Description
Technical field
The invention belongs to moving communicating field, relate in particular to the method that activates in the multimedia broadcast/group broadcast service.
Background technology
Multicast and broadcasting are a kind of technology that transmits data message from a data source to a plurality of targets.Along with the fast development of Internet, a large amount of multimedia services emerge, and the some of them applied business requires a plurality of users can receive identical data, for example video request program, television broadcasting, video conference, online education or interactive game etc. simultaneously.Compare with general data, these multimedia services have characteristics such as data volume is big, longer duration, delay sensitive.Because the mobile network has particular network structure, functional entity and wave point, and is different with wired IP network, therefore present IP multicast service only is applicable to wired IP network, is not suitable for the mobile network.
In order to effectively utilize mobile network resource, third generation partnership project (Third GenerationPartnership Projects, 3GPP) multimedia broadcast/group broadcast service (MultimediaBroadcast/Multicast Service has been proposed, MBMS), promptly in the mobile network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, and improve utilization rate of network resource, especially air interface resource.The MBMS of 3GPP 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.
The network reference model of MBMS as shown in Figure 1, the edge of MBMS bearer service is Gmb, Gi reference point, be broadcast multicast service center (BM-SC) and gateway GPRS (GPRS) support node (Gateway GPRS Support Node, GGSN) interface between, the Gmb interface provides the chain of command function, and the Gi interface provides the user plane bearer function.
BM-SC is the inlet of content provider/multicast and broadcast content source, be used for authorizing and initiating the MBMS bearer service at mobile network, and plan transmits the MBMS content to schedule.Its function comprises third party content supplier authentication, mandate and charging; MBMS transmission relevant parameter is provided, for example service quality (Quality of Service, QoS), multicast and broadcast zone, initiation and termination MBMS transfer resource; Receive and transmit the MBMS content from external data source, arrange the MBMS session to transmit and inform user, session re-transmission etc.; Service statement comprises media description, conversation description such as multicast service identifier, address, delivery time etc.Content provider/multicast and broadcast content source can be passed through Packet Data Network, and (Packet DataNetwork PDN), provides content as internet to BM-SC.
GGSN is as the IP multicast service node of MBMS data, request according to BM-SC is broadcasting or multicast transmission foundation or release and Serving GPRS Support Node (Serving GPRS Supporting Node, SGSN) the MBMS carrying between, receive IP broadcast/multicast content from BM-SC or other data source, and (GPRS Tunneling Protocol, GTP) tunnel sends relevant SGSN to pass through GPRS Tunnel Protocol.
SGSN carries out network control to the user, support MBMS recipient moving between SGSN, request foundation or the carrying of the MBMS between release and the GGSN according to GGSN, send the broadcast/group broadcast data to Radio Access Network (Radio Access Network, RAN), as the Universal Terrestrial Radio Access Network road (Universal Terrestrial Radio Access Network, UTRAN), GSM EDGE Radio Access Network (GSM/EDGE Radio Access Network, GERAN).(Home Location Register HLR) obtains user profile to SGSN by attaching position register.
RAN is according to request foundation or the carrying of the MBMS between release and the SGSN of SGSN, select shared channel or dedicated channel to transmit the MBMS business in predetermined broadcasting/packet service zone, support core net to initiate and stop MBMS to transmit, support the MBMS recipient at radio network controller (Radio NetworkController, moving RNC), support MBMS transmission service statement, paging information, MBMS concurrent service, for example receive the MBMS video content and carry out audio call and messaging service simultaneously.
Subscriber equipment (User Equipment; UE) support activation MBMS business; content is encrypted and MBMS safety related functions such as consistency protection, receive MBMS service statement, paging information or support synchronous service and according to the MBMS session identification decision whether ignore the MBMS session.
In the network reference model of above-mentioned MBMS, Gn/Gp represents the interface between SGSN and the GGSN, Gi represent interface between BM-SC and the GGSN and interface protocol be Internet group management protocol of the multicast group (Internet Group Management Protocol, IGMP).Gmb represents that interface and the interface protocol between BM-SC and the GGSN is exclusively used in transmission MBMS signaling parameter.Gr represents the interface between SGSN and the HLR.Iu represents the interface between SGSN and the UTRAN.Iu/Gb represents the interface between SGSN and the GERAN.UE is connected communication with Um Interface with UTRAN, GERAN by Uu respectively.
