Embodiment
The present invention is in order to solve the drawback that conventional solution exists, further set forth the receiving handling method of a kind of mobile multi-media terminal ESG data message of the present invention by following specific embodiment, below embodiment is described in detail, but not as a limitation of the invention.
As shown in Figure 1, form schematic diagram for ESG.In mobile multimedia broadcast system, ESG is made of basic descriptor, data message and program prompt information, data message is the main body of ESG, has described the business information relevant with mobile multi-media broadcasting service, professional extend information, arrangement information, content information and business parameters data.
Simultaneously, as shown in Figure 2, for the ESG data message is cut apart schematic diagram, in mobile multimedia broadcast system, the ESG data message is divided according to type, be divided into business information class, professional extend information class, arrangement information class, content information class and business parameters data class etc., distinguish by the data type identification field; Sorted data message is cut apart by piece, distinguished by the data block identification field; Data block is divided into some joints, distinguishes by the joint sequence number field, and data section is corresponding one by one with the data cell of multiplexed sub frame.
As shown in Figure 3, be the basic description list encapsulating structure of ESG schematic diagram; As shown in Figure 4, for the basic description list of ESG takies the schematic diagram of control logic Channel Transmission, also be multiplexed frame payload (MF_ID==0) schematic diagram.At the Mobile Multimedia Broadcasting front end, multiplexer equipment encapsulates the structure of the basic description list of ESG by Fig. 3, and the basic description list of this ESG after will encapsulating is encapsulated in the control logic channel as shown in Figure 4;
As shown in Figure 5, be the encapsulating structure schematic diagram of ESG data message in data cell; As shown in Figure 6, be the encapsulating structure schematic diagram of ESG data message at the transmission data segment.Multiplexer equipment is encapsulated in the encapsulating structure of ESG data message according to accompanying drawing 5 in the special-purpose ESG service logical channels data segment data cell, and its special-purpose ESG service logical channels data segment is structure as shown in Figure 6; Form multiplexed sub frame then, the recomposition multiplexed frame issues by mobile media broadcasting network.
As shown in Figure 7, the ESG data message receives handling process in the embodiment of the invention, may further comprise the steps:
Step 100 receives and handles the basic description list of ESG;
The basic description list of ESG as shown in Figure 4 takies the control logic channel and transmits, terminal receives mobile multi-media service first, receive the basic description list data of ESG from the control logic channel (MF_ID=0) of basic frequency, the basic description list table of ESG identification number is " 0x06 ";
Terminal is according to the encapsulating structure of as shown in Figure 3 the basic description list of ESG, from the basic description list of ESG, parse the service identification (ServiceID) of ESG indication information, be that the ESG data message transmits in which service logical channels, just obtain ServiceID, general ESG is in one or two service logical channels transmission;
Terminal parses ESG data type information, the data block information of ESG indication information once more according to the encapsulating structure of as shown in Figure 3 the basic description list of ESG from the basic description list of ESG; The ESG data type information is corresponding data type identification (differentiated service element, professional extensible element, layout element, content element, a service parameter element); Data block information comprises data block sign (different pieces of information of corresponding same data type is such as the data of layout table one day), data block version number; Corresponding these types of elements data are in which service logical channels transmission information, and record;
Step 200 receives and handles the ESG data message;
The ServieID that terminal is obtained according to above-mentioned steps 100 switches to corresponding ESG service logical channels, data segment structure in its ESG service logical channels as shown in Figure 6, from multiplexed sub frame reading of data paragraph header, the reading of data cell type is the data cell of " 0 " successively;
Terminal according to as shown in Figure 5 ESG data message at the data cell encapsulating structure, from data cell, extract the data section of the data block sign of corresponding data type respectively, (mode that the ESG front end adopts wheel to broadcast periodically sends the ESG data message to collect all data section of specified data block up to whole joints, terminal is if receive uneven in one-period, can wait several cycles more), be merged into data block; If the ESG data block has adopted compression algorithm, terminal also needs according to compression algorithm indication decompressed data piece; After terminal is collected neat all data blocks, need save as the ESG XML file of corresponding data type according to data block type, data block sequence number splicing assembling ESG data message;
Terminal notifying user ESG receives successfully, writes down the version number of each ESG data type (business, professional expansion, layout, content, service parameter) corresponding data block identification, data block;
Step 300, terminal parses ESG XML file shows ESG information, the user browses ESG information, select professional corresponding service sign ServiceID to switch to service logical channels according to ESG, receive the processing mobile multimedia and look data such as audio frequency, use the mobile multi-media service service.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
