to corresponding business stream, and this functive is present among the ASN.
In cordless communication network, in order to guarantee the wireless multicast communication security, the multicast packet of eating dishes without rice or wine to transmit is all encrypted with multicast key, only allows the user of signatory this multicast service could receive this multicast service to guarantee network.With the wireless communication system based on the realization of 802.16 agreements is example, and its encryption of carrying out multicast packet need be adopted three keys, is respectively: MAK (MBS authorization key), MGTEK (MBS group key encryption key), MTK (MBS business cipher key).In IEEE 802.16-2005 agreement, the generation of MAK and transmission are defined by application layer, MGTEK passes to terminal after encrypting with KEK (key-encrypting key) or GKEK (group key encryption key), MAK and MGTEK calculate MTK through certain algorithm (as the Dot16KDF algorithm), and MTK is directly used in the encryption and decryption multicast packet.
For using grand diversity to strengthen receptivity, in IEEE802.16, introduced MBS mapping (MBS-MAP) message, this message is transmitted in MBS district (MBS ZONE), is used for notifying the physical channel resources of distributing for concrete Multicast CID at given MBSZONE.MBS-MAP message further specifies each business datum piece to go up the position of employed modulation coding mode (DIUC), power bias (Boosting), next MBS traffic frame and next MBS-MAP message frame in the physical channel resources (Burst) of appointment with MBS_DATA_IE.Therefore, as long as can correctly detect MBS-MAP message, terminal just can connect pairing physical channel resources according to the multicast that this message obtains desired reception, further obtain employed modulation coding mode, power bias etc. on this physical channel resources, comprise the position of the MBS frame of this multicast connection in further definite next frame, thereby carry out the Data Receiving that normal multicast connects.
Below introduced professional relevant network element and function thereof with MBS, as shown in Figure 2:
(1) content supplier: i.e. multicast broadcast service supplier as the supplier of MBS program, is used to the MBS business tine that provides concrete;
(2) MBS server: be used to control the MBS program that content supplier is provided and be transmitted to corresponding M BS agency;

Embodiment
Core of the present invention is, the invention discloses the process of deletion/modification MBS business, makes after the MBS service ending or network side when wanting to change the configuration of MBS business, the related resource that network side can discharge or be revised as the professional storage of this MBS and reserve.The counterpart terminal side, after the MBS service ending, or terminal do not want to receive MBS when professional, and the deletion end side makes terminal withdraw from this MBS business for the related resource of the professional storage of this MBS; After perhaps network side is revised the MBS business, with the MBS business configuration notice terminal that changes.
Deletion/the modification of MBS business of the present invention can be divided into following two parts: the operation of method of deletion/modification MBS business in the communication system (process of deletion/modification network side MBS business) and corresponding end side (comprises that terminal withdraws from the MBS business, after network side modification MBS business, with the MBS business configuration notice terminal that changes).And the deletion/modification of MBS business of the present invention mainly is based on Wimax (micro-wave access to global intercommunication) network.Below be that example illustrates how to realize above-mentioned three parts respectively just with the Wimax network.
See also Fig. 3, it is the flow chart of the method for deletion/modification multicast broadcast service in the communication system.May further comprise the steps:
S110: the professional deletion/modification request of the multicast and broadcast MBS that the receiving terminal receiving end/sending end sends;
S120: the respective resources of the described MBS business of receiving terminal release/modification;
S130: receiving terminal returns the professional deletion/modification response of MBS.
When transmitting terminal sends MBS business deletion/modification request, carry MBS service identification usually in order to sign MBS business.Described MBS service identification is one of them or its combination in any in MBS content identification (MBS Contents ID), multicast ip address/port numbers, traffic identifier (Flow ID), traffic stream identifier (SFID), multicast connection identifier (Multicast CID), authorization token (authorization token), the MBS district sign (MBS ZoneIdentifier).If the MBS server is merged into an IP bag with a plurality of IP multicast data flows, this IP bag finally is to be carried on when transmitting on the Multicast CID, in order to what identify each IP multicast data flow is MBS Contents ID, the IP that identifies after this merging with Flow ID in the CSN territory and in the mutual process of ASN and CSN wraps, and identifies with SFID in the ASN territory.The combination of IP multicast data flow also can be finished by MBS agency, and only identify this IP bag after merging with SFID and get final product this moment.Described authorization token is the sign that application layer is given certain MBS traffic assignments, can identify professional and its qos parameter of a MBS, is used to authorize the application layer Business Stream to create or the QoS of one or more IP streams that modification process generates.That is to say that transmitting terminal sends professional deletion/modifications of MBS when asking, and need carry a MBS service identification usually, be used to show this operate at the MBS business.
Certainly, when transmitting terminal sends MBS business deletion/modification request, also can not carry the MBS service identification.Such as, when transmitting terminal and receiving terminal are made an appointment when not carrying the MBS service identification, be to operate all MBS service identifications of receiving terminal, for another example, receiving terminal only has a MBS business, transmitting terminal send to the MBS business delete/during retouching operation, only operate at this MBS business, at this moment, transmitting terminal sends the professional deletion/modification request of the MBS that does not carry the MBS service identification, is defaulted as the MBS operation is deleted/revised to a certain specific MBS business of receiving terminal or all MBS business.
MBS business modification/removal request can be carried with a message, also can be respectively two independent message and carry.If the former need be provided with a sign and show that described message is retouching operation or deletion action at present.
Among the step S110, if revise the MBS business, the then described resource that needs to revise is a service quality QoS parameter, MBS content identification MBS Contents ID, physical layer parameter, MBS district sign MBSZone ID, MBS group Security Association MBS GSA ID, traffic stream identifier SFID, multicast connection identifier Multicast CID, traffic identifier FID, MBS safe key and contextual one of them or its combination in any.
In step S120, receiving terminal is according to the professional deletion/modification request of the MBS that receives, corresponding processing MBS business.Such as, after receiving terminal received deletion MBS service request, the deletion local terminal was the related resource of the professional storage of this MBS.Related resource comprises two aspects, the carrying (as the tunnel between the data channel in the ASN and/or ASN and the MBS server) that the aspect is tunnel or other form, the 2nd, in MBS server and the ASN traffic flow parameters, physical layer parameter and the security of multicast key of the professional storage of this MBS.Wherein Cheng Zai deletion can optionally be carried out according to the granularity in tunnel.For example, when the data channel in the ASN was granularity with every base station, this moment, the deletion of a MBS business did not need to delete corresponding data channel.If when the data channel in the ASN was granularity with every Business Stream, then the deletion of this MBS business also can comprise the deletion of this data channel.When receiving modification MBS service request, according to the modification parameter modification local terminal corresponding parameters of carrying in this MBS service request.
That is to say, transmitting terminal and receiving terminal are professional storage of this MBS and reserved resource below the deletion/modification in the professional deletion/modification request process of MBS: the data channel in the ASN, and/or the tunnel between ASN and the MBS server, and/or in MBS server and the ASN traffic flow parameters, physical layer parameter and/or the security of multicast key of the professional storage of this MBS.
In step S130, receiving terminal returns the professional deletion/modification request of MBS response.This message is carried MBS service identification, the professional deletion/modification result of MBS.When not carrying the MBS service identification when professional deletion/modifications of MBS that sends when transmitting terminal asked, can not carry the MBS service identification equally during response message that receiving terminal returns yet, certain, for the sake of clarity, also can carry the MBS service identification.Above-mentioned processing all should drop in the scope of protection of the invention.
When the MBS server was positioned at connectivity serving network CSN territory, transmitting terminal and receiving terminal were respectively MBS server and MBS agency, perhaps are respectively MBS agency and base station; When the MBS server was positioned at access service network ASN territory, transmitting terminal and receiving terminal were respectively MBS server and base station.The trigger condition of deletion MBS business is this MBS service ending, and the trigger condition of revising the MBS business need be revised the related resource configuration of this MBS business for the MBS server.
Need to prove that the MBS business that needs to handle is not limited only to some BS, when being many base stations access module, all BS in a MBS district send the professional deletion/modification request of MBS respectively.
Below just lift several examples and illustrate how to revise/delete network side MBS business procedure.
