The invention solves national business and want to broadcast in China, must obtain the problem that each Local Area Network network operator allows.A kind of method that is applied in graded signal transmission in the mobile media broadcasting network is provided, can satisfies the needs of national broadcasting service better.
Say on the whole, the present invention at first needs to set up one and covers nationwide hierarchical network, promptly according to the requirement that covers the region, whole mobile multimedia broadcast system is divided into multistage network structure, make on the region the one or more undernets of higher level's network coverage; Simultaneously, for the network in the networks at different levels all disposes independently multiplexer and transmitter, and be the different basic carrier frequency of network configuration at different levels.
Like this, the business of higher level's network is finished data flow after multiplexing at the multiplexer of network at the corresponding levels, just can directly send to all terminals in the network's coverage area at the corresponding levels via network transmitter at the corresponding levels, or deliver to via distributing network on the transmitter of undernet, send to all terminals in this net overlay area via the undernet transmitter again.
And aspect reception, after receiving terminal enters whole mobile media broadcasting network, can judge that this terminal is the zone that only is positioned at higher level's network coverage, still be positioned at the common zone that covers of higher level's network and undernet; If only be positioned at higher level's network's coverage area, then this terminal can only receive the business of higher level's network, selects to wish the program of reception according to the control information on the basic carrier frequency; If terminal is positioned at higher level's network and the common zone that covers of undernet, then this terminal both can receive the business of higher level's network, also can receive the business of undernet.
And when receiving terminal breaks away from the undernet overlay area, then can interrupt current service, and forwarding the basic carrier frequency of higher level's network then to, the prompting user reselects.
Below, the embodiment that transmits with a two-level network signal further specifies the present invention.
With reference to figure 2, can comprise the steps:
The first step, network hierarchy and resource distribution.
In the middle of present embodiment, according to the requirement that covers the region, whole mobile multimedia broadcast system is divided into the two-level network structure, be that whole network layer is divided into a primary network station (network's coverage area is bigger, country for example) and a plurality of two grade network (each network's coverage area is less, for example province or a city or a littler zone); Each network all has independently multiplexer, finishes data flow multiplexing of corresponding Overhead and business datum; Each network in the two grade network all has ground supplement translator/transmitter, wherein, primary network station can use the ground supplement translator/transmitter in all two grade networks, and a two grade network can only use the ground supplement translator/transmitter in this two grade network; The shared air frequencies resource of networks at different levels is responsible for distribution by national operator, and the shared air resource of each business/program of networks at different levels is responsible for distribution by network manager at the corresponding levels.
Second step, the data multiplex of network and signal transmission.
Business/the program of primary network station is finished data flow after multiplexing at the primary network station multiplexer, comprises Overhead and business datum, can have following two paths to arrive broadcast terminal:
One paths is the down link by primary network station, directly sends to all mobile multi-media broadcast terminals in the primary network station coverage by primary network station satellite broadcasting transmitter;
Another paths is to deliver on the ground supplement translator/transmitter of each two grade network through the distributing network of primary network station, sends to the interior mobile multi-media broadcast terminal of each two grade network scope through ground supplement translator/transmitter down link.
And the regional service/program of a two grade network is finished data flow after multiplexing at the two grade network multiplexer, send on the ground supplement translator/transmitter in the two grade network, send to all mobile multi-media broadcast terminals in the two grade network coverage by its down link again.
In the 3rd step, the signal of portable terminal receives.
After portable terminal enters whole mobile media broadcasting network, judge that this terminal is only to be positioned at the zone that primary network station covers, still be positioned at the common zone that covers of a primary network station and two grade network.
If only be positioned at the primary network station overlay area, then this terminal can only receive the business of primary network station, selects to wish the program of reception according to the control information on the basic carrier frequency.
If terminal is positioned at primary network station and the common zone that covers of two grade network, then this terminal both can receive the business of primary network station, also can receive the business of two grade network.
When if terminal breaks away from the two grade network overlay area, interrupt current service, forward the basic carrier frequency of primary network station then to, the prompting user reselects.
Wherein, air frequencies resource and the distribution thereof mentioned in the middle of the above-mentioned first step are meant that the different levels network uses different frequency to carry out services/data and transmits, and this frequency becomes carrier frequency.Wherein every layer network can use a plurality of carrier frequency, in the case, should specify a carrier frequency as basic carrier frequency.In the middle of present embodiment, the basic carrier frequency of primary network station is f1, and the basic carrier frequency that primary network station uses can not be used by two grade network; The carrier frequency that different two grade networks uses can be identical, also can be different.As shown in Figure 3, two grade network 2A uses the identical basic carrier frequency f2 of two grade network with 2B, has showed the air frequencies resource allocation of Mobile Multimedia Broadcasting hierarchical network.
When two grade network uses a plurality of carrier frequency, should specify the basic carrier frequency of a carrier frequency equally as two grade network, the business of two grade network at first is chosen on the basic carrier frequency of two grade network and carries, unless just do not have enough capacity to use other carrier frequency of two grade network on the basic carrier frequency of two grade network.
In the control information of on the basic carrier frequency of primary network station, being carried, except the essential various control informations of this carrier frequency, also comprised descriptor and the descriptor of the basic carrier frequency of two grade network, for example frequency information, the bandwidth information etc. of other carrier frequency in the primary network station; Because the selection of the basic carrier frequency of two grade network has two kinds of schemes, so the basic carrier frequency descriptor of the two grade network that provides in the primary network station also has two kinds of situations:
First kind of situation is all two grade networks when using the basic carrier frequency of same frequencys, and the descriptor of a basic carrier frequency of two grade network only need be provided in the primary network station this moment;
Another kind of situation is a different two grade network when using the basic carrier frequency of different frequency, and the descriptor of one group of basic carrier frequency of two grade network should be provided in the primary network station.
In the middle of the step 3 of embodiment, portable terminal can selectivity receive Mobile Multimedia Broadcasting net (primary network station or two grade network) business/program according to the difference of its present position, as shown in Figure 4:
When terminal was brought into use the service of Mobile Multimedia Broadcasting net, terminal at first inserted the basic carrier frequency of primary network station, selected oneself to wish to receive some programs according to the control information on the basic carrier frequency;
When terminal is positioned at a two grade network overlay area simultaneously, except the program that receives this two grade network, can also receive the program of primary network station, can receive the business of primary network station and the business of two grade network 2A as the terminal a among the figure, terminal 2b and terminal 2c can receive the business of primary network station and two grade network equally;
When terminal only is positioned at the overlay area of primary network station, can only receive the business of primary network station, for example the terminal d among the figure;
When terminal is being used the service of some two grade network 2A, but when the situation of overlay area of two grade network 2A takes place to break away from, terminal prompting user current service earlier will be interrupted or directly be interrupted, and forward to then on the primary network station and point out the user to reselect on the basic carrier frequency.
The method of the hierarchical transmission of a kind of mobile media broadcasting network of the present invention, also other various embodiments can be arranged, be not restricted to listed utilization in specification and the execution mode, it can be applied to various suitable the present invention's field fully, for those skilled in the art, can easily realize additional advantage and make amendment, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the present invention is not limited to specific details, representational equipment and the examples shown that illustrates here and describe.
