Abstract
The invention discloses a multimedia broadcast multicast service(MBMS) broadcasting method and a system. The method comprises: a broadcast multicast service center (BM-SC) receives broadcast location information from a third-party network element; and the BM-SC broadcasts an MBMS service in a broadcast region indicated by the broadcast location information. According to the invention, problems of low security and a waste of broadcasting resources can be solved.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of MBMS (multi-medium broadcast/group broadcast) service broadcast method
And system.
Background technology
In order to effectively utilize mobile network resource, existing mobile communication system proposes using broadcast group broadcast transmission services
Thought, i.e. adopt MBMS.MBMS provides a data source in a mobile network and sends the point of data to many to multiple users
Point business, it is achieved thereby that network resources locating, improves the utilization rate of Internet resources, the utilization of interface resource of especially eating dishes without rice or wine
Rate.
MBMS provides two ways：Broadcast mode and multicast mode.Broadcast mode is a kind of unidirectional point-to-points points
According to (such as：Text, audio frequency, image, video etc.) sending method, the object of broadcast is all users of broadcast area.Broadcast mould
Formula sufficiently make use of wireless and network resource, because data is to send in public wireless channel.The transmission of data must
Must self adaptation RAN ability or available Radio Resource, such as when resource is nervous, MBMS data can be reduced
Bit rate.The same with broadcast mode, the MBMS data under multicast pattern sends also should be with RAN and Radio Resource phase
Join.Such as the nervous occasion of resource can also be adapted to by reducing data；A kind of multicast service perhaps has multiple multicast conversations.
Generally, for the stronger streaming media service of some real-times, only one of which conversation procedure, and for some non real-time nature
Download type text data business, can have multiple sessions within cycle preset time.
MBMS not only enables message class multicast and the broadcast of plain text low rate, but also enables high-speed multimedia industry
The multicast of business and broadcast.BM-SC (Broadcast Multicast Service Centre, broadcast multicast service center) is main
There is provided and distribution MBMS：As the entrance of content provider, for authorizing and initiating MBMS in mobile network to carry business,
Scheduling and transmission MBMS content etc..Packet service GPRS (general packet radio service) (GPRS) supporting node (Service GSN, referred to as
) and mobile management unit (Mobility Management Entity, referred to as MME) Main Function is SGSN：Send MBMS
Data is to UTRAN/E-UTRAN；To each UE, provide MBMS carrying service control function.Radio Access Network and user set
Standby both increase MBMS function, and define new logic shared channel and share realizing interface-free resources.
Under mobile communication system, the network architecture using MBMS is as shown in Figure 1.The network of MBMS includes：E-UTRAN

What M2M defined in the narrow sense is the communication of machine to machine.Broadly define is to be with machine terminal intelligent interaction
Core, networking application and service.M2M is based on intelligent machine terminal, with communication for accessing means, for visitor
The informatization resolve scheme that family provides, for meeting the information to aspects such as monitoring, command scheduling, data acquisition and measurements for the client
Change demand.Data communication between one or more machines is referred to as machine type communication (MTC, Machine Type
Communication), in this case less need for human-computer interaction.Participate in the machine of MTC, referred to as MTC device.MTC device is
The terminal of MTC user, can be communicated with MTC device, MTC gateway/MTC server by PLMN network.MTC gateway (GW,
Gate Way) for MTC server access gateway, this gateway is Virtual NE, can be for single network element it is also possible to and MTC
Server closes and sets.
Under some application scenarios (as water meter, ammeter etc.), MTC device Numerous, and apply determined MTC to set by it
Do not need Always Online" when having, only in applications trigger, MTC device is just interacted with the application by network, carry out corresponding
Response, such as reported data etc..MTC device can be by group triggering it is also possible to press area triggering.Terminal has and connects under off-line state
Receive the ability of broadcast.
In prior art, MTC device is triggered by region by Cell Broadcast CB.MTC device in region is received
Establish the link to after broadcast, initiation is interacted with application server.By Cell Broadcast CB have the shortcomings that one fatal be in region
All devices can receive broadcast, and safety cannot ensure.And configuration data is issued, the renewal of software or regard
Frequently/stream etc. cannot be realized by broadcast, if by common service chaining, will take substantial amounts of Internet resources.Therefore, here
MBMS is preferably used for MTC device under scene.When broadcast multicast services center carries out MBMS at present, its region is believed
Breath is configuration.But if based on during group broadcast, in group, equipment region is probably joined than broadcast multicast services center
The region put is little.Therefore, if broadcast will waste broadcast resource in the big region of configuration.
From the foregoing, it will be observed that in prior art, BM-SC is according to the fixing broadcast zone information being locally pre-configured with come broadcasting MBMS
Business, consequently, it is possible to causing safety relatively low, the problem of waste of resource broadcast.
