Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, the technical scheme embodiment of the present invention being provided referring to accompanying drawing is elaborated.
Refer to Fig. 1, the TMC message conversion providing for the embodiment of the present invention is the method flow diagram of TPEG message, and the method comprises:
Step 101: be traffic events agreement (Traffic Event Compact, TEC) message by the TMC message conversion in TMC message groups;
Step 102: the TEC message that step 101 is converted to is encapsulated as TEC assembly;
Step 103: the serviced component information of obtaining TEC assembly;
Step 104: serviced component information and preset information on services are encapsulated into service and the network information (Service and Network Information, SNI) assembly;
In embodiments of the present invention, described serviced component information comprises: the serviced component ID (SCID) of each TEC assembly, content ID (COID) and application ID (AID, AID is defined by TPEG specification, the AID=0005 of TEC for example), wherein, SCID need to extract from the serviced component framework head of TEC assembly; AID is default fixed value 0005; A plurality of TEC assemblies that COID encapsulates for same TPEG message, the COID of each TEC is distributed by SNI processing module; Preset information on services comprises: service provider's title, service describing etc., are constant.
Step 105: be TPEG message by SNI assembly and TEC component package.
The TMC message conversion providing for the invention process example is above the method for TPEG message, the method adopts TMC message as the data source of TEPG message, take full advantage of the resource of existing TMC Real-time Traffic Information service system, avoided quality assessment process, greatly reduce TPEG development cost.
The TMC message conversion providing for the embodiment of the present invention is above the method for TPEG message, below in conjunction with accompanying drawing, to said method, adopts the specific implementation process of technological means to be described in detail.
Refer to Fig. 2, the TMC message conversion providing for the embodiment of the present invention is the method flow diagram of TEC message, and the method comprises:
Step 201: from TMC message groups, read a TMC message;
In actual applications, TMC message groups can provide with text (.txt) form, and a line of text is recorded as a TMC message, and each property value of a TMC message separates with comma, and table 1 is the attribute list of TMC message.
The attribute list of table 1TMC message
Step 202: extract TMC event code the TMC message reading from step 201;
Step 203: in preset TMC-TEC event mapping table, search and whether have record corresponding to described TMC event code, if had, enter step 204, if do not had, enter step 209;
Refer to table 2, the part of the TMC-TEC event mapping table providing for the embodiment of the present invention for example.
Table 2TMC-TEC event mapping table
In actual applications, the event of TMC-TEC shown in table 2 mapping table can be designed to xml configuration file, and its form is as follows:
Wherein, evCode represents TMC event code; Event represents TMC event description; Effect represents the TEC events affecting code that this TMC event is corresponding; Cause represents the TEC event main cause code that this TMC event is corresponding; WarnLev represents the TEC event alert grade that this TMC event is corresponding; SubCause represents the detailed reason code of TEC event that this TMC event is corresponding.
Step 204: judge whether the TEC events affecting code in TMC event code corresponding record is zero, if so, enters step 209, if not, enters step 205;
Execution step 204 is for fear of occurring invalid TEC message, in actual applications, also can, in the rear direct execution step 205 of step 203, not affecting the realization of the embodiment of the present invention.
TMC-TEC event mapping table is known as shown in Table 2, and when TEC events affecting code corresponding to TMC event code is zero, other yard of value of TEC event is also zero, can think that TMC event does not have corresponding TEC event, does not change this TMC message.
Step 205: according to the TEC event attribute value in TMC event code corresponding record, build TEC event container;
TEC event container, refers to table 3, builds TEC event container and comprises: according to the TEC event attribute value in TMC event code corresponding record, be the respective attributes field assignment in TEC event container; Computation module length value, and according to the value calculating, be the length component field assignment in TEC event container.
Illustrating according to TEC event attribute value, is the respective attributes field assignment procedure in TEC event container.Such as, TMC event code is 136, and the 2 TEC events affecting code values that can obtain TMC event code 136 correspondences of tabling look-up are 1, and reason code value is 1, alert level value is 1, in detail cause value is 0, in the TEC event container after assignment, affects code, reason code, alert level and the in detail value of reason are 1,1,1,0.。
Step 206: according to the positional information of extracting the TMC message reading from step 201, build TEC reference by location container (Location Referencing Container, LRC), described positional information comprises home position, direction and the scope of TMC message;
LRC, refer to table 3, the fields such as the assembly ID of LRC and risk distance adopt preset value or default value, the process of structure LRC and the above similar process of described structure TEC event container, first according to the positional information of extracting from TMC message, the position ID to LRC, direction and scope assignment, calculate again the length component value of LRC, the length component field assignment that is LRC according to calculated value.
Step 207: for TEC message assignment messages ID and revision ID, according to described message id and revision ID, build TEC management container;
Note, the message id of each TEC message and revision ID are unique and do not repeat within a period of time.
Step 208: according to TEC event container, TEC LRC and TEC management container, build a TEC message;
Step 209: judge the TMC message whether not reading in addition in described TMC message groups, if had, return to step 201, if do not had, finish this flow process.
What provide for the embodiment of the present invention above is the method for TEC message by TMC message conversion, after TMC message transformation being TEC message by said method, need further TEC message to be encapsulated as to TEC assembly, in actual applications, can adopt following two kinds of modes that TEC message is encapsulated as to TEC assembly:
First kind of way, a TMC message conversion in TMC message groups is a TEC message after, carry out TEC component package one time, if adopt this kind of mode, after step 208, be introduced into the flow process that shown in Fig. 3, TEC message is encapsulated as to TEC assembly, then enter step 209;
The second way, TMC message all in TMC message groups is all converted to after TEC message, carry out again TEC component package, if adopt this kind of mode, in the rear direct execution step 209 of step 208, until TMC message all in TMC message groups is all converted to TEC message, then enter the flow process that shown in Fig. 4, TEC message is encapsulated as to TEC assembly.
Referring to table 3, be TEC assembly form shfft, a TEC assembly can take the data space of 65535 bytes at most, takies byte number do not exceed under 65535 prerequisite at TEC assembly, and a TEC assembly can encapsulate many TEC message.Wherein, the SCID of TEC assembly is arranged voluntarily by service provider, the method that SCID is set that the embodiment of the present invention provides is: the static variable that a SCID is set in SNI processing module, while creating a TEC assembly, to the request of SNI module, a SCID carries out field assignment, and the SCID static variable in SNI module adds 1. automatically
